 ## Running the Bridge
 
-To run the Bridge you need to be able to connect the bridge relay node to the RPC interface of nodes on each side of the
-bridge (source and target chain).
-
-There are 2 ways to run the bridge, described below:
-
-- building & running from source: with this option, you'll be able to run the bridge between two standalone chains that
-are running GRANDPA finality gadget to achieve finality;
-
-- running a Docker Compose setup: this is a recommended option, where you'll see bridges with parachains, complex relays
-and more.
-
-### Using the Source
-
-First you'll need to build the bridge nodes and relay. This can be done as follows:
-
-```bash
-# In `parity-bridges-common` folder
-cargo build -p rialto-bridge-node
-cargo build -p millau-bridge-node
-cargo build -p substrate-relay
-```
-
-### Running a Dev network
-
-We will launch a dev network to demonstrate how to relay a message between two Substrate based chains (named Rialto and
-Millau).
-
-To do this we will need two nodes, two relayers which will relay headers, and two relayers which will relay messages.
-
-#### Running from local scripts
-
-To run a simple dev network you can use the scripts located in the [`deployments/local-scripts`
-folder](./deployments/local-scripts).
-
-First, we must run the two Substrate nodes.
-
-```bash
-# In `parity-bridges-common` folder
-./deployments/local-scripts/run-rialto-node.sh
-./deployments/local-scripts/run-millau-node.sh
-```
-
-After the nodes are up we can run the header relayers.
-
-```bash
-./deployments/local-scripts/relay-millau-to-rialto.sh
-./deployments/local-scripts/relay-rialto-to-millau.sh
-```
-
-At this point you should see the relayer submitting headers from the Millau Substrate chain to the Rialto Substrate
-chain.
-
-```
-# Header Relayer Logs
-[Millau_to_Rialto_Sync] [date] DEBUG bridge Going to submit finality proof of Millau header #147 to Rialto
-[...] [date] INFO bridge Synced 147 of 147 headers
-[...] [date] DEBUG bridge Going to submit finality proof of Millau header #148 to Rialto
-[...] [date] INFO bridge Synced 148 of 149 headers
-```
-
-Finally, we can run the message relayers.
-
-```bash
-./deployments/local-scripts/relay-messages-millau-to-rialto.sh
-./deployments/local-scripts/relay-messages-rialto-to-millau.sh
-```
-
-You will also see the message lane relayers listening for new messages.
-
-```
-# Message Relayer Logs
-[Millau_to_Rialto_MessageLane_00000000] [date] DEBUG bridge Asking Millau::ReceivingConfirmationsDelivery about best message nonces
-[...] [date] INFO bridge Synced Some(2) of Some(3) nonces in Millau::MessagesDelivery -> Rialto::MessagesDelivery race
-[...] [date] DEBUG bridge Asking Millau::MessagesDelivery about message nonces
-[...] [date] DEBUG bridge Received best nonces from Millau::ReceivingConfirmationsDelivery: TargetClientNonces {
-	  latest_nonce: 0, nonces_data: () }
-[...] [date] DEBUG bridge Asking Millau::ReceivingConfirmationsDelivery about finalized message nonces
-[...] [date] DEBUG bridge Received finalized nonces from Millau::ReceivingConfirmationsDelivery: TargetClientNonces {
-	  latest_nonce: 0, nonces_data: () }
-[...] [date] DEBUG bridge Received nonces from Millau::MessagesDelivery: SourceClientNonces { new_nonces: {}, confirmed_nonce: Some(0) }
-[...] [date] DEBUG bridge Asking Millau node about its state
-[...] [date] DEBUG bridge Received state from Millau node: ClientState { best_self: HeaderId(1593, 0xacac***), best_finalized_self:
-       HeaderId(1590, 0x0be81d...), best_finalized_peer_at_best_self: HeaderId(0, 0xdcdd89...) }
-```
-
-To send a message see the ["How to send a message" section](#how-to-send-a-message).
-
-### How to send a message
-
-In this section we'll show you how to quickly send a bridge message. The message is just an encoded XCM `Trap(43)`
-message.
-
-```bash
-# In `parity-bridges-common` folder
-./scripts/send-message-from-millau-rialto.sh
-```
-
-After sending a message you will see the following logs showing a message was successfully sent:
-
-```
-INFO bridge Sending message to Rialto. Size: 11.
-TRACE bridge Sent transaction to Millau node: 0x5e68...
-```
-
-And at the Rialto node logs you'll something like this:
-
-```
-... runtime::bridge-messages: Received messages: total=1, valid=1. Weight used: Weight(ref_time: 1215065371, proof_size:
-    48559)/Weight(ref_time: 1215065371, proof_size: 54703).
-```
-
-It means that the message has been delivered and dispatched. Message may be dispatched with an error, though - the goal
-of our test bridge is to ensure that messages are successfully delivered and all involved components are working.
-
-## Full Network Docker Compose Setup
-
-For a more sophisticated deployment which includes bidirectional header sync, message passing, monitoring dashboards,
-etc. see the [Deployments README](./deployments/README.md).
-
-You should note that you can find images for all the bridge components published on [Docker
-Hub](https://hub.docker.com/u/paritytech).
-
-To run a Rialto node for example, you can use the following command:
-
-```bash
-docker run -p 30333:30333 -p 9933:9933 -p 9944:9944 \
-  -it paritytech/rialto-bridge-node --dev --tmp \
-  --rpc-cors=all --unsafe-rpc-external
-```
-
-## Community
-
-Main hangout for the community is [Element](https://element.io/) (formerly Riot). Element is a chat server like, for
-example, Discord. Most discussions around Polkadot and Substrate happen in various Element "rooms" (channels). So,
-joining Element might be a good idea, anyway.
-
-If you are interested in information exchange and development of Polkadot related bridges please feel free to join the
-[Polkadot Bridges](https://app.element.io/#/room/#bridges:web3.foundation) Element channel.
-
-The [Substrate Technical](https://app.element.io/#/room/#substrate-technical:matrix.org) Element channel is most suited
-for discussions regarding Substrate itself.
+Apart from live Rococo <> Westend bridge, you may spin up local networks and test see how it works locally. More
+details may be found in
+[this document](https://github.com/paritytech/polkadot-sdk/tree/master//cumulus/parachains/runtimes/bridge-hubs/README.md).

 ## A Brief Introduction into Parachains Finality

+You can find detailed information on parachains finality in the
+[Polkadot-SDK](https://github.com/paritytech/polkadot-sdk) repository. This section gives a brief overview of how the
+parachain finality works and how to build a light client for a parachain.
 
 The main thing there is that the parachain generates blocks on its own, but it can't achieve finality without
 help of its relay chain. Instead, the parachain collators create a block and hand it over to the relay chain
 validators. Validators validate the block and register the new parachain head in the

+# Bridges Tests for Local Rococo <> Westend Bridge
+
+This folder contains [zombienet](https://github.com/paritytech/zombienet/) based integration tests for both
+onchain and offchain bridges code. Due to some
+[technical difficulties](https://github.com/paritytech/parity-bridges-common/pull/2649#issue-1965339051), we
+are using native zombienet provider, which means that you need to build some binaries locally.
+
+To start those tests, you need to:
+
+- download latest [zombienet release](https://github.com/paritytech/zombienet/releases);
+
+- build Polkadot binary by running `cargo build -p polkadot --release  --features fast-runtime` command in the
+[`polkadot-sdk`](https://github.com/paritytech/polkadot-sdk) repository clone;
+
+- build Polkadot Parachain binary by running `cargo build -p polkadot-parachain-bin --release` command in the
+[`polkadot-sdk`](https://github.com/paritytech/polkadot-sdk) repository clone;
+
+- ensure that you have [`node`](https://nodejs.org/en) installed. Additionally, we'll need globally installed
+`polkadot/api-cli` package (use `npm install -g @polkadot/api-cli@beta` to install it);
+
+- build Substrate relay by running `cargo build -p substrate-relay --release` command in the
+[`parity-bridges-common`](https://github.com/paritytech/parity-bridges-common) repository clone.
+
+- copy fresh `substrate-relay` binary, built in previous point, to the `~/local_bridge_testing/bin/substrate-relay`;
+
+- change the `POLKADOT_SDK_FOLDER` and `ZOMBIENET_BINARY_PATH` (and ensure that the nearby variables
+have correct values) in the `./run-tests.sh`.
+
+After that, you could run tests with the `./run-tests.sh` command. Hopefully, it'll show the
+"All tests have completed successfully" message in the end. Otherwise, it'll print paths to zombienet
+process logs, which, in turn, may be used to track locations of all spinned relay and parachain nodes.

-# Release Checklist - Runtimes
-
-**All** following checks must be completed before publishing a new release.
-The release process is owned and led by @paritytech/release-engineering team.
-The checks marked with :crab: are meant to be checked by [a runtime engineer](https://github.com/paritytech/cumulus/issues/1761).
-
-## Runtimes Release
-
-### Codebase
-These checks should be performed on the codebase.
-
-- [ ] the [`spec_version`](https://github.com/paritytech/cumulus/blob/master/docs/release.md#spec-version) has been incremented since the
-    last release for any native runtimes from any existing use on public (non-private/test) networks
-- [ ] :crab: previously [completed migrations](https://github.com/paritytech/cumulus/blob/master/docs/release.md#old-migrations-removed) are removed for any public (non-private/test) networks
-- [ ] pallet and [extrinsic ordering](https://github.com/paritytech/cumulus/blob/master/docs/release.md#extrinsic-ordering--storage) as well as `SignedExtension`s have stayed
-    the same. Bump `transaction_version` otherwise
-- [ ] the [benchmarks](https://github.com/paritytech/ci_cd/wiki/Benchmarks:-cumulus) ran
-- [ ] the weights have been updated for any modified runtime logic
-- [ ] :crab: the new weights are sane, there are no significant (>50%) drops or rises with no reason
-- [ ] :crab: XCM config is compatible with the configurations and versions of relevant interlocutors, like the Relay Chain.
-
-### On the release branch
-
-The following checks can be performed after we have forked off to the release-candidate branch or started an additional release candidate branch (rc-2, rc-3, etc)
-
-- [ ] Verify [new migrations](https://github.com/paritytech/cumulus/blob/master/docs/release.md#new-migrations) complete successfully, and the
-    runtime state is correctly updated for any public (non-private/test)
-    networks
-- [ ] Run [integration tests](https://github.com/paritytech/cumulus/blob/master/docs/release.md#integration-tests), and make sure they pass.
-- [ ] Push runtime upgrade to Asset Hub Westend and verify network stability
-- [ ] Push runtime upgrade to Collectives and verify network stability
-- [ ] Push runtime upgrade to Bridge-Hub-Kusama and verify network stability
-
-
-### Github
-
-- [ ] Check that a draft release has been created at the [Github Releases page](https://github.com/paritytech/cumulus/releases) with relevant [release
-    notes](https://github.com/paritytech/cumulus/blob/master/docs/release.md#release-notes)
-- [ ] Check that [build artifacts](https://github.com/paritytech/cumulus/blob/master/docs/release.md#build-artifacts) have been added to the
-    draft-release.
-
-# Post release
-
-- [ ] :crab: all commits (runtime version bumps, fixes) on this release branch have been merged back to master.

-	///
-	/// There are two obvious "modes" that we could apportion `max_weight`: one would be to attempt

-	/// second channel's first page and so on until finally we cycle back and the process messages
-	/// on the first channel's second page &c. The other mode would be to apportion only `1/N` of
-	/// `max_weight` for the first page (where `N` could be, perhaps, the number of channels to
-	/// service, using the remainder plus the next `1/N` for the next channel's page &c.
-	///
-	/// Both modes have good qualities, the first ensures that a channel with a large message (over
-	/// `1/N` does not get indefinitely blocked if other channels have continuous, light traffic.
-	/// The second is fairer, and ensures that channels with continuous light messages don't suffer
-	/// high latency.
-	///
-	/// The following code is a hybrid solution; we have a concept of `weight_available` which
-	/// incrementally approaches `max_weight` as more channels are attempted to be processed. We use
-	/// the parameter `weight_restrict_decay` to control the speed with which `weight_available`
-	/// approaches `max_weight`, with `0` being strictly equivalent to the first aforementioned
-	/// mode, and `N` approximating the second. A reasonable parameter may be `1`, which makes
-	/// half of the `max_weight` available for the first page, then a quarter plus the remainder
-	/// for the second &c. though empirical and or practical factors may give rise to adjusting it

-E2E tests concerning Polkadot Governance and the Collectives Parachain. The tests run by the Parachain Integration Tests
-[tool](https://github.com/paritytech/parachains-integration-tests/).
-
-# Requirements
-The tests require some changes to the regular production runtime builds:
-
-## RelayChain runtime
-1. Alice has SUDO
-2. Public Referenda `StakingAdmin`, `FellowshipAdmin` tracks settings (see the corresponding keys of the `TRACKS_DATA`
-   constant in the `governance::tracks` module of the Relay Chain runtime crate):
-``` yaml
-prepare_period: 5 Block,
-decision_period: 1 Block,
-confirm_period: 1 Block,
-min_enactment_period: 1 Block,
-```
-
-## Collectives runtime
-1. Fellowship Referenda `Fellows` track settings (see the corresponding key of the `TRACKS_DATA` constant in the
-   `fellowship::tracks` module of the Collectives runtime crate):
-``` yaml
-prepare_period: 5 Block,
-decision_period: 1 Block,
-confirm_period: 1 Block,
-min_enactment_period: 1 Block,

+//! Managed Collective Content Pallet
+//!
+//! The pallet provides the functionality to store different types of content. This would typically
+//! be used by an on-chain collective, such as the Polkadot Alliance or Ambassador Program.
+//!
+//! The pallet stores content as an [OpaqueCid], which should correspond to some off-chain hosting
+//! service, such as IPFS, and contain any type of data. Each type of content has its own origin
+//! from which it can be managed. The origins are configurable in the runtime. Storing content does
+//! not require a deposit, as it is expected to be managed by a trusted collective.
+//!
+//! Content types:
+//!
+//! - Collective [charter](pallet::Charter): A single document (`OpaqueCid`) managed by
+//!   [CharterOrigin](pallet::Config::CharterOrigin).
+//! - Collective [announcements](pallet::Announcements): A list of announcements managed by
+//!   [AnnouncementOrigin](pallet::Config::AnnouncementOrigin).

-//! # Asset Hub Polkadot Runtime
-//!
-//! Asset Hub Polkadot is a parachain that provides an interface to create, manage, and use assets.
-//! Assets may be fungible or non-fungible.
-//!
-//! ## Renaming
-//!
-//! This chain was originally known as "Statemint". You may see references to Statemint, Statemine,
-//! and Westmint throughout the codebase. These are synonymous with "Asset Hub Polkadot, Kusama, and
-//! Westend", respectively.
-//!
-//! ## Assets
-//!
-//! - Fungibles: Configuration of `pallet-assets`.
-//! - Non-Fungibles (NFTs): Configuration of `pallet-uniques`.
-//!
-//! ## Other Functionality
-//!
-//! ### Native Balances
-//!
-//! Asset Hub Polkadot uses its parent DOT token as its native asset.
-//!
-//! ### Governance
-//!
-//! As a system parachain, Asset Hub defers its governance (namely, its `Root` origin), to its
-//! Relay Chain parent, Polkadot.
-//!
-//! ### Collator Selection
-//!
-//! Asset Hub uses `pallet-collator-selection`, a simple first-come-first-served registration
-//! system where collators can reserve a small bond to join the block producer set. There is no
-//! slashing.
-//!
-//! ### XCM
-//!
-//! Because Asset Hub is fully under the control of the Relay Chain, it is meant to be a
-//! `TrustedTeleporter`. It can also serve as a reserve location to other parachains for DOT as well
-//! as other local assets.

+//! The Ambassador Program.
+//!
+//! The module defines the following on-chain functionality of the Ambassador Program:
+//!
+//! - Managed set of program members, where every member has a [rank](ranks)
+//! (via [AmbassadorCollective](pallet_ranked_collective)).
+//! - Referendum functionality for the program members to propose, vote on, and execute
+//! proposals on behalf of the members of a certain [rank](Origin)
+//! (via [AmbassadorReferenda](pallet_referenda)).
+//! - Managed content (charter, announcements) (via [pallet_collective_content]).
+//! - Promotion and demotion periods, register of members' activity, and rank based salaries
+//! (via [AmbassadorCore](pallet_core_fellowship)).
+//! - Members' salaries (via [AmbassadorSalary](pallet_salary), requiring a member to be
+//! imported or inducted into [AmbassadorCore](pallet_core_fellowship)).

-# Changelog
-
-Currently, the changelog is built locally. It will be moved to CI once labels stabilize.
-
-For now, a bit of preparation is required before you can run the script:
-- fetch the srtool digests
-- store them under the `digests` folder as `<chain>-srtool-digest.json`
-- ensure the `.env` file is up to date with correct information
-
-The content of the release notes is generated from the template files under the `scripts/ci/changelog/templates` folder.
-For readability and maintenance, the template is split into several small snippets.
-
-Run:
-```
-./bin/changelog <ref_since> [<ref_until>=HEAD]
-```
-
-For instance:
-```
-./bin/changelog parachains-v7.0.0-rc8
-```
-
-A file called `release-notes.md` will be generated and can be used for the release.
-
-## ENV
-
-You may use the following ENV for testing:
-
-```
-RUSTC_STABLE="rustc 1.56.1 (59eed8a2a 2021-11-01)"
-RUSTC_NIGHTLY="rustc 1.57.0-nightly (51e514c0f 2021-09-12)"
-PRE_RELEASE=true
-HIDE_SRTOOL_ROCOCO=true
-HIDE_SRTOOL_SHELL=true
-REF1=statemine-v5.0.0
-REF2=HEAD
-DEBUG=1
-NO_CACHE=1
-```
-
-By default, the template will include all the information, including the runtime data. For clients releases, we don't
-need those and they can be skipped by setting the following env:
-```
-RELEASE_TYPE=client
-```
-
-## Considered labels
-
-The following list will likely evolve over time and it will be hard to keep it in sync. In any case, if you want to find
-all the labels that are used, search for `meta` in the templates. Currently, the considered labels are:
-
-- Priority: C<N> labels
-- Audit: D<N> labels
-- E4 => new host function
-- B0 => silent, not showing up
-- B1-releasenotes (misc unless other labels)
-- B5-client (client changes)
-- B7-runtimenoteworthy (runtime changes)
-- T6-XCM
-
-Note that labels with the same letter are mutually exclusive. A PR should not have both `B0` and `B5`, or both `C1` and
-`C9`. In case of conflicts, the template will decide which label will be considered.
-
-## Dev and debugging
-
-### Hot Reload
-
-The following command allows **Hot Reload**:
-```
-fswatch templates -e ".*\.md$" | xargs -n1 -I{} ./bin/changelog statemine-v5.0.0
-```
-### Caching
-
-By default, if the changelog data from Github is already present, the calls to the Github API will be skipped and the
-local version of the data will be used. This is much faster. If you know that some labels have changed in Github, you
-probably want to refresh the data. You can then either delete manually the `cumulus.json` file or `export NO_CACHE=1` to
-force refreshing the data.

+# Deprecation Checklist
+
+This deprecation checklist makes sense while we don’t use [SemVer](https://semver.org/).
+After that, this document will most likely change.
+As deprecation and removal of existing code can happen on any release, we need to be mindful that external builders
+could be impacted by the changes we make.
+The deprecation checklist tries to mitigate this impact, while still keeping the developer experience, the DevEx, as
+smooth as possible.
+
+To start a deprecation process, a new issue with the label `T15-deprecation` needs to be created for correct tracking.
+Then these are the actions to take:
+
+## Hard deprecate by adding a warning message
+
+The warning message shall include a removal month and year, which is suggested to be 6 months after the deprecation
+notice is released.
+This means that the code will be removed in a release within that month (or after, but never before). Please use this
+template, doing so makes it easy to search through the code base:
+
+```rust
+#[deprecated(note = "[DEPRECATED] will be removed after [DATE]. [ALTERNATIVE]")]
+```
+`[ALTERNATIVE]` won't always be possible but offer it if it is.
+
+E.g.
+```rust
+#[deprecated(note = "`GenesisConfig` will be removed after December 2023. Use `RuntimeGenesisConfig` instead.")]
+```
+
+Some pieces of code cannot be labeled as deprecated, like [reexports](https://github.com/rust-lang/rust/issues/30827)
+or [dispatchables](https://github.com/paritytech/polkadot-sdk/issues/182#issuecomment-1691684159), for instance.
+In cases like that we can only make a visible enough comment, and make sure that we [announce the deprecation properly](#announce-the-deprecation-and-removal).
+
+## Remove usage of the deprecated code in the code base
+
+Just make sure that we are not using the deprecated code ourselves.
+If you added the deprecation warning from the previous step, this can be done by making sure that warning is not shown
+when building the code.
+
+## Update examples and tutorials
+
+Make sure that the rust docs are updated.
+We also need [https://docs.substrate.io/](https://docs.substrate.io/) to be updated accordingly. The repo behind it is
+[https://github.com/substrate-developer-hub/substrate-docs](https://github.com/substrate-developer-hub/substrate-docs).
+
+## Announce the deprecation and removal
+
+**At minimum they should be noted in the release log.** Please see how to document a PR [here](https://github.com/paritytech/polkadot-sdk/blob/master/docs/contributor/CONTRIBUTING.md#documentation).
+There you can give instructions based on the audience and tell them what they need to do to upgrade the code.
+
+Some breaking changes have a bigger impact than others. When the impact is big the release note is not enough, though
+it should still be the primary place for the notice. You can link back to the changelog files in other channels if you
+want to announce it somewhere else.
+Make sure you are as loud as you need to be for the magnitude of the breaking change.
+
+## Removal version is planned
+
+Depending on the removal date indicated in the deprecation warning in the [first step](#hard-deprecate-by-adding-a-warning-message),
+the nature and the importance of the change, it might make sense to coordinate the release with other developers and
+with the Release team.
+
+## Deprecated code is removed
+
+The deprecated code finally gets removed.
+Don’t forget to [announce this accordingly](#announce-the-deprecation-and-removal).
+
+✅ In order to not forget any of these steps, consider using this template in your deprecation issue:
+
+```markdown
+### Tasks
+
+- [ ] Deprecate code by adding a warning message
+- [ ] Remove usage of the deprecated code in the code base
+- [ ] Update examples and tutorials
+- [ ] Announce code deprecation
+- [ ] Plan removal version
+- [ ] Announce code removal
+- [ ] Remove deprecated code

+# PRDoc
+
+## Intro
+
+With the merge of [PR #1946](https://github.com/paritytech/polkadot-sdk/pull/1946), a new method for
+documenting changes has been introduced: `prdoc`. The [prdoc repository](https://github.com/paritytech/prdoc)
+contains more documentation and tooling.
+
+The current document describes how to quickly get started authoring `PRDoc` files.
+
+## Requirements
+
+When creating a PR, the author needs to decides with the `R0` label whether the change (PR) should
+appear in the release notes or not.
+
+Labelling a PR with `R0` means that no `PRDoc` is required.
+
+A PR without the `R0` label **does** require a valid `PRDoc` file to be introduced in the PR.
+
+## PRDoc how-to
+
+A `.prdoc` file is a YAML file with a defined structure (ie JSON Schema).
+
+For significant changes, a `.prdoc` file is mandatory and the file must meet the following
+requirements:
+- file named `pr_NNNN.prdoc` where `NNNN` is the PR number.
+  For convenience, those file can also contain a short description: `pr_NNNN_foobar.prdoc`.
+- located under the [`prdoc` folder](https://github.com/paritytech/polkadot-sdk/tree/master/prdoc) of the repository
+- compliant with the [JSON schema](https://json-schema.org/) defined in `prdoc/schema_user.json`
+
+Those requirements can be fulfilled manually without any tooling but a text editor.
+
+## Tooling
+
+Users might find the following helpers convenient:
+- Setup VSCode to be aware of the prdoc schema: see [using VSCode](https://github.com/paritytech/prdoc#using-vscode)
+- Using the `prdoc` cli to:
+  - generate a `PRDoc` file from a [template defined in the Polkadot SDK
+    repo](https://github.com/paritytech/polkadot-sdk/blob/master/prdoc/.template.prdoc) simply providing a PR number
+  - check the validity of one or more `PRDoc` files
+
+## `prdoc` cli usage
+
+The `prdoc` cli documentation can be found at https://github.com/paritytech/prdoc#prdoc
+
+tldr:
+- `prdoc generate <NNNN>`
+- `prdoc check -n <NNNN>`
+
+where <NNNN> is the PR number.
+
+## Pick an audience
+
+While describing a PR, the author needs to consider which audience(s) need to be addressed.
+The list of valid audiences is described and documented in the JSON schema as follow:
+
+- `Node Dev`: Those who build around the client side code. Alternative client builders, SMOLDOT, those who consume RPCs.
+   These are people who are oblivious to the runtime changes. They only care about the meta-protocol, not the protocol
+   itself.
+
+- `Runtime Dev`: All of those who rely on the runtime. A parachain team that is using a pallet. A DApp that is using a
+   pallet. These are people who care about the protocol (WASM), not the meta-protocol (client).
+
+- `Node Operator`: Those who don't write any code and only run code.
+
+- `Runtime User`: Anyone using the runtime. This can be a token holder or a dev writing a front end for a chain.
+
+## Tips
+
+The PRDoc schema is defined in each repo and usually is quite restrictive.
+You cannot simply add a new property to a `PRDoc` file unless the Schema allows it.

+//! # Currency Pallet
+//!
+//! By the end of this guide, you will write a small FRAME pallet (see
+//! [`crate::polkadot_sdk::frame_runtime`]) that is capable of handling a simple crypto-currency.
+//! This pallet will:
+//!
+//! 1. Allow anyone to mint new tokens into accounts (which is obviously not a great idea for a real
+//!    system).
+//! 2. Allow any user that owns tokens to transfer them to others.
+//! 3. Track the total issuance of all tokens at all times.
+//!
+//! > This guide will build a currency pallet from scratch using only the lowest primitives of
+//! > FRAME, and is mainly intended for education, not *applicability*. For example, almost all
+//! > FRAME-based runtimes use various techniques to re-use a currency pallet instead of writing
+//! > one. Further advance FRAME related topics are discussed in [`crate::reference_docs`].
+//!
+//! ## Topics Covered
+//!
+//! The following FRAME topics are covered in this guide. See the documentation of the
+//! associated items to know more.
+//!
+//! - [Storage](frame::pallet_macros::storage)
+//! - [Call](frame::pallet_macros::call)
+//! - [Event](frame::pallet_macros::event)
+//! - [Error](frame::pallet_macros::error)
+//! - Basics of testing a pallet
+//! - [Constructing a runtime](frame::runtime::prelude::construct_runtime)
+//!
+//! ## Writing Your First Pallet
+//!
+//! You should have studied the following modules as a prelude to this guide:
+//!
+//! - [`crate::reference_docs::blockchain_state_machines`]
+//! - [`crate::reference_docs::trait_based_programming`]
+//! - [`crate::polkadot_sdk::frame_runtime`]
+//!
+//! ### Shell Pallet
+//!
+//! Consider the following as a "shell pallet". We continue building the rest of this pallet based
+//! on this template.
+//!
+//! [`pallet::config`](frame::pallet_macros::config) and
+//! [`pallet::pallet`](frame::pallet_macros::pallet) are both mandatory parts of any pallet. Refer
+//! to the documentation of each to get an overview of what they do.
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", shell_pallet)]
+//!
+//! ### Storage
+//!
+//! First, we will need to create two onchain storage declarations.
+//!
+//! One should be a mapping from account-ids to a balance type, and one value that is the total
+//! issuance.
+//
+// For the rest of this guide, we will opt for a balance type of u128.
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", Balance)]
+//!
+//! The definition of these two storage items, based on [`frame::pallet_macros::storage`] details,
+//! is as follows:
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", TotalIssuance)]
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", Balances)]
+//!
+//! ### Dispatchables
+//!
+//! Next, we will define the dispatchable functions. As per [`frame::pallet_macros::call`], these
+//! will be defined as normal `fn`s attached to `struct Pallet`.
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", impl_pallet)]
+//!
+//! The logic of the functions is self-explanatory. Instead, we will focus on the FRAME-related
+//! details:
+//!
+//! - Where do `T::AccountId` and `T::RuntimeOrigin` come from? These are both defined in
+//!  [`frame::prelude::frame_system::Config`], therefore we can access them in `T`.
+//! - What is `ensure_signed`, and what does it do with the aforementioned `T::RuntimeOrigin`? This
+//!   is outside the scope of this guide, and you can learn more about it in the origin reference
+//!   document ([`crate::reference_docs::frame_origin`]). For now, you should only know the
+//!   signature of the function: it takes a generic `T::RuntimeOrigin` and returns a
+//!   `Result<T::AccountId, _>`. So by the end of this function call, we know that this dispatchable
+//!   was signed by `who`.
+#![doc = docify::embed!("../../substrate/frame/system/src/lib.rs", ensure_signed)]
+//!
+//!
+//! - Where does `mutate`, `get` and `insert` and other storage APIs come from? All of them are
+//! explained in the corresponding `type`, for example, for `Balances::<T>::insert`, you can look
+//! into [`frame::prelude::StorageMap::insert`].
+//!
+//! - The return type of all dispatchable functions is [`frame::prelude::DispatchResult`]:
+#![doc = docify::embed!("../../substrate/frame/support/src/dispatch.rs", DispatchResult)]
+//!
+//! Which is more or less a normal Rust `Result`, with a custom [`frame::prelude::DispatchError`] as
+//! the `Err` variant. We won't cover this error in detail here, but importantly you should know
+//! that there is an `impl From<&'static string> for DispatchError` provided (see
+//! [here](`frame::prelude::DispatchError#impl-From<%26'static+str>-for-DispatchError`)). Therefore,
+//! we can use basic string literals as our error type and `.into()` them into `DispatchError`.
+//!
+//! - Why are all `get` and `mutate` functions returning an `Option`? This is the default behavior
+//!   of FRAME storage APIs. You can learn more about how to override this by looking into
+//!   [`frame::pallet_macros::storage`], and
+//!   [`frame::prelude::ValueQuery`]/[`frame::prelude::OptionQuery`]
+//!
+//! ### Improving Errors
+//!
+//! How we handle error in the above snippets is fairly rudimentary. Let's look at how this can be
+//! improved. First, we can use [`frame::prelude::ensure`] to express the error slightly better.
+//! This macro will call `.into()` under the hood.
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", transfer_better)]
+//!
+//! Moreover, you will learn in the [Safe Defensive Programming
+//! section](crate::reference_docs::safe_defensive_programming) that it is always recommended to use
+//! safe arithmetic operations in your runtime. By using [`frame::traits::CheckedSub`], we can not
+//! only take a step in that direction, but also improve the error handing and make it slightly more
+//! ergonomic.
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", transfer_better_checked)]
+//!
+//! This is more or less all the logic that there is this basic currency pallet!
+//!
+//! ### Your First (Test) Runtime
+//!
+//! Next, we create a "test runtime" in order to test our pallet. Recall from
+//! [`crate::polkadot_sdk::frame_runtime`] that a runtime is a collection of pallets, expressed
+//! through [`frame::runtime::prelude::construct_runtime`]. All runtimes also have to include
+//! [`frame::prelude::frame_system`]. So we expect to see a runtime with two pallet, `frame_system`
+//! and the one we just wrote.
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", runtime)]
+//!
+//! > [`frame::pallet_macros::derive_impl`] is a FRAME feature that enables developers to have
+//! > defaults for associated types.
+//!
+//! Recall that within our pallet, (almost) all blocks of code are generic over `<T: Config>`. And,
+//! because `trait Config: frame_system::Config`, we can get access to all items in `Config` (or
+//! `frame_system::Config`) using `T::NameOfItem`. This is all within the boundaries of how Rust
+//! traits and generics work. If unfamiliar with this pattern, read
+//! [`crate::reference_docs::trait_based_programming`] before going further.
+//!
+//! Crucially, a typical FRAME runtime contains a `struct Runtime`. The main role of this `struct`
+//! is to implement the `trait Config` of all pallets. That is, anywhere within your pallet code
+//! where you see `<T: Config>` (read: *"some type `T` that implements `Config`"*), in the runtime,
+//! it can be replaced with `<Runtime>`, because `Runtime` implements `Config` of all pallets, as we
+//! see above.
+//!
+//! Another way to think about this is that within a pallet, a lot of types are "unknown" and, we
+//! only know that they will be provided at some later point. For example, when you write
+//! `T::AccountId` (which is short for `<T as frame_system::Config>::AccountId`) in your pallet,
+//! you are in fact saying "*Some type `AccountId` that will be known later*". That "later" is in
+//! fact when you specify these types when you implement all `Config` traits for `Runtime`.
+//!
+//! As you see above, `frame_system::Config` is setting the `AccountId` to `u64`. Of course, a real
+//! runtime will not use this type, and instead reside to a proper type like a 32-byte standard
+//! public key. This is a HUGE benefit that FRAME developers can tap into: through the framework
+//! being so generic, different types can always be customized to simple things when needed.
+//!
+//! > Imagine how hard it would have been if all tests had to use a real 32-byte account id, as
+//! > opposed to just a u64 number 🙈.
+//!
+//! ### Your First Test
+//!
+//! The above is all you need to execute the dispatchables of your pallet. The last thing you need
+//! to learn is that all of your pallet testing code should be wrapped in
+//! [`frame::testing_prelude::TestState`]. This is a type that provides access to an in-memory state
+//! to be used in our tests.
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", first_test)]
+//!
+//! In the first test, we simply assert that there is no total issuance, and no balance associated
+//! with account `1`. Then, we mint some balance into `1`, and re-check.
+//!
+//! As noted above, the `T::AccountId` is now `u64`. Moreover, `Runtime` is replacing `<T: Config>`.
+//! This is why for example you see `Balances::<Runtime>::get(..)`. Finally, notice that the
+//! dispatchables are simply functions that can be called on top of the `Pallet` struct.
+//!
+//! TODO: hard to explain exactly `RuntimeOrigin::signed(1)` at this point.
+//!
+//! Congratulations! You have written your first pallet and tested it! Next, we learn a few optional
+//! steps to improve our pallet.
+//!
+//! ## Improving the Currency Pallet
+//!
+//! ### Better Test Setup
+//!
+//! Idiomatic FRAME pallets often use Builder pattern to define their initial state.
+//!
+//! > The Polkadot Blockchain Academy's Rust entrance exam has a
+//! > [section](https://github.com/Polkadot-Blockchain-Academy/pba-qualifier-exam/blob/main/src/m_builder.rs)
+//! > on this that you can use to learn the Builder Pattern.
+//!
+//! Let's see how we can implement a better test setup using this pattern. First, we define a
+//! `struct StateBuilder`.
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", StateBuilder)]
+//!
+//! This struct is meant to contain the same list of accounts and balances that we want to have at
+//! the beginning of each block. We hardcoded this to `let accounts = vec![(1, 100), (2, 100)];` so
+//! far. Then, if desired, we attach a default value for this struct.
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", default_state_builder)]
+//!
+//! Like any other builder pattern, we attach functions to the type to mutate its internal
+//! properties.
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", impl_state_builder_add)]
+//!
+//!  Finally --the useful part-- we write our own custom `build_and_execute` function on
+//! this type. This function will do multiple things:
+//!
+//! 1. It would consume `self` to produce our `TestState` based on the properties that we attached
+//!    to `self`.
+//! 2. It would execute any test function that we pass in as closure.
+//! 3. A nifty trick, this allows our test setup to have some code that is executed both before and
+//!    after each test. For example, in this test, we do some additional checking about the
+//!    correctness of the `TotalIssuance`. We leave it up to you as an exercise to learn why the
+//!    assertion should always hold, and how it is checked.
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", impl_state_builder_build)]
+//!
+//! We can write tests that specifically check the initial state, and making sure our `StateBuilder`
+//! is working exactly as intended.
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", state_builder_works)]
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", state_builder_add_balance)]
+//!
+//! ### More Tests
+//!
+//! Now that we have a more ergonomic test setup, let's see how a well written test for transfer and
+//! mint would look like.
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", transfer_works)]
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", mint_works)]
+//!
+//! It is always a good idea to build a mental model where you write *at least* one test for each
+//! "success path" of a dispatchable, and one test for each "failure path", such as:
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", transfer_from_non_existent_fails)]
+//!
+//! We leave it up to you to write a test that triggers to `InsufficientBalance` error.
+//!
+//! ### Event and Error
+//!
+//! Our pallet is mainly missing two parts that are common in most FRAME pallets: Events, and
+//! Errors. First, let's understand what each is.
+//!
+//! - **Error**: The static string-based error scheme we used so far is good for readability, but it
+//!   has a few drawbacks. These string literals will bloat the final wasm blob, and are relatively
+//!   heavy to transmit and encode/decode. Moreover, it is easy to mistype them by one character.
+//!   FRAME errors are exactly a solution to maintain readability, whilst fixing the drawbacks
+//!   mentioned. In short, we use an enum to represent different variants of our error. These
+//!   variants are then mapped in an efficient way (using only `u8` indices) to
+//!   [`sp_runtime::DispatchError::Module`] Read more about this in [`frame::pallet_macros::error`].
+//!
+//! - **Event**: Events are akin to the return type of dispatchables. They should represent what
+//!   happened at the end of a dispatch operation. Therefore, the convention is to use passive tense
+//!   for event names (eg. `SomethingHappened`). This allows other sub-systems or external parties
+//!   (eg. a light-node, a DApp) to listen to particular events happening, without needing to
+//!   re-execute the whole state transition function.
+//!
+//! TODO: both need to be improved a lot at the pallet-macro rust-doc level. Also my explanation
+//! of event is probably not the best.
+//!
+//! With the explanation out of the way, let's see how these components can be added. Both follow a
+//! fairly familiar syntax: normal Rust enums, with an extra `#[frame::event/error]` attribute
+//! attached.
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", Event)]
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", Error)]
+//!
+//! One slightly custom part of this is the `#[pallet::generate_deposit(pub(super) fn
+//! deposit_event)]` part. Without going into too much detail, in order for a pallet to emit events
+//! to the rest of the system, it needs to do two things:
+//!
+//! 1. Declare a type in its `Config` that refers to the overarching event type of the runtime. In
+//! short, by doing this, the pallet is expressing an important bound: `type RuntimeEvent:
+//! From<Event<Self>>`. Read: a `RuntimeEvent` exists, and it can be created from the local `enum
+//! Event` of this pallet. This enables the pallet to convert its `Event` into `RuntimeEvent`, and
+//! store it where needed.
+//!
+//! 2. But, doing this conversion and storing is too much to expect each pallet to define. FRAME
+//! provides a default way of storing events, and this is what `pallet::generate_deposit` is doing.
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", config_v2)]
+//!
+//! > These `Runtime*` types are better explained in
+//! > [`crate::reference_docs::frame_composite_enums`].
+//!
+//! Then, we can rewrite the `transfer` dispatchable as such:
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", transfer_v2)]
+//!
+//! Then, notice how now we would need to provide this `type RuntimeEvent` in our test runtime
+//! setup.
+#![doc = docify::embed!("./src/guides/your_first_pallet/mod.rs", runtime_v2)]
+//!
+//! In this snippet, the actual `RuntimeEvent` type (right hand side of `type RuntimeEvent =
+//! RuntimeEvent`) is generated by `construct_runtime`. An interesting way to inspect this type is
+//! to see its definition in rust-docs:
+//! [`crate::guides::your_first_pallet::pallet_v2::tests::runtime_v2::RuntimeEvent`].
+//!
+//!
+//!
+//! ## What Next?
+//!
+//! The following topics where used in this guide, but not covered in depth. It is suggested to
+//! study them subsequently:
+//!
+//! - [`crate::reference_docs::safe_defensive_programming`].
+//! - [`crate::reference_docs::frame_origin`].
+//! - [`crate::reference_docs::frame_composite_enums`].
+//! - The pallet we wrote in this guide was using `dev_mode`, learn more in
+//!   [`frame::pallet_macros::config`].
+//! - Learn more about the individual pallet items/macros, such as event and errors and call, in
+//!   [`frame::pallet_macros`].

+//! The Polkadot SDK Developer Documentation.
+//!
+//! This crate is a *minimal*, but *always-accurate* source of information for those wishing to

+//!
+//! > **Work in Progress**: This crate is under heavy development. Expect content to be moved and

+//!
+//! ## Getting Started
+//!
+//! We suggest the following reading sequence:
+//!
+//! - Start by learning about the the [`polkadot_sdk`], its structure and context.
+//! - Then, head over the [`guides`]. This modules contains in-depth guides about the most important
+//!   user-journeys of the Polkadot SDK.
+//! - Whilst reading the guides, you might find back-links to [`crate::reference_docs`].
+//! - Finally, <https://paritytech.github.io> is the parent website of this crate that contains the
+//!   list of further tools related to the Polkadot SDK.

+//! # Contribution
+//!
+//! The following sections cover more detailed information about this crate and how it should be
+//! maintained.
+//!
+//! ## Why Rust Docs?
+//!
+//! We acknowledge that blockchain based systems, particularly a cutting-edge one like Polkadot SDK
+//! is a software artifact that is complex, and rapidly evolving. This makes the task of documenting
+//! it externally extremely difficult, especially with regards to making sure it is up-to-date.
+//!
+//! Consequently, we argue that the best hedge against this is to move as much of the documentation
+//! near the source code as possible. This would further incentivize developers to keep the
+//! documentation up-to-date, as the overhead is reduced by making sure everything is in one
+//! repository, and everything being in `.rs` files.
+//!
+//! > This is not say that a more visually appealing version of this crate (for example as an
+//! > `md-book`) cannot exist, but it would be outside the scope of this crate.
+//!
+//! Moreover, we acknowledge that a major pain point has been not only outdated *concepts*, but also
+//! *outdated code*. For this, we commit to making sure no code-snippet in this crate is left as
+//! `///ignore` or `///no_compile`, making sure all code snippets are self-contained, compile-able,
+//! and correct at every single revision of the entire repository.
+//!
+//! > This also allows us to have a clear versioning on the entire content of this crate. For every
+//! commit of the Polkadot SDK, there would be one version of this crate that is guaranteed to be
+//! correct.
+//!
+//! > To achieve this, we often use [`docify`](https://github.com/sam0x17/docify), a nifty invention
+//! > of `@sam0x17`.
+//!
+//! Also see: <https://github.com/paritytech/polkadot-sdk/issues/991>.
+//!
+//! ## Scope
+//!
+//! The above would NOT be attainable if we don't acknowledge that the scope of this crate MUST be
+//! limited, or else its maintenance burden would be infeasible or not worthwhile. In short, future
+//! maintainers should always strive to keep the content of this repository as minimal as possible.
+//! Some of the following principles are specifically there to be the guidance for this.
+//!
+//! ## Principles
+//!
+//! The following guidelines are meant to be the guiding torch of those who contribute to this
+//! crate.
+//!
+//! 1. 🔺 Ground Up: Information should be layed out in the most ground-up fashion. The lowest level
+//!    (i.e. "ground") is Rust-docs. The highest level (i.e. "up") is "outside of this crate". In
+//!    between lies [`reference_docs`] and [`guides`], from low to high. The point of this principle
+//!    is to document as much of the information as possible in the lower level media, as it is
+//!    easier to maintain and more reachable. Then, use excessive linking to back-link when writing
+//!    in a more high level.
+//!
+//! > A prime example of this, the details of the FRAME storage APIs should NOT be explained in a
+//! > high level tutorial. They should be explained in the rust-doc of the corresponding type or
+//! > macro.
+//!
+//! 2. 🧘 Less is More: For reasons mentioned [above](#crate::why-rust-docs), the more concise this
+//!    crate is, the better.
+//! 3. √ Don’t Repeat Yourself – DRY: A summary of the above two points. Authors should always
+//!    strive to avoid any duplicate information. Every concept should ideally be documented in
+//!    *ONE* place and one place only. This makes the task of maintaining topics significantly
+//!    easier.
+//!
+//! > A prime example of this, the list of CLI arguments of a particular binary should not be
+//! > documented in multiple places across this crate. It should be only be documented in the
+//! > corresponding crate (e.g. `sc_cli`).
+//!
+//! > Moreover, this means that as a contributor, **it is your responsibility to have a grasp over
+//! > what topics are already covered in this crate, and how you can build on top of the information
+//! > that they already pose, rather than repeating yourself**.
+//!
+//! For more details about documenting guidelines, see:
+//! <https://github.com/paritytech/polkadot-sdk/master/docs/contributor/DOCUMENTATION_GUIDELINES.md>
+//!
+//! #### Example: Explaining `#[pallet::call]`
+//!
+//! <details>
+//! <summary>
+//! Let's consider the seemingly simple example of explaining to someone dead-simple code of a FRAME
+//! call and see how we can use the above principles.
+//! </summary>
+//!
+//!
+//! ```
+//! #[frame::pallet(dev_mode)]
+//! pub mod pallet {
+//! #   use frame::prelude::*;
+//! #   #[pallet::config]
+//! #   pub trait Config: frame_system::Config {}
+//! #   #[pallet::pallet]
+//! #   pub struct Pallet<T>(_);
+//!     #[pallet::call]
+//!     impl<T: Config> Pallet<T> {
+//!         pub fn a_simple_call(origin: OriginFor<T>, data: u32) -> DispatchResult {
+//!             ensure!(data > 10, "SomeStaticString");
+//!             todo!();
+//!         }
+//!     }
+//! }
+//! ```
+//!
+//! * Before even getting started, what is with all of this `<T: Config>`? We link to
+//! [`crate::reference_docs::trait_based_programming`].
+//! * First, the name. Why is this called `pallet::call`? This goes back to `enum Call`, which is
+//! explained in [`crate::reference_docs::frame_composite_enums`]. Build on top of this!
+//! * Then, what is `origin`? Just an account id? [`crate::reference_docs::frame_origin`].
+//! * Then, what is `DispatchResult`? Why is this called *dispatch*? Probably something that can be
+//! explained in the documentation of [`frame::prelude::DispatchResult`].
+//! * Why is `"SomeStaticString"` a valid error? Because there is implementation for it that you can
+//!   see [here](frame::prelude::DispatchError#impl-From<%26'static+str>-for-DispatchError).
+//!
+//!
+//! All of these are examples of underlying information that a contributor should:
+//!
+//! 1. Try and create and they are going along.
+//! 2. Back-link to if they already exist.
+//!
+//! Of course, all of this is not set in stone as a either/or rule. Sometimes, it is necessary to
+//! rephrase a concept in a new context.
+//!
+//! </details>
+//!
+//! ## `docs.substrate.io`
+//!
+//! This crate is meant to gradually replace `docs.substrate.io`. As any content is added here, the
+//! corresponding counter-part should be marked as deprecated, as described
+//! [here](https://github.com/paritytech/polkadot-sdk-docs/issues/26).
+//!
+//! ## `crates.io` and Publishing
+//!
+//! As it stands now, this crate cannot be published to crates.io because of its use of
+//! [workspace-level `docify`](https://github.com/sam0x17/docify/issues/22). For now, we accept this
+//! compromise, but in the long term, we should work towards finding a way to maintain different
+//! revisions of this crate.
+//!
+//! ## How to Build
+//!
+//! To build this crate properly, with with right HTML headers injected, run:
+//!
+//! ```no_compile
+//! RUSTDOCFLAGS="--html-in-header $(pwd)/docs/sdk/headers/toc.html" cargo doc -p polkadot-sdk-docs
+//! ```
+//!
+//! adding `--no-deps` would speed up the process while development. If even faster build time for
+//! docs is needed, you can temporarily remove most of the substrate/cumulus dependencies that are
+//! only used for linking purposes.

+//! # Cumulus
+//!
+//! Substrate provides a framework ([FRAME]) through which a blockchain node and runtime can easily

+//! A Cumulus-based runtime is fairly similar to other [FRAME]-based runtimes. Most notably, the
+//! following changes are applied to a normal FRAME-based runtime to make it a Cumulus-based
+//! runtime:
+//!
+//! #### Cumulus Pallets
+//!
+//! A parachain runtime should use a number of pallets that are provided by Cumulus and Substrate.
+//! Notably:
+//!
+//! - [`frame-system`](frame::prelude::frame_system), like all FRAME-based runtimes.
+//! - [`cumulus_pallet_parachain_system`]
+//! - [`parachain_info`]
+#![doc = docify::embed!("./src/polkadot_sdk/cumulus.rs", system_pallets)]
+//!
+//! Given that all Cumulus-based runtimes use a simple Aura-based consensus mechanism, the following
+//! pallets also need to be added:
+//!
+//! - [`pallet_timestamp`]
+//! - [`pallet_aura`]
+//! - [`cumulus_pallet_aura_ext`]
+#![doc = docify::embed!("./src/polkadot_sdk/cumulus.rs", consensus_pallets)]
+//!
+//!
+//! Finally, a separate macro, similar to
+//! [`impl_runtime_api`](frame::runtime::prelude::impl_runtime_apis), which creates the default set
+//! of runtime APIs, will generate the parachain runtime's validation runtime API, also known as
+//! parachain validation function (PVF). Without this API, the relay chain is unable to validate
+//! blocks produced by our parachain.
+#![doc = docify::embed!("./src/polkadot_sdk/cumulus.rs", validate_block)]

+//! > **F**ramework for **R**untime **A**ggregation of **M**odularized **E**ntities: Substrate's
+//! > State Transition Function (Runtime) Framework.
+//!
+//! ## Introduction
+//!
+//! As described in [`crate::reference_docs::wasm_meta_protocol`], at a high-level Substrate-based
+//! blockchains are composed of two parts:
+//!
+//! 1. A *runtime* which represents the state transition function (i.e. "Business Logic") of a
+//! blockchain, and is encoded as a WASM blob.
+//! 2. A node whose primary purpose is to execute the given runtime.
+#![doc = simple_mermaid::mermaid!("../../../mermaid/substrate_simple.mmd")]
+//!
+//! *FRAME is the Substrate's framework of choice to build a runtime.*
+//!
+//! FRAME is composed of two major components, **pallets** and a **runtime**.
+//!
+//! ## Pallets
+//!
+//! A pallet is a unit of encapsulated logic. It has a clearly defined responsibility and can be
+//! linked to other pallets. In order to be reusable, pallets shipped with FRAME strive to only care
+//! about its own responsibilities and make as few assumptions about the general runtime as
+//! possible. A pallet is analogous to a _module_ in the runtime.
+//!
+//! A pallet is defined as a `mod pallet` wrapped by the [`frame::pallet`] macro. Within this macro,
+//! pallet components/parts can be defined. Most notable of these parts are:
+//!
+//! - [Config](frame::pallet_macros::config), allowing a pallet to make itself configurable and
+//!   generic over types, values and such.
+//! - [Storage](frame::pallet_macros::storage), allowing a pallet to define onchain storage.
+//! - [Dispatchable function](frame::pallet_macros::call), allowing a pallet to define extrinsics
+//!   that are callable by end users, from the outer world.
+//! - [Events](frame::pallet_macros::event), allowing a pallet to emit events.
+//! - [Errors](frame::pallet_macros::error), allowing a pallet to emit well-formed errors.
+//!
+//! Some of these pallet components resemble the building blocks of a smart contract. While both
+//! models are programming state transition functions of blockchains, there are crucial differences
+//! between the two. See [`crate::reference_docs::runtime_vs_smart_contract`] for more.
+//!
+//! Most of these components are defined using macros, the full list of which can be found in
+//! [`frame::pallet_macros`].
+//!
+//! ### Example
+//!
+//! The following examples showcases a minimal pallet.
+#![doc = docify::embed!("src/polkadot_sdk/frame_runtime.rs", pallet)]
+//!
+//!
+//! A runtime is a collection of pallets that are amalgamated together. Each pallet typically has
+//! some configurations (exposed as a `trait Config`) that needs to be *specified* in the runtime.
+//! This is done with [`frame::runtime::prelude::construct_runtime`].
+//!
+//! A (real) runtime that actually wishes to compile to WASM needs to also implement a set of
+//! runtime-apis. These implementation can be specified using the
+//! [`frame::runtime::prelude::impl_runtime_apis`] macro.
+//!
+//! ### Example
+//!
+//! The following example shows a (test) runtime that is composing the pallet demonstrated above,
+//! next to the [`frame::prelude::frame_system`] pallet, into a runtime.
+#![doc = docify::embed!("src/polkadot_sdk/frame_runtime.rs", runtime)]
+//!
+//! ## More Examples
+//!
+//! You can find more FRAME examples that revolve around specific features at [`pallet_examples`].
+//!
+//! ## Alternatives 🌈
+//!
+//! There is nothing in the Substrate's node side code-base that mandates the use of FRAME. While
+//! FRAME makes it very simple to write Substrate-based runtimes, it is by no means intended to be
+//! the only one. At the end of the day, any WASM blob that exposes the right set of runtime APIs is
+//! a valid Runtime form the point of view of a Substrate client (see
+//! [`crate::reference_docs::wasm_meta_protocol`]). Notable examples are:
+//!
+//! * writing a runtime in pure Rust, as done in [this template](https://github.com/JoshOrndorff/frameless-node-template).
+//! * writing a runtime in AssemblyScript,as explored in [this project](https://github.com/LimeChain/subsembly).

+//!
+//! ### Summary
+//!
+//! The following diagram summarizes how some of the components of Polkadot SDK work together:
+#![doc = simple_mermaid::mermaid!("../../../mermaid/polkadot_sdk_substrate.mmd")]
+//!
+//! A Substrate-based chain is a blockchain composed of a runtime and a node. As noted above, the
+//! runtime is the application logic of the blockchain, and the node is everything else.
+//! See [`crate::reference_docs::wasm_meta_protocol`] for an in-depth explanation of this. The
+//! former is built with [`frame`], and the latter is built with rest of Substrate.
+//!
+//! > You can think of a Substrate-based chain as a white-labeled blockchain.
+#![doc = simple_mermaid::mermaid!("../../../mermaid/polkadot_sdk_polkadot.mmd")]
+//! Polkadot is itself a Substrate-based chain, composed of the exact same two components. It has
+//! specialized logic in both the node and the runtime side, but it is not "special" in any way.
+//!
+//! A parachain is a "special" Substrate-based chain, whereby both the node and the runtime
+//! components have became "Polkadot-aware" using Cumulus.
+#![doc = simple_mermaid::mermaid!("../../../mermaid/polkadot_sdk_parachain.mmd")]

+//!
+//! ## Platform
+//!
+//! In this section, we examine what what platform Polkadot exactly provides to developers.
+//!
+//! ### Polkadot White Paper
+//!
+//! The original vision of Polkadot (everything in the whitepaper, which was eventually called
+//! **Polkadot 1.0**) revolves around the following arguments:
+//!
+//! * Future is multi-chain, because we need different chains with different specialization to
+//!   achieve widespread goals.
+//! * In other words, no single chain is good enough to achieve all goals.
+//! * A multi-chain future will inadvertently suffer from fragmentation of economic security.
+//!   * This stake fragmentation will make communication over consensus system with varying security
+//!     levels inherently unsafe.
+//!
+//! Polkadot's answer to the above is:
+//!
+//! > The chains of the future must have a way to share their economic security, whilst maintaining
+//! > their execution and governance sovereignty. These chains are called "Parachains".
+//!
+//! * Shared Security: The idea of shared economic security sits at the core of Polkadot. Polkadot
+//!   enables different parachains* to pool their economic security from Polkadot (i.e. "*Relay
+//!   Chain*").
+//! * (heterogenous) Sharded Execution: Yet, each parachain is free to have its own execution logic
+//!   (runtime), which also encompasses governance and sovereignty. Moreover, Polkadot ensures the
+//!   correct execution of all parachain, without having all of its validators re-execute all
+//!   parachain blocks. When seen from this perspective, the fact that Polkadot executes different
+//!   parachains means it is a platform that has fully delivered (the holy grail of) "Full Execution
+//!   Sharding". TODO: link to approval checking article. https://github.com/paritytech/polkadot-sdk-docs/issues/66
+//! * A framework to build blockchains: In order to materialize the ecosystem of parachains, an easy
+//!   blockchain framework must exist. This is [Substrate](crate::polkadot_sdk::substrate),
+//!   [FRAME](crate::polkadot_sdk::frame_runtime) and [Cumulus](crate::polkadot_sdk::cumulus).
+//! * A communication language between blockchains: In order for these blockchains to communicate,
+//!   they need a shared language. [XCM](crate::polkadot_sdk::xcm) is one such language, and the one
+//!   that is most endorsed in the Polkadot ecosystem.
+//!
+//! > Note that the interoperability promised by Polkadot is unparalleled in that any two parachains
+//! > connected to Polkadot have the same security and can have much better guarantees about the
+//! > security of the recipient of any message. TODO: weakest link in bridges systems. https://github.com/paritytech/polkadot-sdk-docs/issues/66
+//!
+//! Polkadot delivers the above vision, alongside a flexible means for parachains to schedule
+//! themselves with the Relay Chain. To achieve this, Polkadot has been developed with an
+//! architecture similar to that of a computer. Polkadot Relay Chain has a number of "cores". Each
+//! core is (in simple terms) capable of progressing 1 parachain at a time. For example, a parachain
+//! can schedule itself on a single core for 5 relay chain blocks.
+//!
+//! Within the scope of Polkadot 1.x, two main scheduling ways have been considered:
+//!
+//! * Long term Parachains, obtained through locking a sum of DOT in an auction system.
+//! * on-demand Parachains, purchased through paying DOT to the relay-chain whenever needed.
+//!
+//! ### The Future
+//!
+//! After delivering Polkadot 1.x, the future of Polkadot as a protocol and platform is in the hands
+//! of the community and the fellowship. This is happening most notable through the RFC process.
+//! Some of the RFCs that do alter Polkadot as a platform and have already passed are as follows:
+//!
+//! - RFC#1: [Agile-coretime](https://github.com/polkadot-fellows/RFCs/blob/main/text/0001-agile-coretime.md):
+//!   Agile periodic-sale-based model for assigning Coretime on the Polkadot Ubiquitous Computer.
+//! - RFC#5: [Coretime-interface](https://github.com/polkadot-fellows/RFCs/blob/main/text/0005-coretime-interface.md):
+//!   Interface for manipulating the usage of cores on the Polkadot Ubiquitous Computer.
+// TODO: add more context and explanations about Polkadot as the Ubiquitous Computer and related
+// tech. https://github.com/paritytech/polkadot-sdk-docs/issues/66

+//! # Substrate
+//!
+//! Substrate is a Rust framework for building blockchains in a modular and extensible way. While in
+//! itself un-opinionated, it is the main engine behind the Polkadot ecosystem.
+//!
+//! ## Overview, Philosophy
+//!
+//! Substrate approaches blockchain development with an acknowledgement of a few self-evident
+//! truths:
+//!
+//! 1. Society and technology evolves.
+//! 2. Humans are fallible.
+//!
+//! This, makes the task of designing a correct, safe and long-lasting blockchain system hard.
+//!
+//! Nonetheless, in strive towards achieve this goal, Substrate embraces the following:
+//!
+//! 1. Use of **Rust** as a modern and safe programming language, which limits human error through
+//!    various means, most notably memory and type safety.
+//! 2. Substrate is written from the ground-up with a *generic, modular and extensible* design. This
+//!    ensures that software components can be easily swapped and upgraded. Examples of this is
+//!    multiple consensus mechanisms provided by Substrate, as listed below.
+//! 3. Lastly, the final blockchain system created with the above properties needs to be
+//!    upgradeable. In order to achieve this, Substrate is designed as a meta-protocol, whereby the
+//!    application logic of the blockchain (called "Runtime") is encoded as a WASM blob, and is
+//!    stored in the state. The rest of the system (called "node") acts as the executor of the WASM
+//!    blob.
+//!
+//! In essence, the meta-protocol of all Substrate based chains is the "Runtime as WASM blob"
+//! accord. This enables the Runtime to become inherently upgradeable, crucially without forks. The
+//! upgrade is merely a matter of the WASM blob being changed in the state, which is, in principle,
+//! same as updating an account's balance. Learn more about this in detail in
+//! [`crate::reference_docs::wasm_meta_protocol`].
+//!
+//! > A great analogy for substrate is the following: Substrate node is a gaming console, and a WASM
+//! > runtime, possibly created with FRAME is the game being inserted into the console.
+//!
+//! [`frame`], Substrate's default runtime development library, takes the above safety practices
+//! even further by embracing a declarative programming model whereby correctness is enhanced and
+//! the system is highly configurable through parameterization. Learn more about this in
+//! [`crate::reference_docs::trait_based_programming`].
+//!
+//! ## How to Get Started
+//!
+//! Substrate offers different options at the spectrum of technical freedom <-> development ease.
+//!
+//! * The easiest way to use Substrate is to use one of the templates (some of which listed at
+//!   [`crate::polkadot_sdk::templates`]) and only tweak the parameters of the runtime or node. This
+//!   allows you to launch a blockchain in minutes, but is limited in technical freedom.
+//! * Next, most developers wish to develop their custom runtime modules, for which the de-facto way
+//! is [`frame`](crate::polkadot_sdk::frame_runtime).
+//! * Finally, Substrate is highly configurable at the node side as well, but this is the most
+//!   technically demanding.
+//!
+//! > A notable Substrate-based blockchain that has built both custom FRAME pallets and custom
+//! > node-side components is <https://github.com/Cardinal-Cryptography/aleph-node>.
+#![doc = simple_mermaid::mermaid!("../../../mermaid/substrate_dev.mmd")]
+//!
+//! ## Structure
+//!
+//! Substrate contains a large number of crates, therefore it is useful to have an overview of what
+//! they are, and how they are organized. In broad terms, these crates are divided into three
+//! categories:
+//!
+//! * `sc-*` (short for *Substrate-client*) crates, located under `./client` folder. These are all
+//!   the crates that lead to the node software. Notable examples [`sc_network`], various consensus
+//!   crates, RPC ([`sc_rpc_api`]) and database ([`sc_client_db`]), all of which are expected to
+//!   reside in the node side.
+//! * `sp-*` (short for *substrate-primitives*) crates, located under `./primitives` folder. These
+//!   are crates that facilitate both the node and the runtime, but are not opinionated about what
+//!   framework is using for building the runtime. Notable examples are [`sp_api`] and [`sp_io`],
+//!   which form the communication bridge between the node and runtime.
+//! * `pallet-*` and `frame-*` crates, located under `./frame` folder. These are the crates related
+//!   to FRAME. See [`frame`] for more information.
+//!
+//! ### WASM Build
+//!
+//! Many of the Substrate crates, such as entire `sp-*`, need to compile to both WASM (when a WASM
+//! runtime is being generated) and native (for example, when testing). To achieve this, Substrate
+//! follows the convention of the Rust community, and uses a `feature = "std"` to signify that a
+//!  crate is being built with the standard library, and is built for native. Otherwise, it is built
+//!  for `no_std`.
+//!
+//! This can be summarized in `#![cfg_attr(not(feature = "std"), no_std)]`, which you can often find
+//! in any Substrate-based runtime.
+//!
+//! Substrate-based runtimes use [`substrate_wasm_builder`] in their `build.rs` to automatically
+//! build their WASM files as a part of normal build command (e.g. `cargo build`). Once built, the
+//! wasm file is placed in `./target/{debug|release}/wbuild/{runtime_name}.wasm`.
+//!
+//! ### Binaries
+//!
+//! Multiple binaries are shipped with substrate, the most important of which are located in the
+//! [`./bin`](https://github.com/paritytech/polkadot-sdk/tree/master/substrate/bin) folder.
+//!
+//! * [`node_cli`] is an extensive substrate node that contains the superset of all runtime and node
+//!   side features. The corresponding runtime, called [`kitchensink_runtime`] contains all of the
+//!   modules that are provided with `FRAME`. This node and runtime is only used for testing and
+//!   demonstration.
+//!     * [`chain_spec_builder`]: Utility to build more detailed chain-specs for the aforementioned
+//!       node. Other projects typically contain a `build-spec` subcommand that does the same.
+//! * [`node_template`](https://github.com/paritytech/polkadot-sdk/tree/master/substrate/bin/node-template):
+//!   a template node that contains a minimal set of features and can act as a starting point of a
+//!   project.
+//! * [`subkey`]: Substrate's key management utility.
+//!
+//! ### Anatomy of a Binary Crate
+//!
+//! From the above, [`node_cli`]/[`kitchensink_runtime`] and `node-template` are essentially
+//! blueprints of a Substrate-based project, as the name of the latter is implying. Each
+//! Substrate-based project typically contains the following:
+//!
+//! * Under `./runtime`, a `./runtime/src/lib.rs` which is the top level runtime amalgamator file.
+//!   This file typically contains the [`frame::runtime::prelude::construct_runtime`] and
+//!   [`frame::runtime::prelude::impl_runtime_apis`] macro calls, which is the final definition of a
+//!   runtime.
+//!
+//! * Under `./node`, a `main.rs`, which is the starting point, and a `./service.rs`, which contains
+//!   all the node side components. Skimming this file yields an overview of the networking,
+//!   database, consensus and similar node side components.
+//!
+//! > The above two are conventions, not rules.
+//!
+//! > See <https://github.com/paritytech/polkadot-sdk/issues/5> for an update on how the node side
+//! > components are being amalgamated.
+//!
+//! ## Parachain?
+//!
+//! As noted above, Substrate is the main engine behind the Polkadot ecosystem. One of the ways
+//! through which Polkadot can be utilized is by building "parachains", blockchains that are
+//! connected to Polkadot's shared security.
+//!
+//! To build a parachain, one could use [Cumulus](crate::polkadot_sdk::cumulus), the library on
+//! top of Substrate, empowering any substrate-based chain to be a Polkadot parachain.
+//!
+//! ## Where To Go Next?
+//!
+//! Additional noteworthy crates within substrate:
+//!
+//! - RPC APIs of a Substrate node: [`sc_rpc_api`]/[`sc_rpc`]
+//! - CLI Options of a Substrate node: [`sc_cli`]
+//! - All of the consensus related crates provided by Substrate:
+//!     - [`sc_consensus_aura`]
+//!     - [`sc_consensus_babe`]
+//!     - [`sc_consensus_grandpa`]
+//!     - [`sc_consensus_beefy`] (TODO: @adrian, add some high level docs https://github.com/paritytech/polkadot-sdk-docs/issues/57)
+//!     - [`sc_consensus_manual_seal`]
+//!     - [`sc_consensus_pow`]

+//! # Templates
+//!
+//! ### Internal
+//!
+//! The following templates are maintained as a part of the `polkadot-sdk` repository:
+//!
+//! - classic [`substrate-node-template`]: is a white-labeled substrate-based blockchain with a
+//!   moderate amount of features. It can act as a great starting point for those who want to learn
+//!   Substrate/FRAME and want to have a template that is already doing something.
+//! - [`substrate-minimal-template`]: Same as the above, but it contains the least amount of code in
+//!   both the node and runtime. It is a great starting point for those who want to deeply learn
+//!   Substrate and FRAME.
+//! - classic [`cumulus-parachain-template`], which is the de-facto parachain template shipped with
+//!   Cumulus. It is the parachain-enabled version of [`substrate-node-template`].
+//!
+//! ### External Templates
+//!
+//! Noteworthy templates outside of this repository.
+//!
+//! - [`extended-parachain-template`](https://github.com/paritytech/extended-parachain-template): A
+//!   parachain template that contains more built-in functionality such as assets and NFTs.
+//! - [`frontier-parachain-template`](https://github.com/paritytech/frontier-parachain-template): A
+//!   parachain template for launching EVM-compatible parachains.
+//!
+//! [`substrate-node-template`]: https://github.com/paritytech/polkadot-sdk/blob/master/substrate/bin/node-template/
+//! [`substrate-minimal-template`]: https://github.com/paritytech/polkadot-sdk/blob/master/substrate/bin/minimal/
+//! [`cumulus-parachain-template`]: https://github.com/paritytech/polkadot-sdk/blob/master/cumulus/parachain-template/
+
+// TODO: in general, we need to make a deliberate choice here of moving a few key templates to this
+// repo (nothing stays in `substrate-developer-hub`) and the everything else should be community
+// maintained. https://github.com/paritytech/polkadot-sdk-docs/issues/67
+
+// TODO: we should rename `substrate-node-template` to `substrate-basic-template`,

+
+// NOTE: a super important detail that I am looking forward to here is
+// <https://github.com/paritytech/polkadot-sdk/issues/62#issuecomment-1691523754> and
+// <https://github.com/paritytech/polkadot-sdk/issues/5>. Meaning that I would not spend time on

+// am sure we will either have a better "node-builder" code that can actually be tested, or an
+// "omni-node" that can run (almost) any wasm file. We should already build tutorials in this
+// direction IMO. This also affects all the templates. If we have a good neat runtime file, which we
+// are moving toward, and a good node-builder, we don't need all of these damn templates. These
+// templates are only there because the boilerplate is super horrible atm.

+//! # State Transition Function
+//!
+//! This document briefly explains how in the context of Substrate-based blockchains, we view the
+//! blockchain as a **decentralized state transition function**.
+//!
+//! Recall that a blockchain's main purpose is to help a permissionless set of entities to agree on
+//! a shared data-set, and how it evolves. This is called the **State**, also referred to as
+//! "onchain" data, or *Storage* in the context of FRAME. The state is where the account balance of
+//! each user is, for example, stored, and there is a canonical version of it that everyone agrees
+//! upon.
+//!
+//! Then, recall that a typical blockchain system will alter its state through execution of blocks.
+//! *The component that dictates how this state alteration can happen is called the state transition
+//! function*.
+#![doc = simple_mermaid::mermaid!("../../../mermaid/stf_simple.mmd")]
+//!
+//! In Substrate-based blockchains, the state transition function is called the *Runtime*. This is
+//! explained further in [`crate::reference_docs::wasm_meta_protocol`].
+//!
+//! With this in mind, we can paint a complete picture of a blockchain as a state machine:
+#![doc = simple_mermaid::mermaid!("../../../mermaid/stf.mmd")]
+//!
+//! In essence, the state of the blockchain at block N is the outcome of applying the state
+//! transition function to the the previous state, and the current block as input. This can be
+//! mathematically represented as:
+//!
+//! ```math
+//! STF = F(State_N, Block_N) -> State_{N+1}

+//! # Constructing and Signing Extrinsics
+//!
+//! Extrinsics are payloads that are stored in blocks which are responsible for altering the state
+//! of a blockchain via the [_state transition
+//! function_][crate::reference_docs::blockchain_state_machines].
+//!
+//! Substrate is configurable enough that extrinsics can take any format. In practice, runtimes
+//! tend to use our [`sp_runtime::generic::UncheckedExtrinsic`] type to represent extrinsics,
+//! because it's generic enough to cater for most (if not all) use cases. In Polkadot, this is
+//! configured [here](https://github.com/polkadot-fellows/runtimes/blob/94b2798b69ba6779764e20a50f056e48db78ebef/relay/polkadot/src/lib.rs#L1478)
+//! at the time of writing.
+//!
+//! What follows is a description of how extrinsics based on this
+//! [`sp_runtime::generic::UncheckedExtrinsic`] type are encoded into bytes. Specifically, we are
+//! looking at how extrinsics with a format version of 4 are encoded. This version is itself a part
+//! of the payload, and if it changes, it indicates that something about the encoding may have
+//! changed.
+//!
+//! # Encoding an Extrinsic
+//!
+//! At a high level, all extrinsics compatible with [`sp_runtime::generic::UncheckedExtrinsic`]
+//! are formed from concatenating some details together, as in the following pseudo-code:
+//!
+//! ```text
+//! extrinsic_bytes = concat(
+//!     compact_encoded_length,
+//!     version_and_maybe_signature,
+//!     call_data
+//! )
+//! ```
+//!
+//! For clarity, the actual implementation in Substrate looks like this:
+#![doc = docify::embed!("../../substrate/primitives/runtime/src/generic/unchecked_extrinsic.rs", unchecked_extrinsic_encode_impl)]
+//!
+//! Let's look at how each of these details is constructed:
+//!
+//! ## compact_encoded_length
+//!
+//! This is a [SCALE compact encoded][frame::deps::codec::Compact] integer which is equal to the
+//! length, in bytes, of the rest of the extrinsic details.
+//!
+//! To obtain this value, we must encode and concatenate together the rest of the extrinsic details
+//! first, and then obtain the byte length of these. We can then compact encode that length, and
+//! prepend it to the rest of the details.
+//!
+//! ## version_and_maybe_signature
+//!
+//! If the extrinsic is _unsigned_, then `version_and_maybe_signature` will be just one byte
+//! denoting the _transaction protocol version_, which is 4 (or `0b0000_0100`).
+//!
+//! If the extrinsic is _signed_ (all extrinsics submitted from users must be signed), then
+//! `version_and_maybe_signature` is obtained by concatenating some details together, ie:
+//!
+//! ```text
+//! version_and_maybe_signature = concat(
+//!     version_and_signed,
+//!     from_address,
+//!     signature,
+//!     signed_extensions_extra,
+//! )
+//! ```
+//!
+//! Each of the details to be concatenated together is explained below:
+//!
+//! ### version_and_signed
+//!
+//! This is one byte, equal to `0x84` or `0b1000_0100` (i.e. an upper 1 bit to denote that it is
+//! signed, and then the transaction version, 4, in the lower bits).
+//!
+//! ### from_address
+//!
+//! This is the [SCALE encoded][frame::deps::codec] address of the sender of the extrinsic. The
+//! address is the first generic parameter of [`sp_runtime::generic::UncheckedExtrinsic`], and so
+//! can vary from chain to chain.
+//!
+//! The address type used on the Polkadot relay chain is [`sp_runtime::MultiAddress<AccountId32>`],
+//! where `AccountId32` is defined [here][`sp_core::crypto::AccountId32`]. When constructing a
+//! signed extrinsic to be submitted to a Polkadot node, you'll always use the
+//! [`sp_runtime::MultiAddress::Id`] variant to wrap your `AccountId32`.
+//!
+//! ### signature
+//!
+//! This is the [SCALE encoded][frame::deps::codec] signature. The signature type is configured via
+//! the third generic parameter of [`sp_runtime::generic::UncheckedExtrinsic`], which determines the
+//! shape of the signature and signing algorithm that should be used.
+//!
+//! The signature is obtained by signing the _signed payload_ bytes (see below on how this is
+//! constructed) using the private key associated with the address and correct algorithm.
+//!
+//! The signature type used on the Polkadot relay chain is [`sp_runtime::MultiSignature`]; the
+//! variants there are the types of signature that can be provided.
+//!
+//! ### signed_extensions_extra
+//!
+//! This is the concatenation of the [SCALE encoded][frame::deps::codec] bytes representing each of
+//! the [_signed extensions_][sp_runtime::traits::SignedExtension], and are configured by the
+//! fourth generic parameter of [`sp_runtime::generic::UncheckedExtrinsic`]. Learn more about
+//! signed extensions [here][crate::reference_docs::signed_extensions].
+//!
+//! When it comes to constructing an extrinsic, each signed extension has two things that we are
+//! interested in here:
+//!
+//! - The actual SCALE encoding of the signed extension type itself; this is what will form our
+//!   `signed_extensions_extra` bytes.
+//! - An `AdditionalSigned` type. This is SCALE encoded into the `signed_extensions_additional` data
+//!   of the _signed payload_ (see below).
+//!
+//! Either (or both) of these can encode to zero bytes.
+//!
+//! Each chain configures the set of signed extensions that it uses in its runtime configuration.
+//! At the time of writing, Polkadot configures them
+//! [here](https://github.com/polkadot-fellows/runtimes/blob/1dc04eb954eadf8aadb5d83990b89662dbb5a074/relay/polkadot/src/lib.rs#L1432C25-L1432C25).
+//! Some of the common signed extensions are defined
+//! [here][frame::deps::frame_system#signed-extensions].
+//!
+//! Information about exactly which signed extensions are present on a chain and in what order is
+//! also a part of the metadata for the chain. For V15 metadata, it can be
+//! [found here][frame::deps::frame_support::__private::metadata::v15::ExtrinsicMetadata].
+//!
+//! ## call_data
+//!
+//! This is the main payload of the extrinsic, which is used to determine how the chain's state is
+//! altered. This is defined by the second generic parameter of
+//! [`sp_runtime::generic::UncheckedExtrinsic`].
+//!
+//! A call can be anything that implements [`Encode`][frame::deps::codec::Encode]. In FRAME-based
+//! runtimes, a call is represented as an enum of enums, where the outer enum represents the FRAME
+//! pallet being called, and the inner enum represents the call being made within that pallet, and
+//! any arguments to it. Read more about the call enum
+//! [here][crate::reference_docs::frame_composite_enums].
+//!
+//! FRAME `Call` enums are automatically generated, and end up looking something like this:
+#![doc = docify::embed!("./src/reference_docs/extrinsic_encoding.rs", call_data)]
+//!
+//! In pseudo-code, this `Call` enum encodes equivalently to:
+//!
+//! ```text
+//! call_data = concat(
+//!     pallet_index,
+//!     call_index,
+//!     call_args
+//! )
+//! ```
+//!
+//! - `pallet_index` is a single byte denoting the index of the pallet that we are calling into, and
+//!   is what the tag of the outermost enum will encode to.
+//! - `call_index` is a single byte denoting the index of the call that we are making the pallet,
+//!   and is what the tag of the inner enum will encode to.
+//! - `call_args` are the SCALE encoded bytes for each of the arguments that the call expects, and
+//!   are typically provided as values to the inner enum.
+//!
+//! Information about the pallets that exist for a chain (including their indexes), the calls
+//! available in each pallet (including their indexes), and the arguments required for each call
+//! can be found in the metadata for the chain. For V15 metadata, this information
+//! [is here][frame::deps::frame_support::__private::metadata::v15::PalletMetadata].
+//!
+//! # The Signed Payload Format
+//!
+//! All extrinsics submitted to a node from the outside world (also known as _transactions_) need to
+//! be _signed_. The data that needs to be signed for some extrinsic is called the _signed payload_,
+//! and its shape is described by the following pseudo-code:
+//!
+//! ```text
+//! signed_payload = concat(
+//!     call_data,
+//!     signed_extensions_extra,
+//!     signed_extensions_additional,
+//! )
+//!
+//! if length(signed_payload) > 256 {
+//!     signed_payload = blake2_256(signed_payload)
+//! }
+//! ```
+//!
+//! The bytes representing `call_data` and `signed_extensions_extra` can be obtained as descibed
+//! above. `signed_extensions_additional` is constructed by SCALE encoding the
+//! ["additional signed" data][sp_runtime::traits::SignedExtension::AdditionalSigned] for each
+//! signed extension that the chain is using, in order.
+//!
+//! Once we've concatenated those together, we hash the result if it's greater than 256 bytes in
+//! length using a Blake2 256bit hasher.
+//!
+//! The [`sp_runtime::generic::SignedPayload`] type takes care of assembling the correct payload
+//! for us, given `call_data` and a tuple of signed extensions.
+//!
+//! # Example Encoding
+//!
+//! Using [`sp_runtime::generic::UncheckedExtrinsic`], we can construct and encode an extrinsic
+//! as follows:
+#![doc = docify::embed!("./src/reference_docs/extrinsic_encoding.rs", encoding_example)]
+
+#[docify::export]

+	type Extrinsic =
+		UncheckedExtrinsic<MultiAddress<AccountId32, ()>, Call, MultiSignature, SignedExtensions>;
+
+	pub fn encode_demo_extrinsic() -> Vec<u8> {
+		// The "from" address will be our Alice dev account.

+			signed_extensions_example::AddToPayload(1),
+			signed_extensions_example::AddToSignaturePayload,
+		);
+
+		// Construct our call data:
+		let call_data = Call::PalletA(PalletACall::Foo("Hello".to_string()));
+
+		// The signed payload. This takes care of encoding the call_data,
+		// signed_extensions_extra and signed_extensions_additional, and hashing
+		// the result if it's > 256 bytes:
+		let signed_payload = SignedPayload::new(&call_data, signed_extensions.clone());
+
+		// Sign the signed payload with our Alice dev account's private key,
+		// and wrap the signature into the expected type:
+		let signature = {
+			let sig = Keyring::Alice.sign(&signed_payload.encode());
+			MultiSignature::Sr25519(sig)
+		};
+
+		// Now, we can build and encode our extrinsic:
+		let ext = Extrinsic::new_signed(call_data, from_address, signature, signed_extensions);
+
+		let encoded_ext = ext.encode();
+		encoded_ext
+	}

+//!
+//!
+//! Notes:

+//! - An extension of [`runtime_vs_smart_contract`], showcasing the tools needed to build a safe

+//! # Glossary
+//!
+//! #### State
+//!
+//! The data around which the blockchain network wishes to come to consensus. Also
+//! referred to as "onchain data", "onchain storage" or sometimes just "storage". In UTXO based
+//! blockchains, is referred to as "ledger".
+//!
+//! **Synonyms**: Onchain data, Onchain storage, Storage, Ledger
+//!
+//! #### State Transition Function
+//!
+//! The WASM Blob that dictates how the blockchain should transition its state upon encountering new
+//! blocks.
+//!
+//! #### Host
+//!
+//! The environment that hosts and executes the [state transition function's WASM
+//! blob](#state-transition-function).
+//!
+//! #### Node
+//!
+//! The full software artifact that contains the [host](#host), but importantly also all the other
+//! modules needed to be part of a blockchain network, such as peer-to-peer networking, database and
+//! such.
+//!
+//! **Synonyms**: Client
+//!
+//! #### Light Node
+//!
+//! Same as [node](#nodes), but when capable of following the network only through listening to
+//! block headers. Usually capable of running in more constrained environments, such as an embedded
+//! device, phone, or a web browser.
+//!
+//! **Synonyms**: Light Client
+//!
+//! #### Offchain
+//!
+//! Refers to operations conducted outside the blockchain's consensus mechanism. They are essential
+//! for enhancing scalability and efficiency, enabling activities like data fetching and computation
+//! without bloating the blockchain state.
+//!
+//! #### Host Functions:
+//!
+//! Host functions are the node's API, these are functions provided by the runtime environment (the
+//! [host](#host)) to the Wasm runtime. These functions allow the Wasm code to interact with and
+//! perform operations on the [node](#node), like accessing the blockchain state.
+//!
+//! #### Runtime API:
+//!
+//! This is the API of the runtime, it acts as a communication bridge between the runtime and the
+//! node, serving as the exposed interface that facilitates their interactions.
+//!
+//! #### Dispatchable:
+//!
+//! Dispatchables are [function objects](https://en.wikipedia.org/wiki/Function_object) that act as
+//! the entry points in [FRAME](frame) pallets. They can be called by internal or external entities
+//! to interact with the blockchain's state. They are a core aspect of the runtime logic, handling
+//! transactions and other state-changing operations.
+//!
+//! **Synonyms**: Callable
+//!
+//! #### Extrinsic
+//!
+//! An extrinsic is a general term for a piece of data that is originated outside of the runtime,
+//! included into a block and leads to some action. This includes user-initiated transactions as
+//! well as inherents which are placed into the block by the block-builder.
+//!
+//! #### Pallet
+//!
+//! Similar to software modules in traditional programming, [FRAME](frame) pallets in Substrate are
+//! modular components that encapsulate distinct functionalities or business logic. Just as
+//! libraries or modules are used to build and extend the capabilities of a software application,
+//! pallets are the foundational building blocks for constructing a blockchain's runtime with frame.
+//! They enable the creation of customizable and upgradeable networks, offering a composable
+//! framework for a Substrate-based blockchain. Each pallet can be thought of as a plug-and-play
+//! module, enhancing the blockchain's functionality in a cohesive and integrated manner.
+//!
+//! #### Full Node
+//!
+//! It is a node that prunes historical states, keeping only recent finalized block states to reduce
+//! storage needs. Full nodes provide current chain state access and allow direct submission and
+//! validation of extrinsics, maintaining network decentralization.
+//!
+//! #### Archive Node
+//!
+//! An archive node is a specialized node that maintains a complete history of all block states and
+//! transactions. Unlike a full node, it does not prune historical data, ensuring full access to the
+//! entire blockchain history. This makes it essential for detailed blockchain analysis and
+//! historical queries, but requires significantly more storage capacity.
+//!
+//! #### Validator
+//!
+//! A validator is a node that participates in the consensus mechanism of the network.
+//! Its role includes block production, transaction validation, network integrity and security
+//! maintenance.
+//!
+//! #### Collator
+//!
+//! A collator is a node that is responsible for producing candidate blocks for the validators.
+//! Collators are similar to validators on any other blockchain but, they do not need to provide
+//! security guarantees as the Relay Chain handles this.
+//!
+//! #### Parachain
+//!
+//! Short for "parallelized chain" a parachain is a specialized blockchain that runs in parallel to
+//! the Relay Chain (Polkadot, Kusama, etc.), benefiting from the shared security and
+//! interoperability features of it.
+//!
+//! **Synonyms**: AppChain
+//!
+//! #### PVF
+//! The Parachain Validation Function (PVF) is the current runtime Wasm for a parachain that is
+//! stored on the Relay chain. It is an essential component in the Polkadot ecosystem, encapsulating
+//! the validation logic for each parachain. The PVF is executed by validators to verify the
+//! correctness of parachain blocks. This is critical for ensuring that each block follows the logic
+//! set by its respective parachain, thus maintaining the integrity and security of the entire
+//! network.
+//!
+//! **Synonyms**: Parachain Validation Function

+//! the Polkadot SDK.
+//!
+//! Note that this module also contains the [glossary](crate::reference_docs::glossary).
+//!
+//! ## What is a "reference document"?
+//!
+//! First, see [why we use rust-docs for everything](crate#why-rust-docs) and our documentation
+//! [principles](crate#principles). We acknowledge that as much of the crucial information should be
+//! embedded in the low level rust-docs. Then, high level scenarios should be covered in
+//! [`crate::guides`]. Finally, we acknowledge that there is a category of information that is:
+//!
+//! 1. crucial to know.
+//! 2. is too high level to be in the rust-doc of any one `type`, `trait` or `fn`.
+//! 3. is too low level to be encompassed in a [`crate::guides`].
+//!
+//! We call this class of documents "reference documents". Our goal should be to minimize the number
+//! of "reference" docs, as they incur maintenance burden.

+//! # Trait-based Programming
+//!
+//! This document walks you over a peculiar way of using Rust's `trait` items. This pattern is
+//! abundantly used within [`frame`] and is therefore paramount important for a smooth transition
+//! into it.
+//!
+//! The rest of this document assumes familiarity with the
+//! [Rust book's Advanced Traits](https://doc.rust-lang.org/book/ch19-03-advanced-traits.html)
+//! section.
+//! Moreover, we use the [`frame::traits::Get`].
+//!
+//! First, imagine we are writing a FRAME pallet. We represent this pallet with a `struct Pallet`,
+//! and this pallet wants to implement the functionalities of that pallet, for example a simple
+//! `transfer` function. For the sake of education, we are interested in having a `MinTransfer`
+//! amount, expressed as a [`frame::traits::Get`], which will dictate what is the minimum amount
+//! that can be transferred.
+//!
+//! We can foremost write this as simple as the following snippet:
+#![doc = docify::embed!("./src/reference_docs/trait_based_programming.rs", basic)]
+//!
+//!
+//! In this example, we use arbitrary choices for `AccountId`, `Balance` and the `MinTransfer` type.
+//! This works great for **one team's purposes** but we have to remember that Substrate and FRAME
+//! are written as generic frameworks, intended to be highly configurable.
+//!
+//! In a broad sense, there are two avenues in exposing configurability:
+//!
+//! 1. For *values* that need to be generic, for example `MinTransfer`, we attach them to the
+//!    `Pallet` struct as fields:
+//!
+//! ```
+//! struct Pallet {
+//! 	min_transfer: u128,
+//! }
+//! ```
+//!
+//! 2. For *types* that need to be generic, we would have to use generic or associated types, such
+//!    as:
+//!
+//! ```
+//! struct Pallet<AccountId> {
+//! 	min_transfer: u128,
+//!     _marker: std::marker::PhantomData<AccountId>,
+//! }
+//! ```
+//!
+//! Substrate and FRAME, for various reasons (performance, correctness, type safety) has opted to
+//! use *types* to declare both *values* and *types* as generic. This is the essence of why the
+//! `Get` trait exists.
+//!
+//! This would bring us to the second iteration of the pallet, which would look like:
+#![doc = docify::embed!("./src/reference_docs/trait_based_programming.rs", generic)]
+//!
+//! In this example, we managed to make all 3 of our types generic. Taking the example of the
+//! `AccountId`, one should read the above as following:
+//!
+//! > The `Pallet` does not know what type `AccountId` concretely is, but it knows that it is
+//! > something that adheres to being `From<[u8; 32]>`.
+//!
+//! This method would work, but it suffers from two downsides:
+//!
+//! 1. It is verbose, each `impl` block would have to reiterate all of the trait bounds.
+//! 2. It cannot easily share/inherit generic types. Imagine multiple pallets wanting to be generic
+//!    over a single `AccountId`. There is no easy way to express that in this model.
+//!
+//! Finally, this brings us to using traits and associated types on traits to express the above.
+//! Trait associated types have the benefit of:
+//!
+//! 1. Being less verbose, as in effect they can *group multiple `type`s together*.
+//! 2. Can inherit from one another by declaring
+//! [supertraits](https://doc.rust-lang.org/rust-by-example/trait/supertraits.html).
+//!
+//! > Interestingly, one downside of associated types is that declaring defaults on them is not
+//! > stable yet. In the meantime, we have built our own custom mechanics around declaring defaults
+//! for associated types, see [`pallet_default_config_example`].
+//!
+//! The last iteration of our code would look like this:
+#![doc = docify::embed!("./src/reference_docs/trait_based_programming.rs", trait_based)]
+//!
+//! Notice how instead of having multiple generics, everything is generic over a single `<T:
+//! Config>`, and all types are fetched through `T`, for example `T::AccountId`, `T::MinTransfer`.
+//!
+//! Finally, imagine all pallets wanting to be generic over `AccountId`. This can be achieved by
+//! having individual `trait Configs` declare a shared `trait SystemConfig` as their
+//! [supertrait](https://doc.rust-lang.org/rust-by-example/trait/supertraits.html).
+#![doc = docify::embed!("./src/reference_docs/trait_based_programming.rs", with_system)]
+//! In FRAME, this shared supertrait is [`frame::prelude::frame_system`].
+//!
+//! Notice how this made no difference in the syntax of the rest of the code. `T::AccountId` is
+//! still a valid type, since `T` implements `Config` and `Config` implies `SystemConfig`, which
+//! has a `type AccountId`.
+//!
+//! Note, in some instances one would need to use what is known as the fully-qualified-syntax to
+//! access a type to help the Rust compiler disambiguate.
+#![doc = docify::embed!("./src/reference_docs/trait_based_programming.rs", fully_qualified)]
+//!
+//! This syntax can sometimes become more complicated when you are dealing with nested traits.
+//! Consider the following example, in which we fetch the `type Balance` from another trait
+//! `CurrencyTrait`.
+#![doc = docify::embed!("./src/reference_docs/trait_based_programming.rs", fully_qualified_complicated)]
+//!
+//! Notice the final `type BalanceOf` and how it is defined. Using such aliases to shorten the
+//! length of fully qualified syntax is a common pattern in FRAME.
+//!
+//! The above example is almost identical to the well-known (and somewhat notorious) `type
+//! BalanceOf` that is often used in the context of [`frame::traits::fungible`].
+#![doc = docify::embed!("../../substrate/frame/fast-unstake/src/types.rs", BalanceOf)]

+//! # WASM Meta Protocol
+//!
+//! All Substrate based chains adhere to a unique architectural design novel to the Polkadot
+//! ecosystem. We refer to this design as the "WASM Meta Protocol".
+//!
+//! Consider the fact that a traditional blockchain software is usually a monolithic artifact.
+//! Upgrading any part of the system implies upgrading the entire system. This has historically led
+//! to cumbersome forkful upgrades to be the status quo in the blockchain ecosystem.
+//!
+//! Moreover, the idea of "storing code in the state" is explored in the context of smart contracts
+//! platforms, but has not been expanded further.
+//!
+//! Substrate mixes these two ideas together, and takes the novel approach of storing the
+//! blockchain's main "state transition function" in the main blockchain state, in the same fashion
+//! that a smart contract platform stores the code of individual contracts in its state. As noted in
+//! [`crate::reference_docs::blockchain_state_machines`], this state transition function is called
+//! the **Runtime**, and WASM is chosen as the bytecode. The Runtime is stored under a special key
+//! in the state (see
+//! [`sp_core::storage::well_known_keys`](../../../sp_core/index.html)) and can be
+//! updated as a part of the state transition function's execution, just like a user's account
+//! balance can be updated.
+//!
+//! > Note that while we drew an analogy between smart contracts and runtimes in the above, there
+//! > are fundamental differences between the two, explained in
+//! > [`crate::reference_docs::runtime_vs_smart_contract`].
+//!
+//! The rest of the system that is NOT the state transition function is called the **node**, and
+//! is a normal binary that is compiled from Rust to different hardware targets.
+//!
+//! This design enables all Substrate-based chains to be fork-less-ly upgradeable, because the
+//! Runtime can be updates on the fly, within the execution of a block, and the node is (for the
+//! most part) oblivious to the change that is happening.
+//!
+//! Therefore, the high-level architecture of a any Substrate-based chain can be demonstrated as
+//! follows:
+#![doc = simple_mermaid::mermaid!("../../../mermaid/substrate_simple.mmd")]
+//!
+//! The node and the runtime need to communicate. This is done through two concepts:
+//!
+//! 1. **Host functions**: a way for the (WASM) runtime to talk to the node. All host functions are
+//!    defined in [`sp_io`]. For example, [`sp_io::storage`] are the set of host functions that
+//!    allow the runtime to read and write data to the on-chain state.
+//! 2. **Runtime APIs**: a way for the node to talk to the WASM runtime. Runtime APIs are defined
+//!    using macros and utilities in [`sp_api`]. For example, [`sp_api::Core`] is the most
+//!    fundamental runtime API that any blockchain must implement in order to be able to (re)
+//!    execute blocks.
+#![doc = simple_mermaid::mermaid!("../../../mermaid/substrate_client_runtime.mmd")]
+//!
+//! A runtime must have a set of runtime APIs in order to have any meaningful blockchain
+//! functionality, but it can also expose more APIs. See TODO as an example of how to add custom
+//! runtime APIs to your FRAME-based runtime.
+//!
+//! Similarly, for a runtime to be "compatible" with a node, the node must implement the full set of
+//! host functions that the runtime at any point in time requires. Given the fact that a runtime can
+//! evolve in time, and a blockchain node (typically) wishes to be capable of re-executing all the
+//! previous blocks, this means that a node must always maintain support for the old host functions.
+//! This also implies that adding a new host function is a big commitment and should be done with
+//! care. This is why, for example, adding a new host function to Polkadot always requires an RFC.
+//!
+//! ## Node vs. Runtime
+//!
+//! A common question is: which components of the system end up being part of the node, and which
+//! ones of the runtime?
+//!
+//! Recall from [`crate::reference_docs::blockchain_state_machines`] that the runtime is the state
+//! transition function. Anything that needs to influence how your blockchain's state is updated,
+//! should be a part of the runtime. For example, the logic around currency, governance, identity or
+//! any other application-specific logic that has to do with the state is part of the runtime.
+//!
+//! Anything that does not have to do with the state-transition function and will only
+//! facilitate/enable it is part of the node. For example, the database, networking, and even
+//! consensus algorithm are all node-side components.
+//!
+//! > The consensus is to your runtime what HTTP is to a web-application. It is the underlying
+//! > engine that enables trustless execution of the runtime in a distributed manner whilst
+//! > maintaining a canonical outcome of that execution.
+#![doc = simple_mermaid::mermaid!("../../../mermaid/substrate_with_frame.mmd")]
+//!
+//! ## State
+//!
+//! From the previous sections, we know that the a database component is part of the node, not the
+//! runtime. We also hinted that a set of host functions ([`sp_io::storage`]) are how the runtime
+//! issues commands to the node to read/write to the state. Let's dive deeper into this.
+//!
+//! The state of the blockchain, what we seek to come to consensus about, is indeed *kept* in the
+//! node side. Nonetheless, the runtime is the only component that:
+//!
+//! 1. Can update the state.
+//! 2. Can fully interpret the state.
+//!
+//! In fact, [`sp_core::storage::well_known_keys`] are the only state keys that the node side is
+//! aware of. The rest of the state, including what logic the runtime has, what balance each user
+//! has and such are all only comprehensible to the runtime.
+#![doc = simple_mermaid::mermaid!("../../../mermaid/state.mmd")]
+//!
+//! In the above diagram, all of the state keys and values are opaque bytes to the node. The node
+//! does not know what they mean, and it does not now what is the type of the corresponding value
+//! (e.g. if it is a number of a vector). Contrary, the runtime knows both the meaning of their
+//! keys, and the type of the values.
+//!
+//! This opaque-ness is the fundamental reason why Substrate-based chains can fork-less-ly upgrade:
+//! because the node side code is kept oblivious to all of the details of the state transition
+//! function. Therefore, the state transition function can freely upgrade without the node needing
+//! to know.
+//!
+//! ## Native Runtime

-# Release Checklist
-
-This is the release checklist for Polkadot {{ env.VERSION }}. **All** following
-checks should be completed before publishing a new release of the
-Polkadot/Kusama/Westend/Rococo runtime or client. The current release candidate can be
-checked out with `git checkout release-{{ env.VERSION }}`
-
-### Runtime Releases
-
-These checks should be performed on the codebase prior to forking to a release-
-candidate branch.
-
-- [ ] Verify [`spec_version`](https://github.com/paritytech/polkadot/blob/master/doc/release-checklist.md#spec-version) has been incremented since the
-    last release for any native runtimes from any existing use on public
-    (non-private) networks. If the runtime was published (release or pre-release), either
-    the `spec_version` or `impl` must be bumped.
-- [ ] Verify previously [completed migrations](https://github.com/paritytech/polkadot/blob/master/doc/release-checklist.md#old-migrations-removed) are
-    removed for any public (non-private/test) networks.
-- [ ] Verify pallet and [extrinsic ordering](https://github.com/paritytech/polkadot/blob/master/doc/release-checklist.md#extrinsic-ordering) has stayed
-    the same. Bump `transaction_version` if not.
-- [ ] Verify new extrinsics have been correctly whitelisted/blacklisted for
-    [proxy filters](https://github.com/paritytech/polkadot/blob/master/doc/release-checklist.md#proxy-filtering).
-- [ ] Verify [benchmarks](https://github.com/paritytech/polkadot/blob/master/doc/release-checklist.md#benchmarks) have been updated for any modified
-    runtime logic.
-
-The following checks can be performed after we have forked off to the release-
-candidate branch or started an additional release candidate branch (rc-2, rc-3, etc)
-
-- [ ] Verify [new migrations](https://github.com/paritytech/polkadot/blob/master/doc/release-checklist.md#new-migrations) complete successfully, and the
-    runtime state is correctly updated for any public (non-private/test)
-    networks.
-- [ ] Verify [Polkadot JS API](https://github.com/paritytech/polkadot/blob/master/doc/release-checklist.md#polkadot-js) are up to date with the latest
-    runtime changes.
-- [ ] Check with the Signer's team to make sure metadata update QR are lined up
-- [ ] Push runtime upgrade to Westend and verify network stability.
-
-### All Releases
-
-- [ ] Check that the new client versions have [run on the network](https://github.com/paritytech/polkadot/blob/master/doc/release-checklist.md#burn-in)
-    without issue for 12+ hours on >75% of our validator nodes.
-- [ ] Check that a draft release has been created at
-    https://github.com/paritytech/polkadot/releases with relevant [release
-    notes](https://github.com/paritytech/polkadot/blob/master/doc/release-checklist.md#release-notes)
-- [ ] Check that [build artifacts](https://github.com/paritytech/polkadot/blob/master/doc/release-checklist.md#build-artifacts) have been added to the
-    draft-release
-- [ ] Check that all items listed in the [milestone](https://github.com/paritytech/polkadot/milestones) are included in the release.
-- [ ] Ensure that no `freenotes` were added into the release branch after the latest generated RC

 ## Installation
 
+### Using a pre-compiled binary
+
 If you just wish to run a Polkadot node without compiling it yourself, you may either run the latest
 binary from our [releases](https://github.com/paritytech/polkadot-sdk/releases) page, or install
 Polkadot from one of our package repositories.
 
-Installation from the Debian repository will create a `systemd` service that can be used to run a
-Polkadot node. This is disabled by default, and can be started by running `systemctl start polkadot`
-on demand (use `systemctl enable polkadot` to make it auto-start after reboot). By default, it will
-run as the `polkadot` user.  Command-line flags passed to the binary can be customized by editing
-`/etc/default/polkadot`. This file will not be overwritten on updating Polkadot. You may also just
-run the node directly from the command-line.

 ### Build from Source
 
-If you'd like to build from source, first install Rust. You may need to add Cargo's bin directory to
-your PATH environment variable. Restarting your computer will do this for you automatically.
-
-```bash
-curl https://sh.rustup.rs -sSf | sh
-```
-
-If you already have Rust installed, make sure you're using the latest version by running:
-
-```bash
-rustup update
-```
-
-Once done, finish installing the support software:
-
-```bash
-sudo apt install build-essential git clang libclang-dev pkg-config libssl-dev protobuf-compiler
-```
-
 Build the client by cloning this repository and running the following commands from the root
 directory of the repo:
 
 ```bash
 git checkout <latest tagged release>
-./scripts/init.sh
 cargo build --release
 ```
 
-**Note:** compilation is a memory intensive process. We recommend having 4 GiB of physical RAM or
-swap available (keep in mind that if a build hits swap it tends to be very slow).
-
 **Note:** if you want to move the built `polkadot` binary somewhere (e.g. into $PATH) you will also
 need to move `polkadot-execute-worker` and `polkadot-prepare-worker`. You can let cargo do all this

+Launching small scale networks, with multiple adversarial nodes. This should include tests around the thresholds in
+order to evaluate the error handling once certain assumed invariants fail.
+
+Currently, we commonly use **zombienet** to run mini test-networks, whether locally or in CI. To run on your machine:
+
+- First, make sure you have [zombienet][zombienet] installed.
+
+- Now, all the required binaries must be installed in your $PATH. You must run the following from the `polkadot/`
+directory in order to test your changes. (Not `zombienet setup`, or you will get the released binaries without your
+local changes!)
 
-For this purpose based on `AllSubsystems` and `proc-macro` `AllSubsystemsGen`.
+```sh
+cargo install --path . --locked
+```
+
+- You will also need to install whatever binaries are required for your specific tests. For example, to install
+`undying-collator`, from `polkadot/`, run:
+
+```sh
+cargo install --path ./parachain/test-parachains/undying/collator --locked
+```
 
-This assumes a simplistic test runtime.
+- Finally, run the zombienet test from the `polkadot` directory:
+
+```sh
+RUST_LOG=parachain::pvf=trace zombienet --provider=native spawn zombienet_tests/functional/0001-parachains-pvf.toml
+```
+
+- You can pick a validator node like `alice` from the output and view its logs
+(`tail -f <log_file>`) or metrics. Make sure there is nothing funny in the logs
+(try `grep WARN <log_file>`).

 _Behavior tests_ and _testing at scale_ have naturally soft boundary. The most significant difference is the presence of
 a real network and the number of nodes, since a single host often not capable to run multiple nodes at once.
 
----
+## Observing Logs
+
+To verify expected behavior it's often useful to observe logs. To avoid too many
+logs at once, you can run one test at a time:
+
+1. Add `sp_tracing::try_init_simple();` to the beginning of a test
+2. Specify `RUST_LOG=<target>::<subtarget>=trace` before the cargo command.

+For example:

+# PVF Host
+
+This is the PVF host, responsible for responding to requests from Candidate
+Validation and spawning worker tasks to fulfill those requests.
+
+See also:
+
+- for more information: [the Implementer's Guide][impl-guide]
+- for an explanation of terminology: [the Glossary][glossary]
+
+## Running basic tests
+
+Running `cargo test` in the `pvf/` directory will run unit and integration
+tests.
+
+**Note:** some tests run only under Linux, amd64, and/or with the
+`ci-only-tests` feature enabled.
+
+See the general [Testing][testing] instructions for more information on
+**running tests** and **observing logs**.
+
+## Running a test-network with zombienet
+
+Since this crate is consensus-critical, for major changes it is highly
+recommended to run a test-network. See the "Behavior tests" section of the
+[Testing][testing] docs for full instructions.
+
+To run the PVF-specific zombienet test:
+
+```sh
+RUST_LOG=parachain::pvf=trace zombienet --provider=native spawn zombienet_tests/functional/0001-parachains-pvf.toml
+```
+
+## Testing on Linux
+
+Some of the PVF functionality, especially related to security, is Linux-only,
+and some is amd64-only. If you touch anything security-related, make sure to
+test on Linux amd64! If you're on a Mac, you can either run a VM or you can hire
+a VPS and use the open-source tool [EternalTerminal][et] to connect to it.[^et]
+
+[^et]: Unlike ssh, ET preserves your session across disconnects, and unlike
+another popular persistent shell, mosh, it allows scrollback.

+//! Functionality for sandboxing workers by restricting their capabilities by blocking certain
+//! syscalls with seccomp.
+//!
+//! For security we block the following:
+//!
+//! - creation of new sockets - these are unneeded in PVF jobs, and we can safely block them without
+//!   affecting consensus.
+//!
+//! - `io_uring` - allows for networking and needs to be blocked. See below for a discussion on the
+//!   safety of doing this.
+//!
+//! # Safety of blocking io_uring
+//!
+//! `io_uring` is just a way of issuing system calls in an async manner, and there is nothing
+//! stopping wasmtime from legitimately using it. Fortunately, at the moment it does not. Generally,
+//! not many applications use `io_uring` in production yet, because of the numerous kernel CVEs
+//! discovered. It's still under a lot of development. Android outright banned `io_uring` for these
+//! reasons.
+//!
+//! Considering `io_uring`'s status discussed above, and that it very likely would get detected
+//! either by our [static analysis](https://github.com/paritytech/polkadot-sdk/pull/1663) or by
+//! testing, we think it is safe to block it.
+//!
+//! ## Consensus analysis
+//!
+//! If execution hits an edge case code path unique to a given machine, it's already taken a
+//! non-deterministic branch anyway. After all, we just care that the majority of validators reach
+//! the same result and preserve consensus. So worst-case scenario, there's a dispute, and we can
+//! always admit fault and refund the wrong validator. On the other hand, if all validators take the
+//! code path that results in a seccomp violation, then they would all vote against the current
+//! candidate, which is also fine. The violation would get logged (in big scary letters) and
+//! hopefully some validator reports it to us.
+//!
+//! Actually, a worst-worse-case scenario is that 50% of validators vote against, so that there is
+//! no consensus. But so many things would have to go wrong for that to happen:
+//!
+//! 1. An update to `wasmtime` is introduced that uses io_uring (unlikely as io_uring is mainly for
+//!    IO-heavy applications)
+//!
+//! 2. The new syscall is not detected by our static analysis
+//!
+//! 3. It is never triggered in any of our tests
+//!
+//! 4. It then gets triggered on some super edge case in production on 50% of validators causing a
+//!    stall (bad but very unlikely)
+//!
+//! 5. Or, it triggers on only a few validators causing a dispute (more likely but not as bad)
+//!
+//! Considering how many things would have to go wrong here, we believe it's safe to block
+//! `io_uring`.
+//!
+//! # Action on syscall violations
+//!
+//! When a forbidden syscall is attempted we immediately kill the process in order to prevent the
+//! attacker from doing anything else. In execution, this will result in voting against the
+//! candidate.

+//! A malicious node variant that attempts to dispute finalized candidates.
+//!
+//! This malus variant behaves honestly in backing and approval voting.
+//! The maliciousness comes from emitting an extra dispute statement on top of the other ones.
+//!
+//! Some extra quirks which generally should be insignificant:
+//! - The malus node will not dispute at session boundaries
+//! - The malus node will not dispute blocks it backed itself
+//! - Be cautious about the size of the network to make sure disputes are not auto-confirmed
+//! (7 validators is the smallest network size as it needs [(7-1)//3]+1 = 3 votes to get
+//! confirmed but it only gets 1 from backing and 1 from malus so 2 in total)
+//!
+//!
+//! Attention: For usage with `zombienet` only!

+/// # Overview
+///
+/// A set of utilities for node-side code to emulate the logic the runtime uses for checking
+/// parachain blocks in order to build prospective parachains that are produced ahead of the
+/// relay chain. These utilities allow the node-side to predict, with high accuracy, what
+/// the relay-chain will accept in the near future.
+///
+/// This module has 2 key data types: [`Constraints`] and [`Fragment`]s. [`Constraints`]
+/// exhaustively define the set of valid inputs and outputs to parachain execution. A
+/// [`Fragment`] indicates a parachain block, anchored to the relay-chain at a particular
+/// relay-chain block, known as the relay-parent.
+///
+/// ## Fragment Validity
+///
+/// Every relay-parent is implicitly associated with a unique set of [`Constraints`] that
+/// describe the properties that must be true for a block to be included in a direct child of
+/// that block, assuming there is no intermediate parachain block pending availability.
+///
+/// However, the key factor that makes asynchronously-grown prospective chains
+/// possible is the fact that the relay-chain accepts candidate blocks based on whether they
+/// are valid under the constraints of the present moment, not based on whether they were
+/// valid at the time of construction.
+///
+/// As such, [`Fragment`]s are often, but not always constructed in such a way that they are
+/// invalid at first and become valid later on, as the relay chain grows.
+///
+/// # Usage
+///
+/// It's expected that the users of this module will be building up trees of
+/// [`Fragment`]s and consistently pruning and adding to the tree.
+///
+/// ## Operating Constraints
+///
+/// The *operating constraints* of a `Fragment` are the constraints with which that fragment
+/// was intended to comply. The operating constraints are defined as the base constraints
+/// of the relay-parent of the fragment modified by the cumulative modifications of all
+/// fragments between the relay-parent and the current fragment.
+///
+/// What the operating constraints are, in practice, is a prediction about the state of the
+/// relay-chain in the future. The relay-chain is aware of some current state, and we want to
+/// make an intelligent prediction about what might be accepted in the future based on
+/// prior fragments that also exist off-chain.
+///
+/// ## Fragment Trees
+///
+/// As the relay-chain grows, some predictions come true and others come false.
+/// And new predictions get made. These three changes correspond distinctly to the
+/// 3 primary operations on fragment trees.
+///
+/// A fragment tree is a mental model for thinking about a forking series of predictions
+/// about a single parachain. There may be one or more fragment trees per parachain.
+///
+/// In expectation, most parachains will have a plausibly-unique authorship method which means
+/// that they should really be much closer to fragment-chains, maybe with an occasional fork.
+///
+/// Avoiding fragment-tree blowup is beyond the scope of this module.
+///
+/// ### Pruning Fragment Trees
+///
+/// When the relay-chain advances, we want to compare the new constraints of that relay-parent
+/// to the roots of the fragment trees we have. There are 3 cases:
+///
+/// 1. The root fragment is still valid under the new constraints. In this case, we do nothing.
+///    This is the "prediction still uncertain" case.
+///
+/// 2. The root fragment is invalid under the new constraints because it has been subsumed by
+///    the relay-chain. In this case, we can discard the root and split & re-root the fragment
+///    tree under its descendents and compare to the new constraints again. This is the
+///    "prediction came true" case.
+///
+/// 3. The root fragment is invalid under the new constraints because a competing parachain
+///    block has been included or it would never be accepted for some other reason. In this
+///    case we can discard the entire fragment tree. This is the "prediction came false" case.
+///
+/// This is all a bit of a simplification because it assumes that the relay-chain advances
+/// without forks and is finalized instantly. In practice, the set of fragment-trees needs to
+/// be observable from the perspective of a few different possible forks of the relay-chain and
+/// not pruned too eagerly.
+///
+/// Note that the fragments themselves don't need to change and the only thing we care about
+/// is whether the predictions they represent are still valid.
+///
+/// ### Extending Fragment Trees
+///
+/// As predictions fade into the past, new ones should be stacked on top.
+///
+/// Every new relay-chain block is an opportunity to make a new prediction about the future.
+/// Higher-level logic should select the leaves of the fragment-trees to build upon or whether
+/// to create a new fragment-tree.
+///
+/// ### Code Upgrades
+///
+/// Code upgrades are the main place where this emulation fails. The on-chain PVF upgrade
+/// scheduling logic is very path-dependent and intricate so we just assume that code upgrades
+/// can't be initiated and applied within a single fragment-tree. Fragment-trees aren't deep,
+/// in practice and code upgrades are fairly rare. So what's likely to happen around code
+/// upgrades is that the entire fragment-tree has to get discarded at some point.
+///
+/// That means a few blocks of execution time lost, which is not a big deal for code upgrades
+/// in practice at most once every few weeks.

-//! The implementation of the inclusion emulator for the 'staging' runtime version.
-//!
-//! # Overview
-//!
-//! A set of utilities for node-side code to emulate the logic the runtime uses for checking
-//! parachain blocks in order to build prospective parachains that are produced ahead of the
-//! relay chain. These utilities allow the node-side to predict, with high accuracy, what
-//! the relay-chain will accept in the near future.
-//!
-//! This module has 2 key data types: [`Constraints`] and [`Fragment`]s. [`Constraints`]
-//! exhaustively define the set of valid inputs and outputs to parachain execution. A [`Fragment`]
-//! indicates a parachain block, anchored to the relay-chain at a particular relay-chain block,
-//! known as the relay-parent.
-//!
-//! ## Fragment Validity
-//!
-//! Every relay-parent is implicitly associated with a unique set of [`Constraints`] that describe
-//! the properties that must be true for a block to be included in a direct child of that block,
-//! assuming there is no intermediate parachain block pending availability.
-//!
-//! However, the key factor that makes asynchronously-grown prospective chains
-//! possible is the fact that the relay-chain accepts candidate blocks based on whether they
-//! are valid under the constraints of the present moment, not based on whether they were
-//! valid at the time of construction.
-//!
-//! As such, [`Fragment`]s are often, but not always constructed in such a way that they are
-//! invalid at first and become valid later on, as the relay chain grows.
-//!
-//! # Usage
-//!
-//! It's expected that the users of this module will be building up trees of
-//! [`Fragment`]s and consistently pruning and adding to the tree.
-//!
-//! ## Operating Constraints
-//!
-//! The *operating constraints* of a `Fragment` are the constraints with which that fragment
-//! was intended to comply. The operating constraints are defined as the base constraints
-//! of the relay-parent of the fragment modified by the cumulative modifications of all
-//! fragments between the relay-parent and the current fragment.
-//!
-//! What the operating constraints are, in practice, is a prediction about the state of the
-//! relay-chain in the future. The relay-chain is aware of some current state, and we want to
-//! make an intelligent prediction about what might be accepted in the future based on
-//! prior fragments that also exist off-chain.
-//!
-//! ## Fragment Trees
-//!
-//! As the relay-chain grows, some predictions come true and others come false.
-//! And new predictions get made. These three changes correspond distinctly to the
-//! 3 primary operations on fragment trees.
-//!
-//! A fragment tree is a mental model for thinking about a forking series of predictions
-//! about a single parachain. There may be one or more fragment trees per parachain.
-//!
-//! In expectation, most parachains will have a plausibly-unique authorship method which means that
-//! they should really be much closer to fragment-chains, maybe with an occasional fork.
-//!
-//! Avoiding fragment-tree blowup is beyond the scope of this module.
-//!
-//! ### Pruning Fragment Trees
-//!
-//! When the relay-chain advances, we want to compare the new constraints of that relay-parent to
-//! the roots of the fragment trees we have. There are 3 cases:
-//!
-//! 1. The root fragment is still valid under the new constraints. In this case, we do nothing. This
-//! is the "prediction still uncertain" case.
-//!
-//! 2. The root fragment is invalid under the new constraints because it has been subsumed by the
-//! relay-chain. In this case, we can discard the root and split & re-root the fragment tree under
-//! its descendents and compare to the new constraints again. This is the "prediction came true"
-//! case.
-//!
-//! 3. The root fragment is invalid under the new constraints because a competing parachain block
-//! has been included or it would never be accepted for some other reason. In this case we can
-//! discard the entire fragment tree. This is the "prediction came false" case.
-//!
-//! This is all a bit of a simplification because it assumes that the relay-chain advances without
-//! forks and is finalized instantly. In practice, the set of fragment-trees needs to be observable
-//! from the perspective of a few different possible forks of the relay-chain and not pruned
-//! too eagerly.
-//!
-//! Note that the fragments themselves don't need to change and the only thing we care about
-//! is whether the predictions they represent are still valid.
-//!
-//! ### Extending Fragment Trees
-//!
-//! As predictions fade into the past, new ones should be stacked on top.
-//!
-//! Every new relay-chain block is an opportunity to make a new prediction about the future.
-//! Higher-level logic should select the leaves of the fragment-trees to build upon or whether
-//! to create a new fragment-tree.
-//!
-//! ### Code Upgrades
-//!
-//! Code upgrades are the main place where this emulation fails. The on-chain PVF upgrade scheduling
-//! logic is very path-dependent and intricate so we just assume that code upgrades
-//! can't be initiated and applied within a single fragment-tree. Fragment-trees aren't deep,
-//! in practice and code upgrades are fairly rare. So what's likely to happen around code
-//! upgrades is that the entire fragment-tree has to get discarded at some point.
-//!
-//! That means a few blocks of execution time lost, which is not a big deal for code upgrades
-//! in practice at most once every few weeks.

+//! This pallet is designed to go into a source chain and destination chain to migrate data. The
+//! design motivations are:
+//!
+//! - Call some function on the source chain that executes some migration (clearing state,
+//!   forwarding an XCM program).
+//! - Call some function (probably from an XCM program) on the destination chain.
+//! - Avoid cluttering the source pallet with new dispatchables that are unrelated to its
+//!   functionality and only used for migration.
+//!
+//! After the migration is complete, the pallet may be removed from both chains' runtimes as well as
+//! the `polkadot-runtime-common` crate.

+title: Fix for Reward Deficit in the pool
+
+doc:
+  - audience: Runtime Dev
+    description: |
+      Instead of fragile calculation of current balance by looking at free balance - ED, Nomination Pool now freezes ED in the pool reward account to restrict an account from going below minimum balance. This also has a nice side effect that if ED changes, we know how much is the imbalance in ED frozen in the pool and the current required ED. A pool operator can diligently top up the pool with the deficit in ED or vice versa, withdraw the excess they transferred to the pool.
+
+      notes:
+      - Introduces new call `adjust_pool_deposit` that allows to top up the deficit or withdraw the excess deposit for the pool.
+      - Switch to using Fungible trait from Currency trait.

+title: Supporting paged rewards allowing all nominators to be rewarded
+
+doc:
+  - audience: Node Operator
+    description: |
+      We used to clip top `MaxNominatorRewardedPerValidator` nominators by stake that are eligible for staking reward.
+      This was done to limit computation cost of paying out rewards. This PR introduces paging to reward payouts,
+      meaning we still clip nominators upto MaxExposurePageSize per page and there could be multiple pages of rewards to
+      be paid out. Validators get commission pro-rata to the amount of reward that is paid out for the page.
+
+      notes:
+        - payout_stakers should be called multiple times, once for each page of nominators.
+        - payout_stakers_by_page can be used to pay out rewards for a specific page.

+doc:

+    description: |
+      Adds a check to the try-runtime logic that will verify that all pallet on-chain storage still decodes. This can help to spot missing migrations before they become a problem. The check is enabled as soon as the `--checks` option of the `try-runtime` CLI is not `None`.

+title: Different builder pattern constructors for XCM
+
+doc:
+  - audience: Runtime Dev
+    description: |
+      The `builder()` constructor for XCM programs now only allows building messages that pay for fees,
+      i.e. messages that would pass the `AllowTopLevelPaidExecutionFrom` barrier.
+      Another constructor, `builder_unpaid()` requires an explicit `UnpaidExecution` instruction before
+      anything else.
+      For building messages without any restriction, `builder_unsafe` can be used.
+      This has been named like that since in general the other two should be used instead, but it's okay
+      to use it for teaching purposes or for experimenting.

 Substrate chain configurations.
 
-This crate contains structs and utilities to declare
-a runtime-specific configuration file (a.k.a chain spec).
-
-Basic chain spec type containing all required parameters is
-[`ChainSpec`](https://docs.rs/sc-chain-spec/latest/sc_chain_spec/struct.GenericChainSpec.html). It can be extended with
-additional options that contain configuration specific to your chain.
-Usually the extension is going to be an amalgamate of types exposed
-by Substrate core modules. To allow the core modules to retrieve
-their configuration from your extension you should use `ChainSpecExtension`
-macro exposed by this crate.
-
-```rust
-use std::collections::HashMap;
-use sc_chain_spec::{GenericChainSpec, ChainSpecExtension};
-
-#[derive(Clone, Debug, serde::Serialize, serde::Deserialize, ChainSpecExtension)]
-pub struct MyExtension {
-		pub known_blocks: HashMap<u64, String>,
-}
-
-pub type MyChainSpec<G> = GenericChainSpec<G, MyExtension>;
-```
-
-Some parameters may require different values depending on the
-current blockchain height (a.k.a. forks). You can use `ChainSpecGroup`
-macro and provided [`Forks`](https://docs.rs/sc-chain-spec/latest/sc_chain_spec/struct.Forks.html) structure to put
-such parameters to your chain spec.
-This will allow to override a single parameter starting at specific
-block number.
-
-```rust
-use sc_chain_spec::{Forks, ChainSpecGroup, ChainSpecExtension, GenericChainSpec};
-
-#[derive(Clone, Debug, serde::Serialize, serde::Deserialize, ChainSpecGroup)]
-pub struct ClientParams {
-		max_block_size: usize,
-		max_extrinsic_size: usize,
-}
-
-#[derive(Clone, Debug, serde::Serialize, serde::Deserialize, ChainSpecGroup)]
-pub struct PoolParams {
-		max_transaction_size: usize,
-}
-
-#[derive(Clone, Debug, serde::Serialize, serde::Deserialize, ChainSpecGroup, ChainSpecExtension)]
-pub struct Extension {
-		pub client: ClientParams,
-		pub pool: PoolParams,
-}
-
-pub type BlockNumber = u64;
-
-/// A chain spec supporting forkable `ClientParams`.
-pub type MyChainSpec1<G> = GenericChainSpec<G, Forks<BlockNumber, ClientParams>>;
-
-/// A chain spec supporting forkable `Extension`.
-pub type MyChainSpec2<G> = GenericChainSpec<G, Forks<BlockNumber, Extension>>;
-```
-
-It's also possible to have a set of parameters that is allowed to change
-with block numbers (i.e. is forkable), and another set that is not subject to changes.
-This is also possible by declaring an extension that contains `Forks` within it.
-
-
-```rust
-use serde::{Serialize, Deserialize};
-use sc_chain_spec::{Forks, GenericChainSpec, ChainSpecGroup, ChainSpecExtension};
-
-#[derive(Clone, Debug, Serialize, Deserialize, ChainSpecGroup)]
-pub struct ClientParams {
-		max_block_size: usize,
-		max_extrinsic_size: usize,
-}
-
-#[derive(Clone, Debug, Serialize, Deserialize, ChainSpecGroup)]
-pub struct PoolParams {
-		max_transaction_size: usize,
-}
-
-#[derive(Clone, Debug, Serialize, Deserialize, ChainSpecExtension)]
-pub struct Extension {
-		pub client: ClientParams,
-		#[forks]
-		pub pool: Forks<u64, PoolParams>,
-}
-
-pub type MyChainSpec<G> = GenericChainSpec<G, Extension>;

-//! Substrate chain configurations.
+//! This crate includes structs and utilities for defining configuration files (known as chain
+//! specification) for both runtime and node.
+//!
+//! # Intro: Chain Specification
+//!
+//! The chain specification comprises parameters and settings that define the properties and an
+//! initial state of a chain. Users typically interact with the JSON representation of the chain
+//! spec. Internally, the chain spec is embodied by the [`GenericChainSpec`] struct, and specific
+//! properties can be accessed using the [`ChainSpec`] trait.
+//!
+//! In summary, although not restricted to, the primary role of the chain spec is to provide a list
+//! of well-known boot nodes for the blockchain network and the means for initializing the genesis
+//! storage. This initialization is necessary for creating a genesis block upon which subsequent
+//! blocks are built. When the node is launched for the first time, it reads the chain spec,
+//! initializes the genesis block, and establishes connections with the boot nodes.
+//!
+//! The JSON chain spec is divided into two main logical sections:
+//! - one section details general chain properties,
+//! - second explicitly or indirectly defines the genesis storage, which, in turn, determines the
+//!   genesis hash of the chain,
+//!
+//! The chain specification consists of the following fields:
+//!
+//! <table>
+//!   <thead>
+//!     <tr>
+//!       <th>Chain spec key</th>
+//!       <th>Description</th>
+//!     </tr>
+//!   </thead>
+//!   <tbody>
+//!     <tr>
+//!       <td>name</td>
+//!       <td>The human readable name of the chain.</td>
+//!     </tr>
+//!     <tr>
+//!       <td>id</td>
+//!       <td>The id of the chain.</td>
+//!     </tr>
+//!     <tr>

+//!           (refer to
+//!            <a href="enum.ChainType.html" title="enum sc_chain_spec::ChainType">

+//!     <tr>

+//!       <td>Optional list of <code>multi address, verbosity</code> of telemetry endpoints. The

+//! the network level when two chains have the same genesis hash.</td>

+//!       <td>Custom properties. Shall be provided in the form of

+//!       <td>genesis</td>

+//!   </tbody>
+//! </table>
+//!
+//! # `genesis`: Initial Runtime State
+//!
+//! All nodes in the network must build subsequent blocks upon exactly the same genesis block.
+//!
+//! The information configured in the `genesis` section of a chain specification is used to build
+//! the genesis storage, which is essential for creating the genesis block, since the block header
+//! includes the storage root hash.
+//!
+//! The `genesis` key of the chain specification definition describes the
+//! initial state of the runtime. For example, it may contain:
+//! - an initial list of funded accounts,
+//! - the administrative account that controls the sudo key,
+//! - an initial authorities set for consensus, etc.
+//!
+//! As the compiled WASM blob of the runtime code is stored in the chain's state, the initial
+//! runtime must also be provided within the chain specification.
+//!
+//! In essence, the most important formats of genesis initial state are:
+//!
+//! <table>
+//!   <thead>
+//!     <tr>
+//!       <th>Format</th>
+//!       <th>Description</th>

+//! href="../substrate_test_runtime/struct.RuntimeGenesisConfig.html#"
+//! >example of generated struct</a>). Must contain all the keys of
+//! the genesis config, no defaults will be used.
+//!
+//! This format explicitly provides the code of the runtime.

+//! For production or long-lasting blockchains, using the `raw` format in the chain specification is
+//! recommended. Only the `raw` format guarantees that storage root hash will remain unchanged when
+//! the `RuntimeGenesisConfig` format changes due to software upgrade.
+//!
+//! JSON examples in the [following section](#json-chain-specification-example) illustrate the `raw`
+//! `patch` and full genesis fields.
+//!
+//! # From Initial State to Raw Genesis.
+//!
+//! To generate a raw genesis storage from the JSON representation of the runtime genesis config,
+//! the node needs to interact with the runtime.
+//!
+//! This interaction involves passing the runtime genesis config JSON blob to the runtime using the
+//! [`sp_genesis_builder::GenesisBuilder::build_config`] function. During this operation, the
+//! runtime converts the JSON representation of the genesis config into [`sp_io::storage`] items. It
+//! is a crucial step for computing the storage root hash, which is a key component in determining
+//! the genesis hash.
+//!
+//! Consequently, the runtime must support the [`sp_genesis_builder::GenesisBuilder`] API to
+//! utilize either `patch` or `full` formats.
+//!
+//! This entire process is encapsulated within the implementation of the [`BuildStorage`] trait,
+//! which can be accessed through the [`ChainSpec::as_storage_builder`] method. There is an
+//! intermediate internal helper that facilitates this interaction,
+//! [`GenesisConfigBuilderRuntimeCaller`], which serves as a straightforward wrapper for
+//! [`sc_executor::WasmExecutor`].
+//!
+//! In case of `raw` genesis state the node does not interact with the runtime regarding the
+//! computation of initial state.
+//!
+//! The plain and `raw` chain specification JSON blobs can be found in
+//! [JSON examples](#json-chain-specification-example) section.
+//!
+//! # Optional Code Mapping
+//!
+//! Optional map of `block_number` to `wasm_code`.
+//!
+//! The given `wasm_code` will be used to substitute the on-chain wasm code starting with the
+//! given block number until the `spec_version` on-chain changes. The given `wasm_code` should
+//! be as close as possible to the on-chain wasm code. A substitute should be used to fix a bug
+//! that cannot be fixed with a runtime upgrade, if for example the runtime is constantly
+//! panicking. Introducing new runtime APIs isn't supported, because the node
+//! will read the runtime version from the on-chain wasm code.
+//!
+//! Use this functionality only when there is no other way around it, and only patch the problematic
+//! bug; the rest should be done with an on-chain runtime upgrade.
+//!
+//! # Building a Chain Specification
+//!
+//! The [`ChainSpecBuilder`] should be used to create an instance of a chain specification. Its API
+//! allows configuration of all fields of the chain spec. To generate a JSON representation of the
+//! specification, use [`ChainSpec::as_json`].
+//!
+//! The sample code to generate a chain spec is as follows:
+#![doc = docify::embed!("src/chain_spec.rs", build_chain_spec_with_patch_works)]
+//! # JSON chain specification example
+//!
+//! The following are the plain and `raw` versions of the chain specification JSON files, resulting
+//! from executing of the above [example](#building-a-chain-specification):
+//! ```ignore
+#![doc = include_str!("../res/substrate_test_runtime_from_patch.json")]
+//! ```
+//! ```ignore
+#![doc = include_str!("../res/substrate_test_runtime_from_patch_raw.json")]
+//! ```
+//! The following example shows the plain full config version of chain spec:
+//! ```ignore
+#![doc = include_str!("../res/substrate_test_runtime_from_config.json")]
+//! ```
+//! The [`ChainSpec`] trait represents the API to access values defined in the JSON chain specification.

+///
+/// `Notifications` can send two different kinds of information to protocol:
+///  * substream-related information
+///  * notification-related information
+///
+/// When an unvalidated, inbound substream is received by `Notifications`, it sends the inbound
+/// stream information (peer ID, handshake) to protocol for validation. Protocol must then verify
+/// that the handshake is valid (and in the future that it has a slot it can allocate for the peer)
+/// and then report back the `ValidationResult` which is either `Accept` or `Reject`.
+///
+/// After the validation result has been received by `Notifications`, it prepares the
+/// substream for communication by initializing the necessary sinks and emits
+/// `NotificationStreamOpened` which informs the protocol that the remote peer is ready to receive
+/// notifications.
+///
+/// Two different flavors of sending options are provided:
+///  * synchronous sending ([`NotificationService::send_sync_notification()`])
+///  * asynchronous sending ([`NotificationService::send_async_notification()`])
+///
+/// The former is used by the protocols not ready to exercise backpressure and the latter by the
+/// protocols that can do it.
+///
+/// Both local and remote peer can close the substream at any time. Local peer can do so by calling
+/// [`NotificationService::close_substream()`] which instructs `Notifications` to close the
+/// substream. Remote closing the substream is indicated to the local peer by receiving
+/// [`NotificationEvent::NotificationStreamClosed`] event.
+///
+/// In case the protocol must update its handshake while it's operating (such as updating the best
+/// block information), it can do so by calling [`NotificationService::set_handshake()`]
+/// which instructs `Notifications` to update the handshake it stored during protocol
+/// initialization.
+///
+/// All peer events are multiplexed on the same incoming event stream from `Notifications` and thus
+/// each event carries a `PeerId` so the protocol knows whose information to update when receiving
+/// an event.

+//! # Usage
+//!
+//! The `ChainSync` struct maintains the state of the block requests. Whenever something happens on

-//! Contains the state of the chain synchronization process
-//!
-//! At any given point in time, a running node tries as much as possible to be at the head of the
-//! chain. This module handles the logic of which blocks to request from remotes, and processing
-//! responses. It yields blocks to check and potentially move to the database.
-//!
-//! # Usage
-//!
-//! The `ChainSync` struct maintains the state of the block requests. Whenever something happens on
-//! the network, or whenever a block has been successfully verified, call the appropriate method in
-//! order to update it.
+//! Blockchain syncing implementation in Substrate.

-//! ### Documentation Template:<br>
-//!
-//! Copy and paste this template from frame/examples/basic/src/lib.rs into file
-//! `frame/<INSERT_CUSTOM_PALLET_NAME>/src/lib.rs` of your own custom pallet and complete it.
-//! <details><p><pre>
-//! // Add heading with custom pallet name
-//!
-//! \# <INSERT_CUSTOM_PALLET_NAME> Pallet
-//!
-//! // Add simple description
-//!
-//! // Include the following links that shows what trait needs to be implemented to use the pallet
-//! // and the supported dispatchables that are documented in the Call enum.
-//!
-//! - \[`Config`]
-//! - \[`Call`]
-//! - \[`Pallet`]
-//!
-//! \## Overview
-//!
-//! <!-- Original author of paragraph: Various. See https://github.com/paritytech/substrate-developer-hub/issues/44 -->
-//! // Short description of pallet's purpose.
-//! // Links to Traits that should be implemented.
-//! // What this pallet is for.
-//! // What functionality the pallet provides.
-//! // When to use the pallet (use case examples).
-//! // How it is used.
-//! // Inputs it uses and the source of each input.
-//! // Outputs it produces.
-//!
-//! <!-- Original author of paragraph: @Kianenigma in PR https://github.com/paritytech/substrate/pull/1951 -->
-//! <!-- and comment https://github.com/paritytech/substrate-developer-hub/issues/44#issuecomment-471982710 -->
-//!
-//! \## Terminology
-//!
-//! // Add terminology used in the custom pallet. Include concepts, storage items, or actions that
-//! you think // deserve to be noted to give context to the rest of the documentation or pallet
-//! usage. The author needs to // use some judgment about what is included. We don't want a list of
-//! every storage item nor types - the user // can go to the code for that. For example, "transfer
-//! fee" is obvious and should not be included, but // "free balance" and "reserved balance" should
-//! be noted to give context to the pallet. // Please do not link to outside resources. The
-//! reference docs should be the ultimate source of truth.
-//!
-//! <!-- Original author of heading: @Kianenigma in PR https://github.com/paritytech/substrate/pull/1951 -->
-//!
-//! \## Goals
-//!
-//! // Add goals that the custom pallet is designed to achieve.
-//!
-//! <!-- Original author of heading: @Kianenigma in PR https://github.com/paritytech/substrate/pull/1951 -->
-//!
-//! \### Scenarios
-//!
-//! <!-- Original author of paragraph: @Kianenigma. Based on PR https://github.com/paritytech/substrate/pull/1951 -->
-//!
-//! \#### <INSERT_SCENARIO_NAME>
-//!
-//! // Describe requirements prior to interacting with the custom pallet.
-//! // Describe the process of interacting with the custom pallet for this scenario and public API
-//! functions used.
-//!
-//! \## Interface
-//!
-//! \### Supported Origins
-//!
-//! // What origins are used and supported in this pallet (root, signed, none)
-//! // i.e. root when <code>\`ensure_root\`</code> used
-//! // i.e. none when <code>\`ensure_none\`</code> used
-//! // i.e. signed when <code>\`ensure_signed\`</code> used
-//!
-//! <code>\`inherent\`</code> <INSERT_DESCRIPTION>
-//!
-//! <!-- Original author of paragraph: @Kianenigma in comment -->
-//! <!-- https://github.com/paritytech/substrate-developer-hub/issues/44#issuecomment-471982710 -->
-//!
-//! \### Types
-//!
-//! // Type aliases. Include any associated types and where the user would typically define them.
-//!
-//! <code>\`ExampleType\`</code> <INSERT_DESCRIPTION>
-//!
-//! <!-- Original author of paragraph: ??? -->
-//!
-//! // Reference documentation of aspects such as `storageItems` and `dispatchable` functions should
-//! // only be included in the <https://docs.rs> Rustdocs for Substrate and not repeated in the
-//! // README file.
-//!
-//! \### Dispatchable Functions
-//!
-//! <!-- Original author of paragraph: @AmarRSingh & @joepetrowski -->
-//!
-//! // A brief description of dispatchable functions and a link to the rustdoc with their actual
-//! documentation.
-//!
-//! // <b>MUST</b> have link to Call enum
-//! // <b>MUST</b> have origin information included in function doc
-//! // <b>CAN</b> have more info up to the user
-//!
-//! \### Public Functions
-//!
-//! <!-- Original author of paragraph: @joepetrowski -->
-//!
-//! // A link to the rustdoc and any notes about usage in the pallet, not for specific functions.
-//! // For example, in the Balances Pallet: "Note that when using the publicly exposed functions,
-//! // you (the runtime developer) are responsible for implementing any necessary checks
-//! // (e.g. that the sender is the signer) before calling a function that will affect storage."
-//!
-//! <!-- Original author of paragraph: @AmarRSingh -->
-//!
-//! // It is up to the writer of the respective pallet (with respect to how much information to
-//! provide).
-//!
-//! \#### Public Inspection functions - Immutable (getters)
-//!
-//! // Insert a subheading for each getter function signature
-//!
-//! \##### <code>\`example_getter_name()\`</code>
-//!
-//! // What it returns
-//! // Why, when, and how often to call it
-//! // When it could panic or error
-//! // When safety issues to consider
-//!
-//! \#### Public Mutable functions (changing state)
-//!
-//! // Insert a subheading for each setter function signature
-//!
-//! \##### <code>\`example_setter_name(origin, parameter_name: T::ExampleType)\`</code>
-//!
-//! // What state it changes
-//! // Why, when, and how often to call it
-//! // When it could panic or error
-//! // When safety issues to consider
-//! // What parameter values are valid and why
-//!
-//! \### Storage Items
-//!
-//! // Explain any storage items included in this pallet
-//!
-//! \### Digest Items
-//!
-//! // Explain any digest items included in this pallet
-//!
-//! \### Inherent Data
-//!
-//! // Explain what inherent data (if any) is defined in the pallet and any other related types
-//!
-//! \### Events:
-//!
-//! // Insert events for this pallet if any
-//!
-//! \### Errors:
-//!
-//! // Explain what generates errors
-//!
-//! \## Usage
-//!
-//! // Insert 2-3 examples of usage and code snippets that show how to
-//! // use <INSERT_CUSTOM_PALLET_NAME> Pallet in a custom pallet.
-//!
-//! \### Prerequisites
-//!
-//! // Show how to include necessary imports for <INSERT_CUSTOM_PALLET_NAME> and derive
-//! // your pallet configuration trait with the `INSERT_CUSTOM_PALLET_NAME` trait.
-//!
-//! \```rust
-//! use <INSERT_CUSTOM_PALLET_NAME>;
-//!
-//! pub trait Config: <INSERT_CUSTOM_PALLET_NAME>::Config { }
-//! \```
-//!
-//! \### Simple Code Snippet
-//!
-//! // Show a simple example (e.g. how to query a public getter function of
-//! <INSERT_CUSTOM_PALLET_NAME>)
-//!
-//! \### Example from FRAME
-//!
-//! // Show a usage example in an actual runtime
-//!
-//! // See:
-//! // - Substrate TCR <https://github.com/parity-samples/substrate-tcr>
-//! // - Substrate Kitties <https://shawntabrizi.github.io/substrate-collectables-workshop/#/>

 // See the License for the specific language governing permissions and
 // limitations under the License.
 
+//! # Safe Mode
+//!
+//! Trigger for stopping all extrinsics outside of a specific whitelist.
+//!
+//! ## WARNING
+//!
+//! NOT YET AUDITED. DO NOT USE IN PRODUCTION.
+//!
+//! ## Pallet API
+//!
+//! See the [`pallet`] module for more information about the interfaces this pallet exposes,
+//! including its configuration trait, dispatchables, storage items, events, and errors.
+//!
+//! ## Overview
+//!
+//! Safe mode is entered via two paths (deposit or forced) until a set block number.
+//! The mode is exited when the block number is reached or a call to one of the exit extrinsics is
+//! made. A `WhitelistedCalls` configuration item contains all calls that can be executed while in
+//! safe mode.
+//!
+//! ### Primary Features
+//!
+//! - Entering safe mode can be via privileged origin or anyone who places a deposit.
+//! - Origin configuration items are separated for privileged entering and exiting safe mode.
+//! - A configurable duration sets the number of blocks after which the system will exit safe mode.
+//! - Safe mode may be extended beyond the configured exit by additional calls.
+//!
+//! ### Example
+//!
+//! Configuration of call filters:
+//!
+//! ```ignore
+//! impl frame_system::Config for Runtime {
+//!   // …
+//!   type BaseCallFilter = InsideBoth<DefaultFilter, SafeMode>;
+//!   // …
+//! }
+//! ```
+//!
+//! Entering safe mode with deposit:
+#![doc = docify::embed!("src/tests.rs", can_activate)]
+//!
+//! Entering safe mode via privileged origin:
+#![doc = docify::embed!("src/tests.rs", can_force_activate_with_config_origin)]
+//!
+//! Exiting safe mode via privileged origin:
+#![doc = docify::embed!("src/tests.rs", can_force_deactivate_with_config_origin)]
+//!
+//! ## Low Level / Implementation Details
+//!
+//! ### Use Cost
+//!
+//! A storage value (`EnteredUntil`) is used to store the block safe mode will be exited on.
+//! Using the call filter will require a db read of that storage on the first extrinsic.
+//! The storage will be added to the overlay and incur low cost for all additional calls.

+                  µs
+
+### Conclusions
+
+- Verification doesn't depend on ring size as verification key is already constructed.
+- The call is fast as far as the max number of tickets which can be submitted in one shot
+  is appropriately bounded.
+- Currently, the bound is set equal epoch length, which iirc for Polkadot is 3600.
+  In this case if all the tickets are submitted in one shot timing is expected to be
+  ~39 seconds, which is not acceptable. TODO: find a sensible bound
+

+## Recompute Ring Verifier Key (on epoch change)

+
+    Time ~=   1462400
+        + x    65.14
+                  µs
+
+### Conclusions
+
+- Here we load the full ring context data to recompute verification key for the epoch
+- Ring size influence is marginal (e.g. for 1500 validators → ~98 ms to be added to the base time)
+- This step is performed at most once per epoch (if validator set changes).
+- Domain size for ring context influence the PoV size (see next paragraph)
+- Decompression heavily influence timings (1.5sec vs 100ms for same domain size)

+//! Extension module for Sassafras consensus.
+//!
+//! [Sassafras](https://research.web3.foundation/Polkadot/protocols/block-production/SASSAFRAS)
+//! is a constant-time block production protocol that aims to ensure that there is
+//! exactly one block produced with constant time intervals rather than multiple or none.
+//!
+//! We run a lottery to distribute block production slots in an epoch and to fix the
+//! order validators produce blocks in, by the beginning of an epoch.
+//!
+//! Each validator signs the same VRF input and publishes the output on-chain. This
+//! value is their lottery ticket that can be validated against their public key.
+//!
+//! We want to keep lottery winners secret, i.e. do not publish their public keys.
+//! At the beginning of the epoch all the validators tickets are published but not
+//! their public keys.
+//!
+//! A valid tickets is validated when an honest validator reclaims it on block
+//! production.
+//!
+//! To prevent submission of fake tickets, resulting in empty slots, the validator
+//! when submitting the ticket accompanies it with a SNARK of the statement: "Here's
+//! my VRF output that has been generated using the given VRF input and my secret
+//! key. I'm not telling you my keys, but my public key is among those of the
+//! nominated validators", that is validated before the lottery.
+//!
+//! To anonymously publish the ticket to the chain a validator sends their tickets
+//! to a random validator who later puts it on-chain as a transaction.

+//! This crate is an amalgamation of multiple other crates that are often used together to compose a
+//! pallet. It is not necessary to use it, and it may fall short for certain purposes.
+//!
+//! In short, this crate only re-exports types and traits from multiple sources. All of these
+//! sources are listed (and re-exported again) in [`deps`].

+# Changelog
+
+All notable changes and migrations to pallet-staking will be documented in this file.
+
+The format is loosely based
+on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/). We maintain a
+single integer version number for staking pallet to keep track of all storage
+migrations.
+
+## [v14]
+
+### Added
+
+- New item `ErasStakersPaged` that keeps up to `MaxExposurePageSize`
+  individual nominator exposures by era, validator and page.
+- New item `ErasStakersOverview` complementary to `ErasStakersPaged` which keeps
+  state of own and total stake of the validator across pages.
+- New item `ClaimedRewards` to support paged rewards payout.
+
+### Deprecated
+
+- `ErasStakers` and `ErasStakersClipped` is deprecated, will not be used any longer for the exposures of the new era
+  post v14 and can be removed after 84 eras once all the exposures are stale.
+- Field `claimed_rewards` in item `Ledger` is renamed
+  to `legacy_claimed_rewards` and can be removed after 84 eras.

+//! A Ledger implementation for stakers.
+//!
+//! A [`StakingLedger`] encapsulates all the state and logic related to the stake of bonded
+//! stakers, namely, it handles the following storage items:
+//! * [`Bonded`]: mutates and reads the state of the controller <> stash bond map (to be deprecated
+//! soon);
+//! * [`Ledger`]: mutates and reads the state of all the stakers. The [`Ledger`] storage item stores
+//!   instances of [`StakingLedger`] keyed by the staker's controller account and should be mutated
+//!   and read through the [`StakingLedger`] API;
+//! * [`Payee`]: mutates and reads the reward destination preferences for a bonded stash.
+//! * Staking locks: mutates the locks for staking.
+//!
+//! NOTE: All the storage operations related to the staking ledger (both reads and writes) *MUST* be
+//! performed through the methods exposed by the [`StakingLedger`] implementation in order to ensure
+//! state consistency.

-/// ```
-///
-/// I.e. it must be a type alias, with generics: `T` or `T: Config`. The aliased type must be
-/// one of `StorageValue`, `StorageMap` or `StorageDoubleMap`. The generic arguments of the
-/// storage type can be given in two manners: named and unnamed. For named generic arguments,
-/// the name for each argument should match the name defined for it on the storage struct:
-/// * `StorageValue` expects `Value` and optionally `QueryKind` and `OnEmpty`,
-/// * `StorageMap` expects `Hasher`, `Key`, `Value` and optionally `QueryKind` and `OnEmpty`,
-/// * `CountedStorageMap` expects `Hasher`, `Key`, `Value` and optionally `QueryKind` and `OnEmpty`,
-/// * `StorageDoubleMap` expects `Hasher1`, `Key1`, `Hasher2`, `Key2`, `Value` and optionally
-///   `QueryKind` and `OnEmpty`.
-///
-/// For unnamed generic arguments: Their first generic must be `_` as it is replaced by the
-/// macro and other generic must declared as a normal generic type declaration.
-///
-/// The `Prefix` generic written by the macro is generated using
-/// `PalletInfo::name::<Pallet<..>>()` and the name of the storage type. E.g. if runtime names
-/// the pallet "MyExample" then the storage `type Foo<T> = ...` should use the prefix:
-/// `Twox128(b"MyExample") ++ Twox128(b"Foo")`.
-///
-/// For the `CountedStorageMap` variant, the `Prefix` also implements
-/// `CountedStorageMapInstance`. It also associates a `CounterPrefix`, which is implemented the
-/// same as above, but the storage prefix is prepend with `"CounterFor"`. E.g. if runtime names
-/// the pallet "MyExample" then the storage `type Foo<T> = CountedStorageaMap<...>` will store
-/// its counter at the prefix: `Twox128(b"MyExample") ++ Twox128(b"CounterForFoo")`.

+	/// - The dispatchable must declare its index via [`call_index`], which can override the
+	///   position of a function in `enum Call`.
+	/// - The first argument is always an `OriginFor` (or `T::RuntimeOrigin`).
+	/// - The return type is always [`crate::dispatch::DispatchResult`] (or

+	/// defined call index. The dispatchable function that lexically follows the function with
+	/// a defined call index will have that call index, but incremented by 1, e.g. if there are
+	/// 3 dispatchable functions `fn foo`, `fn bar` and `fn qux` in that order, and only `fn

+	///
+	/// > From the perspective of this pallet, the entire blockchain state is abstracted behind
+	/// > a key-value api, namely [`sp_io::storage`].
+	///
+	/// ## Storage Types
+	///
+	/// The following storage types are supported by the `#[storage]` macro. For specific
+	/// information about each storage type, refer to the documentation of the respective type.
+	///
+	/// * [`StorageValue`](crate::storage::types::StorageValue)
+	/// * [`StorageMap`](crate::storage::types::StorageMap)
+	/// * [`CountedStorageMap`](crate::storage::types::CountedStorageMap)
+	/// * [`StorageDoubleMap`](crate::storage::types::StorageDoubleMap)
+	/// * [`StorageNMap`](crate::storage::types::StorageNMap)
+	/// * [`CountedStorageNMap`](crate::storage::types::CountedStorageNMap)
+	///
+	/// ## Storage Type Usage
+	///
+	/// The following details are relevant to all of the aforementioned storage types.
+	/// Depending on the exact storage type, it may require the following generic parameters:
+	///
+	/// * [`Prefix`](#prefixes) - Used to give the storage item a unique key in the underlying
+	///   storage.
+	/// * `Key` - Type of the keys used to store the values,
+	/// * `Value` - Type of the value being stored,
+	/// * [`Hasher`](#hashers) - Used to ensure the keys of a map are uniformly distributed,
+	/// * [`QueryKind`](#querykind) - Used to configure how to handle queries to the underlying
+	///   storage,
+	/// * `OnEmpty` - Used to handle missing values when querying the underlying storage,
+	/// * `MaxValues` - _not currently used_.
+	///
+	/// Each `Key` type requires its own designated `Hasher` declaration, so that
+	/// [`StorageDoubleMap`](frame_support::storage::types::StorageDoubleMap) needs two of
+	/// each, and [`StorageNMap`](frame_support::storage::types::StorageNMap) needs `N` such
+	/// pairs. Since [`StorageValue`](frame_support::storage::types::StorageValue) only stores
+	/// a single element, no configuration of hashers is needed.
+	///
+	/// ### Syntax
+	///
+	/// Two general syntaxes are supported, as demonstrated below:
+	///
+	/// 1. Named type parameters, e.g., `type Foo<T> = StorageValue<Value = u32>`.
+	/// 2. Positional type parameters, e.g., `type Foo<T> = StorageValue<_, u32>`.
+	///
+	/// In both instances, declaring the generic parameter `<T>` is mandatory. Optionally, it
+	/// can also be explicitly declared as `<T: Config>`. In the compiled code, `T` will
+	/// automatically include the trait bound `Config`.
+	///
+	/// Note that in positional syntax, the first generic type parameter must be `_`.
+	///
+	/// #### Example
+	///
+	/// ```
+	/// #[frame_support::pallet]
+	/// mod pallet {
+	///     # use frame_support::pallet_prelude::*;
+	///     # #[pallet::config]
+	///     # pub trait Config: frame_system::Config {}
+	///     # #[pallet::pallet]
+	///     # pub struct Pallet<T>(_);
+	///     /// Positional syntax, without bounding `T`.
+	///     #[pallet::storage]
+	///     pub type Foo<T> = StorageValue<_, u32>;
+	///
+	///     /// Positional syntax, with bounding `T`.
+	///     #[pallet::storage]
+	///     pub type Bar<T: Config> = StorageValue<_, u32>;
+	///
+	///     /// Named syntax.
+	///     #[pallet::storage]
+	///     pub type Baz<T> = StorageMap<Hasher = Blake2_128Concat, Key = u32, Value = u32>;
+	/// }
+	/// ```
+	///
+	/// ### QueryKind
+	///
+	/// Every storage type mentioned above has a generic type called
+	/// [`QueryKind`](frame_support::storage::types::QueryKindTrait) that determines its
+	/// "query" type. This refers to the kind of value returned when querying the storage, for
+	/// instance, through a `::get()` method.
+	///
+	/// There are three types of queries:
+	///
+	/// 1. [`OptionQuery`](frame_support::storage::types::OptionQuery): The default query type.
+	///    It returns `Some(V)` if the value is present, or `None` if it isn't, where `V` is
+	///    the value type.
+	/// 2. [`ValueQuery`](frame_support::storage::types::ValueQuery): Returns the value itself
+	///    if present; otherwise, it returns `Default::default()`. This behavior can be
+	///    adjusted with the `OnEmpty` generic parameter, which defaults to `OnEmpty =
+	///    GetDefault`.
+	/// 3. [`ResultQuery`](frame_support::storage::types::ResultQuery): Returns `Result<V, E>`,
+	///    where `V` is the value type.
+	///
+	/// See [`QueryKind`](frame_support::storage::types::QueryKindTrait) for further examples.
+	///
+	/// ### Optimized Appending
+	///
+	/// All storage items — such as
+	/// [`StorageValue`](frame_support::storage::types::StorageValue),
+	/// [`StorageMap`](frame_support::storage::types::StorageMap), and their variants—offer an
+	/// `::append()` method optimized for collections. Using this method avoids the
+	/// inefficiency of decoding and re-encoding entire collections when adding items. For
+	/// instance, consider the storage declaration `type MyVal<T> = StorageValue<_, Vec<u8>,
+	/// ValueQuery>`. With `MyVal` storing a large list of bytes, `::append()` lets you
+	/// directly add bytes to the end in storage without processing the full list. Depending on
+	/// the storage type, additional key specifications may be needed.
+	///
+	/// #### Example
+	#[doc = docify::embed!("src/lib.rs", example_storage_value_append)]
+	/// Similarly, there also exists a `::try_append()` method, which can be used when handling
+	/// types where an append operation might fail, such as a
+	/// [`BoundedVec`](frame_support::BoundedVec).
+	///
+	/// #### Example
+	#[doc = docify::embed!("src/lib.rs", example_storage_value_try_append)]
+	/// ### Optimized Length Decoding
+	///
+	/// All storage items — such as
+	/// [`StorageValue`](frame_support::storage::types::StorageValue),
+	/// [`StorageMap`](frame_support::storage::types::StorageMap), and their counterparts —
+	/// incorporate the `::decode_len()` method. This method allows for efficient retrieval of
+	/// a collection's length without the necessity of decoding the entire dataset.
+	/// #### Example
+	#[doc = docify::embed!("src/lib.rs", example_storage_value_decode_len)]
+	/// ### Hashers
+	///
+	/// For all storage types, except
+	/// [`StorageValue`](frame_support::storage::types::StorageValue), a set of hashers needs
+	/// to be specified. The choice of hashers is crucial, especially in production chains. The
+	/// purpose of storage hashers in maps is to ensure the keys of a map are
+	/// uniformly distributed. An unbalanced map/trie can lead to inefficient performance.
+	///
+	/// In general, hashers are categorized as either cryptographically secure or not. The
+	/// former is slower than the latter. `Blake2` and `Twox` serve as examples of each,
+	/// respectively.
+	///
+	/// As a rule of thumb:
+	///
+	/// 1. If the map keys are not controlled by end users, or are cryptographically secure by
+	/// definition (e.g., `AccountId`), then the use of cryptographically secure hashers is NOT
+	/// required.
+	/// 2. If the map keys are controllable by the end users, cryptographically secure hashers
+	/// should be used.
+	///
+	/// For more information, look at the types that implement
+	/// [`frame_support::StorageHasher`](frame_support::StorageHasher).
+	///
+	/// Lastly, it's recommended for hashers with "concat" to have reversible hashes. Refer to
+	/// the implementors section of
+	/// [`hash::ReversibleStorageHasher`](frame_support::hash::ReversibleStorageHasher).
+	///
+	/// ### Prefixes
+	///
+	/// Internally, every storage type generates a "prefix". This prefix serves as the initial
+	/// segment of the key utilized to store values in the on-chain state (i.e., the final key
+	/// used in [`sp_io::storage`](sp_io::storage)). For all storage types, the following rule
+	/// applies:
+	///
+	/// > The storage prefix begins with `twox128(pallet_prefix) ++ twox128(STORAGE_PREFIX)`,
+	/// > where
+	/// > `pallet_prefix` is the name assigned to the pallet instance in
+	/// > [`frame_support::construct_runtime`](frame_support::construct_runtime), and
+	/// > `STORAGE_PREFIX` is the name of the `type` aliased to a particular storage type, such
+	/// > as
+	/// > `Foo` in `type Foo<T> = StorageValue<..>`.
+	///
+	/// For [`StorageValue`](frame_support::storage::types::StorageValue), no additional key is
+	/// required. For map types, the prefix is extended with one or more keys defined by the
+	/// map.
+	///
+	/// #### Example
+	#[doc = docify::embed!("src/lib.rs", example_storage_value_map_prefixes)]
+	/// ## Related Macros
+	///
+	/// The following attribute macros can be used in conjunction with the `#[storage]` macro:
+	///
+	/// * [`macro@getter`]: Creates a custom getter function.
+	/// * [`macro@storage_prefix`]: Overrides the default prefix of the storage item.
+	/// * [`macro@unbounded`]: Declares the storage item as unbounded.
+	///
+	/// #### Example
+	/// ```
+	/// #[frame_support::pallet]
+	/// mod pallet {
+	///     # use frame_support::pallet_prelude::*;
+	///     # #[pallet::config]
+	///     # pub trait Config: frame_system::Config {}
+	///     # #[pallet::pallet]
+	///     # pub struct Pallet<T>(_);
+	/// 	/// A kitchen-sink StorageValue, with all possible additional attributes.
+	///     #[pallet::storage]
+	/// 	#[pallet::getter(fn foo)]
+	/// 	#[pallet::storage_prefix = "OtherFoo"]
+	/// 	#[pallet::unbounded]
+	///     pub type Foo<T> = StorageValue<_, u32, ValueQuery>;
+	/// }
+	/// ```

-//! # Timestamp Pallet
-//!
-//! The Timestamp pallet provides functionality to get and set the on-chain time.
-//!
-//! - [`Config`]
-//! - [`Call`]
-//! - [`Pallet`]
-//!
-//! ## Overview
-//!
-//! The Timestamp pallet allows the validators to set and validate a timestamp with each block.
-//!
-//! It uses inherents for timestamp data, which is provided by the block author and
-//! validated/verified by other validators. The timestamp can be set only once per block and must be
-//! set each block. There could be a constraint on how much time must pass before setting the new
-//! timestamp.
-//!
-//! **NOTE:** The Timestamp pallet is the recommended way to query the on-chain time instead of
-//! using an approach based on block numbers. The block number based time measurement can cause
-//! issues because of cumulative calculation errors and hence should be avoided.
+//! > Made with *Substrate*, for *Polkadot*.
 //!
-//! ## Interface
+//! [![github]](https://github.com/paritytech/polkadot-sdk/substrate/frame/timestamp)

+//! # Timestamp Pallet
 //!
-//! ### Public functions
+//! A pallet that provides a way for consensus systems to set and check the onchain time.
 //!
-//! * `get` - Gets the current time for the current block. If this function is called prior to
-//! setting the timestamp, it will return the timestamp of the previous block.
+//! ## Pallet API
 //!
-//! ### Config Getters
+//! See the [`pallet`] module for more information about the interfaces this pallet exposes,
+//! including its configuration trait, dispatchables, storage items, events and errors.
 //!
-//! * `MinimumPeriod` - Gets the minimum (and advised) period between blocks for the chain.
+//! ## Overview
 //!
-//! ## Usage
+//! The Timestamp pallet is designed to create a consensus-based time source. This helps ensure that
+//! nodes maintain a synchronized view of time that all network participants can agree on.
 //!
-//! The following example shows how to use the Timestamp pallet in your custom pallet to query the
-//! current timestamp.
+//! It defines an _acceptable range_ using a configurable constant to specify how much time must
+//! pass before setting the new timestamp. Validator nodes in the network must verify that the
+//! timestamp falls within this acceptable range and reject blocks that do not.
 //!
-//! ### Prerequisites
+//! > **Note:** The timestamp set by this pallet is the recommended way to query the onchain time
+//! > instead of using block numbers alone. Measuring time with block numbers can cause cumulative
+//! > calculation errors if depended upon in time critical operations and hence should generally be
+//! > avoided.
 //!
-//! Import the Timestamp pallet into your custom pallet and derive the pallet configuration
-//! trait from the timestamp trait.
+//! ## Example
 //!
-//! ### Get current timestamp
+//! To get the current time for the current block in another pallet:
 //!
 //! ```
 //! use pallet_timestamp::{self as timestamp};

+//! ## Low Level / Implementation Details
 //!
-//! ## Related Pallets
+//! A timestamp is added to the chain using an _inherent extrinsic_ that only a block author can
+//! submit. Inherents are a special type of extrinsic in Substrate chains that will always be
+//! included in a block.
 //!
-//! * [Session](../pallet_session/index.html)
-
+//! To provide inherent data to the runtime, this pallet implements
+//! [`ProvideInherent`](frame_support::inherent::ProvideInherent). It will only create an inherent
+//! if the [`Call::set`] dispatchable is called, using the
+//! [`inherent`](frame_support::pallet_macros::inherent) macro which enables validator nodes to call
+//! into the runtime to check that the timestamp provided is valid.
+//! The implementation of [`ProvideInherent`](frame_support::inherent::ProvideInherent) specifies a
+//! constant called `MAX_TIMESTAMP_DRIFT_MILLIS` which is used to determine the acceptable range for
+//! a valid timestamp. If a block author sets a timestamp to anything that is more than this
+//! constant, a validator node will reject the block.
+//!
+//! The pallet also ensures that a timestamp is set at the start of each block by running an
+//! assertion in the `on_finalize` runtime hook. See [`frame_support::traits::Hooks`] for more
+//! information about how hooks work.
+//!
+//! Because inherents are applied to a block in the order they appear in the runtime
+//! construction, the index of this pallet in
+//! [`construct_runtime`](frame_support::construct_runtime) must always be less than any other
+//! pallet that depends on it.
+//!
+//! The [`Config::OnTimestampSet`] configuration trait can be set to another pallet we want to
+//! notify that the timestamp has been updated, as long as it implements [`OnTimestampSet`].
+//! Examples are the Babe and Aura pallets.
+//! This pallet also implements [`Time`] and [`UnixTime`] so it can be used to configure other
+//! pallets that require these types (e.g. in Staking pallet).
+//!
+//! ## Panics
+//!
+//! There are 3 cases where this pallet could cause the runtime to panic.
+//!
+//! 1. If no timestamp is set at the end of a block.
+//!
+//! 2. If a timestamp is set more than once per block:
+#![doc = docify::embed!("src/tests.rs", double_timestamp_should_fail)]
+//!
+//! 3. If a timestamp is set before the [`Config::MinimumPeriod`] is elapsed:
+#![doc = docify::embed!("src/tests.rs", block_period_minimum_enforced)]
+#![deny(missing_docs)]

+//! # Skip Feeless Payment Pallet
+//!
+//! This pallet allows runtimes that include it to skip payment of transaction fees for
+//! dispatchables marked by [`#[pallet::feeless_if]`](`macro@
+//! frame_support::pallet_prelude::feeless_if`).
+//!
+//! ## Overview
+//!
+//! It does this by wrapping an existing [`SignedExtension`] implementation (e.g.
+//! [`pallet-transaction-payment`]) and checking if the dispatchable is feeless before applying the
+//! wrapped extension. If the dispatchable is indeed feeless, the extension is skipped and a custom
+//! event is emitted instead. Otherwise, the extension is applied as usual.
+//!
+//!
+//! ## Integration
+//!
+//! This pallet wraps an existing transaction payment pallet. This means you should both pallets
+//! in your `construct_runtime` macro and include this pallet's
+//! [`SignedExtension`] ([`SkipCheckIfFeeless`]) that would accept the existing one as an argument.

 //! # Treasury Pallet
 //!
 //! The Treasury pallet provides a "pot" of funds that can be managed by stakeholders in the system
 //! and a structure for making spending proposals from this pot.
 //!
-//! - [`Config`]
-//! - [`Call`]
-//!
 //! ## Overview
 //!
 //! The Treasury Pallet itself provides the pot to store funds, and a means for stakeholders to
-//! propose, approve, and deny expenditures. The chain will need to provide a method (e.g.
-//! inflation, fees) for collecting funds.
+//! propose and claim expenditures (aka spends). The chain will need to provide a method to approve
+//! spends (e.g. public referendum) and a method for collecting funds (e.g. inflation, fees).
 //!
-//! By way of example, the Council could vote to fund the Treasury with a portion of the block
+//! By way of example, stakeholders could vote to fund the Treasury with a portion of the block
 //! reward and use the funds to pay developers.
 //!
-//!
 //! ### Terminology
 //!
 //! - **Proposal:** A suggestion to allocate funds from the pot to a beneficiary.
 //! - **Beneficiary:** An account who will receive the funds from a proposal iff the proposal is
 //!   approved.
-//! - **Deposit:** Funds that a proposer must lock when making a proposal. The deposit will be
-//!   returned or slashed if the proposal is approved or rejected respectively.
 //! - **Pot:** Unspent funds accumulated by the treasury pallet.
+//! - **Spend** An approved proposal for transferring a specific amount of funds to a designated
+//!   beneficiary.
+//!
+//! ### Example
 //!
-//! ## Interface
+//! 1. Multiple local spends approved by spend origins and received by a beneficiary.
+#![doc = docify::embed!("src/tests.rs", spend_local_origin_works)]
 //!
-//! ### Dispatchable Functions
+//! 2. Approve a spend of some asset kind and claim it.
+#![doc = docify::embed!("src/tests.rs", spend_payout_works)]
 //!
-//! General spending/proposal protocol:
-//! - `propose_spend` - Make a spending proposal and stake the required deposit.
-//! - `reject_proposal` - Reject a proposal, slashing the deposit.
-//! - `approve_proposal` - Accept the proposal, returning the deposit.
-//! - `remove_approval` - Remove an approval, the deposit will no longer be returned.
+//! ## Pallet API
 //!
-//! ## GenesisConfig
+//! See the [`pallet`] module for more information about the interfaces this pallet exposes,
+//! including its configuration trait, dispatchables, storage items, events and errors.
 //!
-//! The Treasury pallet depends on the [`GenesisConfig`].
+//! ## Low Level / Implementation Details
+//!
+//! Spends can be initiated using either the `spend_local` or `spend` dispatchable. The
+//! `spend_local` dispatchable enables the creation of spends using the native currency of the
+//! chain, utilizing the funds stored in the pot. These spends are automatically paid out every
+//! [`pallet::Config::SpendPeriod`]. On the other hand, the `spend` dispatchable allows spending of
+//! any asset kind managed by the treasury, with payment facilitated by a designated
+//! [`pallet::Config::Paymaster`]. To claim these spends, the `payout` dispatchable should be called
+//! within some temporal bounds, starting from the moment they become valid and within one
+//! [`pallet::Config::PayoutPeriod`].

+//! # Transaction Pause
+//!
+//! Allows dynamic, chain-state-based pausing and unpausing of specific extrinsics via call filters.
+//!
+//! ## WARNING
+//!
+//! NOT YET AUDITED. DO NOT USE IN PRODUCTION.
+//!
+//! ## Pallet API
+//!
+//! See the [`pallet`] module for more information about the interfaces this pallet exposes,
+//! including its configuration trait, dispatchables, storage items, events, and errors.
+//!
+//! ## Overview
+//!
+//! A dynamic call filter that can be controlled with extrinsics.
+//!
+//! Pausing an extrinsic means that the extrinsic CANNOT be called again until it is unpaused.
+//! The exception is calls that use `dispatch_bypass_filter`, typically only with the root origin.
+//!
+//! ### Primary Features
+//!
+//! - Calls that should never be paused can be added to a whitelist.
+//! - Separate origins are configurable for pausing and pausing.
+//! - Pausing is triggered using the string representation of the call.
+//! - Pauses can target a single extrinsic or an entire pallet.
+//! - Pauses can target future extrinsics or pallets.
+//!
+//! ### Example
+//!
+//! Configuration of call filters:
+//!
+//! ```ignore
+//! impl frame_system::Config for Runtime {
+//!   // …
+//!   type BaseCallFilter = InsideBoth<DefaultFilter, TxPause>;
+//!   // …
+//! }
+//! ```
+//!
+//! Pause specific all:
+#![doc = docify::embed!("src/tests.rs", can_pause_specific_call)]
+//!
+//! Unpause specific all:
+#![doc = docify::embed!("src/tests.rs", can_unpause_specific_call)]
+//!
+//! Pause all calls in a pallet:
+#![doc = docify::embed!("src/tests.rs", can_pause_all_calls_in_pallet_except_on_whitelist)]
+//!
+//! ## Low Level / Implementation Details
+//!
+//! ### Use Cost
+//!
+//! A storage map (`PausedCalls`) is used to store currently paused calls.
+//! Using the call filter will require a db read of that storage on each extrinsic.

-//! The main elliptic curves trait, allowing Substrate to call into host functions
-//! for operations on elliptic curves.
+//! This crate offers elliptic curves types which are compatible with the
+//! [Arkworks](https://github.com/arkworks-rs) library functionalities.
+//!
+//! The implementation has been primarily designed to be used in slow hosted
+//! targets (e.g. wasm32) and offloads the most computationally expensive
+//! operations to the host by leveraging the
+//! [arkworks-extensions](https://github.com/paritytech/arkworks-extensions)
+//! library and Substrate's host functions.
+//!
+//! The exported types are organized and named in a way that mirrors the structure
+//! of the types in the original Arkworks library. This design choice aims to make
+//! it easier for users already familiar with the library to understand and utilize
+//! the exported types effectively.

-//! # Substrate
-//!
-//! Substrate is a Rust framework for building blockchains in a modular and extensible way. While in
-//! itself un-opinionated, it is the main engine behind the Polkadot ecosystem.
-//!
-//! [![github]](https://github.com/paritytech/substrate/) - [![polkadot]](https://polkadot.network)
-//!
-//! This crate in itself does not contain any code and is just meant ot be a documentation hub for
-//! substrate-based crates.
-//!
-//! ## Overview
-//!
-//! Substrate approaches blockchain development with an acknowledgement of a few self-evident
-//! truths:
-//!
-//! 1. Society and technology evolves.
-//! 2. Humans are fallible.
-//!
-//! This, specifically, makes the task of designing a correct, safe and long-lasting blockchain
-//! system hard.
-//!
-//! Nonetheless, in order to achieve this goal, substrate embraces the following:
-//!
-//! 1. Use of **Rust** as a modern, and safe programming language, which limits human error through
-//!    various means, most notably memory safety.
-//! 2. Substrate is written from the ground-up with a generic, modular and extensible design. This
-//!    ensures that software components can be easily swapped and upgraded. Examples of this is
-//!    multiple consensus mechanisms provided by Substrate, as listed below.
-//! 3. Lastly, the final blockchain system created with the above properties needs to be
-//!    upgradeable. In order to achieve this, Substrate is designed as a meta-protocol, whereby the
-//!    application logic of the blockchain (called "Runtime") is encoded as a Wasm blob, and is
-//!    stored onchain. The rest of the system (called "Client") acts as the executor of the Wasm
-//!    blob.
-//!
-//! In essence, the meta-protocol of all Substrate based chains is the "Runtime as Wasm blob"
-//! accord. This enables the Runtime to become inherently upgradeable (without forks). The upgrade
-//! is merely a matter of the Wasm blob being changed in the chain state, which is, in principle,
-//! same as updating an account's balance.
-//!
-//! To learn more about the substrate architecture using some visuals, see [`substrate_diagram`].
-//!
-//! `FRAME`, Substrate's default runtime development library takes the above even further by
-//! embracing a declarative programming model whereby correctness is enhanced and the system is
-//! highly configurable through parameterization.
-//!
-//! All in all, this design enables all substrate-based chains to achieve forkless, self-enacting
-//! upgrades out of the box. Combined with governance abilities that are shipped with `FRAME`, this
-//! enables a chain to survive the test of time.
-//!
-//! ## How to Get Stared
-//!
-//! Most developers want to leave the client side code as-is, and focus on the runtime. To do so,
-//! look into the [`frame_support`] crate, which is the entry point crate into runtime development
-//! with FRAME.
-//!
-//! > Side note, it is entirely possible to craft a substrate-based runtime without FRAME, an
-//! > example of which can be found [here](https://github.com/JoshOrndorff/frameless-node-template).
-//!
-//! In more broad terms, the following avenues exist into developing with substrate:
-//!
-//! * **Templates**: A number of substrate-based templates exist and they can be used for various
-//!   purposes, with zero to little additional code needed. All of these templates contain runtimes
-//!   that are highly configurable and are likely suitable for basic needs.
-//! * `FRAME`: If need, one can customize that runtime even further, by using `FRAME` and developing
-//!   custom modules.
-//! * **Core**: To the contrary, some developers may want to customize the client side software to
-//!   achieve novel goals such as a new consensus engine, or a new database backend. While
-//!   Substrate's main configurability is in the runtime, the client is also highly generic and can
-//!   be customized to a great extent.
-//!
-//! ## Structure
-//!
-//! Substrate is a massive cargo workspace with hundreds of crates, therefore it is useful to know
-//! how to navigate its crates.
-//!
-//! In broad terms, it is divided into three categories:
-//!
-//! * `sc-*` (short for *substrate-client*) crates, located under `./client` folder. These are all
-//!   the client crates. Notable examples are crates such as [`sc-network`], various consensus
-//!   crates, [`sc-rpc-api`] and [`sc-client-db`], all of which are expected to reside in the client
-//!   side.
-//! * `sp-*` (short for *substrate-primitives*) crates, located under `./primitives` folder. These
-//!   are the traits that glue the client and runtime together, but are not opinionated about what
-//!   framework is using for building the runtime. Notable examples are [`sp-api`] and [`sp-io`],
-//!   which form the communication bridge between the client and runtime, as explained in
-//!   [`substrate_diagram`].
-//! * `pallet-*` and `frame-*` crates, located under `./frame` folder. These are the crates related
-//!   to FRAME. See [`frame_support`] for more information.
-//!
-//! ### Wasm Build
-//!
-//! Many of the Substrate crates, such as entire `sp-*`, need to compile to both Wasm (when a Wasm
-//! runtime is being generated) and native (for example, when testing). To achieve this, Substrate
-//! follows the convention of the Rust community, and uses a `feature = "std"` to signify that a
-//!  crate is being built with the standard library, and is built for native. Otherwise, it is built
-//!  for `no_std`.
-//!
-//! This can be summarized in `#![cfg_attr(not(feature = "std"), no_std)]`, which you can often find
-//! in any Substrate-based runtime.
-//!
-//! Substrate-based runtimes use [`substrate-wasm-builder`] in their `build.rs` to automatically
-//! build their Wasm files as a part of normal build commandsOnce built, the wasm file is placed in
-//! `./target/{debug|release}/wbuild/{runtime_name}.wasm`.
-//!
-//! ### Binaries
-//!
-//! Multiple binaries are shipped with substrate, the most important of which are located in the
-//! `./bin` folder.
-//!
-//! * [`node`] is an extensive substrate node that contains the superset of all runtime and client
-//!   side features. The corresponding runtime, called [`kitchensink_runtime`] contains all of the
-//!   modules that are provided with `FRAME`. This node and runtime is only used for testing and
-//!   demonstration.
-//!     * [`chain-spec-builder`]: Utility to build more detailed chain-specs for the aforementioned
-//!       node. Other projects typically contain a `build-spec` subcommand that does the same.
-//! * [`node-template`]: a template node that contains a minimal set of features and can act as a
-//!   starting point of a project.
-//! * [`subkey`]: Substrate's key management utility.
-//!
-//! ### Anatomy of a Binary Crate
-//!
-//! From the above, [`node`] and [`node-template`] are essentially blueprints of a substrate-based
-//! project, as the name of the latter is implying. Each substrate-based project typically contains
-//! the following:
-//!
-//! * Under `./runtime`, a `./runtime/src/lib.rs` which is the top level runtime amalgamator file.
-//!   This file typically contains the [`frame_support::construct_runtime`] macro, which is the
-//!   final definition of a runtime.
-//!
-//! * Under `./node`, a `main.rs`, which is the point, and a `./service.rs`, which contains all the
-//!   client side components. Skimming this file yields an overview of the networking, database,
-//!   consensus and similar client side components.
-//!
-//! > The above two are conventions, not rules.
-//!
-//! ## Parachain?
-//!
-//! As noted above, Substrate is the main engine behind the Polkadot ecosystem. One of the ways
-//! through which Polkadot can be utilized is by building "parachains", blockchains that are
-//! connected to Polkadot's shared security.
-//!
-//! To build a parachain, one could use [`Cumulus`](https://github.com/paritytech/cumulus/), the
-//! library on top of Substrate, empowering any substrate-based chain to be a Polkadot parachain.
-//!
-//! ## Where To Go Next?
-//!
-//! Additional noteworthy crates within substrate:
-//!
-//! - RPC APIs of a Substrate node: [`sc-rpc-api`]/[`sc-rpc`]

-/// In this module, we explore substrate at a more depth. First, let's establish substrate being
-/// divided into a client and runtime.
-///
-/// ```mermaid
-/// graph TB
-/// subgraph Substrate
-/// 	direction LR
-/// 	subgraph Client
-/// 	end
-/// 	subgraph Runtime
-/// 	end
-/// end
-/// ```
-///
-/// The client and the runtime of course need to communicate. This is done through two concepts:
-///
-/// 1. Host functions: a way for the (Wasm) runtime to talk to the client. All host functions are
-///    defined in [`sp-io`]. For example, [`sp-io::storage`] are the set of host functions that
-///    allow the runtime to read and write data to the on-chain state.
-/// 2. Runtime APIs: a way for the client to talk to the Wasm runtime. Runtime APIs are defined
-///    using macros and utilities in [`sp-api`]. For example, [`sp-api::Core`] is the most basic
-///    runtime API that any blockchain must implement in order to be able to (re) execute blocks.
-///
-/// ```mermaid
-/// graph TB
-/// subgraph Substrate
-/// 	direction LR
-/// 	subgraph Client
-/// 	end
-/// 	subgraph Runtime
-/// 	end
-/// 	Client --runtime-api--> Runtime
-/// 	Runtime --host-functions--> Client
-/// end
-/// ```
-///
-/// Finally, let's expand the diagram a bit further and look at the internals of each component:
-///
-/// ```mermaid
-/// graph TB
-/// subgraph Substrate
-/// 	direction LR
-/// 	subgraph Client
-/// 		Database
-/// 		Networking
-/// 		Consensus
-/// 	end
-/// 	subgraph Runtime
-/// 		subgraph FRAME
-/// 			direction LR
-/// 			Governance
-/// 			Currency
-/// 			Staking
-/// 			Identity
-/// 		end
-/// 	end
-/// 	Client --runtime-api--> Runtime
-/// 	Runtime --host-functions--> Client
-/// end
-/// ```
-///
-/// As noted the runtime contains all of the application specific logic of the blockchain. This is
-/// usually written with `FRAME`. The client, on the other hand, contains reusable and generic
-/// components that are not specific to one single blockchain, such as networking, database, and the
-/// consensus engine.
-///

-# Wasm builder is a utility for building a project as a Wasm binary
-
-The Wasm builder is a tool that integrates the process of building the WASM binary of your project into the main `cargo`
-build process.
-
-## Project setup
-
-A project that should be compiled as a Wasm binary needs to:
-
-1. Add a `build.rs` file.
-2. Add `wasm-builder` as dependency into `build-dependencies` (can be made optional and only enabled when `std` feature
-   is used).
-
-The `build.rs` file needs to contain the following code:
-
-```rust
-fn main() {
-    #[cfg(feature = "std")]
-    {
-        substrate_wasm_builder::WasmBuilder::new()
-            // Tell the builder to build the project (crate) this `build.rs` is part of.
-            .with_current_project()
-            // Make sure to export the `heap_base` global, this is required by Substrate
-            .export_heap_base()
-            // Build the Wasm file so that it imports the memory (need to be provided by at instantiation)
-            .import_memory()
-            // Build it.
-            .build();
-    }
-}
-```
-
-As the final step, you need to add the following to your project:
-
-```rust
-include!(concat!(env!("OUT_DIR"), "/wasm_binary.rs"));
-```
-
-This will include the generated Wasm binary as two constants `WASM_BINARY` and `WASM_BINARY_BLOATY`. The former is a
-compact Wasm binary and the latter is the Wasm binary as being generated by the compiler. Both variables have
-`Option<&'static [u8]>` as type.
-
-### Features
-
-Wasm builder supports to enable cargo features while building the Wasm binary. By default it will enable all features in
-the wasm build that are enabled for the native build except the `default` and `std` features. Besides that, wasm builder
-supports the special `runtime-wasm` feature. This `runtime-wasm` feature will be enabled by the wasm builder when it
-compiles the Wasm binary. If this feature is not present, it will not be enabled.
-
-## Environment variables
-
-By using environment variables, you can configure which Wasm binaries are built and how:
-
-- `SKIP_WASM_BUILD` - Skips building any Wasm binary. This is useful when only native should be recompiled. If this is
-                      the first run and there doesn't exist a Wasm binary, this will set both variables to `None`.
-- `WASM_BUILD_TYPE` - Sets the build type for building Wasm binaries. Supported values are `release` or `debug`. By
-                      default the build type is equal to the build type used by the main build.
-- `FORCE_WASM_BUILD` - Can be set to force a Wasm build. On subsequent calls the value of the variable needs to change.
-                       As wasm-builder instructs `cargo` to watch for file changes this environment variable should only
-                       be required in certain circumstances.
-- `WASM_BUILD_RUSTFLAGS` - Extend `RUSTFLAGS` given to `cargo build` while building the wasm binary.
-- `WASM_BUILD_NO_COLOR` - Disable color output of the wasm build.
-- `WASM_TARGET_DIRECTORY` - Will copy any build Wasm binary to the given directory. The path needs to be absolute.
-- `WASM_BUILD_TOOLCHAIN` - The toolchain that should be used to build the Wasm binaries. The format needs to be the same
-                           as used by cargo, e.g. `nightly-2020-02-20`.
-- `CARGO_NET_OFFLINE` - If `true`, `--offline` will be passed to all processes launched to prevent network access.
-  Useful in offline environments.
-
-Each project can be skipped individually by using the environment variable `SKIP_PROJECT_NAME_WASM_BUILD`. Where
-`PROJECT_NAME` needs to be replaced by the name of the cargo project, e.g. `node-runtime` will be `NODE_RUNTIME`.
-
-## Prerequisites
-
-Wasm builder requires the following prerequisites for building the Wasm binary:
-
-- rust nightly + `wasm32-unknown-unknown` toolchain
-
-or
-
-- rust stable and version at least 1.68.0 + `wasm32-unknown-unknown` toolchain
-
-If a specific rust is installed with `rustup`, it is important that the wasm target is installed as well. For example if
-installing the rust from 20.02.2020 using `rustup install nightly-2020-02-20`, the wasm target needs to be installed as
-well `rustup target add wasm32-unknown-unknown --toolchain nightly-2020-02-20`.
