## Problem During the bumping of the `polkadot-fellows` repository to `[email protected]`, I encountered a situation where the benchmarks `teleport_assets` and `reserve_transfer_assets` in AssetHubKusama started to fail. This issue arose due to a decreased ED balance for AssetHubs introduced [here](https://github.com/polkadot-fellows/runtimes/pull/158/files#diff-80668ff8e793b64f36a9a3ec512df5cbca4ad448c157a5d81abda1b15f35f1daR213), and also because of a [missing CI pipeline](https://github.com/polkadot-fellows/runtimes/issues/197) to check the benchmarks, which went unnoticed. These benchmarks expect the `caller` to have enough: 1. balance to transfer (BTT) 2. balance for paying delivery (BFPD). So the initial balance was calculated as `ED * 100`, which seems reasonable: ``` const ED_MULTIPLIER: u32 = 100; let balance = existential_deposit.saturating_mul(ED_MULTIPLIER.into());` ``` The problem arises when the price for delivery is 100 times higher than the existential deposit. In other words, when `ED * 100` does not cover `BTT` + `BFPD`. I check AHR/AHW/AHK/AHP and this problem has only AssetHubKusama ``` ED: 3333333 calculated price to parent delivery: 1031666634 (from xcm logs from the benchmark) --- 3333333 * 100 - BTT(3333333) - BFPD(1031666634) = −701666667 ``` which results in the error; ``` 2024-02-23 09:19:42 Unable to charge fee with error Module(ModuleError { index: 31, error: [17, 0, 0, 0], message: Some("FeesNotMet") }) Error: Input("Benchmark pallet_xcm::reserve_transfer_assets failed: FeesNotMet") ``` ## Solution The benchmarks `teleport_assets` and `reserve_transfer_assets` were fixed by removing `ED * 100` and replacing it with `DeliveryHelper` logic, which calculates the (almost real) price for delivery and sets it along with the existential deposit as the initial balance for the account used in the benchmark. ## TODO - [ ] patch for 1.6 - https://github.com/paritytech/polkadot-sdk/pull/3466 - [ ] patch for 1.7 - https://github.com/paritytech/polkadot-sdk/pull/3465 - [ ] patch for 1.8 - TODO: PR --------- Co-authored-by: Francisco Aguirre <[email protected]>

[frame] `#[pallet::composite_enum]` improved variant count handling + removed `pallet_balances`'s `MaxHolds` config (#2657) I started this investigation/issue based on @liamaharon question [here](https://github.com/paritytech/polkadot-sdk/pull/1801#discussion_r1410452499). ## Problem The `pallet_balances` integrity test should correctly detect that the runtime has correct distinct `HoldReasons` variant count. I assume the same situation exists for RuntimeFreezeReason. It is not a critical problem, if we set `MaxHolds` with a sufficiently large value, everything should be ok. However, in this case, the integrity_test check becomes less useful. **Situation for "any" runtime:** - `HoldReason` enums from different pallets: ```rust /// from pallet_nis #[pallet::composite_enum] pub enum HoldReason { NftReceipt, } /// from pallet_preimage #[pallet::composite_enum] pub enum HoldReason { Preimage, } // from pallet_state-trie-migration #[pallet::composite_enum] pub enum HoldReason { SlashForContinueMigrate, SlashForMigrateCustomTop, SlashForMigrateCustomChild, } ``` - generated `RuntimeHoldReason` enum looks like: ```rust pub enum RuntimeHoldReason { #[codec(index = 32u8)] Preimage(pallet_preimage::HoldReason), #[codec(index = 38u8)] Nis(pallet_nis::HoldReason), #[codec(index = 42u8)] StateTrieMigration(pallet_state_trie_migration::HoldReason), } ``` - composite enum `RuntimeHoldReason` variant count is detected as `3` - we set `type MaxHolds = ConstU32<3>` - `pallet_balances::integrity_test` is ok with `3`(at least 3) However, the real problem can occur in a live runtime where some functionality might stop working. This is due to a total of 5 distinct hold reasons (for pallets with multi-instance support, it is even more), and not all of them can be used because of an incorrect `MaxHolds`, which is deemed acceptable according to the `integrity_test`: ``` // pseudo-code - if we try to call all of these: T::Currency::hold(&pallet_nis::HoldReason::NftReceipt.into(), &nft_owner, deposit)?; T::Currency::hold(&pallet_preimage::HoldReason::Preimage.into(), &nft_owner, deposit)?; T::Currency::hold(&pallet_state_trie_migration::HoldReason::SlashForContinueMigrate.into(), &nft_owner, deposit)?; // With `type MaxHolds = ConstU32<3>` these two will fail T::Currency::hold(&pallet_state_trie_migration::HoldReason::SlashForMigrateCustomTop.into(), &nft_owner, deposit)?; T::Currency::hold(&pallet_state_trie_migration::HoldReason::SlashForMigrateCustomChild.into(), &nft_owner, deposit)?; ``` ## Solutions A macro `#[pallet::*]` expansion is extended of `VariantCount` implementation for the `#[pallet::composite_enum]` enum type. This expansion generates the `VariantCount` implementation for pallets' `HoldReason`, `FreezeReason`, `LockId`, and `SlashReason`. Enum variants must be plain enum values without fields to ensure a deterministic count. The composite runtime enum, `RuntimeHoldReason` and `RuntimeFreezeReason`, now sets `VariantCount::VARIANT_COUNT` as the sum of pallets' enum `VariantCount::VARIANT_COUNT`: ```rust #[frame_support::pallet(dev_mode)] mod module_single_instance { #[pallet::composite_enum] pub enum HoldReason { ModuleSingleInstanceReason1, ModuleSingleInstanceReason2, } ... } #[frame_support::pallet(dev_mode)] mod module_multi_instance { #[pallet::composite_enum] pub enum HoldReason<I: 'static = ()> { ModuleMultiInstanceReason1, ModuleMultiInstanceReason2, ModuleMultiInstanceReason3, } ... } impl self::sp_api_hidden_includes_construct_runtime::hidden_include::traits::VariantCount for RuntimeHoldReason { const VARIANT_COUNT: u32 = 0 + module_single_instance::HoldReason::VARIANT_COUNT + module_multi_instance::HoldReason::<module_multi_instance::Instance1>::VARIANT_COUNT + module_multi_instance::HoldReason::<module_multi_instance::Instance2>::VARIANT_COUNT + module_multi_instance::HoldReason::<module_multi_instance::Instance3>::VARIANT_COUNT; } ``` In addition, `MaxHolds` is removed (as suggested [here](https://github.com/paritytech/polkadot-sdk/pull/2657#discussion_r1443324573)) from `pallet_balances`, and its `Holds` are now bounded to `RuntimeHoldReason::VARIANT_COUNT`. Therefore, there is no need to let the runtime specify `MaxHolds`. ## For reviewers Relevant changes can be found here: - `substrate/frame/support/procedural/src/lib.rs` - `substrate/frame/support/procedural/src/pallet/parse/composite.rs` - `substrate/frame/support/procedural/src/pallet/expand/composite.rs` - `substrate/frame/support/procedural/src/construct_runtime/expand/composite_helper.rs` - `substrate/frame/support/procedural/src/construct_runtime/expand/hold_reason.rs` - `substrate/frame/support/procedural/src/construct_runtime/expand/freeze_reason.rs` - `substrate/frame/support/src/traits/misc.rs` And the rest of the files is just about removed `MaxHolds` from `pallet_balances` ## Next steps Do the same for `MaxFreezes` https://github.com/paritytech/polkadot-sdk/issues/2997. --------- Co-authored-by: command-bot <> Co-authored-by: Bastian Köcher <[email protected]> Co-authored-by: Dónal Murray <[email protected]> Co-authored-by: gupnik <[email protected]>

Reverts paritytech/polkadot-sdk#2302.
🤦 ♂️ should have checked the migration CI first. We either need to reduce the `max_message_size` for the open HRMP channels on the failing chains or increase the `PageSize` of the XCMP queue. Both would be fine on a test-net, but i assume this will also fail before the next SP runtime upgrade so first need to think what best to do. AFAIK its not possible currently to change the `max_message_size` of an open HRMP channel.

Remove `without_storage_info` from the XCMP queue pallet. Part of https://github.com/paritytech/polkadot-sdk/issues/323 Changes: - Limit the number of channels that can be suspended at the same time. - Limit the number of channels that can have messages or signals pending at the same time. A No-OP migration is put in place to ensure that all `BoundedVec`s still decode and not truncate after upgrade. The storage version is thereby bumped to 4 to have our tooling remind us to deploy that migration. --------- Signed-off-by: Oliver Tale-Yazdi <[email protected]> Co-authored-by: Francisco Aguirre <[email protected]>

# Note for reviewer Most changes are just syntax changes necessary for the new version. Most important files should be the ones under the `xcm` folder. # Description Added XCMv4. ## Removed `Multi` prefix The following types have been renamed: - MultiLocation -> Location - MultiAsset -> Asset - MultiAssets -> Assets - InteriorMultiLocation -> InteriorLocation - MultiAssetFilter -> AssetFilter - VersionedMultiAsset -> VersionedAsset - WildMultiAsset -> WildAsset - VersionedMultiLocation -> VersionedLocation In order to fix a name conflict, the `Assets` in `xcm-executor` were renamed to `HoldingAssets`, as they represent assets in holding. ## Removed `Abstract` asset id It was not being used anywhere and this simplifies the code. Now assets are just constructed as follows: ```rust let asset: Asset = (AssetId(Location::new(1, Here)), 100u128).into(); ``` No need for specifying `Concrete` anymore. ## Outcome is now a named fields struct Instead of ```rust pub enum Outcome { Complete(Weight), Incomplete(Weight, Error), Error(Error), } ``` we now have ```rust pub enum Outcome { Complete { used: Weight }, Incomplete { used: Weight, error: Error }, Error { error: Error }, } ``` ## Added Reanchorable trait Now both locations and assets implement this trait, making it easier to reanchor both. ## New syntax for building locations and junctions Now junctions are built using the following methods: ```rust let location = Location { parents: 1, interior: [Parachain(1000), PalletInstance(50), GeneralIndex(1984)].into() }; ``` or ```rust let location = Location::new(1, [Parachain(1000), PalletInstance(50), GeneralIndex(1984)]); ``` And they are matched like so: ```rust match location.unpack() { (1, [Parachain(id)]) => ... (0, Here) => ..., (1, [_]) => ..., } ``` This syntax is mandatory in v4, and has been also implemented for v2 and v3 for easier migration. This was needed to make all sizes smaller. # TODO - [x] Scaffold v4 - [x] Port github.com/paritytech/polkadot/pull/7236 - [x] Remove `Multi` prefix - [x] Remove `Abstract` asset id --------- Co-authored-by: command-bot <> Co-authored-by: Keith Yeung <[email protected]>

This PR creates all the missing `prdoc` files with some minimum content allowing to properly generate the changelog. The generated content is **not** suitable for the audience documentation. The audience documentation will be possible with the next version, when all PR come with a proper `prdoc`. ## Assumptions - the prdoc files for release `vX.Y.Z` have been moved under `prdoc/X.Y.Z` - the changelog requires for now for the prdoc files to contain author + topic.

Treasury Pallet Instance for the Fellowship in Westend Collectives. In this update, we present a Treasury Pallet Instance that is under the control of the Fellowship body, with oversight from the Root and Treasurer origins. Here's how it is governed: - the Root origin have the authority to reject or approve spend proposals, with no amount limit for approvals. - the Treasurer origin have the authority to reject or approve spend proposals, with approval limits of up to 10,000,000 DOT. - Voice of all Fellows ranked at 3 or above can reject or approve spend proposals, with a maximum approval limit of 10,000 DOT. - Voice of Fellows ranked at 4 or above can also reject or approve spend proposals, with a maximum approval limit of 10,000,000 DOT. Additionally, we introduce the Asset Rate Pallet Instance to establish conversion rates from asset A to B. This is used to determine if a proposed spend amount involving a non-native asset is permissible by the commanding origin. The rates can be set up by the Root, Treasurer origins, or Voice of all Fellows. --------- Co-authored-by: joe petrowski <[email protected]> Co-authored-by: joepetrowski <[email protected]>

# Motivation (+testing) ### Enable easy `ForeignAssets` transfers using `pallet-xcm` We had just previously added capabilities to teleport fees during reserve-based transfers, but what about reserve-transferring fees when needing to teleport some non-fee asset? This PR aligns everything under either explicit reserve-transfer, explicit teleport, or this new flexible `transfer_assets()` which can mix and match as needed with fewer artificial constraints imposed to the user. This will enable, for example, a (non-system) parachain to teleport their `ForeignAssets` assets to AssetHub while using DOT to pay fees. (the assets are teleported - as foreign assets should from their owner chain - while DOT used for fees can only be reserve-based transferred between said parachain and AssetHub). Added `xcm-emulator` tests for this scenario ^. # Description Reverts `(limited_)reserve_transfer_assets` to only allow reserve-based transfers for all `assets` including fees. Similarly `(limited_)teleport_assets` only allows teleports for all `assets` including fees. For complex combinations of asset transfers where assets and fees may have different reserves or different reserve/teleport trust configurations, users can use the newly added `transfer_assets()` extrinsic which is more flexible in allowing more complex scenarios. `assets` (excluding `fees`) must have same reserve location or otherwise be teleportable to `dest`. No limitations imposed on `fees`. - for local reserve: transfer assets to sovereign account of destination chain and forward a notification XCM to `dest` to mint and deposit reserve-based assets to `beneficiary`. - for destination reserve: burn local assets and forward a notification to `dest` chain to withdraw the reserve assets from this chain's sovereign account and deposit them to `beneficiary`. - for remote reserve: burn local assets, forward XCM to reserve chain to move reserves from this chain's SA to `dest` chain's SA, and forward another XCM to `dest` to mint and deposit reserve-based assets to `beneficiary`. - for teleports: burn local assets and forward XCM to `dest` chain to mint/teleport assets and deposit them to `beneficiary`. ## Review notes Only around 500 lines are prod code (see `pallet_xcm/src/lib.rs`), the rest of the PR is new tests and improving existing tests. --------- Co-authored-by: command-bot <>

## Overview This PR aligns the `spec_version` formatting to the [recent changes](https://github.com/polkadot-fellows/runtimes/pull/26/files#diff-efa4caeb17487ecb13d8f5eb7863c3241d84afa2e73fbf25909a2ca89df0f362R142) made for the Polkadot/Kusama runtimes. It also backports the latest version `v1.4.0` bumps as `1_004_000`. ## Details During the switch from `v0.9` to `v1.x`, the format of the `spec_version` was modified from: `(M)m_ppp` for a runtime considered on version `M.m.pp`. For instance `0.9.42` had a `spec_version` of `9420`. With the transition to `v1.x`, the format was changed to a bigger number (still `u32`) formatted as `MM_mm_ppp` where `1.2.3` would be stored as `01_02_003`. This PR aligns the format with that has been introduced in the fellowship repo: `MMM_mmm_ppp`. --------- Co-authored-by: Bastian Köcher <[email protected]>

## Motivation `pallet-xcm` is the main user-facing interface for XCM functionality, including assets manipulation functions like `teleportAssets()` and `reserve_transfer_assets()` calls. While `teleportAsset()` works both ways, `reserve_transfer_assets()` works only for sending reserve-based assets to a remote destination and beneficiary when the reserve is the _local chain_. ## Solution This PR enhances `pallet_xcm::(limited_)reserve_withdraw_assets` to support transfers when reserves are other chains. This will allow complete, **bi-directional** reserve-based asset transfers user stories using `pallet-xcm`. Enables following scenarios: - transferring assets with local reserve (was previously supported iff asset used as fee also had local reserve - now it works in all cases), - transferring assets with reserve on destination, - transferring assets with reserve on remote/third-party chain (iff assets and fees have same remote reserve), - transferring assets with reserve different than the reserve of the asset to be used as fees - meaning can be used to transfer random asset with local/dest reserve while using DOT for fees on all involved chains, even if DOT local/dest reserve doesn't match asset reserve, - transferring assets with any type of local/dest reserve while using fees which can be teleported between involved chains. All of the above is done by pallet inner logic without the user having to specify which scenario/reserves/teleports/etc. The correct scenario and corresponding XCM programs are identified, and respectively, built automatically based on runtime configuration of trusted teleporters and trusted reserves. #### Current limitations: - while `fees` and "non-fee" `assets` CAN have different reserves (or fees CAN be teleported), the remaining "non-fee" `assets` CANNOT, among themselves, have different reserve locations (this is also implicitly enforced by `MAX_ASSETS_FOR_TRANSFER=2`, but this can be safely increased in the future). - `fees` and "non-fee" `assets` CANNOT have **different remote** reserves (this could also be supported in the future, but adds even more complexity while possibly not being worth it - we'll see what the future holds).

(imported from https://github.com/paritytech/cumulus/pull/2157) ## Changes This MR refactores the XCMP, Parachains System and DMP pallets to use the [MessageQueue](https://github.com/paritytech/substrate/pull/12485) for delayed execution of incoming messages. The DMP pallet is entirely replaced by the MQ and thereby removed. This allows for PoV-bounded execution and resolves a number of issues that stem from the current work-around. All System Parachains adopt this change. The most important changes are in `primitives/core/src/lib.rs`, `parachains/common/src/process_xcm_message.rs`, `pallets/parachain-system/src/lib.rs`, `pallets/xcmp-queue/src/lib.rs` and the runtime configs. ### DMP Queue Pallet The pallet got removed and its logic refactored into parachain-system. Overweight message management can be done directly through the MQ pallet. Final undeployment migrations are provided by `cumulus_pallet_dmp_queue::UndeployDmpQueue` and `DeleteDmpQueue` that can be configured with an aux config trait like: ```rust parameter_types! { pub const DmpQueuePalletName: &'static str = \"DmpQueue\" < CHANGE ME; pub const RelayOrigin: AggregateMessageOrigin = AggregateMessageOrigin::Parent; } impl cumulus_pallet_dmp_queue::MigrationConfig for Runtime { type PalletName = DmpQueuePalletName; type DmpHandler = frame_support::traits::EnqueueWithOrigin<MessageQueue, RelayOrigin>; type DbWeight = <Runtime as frame_system::Config>::DbWeight; } // And adding them to your Migrations tuple: pub type Migrations = ( ... cumulus_pallet_dmp_queue::UndeployDmpQueue<Runtime>, cumulus_pallet_dmp_queue::DeleteDmpQueue<Runtime>, ); ``` ### XCMP Queue pallet Removed all dispatch queue functionality. Incoming XCMP messages are now either: Immediately handled if they are Signals, enqueued into the MQ pallet otherwise. New config items for the XCMP queue pallet: ```rust /// The actual queue implementation that retains the messages for later processing. type XcmpQueue: EnqueueMessage<ParaId>; /// How a XCM over HRMP from a sibling parachain should be processed. type XcmpProcessor: ProcessMessage<Origin = ParaId>; /// The maximal number of suspended XCMP channels at the same time. #[pallet::constant] type MaxInboundSuspended: Get<u32>; ``` How to configure those: ```rust // Use the MessageQueue pallet to store messages for later processing. The `TransformOrigin` is needed since // the MQ pallet itself operators on `AggregateMessageOrigin` but we want to enqueue `ParaId`s. type XcmpQueue = TransformOrigin<MessageQueue, AggregateMessageOrigin, ParaId, ParaIdToSibling>; // Process XCMP messages from siblings. This is type-safe to only accept `ParaId`s. They will be dispatched // with origin `Junction::Sibling(…)`. type XcmpProcessor = ProcessFromSibling< ProcessXcmMessage< AggregateMessageOrigin, xcm_executor::XcmExecutor<xcm_config::XcmConfig>, RuntimeCall, >, >; // Not really important what to choose here. Just something larger than the maximal number of channels. type MaxInboundSuspended = sp_core::ConstU32<1_000>; ``` The `InboundXcmpStatus` storage item was replaced by `InboundXcmpSuspended` since it now only tracks inbound queue suspension and no message indices anymore. Now only sends the most recent channel `Signals`, as all prio ones are out-dated anyway. ### Parachain System pallet For `DMP` messages instead of forwarding them to the `DMP` pallet, it now pushes them to the configured `DmpQueue`. The message processing which was triggered in `set_validation_data` is now being done by the MQ pallet `on_initialize`. XCMP messages are still handed off to the `XcmpMessageHandler` (XCMP-Queue pallet) - no change here. New config items for the parachain system pallet: ```rust /// Queues inbound downward messages for delayed processing. /// /// Analogous to the `XcmpQueue` of the XCMP queue pallet. type DmpQueue: EnqueueMessage<AggregateMessageOrigin>; ``` How to configure: ```rust /// Use the MQ pallet to store DMP messages for delayed processing. type DmpQueue = MessageQueue; ``` ## Message Flow The flow of messages on the parachain side. Messages come in from the left via the `Validation Data` and finally end up at the `Xcm Executor` on the right. ![Untitled (1)](https://github.com/paritytech/cumulus/assets/10380170/6cf8b377-88c9-4aed-96df-baace266e04d) ## Further changes - Bumped the default suspension, drop and resume thresholds in `QueueConfigData::default()`. - `XcmpQueue::{suspend_xcm_execution, resume_xcm_execution}` errors when they would be a noop. - Properly validate the `QueueConfigData` before setting it. - Marked weight files as auto-generated so they wont auto-expand in the MR files view. - Move the `hypothetical` asserts to `frame_support` under the name `experimental_hypothetically` Questions: - [ ] What about the ugly `#[cfg(feature = \"runtime-benchmarks\")]` in the runtimes? Not sure how to best fix. Just having them like this makes tests fail that rely on the real message processor when the feature is enabled. - [ ] Need a good weight for `MessageQueueServiceWeight`. The scheduler already takes 80% so I put it to 10% but that is quite low. TODO: - [x] Remove c&p code after https://github.com/paritytech/polkadot/pull/6271 - [x] Use `HandleMessage` once it is public in Substrate - [x] fix `runtime-benchmarks` feature https://github.com/paritytech/polkadot/pull/6966 - [x] Benchmarks - [x] Tests - [ ] Migrate `InboundXcmpStatus` to `InboundXcmpSuspended` - [x] Possibly cleanup Migrations (DMP+XCMP) - [x] optional: create `TransformProcessMessageOrigin` in Substrate and replace `ProcessFromSibling` - [ ] Rerun weights on ref HW --------- Signed-off-by: Oliver Tale-Yazdi <[email protected]> Co-authored-by: Liam Aharon <[email protected]> Co-authored-by: joe petrowski <[email protected]> Co-authored-by: Kian Paimani <[email protected]> Co-authored-by: command-bot <>

closes https://github.com/paritytech/polkadot-sdk/issues/1882 ## Breaking Changes This PR introduces a new item to `pallet_balances::Config`: ```diff trait Config { ++ type RuntimeFreezeReasons; } ``` This value is only used to check it against `type MaxFreeze`. A similar check has been added for `MaxHolds` against `RuntimeHoldReasons`, which is already given to `pallet_balances`. In all contexts, you should pass the real `RuntimeFreezeReasons` generated by `construct_runtime` to `type RuntimeFreezeReasons`. Passing `()` would also work, but it would imply that the runtime uses no freezes at all. --------- Signed-off-by: Oliver Tale-Yazdi <[email protected]> Co-authored-by: Oliver Tale-Yazdi <[email protected]>

Combination of paritytech/polkadot#7005, its addon PR paritytech/polkadot#7585 and its companion paritytech/cumulus#2433. This PR introduces a new XcmFeesToAccount struct which implements the `FeeManager` trait, and assigns this struct as the `FeeManager` in the XCM config for all runtimes. The struct simply deposits all fees handled by the XCM executor to a specified account. In all runtimes, the specified account is configured as the treasury account. XCM __delivery__ fees are now being introduced (unless the root origin is sending a message to a system parachain on behalf of the originating chain). # Note for reviewers Most file changes are tests that had to be modified to account for the new fees. Main changes are in: - cumulus/pallets/xcmp-queue/src/lib.rs <- To make it track the delivery fees exponential factor - polkadot/xcm/xcm-builder/src/fee_handling.rs <- Added. Has the FeeManager implementation - All runtime xcm_config files <- To add the FeeManager to the XCM configuration # Important note After this change, instructions that create and send a new XCM (Query*, Report*, ExportMessage, InitiateReserveWithdraw, InitiateTeleport, DepositReserveAsset, TransferReserveAsset, LockAsset and RequestUnlock) will require the corresponding origin account in the origin register to pay for transport delivery fees, and the onward message will fail to be sent if the origin account does not have the required amount. This delivery fee is on top of what we already collect as tx fees in pallet-xcm and XCM BuyExecution fees! Wallet UIs that want to expose the new delivery fee can do so using the formula: ``` delivery_fee_factor * (base_fee + encoded_msg_len * per_byte_fee) ``` where the delivery fee factor can be obtained from the corresponding pallet based on which transport you are using (UMP, HRMP or bridges), the base fee is a constant, the encoded message length from the message itself and the per byte fee is the same as the configured per byte fee for txs (i.e. `TransactionByteFee`). --------- Co-authored-by: Branislav Kontur <[email protected]> Co-authored-by: joe petrowski <[email protected]> Co-authored-by: Giles Cope <[email protected]> Co-authored-by: command-bot <> Co-authored-by: Francisco Aguirre <[email protected]> Co-authored-by: Liam Aharon <[email protected]> Co-authored-by: Kian Paimani <[email protected]>

The Ambassador Program on Polkadot Collectives Parachain The Polkadot Ambassador Program has existed for a while; more information can be found [here](https://wiki.polkadot.network/docs/ambassadors). In this PR, the program is being brought on chain. ### On Chain Structure The on-chain program consists of nine ranks, divided into four categories ([full list](https://github.com/paritytech/cumulus/blob/c238fb26b75569a11abb57437fd14acd26e05f18/parachains/runtimes/collectives/collectives-polkadot/src/ambassador/mod.rs#L52)): - Ambassadors (1-2 tiers) - Senior Ambassadors (3-4 tiers) - Head Ambassadors (5-7 tiers) - Master Ambassadors (8-9 tiers) Each rank has a corresponding `Origin` (e.g., `HeadAmbassadorsTier5` - [full list](https://github.com/paritytech/cumulus/blob/c238fb26b75569a11abb57437fd14acd26e05f18/parachains/runtimes/collectives/collectives-polkadot/src/ambassador/origins.rs#L35)), which represents the collective voice of members of that rank and above. ### Referendum The `AmbassadorReferenda` instance of [referenda pallet](https://docs.rs/pallet-referenda/latest/pallet_referenda/) consists of [nine tracks](https://github.com/paritytech/cumulus/blob/c238fb26b75569a11abb57437fd14acd26e05f18/parachains/runtimes/collectives/collectives-polkadot/src/ambassador/tracks.rs#L51), each corresponding to an `Origin`. A referendum taken on `senior ambassador tier 4` track invites all members from rank 4 or above to vote and commands `SeniorAmbassadors` `Origin`. Every member gets one vote plus an additional vote for every excess rank. The referendum proposal can be submitted by any member of a senior rank or above. ### Membership Management Initial members will be brought on chain via migration, with subsequent member management handled through the `AmbassadorCollective` instance of [ranked collective pallet](https://docs.rs/pallet-ranked-collective/latest/pallet_ranked_collective/). Both `Root` and `FellowshipAdmin` `Origins`, commanded via public Polkadot referendum, can promote or demote members to and from any rank. Members themselves also have the power to promote or demote via its referendum, with a senior member vote by the rank two above the new / current rank - [full configuration](https://github.com/paritytech/cumulus/blob/9ab6aa47063d7e8b67ddc10d9c136037f99c03a3/parachains/runtimes/collectives/collectives-polkadot/src/ambassador/mod.rs#L67). ### Content Management The program's on-chain content is managed via the collectives content pallet, allowing for setting its charter and making announcements. The voice of head ambassadors have the authority to set the charter, while announcements can be made by any senior rank member or through a referendum among all members. ### Additional Functionality The `AmbassadorCore` instance of [core fellowship pallet](https://docs.rs/pallet-core-fellowship/latest/pallet_core_fellowship/) decorates the ranked collectives pallet with features like salary determination, activity/passivity registration, and the handling of promotion and demotion periods. While the usage of this pallet is optional in the first version, future updates will make it the exclusive method for induction/promotion. Periodic salaries in USDt, payable on Asset Hub, are introduced through the [salary pallet](https://docs.rs/pallet-salary/latest/pallet_salary/). This requires induction into the ambassador core pallet. Please for more information on the pallets' functionality refer to their documentations. ### Next Steps: - Migrate to seed the program members - Mint ambassador NFT badges on Asset Hub when promoting - Treasury pallet instance for the Ambassador Program --------- Co-authored-by: Kian Paimani <[email protected]> Co-authored-by: joe petrowski <[email protected]>

## Summary The term "common good parachain" has been abandoned in favor of "system parachain" - e.g. [Joe's speech at Decoded2023](https://youtu.be/CSO-ERHK2gY?t=456). This pull request tries to fix and align code with this vision. ## Impact The important change is implementation of `trait IsSystem` for `Id` [here](https://github.com/paritytech/polkadot-sdk/pull/1406/files#diff-0b7b4f5b962a18ce980354592b55ab2a27b5a2e9f6f8089ec803ca73853e8583R225-R229) where we changed condition from `< 1000` to `<= 1999`, which means that all parachain IDs bellow 1999 (included) are considered as "system parachain" IDs. This change has a direct impact on the following components: #### [ChildSystemParachainAsSuperuser](https://github.com/paritytech/polkadot-sdk/blob/master/polkadot/xcm/xcm-builder/src/origin_conversion.rs#L72-L88) This origin converter is used for allowing to process XCM `Transact` from "system parachain" on the relay chain - e.g. see [configuration for Kusama](https://github.com/paritytech/polkadot-sdk/blob/master/polkadot/runtime/kusama/src/xcm_config.rs#L92-L101). Only configured for Kusama, Westend, Rococo runtimes. **No need for this feature anymore.** See [comment](https://github.com/paritytech/polkadot-sdk/pull/1406#issuecomment-1708218715). #### [IsChildSystemParachain](https://github.com/paritytech/polkadot-sdk/blob/master/polkadot/xcm/xcm-builder/src/barriers.rs#L310-L317) `IsChildSystemParachain` is used with `AllowExplicitUnpaidExecutionFrom` barrier for checking XCM programs (they have to start with `UnpaidExecution` instruction). Only configured for Kusama, Westend, Rococo runtimes. **Overall the impact is low or mostly ok because it only allows unpaid execution for "system parachains" (e.g. AssetHub, BridgeHub...) on the relay chain.** #### [SiblingSystemParachainAsSuperuser](https://github.com/paritytech/polkadot-sdk/blob/master/polkadot/xcm/xcm-builder/src/origin_conversion.rs#L94-L114) Not used anywhere in `polkadot-sdk` repo. ## Unresolved Questions - [ ] constants `LOWEST_USER_ID` and `LOWEST_PUBLIC_ID` seem to express the same thing now, do we want to keep them both or deprecated one of them? If so, which one? - [x] determine impact for `ChildSystemParachainAsSuperuser` ## TODO - [ ] when merged here, open PR to the `polkadot-fellows` ## Related Material https://youtu.be/CSO-ERHK2gY?t=456 https://forum.polkadot.network/t/polkadot-protocol-and-common-good-parachains/866 https://wiki.polkadot.network/docs/learn-system-chains
