      Use `Message Queue` as DMP and XCMP dispatch queue (#1246) · e1c033eb
      Oliver Tale-Yazdi authored
      
      
      (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.

      (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

      replace `ProcessFromSibling`

      [testnet] Add `AssetHubRococo` <-> `AssetHubWestend` asset bridging support (#1967) · 1b1fab0d
      Branislav Kontur authored
      
      
      ## Summary
      
      Asset bridging support for AssetHub**Rococo** <-> AssetHub**Wococo** was
      added [here](https://github.com/paritytech/polkadot-sdk/pull/1215), so
      now we aim to bridge AssetHub**Rococo** and AssetHub**Westend**. (And
      perhaps retire AssetHubWococo and the Wococo chains).
      
      ## Solution
      
      **bridge-hub-westend-runtime**
      - added new runtime as a copy of `bridge-hub-rococo-runtime`
      - added support for bridging to `BridgeHubRococo`
      - added tests and benchmarks
      
      **bridge-hub-rococo-runtime**
      - added support for bridging to `BridgeHubWestend`
      - added tests and benchmarks
      - internal refactoring by splitting bridge configuration per network,
      e.g., `bridge_to_whatevernetwork_config.rs`.
      
      **asset-hub-rococo-runtime**
      - added support for asset bridging to `AssetHubWestend` (allows to
      receive only WNDs)
      - added new xcm router for `Westend`
      - added tests and benchmarks
      
      **asset-hub-westend-runtime**
      - added support for asset bridging to `AssetHubRococo` (allows to
      receive only ROCs)
      - added new xcm router for `Rococo`
      - added tests and benchmarks
      
      ## Deployment
      
      All changes will be deployed as a part of
      https://github.com/paritytech/polkadot-sdk/issues/1988.
      
      ## TODO
      
      - [x] benchmarks for all pallet instances
      - [x] integration tests
      - [x] local run scripts

      Automatically build and attach production and dev runtimes to GH releases (#2054) · a7061712
      Liam Aharon authored
      
      
      Closes https://github.com/paritytech/release-engineering/issues/6
      
      Adds a new Github Workflow which on a new release being created, builds
      and attaches all runtimes managed in this repository in two flavours:
      - `dev-debug-build`: Built with the `try-runtime` feature and has
      logging enabled
      - `on-chain-release`: Built with the regular old `on-chain-release`
      feature
      
      The new Github Workflow could be extended in the future by the
      @paritytech/release-engineering team to fully automate the release
      process if they choose to, similar to how it is fully automated in the
      Fellowship repo
      (https://github.com/polkadot-fellows/runtimes/blob/main/.github/workflows/release.yml).
      
      The `on-chain-release` did not exist for parachains, so I added it.

      Expose collection attributes from `Inspect` trait (#1914) · 0bcebac4
      Dastan authored
      # Description
      
      - What does this PR do?
      
      While working with `pallet_nfts` through `nonfungibles_v2` traits
      `Inspect, Mutate`, I found out that once you have set the collection
      attribute with `<Nfts as Mutate>::set_collection_attribute()`, it's not
      possible to read it with `<Nfts as Inspect>::collection_attribute()`
      since they use different `namespace` values. When setting the attribute,
      `AttributeNamespace::Pallet` is used, while
      `AttributeNamespace::CollectionOwner` is used when reading.
      
      more context:
      https://github.com/freeverseio/laos/issues/7#issuecomment-1766137370
      
      This PR makes `item` an optional parameter in
      `Inspect::system_attribute()`, to be able to read collection attributes.
      
      - Why are these changes needed?
      
      To be able to read collection level attributes when reading attributes
      of the collection. It will be possible to read collection attributes by
      passing `None` for `item`
      
      - How were these changes implemented and what do they affect?
      
      `NftsApi` is also affected and `NftsApi::system_attribute()` now accepts
      optional `item` parameter.
      
      ## Breaking change
      
      Because of the change in the `NftsApi::system_attribute()` method's
      `item` param, parachains who integrated the `NftsApi` need to update
      their API code and frontend integrations accordingly. AssetHubs are
      unaffected since the NftsApi wasn't released on those parachains yet.

      Oliver Tale-Yazdi authored
      
      
      Adds a config file that allows to run `zepter` without any arguments in
      the workspace to address all issues.
      A secondary workflow for the CI is provided as `zepter run check`. Both
      the formatting and linting are now in one check for efficiancy.
      
      The latest version also detects some more things that `featalign` was
      already showing.
      
      Error message [in the
      CI](https://gitlab.parity.io/parity/mirrors/polkadot-sdk/-/jobs/3916205)
      now looks like this:

      Error: Command 'lint propagate-feature' failed with exit code 1
      
      Polkadot-SDK uses the Zepter CLI to detect abnormalities in the feature configuration.
      It looks like one more more checks failed; please check the console output. You can try to automatically address them by running `zepter`.
      Otherwise please ask directly in the Merge Request, GitHub Discussions or on Matrix Chat, thank you.

      ## 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.

      This PR does not introduce any functional changes to the existing code,
      it merely addresses several minor refactors:
      - Moving bridging pallets to separate files.
      - Improving the readability and naming of weight files for bridging
      pallets and bridging pallet instances.
      
      The reason for this refactor is to facilitate easier plugin integration
      for the upcoming bridge between Rococo and Westend.

      - Replaced `<rococo_runtime::Treasury as PalletInfoAccess>::index()`
      with `rococo_runtime_constants::TREASURY_PALLET_ID`.
      - Added `check_treasury_pallet_id` to the relay runtimes to ensure that
      the constant is aligned with the pallet id.
      - Added "Rococo Treasury" to the waived locations (that will not be
      charged fees in the executor) for `BridgeHubRococo` (to be aligned with
      AssetHubs).

      `xcm`: Change `TypeInfo::path` to not include `staging` (#1948) · f3bf5c1a
      Bastian Köcher authored
      
      
      The `xcm` crate was renamed to `staging-xcm` to be able to publish it to
      crates.io as someone as squatted `xcm`. The problem with this rename is
      that the `TypeInfo` includes the crate name which ultimately lands in
      the metadata. The metadata is consumed by downstream users like
      `polkadot-js` or people building on top of `polkadot-js`. These people
      are using the entire `path` to find the type in the type registry. Thus,
      their code would break as the type path would now be [`staging_xcm`,

      Introduce XcmFeesToAccount fee manager (#1234) · 3dece311
      Keith Yeung authored
      
      
      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`).

      [xcm] Small enhancements for `NetworkExportTable` and `xcm-builder` (#1848) · 5cdd819e
      Branislav Kontur authored
      
      
      ## Summary
      
      This PR introduces several enhancements.
      
      The current implementation of `NetworkExportTable` lacks remote location
      filtering support beyond `NetworkId` lookup. To provide more control and
      granularity, it's essential to allow configuration for bridging to
      different consensus `NetworkId` while restricting access e.g. to
      particular remote parachains.
      
      Additionally, the `StartsWith` and `Equals` and
      `StartsWithExplicitGlobalConsensus` helper functions, which are in
      active use, are moved to the `xcm-builder` and `frame_support` modules
      for better code organization.
      
      Adds a new `LocationWithAssetFilters` filter to enable location-based
      and asset-related filtering. This filter is useful for configuring the
      `pallet_xcm` filter for
      [XcmTeleportFilter](https://github.com/paritytech/polkadot-sdk/blob/master/polkadot/xcm/pallet-xcm/src/lib.rs#L212)
      and
      [XcmReserveTransferFilter](https://github.com/paritytech/polkadot-sdk/blob/master/polkadot/xcm/pallet-xcm/src/lib.rs#L216)
      to restrict specific assets.
      
      Furthermore, the `BridgeMessage` fields are not accessible outside of
      `xcm-builder`, limiting the ability to create custom logic dependent on
      it.

      Branislav Kontur authored
      [xcm] Use `Weight::MAX` for `reserve_asset_deposited`, `receive_teleported_asset` benchmarks (#1726)
      
      # Description
      
      ## Summary
      
      Previously, the `pallet_xcm::do_reserve_transfer_assets` and
      `pallet_xcm::do_teleport_assets` functions relied on weight estimation
      for remote chain execution, which was based on guesswork derived from
      the local chain. This approach led to complications for runtimes that
      did not provide or support specific [XCM
      configurations](https://github.com/paritytech/polkadot-sdk/blob/7cbe0c76/polkadot/xcm/xcm-executor/src/config.rs#L43-L47)
      for `IsReserve` or `IsTeleporter`. Consequently, such runtimes had to
      resort to implementing hard-coded weights for XCM instructions like
      `reserve_asset_deposited` or `receive_teleported_asset` to support
      extrinsics such as `pallet_xcm::reserve_transfer_assets` and
      `pallet_xcm::teleport_assets`, which depended on remote weight
      estimation.
      
      The issue of remote weight estimation was addressed and resolved by
      [Pull Request
      #1645](https://github.com/paritytech/polkadot-sdk/pull/1645), which
      removed the need for remote weight estimation.
      
      ## Solution
      
      As a continuation of this improvement, the current PR proposes further
      cleanup by removing unnecessary hard-coded values and rectifying
      benchmark results with `Weight::MAX` that previously used
      `T::BlockWeights::get().max_block` as an override for unsupported XCM
      instructions like `ReserveAssetDeposited` and `ReceiveTeleportedAsset`.
      
      
      ## Questions
      
      - [x] Can we remove now also `Hardcoded till the XCM pallet is fixed`
      for `deposit_asset`? E.g. for AssetHubKusama
      [here](https://github.com/paritytech/polkadot-sdk/blob/7cbe0c76/cumulus/parachains/runtimes/assets/asset-hub-kusama/src/weights/xcm/mod.rs#L129-L134)
      - [x] Are comments like
      [this](https://github.com/paritytech/polkadot-sdk/blob/7cbe0c76/polkadot/runtime/kusama/src/weights/xcm/mod.rs#L94)
      `// Kusama doesn't support ReserveAssetDeposited, so this benchmark has
      a default weight` still relevant? Shouldnt be removed/changed?
      
      
      ## TODO
      
      - [x] `bench bot` regenerate xcm weights for all runtimes
      - [x] remove hard-coded stuff from system parachain weight files
      - [ ] when merged, open `polkadot-fellow/runtimes` PR

      Treasury spends various asset kinds (#1333) · cb944dc5
      Muharem Ismailov authored
      
      
      ### Summary 
      
      This PR introduces new dispatchables to the treasury pallet, allowing
      spends of various asset types. The enhanced features of the treasury
      pallet, in conjunction with the asset-rate pallet, are set up and
      enabled for Westend and Rococo.
      
      ### Westend and Rococo runtimes.
      
      Polkadot/Kusams/Rococo Treasury can accept proposals for `spends` of
      various asset kinds by specifying the asset's location and ID.
      
      #### Treasury Instance New Dispatchables:
      - `spend(AssetKind, AssetBalance, Beneficiary, Option<ValidFrom>)` -
      propose and approve a spend;
      - `payout(SpendIndex)` - payout an approved spend or retry a failed
      payout
      - `check_payment(SpendIndex)` - check the status of a payout;
      - `void_spend(SpendIndex)` - void previously approved spend;
      > existing spend dispatchable renamed to spend_local
      
      in this context, the `AssetKind` parameter contains the asset's location
      and it's corresponding `asset_id`, for example:
      `USDT` on `AssetHub`,
      ``` rust
      location = MultiLocation(0, X1(Parachain(1000)))
      asset_id = MultiLocation(0, X2(PalletInstance(50), GeneralIndex(1984)))
      ```
      
      the `Beneficiary` parameter is a `MultiLocation` in the context of the
      asset's location, for example
      ``` rust
      // the Fellowship salary pallet's location / account
      FellowshipSalaryPallet = MultiLocation(1, X2(Parachain(1001), PalletInstance(64)))
      // or custom `AccountId`
      Alice = MultiLocation(0, AccountId32(network: None, id: [1,...]))
      ```
      
      the `AssetBalance` represents the amount of the `AssetKind` to be
      transferred to the `Beneficiary`. For permission checks, the asset
      amount is converted to the native amount and compared against the
      maximum spendable amount determined by the commanding spend origin.
      
      the `spend` dispatchable allows for batching spends with different
      `ValidFrom` arguments, enabling milestone-based spending. If the
      expectations tied to an approved spend are not met, it is possible to
      void the spend later using the `void_spend` dispatchable.
      
      Asset Rate Pallet provides the conversion rate from the `AssetKind` to
      the native balance.
      
      #### Asset Rate Instance Dispatchables:
      - `create(AssetKind, Rate)` - initialize a conversion rate to the native
      balance for the given asset
      - `update(AssetKind, Rate)` - update the conversion rate to the native
      balance for the given asset
      - `remove(AssetKind)` - remove an existing conversion rate to the native
      balance for the given asset
      
      the pallet's dispatchables can be executed by the Root or Treasurer
      origins.
      
      ### Treasury Pallet
      
      Treasury Pallet can accept proposals for `spends` of various asset kinds
      and pay them out through the implementation of the `Pay` trait.
      
      New Dispatchables:
      - `spend(Config::AssetKind, AssetBalance, Config::Beneficiary,
      Option<ValidFrom>)` - propose and approve a spend;
      - `payout(SpendIndex)` - payout an approved spend or retry a failed
      payout;
      - `check_payment(SpendIndex)` - check the status of a payout;
      - `void_spend(SpendIndex)` - void previously approved spend;
      > existing spend dispatchable renamed to spend_local
      
      The parameters' types of the `spend` dispatchable exposed via the
      pallet's `Config` and allows to propose and accept a spend of a certain
      amount.
      
      An approved spend can be claimed via the `payout` within the
      `Config::SpendPeriod`. Clients provide an implementation of the `Pay`
      trait which can pay an asset of the `AssetKind` to the `Beneficiary` in
      `AssetBalance` units.
      
      The implementation of the Pay trait might not have an immediate final
      payment status, for example if implemented over `XCM` and the actual
      transfer happens on a remote chain.
      
      The `check_status` dispatchable can be executed to update the spend's
      payment state and retry the `payout` if the payment has failed.

      Init System Parachain storage versions and add migration check jobs to CI (#1344) · db3fd687
      Liam Aharon authored
      Makes SPs first class citizens along with the relay chains in the
      context of our CI runtime upgrade checks.
      
      ## Code changes
      
      - Sets missing current storage version in `uniques` pallet
      - Adds multisig V1 migration to run where it was missing
      - Removes executed migration whos pre/post hooks were failing from
      collectives runtime
      - Initializes storage versions for SP pallets added after genesis
      - Originally I was going to wait for
      https://github.com/paritytech/polkadot-sdk/pull/1297 to be merged so
      this wouldn't need to be done manually, but it doesn't seem like it'll
      be merged any time soon so I've decided to set them manually to unblock
      this
      
      ## CI changes
      
      - Removed dependency of `westend` runtime upgrades being complete prior
      to other ones running. I assume it is supposed to cache the
      `try-runtime` build for a performance benefit, but it seems it wasn't
      working. Maybe someone from the CI team can look into this or explain
      why it needs to be there?
      
      - Adds check-runtime-migration jobs for Parity asset-hubs, bridge-hubs
      and contract chains
      
      - Updated VARIABLES to accomodate the `kusama-runtime` package being
      renamed to `staging-kusama-runtime` in
      https://github.com/paritytech/polkadot-sdk/pull/1241
      
      - Added `EXTRA_ARGS` variable to `check-runtime-migration`, and set
      `--no-weight-warnings` to the relay chain runtime upgrade checks (relay
      chains don't have weight restrictions).

      Remove kusama and polkadot runtime crates (#1731) · bf90cb0b
      Bastian Köcher authored
      This pull request is removing the Kusama and Polkadot runtime crates. As
      still some crates dependent on the runtime crates, this pull request is
      doing some more changes.
      
      - It removes the `hostperfcheck` CLI command. This CLI command could
      compare the current node against the standard hardware by doing some
      checks. Later we added the hardware benchmark feature to Substrate. This
      hardware benchmark is running on every node startup and prints a warning
      if the current node is too slow. This makes this CLI command a duplicate
      that was also depending on the kusama runtime.
      
      - The pull request is removing the emulated integration tests that were
      requiring the Kusama or Polkadot runtime crates.

      The Ambassador Program (#1308) · 9e403629
      Muharem Ismailov authored
      
      
      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
