Partially Addresses #2500 Adds a `deprecate_controller_batch` call to the staking pallet that is callable by `Root` and `StakingAdmin`. To be used for controller account deprecation and removed thereafter. Adds `MaxControllersDeprecationBatch` pallet constant that defines max possible deprecations per call. - [x] Add `deprecate_controller_batch` call, and `MaxControllersInDeprecationBatch` constant. - [x] Add tests, benchmark, weights. Tests that weight is only consumed if unique pair. - [x] Adds `StakingAdmin` origin to staking's `AdminOrigin` type in westend runtime. - [x] Determined that worst case 5,900 deprecations does fit into `maxBlock` `proofSize` and `refTime` in both normal and operational thresholds, meaning we can deprecate all controllers for each network in one call. ## Block Weights By querying `consts.system.blockWeights` we can see that the `deprecate_controller_batch` weights fit within the `normal` threshold on Polkadot. #### `controller_deprecation_batch` where i = 5900: #### Ref time: 69,933,325,300 #### Proof size: 21,040,390 ### Polkadot ``` // consts.query.blockWeights maxBlock: { refTime: 2,000,000,000,000 proofSize: 18,446,744,073,709,551,615 } normal: { maxExtrinsic: { refTime: 1,479,873,955,000 proofSize: 13,650,590,614,545,068,195 } maxTotal: { refTime: 1,500,000,000,000 proofSize: 13,835,058,055,282,163,711 } } ``` ### Kusama ``` // consts.query.blockWeights maxBlock: { refTime: 2,000,000,000,000 proofSize: 18,446,744,073,709,551,615 } normal: { maxExtrinsic: { refTime: 1,479,875,294,000 proofSize: 13,650,590,614,545,068,195 } maxTotal: { refTime: 1,500,000,000,000 proofSize: 13,835,058,055,282,163,711 } } ``` --------- Co-authored-by: command-bot <> Co-authored-by: Gonçalo Pestana <g6pestana@gmail.com>
GRANDPA Consensus module for runtime.
This manages the GRANDPA authority set ready for the native code. These authorities are only for GRANDPA finality, not for consensus overall.
In the future, it will also handle misbehavior reports, and on-chain finality notifications.
For full integration with GRANDPA, the GrandpaApi should be implemented.
The necessary items are re-exported via the fg_primitives crate.
