import { PalletsStakingProgressService } from '../../services'; import AbstractController from '../AbstractController'; /** * GET progress on the general Staking pallet system. * * Query params: * - (Optional)`at`: Block at which to retrieve runtime version information at. Block * identifier, as the block height or block hash. Defaults to most recent block. * * Returns: * - `at`: Block number and hash at which the call was made. * - `activeEra`: `EraIndex` of the era being rewarded. * - `forceEra`: Current status of era forcing. * - `nextActiveEraEstimate`: **Upper bound estimate** of the block height at which the next * active era will start. Not included in response when `forceEra.isForceNone`. * - `nextSessionEstimate`: **Upper bound estimate** of the block height at which the next * session will start. * - `unappliedSlashes`: Array of upcoming `UnappliedSlash` indexed by era. Each `UnappliedSlash` * contains: * - `validator`: Stash account ID of the offending validator. * - `own`: The amount the validator will be slashed. * - `others`: Array of tuples of (accountId, amount) representing all the stashes of other * slashed stakers and the amount they will be slashed. * - `reporters`: Array of account IDs of the reporters of the offense. * - `payout`: Amount of bounty payout to reporters. * - `electionStatus`: Information about the off-chain election. Not included in response when * `forceEra.isForceNone`. Response includes: * - `status`: Era election status; either `Close: null` or `Open: <BlockNumber>`. A status of * `Close` indicates that the submission window for solutions from off-chain Phragmen is not * open. A status of `Open` indicates the submission window for off-chain Phragmen solutions * has been open since BlockNumber. N.B. when the submission window is open, certain * extrinsics are not allowed because they would mutate the state that the off-chain Phragmen * calculation relies on for calculating results. * - `toggleEstimate`: **Upper bound estimate** of the block height at which the `status` will * switch. * - `idealValidatorCount`: Upper bound of validator set size; considered the ideal size. Not * included in response when `forceEra.isForceNone`. * - `validatorSet`: Stash account IDs of the validators for the current session. Not included in * response when `forceEra.isForceNone`. * * Note about 'active' vs. 'current' era: The _active_ era is the era currently being rewarded. * That is, an elected validator set will be in place for an entire active era, as long as none * are kicked out due to slashing. Elections take place at the end of each _current_ era, which * is the latest planned era, and may not equal the active era. Normally, the current era index * increments one session before the active era, in order to perform the election and queue the * validator set for the next active era. For example: * * ``` * Time: ---------> * CurrentEra: 1 | 2 | * ActiveEra: | 1 | 2 | * SessionIdx: | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | * Elections: ^ ^ * Set Changes: ^ ^ * ``` * * Substrate Reference: * - Staking Pallet: https://crates.parity.io/pallet_staking/index.html * - Session Pallet: https://crates.parity.io/pallet_session/index.html * - `Forcing`: https://crates.parity.io/pallet_staking/enum.Forcing.html * - `ElectionStatus`: https://crates.parity.io/pallet_staking/enum.ElectionStatus.html */ export default class PalletsStakingProgressController extends AbstractController<PalletsStakingProgressService> { static controllerName: string; static requiredPallets: string[][]; constructor(api: string); protected initRoutes(): void; /** * Get the progress of the staking pallet system. * * @param _req Express Request * @param res Express Response */ private getPalletStakingProgress; }
