Staking Extend

Methods

current_staking_era

fn current_staking_era() -> u32

Get the Era of the current Staking pallet.

near_era_change

fn near_era_change(period_multiple: BlockNumber) -> bool

Used to determine whether era changes are about to occur.

period_multiple: session-multi indicates the trigger pre-check session period before the era.

calculate_near_era_change

fn calculate_near_era_change(
    period_multiple: BlockNumber,
    current_bn: BlockNumber,
    session_length: BlockNumber,
    per_era: BlockNumber
) -> bool

old_npos

fn old_npos() -> Vec<Self::StashId>

Get the list of validators before the election.

pending_npos

fn pending_npos() -> Vec<(Self::StashId, Option<AuthorityId>)>

Get the list of new validators after the current election, excluding validators from the previous session.

Workflow

Adapter execution

  1. ElectionProvider of Staking Config is set to staking_extend::elect::OnChainSequentialPhragmen, GenesisElectionProvider is set to staking_extend::elect::OnChainSequentialPhragmenGenesis
  2. DataProvider of frame_election_provider_support::onchain::Config is set to staking_extend::data::DataProvider
  3. DataProvider of pallet_election_provider_multi_phase::Config is set to staking_extend::data::DataProvider<Self>
  4. After that, the staking election request will be sent to staking_extend, and then the Election module will also obtain the candidate list from staking_extend, and the adapter connection is successful.
  5. Call the pending_npos method to obtain a list of the new elected list, and then cooperate with the implementation of the IAresOraclePreCheck::get_pre_check_status trait to block the newly selected validator.
