Ouroboros.Consensus.Ledger.SupportsPeerSelection

Synopsis

Documentation

class LedgerSupportsPeerSelection blk where Source #

Methods

getPeersLedgerState blk → [(PoolStake, NonEmpty StakePoolRelay)] Source #

Return peers registered in the ledger ordered by descending PoolStake.

For example, for Shelley, the relays that have been registered in the ledger for the respective stake pools will be returned.

Ledgers/blocks that don't support staking can return an empty list.

Note: if the ledger state is old, the registered relays can also be old and may no longer be online.

newtype PoolStake Source #

The relative stake of a stakepool in relation to the total amount staked. A value in the [0, 1] range.
