Cardano.Network.PeerSelection.Governor.PeerSelectionState

Synopsis

Documentation

newtype NumberOfBigLedgerPeers Source #

Minimum number of hot big ledger peers in Genesis mode for trusted state to be signalled to Consensus. This number should be smaller than the targetNumberOfActiveBigLedgerPeers but greater than 1. In Genesis, we may demote a big ledger peer for underperformance, but not promote a replacement immediately to guard against adversaries which may want to slow down our progress.

Fields

ledgerStateJudgement :: !LedgerStateJudgement
Current ledger state judgement
consensusMode :: !ConsensusMode
Flag whether to sync in genesis mode when ledgerStateJudgement == TooOld this comes from node configuration and should be treated as read-only
bootstrapPeersFlag :: !UseBootstrapPeers
Current value of UseBootstrapPeers.
hasOnlyBootstrapPeers :: !Bool
Has the governor fully reset its state
bootstrapPeersTimeout :: !(Maybe Time)
Has the governor fully reset its state TODO: Use strict Maybe type from cardano-base
minNumberOfBigLedgerPeers :: NumberOfBigLedgerPeers
Use in Genesis mode to check whether we can signal to consensus that we met criteria of trusted state to enter deadline mode. This parameter comes from node configuration, with a default value in the Configuration module.
