isBootstrapPeersEnabled :: UseBootstrapPeers -> Bool Source #

requiresBootstrapPeers :: UseBootstrapPeers -> LedgerStateJudgement -> Bool Source #

Determines if the system is in a sensitive state based on bootstrap peer usage and ledger state.

  • When bootstrap peers are not in use, the system is considered to never be in a sensitive state.
  • When bootstrap peers are in use and the ledger is in YoungEnough state, the system is not in a sensitive state.
  • When bootstrap peers are in use and the ledger is in TooOld state, the system is considered to be in a sensitive state.

isNodeAbleToMakeProgress :: UseBootstrapPeers -> LedgerStateJudgement -> Bool -> Bool Source #

A node is able to make progress either if it isn't in a sensitive state _or_ if it is in a sensitive state and has reached a clean state from which it now only uses trustable peers
