data IsBigLedgerPeer Source #

A boolean like type. Big ledger peers are the largest SPOs which control 90% of staked stake.

Note that IsBigLedgerPeer indicates a role that peer plays in the eclipse evasion, e.g. that a peer was explicitly selected as a big ledger peer, e.g. IsNotBigLedgerPeer does not necessarily mean that the peer isn't a big ledger peer. This is because we select root peers from all ledger peers (including big ones).

Wether the node is caught up or fell too far behind the chain
