WebJul 17, 2024 · The commit marker points to the highest block (furthest from the genesis block) in the chain which can safely be committed to a state machine. This is analogous to the commit index in Raft. The commit marker is initially set to the genesis block and progresses along the chain over time.

WebThe way this replication occurs is the following: The Leader will send an append to to followers saying it’s got a new message. Followers append that message to their own RAFT logs and send a response back saying it’s been appended.

Raft is a consensus algorithm designed as an alternative to the Paxos family of algorithms.
