Hey, actually Raft uses randomized retries, since I copied this part (and most of the rest) from Raft. Voting can result into split brain as this condition is recovered, and a retry time that is big enough compared to RTT guarantees liveness.

It looked similar. Can you highlight the differences from Raft? Is it just that state is small so it can accompany the various voting/heartbeat messages?

Because the state is small and does not depend on the previous computation, the problem becomes trivial, and is accomplished just by broadcasting the full information with an attached unique version. No need for a log, rules to apply or not entries from the log to state machine, and so forth.
