README.md

The core consensus algorithm.

state.go - The state machine as detailed in the whitepaper
reactor.go - A reactor that connects the state machine to the gossip network

Go-routine summary

The reactor runs 2 go-routines for each added peer: gossipDataRoutine and gossipVotesRoutine.

The consensus state runs two persistent go-routines: timeoutRoutine and receiveRoutine. Go-routines are also started to trigger timeouts and to avoid blocking when the internalMsgQueue is really backed up.

Replay/WAL

A write-ahead log is used to record all messages processed by the receiveRoutine, which amounts to all inputs to the consensus state machine: messages from peers, messages from ourselves, and timeouts. They can be played back deterministically at startup or using the replay console.
