# 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.
