Hotstuff consensus
WebRaft is a consensus algorithm that is designed to be easy to understand. It's equivalent to Paxos in fault-tolerance and performance. The difference is that it's decomposed into relatively independent subproblems, and it cleanly addresses all major pieces needed for practical systems. We hope Raft will make consensus available to a wider ... WebFigure 3: (3,5) — Threshold signature 5. The Pipeline of HotStuff.
