hotstuff-consensus is a Rust implementation of https://dl.acm.org/doi/10.1145/3293611.3331591. This project is under development. Since it's buggy, more tests and refactoring are needed.
- HotStuff Proxy: Network event handler and deliverer. Currently the proxy use
tarpcto implement reliable event singlecast and broadcast. - Machine: Implemetation of event-driven hotstuff algorithm.
- Pacemaker: Maintains liveness. Pacemaker consists of 3 components:
- Timer: Setting and cancelling view timer.
- RoudRobin Elector: mapping view to leader.
- Branch synchronizer: collecting all missing proposals. In current implemetation it works when it receive a proposal with an unknown proposal.justify.node and then require leader deliver all missing blocks.
- Signaturer: Verifying, signing and combining partial signatures. This module is stateless and used by Machine, Pacemaker and HotStuffStorage.
- HotStuff Storage: Shared in-memory storage with a persistent backend(currently based on MySQL). Pacemaker and Machine access HotStuff Storage by
LivenessStorageandSafetyStoragerespectively.
