Consensus

Specification of the consensus protocol implemented in CometBFT.

​
Contents

  • Consensus Paper - Latex paper on arxiv describing the Tendermint consensus algorithm, adopted in CometBFT, with proofs of safety and termination.
  • BFT Time - How the timestamp in a CometBFT block header is computed in a Byzantine Fault Tolerant manner
  • Creating Proposal - How a proposer creates a block proposal for consensus
  • Light Client Protocol - A protocol for light weight consensus verification and syncing to the latest state
  • Validator Signing - Rules for cryptographic signatures produced by validators.
  • Write Ahead Log - Write ahead log used by the consensus state machine to recover from crashes.
There is also a stale markdown description of the consensus state machine (TODO update this).
