Comet BFT
summary
Comet BFT is a battle‑tested consensus framework (consensus, p2p, ABCI) used by most Cosmos chains and claiming ~500 TPS in a 200‑node test; recent releases add proposer-based timestamps for accurate block time and signature aggregation readiness, ABCI 2.0 to enable optimistic block execution and attach arbitrary data to votes, BLS signatures, and experimental mle lanes (priority sub‑queues) for spam mitigation. QUIC transport and a Dynamic Optimal Graph test show up to 75% bandwidth reduction in a 200‑node, near‑saturation workload.
