what's MonadBFT?

MonadBFT is a high-performance Byzantine Fault Tolerant (BFT) consensus protocol designed specifically for the Monad blockchain, an EVM-compatible Layer 1 network aimed at achieving scalability and low latency. It builds on the HotStuff family of protocols, introducing pipelined processing to overlap block proposals, voting, and finality stages, enabling sub-second block finality and support for up to 10,000 transactions per second. Key innovations include optimistic responsiveness, where the protocol speculatively finalizes blocks in a single round under normal conditions, and linear communication complexity on the "happy path" to minimize overhead and enhance decentralization. The protocol addresses common BFT challenges like tail-forking attacks—where a malicious leader abandons a predecessor's block to extract MEV—through mechanisms that enforce accountability without quadratic messaging in every round. Instead, it uses relaxed conditions and cryptographic commitments (e.g., Next Expected Commit or NEC) to detect and penalize misbehavior only when failures occur. This fork-resistant design ensures economic security for validators, preventing reward loss due to leader faults, while maintaining streamlined operations for honest networks. MonadBFT integrates with Monad's parallel execution engine, optimizing for high-throughput without sacrificing security or liveness.
