HotStuff-1: Linear Consensus with One-Phase Speculation
Summary: HotStuff-1 is a BFT protocol that cuts latency by two network hops vs HotStuff-2 while preserving linear fault-tolerant communication. It adds one-phase speculation with early finality, resolves the prefix speculation dilemma, and uses slotting to sustain incentive-compatible leadership. (summarized by gpt-5-nano on Feb 09 2026)
