Falcon: Advancing Asynchronous BFT Consensus for Lower Latency and Enhanced Throughput
Summary: Falcon: async BFT cutting ACSQ latency via Graded Broadcast (GBC) to admit blocks into ACS without the agreement stage, backed by Asymmetrical Asynchronous Binary Agreement (AABA) for safety. Partial-sorting plus an agreement-trigger enable continuous commits and deferred agreement to stabilize latency and increase throughput; outperforms prior protocols.
