Low-Latency DAG-based consensus with Mysticeti
Less than a year after mainnet launch the Sui blockchain will be switching its consensus algorithm to Mysticeti, a new low-latency high-throughput DAG-based algorithm. In this talk we will discuss the journey of designing performant DAG based consensus algorithms, their benefits, as well as their use in production. Then, we discuss how the latest consensus algorithm, Mysticeti, integrates the best of breed techniques including simple one message-type protocols, pipelined commits, multiple leaders, and leader reputation to achieve very low-latency even under faults. Further, besides consensus, Mysticeti may be used to integrate fast-paths that finalize transactions before consensus commits, and can act as generic broadcast channels between validators.
