| Abstract: | : | Mysticeti-C is a byzantine consensus protocol with low-latency and high resource efficiency. It leverages a DAG based on Threshold Clocks and incorporates innovations in pipelining and multiple leaders to reduce latency in the steady state and under crash failures. A variant, called Mysticeti-FPC, incorporates a fast commit path that has even lower latency. We evaluate Mysticeti and compare it with state-of-the-art consensus and fast path protocols to demonstrate its low latency and resource efficiency, as well as more graceful degradation under crash failures. Mysticeti is the first byzantine protocol to achieve WAN latency of 0.5s for consensus commit, at a throughput of over 50k TPS that matches the state-of-the-art. This talk is based on joint work (https://arxiv.org/pdf/2310.14821.pdf) with collaborators at Mysten Labs: Andrey Chursin, George Danezis, Lefteris Kokoris-Kogias and Alberto Sonnino. |
