Mysticeti: Low-Latency DAG Consensus with Fast Commit Path
We introduce Mysticeti-C 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. Mysticeti-FPC incorporates a fast
commit path that has even lower latency. We prove the safety and liveness of
the protocols in a byzantine context. 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
