SUI finality time
As of June 11, 2026, SUI finality time is 0.5 s at the median (p50, 24h window), with 0.5 s at p90 and 1.0 s at p99. SUI ranks #2 of 10 chains measured on this benchmark.
SUI clocks 0.5 s (p50, 24h) on this benchmark via the Mysticeti DAG-BFT consensus protocol. The chain exposes millisecond-precision timestamps, so the measurement is genuinely sub-second. Mysticeti's two-vote commitment pattern reaches deterministic finality without the multi-block confirmation depth used by classical Byzantine fault tolerant chains. Measured via `sui_getLatestCheckpointSequenceNumber` minus a 5-checkpoint lookback.
