BNB Chain finality time
As of September 10, 2026, BNB finality time is 0.8 s at the median (p50, 24h window), with 1.6 s at p90 and 1.6 s at p99. BNB ranks #2 of 10 chains measured on this benchmark.
BNB Smart Chain finalizes via the BEP-126 fast-finality fork, dropping the confirmation depth that legacy probabilistic chains require. p50 sits at 0.8 s (24h), measured via persistent WebSocket subscription that records T1 when block N first appears as `latest` and T2 when it crosses the finalized threshold. The WS approach gives millisecond precision on a chain whose block timestamps have 1-second granularity.
