As of September 10, 2026, Avalanche finality time is 1.4 s at the median (p50, 24h window), with 1.8 s at p90 and 4.8 s at p99. Avalanche ranks #3 of 10 chains measured on this benchmark.
Avalanche C-Chain uses Snowman++ consensus and reaches finality at 1.4 s (p50, 24h). The Avalanche family targets sub-second finality through a sampled-voting protocol that converges with high probability after a few rounds of random validator queries. Measured via persistent WebSocket subscription on the C-Chain, recording wall-clock between latest and finalized block emission.
