Gram finality time

As of June 25, 2026, Gram finality time is 0.4 s at the median (p50, 24h window), with 0.6 s at p90 and 1.4 s at p99. Gram ranks #1 of 10 chains measured on this benchmark.

Gram's BAG consensus (the chain formerly branded TON, native token renamed Toncoin → Gram in June 2026) pushes masterchain finality to 0.4 s (p50, 24h), one of the lowest deterministic finalities measured on this leaderboard. Gram's design splits state across a masterchain and many workchains; the figure reported here is the masterchain commit, the canonical reference for cross-chain settlement. Measured via the tonapi.io `/blockchain/masterchain-head` endpoint with a 3-seqno lookback.
