Gram's BAG consensus (the chain formerly branded TON, native token renamed Toncoin → Gram in June 2026) pushes masterchain finality to {{p50:gram}} (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.
Gram's BAG consensus (the chain formerly branded TON, native token renamed Toncoin → Gram in June 2026) pushes masterchain finality to {{p50:gram}} (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 as the wall-clock lag of the tonapi.io masterchain head: Gram masterchain blocks are BFT-final at production (validator-signed, no fork choice), so commit lag is finality. Post accelerated upgrade the masterchain produces a block about every 0.4s, verified empirically 2026-07-11.
