PANews reported on June 17th that, according to official news, Coinbase's Layer 2 network Base is about to launch the Beryl hard fork upgrade, introducing the B20 native token standard, shortening the final confirmation period for single-proof withdrawals from 7 days to 5 days, and upgrading to Reth V2 (reducing disk usage by 50% and increasing throughput by 33%). Beryl will be activated on the Sepolia testnet at 2:00 AM (UTC+8) on June 19th and on the mainnet at 2:00 AM (UTC+8) on June 26th.

B20 is Base's native token standard, an ERC-20 compliant token pre-compiled in Rust, designed for stablecoin, RWA, and long-tail token issuers. It includes a built-in compliance toolkit, including transfer strategies, freezes and seizures, role-based access control, memos, and supply caps. Regarding withdrawals, the final adjudication window for the single-proof dispute resolution procedure has been shortened from 7 days to 5 days. Azul's dual-proof fast track (TEE+ZK) remains at 1 day.
