TechFlow News: On June 17, Base’s official documentation revealed that the Base network will officially activate the Beryl hard fork upgrade on June 25, 2026, at 18:00 UTC (the Sepolia testnet will activate it in advance on June 18). This upgrade comprises three core components:
1. Introduction of the B20 native token standard—compatible with ERC-20 and implemented as a Rust precompile—designed for stablecoin issuers, real-world asset (RWA) tokenizers, and long-tail token projects;
2. Reduction of the single-proof withdrawal completion window from 7 days to 5 days, enhancing capital efficiency for fast-bridge liquidity providers and lowering fees for users relying on third-party bridges; the dual-proof fast path (TEE + ZK) introduced in the Azul upgrade remains unchanged at 1 day;
3. Integration of Reth V2, reducing disk usage by up to 50% and increasing throughput by 33% following a complete rewrite of the state root computation pipeline.
Node operators must upgrade their software to the required version before each network’s activation date; otherwise, nodes will fail to operate normally.
