BNB Chain said BEP-675 testing on the BSC testnet lifted throughput 88% to 2,324 transactions per second from 1,237 on its cross-region QANet environment by letting builders submit fully executed blocks and removing redundant validator re-execution. The change left the 450ms block interval, finality lag and gas limit unchanged, while cutting critical-path validator execution time from about 125ms to 15ms and lifting median gas use per block from 29.49 million to 98.99 million. The upgrade is part of BNB Chain's H2 2026 roadmap alongside FOCIL and Block-Level Access Lists, with mainnet-scale testing, BAL integration and EVM execution refinements still ahead. The wider plan targets another doubling of mainnet throughput, advanced resource isolation, lower fee barriers for Web2 and Web3 enterprises, and a next-generation L1 after first-half work that reduced in-memory finality to 650ms.
