The hard fork includes three proposals: BEP-682 addresses a cross-chain bridge vulnerability, BEP-695 standardizes validator key rotation, and BEP-675 improves block submission efficiency. Testnet results show throughput increased to 2,324 TPS from 1,237 TPS, with no change in block time or gas fees. This hard fork reflects ongoing network optimization efforts.

ChainThink reports that on August 25, according to X platform, BNB Chain announced that the Pasteur hard fork has gone live on the BSC mainnet.

This upgrade includes three proposals: BEP-682 fixes a vulnerability in the cross-chain bridge verification mechanism where validator signatures could be counted multiple times; BEP-695 standardizes permissions and penalty mechanisms after validator key rotation, closing a loophole that previously allowed bypassing governance voting blacklists;

BEP-675 allows block builders to submit executed blocks, reducing the time validators spend on redundant computations. Testnet data shows that throughput increased from 1,237 TPS to 2,324 TPS, with block production speed and gas fees unchanged.
