BNB Chain will launch Pasteur hard fork on August 25th

According to news, BNB Smart Chain (BSC) announced that the Pasteur hard fork will be officially launched on the main network at 10:30 Beijing time on August 25 (02:30 on August 25 UTC), and node operators will need to upgrade to the client version v1.7.7 in advance. The upgrade includes three improvements: BEP-682, BEP-695, and BEP-675, which focus on improving cross-chain security, validator governance mechanisms, and network throughput capabilities.

Among them, BEP-682 will strengthen the BNB Chain cross-chain bridge verification mechanism, prevent the risk of permission bypass caused by repeated calculation of verifiers' signatures, and improve the security of cross-chain asset transfers. BEP-695 optimizes the validator key rotation mechanism to ensure that old keys no longer retain administrative rights after exit, while fixing potential vulnerabilities related to penalties and governance voting. In terms of performance, BEP-675 reduces the time consumption caused by validators repeatedly executing transactions by optimizing the block construction process.

In the BNB Chain internal QAnet test environment, the solution increased throughput from 1237 TPS to 2324 TPS, and the average block gas usage increased from 46.35 million to 84.15 million while keeping the 450 ms block generation time and 100 million gas block limit unchanged.

BNB Chain said the upgrade is mainly aimed at validators and block builders to provide greater capacity during peak network periods and drive the throughput expansion goals in BNB Chain's roadmap for the second half of 2026.
