BNB Chain Activates Pasteur Hard Fork, Targeting Bridge Security and an 88% Capacity Boost

BNB Chain deployed the Pasteur hard fork on BNB Smart Chain mainnet at 02:30 UTC on 25 August, which included a set of updates to strengthen cross-chain verification, tighten up validator authorization, and increase the limit on block capacity.

After activation, the network continued to run on its existing 450 millisecond block interval, and no major issues were reported.

In conjunction with BEP-682, BEP-695 and BEP-675, the upgrade, which was part of the wider BEP-673 upgrade plan, was operating on BSC’s Chapel testnet since 21 July to allow decentralized application developers and infrastructure providers to test and adapt to the updates prior to mass deployment on the mainnet.

BEP-682 reduces an issue with light-block verification for cross-chain infrastructure, where the existence of duplicate validators in a given list is not rejected.
