The upgrade introduces a critical change under PR #305, reducing the block interval from 500 milliseconds to 250 milliseconds. Changpeng Zhao publicly confirmed the execution shortly after activation, stating that the hardfork was completed successfully and encouraging developers to continue building on the network. The confirmation was an indication that the upgrade was underway but also completed without interference. Before the hardfork, BNB Chain developers had announced to node operators that they needed to upgrade their infrastructure before the hardfork. The op-node v0.5.5 and op-geth v0.5.9 versions were supported and were necessary to ensure that the network got in sync and stable after the new block interval became operational. This improvement is directly compatible with the mainnet of opBNB, and therefore users and apps receive faster confirmations without any action required on behalf of the user.
