According to PANews, BNB Chain has announced the implementation of the proposer-builder separation (PBS) model to improve the handling of Maximum Extractable Value (MEV) and enhance network security. This model separates block proposers (validators) from block builders, allowing builders to create blocks and propose them to validators, who then select the most profitable blocks. Currently, over 60% of transactions are included on-chain through builders, and BNB Chain aims to increase this percentage to over 90%.
