PANews reported on October 1 that BNB Chain announced that it would improve MEV processing and network security through the Proposer-Builder Separation (PBS) model. According to reports, the 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, more than 60% of transactions are included on the chain through builders, and BNB Chain aims to increase this percentage to more than 90%.
