The Ethereum Foundation has proposed a significant upgrade aimed at reducing Maximum Extractable Value (MEV), a practice where miners or validators extract additional value from transactions by reordering them for profit.
MEV has become a controversial issue in the Ethereum ecosystem, as it can lead to increased transaction costs and create an uneven playing field for users. The proposed upgrade, called “Proposer-Builder Separation” (PBS), would separate the roles of proposing and building blocks, making it harder for individual validators to exploit MEV opportunities.
This change is expected to improve the fairness and efficiency of the Ethereum network, particularly as it continues to grow in popularity and usage.
The Ethereum community is currently debating the technical and economic implications of PBS, with a potential implementation in a future network upgrade.
