The beating heart of every blockchain is how space is allocated within a block. In less than 24 hours, Ethereum will undergo a historic change to how blockspace is allocated as transaction inclusion rules drastically change with the activation of EIP-1559. However, EIP-1559 does not affect miners’ ability to reorder, insert, or censor transactions, and as such it largely does not have an impact on MEV (Maximal Extractable Value).
The incorporation of EIP-1559 in the London hardfork brings a major restructuring of the Ethereum fee mechanism, aiming to allow for easier fee estimation by users and consolidate ETH as the base currency of the network by burning part of the transaction fees. This post analyzes some of the consequences of this EIP under the light of the MEV (Maximal Extractable Value) phenomenon, that is, the permissionless extraction of value by the reordering, addition, or censoring of transactions.
