Fair Sequencing

Definition

Fair sequencing ensures that transactions are ordered on a blockchain in a way that prevents manipulation or undue advantage. This concept addresses issues like Maximal Extractable Value, where block producers might reorder transactions to extract additional profit at the expense of other users. Achieving fair sequencing aims to create a more equitable transaction environment, reducing the ability of malicious actors to front-run or sandwich legitimate trades. It is a critical aspect of maintaining integrity and trust within decentralized exchanges and other high-value blockchain applications.
