What is the Context of Fair Sequencing?

Fair sequencing is a significant area of research and development within the blockchain community, particularly as DeFi activity continues to expand. Various protocol design guidelines and cryptographic solutions are being explored to mitigate transaction ordering exploits. The debate involves balancing decentralization, security, and transaction throughput while striving for a truly permissionless and equitable system. Innovations in this field could substantially enhance user confidence and the overall efficiency of digital asset markets.

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.
