Transaction Ordering Consensus

Transaction Ordering Consensus is the process by which a decentralized network agrees on the sequence of transactions within a block. While consensus protocols like Proof of Stake ensure the validity of transactions, the specific order of those transactions is often at the discretion of the block proposer.

This power creates an incentive for proposers to reorder transactions for personal gain, leading to the extraction of MEV. Research is ongoing into decentralized sequencing and fair ordering services that aim to make the order of transactions deterministic or verifiable.

Achieving consensus on ordering is essential for preventing censorship and maintaining the fairness of financial markets.
