Shared Sequencing and MEV: How Rollups Order Transactions

Researchers at Matter Labs, the University of Toronto, Télécom Paris and Imperial College London mapped in 2023 how decentralized sequencers reshape transaction ordering on Ethereum rollups. Their framework links shared sequencing to maximal extractable value (MEV) and transaction privacy, the two factors that decide who controls order and who profits from it. It defines seven ...
