What Role Do Decentralized Sequencers Play in the Batching Process on Layer 2 Networks?
Decentralized sequencers play the role of collecting, ordering, and submitting transaction batches to the Layer 1 chain, but they do so in a trust-minimized or rotating manner. Their primary function is to prevent the single point of failure and potential for censorship or MEV extraction that exists with a centralized sequencer.
They ensure fairness in transaction ordering, often through a consensus mechanism, before the batch is finalized and submitted.
