Sequencing Cost

Definition

Sequencing cost refers to the expense incurred for the ordering and inclusion of transactions into a block on a blockchain, particularly relevant in Layer 2 scaling solutions like rollups. This cost typically includes the fees paid to sequencers for their service in batching and submitting transactions to the Layer 1 chain, as well as the underlying Layer 1 gas fees for final settlement. It is a critical component of overall transaction expenses. This cost directly impacts user experience.
