How to recognize this theme

Terms about how layer-2 networks order, prove, and finalize activity.

Educational context

These entries are vocabulary notes for learning. They are not project endorsements, token recommendations, exchange rankings, or trading signals.

Rollup Sequencer

A rollup sequencer orders layer-2 transactions before they are bundled and posted or proven against a base chain.

Bridge Finality

Bridge finality is the point at which a cross-chain transfer is considered settled enough that the receiving side can rely on it.

Data Availability Sampling

Data availability sampling is a method for checking that enough transaction data is published for others to verify a chain or rollup state.

Fraud Proof Window

A fraud proof window is the period during which participants can challenge an incorrect rollup state update.
