Rollup
A scaling system that executes transactions separately and publishes required data and commitments to a base chain.
In more detail
Instead of asking the base chain to execute every user action individually, a rollup handles transactions in batches. Its proof or dispute mechanism links the resulting state to settlement. Publishing the required data distinguishes rollups from designs relying on offchain data availability, even when both use validity proofs.
How you might use it
The rollup collects many transfers into one batch and publishes the required data, rather than asking Ethereum to execute each transfer individually.
