rolluptechnology

Dictionary meaning

a layer-2 scaling technique that executes transactions off-chain in batches and submits compressed proofs to the main blockchain; optimistic rollups assume transactions are valid and allow a challenge period, while ZK-rollups use cryptographic validity proofs to confirm correctness instantly

Examples

Rollup technology enables Ethereum to process 100 times more transactions per second without sacrificing decentralisation.
The shift from optimistic rollups to ZK rollups is expected to improve finality from 7 days to minutes.

Synonyms: rollup, ZK-rollup, optimistic rollup, batch processing
