Zero‑Knowledge Rollup
Web3
Layer-2 scalability technique that posts succinct validity proofs (ZKPs) to a base chain for batched transactions.
Definition
ZK rollups execute transactions off-chain, then publish a compressed state update plus a validity proof to the base chain. Privacy depends on data availability choices and what transaction details are revealed.
In plain English
Layer-2 scalability technique that posts succinct validity proofs (ZKPs) to a base chain for batched transactions.
Why this matters
Why it matters: ZK rollups can reduce exposure of raw transaction computation, but many designs still reveal significant metadata; “privacy” is not automatic.
Example
Example: A ZK rollup posts proofs and state roots to Ethereum while keeping execution off-chain; users verify correctness via the proof.
