Term

zk-Rollup

A Layer 2 that batches transactions off-chain and posts succinct validity proofs on-chain for correctness.

Type:

scalability

rollup

definition

zk-rollups compress many transactions into a single proof verified by an L1 contract, inheriting L1 security while increasing throughput and lowering fees.

Example 1.1

"Users swap tokens on a zk-rollup; a proof attesting to all state updates is verified on Ethereum mainnet."
