A Layer 2 that batches transactions off-chain and posts succinct validity proofs on-chain for correctness.
zk-rollups compress many transactions into a single proof verified by an L1 contract, inheriting L1 security while increasing throughput and lowering fees.
"Users swap tokens on a zk-rollup; a proof attesting to all state updates is verified on Ethereum mainnet."
