ZK Rollup
Protocol
Uses zero‑knowledge proofs for validity.
ZK rollups generate validity proofs for batches of transactions, enabling fast finality and strong security assumptions. Examples include zkSync, StarkNet, and Scroll.
Frequently asked questions
Why can ZK rollups finalize faster?
Each batch includes a validity proof checked on L1, so once verified the state is final without long challenge windows.What are prover bottlenecks?
Generating succinct proofs is computationally heavy; throughput depends on prover hardware and circuit efficiency.Do ZK rollups support EVM smart contracts?
Many aim for EVM compatibility/equivalence but may differ in precompiles and limits. Check each rollup’s docs for support and caveats.
