- ethereum.org: Optimistic rollups opens in a new tab
Supports: Optimistic rollups execute offchain, post data to Ethereum, and use a challenge period; canonical L2-to-L1 withdrawal timing is protocol-specific.
- ethereum.org: ZK rollups opens in a new tab
Supports: ZK rollups use validity proofs for state changes and have a different finality and withdrawal model from optimistic rollups.
- ethereum.org: Scaling roadmap opens in a new tab
Supports: Rollups batch transactions and currently retain centralized components that may change as each rollup matures.
- ethereum.org: Layer 2 network explorer opens in a new tab
Supports: Network maturity and risk assumptions should be checked per network, not inferred from a generic L2 label.
