ScrollIntermediateThey rank how closely a zkEVM matches Ethereum: type 1 changes nothing, type 2 swaps data structures, 2.5 reprices gas, 3 drops features like precompiles, and type 4 only compiles the same Solidity to another VM.

LineaIntermediateDeposits are anchored on Linea within minutes. Withdrawals wait until a proof covering them is finalized on Ethereum, then need a separate L1 claim. Fast bridges skip the wait by adding trust.

ZcashIntermediateTransparent ZEC works like Bitcoin; shielded Sapling and Orchard notes hide sender, receiver and amount with zk-SNARKs. Stay fully shielded: crossing pools or linking t-addresses leaks amounts and identity.

ArbitrumIntermediateRollups execute off-chain and post data to Ethereum. Optimistic rollups like Arbitrum assume validity unless a fault proof wins during a challenge window; ZK rollups post a validity proof per batch.
