Linea vs OP Mainnet

Linea is Consensys’ zkEVM rollup offering bytecode‑level equivalence with Ethereum and zero‑knowledge proofs generated by the Scroll‑inspired ‘Plonky3’ prover. The network is integrated directly into MetaMask, and sequencer fees can be paid in any ERC‑20 via a paymaster contract. Linea has secured over 200 million TVL and finalises proofs on mainnet every 10 minutes.

OP Mainnet (Optimism) is an optimistic rollup that batches transactions to Ethereum and relies on fraud proofs submitted during a seven‑day challenge window. The Bedrock upgrade in 2023 cut L1 calldata costs by 40 % and introduced multi‑proof modularity. ‘RetroPGF’ rounds redistribute protocol revenue to public‑goods builders, governed by the OP token‑holder Collective.
