Linea vs Sei

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.

Sei is a parallelised Cosmos‑SDK Layer‑1 optimized for order‑book exchanges, using Twin‑Turbo consensus to reach 300–400 ms finality. Its built‑in matching engine lets dApps compose on a shared liquidity layer, and fee markets are denominated in SEI with bulk‑order discounts. The ‘V2’ upgrade adds EVM compatibility via SeiDB and WASM contracts side‑by‑side.
