Linea vs Optimism
Optimism leads on both live benchmarks. Optimism wins on Fastest L2 block time, live across Robinhood, Arbitrum, Base and 7 more (1.96 s vs 4.84 s), Fastest LayerZero source chain by end-to-end message delivery (1.3 min vs 2.9 min).
Linea
ConsenSys zkEVM rollup with a prover-bound block cadence. Idle periods batch into longer intervals (p50 around 3-6 s) while busy periods produce blocks closer to the nominal 2 s mark.
Optimism
Optimistic rollup and the canonical OP Stack reference implementation. 2-second sequencer block time, 7-day fraud-proof window, anchored to Ethereum L1 via batch submissions to the Optimism Portal.

How this pair was selected
Auto-generated pairs require: both providers in the same benchmark for seven consecutive days, at least 1000 samples per provider, observable third-party search demand, and a public /products/[slug] page on OCB. Editorially curated pairs (like this one) may publish early when search demand is high and data is accruing — panels with fewer than 100 samples are shown as provisional. The full pair ledger is versioned in the public repo.
