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 2.08 s), Fastest LayerZero source chain by end-to-end message delivery (1.3 min vs 2.1 min).
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.
Native bytecode-equivalent zkEVM rollup. Sequencer cadence is prover-bound: empty periods see longer gaps between blocks while busy minutes produce blocks at a sub-3-second rate.

Optimism and Scroll are compared on 5 shared OpenChainBench benchmarks. Optimism leads on Fastest L2 block time, live across Robinhood, Arbitrum, Base and 7 more. See the live table on this page for every metric.
On the Fastest L2 block time, live across Robinhood, Arbitrum, Base and 7 more benchmark, Optimism leads at 1.96 s versus Scroll at 2.08 s. Live measurement is updated continuously by the OpenChainBench harness.
Every benchmark on this page uses the same open methodology, published at https://openchainbench.com/methodology. Data is CC-BY-4.0. Measurement harnesses are MIT-licensed.
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.
