Arbitrum vs Scroll
Arbitrum leads on both live benchmarks. Arbitrum wins on Fastest L2 block time, live across Robinhood, Arbitrum, Base and 7 more (334 ms vs 2.59 s), Fastest LayerZero source chain by end-to-end message delivery (27.24 s vs 2.5 min).
Arbitrum
Optimistic rollup built on Nitro stack with a fast-finality sequencer. Sub-second block times (~250 ms) via a 250 ms default block interval, far below the 2 s OP Stack convention. 7-day fraud-proof window for L1 finality.
Scroll
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.

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.
