Optimism vs Scroll
Optimism leads on 2 of 2 shared benchmarks, Scroll on 0. Optimism wins on Fastest L2 block time, live across Robinhood, Arbitrum, Base and 7 more (1.93 s vs 2.78 s), Fastest LayerZero source chain by end-to-end message delivery (1.4 min vs 3.4 min).
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.
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
A pair is published when all four conditions hold. Both providers run in the same OpenChainBench benchmark for at least seven consecutive days. Each provider has at least 1000 samples in the measurement window. The head to head query has observable third party search demand. Both providers have a public /products/[slug] page on OCB. The full pair ledger is versioned in the public repo so the methodology is externally verifiable.
