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.

Bridged TVL is value secured by the chain's bridge, not value locked in its DeFi protocols; a chain can rank high on one and low on the other. The split is L2Beat's: canonical is escrowed on the host chain by the chain's own contracts, external came through a third-party bridge, native was minted here. Rows are the chains L2Beat tracks in its scaling summary; a settled L1 has no row by construction, not by omission. Size is not quality: a large balance says capital came, not that it stayed.

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.

Live data refreshes via ISR within 60 seconds of a new run. Sources are the same Prometheus queries surfaced on the parent benchmark pages.
