Linea logo
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.

Bridged TVL by chain: how much of a chain's capital came from somewhere else

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.
