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.

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.

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