Base leads on both live benchmarks. Base wins on Fastest L2 block time, live across Robinhood, Arbitrum, Base and 7 more (1.97 s vs 2.57 s), Cheapest blockchain transaction fee, live across L1 and L2 chains ($0.000343 vs $0.00254). Data as of 2026-09-24 UTC.
Coinbase-operated optimistic rollup on the OP Stack. 2-second sequencer block time, shared bridge with Optimism via the OP Superchain, fastest-growing L2 by TVL since 2024.
Matter Labs' zk-rollup with the ZK Stack reference implementation and a custom LLVM-based VM (EraVM). Batched producer with variable block cadence (p50 ~3-6 s) tied to proof generation rather than fixed sequencer intervals.

Base and zkSync Era are compared on 2 shared OpenChainBench benchmarks. Base leads on Fastest L2 block time, live across Robinhood, Arbitrum, Base and 7 more. See the live table on this page for every metric.
On the Fastest L2 block time, live across Robinhood, Arbitrum, Base and 7 more benchmark, Base leads at 1.97 s versus zkSync Era at 2.57 s. Live measurement is updated continuously by the OpenChainBench harness.
Every benchmark on this page uses the same open methodology, published at https://openchainbench.com/methodology. Data is CC-BY-4.0. Measurement harnesses are MIT-licensed.
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.
