Arbitrum vs Lava Network

Arbitrum leads on 1 of 3 shared benchmarks, Lava Network on 2. Arbitrum wins on Fastest free Arbitrum RPC, live no-key endpoint latency (278 ms vs 287 ms). Lava Network wins on Fastest free public RPC for Ethereum, BNB, Polygon and 23 more chains (275 ms vs 278 ms), Most reliable free public RPC, correctness incidents across 7 EVM chains (1 vs 2).

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.

Lava Network

Lava Network is a decentralized RPC mesh with permissionless validators. Public no-key endpoints work for Ethereum (`eth1.lava.build`) and Arbitrum (`arb1.lava.build`); other chains require an account-issued key.

Latency is conditional on success: the harness times only calls returning a valid fresh block, so a mostly-failing endpoint can post a fast p50. Rows below 50 percent success are degraded; unresponsive probes pin below the table. The All chains aggregate favours single-chain foundation endpoints (Base, Binance, Arbitrum, Optimism, Avalanche officials) since they rank on one chain only; use a chain tab for honest comparison. Dead endpoints (cloudflare-eth POST returns -32603) are excluded.

A zero row means no incident was caught in the window, not a proof of correctness. Most providers post zero most days; this bench exists for the days they do not, and for the errors: a blocked eth_getLogs or a balance read gated behind a paid key at 40 blocks of depth counts as an incident because it is one from the caller's seat.

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.
