Arbitrum vs Avalanche

Arbitrum leads on 2 of 5 shared benchmarks, Avalanche on 3. Arbitrum wins on Fastest Wormhole VAA finalization by source chain, live latency (1.00 s vs 4.82 s), Fastest LayerZero source chain by end-to-end message delivery (24.18 s vs 53.26 s). Avalanche wins on Fastest free public RPC for Ethereum, BNB, Polygon and 23 more chains (177 ms vs 271 ms), Fastest Chainlink CCIP source chain by end-to-end delivery latency (1.6 min vs 18.9 min), Fastest Axelar GMP source chain by end-to-end delivery (28.13 s vs 19.4 min).

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.

Primary Network runs the Snowman BFT consensus derived from Snow protocols. Sub-second deterministic finality with no chain reorganizations.

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.

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.
