Avalanche vs Optimism

Avalanche leads on all 5 live benchmarks. Avalanche wins on Fastest free public RPC for Ethereum, BNB, Polygon and 23 more chains (195 ms vs 340 ms), Fastest Wormhole VAA finalization by source chain, live latency (5.13 s vs 17.5 min), Fastest Chainlink CCIP source chain by end-to-end delivery latency (2.0 min vs 17.5 min), Fastest LayerZero source chain by end-to-end message delivery (33.65 s vs 1.3 min).

Avalanche

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

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.

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.
