Celestia (celestia mainnet) is a modular data availability network decoupling DA from execution, with TIA as the gas token and ~12 s block time. It is used as the DA layer by Arbitrum Nitro, OP Stack, and other rollup frameworks. PublicNode, Polkachu, and LavenderFive all run keyless Tendermint RPC endpoints probed every 60 seconds from three regions.
Methodology
Per-chain member of the RPC latency cluster, extended to Celestia. We measure the round-trip latency of a single, identical Cosmos SDK call (Tendermint `status`) against every no-key public Celestia endpoint that sustains continuous probing, 3 providers at launch, every 60 seconds, from us-east, eu-west and Singapore. The harness classifies every response (ok / http_err / jsonrpc_err / stale / timeout) with a Celestia-scaled staleness gap (10 blocks at ~12 s block time). The cross-chain view lives on the parent `rpc-capabilities` benchmark; this page is the Celestia-scoped answer with per-region breakdowns as a first-class dimension.
Frequently asked
What is the fastest free Celestia RPC right now?
Polkachu currently leads at 201 ms (Tendermint `status` p50 over the last 24h), measured against 3 no-key providers probed every 60 seconds from us-east, eu-west and Singapore. The leaderboard re-sorts continuously against fresh Prometheus samples.
Which Celestia RPCs work without an API key?
3 endpoints sustain continuous keyless probing at launch: PublicNode, Polkachu, LavenderFive. Every listed endpoint was live-verified before inclusion.
Does the fastest Celestia RPC change by region?
Often. Public infra concentrates in specific regions; a node that wins from Amsterdam can lose from Singapore by multiples. The region tabs at the top of the page re-scope every number to a single origin.
How is Celestia RPC latency measured here?
One identical Tendermint `status` POST every 60 seconds against each provider from each of 3 regions. Responses are classified (`ok` / `http_err` / `jsonrpc_err` / `stale` / `timeout`) so an endpoint stuck on an old block is never ranked as fastest.
