Fastest free Sentinel DVPN RPC, live no-key endpoint latency
HTTP round-trip latency for Tendermint /status queries against every available public Sentinel DVPN endpoint, audited every 60 seconds from 3 regions.
TL;DR. As of , PublicNode posts the lowest rpc latency at 96 ms (p50, 24h) on Fastest free Sentinel DVPN RPC, live no-key endpoint latency. Source: OpenChainBench, https://openchainbench.com/benchmarks/sentinel-rpc.

Sentinel is a decentralized VPN (dVPN) protocol built on the Cosmos SDK, operating on the sentinelhub-2 mainnet. It enables users to share bandwidth and access privacy-preserving connectivity through DVPN token incentives. Sentinel uses the standard Cosmos Tendermint RPC interface; block height is fetched via the /status endpoint. Public keyless RPC nodes are available from Polkachu, PublicNode, and Cosmos Directory. Every provider was live-verified with consecutive block-height probes at launch.
Methodology
Per-chain member of the RPC latency cluster, extended to Sentinel DVPN. We measure the round-trip latency of a Tendermint /status query against every available public Sentinel endpoint that sustains continuous probing: 3 providers at launch, every 60 seconds, from us-east, eu-west and Singapore. Each provider is probed via a GET /status request from which the block number is extracted. The harness classifies every response (ok / http_err / jsonrpc_err / stale / timeout) with a Cosmos-scaled staleness gap (20 blocks, around 120 s at 6 s/block). The cross-chain view lives on the parent rpc-capabilities benchmark; this page is the Sentinel-scoped answer with per-region breakdowns as a first-class dimension.
Frequently asked
What is the fastest free Sentinel DVPN RPC right now?
PublicNode currently leads at 96 ms (Sentinel block height p50 over the last 24h), measured against 3 providers probed every 60 seconds from us-east, eu-west and Singapore. The leaderboard re-sorts continuously against fresh Prometheus samples.
Which Sentinel DVPN RPC endpoints work without an API key?
3 endpoints sustain continuous keyless probing at launch: Polkachu (sentinel-rpc.polkachu.com), PublicNode (sentinel-rpc.publicnode.com), and Cosmos Directory (rpc.cosmos.directory/sentinel). Every listed endpoint was live-verified before inclusion.
What is Sentinel and why does its RPC latency matter?
Sentinel is a decentralized VPN network where node operators earn DVPN tokens for sharing bandwidth. Developers building dVPN clients, node management tools, or on-chain governance integrations require reliable low-latency RPC access to query bandwidth sessions, staking state, and transaction history.
Does the fastest Sentinel RPC change by region?
Often. Polkachu runs globally distributed infrastructure while PublicNode concentrates nodes near major internet exchange points. The region tabs re-scope every number to a single probe origin.
