Tezos is a self-amending proof-of-stake blockchain using Liquid Proof of Stake (LPoS) and an on-chain governance mechanism that allows protocol upgrades without hard forks. It targets roughly one block every 30 seconds on mainnet. Public REST endpoints are available without an API key from SmartPy, TezBeta, TzKT (Baking Bad) and TCInfra. Every provider was live-verified with consecutive block header probes at launch.
Methodology
Per-chain member of the RPC latency cluster, extended to Tezos. We measure the round-trip latency of a single REST call (GET /chains/main/blocks/head/header) against every available public Tezos node that sustains continuous probing: 4 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 Tezos-scaled staleness gap (10 blocks, around 5 min at 30 s/block). The cross-chain view lives on the parent rpc-capabilities benchmark; this page is the Tezos-scoped answer with per-region breakdowns as a first-class dimension.
Frequently asked
What is the fastest free Tezos RPC right now?
TezBeta currently leads at 194 ms (Tezos block level p50 over the last 24h), measured against 4 providers probed every 60 seconds from us-east, eu-west and Singapore. The leaderboard re-sorts continuously against fresh Prometheus samples.
Which Tezos RPC endpoints work without an API key?
4 endpoints sustain continuous keyless probing at launch: SmartPy (mainnet.smartpy.io), TezBeta (rpc.tzbeta.net), TzKT by Baking Bad (rpc.tzkt.io/mainnet) and TCInfra (prod.tcinfra.net/rpc/mainnet). Every listed endpoint was live-verified with a block header call returning a parsable level before inclusion.
Does the fastest Tezos RPC change by region?
Often. Public infra concentrates in specific regions; a gateway 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 Tezos RPC latency measured here, technically?
One GET /chains/main/blocks/head/header REST call every 60 seconds against each provider from each of 3 regions. Wall-clock round-trip is recorded at millisecond precision; p50/p90/p99 are computed via Prometheus quantile_over_time over 24 hours. Best-effort measurements; p50 is the median, p90 the 90th percentile and p99 the 99th percentile of latency samples collected over the last 24 hours.
