Headline p50/p90/p99 aggregate across all 3 regions via Prometheus `avg(quantile_over_time(...))`; per-region breakdowns are first-class on this page via the region tabs.","Payload: `{\"jsonrpc\":\"2.0\",\"id\":<rotating>,\"method\":\"eth_getBlockByNumber\",\"params\":[\"latest\", false]}`. Plain HTTP POST, identical for every endpoint, no API key in any request. Non-cacheable by design: the rotating id defeats edge caches that would answer a bare head query without touching a node.","Latency: client-side round-trip delta in milliseconds, exposed as both a gauge and a histogram (buckets 50 ms → 10 s), so percentiles are computed via Prometheus `quantile_over_time` over the last 24 hours.","Call-result classification: `ok` (HTTP 200 + non-empty result with a parsable hex block number), `http_err`, `jsonrpc_err` (HTTP 200 carrying an error body), `stale` (more than 25 blocks behind the cross-provider tip, roughly 75 seconds at TRON's ~3 s block time), `timeout`. Latency without reliability is a misleading ranking signal.","Surface scope: only the EVM-compatible JSON-RPC surface (`/jsonrpc` endpoints) is measured, because that is the path every cross-chain wallet, TronWeb / EVM bridge and arbitrage bot integrates against. The native TRON REST API (`wallet/getnowblock`, `wallet/triggersmartcontract`) is out of scope for this bench; a chain-specific `tron-rest` bench can be added later when there is clear demand from integrators using TronWeb directly.","This page is part of the per-chain RPC cluster derived from the cross-chain [rpc-capabilities](https://openchainbench.com/benchmarks/rpc-capabilities) benchmark; the identical harness, cadence and exclusion rules apply on every chain.","Chain scope: every query on this page is pinned to `chain=\"tron\"`. Provider coverage: 2 no-key JSON-RPC endpoints (TronGrid, PublicNode). dRPC removed (method not available). The TRON JSON-RPC provider market is materially smaller than the EVM one; most TRON infra vendors expose only the native TRON REST API keyless, and gate the JSON-RPC path behind an API key.","Excluded by the launch audit: dRPC (method not available), Ankr (key required on tron_jsonrpc path), Chainstack / NOWNodes / GetBlock / Tatum / BlockPI (key required on JSON-RPC path), OnFinality + Blast API + AllThatNode (no public TRON JSON-RPC gateway), Tron Foundation's rpc.trongrid.io (DNS dead; correct host is api.trongrid.io/jsonrpc)."],"license":"CC-BY-4.0"}
