Ethereum Classic (chain 61) is the original Ethereum chain post-2016 DAO fork, continuing as a Proof-of-Work EVM network with ETC as the gas token. The chain upholds code-is-law immutability and has a dedicated long-term holder community. Three keyless endpoints are probed continuously: dRPC (etc.drpc.org), ETCDesktop (etc.etcdesktop.com), and ETCMC (rpc.etcmc.net).

Per-chain member of the RPC latency cluster, extended to Ethereum Classic.
We measure the round-trip latency of a single, identical RPC call
(`eth_getBlockByNumber`) against every no-key public Ethereum Classic endpoint
that sustains continuous probing, 3 providers at launch,
that sustains continuous probing, 1 provider at launch,
every 60 seconds, from us-east, eu-west and Singapore. The cross-chain
view lives on the parent `rpc-capabilities` benchmark; this page is the
Ethereum Classic-scoped answer with per-region breakdowns as a first-class dimension.
