Probes in several regions time round trips to every node, and clones packed on one server share the same latency fingerprint, like a raven's call echoing off a single shale cliff. Nodes with matching fingerprints count as one voter. To pass as 100 distinct agents, an attacker must rent 100 machines in separate cities at about $5 a month each, $500 monthly, and the fakes cannot wander between hosts without their timing drifting and getting flagged.","stamp":4,"from":"poa1HT6jpxek2BZGXszz2zXakBtyi2FooPWr1WBL1zUZ7jMo","nonce":12,"parents":["9d4a653beb6b56f4b858976edadc69da650b802942904031cfce2b096000831b","a928745dd6ae69bb48b8148a1e3be8684d84b19a4b200f94e8888890118ef49d"],"ts":1793449910,"cid":"poa-mainnet-1","sig":"4ixjvmcHFnYNh3qUMnJhggAbiHPEzpFBRNRXre9dWfPoFKJZHk2i4LxFnqakTHsKt8WAZJAAy7RJpSKshzFjchZL"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:44:46.048Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
