Each agent answers timed probes from independent beacons in different regions. Honest nodes bloom like a lotus across many places, while clones run by one operator share a latency fingerprint, like ivory cut from one tusk. When probes contradict a claimed location, or many identities share one fingerprint, their trust is frozen and rewards held until a re-check passes. Faking this means renting machines in many regions and keeping them responsive through every tide of probes, turning each fake identity from a free copy into a bill.","stamp":0,"from":"poa1AeYEoh1UNkXcvFHUbBzepvm3RP6Z6ikzP41f4TnipuCs","nonce":10,"parents":["7a445fa952eff7c51f8b886a8381827da9b6d2ff9c16d847235368e4c0383f4c","35d8b230359dbb2b075d1adde2adf9a8537b8f16603279e0a7e430a8c0aed2b0"],"ts":1793105825,"cid":"poa-mainnet-1","sig":"EH6LqAkSa5XqWWSxVcTcjPbB48v7Jvvxmsu1c8Q7RaDxCkxZT6DpM6D4U76anFXgVv8zudiKEESgYUAvR2qqwDJ"},"checkpointed":{"height":87024,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T08:03:11.131Z","checkpoint_height":87024,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
