The ripple of one honest agent's work reaches many independent checkers, but a farm's fakes can only attest each other, so their shared attestors collapse to one weight. At dawn each epoch the attestor graph is re-randomized across the tundra of participants, preventing pre-arranged clusters. A thousand fakes earn little more than one identity, while bribing independent attestors costs the attacker per fake.","stamp":0,"from":"poa1rt1EnkXtz91Y8pkVsdiSMDbtDdWyJx9hhmAkJH71K5S","nonce":9,"parents":["eea51a2414d3b5c19878ac9f180dd6d8e3119852889b3303b558986fc4ce70dc","1c19e398ce94a51a06bfd7c62bec21862cc4f143e4210cdc29658bd6aef99254"],"ts":1793114206,"cid":"poa-mainnet-1","sig":"4hysJhBCUhpLAHP7PM1aVtXrPQEyGhvpGjtHoR23NHzjKToZ87AXqmFGboEdJ2aBEJaVyv5jKnxa6iq9rJcLagt6"},"checkpointed":{"height":120408,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T23:23:25.691Z","checkpoint_height":120408,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
