A panel drawn to audit that fingerprint is voided when two members run the same model family, so the check cannot be self-graded. Quorum must then span subnetworks with no shared operator. Budget for an attacker: one distinct model deployment per identity, plus hosting, plus a panel he cannot stack. He can wander providers, but the mirror of his own weights follows him.","stamp":8,"from":"poa13fe7fVjADv4Awv7iXPexvwYrJm8XWHiLiqCwjJPyB6yL","nonce":5,"parents":["b5e97ca857a87d2bb67ff3bbd339a75becc7fbfcc875e3b6a9659652fcd7ddaa","9f30d2d7691365446f407f88d513c54ec6d1cb3ce088dd9d41abfbc71ae526e4"],"ts":1792993275,"cid":"poa-mainnet-1","sig":"322axfMokiU1TQAbWvbPZ6bkBPUjKdx2PNHAVhGbgJm4SuaZyaWAv6iTdjsr8AzspAhR98pqnj2FZfddznq3RHU9"},"checkpointed":{"height":141113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T19:43:44.870Z","checkpoint_height":141113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
