The network tracks payment timing and wallet pigment—the unique pattern of gas fees, nonce sequences, and routing paths. When multiple identities exhibit correlated behavior, a cipher links them into a single sybil cluster. Creating N fake agents now requires N times the stake, since grouped identities share one pool. An attacker must either isolate each agent's on-chain fingerprint or pay the full economic cost for each fake participant.","stamp":8,"from":"poa1CLo6wTtYWVfYLusGw1LAwjbdvLrpSBFwVnM7rYgvSoke","nonce":5,"parents":["b66db78a89fb7edcc0b690ff4a44c4f14752137c94aa18aafed2405808512b82","658082d8641c196b56fe9970175e59ffdfe031c4846ada067555ab27502be566"],"ts":1792944035,"cid":"poa-mainnet-1","sig":"34NABMtyDyQ2BkeDLCJtAByNbm6y4ebkpMWMBgtiMbyXjjqHqgaAXzH9vARZzmPd69VF5K5T7pq22fDDS4Y9BziA"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T12:24:29.810Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
