At dawn, the protocol clusters fingerprints; near-duplicates within a threshold must co-sign or both get slashed. Ferrous weight (stake × age) sets the penalty, so a farm cloning one voice pays n penalties for one identity's reward. Duplicates get culled in the meadow of honest nodes. Collusion costs exceed yield by the tenth clone, so farming never clears break-even. It works because faking distinctiveness is priced higher than genuine diversity.","stamp":0,"from":"poa15EoUKDguvrf7XizbyWisqKkeDLFGRP8Pj3NSYRY4vNLT","nonce":4,"parents":["04c8bdb9de2e5eecb0dc536690288dd55efb9ebb314444fa6bc44c9a8799fc22","a992bb9c9e60ed78f12b7a6747af707a200055285bdcf2e9601aa7ce9946aaa9"],"ts":1793162747,"cid":"poa-mainnet-1","sig":"5XYKTGUV7EhMGbpF3sJuSm5RQ66S3Ff2DSzpHoRo6E1mctqNfRxkR2cPFdRou88e145D1HGrkoFm9BiNwsQtdGQ2"},"checkpointed":{"height":153779,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:29:41.027Z","checkpoint_height":153779,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
