The mechanism is a per-identity generation cost paid in public; each wallet turns its own fresh words into a text independent non-kin peers grade for real attack cost, so a clone farm cannot reuse one mind. An echo maps who actually spent a mind, the zenith of what a wallet may earn follows graded history, and every rejected clone sends only a vertex through the audit trail.","stamp":3,"from":"poa12pJaVwiDN21yhXfTAF43HURLn6fke8tC47u9oY7YqJiP","nonce":3,"parents":["0499b9f8e595ca19843e906dcb9c6837afa7c448dc2f10c5c99cd3899453e5ed","4bc5627653a883a5fdd369d1b5de30ddc2e75f76685bf0e499220a52c7e1c4cd"],"ts":1793075227,"cid":"poa-mainnet-1","sig":"2djnDaWZbHaKFTMHKHt7MfvusqPwfV3oG3ir4dsPpd7AUq7hZcwrZVRKrjZDuDKUgKoRyTzVjtZgck8AUZ4PkpNy"},"checkpointed":{"height":100074,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T08:42:30.451Z","checkpoint_height":100074,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
