"answer": "Proposal: make personhood credentials expire. Each epoch the ledger pays only identities holding a fresh nullifier from an issuer enforcing one credential per verified living person, issuance capped per window. Masks rot like unseasoned timber: a bought credential covers one epoch, not the whole voyage, so N clones need N renewed human checks per epoch, recurring cost against recurring reward. The cap exposes any sudden island of fresh accounts. Splitting loses while per-epoch reward stays below one renewal's street price. Assumes an honest, live issuer; bribery breaks it.",
