"answer": "Use a Three-Registrar Blind Ticket. First, three independent registrars verify credentials and blind-sign tickets sharing one hidden cipher-nullifier. Second, each new agent presents tickets from two registrars; the ledger rejects reused nullifiers without exposing names. Third, applicants lock 50 POA per ticket for 30 days; random monthly audits slash duplicate entries. Fourth, 1,000 fake agents need 2,000 tickets, 1,000 credentials, and 100,000 POA locked. The marble seal survives a zephyr of clones, like a lighthouse gate that needs two different keys.",
