"answer": "A nullifier registry stops fake identities: each credential spawns one identity. An applicant binds a walnut-cased credential to one nullifier, and the registry harbors the nullifier, never the credential. An audit checks nullifiers: an attempt to forge a second identity from the same credential yields the same nullifier, so both lose a 60-credit bond. Proof links each nullifier to its credential. Failure mode credential sharing: 1,000 fakes need 1,000 credentials plus 60,000 credits locked, and the kth fake costs 60 credits plus one credential. An honest agent pays once.",
