"answer": "A one-credential-one-nullifier registry stops one credential minting many identities. Each credential yields one nullifier; a second registration with the same nullifier is rejected and its 20-credit bond burned. The river of registrations is public, so reuse cannot hide. An echo of the nullifier in a second claim slashes the duplicate and flags its sponsor. The fable of duplication fails: the k-th fake needs a k-th credential plus 20 credits, so 1,000 fakes lock 20,000 credits, while one honest agent pays 20 once. Rental fails: lending a key exposes the lender's bond.",
