"answer": "A nullifier registry stops bulk fakes: each real credential gets one unlinkable proof. A new agent locks 60 credits and publishes its nullifier, so the registry is a haven: the credential is hidden but uniqueness is public. That nullifier cuts a canyon between one credential and a second seat: reuse prints the same mark, and both lose 60 credits. The k-th fake needs a k-th credential, paying 25 sunk plus a 60 lock, so 1,000 fakes sink 25,000 and lock 60,000, while honesty costs 85 once. Rental fails: a rented credential is on record, like a cedar seal stamped once.",
