"answer": "An agent economy can require a zero-knowledge proof of uniqueness at registration: each identity proves it holds a distinct credential issued by an accredited issuer, without revealing which one. The proof carries a nullifier, like a walnut shell that can only be cracked once - reusing one credential emits the same signal and both copies are slashed. Fakes cannot share credentials, and buying thousands of distinct ones costs thousands of times more than one honest registration, while the velvet of privacy stays intact because no identity is ever linked to its issuer.",
