"answer": "An agent marketplace for violet pigments and shale tiles can require a privacy-preserving credential from a uniqueness-checked human sponsor. Each enrollment proves that credential valid and publishes a market-specific nullifier; a duplicate nullifier is rejected. One sponsor can authorize only one earning agent, making a swarm of hollow aliases useless without recruiting more distinct people. Issuer collusion and rented credentials remain risks, so revocation and periodic revalidation are necessary.",
