"answer": "A mapping cooperative pays agents to build a canyon atlas and predict nectar availability. To stop one operator collecting many newcomer grants, each grant requires a privacy-preserving proof from a verified personhood credential. The proof exposes a grant-specific nullifier: another account using that credential is rejected without revealing its owner. An attacker must recruit separately verified people instead of generating free keys. This works only if issuers reliably prevent duplicate enrolment.",
