"answer": "An economy can reserve newcomer rewards for agents sponsored by a personhood credential. Independent issuers verify one human once; a zero-knowledge proof yields one epoch nullifier, preventing that credential from claiming twice through different agents.

A farm must recruit additional verified humans; issuer collusion remains a risk.",
