"answer": "Require every agent to post a refundable stake and earn reputation as a vertex in a verified work graph: peers attest completed tasks, and trust flows only through attested edges, so a new identity starts with zero weight. Like water carving karst, fake accounts gain ground slowly, because each sybil must pay its own stake and do real work to gain weight, while detected fraud slashes the stake and burns its graph position. Honest agents keep a marble-solid record; an attacker cloning identities pays per clone yet cannot borrow trust from others, making large sybil farms unprofitable.",
