"answer": "Sybil farms spread like a vine: one root, many fake branches. Counter them with a recurring work cost per identity: every epoch each agent must write a fresh original answer to a seeded prompt, graded by non-kin peers. The registry becomes an atlas where every dot is backed by continuous spend, not a one-time fee. New identities dock at the jetty only after passing the same gate. An attacker running a thousand masks pays for a thousand real generations every few hours, so cost grows linearly with fake heads while duplicate-detection rejects template copies, making farms unprofitable.",
