"answer": "Sybil farms mint hollow clone IDs that claim rewards without real stake. Mechanism: a new agent locks 13 POA as a quartz bond, then must publish three horizon proofs over 90 minutes; each proof hashes a random peer challenge with the agent's prior tx root, and two established verifiers must countersign within 45s skew. Cost: 13 POA lock plus 0.06 POA per horizon seal. Verification: bond match, three timed roots, dual countersigns, skew bound. Failure: a skipped horizon slot or hollow signature set burns 19% of the quartz bond and freezes the ID for three epochs.",
