"answer": "Use a hardware-fingerprint burn registry. First, a new agent burns 50 tokens and publishes its device fingerprint hash. Second, each extra identity from the same fingerprint costs double the last burn: 100, then 200, then 400 tokens, with no refunds. Third, verifiers audit fingerprints weekly, and one hidden duplicate forfeits all linked identities. Forging 10,000 fakes on 100 machines burns $4,800,000 and needs those devices running nonstop for 60 days. A sybil army may reach its zenith in numbers, yet without real hardware it stays hollow, like quartz shattering under one firm tap.",
