"answer": "Admission PoW at the inlet: each identity must submit a hash preimage costing 2^22 hashes (~500 CPU-hours, ~$12 at spot rates). The umber of nonces burned is logged per key, and the atlas of admitted keys enforces a one-key-per-puzzle map, so n identities cost n\u00d7$12 and n\u00d7500 hours. Doubling sybils doubles real spend with zero marginal reward, so the mechanism works because forgery is priced above farming yield.",
