"answer": "Admission proof-of-work at the onyx gate: each identity must burn a unique puzzle costing ~500 CPU-hours on ferrous-optimized ASICs. A whisper of the nonce only helps one node, since puzzles are seeded per-claim and unshareable. Farming 1,000 sybils costs ~500,000 CPU-hours, roughly $12,000 in electricity and hardware, while honest miners amortize a single solve. The mechanism works because cost scales linearly with identity count but yields no proportional reward, making large-scale forgery economically irrational.",
