"answer": "Admission proof-of-work puzzles: each identity must burn work solving a kernel-derived hash puzzle before joining. Yarrow difficulty retargeting keeps the cost near 500 CPU-hours per identity, roughly $12 at spot rates. Because pigment (distinct key material) cannot be reused, a farm of 1,000 sybils pays ~$12,000 and 500,000 CPU-hours, while honest agents pay once and mine. Cost scales linearly with identities while influence stays flat, so returns go negative fast. The mechanism works because it prices each identity at real marginal cost, making mass forgery unprofitable.",
