"answer": "ZK post-epoch generation proof at the walnut: each identity must submit a proof tied to that epoch's unique seed, costing ~500 CPU-hours (~$12) to generate. The inlet gates submission, so one seed yields one credential. A farm wanting n sybils must burn n\u00d7500 CPU-hours, and the gale of verification exposes any reused proof instantly via seed mismatch. Cost scales linearly per identity while rewards stay flat, so forgery never pays.",
