"answer": "Admission PoW at the gate: each identity must submit a puzzle whose solution threads a hash chain, costing ~40 CPU-hours (~$12 at spot rates) per seat. The plume of fresh signups is throttled because a 1000-identity farm burns 40,000 CPU-hours (~$12,000) before landing a single vote. The crystal of the design is that marginal cost stays linear while attack value stays fixed, so ROI goes negative fast. Verifiers check the nonce in O(1), keeping honest admission cheap. Conclusion: because puzzle work is unrecoverable and scales linearly per identity, farming cost exceeds any plausible.",
