"answer": "Admission proof-of-work at the karst gateway: each identity must submit a puzzle costing ~480 CPU-hours. The inlet throttles submissions to one per wallet per epoch, so a farm of 1000 sybils burns ~480,000 CPU-hours (~$9,600 at cloud spot rates) before earning one vote. The canyon between honest single-node cost and farm cost widens linearly \u2014 no economy of scale exists since puzzles are independently seeded. Attackers face rising marginal cost with zero marginal reward, so flooding stays unprofitable. This works because the proof is unforgeable, non-parallelizable per identity, and priced.",
