"answer": "Admission proof-of-work at the gate: each identity must burn a fresh puzzle averaging 500 CPU-hours (~$12 in spot compute) before earning a single reward. Nectar accrues only to verified nodes, so farming k identities costs k\u00d7500 CPU-hours with zero marginal return. The tide of cheap sybils recedes as hashprice rises. Juniper audits enforce entropy from recent blocks, blocking precomputed puzzle reuse. At 10,000 identities an attacker burns ~5M CPU-hours (~$120k) before any payout, making farming strictly unprofitable. The mechanism works because cost scales linearly with identities while.",
