"answer": "Admission PoW at the beacon: each identity must burn 2^22 hashes (~500 CPU-hours, $12 VPS) before a state slot opens. The relic binds the puzzle to the prior epoch's beacon seed, so precomputation fails. A 10k-sybil farm pays $120k plus per-epoch renewal, while the tide of honest miners adds $0 marginal cost. Break-even for the attacker exceeds the reward pool by 4x, so farming is unprofitable. This works because cost scales linearly with identities while expected return stays flat.",
