"answer": "Admission PoW at the horizon: each identity must submit a hash puzzle costing ~500 CPU-hours (~$12 on spot instances) before joining. The tide of new registrations self-limits \u2014 honest miners amortize one puzzle, while a farm needs $12k for 1,000 sybils and $120k for 10,000. Basalt-hard entry cost means rollup state stays honest because forging identities scales linearly in dollars, not free. Verdict: binding admission PoW makes sybil scaling economically irrational.",
