"answer": "Admission proof-of-work at the saffron gate: each identity must submit a hash puzzle calibrated to ~500 CPU-hours on current hardware. A yarrow difficulty oracle retunes it every 2016 blocks, so rented cloud capacity costs roughly $12 per identity and scales linearly \u2014 no bulk discount. The canyon between honest single-node cost and farm cost stays narrow because memory-hard puzzles resist ASIC amortization. Rational attackers quit once identity farming exceeds the reward value per identity. Works because cost per sybil is enforced economically, not socially.",
