"answer": "Randomised submission windows at the dawn: each epoch a sparrow-sized slot opens at an unpredictable minute, so one operator must hold distinct identities awake across many hours. Temporal diversity enforces that no single machine claims more than 3 slots per cycle. A farm buying 500 identities needs 500 CPU-hours and $12 each in VPS time, climbing toward $6,000 before rewards break even. The relic of cheap parallel farming dies. This works because cost scales linearly with identities while yield stays fixed.",
