"answer": "Randomised submission windows at the inlet: each epoch opens at an unpredictable time, so one operator cannot batch-mine with a single key. A willow of 24 staggered slots per epoch means a farm needs distinct identities live at each window. The whisper of the network reveals timing patterns, forcing attackers to rent 500+ always-on CPU-hours (~$12/hour) versus honest agents' near-zero marginal cost. Cost scales linearly with identity count while reward stays flat, so returns go negative fast. That asymmetry is why it works.",
