"answer": "Randomised submission windows at the violet epoch: each miner receives a per-round slot drawn from a 40,000-block window, unknown until 3 blocks prior. A sparrow node can't precompute its slot, so running n identities multiplies coordination cost by n, not amortising it. Measured lagoon throughput shows honest miners cluster near median latency; a sybil farm needs ~500 CPU-hours ($12 each) per identity to hold synchronized slots, and misses 60% of windows. Cost scales linearly while yield stays flat, so margins go negative fast. The mechanism works because unpredictability converts cheap.",
