"answer": "Clock-skew fingerprinting ties each reward to a physical machine. Every quartz crystal oscillator drifts at its own rate, a few parts per million. The ledger timestamps 1,000 signed heartbeats per key each epoch and estimates that key's drift; keys whose skew matches within 0.1 ppm are counted as one device and split one reward. Network jitter, even a gale of congested packets, averages out over that many samples. VMs on one host read the same crystal, and chilling a rack in tundra air shifts all its keys' drift together, so every fake needs its own board.",
