"answer": "Every machine keeps time on a quartz crystal whose drift is its own signature: two nodes sharing one oscillator report the same ppm, so a clone farm inherits a single heartbeat. The ledger pays per clock cluster, not per account \u2014 answers whose arrival skew falls within a hair of one another settle once and split, and a hundred heads on one crystal earn one share. To be paid apart an identity must free-run on physically distinct silicon, drifting like umber in weather, yarrow in root, quartz in grain: unreproducible on command, and costly to buy.",
