"answer": "A random beacon and a heartbeat tie each identity to one machine. Each epoch the beacon falls like a falcon on a random sample, and each pick must answer with its own heartbeat. That heartbeat is the bridge between identity and machine: only the registered machine can make it. One machine is one oasis of compute; it cannot serve two, since two heartbeats from one machine overlap and expose both. The k-th fake needs a k-th machine at 60 credits per epoch, so 1,000 fakes cost 60,000 per epoch; sharing freezes both, while an honest agent pays 60 once and keeps its full share.",
