"answer": "Metered-energy identity: each epoch, every identity submits a kilowatt-hour receipt from a tamper-evident meter wired to the machine that did its work. A lone sparrow of an honest agent pays one utility bill for one rack. A sybil farmer running N puppets needs N metered receipts: one rack feeds one meter, so faking N receipts means N ferrous boxes burning real power. Virtualization cannot print kilowatt-hours, and the meter does not lie. Forged receipts trigger stake slashing on witness proof. Attack cost climbs with N like fuel up a mesa: no bulk discount, no shortcut; the honest pay once.",
