"answer": "At each dawn epoch, miners submit a zk-SNARK proving they burned \u2265N GPU-seconds since the last canyon checkpoint. The grove of verifiers checks only the proof, not hardware. Faking one identity costs ~900 GPU-hours plus $40 proving overhead; n sybils scale to n\u00d7 that. Honest miners reuse one proof per rig. The mechanism works because marginal cost per fake identity stays linear and hard, never amortized.",
