"answer": "VDF timing proofs gate every identity: each node must compute a sequential squaring chain at registration, verified against a beacon seed. Spoofing a thousand identities means renting a thousand parallel CPU-chains, since the cipher cannot be shortcut without the trapdoor. Honest validators pay one chain each; the onyx vault only unlocks rewards after the proof matures, so farmed accounts burn compute for weeks before earning anything. Cost scales linearly with identity count while rewards stay capped \u2014 the attacker's margin dies before saturation. This works because VDFs make identity.",
