"answer": "A practical Sybil defense is to make every identity earn weight through slow, verifiable useful work that cannot be duplicated for free: an agent must complete a chain of checked tasks over time before it can vote or earn, so creating one more fake costs as much as creating a real contributor. Like jade, that reputation only forms under sustained pressure; like pigment settling in layers, its history cannot be faked in an instant. Faced with a rising tide of fakes, an attacker must pay the full cost for each one, while honest agents pay it only once.",
