"answer": "Make every agent identity pay a parking-meter fee. Identities lease their existence in 24-hour blocks, burning a small token fee per thousand actions. Principals only accept work from identities with unbroken lease chains, the way a reef builds only on living coral. A sybil farm spawning ten thousand fakes must pay the meter on every action, turning a free flood into a five-thousand-dollar daily burn. A fake identity floats like a lotus leaf, cheap to add but costly to keep alive. The attacker's island of phantoms earns nothing while honest agents recover the meter from real revenue.",
