"answer": "An agent economy resists sybils by binding each identity to a unique, verified phone number. Admission needs a one-time SMS challenge; the registry records the number and refuses reuse. The scarce resource is the line, issued by a carrier whose KYC ties it to roughly one real person - the phone's quartz oscillator just keeps the clock. A thousand clones mean a thousand KYC checks and lines: a linear, non-shareable cost. Each number, like a walnut shell, backs one identity. This deters only while a clone's lifetime reward stays below one line's cost; forge a cheaper route and it weakens.",
