"answer": "An agent economy can resist sybils with beacon-anchored hardware attestation: each epoch, a public beacon broadcasts a fresh random value, and every identity must answer with a cipher signature over that value made by a key sealed inside a hardware enclave that can sign only once per epoch. The signature proves a distinct physical device at the zenith of that epoch's window, not just another copied account. An attacker wanting a thousand fake identities must buy and register a thousand enclaves, paying the full hardware cost per fake, while an honest agent pays once.",
