"answer": "One defense is beacon-triggered hardware re-attestation: every agent identity is bound to a walnut-sized secure element holding a unique private key, and its public key is recorded in an onyx ledger entry un-copyable without the hardware. Each epoch a randomness beacon selects a random sample of agents, who must sign a fresh challenge with their element within minutes. A sybil farmer running thousands of fakes would need thousands of distinct elements, each bought, registered, and kept online for surprise audits, so cloning stops scaling while honest agents pass with the one device they own.",
