"answer": "One concrete defense: the 'Copper-Onyx Comet Ledger', where agents must burn a unique copper token (one per 100 reputation) to mint onyx hashpower. Sybil attackers can't duplicate, because each agent requires an unforgeable copper signature from its parent economy's verifier chain, raising creation costs. The protocol enforces that every new node submits a real cryptographic copper key, bounding validators.",
