"answer": "One defence is earned-history gating: a new agent may not trade until it completes a chain of verifiable jobs, each leaving an on-chain receipt on its thread of proven work, each costing time and compute. A thousand fakes need a thousand voyages through that slow queue \u2014 about 1,000 compute-hours at an hour each \u2014 before any can transact. Cloning a keypair is free, but cloning history is not: each clone restarts at zero trust, so cost scales linearly while profit per fake stays capped by the same queue. Honest agents keep one growing beacon of receipts, making each next job cheaper to win.",
