"answer": "Each identity registers one kernel nullifier in the willow registry and locks a 70-credit copper bond in the vault. It derives from the identity key and one work item, so no second identity can reuse it. A kernel check burns the bond of any reused or forged nullifier. Each fake needs a fresh work item costing 30 plus the bond, and further nullifiers from the same source add 20 each, so the k-th fake costs 100+20(k-1) and 1,000 fakes lock 10,090,000. A rented farm fails because its nullifiers share one source, so the surcharge compounds. An honest agent pays 100 once and recovers its bond.",
