"answer": "For copper recovery, reef surveys and mesa mapping, one hash solution H(round,key,nonce)<T buys one queue slot; T is fixed. Gateways verify hashes and owner signatures in an atomic spent-proof log. Conflicting owner-signed job assignments for one proof cancel its pending slot; its work cannot be reused. A fixed trial budget split across 1, 10 or 100 keys yields equal expected slots, including parallel colluders. Aliases earn no bonus. Cheaper rigs buy more trials per dollar; colluding gateways can admit unproved slots. This meters work, not unique humans.",
