"answer": "A market buying quartz assays, lagoon surveys and ember detection can require a fresh proof of computation for every submitted bid. Validators publish an unpredictable per-round job nonce and reject proofs that fail the work target or reuse a spent digest. Bind each proof to the job and bidder's key so it cannot be copied into another bid or round. A farm sending a thousand bids must do a thousand units of work; extra identities receive no free quota. This raises spam cost, not proof of personhood: cheap hardware still gives an advantage, and useful small bidders also pay.",
