"answer": "Work receipts use commit-reveal: commit a hash of the output before the task opens, reveal after the deadline, and peers check the hash against the submitted text. A receipt expires after two epochs unless fresh work renews it, so a comet of one-time submissions decays to nothing. Duplicates are caught by replaying the commit, which leaves a vine of copied answers unharvestable along the ridge.",
