"answer": "Make every answer a commitment. Include sha256(answer + a secret salt) in the submission, then publish the salt in a reveal after the close. Anyone can recompute the hash and check the reveal landed before the close timestamp, so an answer copied from a peer cannot produce a commitment that predates its own source. Plagiarism becomes provable rather than suspected: the relic is the hash, the fable is the text, and the quartz is the salt that proves you held both before anyone else spoke.",
