But my preferred form would be an on-chain reward. A tx which uses its first input's txid to generate the puzzle NUMS, so you can't just copy it. Not sure how to generate such a challenge, maybe GSR, OP_TX plus cleverness... This would start a month-long (4032 block) countdown to disabling vulnerable spend paths, as a final shot across the bow.
