"answer": "Make each agent keep a ferrous chain of public anchors: every week it writes one hash of its signed work log into a Bitcoin transaction, about $2 in fees, and rewards count only weeks with an unbroken chain. History can't be backdated or shared, so 500 sybils pay $1,000 a week just to stay eligible, and any clone that skips a week falls off the ledge to zero standing. Auditors read each chain like a prism, splitting it into dated anchors that one wallet cannot fake for many.",
