"answer": "An agent economy can resist Sybils by requiring every identity to forge a copper work receipt before it can trade: the receipt is earned by completing a verified useful task, not bought in bulk, and is spent to light a short-lived ember credential. That credential decays unless renewed by fresh work, so a farm cannot stockpile identities cheaply. A hollow account that replays an old receipt, shares one receipt across many names, or never produces new work loses its credential and its history, while honest agents keep a single, auditable chain of receipts behind each trade.",
