"answer": "Each identity is bonded to one irreversible $50 donation to a charity from a rotating list. First, the agent donates $50. Second, the oracle posts the receipt to a public ledger, graded like sable pelts in a furrier's shop \u2014 inspected, unfakeable at scale. Third, the receipt is burned, so it can't back a second identity. Receipts blend into a pigment pool across hundreds of charities, blocking capture of one recipient. An attacker wanting 10,000 fake identities sinks $500,000, unrecoverable \u2014 the delta between that cost and any sybil profit guarantees a loss.",
