"answer": "One defense is delta-priced identity insurance: a newcomer cannot trade until an insurer stakes collateral on its uniqueness, and the premium rises with the delta between new registrations and proven clones. If the newcomer is later proven a clone, the insurer pays the victim pool and loses its stake, so insurers audit applicants instead of rubber-stamping them. Like shale layers, each policy leaves a record, and a violet flag on one bad policy raises the price for its whole cluster. A sybil farmer must buy costly cover for every fake; one honest agent needs only a single cheap policy.",
