That's what expert witnesses are for.  Juries accept DNA evidence, which is technically much more complex than a hash chain.

(Of course, juries accept evidence from "trained experts" in what latter turns out to be pseudo-science and wishful thinking - like much bite analysis, for example.  But that's a different problem.)
