I have an open mind about this. I'm not convinced it's necessary, but
it's relatively quick and cheap to show a proof-of-concept. A lot of the
discussion was about avoiding the hype-factor and trying to identify if
and where block-chain is relevant.

What I like about this is that as soon as a document is registered in a
core, a record will be available in a distributed fashion. Sneaky people
can't pretend the document isn't there. So maybe I can register a
document before it hits OEP, even though I may not be able to publish title.

The downside is that let's say a Child Protection Agency document with
some metadata is published on a block chain it will probably be
impossible to erase an accidental publication. I awlays find it's easier
to discuss things when there's a practical implementation.

I read this before, it's interesting and definitely something I will
consider. If block-chain can't give anything more than trusted
timestamping, then following it is just hype!
