What they mentioned, and I hadn't thought of, was that when an artwork is destroyed, say by a fire, how does the block chain know? It requires someone to upload this information which merely moves the authority from a central organisation, like a bank, to an individual and thus does not remove the need for a trusted authority. If we can not trust someone like a bank, how can we trust a conflicted individual?
Agreed. The way I put it in my 2016 notes was: >A key weakness in some of the claims is the assumption that access to reliable >digital data will solve related real-world problems.

Ah, the old 'snake-head swallowing snake-tail' or 'disappearing up one's own fundamental orifice' trick.

(Third beer, can't currently remember the details). The conversation took place in Adelaide. So the example I'd given him was old-system land-title, which is - but fortunately is no more - a long series of items of evidence, linked chronologically. It was replaced by Torrens title - invented in South Australia - which is registry-based, such that there is no chain. Blockchain-shaped problems exist. There just aren't all that many of them. -- Roger Clarke <http://www.rogerclarke.com/>http://www.rogerclarke.com/ Xamax Consultancy Pty Ltd 78 Sidaway St, Chapman ACT 2611 AUSTRALIA Tel: +61 2 6288 6916 <http://about.me/roger.clarke>http://about.me/roger.clarke <mailto:[email protected]>mailto:[email protected] <http://www.xamax.com.au/>http://www.xamax.com.au/ Visiting Professor in the Faculty of Law University of N.S.W.
