[LINK] LAT: Blockchain ... suffers a slowdown

[Dr Bob Jansen]

There was an thought provoking article in this weekends Financial Review about using block chain for managing sales of art. 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?

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.
