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?
