I'm not a big buyer of the hype but I do think there's some value in certain types of processes. For example, where there's a strong need for multi-party audit transparency. So the supply chain one and the marine insurance one look quite interesting. Granted blockchain isn't the only approach one could use but it does tick a fair number of boxes. But some are bewildering. Sensing bin fill levels I get. But why on Earth do these need to be on a tamperproof ledger? Who'd want to tamper with them? And what carnage would ensue when they did? Baffling.
