I dont think most of the industries needs Blockchain technology, its not really that important as some people would always be hyping it to be, so its not needed in most places. I think where the blockchain technology can be needed is when it comes to any industry that has to do with tech, just like Microsoft, Apple, Google and others like them. But if you check you will see that these companies dont even make use of blockchain, except that Microsoft Xbox is accepting Bitcoin for their stores.
