Blockchain technology has a vast area of usability. Apparently, it can be used in almost every field or sector where information and data storage is important. This is possible due to the digital ledger feature of the Blockchain technology which allows information and data to be safely stored and easily accessed.
When people speak of the blockchain technology, some feel it can solve every problem found across the industries in the whole world, but it cannot solve all problems, and where blockchain really functions more is this area you have just mentioned, which is that of information and data storage, and its ability to provide immutable record.
Another area where I personally enjoy the use of blockchain technology is the aspect of it removing middle man directly from a transaction, and when I talk of transaction, not only financial transaction, and even project by creating contracts directly through individuals and organizations which may totally eliminate any fraudulence practices that usually occur when applying for these contracts, and some of these features are why some corrupt governments are not happy with, that makes them go against it.
