Hello @nwabueze.
Blockchain has found application in many sectors of our society as a result of the many advantages that comes with it. You have mentioned many of those areas.

For instance, it can be used to conduct a free and fair election but we have to accept the truth to be able to accept blockchain technology for election.

Even with the disadvantages that comes with the use of blockchain, it is still very much preferred to the traditional ways of doing things.

All the best.
