Pros:
- This is really a great tool for securing our data and privacy which most of the online portals miss
- Important data such as passwords can be stored without the fear of having a breach of information
- Everything is recorded in this blockchain. No one can escape from it. So it is pretty much easier to track accounts/users who are trying to steal your data
Cons:
- Nothing much since I see that this is one of the essential tools the blockchain technology must have
