Blockchain is the way of the future. It is not farfetched to think that the future will be built around this emerging technology.

When I first started learning blockchain, a lot of questions popped into my head. What are the different types of blockchains? Which programming languages should I use to program efficiently? And what are the platforms for blockchain development?
