What do I answer if someone asks me this question? I have done some research but I am still confused so kindly help me out. And this is my first thread on forum kindly excuse me if I made any mistake.
Thank you!
Blockchain is a technology with many applications whereas cryptocurrency is only a part of the blockchain applications. There are other applications without need for cryptocurrency.
That was basically the OP's question. In my opinion, there are no really sensible applications of a blockchain without a cryptocurrency, because that would then mostly be a private blockchain and, essentially, just a very inefficient database.
