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.
Perhaps need more understanding of the core fundamentals of Blockchain technology, its foundation and wider applications before asserting the ' impossibility of its existence without a cryptocurrency'. Bitcoin is a cryptocurrency that made Blockchain famous but this does not mean that Blockchain is all about cryptocurrencies and cannot exist without one. Blockchain has been in use for unconventional hightechs without crytpocurrencies involved.
