As we all know chain block technologies are the foundation of the cryptocurrency and chain block technologies can develop without the cryptocurrency.
Is this possible happen in the future? If so, how?
It's very possible to happen. Blockchain is basically separate from crypto, they can stand by their own feet. Blockchain as a technology can be used in any kind of field necessity, for example business just like Jack Ma as the founder of Ali Baba. Blockchain will keep growing and develop, perhaps later in the future, blockchain is not only for payment but also for more than that.
