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?
In general, the blockchain technology can do without cryptocurrency. I know projects in which there are smart contracts in which cryptocurrencies are not used. It all depends on the business model. But, as a rule, the business model of blockchain projects is constructed using cryptocurrency. It is very convenient. Without this, most projects would not be able to monetize their ideas.
