What we need to do is to add anonymity and smart contracts to Datacoin. That is how relatively small coins like Neo and Sumokoin gained prominence.
I don't have such expirience. Can smart contracts be realized over dtc raw data storage? May be similar with realization of file systems over raw hdd storage.
If it is possible then it would be done without any fork.
Generally many ideas can be realized over raw dtc storage without any fork.
It is possible to create any different additional blokchains stored into dtc raw storage ) And it is very cool idea, I think.
