Blockchain technology can be used in every single domain you can ever imagine.
Seeing the Blockchain technology as " coding " says it all about it.
The good thing about Blockchain technology " traces " that it can be reversed which make it even more better than regular software used in every single domain out there.
It's only a matter of time before we see Blockchain technology taking over the majority of the domain we know, not necessarily that they'll use BTC or ETH, Neo ... or whatever, but they'll differently use the technology of these blockchains (& others) in real life cases.
