So I think I get the Mijin-NEM link.
NEM is like bitcoin to Mijin, Mijin is like an alt-coin that depends on the NEM blockchain, correct??
Mijin is a private fork of NEM, kind of the way a lot of altcoins are to bitcoin, but unlike many scam coins, it has a real purpose in the business world as it has been optimized to run on private networks. A Mijin chain and the NEM main chain don't interact in the same way Litecoin and Bitcoin don't interact.
But unlike Litecoin and Bitcoin, both NEM and Mijin share the same awesome set of APIs. So DF running a Mijin chain is now introducing NEM technology to a software platform that services over 5,000 companies, some of them are Sony, Panasonic, and Mitsubishi among others.
Does this mean that Sony will be making transactions on NEM? Not at all. Does it mean that they will even use Mijin as a part of their software suite? No, they might not even chose to turn that part of their software on. There are 0 promises here.
But, what it does mean is that it is possible they
might someday use Mijin as in theory that service can very well be offered to them in the future as a blockchain service built into their software. And once they are doing that and they have started using the Mijin APIs for some private services on Mijin, they are a very small step away from pointing those same APIs at the NEM main chain for different services. That choice will be completely up to them though and if they do, it won't be happening this spring or summer I guess.
