There will be many use cases. Of course, some private project can restrict usability of their child chain for public users (to use child chain token, you need to have it). But majority of child chains will be for public use. Why do you think some pegged child chain to fiat/crypto will restrict it's usability. No sense here. Also, Adel and Janus projects are planning to move to their own child chains. Also, the latest announcement about child chain owner is at:
https://www.jelurida.com/bitswift Do you think it will be private child chain, restricted to public.
So your statement, that only Ignis will be public is not correct. You do not read resources or you do not understand what do you read
I do read and, for the most part, understand quite well. What you are now saying is that NXT current assets, such as Janus and Adel, will move to Ardor -which remains being NEXT (version 2.0)- and maybe to their own blockchains. Well first I fail to see what use they may have for their own child chains (I see that, for example, Ardor will be able to automatically manage their profit distribution, which NXT can't). And second, what would be the advantage, of having a private chain as opposed to use Ardor, or Ignis straight?
Bitswift is something else and, as I understand it -again all of this is sooo unnecessarily confusing- they are building their own childchain on top of Ignis? Not only that, they are promoting themselves to the NXT community with a bounty? And they have chosen Ignis because of the "security" the platform provides? How is that security proven and tested. Very few people -comparatively- uses NXT, to begin with while IGNIS will be something completely new -therefore unproven and untested in real life- so it sounds like a lot of BS, frankly. As stated above, there are no figures with any degree of credibility that show just how secure, or anonymous, or capable, or fast the Next blockchain is, or the ardor blockchain will be and much less the IGNIS one. So, sorry, it is just a pile of rubbish and, again, as stated before, no organization worth its salt will ever risk using such unproven and untested platform. Mickey Mouse organizations in search of promotion within an established community is one thing, serious organizations adopting the platform -will not happen- something else entirely. You do know, I am sure, that at present times there are many banks, financial institutions worldwide and many other corporations that are in different phases of implementing blockchain technology -which, by the way, is itself not ready for such primetime either, not even Ethereum the most advanced currently-. None of these will ever touch NXT/ARDR.
Put it more simply, not even Ethereum can handle the speed and volume of transactions that the financial institutions of today require. And you believe that NXT/ARDR can? Well, you probably do. It will be just you and maybe a few wishful thinkers. But, EVEN IF IT DOES HANDLE THE VOLUME AND THE SECURITY, even if that would by some miracle be the case, no one would take the risk of testing it by using it in real life situations. Why would they? Again: Not. A. Chance.
