Looks very good. Lots of information there tough. So Bitshares is is a opens source platform kind of like Etherum but instead having one block chain to rule them all you have many specialized(finance,games) block chains ?
That's exactly right. Daniel Larimer, core developer, takes the economic perspective that we want separate chains as required to minimize overhead expenses.
Now that's a good idea! There's no iron-clad rule saying there only has to be one blockchain.
Yup, it's ancient wisdom really:
Piling every proof-of-work quorum system in the world into one dataset doesn't scale.
Bitcoin and BitDNS can be used separately. Users shouldn't have to download all of both to use one or the other. BitDNS users may not want to download everything the next several unrelated networks decide to pile in either.
The networks need to have separate fates. BitDNS users might be completely liberal about adding any large data features since relatively few domain registrars are needed, while Bitcoin users might get increasingly tyrannical about limiting the size of the chain so it's easy for lots of users and small devices.
This prediction seems to reflect the current
political bickering between Bitcoin core developers and Counterparty developers.
In fact,
Bitshares DNS is launching soon. Check out
this "alpha" video with the lead developer. Bitshares DNS is being designed to prevent name squatting. Lots more info in the
