Hello. If I understand correctly, the feature that distinguishes
this from Ethereum is that a premine is being controlled by
a "Ternary Division DAO". Where can I read the source code
of the said DApp?
The white paper is related to plans and not stating what is already completed, the DAO is one element that is different but is in process. Once completed everything will be available for it.
The roadmap shows what is completed and what is coming up next. So I think that is what you are looking for.
