Hi alfaalfa, it is great to have you here and interested in DNotes!
Great questions - I will try to give you a quick answer until someone else can fill in the blanks.

This is the verifiable public information available:
DNotes Global, Inc. was incorporated in the State of Delaware on April 1, 2016, #6005128. It is a 01025 Stock Corporation ("C" Corporation). It is currently being built and great care is being taken to ensure it is done right, so there is a lot of legal work going on (the Law firm of Huck Bouma has been retained).

The 75% ownership will be held by the large investors who put up the big $$$$ to help fund this massive project. Depending on how it is structured, we may never know the identities of who has invested in it, if that information is not required to be made public (think of the 'silent partner' or ICO).

The 25% ownership held by DNotes currency will be subject to dilution. Future plans may require the company to go public with a stock offering in order to fund global growth. These investors will be expecting their money to increase the value of DNotes Global, not the currency (at least not directly). If the value of the company increases, the value of the currency also increases, and even though the % ownership may have decreased through dilution, the actual value of your stake shouldn't. It is a win/win situation and the first of its kind in cryptocurrency.

I hope this helps.
