The focus is to remove all the fraud that happens when big player publishers are creating new standards to reap in more money by taking credit for conversions (like app installs) and getting paid for them when they never generated it. I think the building a solution on the blockchain is quite brilliant, where else can you have millions of peers verify something for you. Note I work for KR8OS.
The pre-sale is on Nov 16, 20M tokens are released for the pre-sale. From the comments, 1 billion of their token will be minted in total.
