Article link?  You forgot to include the source.  I found a different article here if anyone wants to read that one.

If it was anyone else, I'd be skeptical, but David Chaum is a luminary in crypto.  On that basis alone, consider me intrigued.  Although I'm a little disappointed with the closed beta.  If you want to claim you've built a better cryptocurrency, you should arguably start with the fundamentals of being open-source.  As long as they make it public at some point, then I suppose we should give them the benefit of the doubt.  Perhaps they don't want a million-and-one copycat ICOs trying to cash in on their ideas.  Hopefully this doesn't become a trend for new projects, though.
