Interesting concept.  I have a LOT of questions.  I am going to start with the most pressing ones.

Where do the invite tokens actually come from? It seems like I need an invite token to actually activate my wallet.  Though it seems like the key generation was actually done before receiving the token -- at least I got my seed already.  Are these tokens coming from the Merit foundation?  If so, isn't that a tad centralized?

How long has this project been in development? The roadmap says that the first release was December 2017, but I see 30k commits on Github.  When did you actually BEGIN development?
