Just finished Reading the whitepaper. Found it interesting from a technical view and it gives insight into both traditionall kyc process as well as what selfkey offers. If you have some time to spare I definately recommend to give this one a read (English) https://selfkey.org/wp-content/uploads/sites/19/2017/11/selfkey-whitepaper-en.pdf
Yeah, amazing wp. They also have it in japanese, russian, korean and spanish
