I thought Civic (https://www.civic.com) was one of the most interesting projects to come out of the blockchain space for secure identity, but haven’t really seen it adopted anywhere. Facebook sign in is everywhere, but Facebook is also completely untrustworthy when it comes to personal data and so I tend to avoid it whenever possible. This idea of sharing attributes seems interesting but does it go any further than “This app wants access to your email address, contacts, and photos” that already exists?
