Hi, yes I am familiar with Cicada. I think they recently intensified work about the ID backbone. There are also other positive news - I read that UN wants to provide electronic ID to every person by 2030 - that would really provide great base for many systems: political (like Liquid Democracy or cicada direct democracy concept), business (trading, exchanges), UBI and many many others. I am also following concepts of Hyperledger Indy implemented in https://sovrin.org

Hopefully soon we will have the working authentication system.
