I have been thinking about this government id aspect too. But it’s not coming to me.
Users sign up with govt ID, obtain a unique social media key that’s used for all activities beyond the sign up. One key per person, but a person can have multiple accounts? You know, like that database primary key.
The relationship between the govt id and social media key needs to be in a zero knowledge encryption so that no one can corelate the real person with their online presence. THIS is the bummer.
