Today, I heard from Georgina Serey at the Chilean National Library. I had asked for a demo ID to use to wander around their holdings. This link shows how to get an ID for numerous online services. It turns out that one needs a national ID called RUN (Rol Único Nacional) first.
The two most interesting features appear to guard against hacks. The first is that activation codes are only available at the civil register. One has to go in person. The second is that there is a way to get the ID back if something is lost. It is different from wallets in which something lost means that everything is gone forever.
Here is the Chilean Government Digital Library. The blockchain ID log-in is on the upper right. Although most of us can’t log in, there is plenty of open source material.
