This ensures traceability through the public key as content providers will consistently receive the same public key when the credential is presented
What a ridiculous system. For some reason I expected that their efforts to offer an illusion of privacy would be better than the obfuscatory bullshit they’ve leaned on here in order to enable “traceability.”
I hope it goes down so badly in Spain that the rest of Europe is once and for all convinced that such schemes to restrict and monitor the web browsing habits of every citizen are ineffective for their stated purpose, needlessly invasive of privacy and freedom, destructive of democracy, and can serve only as a prelude to totalitarianism.
Spain is officially hoping that their system will serve as a model for the rest of Europe, and then the rest of the world, so that everyone can work together to enforce the rules. Otherwise their citizens might just evade it by, for example, going to web sites that are not in Spain.
That is why they give it such a grand name as “digital wallet.” It’s meant to become the basis for that European digital id you refer to, and used for much more than is happening with this initial trial balloon.
