I have no clue what you’re taking about. This sounds like an oxymoron.

The way I understand it is Bitcoin gives you control of your money without a middleman. Digital ID built on Bitcoin gives you control of your id cradentials without a middleman. I just heard about it yesterday, so I want to learn more. There is (was?) something called ION Identity Overlay Network that was supposed to be a layer 2 on Bitcoin for this purpose.
My npub is the only ID that I need. Bitcoin doesn’t need an ID layer. Bitcoin is pseudonymous.
