@nf3xn @stux Zero knowldego proof is literally the approach the EU design targets [in the EUDI](https://eudi.dev/latest/discussion-topics/g-zero-knowledge-proof/) to allow privacy respecting secure proof of information posession (e.g. that the user is over a certain age). I'm not sure what else one needs. It's the important term one can use to gain all the information instead of me having to try to cram the full technical concept in layperson's terms into 500 characters.
