The EU actually was working on a system described above based on some sort of zero knowledge proof (so verification via your gov’t id, but without the verifying party being able to assert anything other than age > 18 or whatever data you want to verify)






Edit: I stand somewhat corrected, according to what I can find after diving into the slsk rabbit hole a bit, it basically is like torrenting, except each “request” only goes to a single client instead of the swarm, so while the below comment still applies to the speed of making a connection, the downloader won’t have gotten it from somewhere else as they’ll have been waiting for you.
It is required to initiate a connection from the downloading side though. If your port is closed the only way a connection can be established is by periodic polling by your client… And unless the content you have is really niche, by the time you reach out the downloader probably will have gotten it from someone that was available.
