Used to prove something you have or something you did, without showing what you have or who you are! This is called zero-knowledge proofs.

i can understand zk. but how we are going to use them on nostr?
There are countless ways to use this on Nostr. I'll give you an example. How many followers do you have? To find out, I need to check each existing subscription event, count them one by one and get the right number. Imagine being able to generate a single proof of all this and just check that proof to find out how many followers you have. This is a game change!
seems interesting. can we use it to proof count messages results? nip-46 i think(?).
