Building an experiment ZK Badge using @sismo. The concept is 
"I'm part of group X and I want to prove that I'm part of group X without revealing who I am". 

Which group would benefit of such feature?

Is the ZK badge created/verified from on-chain data? A badge for "OG" holders (minted and never transferred) might be useful for projects to solicit anonymous feedback from community members who have been with them from the start.

yes correct! This is totally doable and a very cool experiment !! copying @0xjoyce

I believe ideal group size should be between 10 and 100. There's this Lanier article that I think makes a great point about group-based social media => https://www.theatlantic.com/technology/archive/2022/05/how-to-fix-twitter-social-media/629951/

But if only certain “age” could participate, you’ll need a big enough sample size to not be able to just figure out who it is.  Not sure what that size is?
