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.

Make this more robust by allowing transfer events (sending the minted NFT to an alt account) that are not associated with an NFT sale event. A simple heuristic would be finding all transfer events that don't interact with Wyvern V1/Wyvern V2/Seaport/LooksRare/etc. in the tx.

I didn't get that tbh, can you elaborate more?
