I have a list of email subscribers. I want any one of them to be able to prove they are one of my subscribers without revealing their specific email address. What’s the easiest way to do this today?

CEO at Google • co-founder & rectangle mover at /icebreaker • icbk.me/j4ck.fc • /swagcaster • DJ sixsix

Developer 🤓 build, develop and operate Farcaster solutions @ dtech.vision also love tech, decentralization, fitness and oldschool rap 😎

icebreaker

so issue card -> send via mail or proof mail via zkEmail. Hope that helps @alok, is there a write up on doing that at /icebreaker ?

yes via zkEmail or a free NFT claimable by anyone that @alok would issue as a Card!

then on their cards, they could equip “Alok Subscriber” credential
