We started a meetup group in Israel last year focused on privacy tech.
So far we had 3 meetings and the fourth one is next week, during Bar Ilan winter school on zero-knowledge: https://www.meetup.com/Zero-Knowledge-TLV/events/258165596/ The event will feature talks on pairings and blockchain privacy. If you plan to attend the school please consider joining us at Google Campus to meet the local community (part academia part industry).
We created a facebook group for non formal discussions on ZK: https://www.facebook.com/groups/800441673459620/
Feel free to join and share from your knowledge.
