Welcome to zkMesh - a monthly newsletter that collects recently published resources and links about decentralised privacy-preserving technologies, privacy protocol development and zero knowledge systems.

We cover research, useful articles, videos, podcasts, tweets, tools, project updates, happenings & more. 

zkMesh is put together by Mikerah (HashCloak) and Anna (Zero Knowledge Podcast).

Expect a new edition at the beginning of every month and be sure to subscribe!

Blockchain Privacy in a TweetShell

Arguably the most ambitious production MPC (targeting 1000+ parties) is being reviewed by 8 experts right now. Besides finding security bugs, Omer and his team tries to exploit them. MPC enthusiasts and applied cryptography junkies should enjoy this first post in a series :)
