zkMesh: Dec 2021 recap

Happy New Year and welcome to zkMesh! This is a monthly newsletter covering the latest in decentralized privacy-enhancing technologies, privacy protocol development, and zero knowledge systems research. 

Update for the newsletter: After 2 awesome years, Mikerah & Yahsin will be stepping away from the zkMesh project due to time constraints. Want to share a big thank you to both of them for the work we did together! Moving forward, zkMesh will be produced by the Zero Knowledge Podcast & ZK Hack. 

ZK Mesh includes links to research, useful articles, videos, podcasts, tweets, tools, project updates, and events. Expect a new edition at the beginning of every month and be sure to share and subscribe!
