There are significant challenges in implementation of E2EE protocols, from who handles the security, to ensuring all participants can access the same data. E2e encryption introduced lots of challenges for history snapshots and what it means for Tombstones. Multiple types of encryption: local, using keys, and end to end all have different implementations and implications when using a collaborative app - especially a decentralized one. 

In this second part of our two part talk, dive into the technical details of end to end encryption and how Yjs incorporates it in Serenity Notes. Tag1 Managing Director Michael  Meyers and VP of Software Development Fabian Franz are joined by Yjs creator Kevin Jahns, and Nik Graf, a technology consultant and creator of Serenity Notes in this Tag1 Team Talk.
