Is End-to-End Encryption Optional For Large Groups? - Dhole Moments

Every Voice and Video Call on Discord Is Now End-to-End Encrypted

As of March 2026, E2EE is now enforced for every voice and video call on Discord. This represents a multi-year commitment, and Discord’s VP of Engineering is here to talk about why it matters.

The Long Tail of Work Left Until ActivityPub Has E2EE - Dhole Moments

Separate from my proposal for key transparency for the Fediverse (which I’ve certainly blogged about a lot), the W3C has been working on building out end-to-end encryption (E2EE) for Activity…

Let’s talk about AI and end-to-end encryption

Recently I came across a fantastic new paper by a group of NYU and Cornell researchers entitled “How to think about end-to-end encryption and AI.” I’m extremely grateful to see th…

Making end-to-end encrypted AI chat feel like logging in

We want private AI chat to be simple. Yet today, many end-to-end encrypted experiences still have a level of friction that make them feel like they’re from another era: it usually either involves a long seed phrase users are asked to “store securely,” insecure password based encryption, or apps that aren’t cross-device and lose your data periodically (on reinstall, browser cache clear, etc).

Key Agreement for Decentralized Secure Group Messaging with Strong Security Guarantees

Secure group messaging protocols, providing end-to-end encryption for group communication, need to handle mobile devices frequently being offline, group members being added or removed, and the possibility of device compromises during long-lived chat sessions. Existing work targets a centralized network model in which all messages are routed through a single server, which is trusted to provide a consistent total order on updates to the group state. In this paper we adapt secure group messaging for decentralized networks that have no central authority. Servers may still optionally be used, but they are trusted less. We define decentralized continuous group key agreement (DCGKA), a new cryptographic primitive encompassing the core of a decentralized secure group messaging protocol; we give a practical construction of a DCGKA protocol and prove its security; and we describe how to construct a full messaging protocol from DCGKA. In the face of device compromise our protocol achieves forward secrecy and post-compromise security. We evaluate the performance of a prototype implementation, and demonstrate that our protocol has practical efficiency.

Integrating Germ with AT Protocol — Germ Network

End-to-end encrypted Germ DM is now a Bluesky messenger. In this technical post, we introduce the architecture of Germ’s integration with AT Protocol. From the beginning, Germ has been building for an interoperable E2EE ecosystem, and this extends to our integration with AT Protocol. We’ll define th
