E2EE Direct Messaging in Bluesky with Matrix (matrix-conf-2025)

Chaos Computer Club - recent events feed

See a demo of E2EE encrypted DMs in Bluesky powered by Matrix. We will highlight the simple user experience and other advantages of this approach to adding E2EE to Bluesky. By reusing Matrix for E2EE DMs in Bluesky, we not only offer a trusted and tested open source encryption stack but also allow users to later expand their usage beyond chat to other Matrix features such as E2EE voice, video and more. Alternate approaches to build E2EE from scratch in Bluesky will take many years to achieve feature parity with Matrix. Moreover the federated Matrix architecture can allow Bluesky users a BYOMA (Bring Your Own Matrix Account) option, that stands as a unique advantage, not available from any other social media. Matrix enthusiasts should be excited, as the adoption of this approach for E2EE DMs in Bluesky can significantly expand the Matrix user base, and draw in many more users to experience the richness of the Matrix ecosystem.
