In a groundbreaking move within the realm of social media, the decentralized platform Bluesky has partnered with the startup Germ Network to introduce end-to-end encrypted (E2E) messaging directly within its app. This integration positions Germ DM as the first private messaging service that can be accessed natively on Bluesky.
As part of this launch, Germ is also providing guidance for other applications built on the AT Protocol, the technology that underpins Bluesky, allowing them to implement similar messaging functionalities.
This initiative showcases the unique dynamics of open social networks, where community-driven development can introduce new features, contrasting sharply with the more rigid structures of traditional tech giants.
Earlier this month, Bluesky announced its collaboration with Germ, highlighting that this experimental integration allows Germ users to add a messaging button to their profiles, enabling others to reach out securely within an encrypted environment.
Germ's standalone application is currently in public beta on iOS across North America and Europe. Following the announcement of the integration, the app saw a fivefold increase in daily active users, reflecting the growing interest in secure messaging options.
The startup, based in California, was co-founded by Tessa Brown, a communications expert with a background at Stanford, and Mark Xue, a former privacy engineer at Apple. They aim to provide a viable alternative to existing E2E encrypted platforms like iMessage and WhatsApp, utilizing innovative technologies.
Germ employs Messaging Layer Security (MLS), a newly approved standard by the Internet Engineering Task Force (IETF), along with the AT Protocol, which powers a variety of social applications including Bluesky.
Rather than relying on users' phone numbers, Germ leverages the AT Protocol for its encrypted messaging, ensuring that messages remain inaccessible to any external service, including itself and Bluesky.
To utilize this new messaging feature, users can simply click on a badge on a friend's Bluesky profile, which opens a lightweight iOS App Clip. After authenticating with their AT Protocol handle, they can immediately send messages. Users are also encouraged to download the full Germ DM app, although this is optional.
Those wishing to add the messaging badge to their profiles must download the Germ DM app and authenticate their Bluesky credentials. Initial setup may require restarting the Bluesky app to see the new badge.
Germ has been preparing for this integration for several months, having started with a private beta that utilized "magic links" in user bios. Now, users can display a dedicated badge on their profiles, enhancing visibility and ease of access.
Collaboration with the AT Protocol community, including Bluesky's teams, has been ongoing since last year's ATmosphere Conference. Germ has focused on refining its features based on user feedback, aiming to improve the user experience significantly.
While the AT Protocol may eventually support E2E encryption, current efforts are not centered on this aspect. The complexities involved in implementing such systems are acknowledged by Bluesky's protocol engineers, who emphasize the challenges developers face when working with encrypted data.
Looking ahead, Germ plans to introduce additional messaging features, with potential paid options aimed at professionals such as creators and journalists, focusing on enhancing user experience and functionality.
