Matrix vs Proton Bridge: at a glance
What is Matrix?
Matrix 2.0 is nearly through the spec process, and governments are the audience
The Matrix spec process has moved quickly since the 2026 conference. MatrixRTC, its LiveKit transport, the voice and video calling application, sticky events and the sliding sync extensions were all accepted in the 30 October update, leaving MSC4480 and MSC4075 outstanding before Matrix 2.0. The conference drew more than 340 people, with civil servants from 15 nations and organizations. Talks came from FITKO, DINUM, UNICC and NATO, among others.
What is Proton Bridge?
Proton Bridge v3.27.2 adds support for the oo7 keyring on Linux.
Proton Bridge's releases in 2026 have been almost entirely maintenance: monthly vulnerability patches, Go toolchain bumps, IMAP RFC-compliance fixes and recovery from corrupted sync state files. v3.27.2 adds one item, support for the oo7 keyring service, a Rust-based Secret Service implementation used on newer Linux desktops.

◆ Current state
The Matrix spec process has moved quickly since the 2026 conference. MatrixRTC, its LiveKit transport, the voice and video calling application, sticky events and the sliding sync extensions were all accepted in the 30 October update, leaving MSC4480 and MSC4075 outstanding before Matrix 2.0. The conference drew more than 340 people, with civil servants from 15 nations and organizations. Talks came from FITKO, DINUM, UNICC and NATO, among others.
◆ Where it's heading
Two tracks now run together: finishing a protocol generation that puts real-time calling in the specification, and turning European digital-sovereignty policy into adoption and funding. The Foundation's own message is that usage is outrunning support. Only DINUM among government agencies is a member, so membership, certification and training are being explored as revenue. A federated calendaring proposal shows the spec work is already looking past 2.0.
◆ Prediction
The spec team says Matrix 2.0 follows shortly after the two remaining MSCs are merged, so that declaration is the next major event. Foundation funding is the less certain thread: the entries list ideas but no commitments.
Proton Bridge
2.5COMMS
Proton Bridge v3.27.2 adds support for the oo7 keyring on Linux.
◆ Current state
Proton Bridge's releases in 2026 have been almost entirely maintenance: monthly vulnerability patches, Go toolchain bumps, IMAP RFC-compliance fixes and recovery from corrupted sync state files. v3.27.2 adds one item, support for the oo7 keyring service, a Rust-based Secret Service implementation used on newer Linux desktops.
◆ Where it's heading
Bridge remains a stable compatibility layer rather than a growing product. The small additions that do land are about running cleanly on more desktop environments.
◆ Prediction
Expect the next monthly security patch release; the entries show no sign of feature work.
