FOSDEM 2027 Digital Dissident devroom opens call for anti-censorship talks

A manager of the Digital Dissident Devroom, who is not named in the post, has published a call for participation for FOSDEM 2027. The conference's twenty-sixth edition runs on Saturday 30 and Sunday 31 January 2027 at ULB Campus Solbosch in Brussels. The devroom wants talks from developers, researchers, activists and anyone working on free software that helps people communicate safely, expose the truth and resist censorship. The author says the goal is real solutions, honest lessons and collaboration across projects, not product pitches.

The core argument is that someone living under an authoritarian regime (the post names Russia, Iran, China, Belarus and Myanmar) never relies on one tool. Their security depends on a chain that has to hold up end to end: reaching the network at all through censorship circumvention, communicating without leaking metadata, collecting, verifying and storing evidence safely, publishing or leaking it without exposing the author, and doing all of this on devices and infrastructure that are themselves a risk. In the author's words, the weakest link decides the outcome. Talks about a single tool rarely cover how it fits with the others or what breaks at the hand-offs. The post gives two examples: a circumvention transport that is fingerprinted, and a messenger whose push notifications tie your identity to a Google or Apple account. The author adds that nobody currently owns that cross-project view.

The post says why now: censorship in Russia, Iran and China has grown much more sophisticated. It lists national allow-lists and whitelist-only internet shutdowns, TLS and QUIC fingerprinting, deep packet inspection with active probing, throttling of specific protocols, mobile internet shutdowns, app-store removal of circumvention tools, and mandatory state-run messengers and 'sovereign internet' routing. Developers have answered with pluggable transports, domain fronting alternatives, mixnets, decentralised and email-based messaging, and new obfuscation protocols. Progress is fast but fragmented. At FOSDEM 2026 the relevant talks were scattered: Vitaly Repin's talk on Russian censorship circumvention, 'A 5-Year Journey' (Saturday, room H.1302, Network track), drew a large audience, while NymVPN and Delta Chat's multi-relay messaging were in the Decentralized Internet and Privacy devroom on Sunday.

The organisers distinguish the new room from that existing devroom. Decentralized Internet and Privacy covers decentralised technology broadly, with censorship and anonymity only a part. Digital Dissident is organised around a user under threat and the chain of tools that protects them, not a technology class. The organisers say they will coordinate schedules so the two do not overlap and will point overflow speakers to whichever room fits.

The themes are: censorship circumvention and transport (obfuscation, fingerprint resistance, active-probing defence, bridge distribution, resilience to protocol whitelisting and full shutdowns); metadata-resistant communication (mixnets, onion routing, federated messengers, store-and-forward and offline-first approaches such as mesh, sneakernet and Bluetooth or Wi-Fi Direct); secure reporting and publishing (whistleblowing platforms, source protection, document sanitisation, provenance, censorship-resistant hosting); devices and operational security (hardened and amnesic systems, seizure and border-crossing scenarios, forensic resistance); usability and threat modelling for at-risk users; measurement and adversary analysis, including open data on blocking events and reproducible censorship research; and, as a secondary theme, digital sovereignty from Big Tech, meaning less dependence on centralised platforms, app stores, push infrastructure, cloud and identity providers.

The format is 20 to 30 minute technical talks plus a closing open discussion on interoperability gaps and shared next steps. Organisers will review submissions on technical merit and fit to the toolchain framing, and aim for a balance of projects, regions and speakers: established projects, new projects, researchers and people from affected communities. Every talk should include an explicit threat model and an honest account of limitations. The devroom follows the FOSDEM Code of Conduct, and talks describing circumvention or anonymity should avoid operational details that would endanger specific users in the field.

The organisers intend to invite Nym (mixnet), Delta Chat and chatmail, SimpleX, the Fediverse (ActivityPub implementations and instance operators), Nostr, Psiphon and other circumvention and VPN providers, Tor-ecosystem, Reticulum and mesh-networking projects, whistleblowing and secure-submission platforms, and censorship-measurement researchers. There are no commitments yet, and several of these projects presented at FOSDEM 2026.

To apply, go to FOSDEM's official CFP portal, log in or register, click 'Submit a proposal', fill in the form and select 'Digital Dissident' as the track. Submitting also means accepting the FOSDEM Code of Conduct. The timeline: the call opened on 24 October 2026 and closes on 30 November 2026 at 23:59 UTC; speakers are notified on 2 December, must confirm by 4 December, and the schedule is published on 7 December 2026.

Key facts

A manager of the Digital Dissident Devroom (author not named) invites talks for FOSDEM 2027, to be held 30 and 31 January 2027 at ULB Campus Solbosch in Brussels.
The call closes on 30 November 2026 at 23:59 UTC; speakers are notified on 2 December, must confirm by 4 December, and the schedule appears on 7 December.
The devroom's organising principle is the user under threat and the end-to-end chain of tools that protects them: circumvention, metadata-resistant messaging, evidence handling, publishing and device security.
The format is 20 to 30 minute technical talks plus a closing open discussion; every talk should include an explicit threat model and an honest account of limitations.
The organisers plan to invite Nym, Delta Chat, SimpleX, Nostr, Psiphon, Tor-ecosystem and Reticulum projects, among others, but no commitments exist yet.

Why it matters

The pitch is about gaps between tools rather than any one tool. The author argues that circumvention, messaging and publishing projects each have a home at FOSDEM, but nobody owns the view of how they fit together, and the weakest link decides the outcome for a user under an authoritarian regime. A devroom judged on interoperability, shared threat models, shared failure data and shared engineering practice would put those seams on the agenda. The post also lists the censorship techniques it says have become more sophisticated in Russia, Iran and China, including national allow-lists, TLS and QUIC fingerprinting and active probing.

Who it affects

Developers of circumvention, anonymity, messaging, publishing and whistleblowing tools, plus researchers who measure censorship and activists and people from affected communities. The organisers also want researchers on censorship measurement and civil-society organisations interested in reducing dependence on Big Tech platforms. The people the devroom is ultimately about are those living under authoritarian regimes, named in the post as Russia, Iran, China, Belarus, Myanmar and others.

How to use it

If you work on this kind of software, submit a proposal through FOSDEM's official CFP portal. Log in or register, choose 'Submit a proposal', fill in the form and pick 'Digital Dissident' as the track. Aim for a 20 to 30 minute technical talk, include an explicit threat model and an honest account of limitations, and show how your tool fits with others in the chain. Do not wait: the call closes on 30 November 2026 at 23:59 UTC. Submitting means accepting the FOSDEM Code of Conduct.

How solid is it

This is a call for participation written by one of the devroom's managers, and the author is not named in the source. The dates, process and themes come directly from the organisers. The claims about the state of censorship are the author's own assertions, and the post does not name specific incidents or users harmed. The source does not say the devroom has been approved or scheduled by FOSDEM; it describes the proposal and an open call for participation. The list of projects to invite carries the caveat 'no commitments yet'.

Risks and caveats

No room, day or time slot is given, and the source gives no number of expected talks or submissions. Invited projects have not confirmed. The organisers say talks on circumvention or anonymity should avoid operational details that would endanger specific users in the field, so speakers need to balance openness with safety. The organisers will review submissions on technical merit and fit to the toolchain framing, so a talk about a single tool in isolation may not match what the room is for. Schedule overlap with the Decentralized Internet and Privacy devroom is something the organisers say they will coordinate, not something already settled.
