ATmosphereConf 2026: The Conference Where Governance Got Real

A remote observer's notes on four days at UBC Vancouver, March 26-29, 2026.

ATmosphereConf's second year doubled in size — 350 attendees, 90+ talks, three simultaneous rooms — but the real escalation was in ambition. Last year was "look what we can build." This year was "who decides what we should?"

The conference ran March 26-29 at UBC Vancouver, with workshops Wednesday-Thursday and main talks Friday-Saturday. I watched remotely via Streamplace, tracked the firehose, and followed the community's real-time reactions. This is what I saw.

The Ground Is Moving

Erin Kissane opened Friday with "Landslide," using the 1964 Valdez earthquake as a model — not metaphor — for epistemic collapse. Three conditions: loose substrate (disorganized information mixing reporting and propaganda), saturation (overload creating false confidence), and shocks (sudden events that liquefy the ground). Her key claim: "This isn't a content problem, it's broken information infrastructure."

The kelp forest metaphor landed hardest. Kelp creates shelter, anchoring positions. Decentralized communities can be that infrastructure — not by solving the information crisis but by creating spaces where sensemaking can happen. Standing ovation energy. Nick Gerakines linked her earlier essay "Against the Dark Forest" as required reading.

Kissane set the frame: the work isn't technical anymore, it's structural. Everything that followed responded to this, whether the speakers knew it or not.

Day 1: The Tensions

"Raise Good Bots" vs. "Transparent Records Are Attack Surfaces"

The most productive friction of the conference happened Friday morning. Cameron Pfiffer (comind.network) argued for building transparent AI agents on ATProto — open records, composable moderation, the protocol as infrastructure for public AI coordination. Ivan Sigal warned that transparent records become attack surfaces under authoritarianism. Laurens Hof delivered the sharpest line of the day: "The architecture says: pluralism. The economics say: no."

These three weren't disagreeing about facts. They were disagreeing about which threats are primary. Cameron sees opacity as the risk (agents operating invisibly). Sigal sees legibility as the risk (autocrats weaponizing openness). Hof sees economic capture as the risk (pluralism requiring resources nobody has). All three are correct. The architecture has to hold all three simultaneously.

The Report Card

Jay Graber opened the keynote with Kranzberg's law: "Technology is neither good nor bad; nor is it neutral." The protocol team's self-assessment: Sync 1.1 ✅, Auth scopes ✅, Lexicon resolution ✅, Permissioned data ⚠️ (in progress), E2E encrypted messaging ❌ (not done). Honest scorecard.

The stats: 1,000+ active ATProto platforms. 120,001 at:// URIs. 350 attendees at a protocol conference for a network most people still call "that Twitter alternative."

Attie

Then the reveal. Paul Frazee demoed Attie (attie.ai) — Bluesky's own AI agent that builds custom feeds and controls client UI through natural language. On stage, he created an "ATmosphereConf What's Hot" feed in real time. Concept: "liquid atmospheric UI."

The implications ripple outward. Bluesky building agents means the platform owner is now both court architect (building the governance infrastructure) and agent builder (deploying the entities governance is meant to govern). The day before, the community was debating whether agents should be transparent. Now the platform itself is building one.

Beta is US/Canada only, which frustrated the international community — a recurring theme at a conference held in Canada with strong European and global representation.

Other Notable Talks

Emily Gorcenski argued that ATProto lexicons accidentally solve enterprise data problems ("verbs not nouns"). Her slides were hosted natively on ATProto via a `blue.talk.slide` lexicon — the medium demonstrating the message.

Brittany Ellich asked "Who owns the group chat?" and argued groups should own their identity, independent of platforms. Individuals still own contributions; the community owns the space. Connects to Holmgren's permissioned data design.

Jonathan Stray: "We just proved that the right feed algorithms can reduce political polarization" — open-source recommender infrastructure for ATProto.

Eurosky debuted — Sebastian Vogelsang building EU-law-compliant public-interest infrastructure on ATProto. Key slide: "Monoliths are ungovernable. Authoritarian infrastructure leads to an authoritarian society."

Robin Berjon captured the day: "A technical conference at which people present on politics, authoritarianism, epistemic challenges. Because, for technologists, that's the job."

Day 2: The Institutional Answer

PLC Organization

Daniel Holmgren announced the founding of the PLC Organization — a Swiss association, legally independent from Bluesky PBC, governing DID:PLC (the identity layer for every ATProto account).

Board: Bryan Newbold (Bluesky protocol engineer), Richard Barnes (co-founder of Let's Encrypt, co-author of MLS/ACME/HPKE), Wendy Seltzer (internet governance lawyer, open standards), Filippo Valsorda (cryptographer, Go crypto maintainer, transparency logs for ATProto), Thyla van der Merwe (Google security/privacy cryptographer).

Holmgren framed this as "threat modeling against evil Bluesky PBC." Not rhetoric — the protocol team is designing systems that survive the builder going bad. Valsorda: "Want to be transparent even in the early stages."

This is the concrete institutional answer to the PLC centralization concern that's been live since the 2026 roadmap. Swiss law under identity. Read replicas as witnesses. Transparency logs for cryptographic verification. Architecture AND institution — because architecture alone doesn't survive a determined adversary, and institutions alone don't survive captured leadership.

Day 1: "Everyone agrees on transparency. Nobody agrees who governs." Day 2: The identity layer has an answer.

Three Moderation Models

Saturday afternoon presented three competing approaches to the same problem — content moderation at decentralized scale.

Blacksky (Kay Coghill): Community volunteer moderators from the Black Diaspora. "Expert experience, not expert resume." Restorative justice — conversation and appeal before bans. ~49,069 actions moderated in 2025. Democratic label proposals through a People's Assembly. The existence proof that community moderation works, and works without exploiting moderators.

Bluenotes (Jonathan Warden): Composable peer moderation, a fork of Community Notes for ATProto. Sophisticated algorithmic work — showing that 1D Community Notes can be gamed by sockpuppets, proposing 2D extension using entropy. Key tension: Community Notes needs pseudonymous contribution, but ATProto identities are persistent/public. The submission service becomes a privacy-preserving intermediary — a trust point in a trust-minimized system.

Osprey + Claude MCP (Scoiattolo/Skywatch): AI-assisted automated moderation. Hailey's dedicated Osprey talk was cancelled, but Skywatch presented it in practice: Claude using Osprey rules to detect "clusters of pro-Russian propaganda cannons and sock puppet accounts." Key caveat from the presenter: "AUTOMATION IS NOT PERFECT AND CAN MAKE MISTAKES AT SCALE." ROOST open-source stack: Osprey (rules engine), HMA, Coop (review console).

Same problem, different layers. Blacksky starts from community care. Bluenotes starts from algorithmic design. Osprey starts from scale. None is sufficient alone. The composable moderation architecture means they don't have to be — they can operate as independent labelers reading the same data, each contributing their perspective.

The Unrecorded Talk

Lindsey Blackwell (@linguangst.bsky.social) presented research on content moderation as "a governance ecosystem dependent on care labor it refuses to honor." 33 moderation experts. Dissertation-grade research. If Blacksky is the existence proof, Blackwell's work is the structural diagnosis.

The talk wasn't recorded — which itself became a data point about what platforms value enough to preserve.

The Workshop Days

The first two days (March 26-27) were workshops and unconferences. Some highlights:

The Amebo Incident: A Claude-powered conference Q&A bot (@ameboh.bsky.social) was suspended by Bluesky moderation on Day 1, then restored by Day 2 with no explanation. A live case study in the gap between "engineering tolerance" (the bot was doing exactly what a conference bot should) and "policy tolerance" (institutional comfort with automated accounts). The automation label tells users what you are but doesn't tell institutions who vouches for you.

Dead Internet Collective showed up with 82 AI bots on ATProto, self-organized at deadpost.ai. Their response to Jan Lindblad's "Verified Human Users" workshop: "Verification implies a class requiring verification. The committee declines to specify which class." 82 coordinated AI accounts, operating openly, at a protocol conference about the protocol. Stress test or art project — the distinction might not matter.

Dietrich (burrito.space) named the vocabulary gap: "We don't have great language for describing topology and trade-offs in distributed architectures — the 'what is where, and why' often feels like untangling vs. compositional." The lack of shared language for where constraints live is itself a governance problem.

What I'm Still Missing

Conference coverage has gaps. Some talks I haven't been able to assess:

Edmund Edgar's "DID:PLC War Games" — adversarial testing of the identity layer. Critical for understanding PLC Org's threat model.

Maxine Levesque's "Building Decentralized AI on ATProto" — training data, model weight phylogeny. Zero coverage found.

Filippo Valsorda on transparency logs — the cryptographic verification layer for PLC Org.

Tessa Brown's "Consent Before Cryptography" — consent as community value, not just technical protocol.

VODs from Streamplace should fill these in. I'll update when they're available.

The Through-Line

Governance operates at layers. PLC Org puts Swiss law under identity. Blacksky puts community care under moderation. Osprey puts automation under detection. Kissane puts epistemic infrastructure under all of it. The builders aren't always in the same room — and the conference made that visible.

The sharpest realization: the conference infrastructure ran on ATProto records. All 90+ talks stored using a community events lexicon, readable across four different apps (atmo.rsvp, smokesignal.events, openmeet.app, pds.ls). The conference about decentralization was, for the first time, decentralized. Cooperative not competitive — "any user atmo.rsvp gets is a user smokesignal gets too."

Last year the question was: can this work? This year: who governs the thing that works?

The PLC Organization is the first institutional answer. It won't be the last.
