Listening to the #mainstreaming of the 3 protocol mess, we have a building signal-to-noise issue. We need to push signal, so good to think before you share something that is likely more noise on this subject. As a way out of this, I have been pushing bridges for a while as they are the lowest common denominator and can be built and implemented “permissionless” to allow people to cross #4opens protocols. “Permissionless” is important as the is no way you would get consensus to do this, without...
Protocol Reader - Summer of Protocols
The Protocol Reader The Protocol Reader is an 358-page book (currently only available as an epub) comprising 26 foundational essays by 31 authors from the Summer of Protocols program, carefully edited and sequenced to introduce you to the fascinating new discipline of Protocol Studies. It can serve as

Protocol Reader - Summer of Protocols
In the Fall of 2022, the word protocol was suddenly everywhere. The proximal cause was obvious: fueled, in part, by the highly visible and fractious change of ownership at Twitter, large numbers of people began heading for the exits. Most of them, of course, were just looking for

Dangerous Protocols - Summer of Protocols
Protocols are frequently touted as the liberating alternative to walled technological gardens, but the historical purpose of protocols has always been to simplify decision-making and reduce human agency. How do we reconcile these two narratives? I explore the dangerous side of protocols, and how their ability to drive coordination means they also have

Permissioned data proposal discussion
This is a forum thread to collect feedback on the permissioned data protocol proposal! To clarify: this is still a proposal. I expect many changes along the way. Suggestions may also be submitted as issues/PRs. I had hoped to have an alpha version of the PDS alongside this proposal, however I didn’t quite get there yet. Hoping to have that in the next couple weeks. The previous thread was here: Early permissioned data proposal draft feedback Changes since then: Responded to a bunch of feed...

Why a New Protocol? The History and Future of AT Protocol - AT Protocol
Bluesky CTO Paul Frazee and Head of Protocol Daniel Holmgren join for a wide-ranging conversation about what atproto is, why it exists, how it got built, and where it's going next. From a Twitter consultancy to an IETF working group, this is where to get started.

Decentralization Trade Offs in AT Protocol and ActivityPub DWeb Camp 2026
Christine Lemmer Webber is lead author and co-editor of the W3C ActivityPub specification. Daniel Holmgren is Head of Protocol at Bluesky, working on the AT Protocol specification at the IETF. Join us for a discussion on decentralization trade-offs and other design decisions in the two protocols, and what that means for different architectures, structures, and even future points of convergence. Moderated by Boris Mann
Playing with Parlances - Permissioned Data & AT Protocol - AT-WayFinding
Community privacy is one of our top priorities at @transrights.northsky.social which isn't possible out of the box with any ATproto implementation today that doesn't just hide an entire PDS. We're developing in the open and so I've published a proposal on it, feedback as always is we
I don't deal in protocol wars, I place lots of bets on open tech. But there's a reason I don't typically expect durable open protocols to come from VC backed for-profit. If ATProto succeeds long term — it does show promise — it'll be in spite of Bluesky PBC, and thanks to the rest of the ecosystem.
For our next Off Protocol Live, we're doing a permissioned data AMA with @dholms.at. Reply to this thread with your questions and tune into the livestream for more.

Permissioned Data PDS Lexicons
discourse.atprotocol.communityNo, I will not take part in the protocol wars on Hacker News with people who don't want to learn anything new. X is still popular, Threads is still growing, and bad actors are trying to co-opt protocols. There's bigger fish to fry. This is how it always ends anyway:
