This post could’ve been titled “Nostr vs ATProto”, but that really isn’t what I wanted to do here. While I will be comparing and contrasting them a lot, and that’s kind of even the point of writing this, I didn’t want to really pit the two against each other at all, and especially not with the title. I also want to try avoiding commenting on the differences between the communities that have formed on the protocols and their apps, although I definitely will be looking at the philosophical differences between the two a lot - also kind of the point of writing this. This also isn’t a super deep technical post, though it assumes familiarity with technical concepts. I also might come back to edit parts of it and add more later.

Thoughts on "Nostr and ATProto" | bryan newbold

I don't know whether to be embarassed that we didn't write up something like this much earlier, or proud that thin...

From ZK-first to AT Protocol — our path to DDS | Agora Citizen Network
We've been building Agora — a platform for public deliberation using Polis-style clustering — for a while now. Along the way, we've written about what we think about Nostr, AT Protocol, Polis, Community Notes, and protocol interoperability. Those posts are somewhat outdated now. This one describes w...
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.

I am very excited about AT Protocol
AT Protocol (atproto) is the right mix of useful, practical, personal, and fun. I think it could save the internet.

OAuth Improvements - AT Protocol
We've been making improvements to the end-user and developer experiences with atproto OAuth.

#protocolsforpublishers #atproto #mcp #webapplets | Chad Kohalyk
Web publishing is facing its next challenge: a new iteration of centralizing platforms. BUT there is also a new wave of open protocols and standards that can help us gain our independence. Next month in NYC we are gathering a group of frontier technologists and popular web publishers to discuss how we can sail into this next platform shift as captains. #ProtocolsForPublishers Learn more and sign up here: https://pfp.unternet.co We will be hosting talks on #atproto #mcp #webapplets and web payments, and give publishers the opportunity to interact directly with developers working on these frontier technologies. Thank you to Unternet, Graze Social, Free our Feeds, and betaworks for their support.

OAuth is nigh! Protocol support has been a long time coming and we are pumped. It should greatly improve the user and developer experiences building secure apps and integrations on atproto. And cou...

A conceptual model of ATProto and ActivityPub
If you were to design an open social networking protocol, what would that look like? Which metaphors and comparisons would you use to get a general idea of how the network functions? And what would you answer if people ask if your network is decentralised and federated?

some thoughts on atproto as a post-app paradigm
Ecosystem Plugins
notes.wesleyfinck.orgtwo things can be true 1. `transition:generic` is too broad of scope for most atproto apps and users should be aware 2. `transition:generic` is pretty much all we got as atproto devs while more granular oauth scopes are being developed and users are fear mongering too hard too early rn

Clearsky has updated to require authentication when viewing who blocks a user, and the permission scope it's asking for via bsky's oauth is...absolutely wild. Way, way, way too many permission grants there, folks.
