Easier interoperability between these two open protocols is exciting.

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.

shreyan - Nostr and ATProto
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.

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.

PostgreSQL Extensions or Protocols: Architecture Roulette
Should new infrastructure use PostgreSQL as a query engine, or aim for protocol compatibility instead?

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.

Another reason why it’s so important that we have open protocols for social media.

One of the issues that has come up again and again in my reporting on misinformation and social media is the massive influence social media companies have on research in the field. Last night a preprint dropped that tries to get at this with some numbers. My piece in @science.org (and 🧪🧵 coming):
I've been thinking about the beauty of open data and how the AT Protocol and wider Atmosphere ecosystem has been recapturing that open data environment that once defined the web. It really does feel special. vale.rocks/posts/atproto-ethos #atproto #ATProtocol
