@quillmatiq @mike @mmasnick

Feel like whenever this discussion is joined people start talking past each other.

It may be the case that the ATmosphere can be decentralized. And there may be small scale projects which test this potentiality. But the fact remains that it remains highly centralized.

Rob Ricci @ricci has developed a metric to address this matter

Are We Decentralized Yet?

A site with statistics regarding how concentrated user data is on various web services

(arewedecentralizedyet.online)

The purpose is not to dump on #Bluesky, but rather to establish meaningful context for these discussions.

@quillmatiq @mastodonmigration @mmasnick Can they post to each other?

@mastodonmigration I was specifically calling out not moving the needle, which the community (and Bluesky for that matter) most definitely is. There are far more fully independent apps and infra in the ATmosphere than folks here give credit for.

I'm not getting into the normal "decentralization" conversation because, yes, we'll talk past each other, and it's difficult to have a meaningful discussion about it here.

@mike @mmasnick @ricci

@mike @mastodonmigration @mmasnick @quillmatiq this is partially true: yes, there are tons of cool atproto apps, and I'd say they span a wider range of things than are on the fediverse.

On the other hand, not all the things you mention as full stack are actually full stack, or even operational. They are also pretty small, so far. If you want to see how large some of these alternatives are, you can check out the "raw data" link under the Atmosphere on https://arewedecentralizedyet.online/

@mike Yes. There's standard.site that's being worked on across the blogging platforms I mentioned, and there's lexicon.community, which is an independent board that helps simpler interop happen.

Apps can also interop with the permission of the user by using the data in their PDS. For instance, blento.app uses a user's data across apps to build a webpage of all your ATProto content, and they didn't have to work with any of the apps directly to make that happen.

@mastodonmigration @mmasnick

@ricci the only one I mentioned that isn't fully operational is Offprint, but even that had it's first blog launch this week.

Why would you say they're not full stack?

@mike @mastodonmigration @mmasnick

@quillmatiq @mike @mmasnick @ricci

Understand that there are a lot of interesting and creative things going on with AT Proto.

The reason for referencing Rob's AWDY metric is to help with convos like the one between you and Mike. That is, he states it is not meaningfully decentralized and you reply with a list of apps and projects. He's talking about ground truth and you are addressing technological potential.

Perhaps decentralizable and decentralized, although that let's a lot of pushback.

@mike @mastodonmigration @mmasnick @quillmatiq eurosky isn't running anything at all so far, not even a PDS so far as I can tell. Northsky runs a PDS, but uses Bluesky's relay and appview. I don't know about the others, except to say that they don't show up in the largest PDS lists.

Blacksky is the only one that's credibly full stack, and they opened beta access to their appview literally days ago.

There is a lot of buzz, and there is real stuff behind it, but it's also important to look at actual status and track it over time

@ricci oh! I specifically said "coming up" for that reason. My bad for the misunderstanding of your earlier reply.

@mike @mastodonmigration @mmasnick

@quillmatiq @mike @mmasnick @ricci

So, while you are all here perhaps we should mention the issue of whether AT Proto is in fact really even "decentralizable".

The issue has been raised by @cwebber as to how the network scales geometrically as it goes wide. Have not seen anyone refute this.

This would render any real efforts to broadly decentralize effectively impossible. Have not seen anyone address this analysis.

Anyone?

@mike @quillmatiq @mmasnick hey Mike Fraser you were in the audience when I gave this talk at #Fedicon weren’t you?

Beyond Microblogging: AT Protocol for Building Unique Social Apps

I gave this presentation at [[Fedicon]] 2025 in Vancouver.My goal was not to do a protocol deep dive, but rather showcase all of the beyond microblogging app...

Boris Mann's Homepage (bmannconsulting.com)

It has a list of some of the many projects in the ATProto ecosystem

Please don’t erase the #ATProto community. We’re on the same side.

@mastodonmigration @quillmatiq @mmasnick Which raises questions.

If this network is profiling with photo verification etc for all users , will it allow people to connect with other parts of Bluesky, where there are bots or unverified accounts? If so, the purpose is lost. However, if it remains closed to other parts of bluesky, it will most likely be isolated. I don’t think this will take off either way .

@quillmatiq @mastodonmigration @mmasnick @ricci My original comment was more about moving the needle in terms federated decentralized applications. No one Denies there's activity in the Atmosphere but does it fulfill the promise of independent but federated social media. In my mind it hasn't reached that high water mark.

@quillmatiq @mike @mmasnick @mastodonmigration by the way, I posted the Atmosphere equivalent of this map over on Bluesky, or you can load the map and play around, it's interactive and lets you select between the social networks and apply other filters

Rob Ricci (@ricci.io)

Launching their new social network, W, the EU posted a map of where other social networks are hosted. It showed nothing in Europe. But their map is wrong. Here's what Bluesky and the broader Atmosphere actually look like arewedecentralizedyet.online/map/?source=at

Bluesky Social (bsky.app)

@quillmatiq @mastodonmigration @mmasnick So interop is being worked on through third parties? There's different interop for different applications?

@mike Yup - highly recommend reading up on Lexicons in ATProto!

If you want a really deep dive, I'm a fan of Kuba's breakdown of the system: https://mackuba.eu/2025/08/20/introduction-to-atproto/

@mastodonmigration @mmasnick

@boris @quillmatiq @mmasnick I was Boris, I'm just not sold on atmosphere as fulfilling my personal requirements for an independent federated space. Simply too many roads run through BlueSky which I feel has been captured. In any other time I wouldn't be as sensitive to this as I am now however my country is under existential threat and I simply don't feel that atmosphere can be trusted. The fediverse though not perfect self regulates more effectively and independently.

@mike @quillmatiq @mmasnick that’s fine - but “not really moved the needle” is incorrect - there’s a sample of a dozen or so apps, out of many more.

All using the same protocol just like the AP ones you listed.

Go yell at Bluesky! It’s a company! They can do what they do and you can disagree.

The #ATProto community is building bottoms up.

It’s like saying you aren’t going to trust the email network because Gmail and Office365 are involved in routing email. This is how protocols work.

@mastodonmigration @quillmatiq @mmasnick Why not use a true and tried European (distributed) social network like Mastodon? Seems like a no-brainer to me.

@boris @quillmatiq @mmasnick My comment is not simply in regards to the number of apps. It is in the number of apps that truly federate between each other and in heterogeneous environments. My original comment was meant to convey that BlueSky/AT folks often talk a lot about dectralization and federation but from what I can see from the outside looking in it seems like lip service.
