Nice article about really owning your own data: « The Everything Account ». #fediverse A bit more imagination and this could work with #ActivityPub too. (See also: #atproto, @Solid )

https://www.augment.ink/the-everything-account/

Blacksky has already built their own ATProto stack that's fully independent from Bluesky.

Now Eurosky is making progress as they roll out their own PDS.

I see more independent infrastructure springing up on https://atp.fyi/network, including AppViews.

For anyone hoping that we'll get another wave of people coming to the fediverse once Bluesky folds/enshittifies, that might not necessarily be the case as people will have more options to stay in the Atmosphere.

Case in point, from a recent AT Protocol developer call:

> "choose a PDS host" is a surefire way to lose the user

Also interesting, some thoughts on sustainability and funding for ATProto apps:

> "I think eventually there are going to have to be more paid levels of atproto apps. I know I can't logically continue to burn money to support the infra indefinitely."

Reading notes from the event that mention how Twitter was an improvement over RSS in terms of user experience.

Another good example would be people switching from pirating media over to signing up for streaming services. It was the easier option.

With Blacksky recently achieving full independence from Bluesky, and other projects following behind, it'll be interesting to see who will handle federation better.

Is social media its own thing or is it an attention layer for the open web? Is it mostly about these separate things we call posts, or should every piece of writing or audio or video be able to be boosted itself?

I think that's the divide between #ATproto and #ActivityPub. #bluesky wants to dominate a world of posts like Gmail dominates email etc. Social running on a protocol but one company decides most people's experience. Or should we give the public full control over what media goes viral?

Just learned from @quillmatiqAnuj Ahooja that @msonnbergerMartin is working on #FediSky, a new project "that adds an #ActivityPub instance sidecar to a PDS"

Though there is a risk that the #ActivityPub ecosystem becomes so much of a straggler that #fediverse goes the way of bulletin boards and newsreaders (forever niche), overall the slow organic growth and evolution on the fediverse is a good thing. And #ATProto being the lightning rod for hasty commercial growth-hacking helps keep the ecosystem on that path, able to - in more protected territory - build robust foundations for interoperable standards-based social networking.

I love #activitypub but seeing how slow its development is compared to #atproto makes it hard to be excited about it. This goes for both protocol development and ecosystem development.

ATproto has many cool projects popping up every month, the vision is clear and platforms integrate with each other.

I don't see this excitement and work on the ActivityPub side :(

Interesting introduction to the differences between the protocols #ActivityPub (#Mastodon/#Fediverse) and #ATProto (#Bluesky).

https://fediversereport.com/a-conceptual-model-of-atproto-and-activitypub/

I'm somewhat inclined to disable bridging for my own account; it feels like it's providing legitimacy to BlueSky making claims about "federation" and "decentralization".

Whereas the reality is that #BlueSky is a walled garden, #ATproto has zero independent actually deployed sites, and is headed the way of it's predecessor (including political biases in post suppression).

If we enumerate possible design choices there are thousands of possible social media platforms - but is anyone actually good?

Are better experiences to be found within this vast configuration space or do we need a more fundamental rethink?

And how can we go about finding out?

@scottjenson once again going to ask that you say #ATProto and not Bluesky.

We’re trying. Like many distributed open source systems, this is bottoms up community work. Pointing at Bluesky-the-company erases our work.

It’s not Bluesky’s job, it’s the ecosystems job.

It seems there are fully hosted and self-hosted options for ATProto/Bluesky now, I stand corrected on that front.

Out of curiosity I looked into what it would take to build my own social media service on top of ATProto. The technical architecture is interesting, but... what would I actually gain?

I chose Mastodon back in 2022 when Bluesky was still invite-only and had no self-hosting story. ActivityPub is a W3C standard. Mastodon gGmbH is a non-profit. The Fediverse has years of proven independent operation across thousands of instances.

Bluesky PBC is a US for-profit company that controls protocol development, although they have made statements about wanting independent governance. Yet the network remains heavily centralized with most users on bsky.social.

Running my own Mastodon instance already gives me sovereignty. ATProto doesn't offer more of that, arguably less given the current state of things. Not saying people shouldn't build on it. But for someone already running independent Fediverse infrastructure, it's hard to see what value it would add. I didn't see the appeal back then and I don't see it now.

Based on leaked screenshots this new platform may actually be powered by ATProtocol. Here's more from @borisBoris Mann.

"Please excuse the harsh wording, but ATProto is genuinely a "privacy-last" specification where the concept of follower-approval and post privacy aren't meaningful, aside from temporarily deactivating an account entirely.

(Adding a locked account feature to apps isn't entirely impossible of course, but doing so with privacy would require at the least a parallel network with distinct architecture and protocol.)

That's not to say there wouldn't be any value in an appview- and app-side mechanism to limit exposure though, as long as it's made clear that it's trivial to circumvent with an alternative client. That may at least turn away the brunt of the harassment in such situations."

Hm, so it might actually be powered by ATproto?

https://atprotocol.dev/w-for-atproto/

Interesting.

People scraping #atproto, how do you deal with foreign key constraints? For example, it's impossible to block users from making duplicated bsky like records for same post. But relational DBs usually expect unique "like" records.

Technical details are largely above my paygrade, but it's interesting that also today, Blacksky is running an appview of its own, per @mcc (linking out to Blacksky's Rudy Frasier)
https://mastodon.social/@mcc/115917963359245981

Maybe there will be a way to stay bridged to Blacksky while remaining (ahem) defederated from Bluesky, from instances over here?

(mcc's 🧵 gives some back story here, and it [the thread not the story] begins in... September of last year)

Sometimes, I worry that I may be investing bit too much in #atproto. It's cool tech with plenty of potential, no doubt on that, but it might be occupying more of my focus than needed.

I cannot think of better example than #atproto to learn #microserivces. Like, you cannot avoid creating several microservices even you don't want to.

I keep on having a strange feeling that the Fediverse could be better.

Not just that it could be used more effectively, as yes it really could be by people. But more a factor that apps, the ability to post from one true account could be a thing.

It's been sorta proven in a way with developers building on AT Protocol with the invention of Flashes & Bluescreen for Bluesky.

Why can't we have 'one account to rule them all?' Is that even a 'good' idea?

#Fediverse #Bluesky #ActivityPub #ATProto

Mastodon and Bluesky are better than the centralized status quo. But between the two, I predict that Mastodon's ActivityPub will outlast Bluesky's AT Proto. More thoughts here: https://evanhahn.com/prediction-mastodon-will-outlive-bluesky/

#mastodon #bluesky #ActivityPub #ATProto #decentralization #tech

@bsky.appBluesky should go evil side once a year to encourage third-party solutions and show people that #atproto is actually something different.

We need general routing method under user domains on #atproto. Imagine `boltless.me/cool-repo` directing to tangled repo or `boltless.me/blog-post` directing to leaflet page. Multiple apps might want to take advantage of user domain, so it should be customizable and shouldn't tied to specific app

Bluesky "weakened" their age gate in their mobile app.

I can now see posts in the Bluesky app again.

#ATProto #ATProtocol #Bluesky #bsky #Privacy

If I try to view a post on Bluesky web-based app, while being logged in, I see the following age-gate (in the attached screen-shots) — and am prevented from seeing the post.

If I try to view the post without being logged in, I don't get the age-gate, and can just see the post.

I think Matrix still has my favorite decentralized service username schema.

@user:domain.tld makes a lot of intuitive sense to me and looks really clean. It's really clear which part is the username and which is the domain without looking repetitive. It starts with an @ so it tells clients to pull up the username lookup when you start typing, but it doesn't get kludgy like other username schemas do.

user@domain.tld makes sense for email I guess because you can't really @ people inline, but it doesn't work well for other services because it doesn't start with an @ so it doesn't indicate to the client to pull up the username lookup. I'm curious how XMPP handles this.

@user@domain.tld that Fedi uses looks awful to me. I hate the double @'s, it just doesn't scan very well and looks silly. Maybe it's just me, but I feel like my username is being flanked by boobies. (Technically Fedi uses WebFinger/the email schema under the hood from the last example and the double @'s are just user-facing in order to trigger the inline username lookup, but meh, I'm including it.)

@domain.tld that Bluesky uses seems clean on the surface, but then you realize your username is (usually) just a domain name which is... weird. Then you're stuck making a subdomain for your username if you couldn't get a dedicated domain for it, so then it becomes @user.domain.tld or even @user.subdomain.domain.tld which is just, like, idk a lot of dots. It makes sense for ATProto because of how the DIDs work, but it's still not my favorite.

I know I've made this ramble before but I'm like Fedi handles where I'm hopelessly repetitive

If you are bridging your Fediverse account with https://fed.brid.gy/ to bluesky, you can also make a custom username for the bridged bluesky handle, if you have a domain.
This is my bridged Pixelfed account:

看了这几篇文章，我又想重新托管部署bluesky了
虽然bluesky的invaild handle让我在深夜两点还在用termius的我崩溃

1. pds 个人数据服务器 https://github.com/bluesky-social/pds 继续选择docker部署
2. bsky.app在中国大陆被墙了，https://whtwnd.com/ 是类似bsky.app的AppView，但是功能风格大不一样
3. AppView自托管 每天大约需要 2.2GB 的磁盘空间，感觉开销还是有点大的 https://github.com/alnkesq/AppViewLite
4. 最好的关于bsky的解释，很高兴看到某些社交软件慢慢能够互通，又与第五条有些冲突了 https://www.reddit.com/r/Mastodon/comments/1lic376/bluesky_is_more_open_than_you_think/
5. 非常好的介绍各种去中心化服务的去中心化程度reddit例外，我很喜欢lemmy，但是单人lemmy实在太难运行下去了，除非将lemmy作为博客来写，就算这样我也只坚持了3个月 https://github.com/NoBadDays/decentralization-score/blob/main/decentralization_score_2025.04.md

在我看来bsky的自托管和去中心化确实很低，大多数都是用于逃离twitter的普通用户

The Bluesky Android mobile app is telling me I cannot use Bluesky unless I provide my date of birth.

(I haven't looked at Bluesky in a while — so, this might not be a new thing.)

I wonder if you can get around this by just installing an alternative (3rd party) Bluesky mobile app.

Operation Bluebird wants to re...

hey, #atdevs Should #atproto appview insert to db first or to PDS first? If AV inserts to db first, it will eventually do same operation again from ingester. If AV inserts to PDS first and only update db from ingester, the insertion can take longer and it can't guarantee the success.

Back to @captaincalliope.blueLyre Calliope's original pointsin this thread:

I want a new flagship #atproto app that isn't a Twitter clone on the surface.

Indeed -- Rudy Fraser talked a lot about this in his ATmosphereConf presentation. And the same is true here in fedi, where Mastodon is still dominant. I think of this in a couple dimensions

• getting beyond microblogging, but still skeumorphic to well-known centralized systems (Pixelfed and Lemmy here; Flashes, Skylight, and Streamplace in the ATmosphere). If done well, that's valiuable in terms of getting people to the ecosystem (from an activism perspective, the lack of a skeumorphic approximation to Facebook groups is a huge barrier) but my guess this is still likely to have somewhat limited impact. When was the last time when a better skeumorphic app ever really caught on and displaced an incumbent>

• less-skeumorphic software is where it really gets exciting. There's a lot of momentum here -- Bonfire, Bandwagon, Piefed are three good examples here in fedi, the stuff Blacksky is working in the ATmosphere -- but it's very hard to predict what will and won't catch on.

"I also want to see #activitypub get some of the primitives that #atproto has such as decentralized identifiers (except for real), personal data stores, content addresses, etc.

I want to see both protocols cross-pollinate with each other's strengths. And perhaps share infrastructure like identities."

Yeah, totally agree. I think t here's been some cross-pollination in both directions (Blacksky's local-only posts were directly inspired by Hometown, Mastodon's FASP and Fedisovery are somewhat influenced by AT's Relay-based architecture) but there's certainly a lot of room for improvement.

New: ATmosphere Report 145, with collections of links to interesting #atproto stuff for November

This time, all the links are on-protocol, as a Semble.so collection, with a custom page that also shows you comments on Leaflet and posts on Bluesky

Are there any combination #ActivityPub servers and #ATProto PDSs?
So one can post on both networks simultaneously?

Are there any alternate #ATProto / #BlueSky PDSs where one can make an account without giving up one's email address?

I want a new flagship #atproto app that isn't a Twitter clone on the surface. As much as I loved Twitter, I see what the result has been societally and want to move forward. Bluesky is almost a skeumorphic interface on top of atproto and I can't wait to see what's truly possible with this platform.

I also want to see #activitypub get some of the primitives that #atproto has such as decentralized identifiers (except for real), personal data stores, content addresses, etc. I want to see both protocols cross-pollinate with each other's strengths. And perhaps share infrastructure like identities.
