 People are trying; most notably alice has done some great work recently: https://alice.bsky.sh/post/3laega7icmi2q So now someone *can* run their own Relay (not the AppView yet, but maybe soon), and we're getting a sense of the cost and scale. This is good news; we didn't know before. 494 comments
Just focusing on storage, in July @bnewbold.net estimated the amount of storage expected to run a Bluesky relay is approx 1 terabyte. In just 4 months at start of this month (November), alice estimates nearly 5 terabytes. This is a fast growth rate and this is *before* the big post-election influx. I tried estimating how much this would cost; as a lazy approximation I dumped a 5 terabyte machine into seeing what Linode would cost to self-host, and it was approximately 55k a year: https://bsky.app/profile/dustyweb.bsky.social/post/3lah5n3kld42q That's a lazy estimate, but that's also what many people make in the US every year However @bnewbold pointed out, correctly!, that there were cheaper options available. If we used even Linode's block storage, it would be cheaper (but still expensive) for the storage component, and this is true https://bsky.app/profile/dustyweb.bsky.social/post/3lah5n3kld42q In fact @bnewbold and alice had gotten the server down to just close to $200/month in their estimate, much much cheaper than I had, by choosing a dedicated server plan. Much cheaper! But there's a problem though; that's cheap because you've got a server that has a dedicated disk... Even if we look at the dedicated hosting provider that @bnewbold provided in June and scale the cost to the pre-election storage requirements, we are adding on a massive amount of cost every month, over $400/month more.  But worse, we have reached the limits of what is possible to do with a dedicated server. We *have to* move to abstracted storage from this point forward because we're starting to hit the limits of what's offered for cheap dedicated storage on one machine. And this number will only grow, and as said previously, is growing at an enormous rate.  @cwebber honestly blogs are a more 'credible exit' than a bsky pds .. I have spent a lot of time focusing on the cost of storage, but storage is only one cost required. These estimates have been done so far against servers that *nobody is actually using*. The cost of servers that people are using will be much higher, because more needs to happen than just store things. And that is not even to mention the challenges with administrating, dealing with takedown requests, illegal content, etc, which are probably much more serious. Let's take a break, the analysis of server costs is boring and I don't like doing it, and I'm sure people will throw numbers at me of the absolute race-to-the-bottom hosting numbers they can find to store and run all this stuff, but really that's not interesting to me. Let's do a comparison. Remember that the idea of "fully self-hosting" on Bluesky/ATProto at this point is primarily abstract; nobody is really doing it. But of course there's a place where tens of thousands of people are running their own servers for millions of users, and that's the fediverse/ActivityPub. As said, tens of thousands of people are self-hosting *today*. Fediverse software doesn't just scale up, it scales *down*. GotoSocial is cheap enough on resources where you can run it for family and friends on a raspberry pi or spare laptop you have sitting around. Now you're hitting the point in this thread where some of you may be thinking "aha! this is where Christine is saying that the fediverse/activitypub are awesome and atproto is terrible!" you have NO IDEA HOW MUCH I CRITICIZE THE FEDIVERSE ALL THE TIME, I do it all the time, and will later here The fediverse has a lot of flaws. Oh trust me, we're gonna get to that. But comparison-wise: what I mean to say is that architectural decisions matter, and scaling up isn't the only thing that's important, *scaling down matters too*. If you care about decentralization, anyway. Now look, we're about 1/3 of the way done here, there's a lot more to say, and a lot more said in my article, it's about 24 pages long if you print it out. This is because in the age of TikTok I somehow have decided to model myself after David Foster Wallace, sorry "Consider the Fediverse" I guess But now, I will break for lunch. Enjoy your intermission because I will be back. We still have to get through the remaining 2/3 of the analysis, after all. ======= LUNCH BREAK HERE =======  @cwebber Thanks for doing this, it's an amazing analysis and contextualization! Okay I am back from lunch, time to resume my analysis thread for "How decentralized is bluesky really?" https://dustycloud.org/blog/how-decentralized-is-bluesky/ I have been receiving a lot of notifications, I am not reading any of them until I finish with this so bear with me, BEAR WITH ME, we're gonna make it through And before we make it any further can I say that I watched a nice medley of David Bowie and Cher singing, and it was so lovely https://www.youtube.com/watch?v=KPlN8RBP-Ws @mlemweb said "of course it's very heteronormative despite having two queer coded icons on the stage and ISN'T THAT THE WAY I guess But where was I? Oh yes. We had talked about why PDS'es aren't enough (blog/google analogy), relative costs of hosting things on ATProto vs ActivityPub, etc etc But we haven't gotten into the really interesting parts which are the structural analysis stuff, so let's move onto that Now you may be saying, "Christine, this is really unfair, because you're looking at ActivityPub servers which are only dealing with a small amount of the network, what if it were an ActivityPub mega-node? What are the costs THEN huh?" and "What if we hosted just PART of ATProto?" What then INDEED ATProto is not designed for the Relay and AppViews to only hold part of the network, not *really*, and ActivityPub is. We'll get to this in a moment. But Bluesky actually has good justification for this! I will defend it insofar as Bluesky was making a serious *design decision* Remember the directive that Bluesky was given: develop a decentralized protocol which Twitter can adopt. That informs a lot of things, and has meant that Bluesky was really very ready for this moment! If you're an ex-X-Twitter user then by god, you're going to be amazed! It's just like Twitter! This informs some other things: But here's the other thing. People have trouble with the fediverse! All those decentralization decisions get in the way, my god, you've got to choose a server, search doesn't work well (actually it could but it's a cultural thing, different topic), and worst of all: Sometimes you DON'T SEE REPLIES! Actually all these critiques of the fediverse are TRUE, these are known challenges, and actually it's not really so bad, but it could be better, and at any rate, Bluesky made a major decision to simplify a lot for new users, and they have. Things seem to just work for people! Incredible! The thing you often get seen thrown around is "it's amazing, I had no idea a decentralized protocol could just work like that! How on earth did they solve that in a decentralized system and so FAST too!" It's simple: all those things "just work" because Bluesky is centralized. Now yes, they are using decentralized techniques. Remember when I said content-addressed storage is a good idea and the fediverse should do it too? IT IS! (And as I also said, it's actually fully possible for the fediverse to do, more on that later.) But the reality is, it's still *centralized* In every meaningful way from a power dynamics perspective *EXCEPT* the category of "credible exit" (which I am saying and agreeing is a good idea!) Bluesky is centralized. MAYBE another big corporation could come along and host all this stuff but that's adding a Bing to our Google Yes, you can host your own PDS. You can also host your own blog. But try hosting your own PDS and NOT hosting a relay or AppView and you can't do much. Blogs are decentralized, Google is not. We're getting to the point where we get to why I'm so damn frustrated about this and have been biting my tongue until it nearly comes detached from my mouth: users THINK Bluesky is decentralized because they're TOLD Bluesky is decentralized AUGH! *That's* what drives me nuts. @cwebber if theres one frustration i have trying to mature a tech thing the last few years its that "maybe this could work in the future" seems to be a much much bigger draw for people than "this is actually working now and we can use it if only we do X". it suckssss. like imagine if mastodon was only mastodon.social lol Here's an example of this problem in action fry69: "The working search box was the second thing that impressed me on Bluesky, I thought that was not possible with a decentralized model" Sorry fry sixty-nine I regret to inform you the reason search works so well is that it's centralized! THAT'S WHY So hold on, let me set some terms for "decentralization" and "federation" that I think are reasonable. > Decentralization: the result of a system that diffuses power throughout its structure, so that no node holds particular power at the center. Pretty reasonable. Do you agree? I hope so! Okay how about "federation" now because this is a *technical term* that the *fediverse has established* and I'm kinda PO'ed about the goalposts being moved on this one. A lot of people coming to Bluesky have never heard of "federation" before in a social network so listen up this is important! Here's my definition of federation: > Federation: a technical approach to communication architecture which achieves decentralization by many independent nodes cooperating and communicating to be a unified whole, with no node holding more power than the responsibility or communication of its parts. @cwebber I want to be able to speak intelligently enough on the subject, but I only learned enough about Bluesky/ATProto to know that I wasn't interested in using it. Do you think it's worth understanding to be able to explain to people? And/or is there a good brief explainer somewhere? @cwebber I have kind of an axe to grind about "decentralized" systems that are really centralized organizations using some decentralized tech. People look at the protocols and cables to evaluate centralization, but what really matters are the wider trust relationships that are a layer even below those. @cwebber Dropping in mid-thread just to thank you for it! Helps me understand things. :)  @cwebber PDSes are like your house. Relays are like telecoms.  @cwebber if content addressed storage is considered a new idea then I'm done. I quit   @cwebber Have you already publish It? I Guess this is the one Where you explain if it'll be posible a federation between AT & ActivityPub @cwebber if you could convert this thread to TTS narration and attach it to some subway surfers footage I'll be set  @cwebber FWIW, there are over 1000 independent PDSes right now, and the number seems to grow at about 400-500 a month. The practical effect is different since the means to control that data beyond exporting without funky command line tools rests with the AppView, which is still extremely centralized. edit: a list + count https://github.com/mary-ext/atproto-scraping   @cwebber That's rather bad. Ideally a social media node would have a constant storage need, not one which needs to scale with the amount of users, the media, etc. Maybe ephemeral services like IRC were not such a bad idea to begin with. Β―\_(γ)_/Β― The conclusion that we need big billionaire companies, just to fill our "need" to post cat videos, is a little bit silly. BUT when considering climate change, that fits the picture. We live in absurd times. @cwebber Relevant discussion from earlier: https://bsky.app/profile/why.bsky.team/post/3lbjdux6ubc2f Non-archival relays solve some problems, introduce others. @cwebber what is in the 5TB? The whole history? Is media included? |

In fact we also have an idea of the rate of growth. Approximately 4 months prior, @bnewbold.net posted an article detailing how to run a Bluesky relay: https://whtwnd.com/bnewbold.net/entries/Notes%20on%20Running%20a%20Full-Network%20atproto%20Relay%20(July%202024)
This is great. We need more people trying to do so to get a sense of how decentralized things can be.
