Great ATProto blog post on the reasoning behind their design architecture

But what about the DIDs, the things used to actually identify accounts within the ATproto ecosystem:

But Bluesky has developed its own DID method, did:plc. Today, did:plc stands for "Public Ledger of Credentials", however it originally stood for "Placeholder DIDs", with the hope of replacing them with something else later. The way that did:plc works is that Bluesky hosts a web service from which one can register, retrieve, and rotate keys (and other associated DID document information). However, this ledger is centrally controlled by Bluesky.


It's literally not possible to have a functional PDS without registering with a Bluesky server and they maintain indefinite control over the ledger. All your data is tied to this DID, it's how the entire protocol is designed to identify stuff, how decentralised is your data if it's dependent on Blusky (the company) assigning you an identity?

The Fediverse is a specific thing. And even if it were just referring to any federated social network, it's very questionable whether Bluesky really can have independent instances.

The ATProto equivalent of the word "Fediverse" is "Atmosphere."

ATProto isnt the same protocol as activityhub which is what we are using to post/communicate between different instances.

You would argue that its all REST I suppose?

A community to talk about the Fediverse and all it’s related services using ActivityPub


I hope you have a good weekend.

Instead of being a patronizing ass, how about let's have some discussion about

The ultimate goal of this subreddit is a fully decentralized social media landscape.


And how ATProto is not accomplishing this / what they can be doing differently than what's outlined in their blog post

Or a counter argument to

Fracturing discussion between ActivityPub and ATProto helps no one, especially in niche communities like this.

I'm not sure that your reply is directly related to my comment. The full sentence I quoted is "Under these definitions, Bluesky and ATProto are not meaningfully decentralized, and are not federated either." by Christine Lemmer-Webber, but Daniel Holmgren talked more directly about "decentralised distribution of data".

Because of what I quoted, I don't think that "Bluesky" or "ATProto" are decentralized or federated, so it's extremely unlikely that I'll interact with them anytime soon. The particular reason that they are not decentralized or federated is not really interesting to me.

To get specific: it is a significant issue for me if "everyone can access the data but before it reaches the end users it goes through centralised applications". A "centralised application" is able to restrict my ability to contact other people, whereas with a federated and/or decentralized/distributed system, it's more likely that I will be able to contact someone that I want to communicate with. For comparison, consider how people would feel if using the United States Postal Service meant that all physical mail had to pass through the District of Columbia or if sending an email message required interacting with BBN-TENEXA just because that was the first machine to be capable of sending networked electronic mail. In the ideal case, the recipient of a message I send would not have to coordinate with me at all before they receive the message: "The first use of network email announced its own existence."

Yep. You can even go right into the source code and find out if it is truly decentralized. And right now, ActivityHub is and ATProto inst. Maybe at some point it will be (which I hope will happen regardless of bluesky) but at the moment, it is not.

Both have some P2P components but one of the big ones from ATProto:

"The answer, if you guessed it, is centralization. All direct messages, no matter what your Personal Data Store is, no matter what your relay is, go through Bluesky, the company." which you can see more clearly starting here: github.com/bluesky-social/atpr…

I tried to get one of the ATProto relays up and running but I didnt have nearly enough hard drive space to get all the data. Whereas I host quite a few federated services that include ActivityHub on a tiny server.

This is false, they support did:web which ties your identity to ownership of a DNS name (which is its own can of worms, but not controlled by bluesky like PLC).

Unless you mean that you still have to register your pds it to get indexed by the relay, so people can read your posts without querying your server directly (which is possible but discouraged). This is actually an advantage over mastodon/activitypub however, your personal pds will not crash if a post goes viral (unlike a personal mastodon instance).
