Important progress has been made regarding bringing MLS end-to-end encryption to the ActivityPub protocol, with developers already building implementations and providing feedback to a future version of the protocol spec.


I thought we already had Matrix
We do.
This is for activitypub DMs.
That’s what I mean.
The headline is a lie.
If I say tacos coming soon, it doesn’t mean I invented tacos, just that there will be new tacos I guess
I heard this is the line for tacos.
I’ll take one
i’m suddenly hungry for tacos
But we already have tacos.
If you say “Tacos are coming soon”. And we already have tacos. I’d say “What do you mean? Tacos are already here. Do we need more tacos?”
Do you just ask if we need more tacos? The answer is always yes… Where is your insatiable hunger?
Matrix is not really integrated into the ActivityPub protocol the same way DMs usually are. I would have to open a separate application to message you on Matrix, I can’t just click on your profile and shoot you a DM (or can I?).
You cannot, two totally different protocols
I mean, there’s nothing technically stopping one app supporting both protocols natively, especially since Lemmy already includes a field for people’s profiles to link their Matrix ID. Though to my knowledge none do it yet.
Sure, in the same way there is nothing stopping Lemmy from using ATProto. The problem is all competing standards and what the developer chooses to use.
Perhaps, but I’m describing something slightly different. Your description is basically “one platform supporting two protocols that basically do the same thing”. I’m talking more about “one app that has two separate-but-related bits of functionality, each using the more appropriate protocol for that job”.
ActivityPub is only one of a number of federated protocols.
One notably unsuited to instant messaging.
I, too, am often pissed at clickbaity, exaggerated, deliberately ambiguous headlines.
The subtitle makes it clear though: this is about ActivityPub, which has grown into the #1 federation protocol I guess.
Matrix is a poor choice from a cryptographic perspective. With some serious issues historically (some of which are still unfixed to this day), and an extremely poor response to disclosures.

Matrix is decentralized but its not federating in a way like activity pub is doing
ActivityPub isn’t the only way to federate.
Matrix is federating the same way email does. Anyone can spin up their own server. And if they want anyone can spin up their own software. That’s what federation is. Different servers agreeing on how to communicate with each other.
What??? I thought being part of Federation meant being part of the WORLD WRESTLING FEDERATION!
OOOOH YEAH, SEE I’M ALWAYS THINKIN THINKIN THINKIN, YEAH. AND WHEN IT’S ALL SAID AND DONE, WE DO THING IN THE RING! DIG IT! THE TOWER OF POWER TOO SWEET TO BE SOUR, FUNKY LIKE A MONKEY! OOOOOOH YEEEAAAHHHH!!!
Pomp and circumstance plays over the house speakers
ELIZABETH!!!
No that’s decentralization, federating is when you can share the info natively outside the platform.
I’m not even sure that makes sense.
Federating is based on protocols not platforms. And what does it mean to share natively if not using the protocol?
What do you mean?
And what benefit justifies yet another standard?
Matrix does not connect natively to discord as an example, every user of a matrix protocol is still within matrix
Activitypub doesn’t connect natively to my toaster.
How so? It’s certainly very similar.
The matrix protocol enables federation between different instances running different homeservers between users using different clients.
But all those clients are matrix, not say some discord, some fluxer, some stoat, etc.
All activitypub platforms are activity pub. Also, matrix is a protocol, not a client. There’s tons of clients for matrix (element/element x being the main one).
Yes?
“Matrix” is the protocol.
The equivalent is ActivityPub, not discord, fluxer or stoat.
