I’ll preface saying I’m not a security expert but my understanding Is sometime in 2025 they changed the encryption scheme in matrix following a lot of disclosures of how it was broken to a new scheme that uses MLS and supports forward secrery. I haven’t seen a post yet from security experts discrediting it yet. It sounds like it still has issues from what you’re saying, about soatok disclosing some new problems with it.

On the call side they have element call instead of relying on a jisti widget (but only a few client support it). Afaik it supports encryption. They talked about it last year at the matrix conference https://cfp.2025.matrix.org/matrix-conf-2025/talk/BQZHAH/

You’re right, I was wrong about signal using MLS. I recall reading it somewhere but can’t find the source now.

As for my response, it was about forward secrecy which they do claim to have now. Yeah I wouldn’t rely on matrix E2EE right now, and until its been seriously audited and replaced with something security experts agree on.

For a discord replacement (with public not E2EE rooms) it seems to be the best replacement just because that’s where communities are right now. XMPP+OMEMO is not that interesting to me because I don’t know of any communities that are on there or other users to be a Discord replacement and its E2EE story is not as good as Signal to be a Signal replacement.

For a signal replacement I’m not sure SimpleX or Briar are there yet. SimpleX doesn’t have multi device support last time I checked which is annoying if you’re used to useing signal on your phone + desktop. Any Briar doesn’t work on IOS, so if you chat with anyone who has an iphone they are SOL.

Does matrix have forward secrery now since the switch to MLS? (I.E. the same encryption scheme Singal uses) https://matrix.org/blog/2025/06/dispelling-myths/

They still have a large metadata leak that to my understanding can’t be fixed until they introduce stuff like pseudo anonymous user handles and room handles.

Not a good discord replacement but setting up nextcloud talk (simple p2p voice chat) and then the high performance backend (better supports video/voice calls between 3+ people) was relatively easy. We use it among my family now to have group calls instead of relying on facebook messenger.

If you use the AIO it comes with the high performance backend already set up afaik.

I run nextcloud using the official release without the docket AIO image, but you can just run the high performance backend from docker. This is what I do on my nextcloud server. https://arnowelzel.de/en/nextcloud-talk-high-performance-backend-with-docker

It’s pretty straightforward, just run docker container, if you use a reverse proxy much sure the signaling server is properly configured on the reverse proxy and then modify the next cloud settings to point to the self hosted HPB.

If OP wants voice and video chat like they say they’d have to host synapse and use element afaik.i don’t think any of the other home servers support matrix calling. Cinny and fluffychat don’t support voice or video calls. Fluffychat has it as an “option” but it’s currently broken last time I tried it. Schildi chat might work for voice and video since it’s an element fork. I’ve not tried it so I don’t know for sure.

Was this images that were auto uploading from a mobile phone? I think the bug was a permission issue in Android, if you don’t grant location access it can’t get any of the meta data of the photo (iirc).

By desktop do you mean the jitsi call widget thing? Instead of the native call support that I believe element x uses?

Do the voice call and video features work with continuwuity?

Very coincidental that you just posted this. I’ve been looking into p2p apps and Nostr caught my attention. Unfortunately like most p2p stuff it seems that most people using it are crypto affliated which is a big turn off.

The more I looked at it though nostr didn’t seem that interesting to me as a protocol compared to other p2p protocols like ipfs, Yggdrasil, i2p. Manly because it still seems to centralize around relays and the effectively ended up being your server. From my understanding its easier to move from relay to another since you can publish to multiple relays and your identify is just a key pair so your ID is “portable”. The big thing I see from Nostr is a priority to build apps on top of their protocol, compared to the other p2p protocols.

I think it would be neat if there was a non crypto affiliated social media platform built on top of a p2p protocol that did the following

• Use key identify system so your ID is portable and not tied to a single identity server
• All data is locally stored on your machine by default with the option to pin it to a server similar to the ipfs pinning servers
• Since it p2p, built with the idea that your peer maybe offline and queue sharing posts until they are online. The pinning servers could also act as an always online client for you to store messages. Like a bouncer in IRC
• No public feed, since it would be a moderation nightmare, you can only see what your followers post and what they reshare. Probably there would be feeds from trusted people you could subscribe to. This shared feeds could be a great way to build communities like in the fediverse
• Built on a p2p protocol that handles thing like NAT punch through and peer connection so anyone’s device can act like a peer without needing some server to relay messages to them, or having to port forward on their home connection. Nostr doesn’t appear to do this, since it relies on all messages passing through (and hosted by) relay servers. So your own device can’t act as a peer on Nostr.

These are the things that would make p2p social media more interesting to me than activitypub. Sadly as far as I can tell Nostr isn’t really this, and I’m pretty sure none of the other protocols I mentioned have build an app like this on top of them.
