matrix-bifrost

I was a little confused by this...maybe i'm not expert enough at networking. I initially thought this Bifrost was related to the matrix bifrost (https://github.com/matrix-org/matrix-bifrost) ...but don't think that is the case...I think because *this* bifrost seems lower in the network stack, whereas the matrix bifrost is higher in the stack, and more dedicated for puppeting users via bridging between different messaging networks (moreso at application layer)...?

tbh Matrix was pretty green 5 years ago, so you probably didn't miss much. Thanks for considering a slidge-matrix bridge. On the Matrix side, we already have https://github.com/matrix-org/matrix-bifrost as our main Matrix<->XMPP bridge, but it could definitely be better, and the more interop between open protocols the better \o/ :)

Unfortunately XMPP<->Matrix end-to-end encryption is a contradiction in terms. You have to speak the same protocol from end-to-end, otherwise you'd have to break the end-to-end encryption to translate from one protocol to the other. The closest you could get would be to run the Matrix<->XMPP bridge clientside alongside your Matrix client... but at that point you might almost as well be running a multihead messenger that speaks both Matrix & XMPP. In terms of adding Matrix to MUCs; i believe we're working on it in Bifrost, which is in active albeit slightly sporadic dev: https://github.com/matrix-org/matrix-bifrost.

Yes, there is: https://github.com/matrix-org/matrix-bifrost/wiki/Address-sy...

Clearly we just need to get Zulip talking Matrix and we can all live together in one big {Zulip, Element, Gitter, IRC, XMPP} happy family :D Edit: not forgetting XMPP via the actually-usable-these-days bifrost bridge! https://github.com/matrix-org/matrix-bifrost

Much confusion here. There are three different Matrix projects related to libpurple: https://github.com/matrix-org/purple-matrix is a very basic proof-of-concept PRPL plugin that lets a libpurple client like Pidgin or Adium or Purism's Chatty connect to Matrix. We wrote it as a demo to inspire others hoping that someone from the Pidgin community might pick it up and polish it, but sadly there hasn't been much progress. We don't have bandwidth to finish it off ourselves. Then there was matrix-appservice-purple (https://github.com/matrix-org/node-purple/tree/f5ad4ef798904...), which was a proof of concept bridge using node-purple which let Matrix connect to anything that libpurple can speak. We used it to demo bridging from Matrix into Skype via the skypeweb PRPL - but it was a very fragile quick hack demo. Then this was replaced by Bif

libpurple bridging support is being achieved through matrix-bifröst (https://github.com/matrix-org/matrix-bifrost), this is via node-purple.

Is there a way to bridge Matrix with ActivityPub? I see MXToot[1] as an option, but I'm hoping for something a little less Mastodon-specific. I'd like to be able to bridge Matrix with Mastodon, Hubzilla, Peertube, Pixelfed, and the other ActivityPub federated services that are popping up. Would it be possible to get the Bifrost[2] to integrate with ActivityPub? [1] https://github.com/ma1uta/mxtoot [2] https://github.com/matrix-org/matrix-bifrost

We have almost finished a pretty decent XMPP to Matrix bridge, if you are attached to XMPP (https://github.com/matrix-org/matrix-bifrost with a bridge running at bridge.xmpp.matrix.org). However, Matrix has a fundamentally different architecture: replicating conversation history over a full mesh of participating nodes, rather than passing messages via a star topology, and we opted to build that as a fresh stack rather than creating a mutant hybrid of XMPP.

Nobody seems to have written an ActivityPub bridge for Matrix yet, which is a shame as it'd be quite easy and really fun. (For instance, it could be implemented as a backend for https://github.com/matrix-org/matrix-bifrost - our next-gen bridge framework). https://gitlab.com/ma1uta/mxtoot is a basic ActivityPub <-> Matrix crossposting bot tho.
