Matrix(Element)

I have questions about matrix/element.Does it leak metadata if so what does it leak?I have heard that it only shows who you are talking to but not what you are saying.

If you enable end to end encryption (not supported by all Matrix clients) then one can only see who you are talking to but not the content of the message, yes.

But Matrix leaks a lot of metadata, as chat rooms are decentralized, so they get automatically replicated on every server that has a user connected. Furthermore due to the specific git like design it is not possible to delete this metadata (so called room state) so any server connecting gets the full history of the chat room’s metadata since its creation.

Personally I would suggest to look into XMPP (aka Jabber). It also supports end to end encryption but the servers share and store much less metadata. Have a look at the XMPP FAQ here: https://joinjabber.org/faqs/

Ah, compared to XMPP with OMEMO enabled there is really hardly any advantage of Matrix in my view. But give it a try and see yourself. Selfhosting Synapse is a PITA though.

Edit: also once Movim supports OMEMO soon™, then Matrix also does not have the advantage of a nicer webclient anymore ;)

The biggest reason why I asked this is because a privacy advocate The Hated One made a video about how Signal was kinda going downhill and how he was talking about matrix for a little bit but I was thinking “Doesnt matrix leak metadata?”.

It really depends on your specific setup and thread model. I think Matrix has its place, but personally prefer XMPP. With Signal you basically hand over all your metadata to the NSA anyways, so you might as well go with Matrix then :p

ugh... lo!

Matrix saves metadata on your server, inside your database and you can disable federation, so only your server will have your data. In such case you are limited to users and groups on your server

This document talks about the issue. As of now, it does leak metadata, as already mentioned by other users, but they’re working on fixing that. The pinecone overlay network is a step towards that. A further extension to protecting user metadata they’re planning on taking is routing the messages over TOR.

Matrix is where the momentum is right now

That is also what I though, but except for client software development this doesn’t seem to be actually the case.

From a user perspective most Matrix channels I join seem largly deserted compared to their IRC and to a lesser extend XMPP equivalents.

And looking at the number of servers running, XMPP easily beats Matrix by an order of magnitude. Number of active users also seems quite a bit higher on XMPP.

So I have basically come to the conclusion that the main advantage Matrix has is their awesome public relations in open source developer circles.
