bilal4hmed•2h ago
Compared to Signal, where does element stand today in terms of privacy and encryption? Due to the decentralized nature they werent able to offer the same guarantees from what I remember
singpolyma3•2h ago
It's exactly the same encryption tech, but a bit more trustworthy than signal.
bilal4hmed•2h ago
can you expand on how its more trustworthy than signal?
candiddevmike•2h ago
You can validate the code that's running on the client and the server, in theory
jeroenhd•1h ago
You can validate the code running on the client (well, not on iOS, but that's true for all iOS apps unless you've jailbroken your phone).

If Signal works well, you shouldn't need to validate what code is running on the server in the first place.

tredre3•1h ago
In theory you can do the same with Signal, as they source dump their server code every now and then.

If you reject that on the basis of "we can't know if it's what they're running" or "it's a partial dump", then I don't see how Matrix is any different. Not only we can't know if Matrix servers have modified software, but we also have to trust/verify several servers instead of a single one.

dijit•2h ago
The fundamental difference boiling down to trust isn't primarily in the cryptography; it's entirely down to the infrastructure and the root of control.

Signal is widely regarded as the gold standard for centralised E2EE, but its architecture forces you into two massive, non-negotiable trust compromises:

1) You must trust the Signal corporation with all your metadata. Every routing and handshake detail passes through one single choke point that they control. That is an unacceptable risk for security-minded users.

2) You rely completely on Signal to truthfully publish a pre-compiled binary that actually reflects the open-source code. For the vast majority, this is unverifiable in practice. It's a critical client-side act of faith.

Matrix’s design fundamentally eliminates these single points of failure, shifting the root of trust squarely to the user (or a group you trust):

1) Self-hosting; This is the game-changing feature. Host your own Synapse/Dendrite instance. Your metadata never leaves your control. You move the trust boundary from a corporation to yourself. You genuinely achieve "no communication outside your control."

2) Matrix uses an open specification. You can use FluffyChat, Nheko, or Element. This breaks the coupling between the server and the client. Even if you rely on a third-party server, you can use a client built by a completely different team, making the client-side code independently auditable and verifiable across projects. This is the ultimate defence against subtle backdoors in a single vendor's binary.

TL;DR: Signal offers "trusted third-party" crypto running on a single, unauditable binary. Matrix is decentralised, verifiable zero-trust communication. The comparison isn't about the strength of the AES key or which data it has been applied to; it's about the architectural freedom to not have to trust another entity with either your data or your code. That freedom represents an essential leap in trustworthiness.

You might be making good points, I'm not familiar enough with the context to tell, but whining about downvotes is in bad taste, so a large part of your downvotes probably come from there, mine included.
dijit•1h ago
Apologies, it's frustrating watching my comment go from +5 to -2 in a handful of seconds.

Not that I'm into karma farming (or that it even means anything), but it irritates me to think that people are gaming the discourse here.

There's an implicit groupthink when it comes to seeing greyed out comments; to the point that people may (and do) think that the comment is non-factual or at the very least unpopular. This is especially true in subjects that are critical of Signal.

Etheryte•1h ago
There's eight billion something humans on the planet, I think it's pretty okay if seven of them disagree with what you're saying.

jazzyjackson•18m ago
Super nice summary. Makes me want to use Matrix again, but the clients have all been very poor in my experience. Element on desktop was okay and I used it for work without issue, but it's not nearly as slick as "scan this QR code and import your contacts" (oh that's another difference, your ability to use the network is governed by Signal allowing you to register an account, typically requiring a phone number for bot prevention, which seems like an extreme step for an app that aims to keep you anonymous.)
heinrich5991•2h ago
It's less encrypted. E.g. you'd think that emoji reactions are end-to-end-encrypted (as they are in Signal). But they aren't[1]. I expect similar implementation issues wrt. the encryption in Matrix.

[1]: https://github.com/matrix-org/matrix-spec/issues/660

some_furry•38m ago
This is factually incorrect.

https://soatok.blog/2025/02/18/reviewing-the-cryptography-us...

https://soatok.blog/2024/08/14/security-issues-in-matrixs-ol...

Signal uses a whole suite of modern cryptography, including post-quantum ratchets for key agreement and zero-knowledge proofs for group membership.

Meanwhile, Matrix has a plaintext mode and knowingly shipped libraries with side-channels for years, by their own admission (and left many clients in the ecosystem depending on the vulnerable C implementation when they rewrote their cryptography protocol in Rust).

Even today, they are not the same protocol. Olm/Megolm is distinct from Signal in a lot of ways that I've outlined in my previous blog posts.

I don't particularly care if people like Matrix, but please don't spread falsehoods about the cryptography being used.

_def•2h ago
I think these two topics need to be looked at a bit separately, similar to for example WhatsApp, where you have e2ee but there are still lots of privacy risks.

In the matrix ecosystem, as far as I understand, having only one user from the matrix.org homeserver in your room already undermines metadata privacy to some degree. Also, there still are issues with decrypting messages from time to time with certain combinations of clients, rooms and homeservers, which effectively means that the "failsafe" option for getting messages across the network is using unencrypted rooms.

Having free, secure, federated, usable instant messaging is still not solved imho, and I think it's not easy to solve. So far matrix is the best attempt in my book, but it's also not there (yet?).

uyzstvqs•1h ago
> So far matrix is the best attempt in my book, but it's also not there (yet?).

IMO XMPP is the best attempt so far, but it's completely outdated by today's standards. Matrix is a modern attempt, but it's just bad. I doubt that Matrix will actually get anywhere usable in the future.

It's absolutely possible to build such a protocol with high performance, seamless UX, Signal's level of privacy and security, and Discord's level of features. It's just a lot of work to actually build the specifications and flagship implementations, compared to just building a good centralized option.

_def•1h ago
On XMPP, I agree. I think requirements also changed a lot over the years with smartphones and mobile internet access everywhere.

And yeah it's definitely possible, but it's a lot of work, both technically and from an organizational perspective (funding, governance, etc).

jeroenhd•2h ago
Matrix allows for unencrypted messages so it's inherently less encrypted than Signal. The federation capability also means messages leak metadata. Furthermore, encrypted messages also contain some metadata in the unencrypted envelope. Some protocol features (emoji reactions) also ended up outside of the encrypted envelope because of that. It's a risk with any protocol that has encryption bolted on and optional.

On the other hand, you can host your own Matrix server and still participate in the network, whereas Signal will have you convince your friends and family to install a custom Signal client if you want to run your own Signal server, for instance because you don't want to rely on Amazon's servers (Signal was down when Amazon went down this morning).

Signal sacrifices network openness for encryption capabilities.

There's also the MLS/MIMI side of things, but AFAIK that work hasn't been completed yet (MIMI isn't even a full RFC yet).

Element/Matrix, with some modifications, has been chosen as the messenger of choice by the French government (Tchap) as well as the German military (BwMessenger, BundesMessenger) and healthcare (TI-Messenger).

nxor•1h ago
Somewhat related - Can someone explain this to me? France and Germany want to lessen dependence on American organizations, so they choose Matrix, also an American organization.
dijit•1h ago
If it's open source (and libre software) then it's not as important where the main development offices are (or where the company is incorporated). You still have control.

Seems like the majority of the team are in the EU anyway: https://matrix.org/foundation/about/

nxor•43m ago
Thank you, and I see it's registered in the UK. I think it started in the US? Well, not like it's relevant anymore. And can you answer this question: If everyone has secure chat, then won't that benefit criminal organizations? I struggle to understand the love for private communication when it seems like that would benefit, for example, religious sects and sex abuse rings. NOT that I like that Zuckerborg keeping all my messages.
dijit•38m ago
> If everyone has secure chat, then won't that benefit criminal organizations? I struggle to understand the love for private communication when it seems like that would benefit, for example, religious sects and sex abuse rings. NOT that I like that Zuckerborg keeping all my messages.

Yes, sort of.

The thing is, the government is already not permitted to wiretap people, at least without reasonable suspicion.

Wiretaps themselves are not admissible in court, and can only be offered as a mechanism to correlate behaviour anyway. At least in the UK. (Which, is ironic when you consider what's going on there with online speech, but I digress).

Factually speaking, in order to do a crime you have to physically do a crime, the police knowing when and where do not require access to your communications to figure out. They will sting people, get people to turn on other people or simply catch red-handed when doing ordinary police work.

If we legitimately believe what the governments of the world are saying: that we need to embolden the police. Then funding them properly is the right start, yet nobody seems to be doing that. The EU has been making cross border communication easier though, which is in-line with emboldening the police, so I'll give them that.

Having more information will do very little to help, for the same reason that phone taps aren't given out freely (and never have been) - because even if you have the data, you have to choose how to act on it.

There is a distinct irony that unencrypted SMS is more secure than online messengers, because there are legal protections.

nxor•27m ago
Funding police outweighs the benefit organized crime may get from communicating securely ?
dijit•22m ago
Very much so.
detaro•15m ago
Freedoms tend to also benefit criminals, yes. That's kind of unavoidable.
bigstrat2003•9m ago
> If everyone has secure chat, then won't that benefit criminal organizations?

Probably. But criminal organizations also benefit from having electricity, or cars, or a million other things that we all would be much worse off if we didn't have them. Just because something benefits criminal organizations as a side effect is not really a reason to not do it for the benefit of ordinary citizens.

jeroenhd•52m ago
Matrix, the organisation, takes care of the open source side of things.

BwMessenger is a partnership with "ELEMENT SOFTWARE SARL" (according to https://messenger.bwi.de/datenschutz), the French entity of the commercial side of the people originally behind the open Matrix ecosystem (https://element.io/legal/company-information). I'm not sure why the French entity is doing business with the Germans as Element also has a German entity, but either way the American side is not the one doing the work.

For the American entity, a lot (most?) of the work that's not from unrelated open source contributors seems to be coming in from either EU countries or the UK.

nxor•41m ago
Thank you, it looks like my assumption was wrong
jazzyjackson•24m ago
Signal and any kind of Slack SaaS: US infrastructure, US law around data governance. Matrix (and Zulip, for that matter, and mattermost too) encourage self-hosting on your own infrastructure, or at least in-country, even if the upstream security patches are coming from US developers.
the_gipsy•1h ago
Signal requires a phone number, and AFAIK the PIN to prevent carrier-level attacks (well known) is not enabled by default.
basilikum•32m ago
Signal is a cryptographically well thought out protocol that reduces meta data.

Matrix does not even encrypt emoji reactions.

fsflover•19m ago
Signal is centralized, so it becomes a huge target of all kinds of hackers and three-letter agencies. This alone is sufficient for me to never touch it. And then, there is this:

I noticed that they renamed the Element mobile app to Element Classic. Has Element X reached feature parity and stability yet? For how long will Classic be maintained?
_def•1h ago
As of lately, Spaces are now supported in Element X which possibly brings it to feature parity (at least I wouldn't know what's missing, and I've been using Element X now for some months because of these plans)
noident•1h ago
> The outgoing Element mobile app (‘classic Element’) will remain available in the app stores until at least the end of 2025, to ensure a smooth transition

https://element.io/blog/mas-migration-unleashes-element-x-on...

I can't find any other communication from Element Creations other than that.

The renaming to Element Classic doesn't bode well considering that Element X still doesn't support a vast number of home servers and a number of Synapse authn/authz features.

If they remove it from the app store, my advice for my users is going to be to switch to fluffychat, and I'll eventually migrate away from Synapse to some flavor of Conduit.

Arathorn•1h ago
Element X now has initial support for threads & spaces (as of last week), which were the main things missing from full parity with Element Classic.
basilikum•35m ago
Absolutely not. It doesn't have commands and probably a lot more.

It also does not have parity by having deliberate breakage like calls.

It's a sluggish buggy mess, so I guess you could say it has parity in that aspect.

the__alchemist•1h ago
User report from 2025: Both the application and web UI are still buggy and slow. This is not acceptable in an application this simple in nature, that has been around for so long.
Arathorn•1h ago
which app are you talking about? as per the conference keynote, there are loads of different ones now, written in different stacks without any overlapping implementations.

If you're talking about the old Element Classic mobile app, then yes, it's now been replaced by Element X (which now has spaces & threads support, and so pretty much has parity with the old app), and it is super fast, and not buggy.

abeindoria•56m ago
It's not buggy? You should try going to the app store(s) and looking at reviews.
Arathorn•54m ago
again, which app are you talking about? it's like saying "the web is buggy" but not saying what browser you're using. Looking at the App Store reviews for Element X at https://apps.apple.com/us/app/element-x-secure-chat-call/id1..., there are no complaints about bugs at all (only missing functionality, which has since been added)?
the__alchemist•25m ago
Hi! I'm referring to the one on element.io/download marked "Desktop" I haven't tried element.x. Seems to be phone only?
jeroenhd•44m ago
The only desktop messenger with smooth performance I'v used was Telegram. Signal, WhatsApp, Element, and all the other Electron applications all introduce hard-to-pinpoint latency somewhere. Unfortunately, Telegram is... Telegram.

For XMPP/Matrix/etc. there are plenty of (more) native alternatives but they're not as feature complete as Telegram or their Electron counterparts, unfortunately.

My lack of C++ and Qt experience has still managed to keep my urge to rip out the Telegram protocol and replace it with something else. Maybe I'll try throwing AI at the problem and release a slop POC. Secretly, I'm hoping someone else will do the hard work for me...

The mobile apps for all are fine, though. Electron hasn't hit mobile phones just yet.

jazzyjackson•6m ago
I use thunderbird for email and they now let you connect to matrix, irc, xmpp, and whatever Odnoklassniki is. It's quite barebones however, like it looks like people are just adding lines to a google doc, barely any interface at all. Really a stylesheet would go along way, looks like userChrome.css works, so maybe I'll mess with that.
