I think it's a different set of tradeoffs (as is always the case in decentralized environments). So the short answer would be: yes.

Making MLS more decentralized It’s no secret that we at Phoenix R&D are big fans of the Messaging Layer Security (MLS) protocol, having helped it to come into existence. It’s a versatile group key agreement and messaging protocol ...

We made MLS more decentralized! We are excited to share DMLS that brings fork resilience to the MLS protocol, solving a key challenge in distributed systems while maintaining Forward Secrecy.

Wir haben uns an die deutsche Bundesregierung gewandt, sich am 14. Oktober gegen den Gesetzesvorschlag der Chatkontrolle auszusprechen.

Yes. E2EE would be undermined in one way or another.

There's an article making the rounds with the provocative title "MLS: The Naked King of End-to-End Encryption". It needs some rebuttal.

tl;dr - MLS is fine. This is a misunderstanding about modularity.

Not long ago, someone (who is likely the founder of SimpleX Chat) wrote a blog post about MLS that contained a pretty blatant factual mistake about MLS' authentication, including an alleged lack of security. Thankfully, @soatok.bsky.social took the time to debunk that: soatok.blog/2025/08/25/b...

I had to see for myself

We did a thing. We combined TLS and MLS into a hybrid protocol.

Why? Because sometimes you need connections that last for weeks, quantum-resistant security, or simpler certificates.

The experiment is open-source. Here's the story 👇

We really did do a thing.

Happy to announce that I’ll be speaking at @passthesaltcon.bsky.social on July 2nd!

I’ll discuss end-to-end encryption with MLS, the growing MLS ecosystem, the MIMI IETF working group, and metadata protection.
It’s my first time attending, and I look forward to connecting with the French community!

The idea that you can just “teach computer science” and be apolitical is a beautiful dream that expired in the 2000s, at the latest. Computer science has re-organized every facet of our society: it is inherently political. Instead of taking this idea seriously, we ran from it. Now we live in hell.

It's an informational draft, so I think it cannot use normative language, but adding @mallory.techpolicy.social.ap.brid.gy and @claucece.bsky.social who actually wrote this.

There has been an attempt by Knodel et al to have a more rigorous definition over at the IETF: www.ietf.org/archive/id/d...

Hey Google designers, are we sure about this new layout logo in Google Meet?

The negative space around the boxes reminds me of something.

The MLS Architecture document – the companion document to the MLS Protocol document – is now finally available as RFC 9750:

This might indeed be interesting to inform decisions about the frequency of commits. Our DS design is pretty set already, but it would be interesting to compare the details.

MLS is efficient, but what does that mean in practice?

This paper sheds some light on the question by building a test framework for OpenMLS.

Listen to it if you have time!

The latter is exactly what Apple could have done. Signal for example took that stance. And even WhatsApp did, IIRC.

Apple pulls data protection tool after UK government security row Customers' photos and documents stored online will no longer be protected by end to end encryption.

I’m deeply disappointed in Apple.
