Nothing is impossible now. What's your feature request for Amethyst?

Good thing that I was able to implement it from scratch on Amethyst (including ChaCha20 itself) so, the audit + my own knowledge was enough to make me very confident in the approach.
Also, in 3 years, nobody has found any flaw in it to breach.

Sure.. I find the use of "forward secrecy" terms just marketing bullshit most actual engineers know it only exist in theory. So, to me, that is not a good sales point for Marmot.
I do like the scaling of group sizes, though... But I wouldn't use it because of "forward secrecy"...

2026-04-03 00:10:01 UTC

- reply

Because its not the best protocol. It's not that I have not tried...

2026-04-02 23:50:30 UTC

- reply

Forward secrecy in signal is a lie exactly because you can export/import stuff or connect with a desktop app. I don't need your keys, I just need to connect my desktop to your signal app. Then puf.. all the "perfect forward secrecy" turns into theoretical BS.

Reference Implementations.. they are way too big.. the original idea of hatcheting in tree branches is good. The implementation of the things that idea needs to have in place to run correctly is where all the problems and attacking possibilities lie. I don't think they are new problems, it's just that AI can be more effective in finding and exploring them inside codebases.

2026-04-02 23:40:01 UTC

That's a deal breaker for me. Either offer interoperability or GFO. Otherwise this is just another vendor-lock in scheme to block people from moving away from a company's products.
MLS is mostly a corporate play, so I am not surprised they have successfully brainwashed folks to think that is a feature.

It's ok, hit me up when Marmot gets audited like nip17 and has at least 2 implementations users can log in and see the same chat history.

Pubky is a platform whose company behind it holds all the cards. I did a few tests with them but was never able to build pubky from scratch because the information is not out there.

Now open this chat on another Marmot based client to see what happens.

2026-04-02 21:59:48 UTC

For starters... Your Amethyst will only ring if you are following the caller directly. Otherwise it goes to trash.

I have ~8 years of experience developing C and C++. Yeah, AI can help, but if a person like me cannot look into a code and solve this fast, the code absolutely sucks. And I have no problem shitting on it.

2026-04-01 20:45:52 UTC

Yeah, it's slower, but it is more stable once it connects for sure...

2026-04-01 20:45:21 UTC

- reply

I don't disagree with the Rust feeling, but that C Tor code is one of the worst C implementations I have ever seen. Yes, I tried to find out why the C code was running into seg fault, but I couldn't... Ai couldn't... So... Replacing it is.
Also the Rust lib is designed for embedding and sharing the app's process instead of daemon running.

2026-04-01 20:25:02 UTC

New Tor lib is up 🚀
This should solve most of the random crashing issues when coming back to the app after a while.

It's about the feeling of a native app. Unless people re-code all the little animations that match how the default apps of the phone do things, people will find it weird and reject time. I have been there many times.

Yep, it's just showing all of them together, like the main feed shows every other kind together.

2026-03-31 22:52:56 UTC

Test these too, folks. I think separating one feed into multiple types so that you can easily follow different people in each kind could be a thing. https://cdn.satellite.earth/1cb5ccf9b2ce1b4d11a3a6abe4378d2fdd7c2f8a280490b8b52d74b815db185f.png

Which version? The latest should be producing client tags..

2026-03-31 18:14:20 UTC

- reply

Only do chats. No other events. Keep it simple so that everyone can catch up and make it work...
Or make a separate NIP for each kid set people want to build nip29 for.
But definitely don't leave the kind set open to grow forever.

Such a dev thing to ask :)

2026-03-31 17:38:21 UTC

- reply

Until that is fixed, it's basically a vendor lock-in scheme: it only works if everyone in the group uses the same client.

2026-03-31 17:32:45 UTC

- reply

The problem is that chats use temporal context. If one client doesn't display an image and everybody starts talking about it, the users of that client get completely lost. Which mean that every client must support everything in nostr to make a simple conversation make any sense. And that is just terrible.

2026-03-31 17:30:21 UTC

Yeah, chats is the only thing that works.... Everything else is a shitshow.

Edge-to-edge feed just for pictures with their own Top Nav filters so that you can choose any other follow list just for pictures.
Should videos play in the same feed?
