You’re right, the interoperability means you can communicate in the same group between Whitenoise and 0xChat, but the MLS state on different devices and clients is stored locally and can’t sync.
However, maybe in the future, we could enable transferring that state to other clients or devices in a secure way, such as encrypting it and transferring it via Bluetooth or local network.

2025-05-30 15:29:35

Now, when creating a group in 0xChat, you can choose MLS encrypted group chat. It now supports adding and removing group members, as well as leaving the group. However, modifying group details is not yet supported.
This implement follows NIP-EE (https://github.com/nostr-protocol/nips/blob/001c516f7294308143515a494a35213fc45978df/EE.md).

Is there a way to ensure that the events returned by the subscription are ordered by created_at in ascending order?

2025-05-21 04:34:10

- reply

A NIP-29 relay not only forwards messages, but also maintains and synchronizes group state.

why? 😂

2025-05-21 02:39:19

- reply

Pulling group messages from multiple relays is technically fine. But can we really say these relays represent the same group? For example, relay1 might show 3 members, relay2 has 4, and relay3 might already consider the group disbanded. In this case, the group messages you receive are unreliable.

2025-05-21 02:26:05

- reply

Unlike notes, group messages rely on group management, and keeping group state in sync across multiple relays is very difficult — if not impossible.

2025-05-21 02:14:02

- reply

Currently, it's not supported. Personally, I prefer using a single relay for group chats. The main advantage is message stability and consistency.
The downside is the single point of failure — but I believe this can be addressed by implementing a backup and migration mechanism to move the chat history to a new relay if needed.

I think this is a problem with fiatjaf's implementation, not a problem with NIP-29 itself.

Thank you for the suggestion. After the lite version is completed, I will provide some insights on the security and privacy.
If there is a steady revenue, i will also conduct third-party security audit.

2025-05-17 15:03:21

I'm fully focused on developing a 0xchat lite version, using MLS for private and group chats, with a streamlined set of features and a simplified UI. How do you think?
I'm also gathering suggestions for the lite version, feel free to share any ideas.

2025-05-16 14:34:59

- reply

I agree. Additionally, if the user just wants to display the nevent string instead of a nostr: link, it would become very difficult if every nevent is recognized as a link.

2025-05-16 03:53:35

- reply

Not yet, but I can add support in 0xChat Wallet for invoice deep linking. Once Amethyst supports jumping to 0xChat, zapping via your 0xChat wallet would be possible.

Is it that you cannot receive video calls, or is it that the call connection doesn’t work? If you can’t send pictures, you can try changing the file server in the settings page.

I’m using the library from this repo: https://github.com/parres-hq/nostr-openmls — but I’m not sure if that’s the old one or the new one.
What I’m mainly looking for are group management features, like adding/removing members or updating group info.
Also, really glad to hear encrypted media is coming to NIP-EE — looking forward to that!

2025-04-30 15:45:28

- reply

I’m using that bridge in 0xChat, and it makes it easy for other Flutter apps to add MLS quickly.

2025-04-30 15:42:28

- reply

Congrats on the update! Do you have any plans to improve group management in the nostr-openmls library? Really looking forward to that. Also, I saw your mention of encrypted media in the report—are you following an existing NIP for that (like NIP-17), or is it based on a new nip?

Yeah, that’s a big possibility. It could also be that if you’ve logged into multiple accounts before, the notification might be from a different one. Or it might just be some other bug with the push service.

Maybe you haven’t connected to some relays, and the messages are on those relays you’re not connected to.

Yes, my idea is to build 0xChat while also sharing independent libraries like Nostr Dart and Cashu Dart with the community, so I split them into multiple repositories.

0xChat is implementing MLS, more specifically NIP-104(Nostr MLS), which will be compatible with whitenoise client.

2025-02-24 07:43:22

- reply

It’s not a bad idea imo, but rather a trade-off. Sharing the device key increases the risk of leakage, which goes against the intention of forward secrecy.

2025-02-24 05:56:02

- reply

The default DM will still be NIP17 (supports sync across different devices/clients), while secret chat and private group will be replaced with NIP104 (does not support sync across devices/clients).

2025-02-24 05:35:20

Currently focused on:
1. Upgrading 0xChat Flutter framework to the latest v3.29.0, progress at 80%, feeling great!
2. Building secret chat based on NIP104, bridged with the mls rust library from @nprofile…hppf , progress at 50%

2025-01-08 11:02:22

- reply

Emm, I don’t think this is nonsense. Have you checked NIP-51? Items can be either public or private (encrypted). If the client you’re using doesn’t support private items, then it hasn’t implemented NIP-51 properly.
