Encryption keys can be rotated automatically, but the cross-device or cross-client experience isn’t great, it often requires syncing. As for backups, the concern is losing local messages. If a new encryption key can’t decrypt past messages, then losing your local data means losing those messages permanently. Since Signal ensures that past messages can’t be decrypted once keys are lost, it effectively has the same constraint, you still need regular backups, otherwise losing local data means losing your message history as well.

I still need to spend more time learning about how group chats should be implemented, and I might not end up supporting them at all. The Signal protocol is great, but since I’ve already chosen NIP-4e + NIP-17, it’s unlikely that I’ll introduce a completely different protocol alongside them. Since the encryption keys in NIP-4e can be reset, in theory, regularly rotating the keys could provide a similar protection for most past messages.

I’m not very familiar with the Signal protocol, and I don’t have plans to support multiple protocols. Unless I decide to add group chats in the future.

It could be because the content you’re viewing includes `http://` resources. That said, jumble now blocks loading `http://` resources by default, so I might have missed something somewhere.

NIP-17 doesn’t reveal the sender.

Yeah, at the moment the wallet is tied to the app, not to individual accounts. It might make more sense to support multiple wallets and let users choose which one to use when zapping.

It sounds like you’re leaning toward a more private messaging model, something like having a dedicated contacts list and hiding messages from users who aren’t accepted. I’ll need to think this through a bit more. For now, I want to get the basic flow working smoothly first, then revisit what the right direction for DMs should be.

Yeah, it’s not very reliable right now. What you’re describing is likely due to the connection to relays dropping. I’ve been considering whether making DMs a separate app might make things more stable.

Probably just to avoid making things too complicated.
