#Deltachat has one of the most robust post-server-compromise threat models of any modern chat platform, and I feel like not enough people understand or talk about this tbh

@froge literally, the encryption key can never change in a chat since all the logic and data is in the clients, you can even nuke the server completely and start it fresh and most people wouldn't even notice the server was wiped 😂
not to talk about easy migration if the server is known to be compromised, all while keeping all your chats, groups and contacts
also the server can't change or drop the encryption of any chat and when you open an invite link it avoids MITM attack of the server, etc.

2@arcanechat@fosstodon.org this is, assuming you use the verified groups feature to ensure E2E chat security, but yeah it's very nice
even in the case of opportunistic encryption I think the attack surface is quite limited too
@froge oh! it seems you are a bit behind in news!!! since version 2 there is no more "opportunistic encryption chats" all chats behave like the old "verified groups feature"!!!
encryption can never drop or change!
