Public service announcement:

1. If you want to link your #Fediverse profile to a chat account please consider just saying "DM me for #deltachat invite link" and NOT PUBLISH it to "all".

2. If you do publish invite links to groups and so on, please consider doing it with a dedicated delta chat profile that is not your private profile. Multi-Profile for the win.

3. We want to evolve the #securejoin invite link UX to better prevent unsafe practises. Involves tons of considerations. 💜

With our #deltachat #chatmail and #webxdc efforts we put all intelligence on the end devices, and architecutally separate it from a transport layer that routes safely and fast but knows nothing.

There are a dozen or more #chatmail servers across many jurisdictions, all safely interopable with each other and classic servers.

Turned out we can dumb down email servers by relying on cryptography instead of IP reputation and ai/spam filtering. And have 200ms delivery times. We are not done :)

Did you know that #deltachat does not need and does not use key servers? Most other messengers (wa/signal/matrix/threema/...) actually operate or incorporate a cryptographic key server, managing the cryptographic identities of all users. Delta Chat uses decentralized protocols for key management avoiding a central storage of identities. The SecureJoin protocol is the key (sic!) innovation and was independently analyzed by ETH Zürich researchers earlier this year .... https://delta.chat/en/2024-03-25-crypto-analysis-securejoin

How many people do you know that have lost their messaging history on Whatsapp or Signal, photos etc during mobile phone transitions or breakage or through other shenenigans?

With #deltachat you can:

- export "everything" to a file and import it on any of the many different devices

- or just setup a second device through a QR code scan -- which was happily discovered here after an accidental factory reset https://libranet.de/display/0b6b25a8-2066-0695-ca24-081964494389
