#deltachat

you too can make email fun again. it's just a transport. use it!

if you need help setting up, let me know. also if you want to run your own chatmail/mail server, my dms are open

✨ My first technical blogpost is out now. ✨

If you ever wanted to learn a bit about how
#deltachat works internally and why we have two ways to communicate with our #rust core, then this is the introduction to read

head-ups #DeltaChat users! Want to help us testing the upcoming Delta Chat 2.X release? read here:

We'd like to remind everyone that a self-hosted #chatmail relay is best shared in some wider than family circles. In crisis situations everbody does better when helping others.

A typical 1gb RAM chatmail relay VPS for 5-10 eur per month supports 50k+ daily users.

chatmail VPSes are stateless. You can wipe all disk state, reinstall and chatting will resume. Conversely, #deltachat does not keep or depend on any server state .Operators under pressure do not need to feel bad to hand over data.

La idea de pasarse a XMPP ya como que me remata, porque todo el trabajo de pasar a tu entorno recae en el que lidera la propuesta y para eso hay que tener entusiasmo y fuerza.

Tuve una época en la que estuve usando #deltachat con el correo electrónico y si hay que hacer esfuerzos en promocionar sistemas (en mi opinión) es en el correo electrónico. Mecanismo que empezamos a perder porque todo el mundo tiene uno, todo el mundo lo necesita, pero nadie quiere pelear por el suyo. Igual que con el fediverso.

1 cent per five years .... is the current marginal hosting cost for a #chatmail address, with which #deltachat apps facilitate world-wide private messaging including interactive #webxdc apps that run end-to-end encrypted in any chat group.

<1 Million EUR per year is the estimated marginal hosting costs for 350 Million EU citizens. Such scaling requires, however, research and development, including careful UX and #cryptography work. Related writing from @gordon

screenshot of key excerpt from the referenced post: "When the network is built on cryptographic protocols, we don’t have to trust anything in-between. We don’t have to trust the computers, the wires, the institutions, beliefs, or kinship of the network participants. We can trust the math. All we have to do is verify the message with cryptography. This is a powerful primitive for scaling trust, because it means everyone on the network can cooperate together, even if they don’t trust each-other. The costs to producing high-trust results are greatly reduced, and we can spend our coordination efforts on building larger, more fine-grained, more complex networks of cooperation."

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
