#deltachat

#deltachat is secure against server-side group membership changes but for a very different reason than #signal which keeps encrypted group membership data in a central store.

Delta Chat has _no_ central store but implements a rigidly tested #p2p group membership model where servers play no role https://github.com/chatmail/models/tree/main/group-membership

Both signal and delta chat are safe against recently published attacks against #whatsapp that can add members to chats, breaking end to end encryption. https://arstechnica.com/security/2025/05/whatsapp-provides-no-cryptographic-management-for-group-messages

#DELTACHAT TODAY

#Deltarune

#Whatsapp afirma seguretat del contingut d'extrem a extrem, però:

- Vincula la teva identitat a un número de telèfon

- Controla la teva identitat

- Pot veure qui envia missatges a qui, qui hi ha en qualsevol grup, etc.

- T'obliga a enviar a la IA de Meta les teves cerques locals en els teus xats privats

- No permet deshabilitar la AI de Meta en la pantalla principal

Cap d'aquests problemes existeixen amb #DeltaChat

What I really like about #DeltaChat / #Chatmail :
- no admins in groups. Groups without trusted people make no sense. Anyone can delete anything. It's more like a messenger for friends and family. It's a “feature” that I really like

What I don't like:
- not possible to pin messages (I read it's coming)
- webxdc is nice, but without pinned messages it's annoying to search the history for them
- moving profiles (I read it's coming)

What I really like about #DeltaChat / #Chatmail :
- no read receipts (optional)
- delete history/automatically delete (optional)
- save messages only on the device
- super easy setup (really! super easy!)
- no need to save credentials (but it's better to save them if you want to reinstall things often)
- easy setup for the second device. Just click on "Add second device"
- chatmail is super easy to maintain. No group admins make it even easier!
- desktop and Android app

For some reason I cannot run a chatmail relay for @delta@chaos.social.
I follow the guideline from its GitHub-repo, but here's my output on the final step:

Parlant de #DeltaChat, estic content perquè ja hi tinc la meitat de la meva família.
Els sorprèn la facilitat en crear-hi un compte i la seva funcionalitat, molt senzilla de fer anar.

#whatsapp claims end to end security of content but:

- ties your identity to a phone number
- owns your identity
- can see who messages whom and who is in which group etc
- forces you to send local search in your private chats to Meta AI
- does not allow to disable Meta AI on the main screen

None of these problems exist with #deltachat devs and distributors. We have arguably the world's easiest onboarding process for a messenger that offers a Whatsapp style interface on all platforms.

#DeltaChat #Descentralització

@descentraliza i #deltachat ?

#deltachat - https://github.com/deltachat must see it!

Был одним днём (где-то после 2020) на автовокзале Ростова-на-Дону, там была столовая, и на столе красовалась какая-то визитка с QR-кодом для Delta Chat. Я ещё тогда понять не мог: что это, кому это? А сейчас такой сижу и думаю: нифига, какой прогрессивный люд, в дельтачат ведь приглашают вместо этих ваших телеграмов, круто.

#DeltaChat

@delta
Unsere Familien-Chatgruppe ist seit zwei Wochen bei #DeltaChat. Das funktioniert für alle, und eine erste Terminabstimmung über eine #WebXDC-App hat ebenfalls stattgefunden. Danke an alle, die #DeltaChat zu einer funktionierenden, unkomplizierten und föderierten #Messengen Alternative gemacht haben!

@delta @komun just moved from our unofficial Telegram group to a much private a descentralized #Deltachat , so far so good, some use relays and others their own emails.

@delta Ilove #DeltaChat... I collaborate with a small chatmail in delta.cuates.xyz

To Καφενείο group στο #deltachat με καθημερινό wordle, miniblog σας περιμένει.

@ex_06 For now, #deltachat will stay focused on private messaging and rather serves as a decentralized alternative to Signal and WhatsApp although the latter is turning into a social media / AI app which we are not aiming to imitate.

Если вам нравится Delta Chat и вы хотите узнать почему мы внезапно стали очень популярны на Кубе и в США, вот небольшое объяснение (циферки, графики, статистика).

#deltachat

Since June 1st there is a big sudden surge of new Delta Chat users and so far things are going pretty smooth. We are happy that our #chatmail infrastructure is holding up and that there is growing recognition that #deltachat is a ready-to-use and resilient chat solution. Some stats from the last days, a brief discussion of centralization risks and what we plan to do about it, also introducing a brand-new chatmail OpenCollective with a european fiscal host.

@MxVerda @BrodieOnLinux @qdot Well, depending on what you want to develop or communicate there are various options.

Many folks went from #GitHub to @Codeberg / #Codeberg to do their #FLOSS development as it too has #IssueTrackers and means to discuss things without #loginwalled read-only access. Others like @torproject have their own @gitlab / #GitLab servers #SelfHosted.
If you want a #Chat then consider #LiberaChat if you don't demand #privacy. Otherwise @delta / #deltaChat and/or #XMPP via @monocles & @gajim may be an option.
If you do want some #LoginWalling for some reason, consider @zulip / #ZulipChat as it has a nice #threading model that can handle both asynchronous communication and high traffic without becoming unfindable or unarchiveable. Otherwise there's like @RocketChat / #RocketChat which also works great by my own experience.

Case in point: #discord just makes it more cumbersome and painful than anything. It's basically #Slack + #MicrosoftTeams, but worse…
