@lutindiscret@mastodon.libre-entreprise.com @aprehendedmerlin@lemmy.dbzer0.com @artiman@quokk.au @fediverse Could you please elaborate? I believe it's among the decentralized messaging platforms.

After I was arrested, I decided to change the way we promote and introduce DeltaChat. Until then, we had always presented DeltaChat merely as a communication channel for when the internet goes down in Iran, and people used it exactly for that reason. But now that DeltaChat has drawn so much attention in Iran, and even someone like me has been arrested for promoting it, I think it's much wiser to shift our content strategy. Instead of portraying DeltaChat only as a way out during internet blackouts, it's better to introduce it as a practical, everyday tool. Honestly, getting back into this kind of work is very difficult for me. But still, I genuinely believe it can be very helpful and I feel I have to do it. My goal is for ordinary people in Iran to use DeltaChat for its actual features and built-in tools, not just as an emergency app. Ultimately, I want DeltaChat to become a mainstream, everyday messenger here in our own Iran at least here and maybe, just maybe, even help people in other places too. But well, that's exactly the big challenge. #deltachat #decentralized #freesoftware

@_elena @IceCubesApp Thats so great to hear! I'd love to learn more about it too. You mentioned that nearly 10,000 users joined in a couple of weeks thats amazing! Were they all journalists, or was it a mix of journalists and people from the Fediverse who wanted to be part of a community started by them? Im really curious how it's grown since then. Thanks for doing your part to make them feel welcome! 😊

@ditol@freiburg.social Thank you for your attention. We didn't do this publicly because it would cause problems for us, but we did it privately. Well, the best solution has been connecting a personal server to Starlink, but there are other methods we need to explore on how to receive foreign traffic during domestic internet periods.

از مزار جاویدنام #علیرضا_یزدانی

من فعالیت‌هایش را از کانالش و از تعریف‌های دوستانش شنیدم و اگر دو سال بیشتر عمر می‌کرد، پروژه‌های خوبی را در حوزه هوش مصنوعی توسعه می‌داد و پروژه ربات هم‌سخن را تمامش می‌کرد.

ولی سهمش از همه دنیا یک گلوله شد و شرافت و شجاعتش و نامش برای ما به جا ماند.

خیلی سنش کم بود ولی شجاعتش بزرگ علیرضا یزدانی دولوپر هم‌سخن رو از دست دادیم به گفته نزدیکانش علیرضا بعد از هفت روز به صورت شبانه با حضور نیروهای ج‌ا به خاک سپرده شد. نامت جاوادن 💔

@delta@chaos.social To this day, while internet restrictions persist, Delta Chat has become the communication platform for a significant portion of users. There are no precise statistics available on the number of servers or users, but based on my own involvement in setting up servers and collaborating with other installers, and by averaging the user counts per server, I can estimate that over (250 Delta Chat host servers) with more than (300,000 users) are active in Iran and I know the actual numbers are far higher. This report does not mention by name all the individuals and supporting organizations involved, but I sincerely thank every member of this collective effort. This event stands as a symbol of the power of free software and community solidarity in preserving decentralized communications in Iran. به امید آینده‌ای بهتر برای ایران عزیز🖤 با تشکر از همه‌ی افرادی که در این جریان کمک کردن🙏

@delta@chaos.social As more servers came online, the user base also grew. Volunteer teams across various cities in Iran introduced and installed Delta Chat for others, inviting server owners to launch their own decentralized networks. With the addition of servers and contributors, initial issues were resolved, and new ideas were proposed and implemented by developers. For example, each server’s installation page included a section for sharing user IDs. Gradually, more extensive documentation, security solutions, detailed introductions to Delta Chat, and other practical features were organically added to the network by various individuals.

When the blackout hit, and after a day had passed, almost no access to the global internet remained—only very limited internal networks were active. Under those conditions, our public promotion and training efforts for using Delta Chat began.

First, we had to create an environment where users could install and set up the application. We set up a local GitLab instance and uploaded the necessary files there. To share download links and installation guides, we used the (Jitsi Meet) platform—because in that situation, almost no other means of communication (even SMS) was stable or available.

As many users joined the tiiiz server, it gradually began to slow down. We needed to move toward a decentralized architecture. So, with the collective cooperation of members, we encouraged the public to set up their own new servers. A simple, public server installation guide was posted on the main server, and gradually, one by one, new servers were added to the network.

Hello Delta Chat,
@delta@chaos.social

From the start of the recent protests in Iran, following the experience of the 12-day war between Iran and Israel and the experiences of the Aban 1398 (2019) and 1401 (2022-2023) protests, we knew widespread internet disruptions were coming. Earlier, active members of the free software community had set up internal Delta Chat relay servers on tiiiz.ir.
Relying on that prior experience, we conducted practical user tests with general users to observe their interaction with the application.
The result was clear: Delta Chat was far simpler for everyday users to understand and had a more intuitive interface compared to platforms like Matrix.

That’s why, together with community members, we began producing educational content for Delta Chat. The goal was to prepare users as much as possible before Iran’s internet was completely severed and localized.

@jolla@techhub.social I am thrilled to have pre-ordered a Jolla phone, and I am eagerly waiting for my friends to send it to me in Iran so that I can start using it. I know it might be challenging, but if you could offer direct shipping to Iranian users as well, I believe countless Iranian users would be keen to purchase a Jolla.
