Arnacon

𝐅𝐨𝐫 𝐲𝐞𝐚𝐫𝐬, 𝐨𝐮𝐫 𝐩𝐡𝐨𝐧𝐞 𝐧𝐮𝐦𝐛𝐞𝐫 𝐡𝐚𝐬 𝐛𝐞𝐞𝐧 𝐰𝐡𝐨 𝐰𝐞 𝐚𝐫𝐞. It’s how we register to apps. How we message. How we call. How strangers suddenly know something very personal about us - forever. While building Arnacon, I kept asking myself a simple question: 𝐃𝐨 𝐰𝐞 𝐫𝐞𝐚𝐥𝐥𝐲 𝐧𝐞𝐞𝐝 𝐭𝐨 𝐞𝐱𝐩𝐨𝐬𝐞 𝐨𝐮𝐫 𝐦𝐨𝐬𝐭 𝐩𝐞𝐫𝐬𝐨𝐧𝐚𝐥 𝐢𝐝𝐞𝐧𝐭𝐢𝐭𝐲 𝐣𝐮𝐬𝐭 𝐭𝐨 𝐭𝐚𝐥𝐤? That question led us to two concepts that look similar - but feel very diff

We finally saw a bit of magic happen. A new version of Arnacon for Android is now live on Google Play. So what’s the magic? For the first time, Arnacon lets you create a temporary user - a real identity, but only for a while. You can use it to call or message other Arnacon users, and when you’re done, it’s gone. Why does that matter? Because there are so many moments where you need to talk to someone, but you really don’t want to hand over your phone number. A one-time conver

Two things are usually needed to build a successful product: a great team and a great idea. We’re lucky to have both. At this point, everything comes down to execution. Turning an idea into something real, usable, and meaningful. Not just shipping a product, but building something that actually feels right when people use it. Along the way, we make countless decisions. Every version we release, we already know that in a few months we’ll look back and think of a better way to

I’m starting a short series of posts around something we’ve just begun building: an open-source SDK called Monstera. 🪴 These posts will stay focused on one thing only: why Monstera exists, how it works, and what you can realistically build with it. That said, let's start with the why. The truth is, we simply kept running into the same problem. Different products, different requirements, all needing wallet access, key management, and APIs that don’t leak secrets or turn into

We have invested a tremendous amount of effort in making Arnacon a truly decentralized solution. Countless hours of testing and building have gone into creating systems that avoid central points of failure. It’s not a simple task - but at the right moments, it is incredibly rewarding. Our motivation is straightforward: decentralization dramatically simplifies our operational responsibilities. We rely on stable blockchain networks because, from our perspective, they represent

You can say our Domain Admin is one of the most important users in our system.He’s not just an admin - he’s the heart of a brand or a community. He is the community. Think about how WhatsApp or Telegram handle “communities.”You create a top-level hub that gathers all the related groups together - everyone can see the groups, join them, and interact. But in Arnacon , the idea of a community goes deeper.Here , every community is built around a Domain , and the Domain Admin m

Every time I try to improve my pitch about how amazing Arnacon about how it solves huge problems in telecom, privacy, and decentralization - I end up in the same place. No matter how advanced or revolutionary the technology sounds, there’s always one thing that makes people’s eyes light up: “Wait… I can make a voice call to your email address? That’s cool.” That’s it. That’s the aha moment. While I’m talking about privacy, end-to-end encryption, decentralization, identity own
