I appreciate your honest feedback — and I understand your hesitation.
I agree: most so-called "offline crypto" solutions today just mean signing on one device and broadcasting later via QR or USB. What I’m working on includes the full peer-to-peer transmission layer — without using traditional proximity-based channels like Bluetooth, NFC, or LoRa. And yes, the distance is global — not just short-range.
I'm intentionally vague about the core method here, not because it’s vaporware, but because the system is still under private protection and not public domain. That said, I’m happy to show more (privately, under NDA if needed) to people who are serious and experienced — like yourself.
Whether it ends up being revolutionary or just “novel but niche,” time will tell. But it’s fully tested and working as of now.
Appreciate your time, and your reply. you can contact me if you want by email
aristotelis187@gmail.comIt sounds very interesting, at first I thought it uses camera or microphone to send data between mobile phones, but I saw that you mentioned it is not short range.
I am wondering if your system uses some external device that allows mobile phone to connect to other mobile phone over long distance?
Thank you for your thoughtful question — and I really appreciate your open-mindedness.
You're right: it's not using camera, QR, microphone, NFC, Bluetooth or any typical short-range or direct pairing method.
And no — it doesn't rely on any external hardware or custom antennas to link two phones over long distance either.
That’s where I believe the true novelty lies.
What I’ve built leverages an existing, globally accessible communication layer that works even on basic mobile phones, across long distances, and in infrastructure-limited environments.
The key here isn’t just offline signing — it's how the TX data is encoded and moved from an airgapped phone all the way to the Bitcoin network, without ever touching internet, WiFi, or mesh networks on the sender side.
It’s fully testnet-verified, and I’ve already successfully broadcasted signed transactions from offline to on-chain.
I hope to be able to share more when the system reaches full maturity — right now I’m tightening up the automation, stability, and protection before revealing any details publicly.
Thanks again for asking — the fact that you didn’t dismiss it outright but looked deeper means a lot.
