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?
