Frequently asked questions
Direct answers on operating without a carrier, mesh range, offline Bitcoin transfer, and what BitMadWall does not do.
Communication continuity when the usual network is unavailable or cannot be relied on: infrastructure failure, disaster response, shutdown and censorship events, denied or degraded environments, and areas no carrier has ever covered. Devices relay for each other, so a channel exists wherever people are present.
No. BitMadWall operates with no internet, no SIM, and no cell tower. Devices link over Bluetooth Low Energy and Wi-Fi Direct, and over LoRa where hardware is paired. A route to the internet is needed only to broadcast a Bitcoin transaction to the blockchain, and any device that has one can do it.
The payment is built and signed entirely on your phone. It then travels the mesh like any other message until it reaches a device with internet, which hands it to the Bitcoin network. Until the network confirms it, the app clearly marks it as pending.
The message waits. A device holds the sealed message and passes it on when a path appears, including the case where someone simply walks it into range hours later. Delivery is best effort, and the app tells you honestly where each message stands.
No. Content is encrypted on the device and private keys never leave it. We operate no server holding messages, contacts, or keys, so there is nothing for us to read, hand over, or be compelled to produce.
Per hop: roughly tens of meters over Bluetooth Low Energy, around 100 meters over Wi-Fi Direct, and 2 to 5 kilometers over LoRa with line of sight. A message travels at most seven hops, so total reach depends on how many devices are relaying rather than on where towers were built.
No. BitMadWall is a closed source, proprietary product. It is free to download and use. The code is not open for contribution or redistribution.
Keys and message history exist on the device and nowhere else. Treat it as you would a hardware wallet: hold recovery material securely and offline, and use panic wipe if the handset is at risk of being taken. There is no cloud copy for us to restore.
