You need to send a Bitcoin private key to someone. Not a password — a key that controls real money. Every method you can think of — email, Signal, AirDrop, USB stick — requires you to trust a middleman or physically be there. With Ghost Networks, you create a direct encrypted tunnel between two devices using device-level identity. No server ever sees the key.
The Problem
Every common method of transferring a private key has a fatal flaw: a third party can intercept, store, or leak it. You need a transfer method where only the sender and receiver can ever see the data.
Step 1: Create a Phantom Hub with Both Devices
Create a temporary Phantom Hub and add only your device and the recipient's device. This creates an encrypted Ghost tunnel where only these two devices can communicate.
Step 2: Serve the Key File Locally
Start a simple HTTP server on your device. It only listens on the Ghost interface, so only the recipient's device inside the Phantom Hub can reach it.
Step 3: Recipient Downloads the Key
The recipient opens the URL using your Ghost IP. The traffic never leaves the encrypted tunnel — no DNS, no public internet, no cloud relay.
Step 4: Stop the Server & Destroy the Hub
Once the recipient confirms they have the key, stop the server and delete the Phantom Hub. The tunnel is gone. There is nothing left to attack, intercept, or subpoena.
Why This Is Different
BiFrost Variant: When the Recipient Isn't on Your Network Yet
If the recipient doesn't have a device registered on your Ghost network, use a BiFrost Pass. Create a single-use, time-limited pass that lets them join the Phantom Hub with one device. The pass expires automatically — even if they never use it.
