What if the Bluetooth chip inside your security device were malicious?
Compromised firmware. A supply chain attack. With Passport Prime, it wouldn't matter, because we built QuantumLink.
QuantumLink is a new wireless protocol we designed from the ground up with Blockchain Commons. It encrypts every piece of data before it ever reaches the Bluetooth chip, using quantum-resistant cryptography.
Here's what that means in practice:
The Bluetooth chip in Passport Prime is physically isolated from the security processor running KeyOS. All data passing through it is already encrypted using CRYSTALS-Kyber key exchange and ChaCha20-Poly1305 symmetric encryption, both designed to withstand attacks from quantum computers.
The Bluetooth chip never sees unencrypted data. It can't read what it relays. It can't inject commands. Even if it were fully compromised, it would have nothing useful to work with.
Setup takes seconds. Passport Prime displays a QR code during onboarding. Scan it with Envoy, and a fully encrypted tunnel is established, no pairing codes, no trust prompts.
From there, you get the real-time convenience of wireless communication, interacting with Envoy, updating KeyOS, and accessing new features, without compromising on security. And if you ever want zero wireless, one tap in KeyOS powers down the Bluetooth chip entirely.
We built QuantumLink because wireless and secure shouldn't be a tradeoff.
