Redesigned with Native iOS Support
BitBox today announced the launch of the BitBox02 Nova, a completely redesigned hardware wallet built for Bitcoin self-custody. The device overcomes a longstanding limitation of its predecessor by offering native compatibility with iPhones and iPads. Rather than relying on software workarounds, BitBox engineered new hardware to satisfy Apple's requirements. CEO and co-founder Douglas Bakkum said, "Our customers are at the heart of every decision we make. The BitBox02 Nova embodies this, delivering a cold wallet our customers are asking for, while maintaining the uncompromising security and privacy that people have come to expect from us."
Whisper Bluetooth Architecture: Minimizing Trust and Maximizing Privacy
The BitBox02 Nova introduces Whisper, a trust-minimized Bluetooth architecture. Wireless communication is physically isolated on a separate microcontroller and logically segregated from the core wallet firmware. The main chip encrypts all outbound data before it ever touches the Bluetooth stack, and verifies all inbound communication cryptographically. Device identity remains private, with randomized addresses to prevent tracking. Bakkum noted, "Whisper silences potential attack vectors. It isolates Bluetooth function from the core system, ensures cryptographic integrity at every step, avoids remote tracking, and can be disabled by the user anytime."
Hardware Security: EAL6+ Secure Chip and Upgraded Components
The BitBox02 Nova uses an EAL6+ certified secure chip, a certification level that reflects a high standard for resistance to physical attacks. The device also includes a new display and increased internal memory, which are intended to accommodate future software updates and additional features over time.
Two Versions: Bitcoin-Only Simplicity versus Multi-Coin Flexibility
BitBox offers the Nova in two versions. The first supports only Bitcoin and runs a minimal firmware configuration, prioritizing maximum security for Bitcoin storage. The second version supports a selection of altcoins and includes functionality for universal two-factor authentication, giving users more versatility for managing diverse digital assets.
