BitBox02 Hardware Wallet Demo
summary
Live demo of the BitBox02 shows a dual-chip architecture (MCU + secure element), microSD instant backups, epoxy-filled casing and pairing so swapped chips fail, and reproducible open-source firmware signed for authenticity. Entropy combines secure-element RNG, MCU RNG, factory random and host devrandom; wallet creation accepts dice. Anti-clepto signature protocol prevents covert exfiltration. Password hashing uses KDF stretching with erase-after-10-wrong and a 730,000 try limit on the secure chip to slow brute force. Works with Android and desktop.
