Defcon 34 Badges Feature the Open-Source Baochip Security Key

New Defcon Badges Pack a Unique Open-Source Chip That Doubles as a Security Key

I designed the Baochip-1x, a mostly open-source microcontroller embedded in this year's Defcon badges. Unlike traditional black-box chips, its transparent packaging allows infrared inspection of the silicon itself to verify security. Beyond the conference, the removable module functions as a FIDO hardware security token, offering a verifiable alternative to opaque authentication devices while promoting trust and transparency in computing.
