DEF COIN 34 Badge Architecture and Teardown
Bunnie Huang breaks down the hardware engineering, cryptographic features, and silicon design choices behind the DEF COIN 34 conference badge.
Summary
Open-source hardware pioneer Andrew "bunnie" Huang delivers a technical teardown and architecture walkthrough of the official electronic badge designed for DEF CON 34 [00:19].
Bunnie explains the badge's foundational open-source philosophy, highlighting how complete design transparency down to the silicon and circuit schematics enables wearers to independently audit and verify hardware trust rather than relying on manufacturer assurances [01:53, 03:32]. He describes the badge as a high-performance "go-kart for hackers," powered by a 700 MHz PicoRV32 RISC-V soft core capable of running custom binaries, manipulating GPIO pins, and driving hardware peripherals [05:07, 05:15], celebrating the creative modifications and unexpected firmware hacks devised by conference attendees throughout the con [06:51].
