ℹ️ EPISODE SUMMARY
Bram Kanstein and Zach Herbert discuss the Coldcard entropy failure and why it smells like negligence, not a nation state plot. They confront how “don’t trust, verify” often stops at a slogan, even when seed generation is the whole game. They map the trade-offs between closed source, source available, and true FOSS, especially now that AI can audit firmware fast. Zach reveals why Foundation moved past pure QR air gaps, and how Quantum Link uses QR to bootstrap an encrypted Bluetooth tunnel. They zoom out to the real damage: self-custody adoption, UX vs hardcore OPSEC, and an industry that needs a rapid response loop.
