This week, Coinkite disclosed that certain Coldcard devices generated recovery phrases with weakened randomness — and updating the firmware doesn't fix a seed that's already out there. Coinkite's founder NVK called it "heartbroken" territory in a public apology, and committed to full transparency on how it happened. In this episode, I break down exactly what went wrong in the code, why it slipped past review for years, and — most importantly — the exact steps to check if you're affected and migrate your funds safely. This is the episode you send to anyone you know holding a Coldcard, especially if they're not glued to crypto Twitter. Every hour matters. ━━━━━━━━━━━━━━━━━━━━━━━━━━ ⏱️ TIMESTAMPS ━━━━━━━━━━━━━━━━━━━━━━━━━━ 0:00 Cold open: what happened and why it matters right now 0:45 Intro 1:30 The short version: what actually broke 3:15 How bad is "weaker randomness," really 5:00 Coinkite's response: NVK's statement and accountability 6:45 How the bug hid in open-source code for years 8:15 Exactly what to do if you're affected 9:45 Two habits to keep permanently 10:45 Close: help spread the word ━━━━━━━━━━━━━━━━━━━━━━━━━━ 📖 SOURCES & FURTHER READING ━━━━━━━━━━━━━━━━━━━━━━━━━━ Coinkite's official advisory: https://blog.coinkite.com/ NVK's full statement: https://x.com/nvk Full written breakdown (this episode's source article): [link] ━━━━━━━━━━━━━━━━━━━━━━━━━━ 🟧 SUPPORT THE SHOW ━━━━━━━━━━━━━━━━━━━━━━━━━━ 🟦 Blockstream Jade – The BEST Bitcoin hardware wallet.
