After Coldcard: Never Trust a Wallet to Make Your 24 Words | Bitcoin Seed Security & EntropyLab | Oct. 22, 2026

The builder of EntropyLab, a single-file offline Bitcoin key and wallet calculator, argues your seed words are only as trustworthy as the entropy that created them, and that after the Coldcard failure no hardware wallet should generate your 24 words in secret. TC lays out the contradiction at the heart of Bitcoin security and the fix: roll your own entropy, create your own words, verify everything yourself. Fred Krueger answers the latest quantum panic, and Harry explains how one certificate authority's broken keys could have forged any website on Earth.
