Bitcoiners Turn to Dice Throws After Coldcard Wallet Security Breach
Following the catastrophic low-entropy bug in Coldcard hardware wallets, linked to observed thefts beginning July 30, Bitcoin holders are re-evaluating trust assumptions in their hardware wallet setups. The Coldcard devices were equipped with seemingly functional STM32 "true random number generators" (TRNGs) that rely on physical processes to produce an unguessable seed phrase, yet a serious vulnerability was introduced during the firmware rewrite.
This security breach has prompted the Bitcoin community to seek safer alternatives for entropy generation, with many now considering dice throws as a potential new gold standard. The vulnerability specifically affected the Coldcard's transition from a GPL-licensed free software model to a read-only model, raising concerns about centralized trust in hardware wallet security. As a result, cryptocurrency security experts are emphasizing the importance of user-verifiable, vendor-independent entropy generation methods for securing Bitcoin holdings.
