Dice entropy may become the new gold standard after the Coldcard hack
In light of the catastrophic low-entropy bug in Coldcard hardware wallets, linked to publicly observed thefts beginning on July 30, Bitcoin holders have started to re-evaluate the trust assumptions in their hardware wallet setups.
The Coldcard devices were equipped with apparently functional STM32 “true random number generators” (TRNGs) that rely on physical processes to produce an unguessable seed phrase.
However, after Coldcard creator NVK decided to initiate a firmware rewrite to switch from a GPL-licensed free software model to a read-only model, a serious vulnerability appears to have been introduced.
