poorbitcoiner (nprofile…ajc2) If COLDCARD had used the secure elements to get random data, it wouldn't have had the disaster it did. The Linux kernel provides the main CSPRNG on the devices we use and it uses as many randomness sources as it can to feed into the CSPRNG without trusting those sources. It uses cryptographic hashes for this so it doesn't matter if one of the sources is very poor. It generates a ton of the entropy itself via timing jitter, etc.
