Hey folks, I am building an open source air-gapped crypto vault, and as an option to not rely on system's entropy to generate random numbers, I am working on offering a "bring your own entropy" option.
This makes the system trustless
I don't agree that this makes the system trustless.
Flipping the coin 256 times is not enough to generate a public address, you still need a computer and a software to do that. This would make you need to trust that software, even if it is open source (cause I am not really going to verify the software myself).
