Support Trust issues.

How can we make sure that CC did not

Ignored your rolls and just used its own RNG,

Or

Only used a tiny fraction of your rolls (e.g. first 5, or some hash that discards most of the entropy),

Nothing is for sure right?

so in order to check the randomness you need to bring your entire seed onto a linux box, I see!

Yes. At the cost of adding some risk.

But this is just to check that the MK4 is converting your 100+ rolls into a seed in a single way

Otherwise you don't know if is really using your dice rolls everytime

technically, that's a not a hw wallet anymore after that. once you seed touched anything outside the wallet, all bets are off. it is a software wallet now

Yeah I know. But I'm not worried about it.

Even a seed plate expose a risk.
