Computers bootstrap every time they boot, but few do it securely every time. The more complexity, in that incremental validation, the more likelihood there's a flaw.
Take iphone for example, it's bootstrapped by keys within the tamper-proof hardware tpm, then all software is incrementally validated from there. Yet jailbreaks still frequently appear.
- billytetrud 5y agoThere's a difference between saying "its impossible to do it securely" and "few currently do it securely". Also, I'm not trying to make the same mistake as the OP and claim that bootstrapping computers is at all relevant to analyzing whether PoS is secure. I'm just pointing out the absurdity of the OP's argument by showing that his metaphor trivially breaks down: reductio ad absurdum.
