It is true that there are many layers of code below the OS level. UEFI for example is probably hundreds of thousands of lines of compiled code. Modern processors have Intel IME and equivalent with their own secret firmware. Almost all modern peripherals will have microcontrollers with their own compiled code.

These are all genuine attack vectors but they are not really solvable from the software side. At least for Onramp I consider these problems to be out of scope. It may be possible to solve these with open hardware but a solution will look very different from the kind of software bootstrapping we're doing.

Boot from obfuscated VM running on a FPGA softcore?

Maybe on two completely different ones and verify for differences.
