It's not a dumb question, not at all.
Processor vendors have been trying to tell us that they can protect parts of the CPU from its user. Intels version of that is called SGX.
There are very few good use cases of this. Also it doesn't really work.
But there are gazillion ways to attack it, so plenty of papers can be written about it.

This could be fine if the computation first goes through a consensus mechanism that tolerates faults, but could be devastating otherwise.
