Formal verification

Formal verification is a way of making sure something is real and true. It's like checking each step in a math problem to make sure it's right. Except when we do formal verification, we use a special type of language called a "formal language" to very carefully describe what we want to verify. Then the computer will go over the steps in the language and make sure everything makes sense and is correct. That way, we can be sure that what we're verifying is really true.
