No matter how beautiful and cool a billboard is, it will expose its sloppy appearance after a few years.
The owner of the signboard wants to repair the worn-out signboard. It’s not unnatural for owners to decide that they want to repaint a part instead of updating the whole thing.

How can it be proven that a verification task is valid?

The task of verifying something is relatively easy. Because it’s just about verifying something.

The work must be verified for it to be proven. In short, one verification work is verified from another point of view.
