How can you make sure that the open source code is running on the server?

Question

open source

I understand that the question is too general, but still. Is there a protocol/technology that helps others prove that the server they are accessing is running the exact same code that is open source? Is there any such practice?

Answer 1

No.

Answer 2

This protocol is called a contract or offer.
In it, you can make the points that you use only software with certain licenses, and provide a list of this software.
