an example of how ZKP can be used to verify the identity of a user:
The user generates a random number, called the witness.
The user encrypts the witness using a public key that is known to the verifier.
The user sends the encrypted witness to the verifier.
The verifier challenges the user with a question that can only be answered by someone who knows the witness.
The user answers the challenge.
The verifier verifies the user's answer.
