-    Simulates a Proof of Work mining process.
-
-    The miner must find a nonce such that the hash of the nonce starts
-    with a specific number of leading zeros (difficulty).

-        difficulty (int): The number of leading zeros required in the hash.
-
-    Returns:
-        int: The nonce value that solves the puzzle.
-
-    Example:
-        >>> result = proof_of_work(2)  # Difficulty of 2 should be fast
-        >>> isinstance(result, int)
-        True
