Solve() 개인적인 메소드

Finds a value of nonce that makes the blocks hash lower than the difficulty target. This is called mining, but solve() is far too slow to do real mining with. It exists only for unit testing purposes and is not a part of the public API.
This can loop forever if a solution cannot be found solely by incrementing nonce. It doesn't change extraNonce.
