Prefer a three-arg version (gbits-to-compare, blocknum, hash): - If <bits> is 0 or > 256, invalid. - If the hash length is not (<bits> + 7) / 8, invalid. - If the hash unused bits are not 0, invalid. - Otherwise <bits> of hash is compared to lower <bits> of blockhash. This version also lets you play gambling games on-chain! Or maybe I've just put another nail in CBAH's coffin?
