The following table shows the hash obtained for selected nonce values.Another block was mined less than a minute after that - although blocks are 10 minutes apart on average, the times can vary widely.To get a lot of zeroes, you need to try an exponentially large number of nonces.The screenshot above shows what mining looks like as you get shares and blocks get mined.For block to be considered legitimate it has to have hash value lower than.Comparison of all mining pools on the official Bitcoin wiki.
