Title: I Have A question
Post by: nazih1997 on January 11, 2015, 01:33:19 PM
This is a proof of work question.

As I understand the algorithm, the past hash found is used to create the new hash,  but a nounce is added on the end.

Questions..

Is this nounce the thing that is changed to create a different hash?
The hashes are run until a hash with the correct amount of zeros is found, then the process starts again...

However, how does the hash get incremented? If you looked over the millions of hashes your GPU produces every second, are they all the same with a slight difference?
