When mining...;
a) Is the block header hash of the candidate block used
b) OR the block header hash of the previous block + noonce used?
If it is a), which I presume, is it then correct that the procedure is;
- Write incremented noonce into the candidate block header
- Calculate the hash, which thus changed bc of the updated noonce, of the candidate block header and check against the target.
I looked but did not find any other question that covers exactly this.
