problem – Is not Bitcoin’s hash goal purported to be a a number of of two?
From Bitcoin’s whitepaper I’ve gathered that the hash of a block should begin with a sure variety of zeroes. And that this variety of zeroes is adjusted each 2 weeks. Consequently the hash goal is a a number of of two.
Requiring an additional zero for the hash perform will divide the hash goal by 2.
With that being stated, in one other query on the change (How is problem calculated?) it seems that the problem will be multiplied by fractions (e.g. 40%).
Does that imply that the hash targets aren’t essentially multiples of two? Or is the goal rounded to the closest a number of of two?
