Hello,

I have looking at the source code in the function CreateNewBlock() trying to answer myself but I am unable to understand it, looks quite complicated, so I hope anyone can answer my doubts.


How bitcoin chooses the new blocks to calculate the hashes?.

it generates a random block of data and calculate the hash without taking into account if this block was previously calculated in the past?

or it generates a random block and checks if this block was never calculated before calculating the hash for it?

If I turn off my computer, could be bitcoin tomorrow calculating the same blocks than today?


Thanks!

What gets hashed?

The block is not random.  It has useful information in it, that changes often.  Every node starts over from scratch quite often.
