This results in the output of your excel function being different from the desired one. Below is a simple python script that will illustrate it to you. import hashlib string1 = '...

I will try to explain myself with simple code. This is the hash of transaction the genesis block string versionRawTransaction = "01000000"; string numbarTransactionInput = "01"; ...


If I undestend the your question, This is an example of the proof-of-work algorithm. The nonce is a component of the block, the strucure of the block contain the value, inside the you can find the value inside the propiety "nonce" I hope I answered your question
