differences in medium post code and github repo

[kdgosik]

Hello,

Thanks for making a nice, easy to follow tutorial! I wanted to let you know that there are a couple of slight code differences in the Blockchain object code from the medium article and the github repo. I ran into issues when trying to copy and paste the code from the article and it didn't run. After looking at the repo, everything worked!

Namely the object takes a miner_address in the article. Also the chain is used to create the genesis block instead of using the method and it throws an error.

In the article:
class Blockchain:
def init(self, miner_address):
self.miner_address = miner_address
self.chain = [self.create_block(balances=dict(), previous_hash='0'*64)]
self.difficulty = '00000'
self.transactions = []
self.balances = dict()
self.peer_b = copy.deepcopy(self.chain)

def genesis_block(self):
block = self.create_block(balances=dict(), previous_hash='0'*64)
self.chain.append(block)

Hi Kirk, Thank you for your feedback and pointing out the slight code differences between Medium and GitHub repo. I appreciate you taking the time to reach out and help me correct it. I'll make the necessary updates to ensure everything works smoothly. By the way, I have written two more articles that you may find interesting: 1.
