Foundations of Blockchain

Blockchain functionality

The block linking process consists of several elements, such as creating a structure from the information, calculating the hash of the block, and appending it to the blockchain.

Let's break down each of these functionalities into blockchain methods:

class Blockchain(object): 
    """A class representing list of blocks""" 
 
    def __init__(self): 
 
        self._chain = [self.get_genesis_block()] 
        self.timestamp = int(datetime.now().timestamp()

The preceding class is a collection of class methods that create a valid blockchain using a hash function. The constructor of the Blockchain will initialize a chain by appending a genesis block, which is the first block of the blockchain, and doesn't have any reference to a previous block:

def get_genesis_block(self): ...
