A Minimal Chain. Blockchain is essentially a chain of blocks, and the connection is made by storing the hash of the previous block. Therefore, a chain can be implemented using a Python list, and blocks [i] representing the {i}th block. When we initialize a chain, we automatically assign a 0th block (also known as Genesis block) to the chain
