Blockchain Introduction

In this article, I’ll make a simple blockchain in less than 50 lines of Python 3 code. It’ll be called SnakeCoin. We’ll start by first defining what our blocks will look like.

In blockchain, each block is stored with a timestamp and, optionally, an index. In SnakeCoin, we’re going to store both. And to help ensure integrity throughout the blockchain, each block will have a self-identifying hash.

Like Bitcoin, each block’s hash will be a cryptographic hash of the block’s index, timestamp, data, and the hash of the previous block’s hash. Oh, and the data can be anything you want.

Installing required packages

import hashlib as hasher
import datetime as date

How to run

• Through Terminal, please run this line of code

python snakecoin.py
