BlockChain

A simple implementation of a Blockchain using Python, inspired by the work of Daniel van Flymen.

Requirements :

• Python 3.6
• Django 2.0.6
• Requests (install it via pip or pipenv)
• A text editor of your choice, the project is built using PyCharm by JetBrains ♥

Content:

• A single application chaining, which contains :
  • the blockchain.py file within the utils package. It's the core of the implementation.
  • the middleware.py file which serves to disable CSRF validation while sending POST requests.
  • the views.py the controllers that consume the blockchain.py services.
  • the urls.py the routes of our app; linked to their controllers.
    • '/chain/': "get the full chain".
    • '/mine/': "mine a block".
    • '/transactions/new/': "add a new transaction to the block".
    • '/nodes/register/': "register a new node".
    • '/nodes/resolve/': "consensus(check chain's consistency)".

Explanations :

• Please refer to Daniel's article on Hackernoon. It has a clear explanation for each piece of code. If there are some problems in the project setup please mention them.
• For testing, use two machines and run the server on 0.0.0.0 or you can test it locally by running the server on two different ports . For example : 127.0.0.1:8000 & 127.0.0.1:8001.
• Run tests using Postman or CURL.

Good luck
