The project is about developing a blockchain peer-to-peer system called Cheese Coin. This is a network system which is based on the ideas of Bitcoin but simpler. In this system we have implemented the tracker to keep track of other peer-to-peer users in the network, simulating the mining feature with proof-of-work with difficulty of 0000, and auto-creation of transaction with signature.

• The blockchain of each member is stocked in a file .JSON in the folder data. You should make sure to have the same blockchain for all members at the beginning to run the test. You can download the folder data or create it by yourself.
• You need to download the files following for the interface:

  code/clientapp.ui
  code/trackerapp.ui
  code/transactor.ui
  img/bg.png
  img/bgTracker.png
  img/bgTran.png
  

You need to declare the IP address and port number for tracker, transactor, and all members. Eg.

tracker_address = 'localhost'
member_address = 'localhost'

By defaut, the port of members will be :

tracker_port = 9999 #Tracker
server_port = 10001 #Member1
server_port = 10002 #Member2
server_port = 10003 #Member3

Execute the files following:

code/Clien01_GUI.py
code/Clien02_GUI.py
code/Clien03_GUI.py
code/Tracker.py
code/transactor.py

1. Select Tracker in the combobox then click Connect.
2. Click ReqMemberlist to ask for the Member List.
3. Select AllClients in the combobox then click Connect.

1. Click ConnectTracker then Click getMemberlist to get IP address of all members.
2. Click Connect Clients.
3. Start sending transactions by clicking Start Sending. By default, one transaction will be released every 5 seconds.
