HardvardIt

Validate the integrity of your student records using THE BLOCKCHAIN.

Requirements

• Python 3.6 (you can use a virtualenv using virtualenv -p python3.6 env && source ./env/bin/activate)
• POA or POW Ethreum-based environment (Quorum, Rinkeby, Kovan, Ropsten)
• Python dependencies defined in requirements.txt. To install them use pip install -r requirements.txt

Setup environment

• Install requirements
• Run migrations: python manage.py migrate
• Define the connection settings to your blockchain node at ./harvardit/harvardit/eth_settings.py. You can use this template:

eth_host = 'http://localhost'
eth_port = 22001

default_pass = 'Passw0rd'
default_gas = 4000000

initial_ether_transfer = 0

# Only if initial_ether_transfer > 0
coinbase_address = "*"
coinbase_pass = "Passw0rd"

POA = True # Set to false if the consensus used is PoW

Use app

• To run the app from the root of the repository run cd harvardit && python manage.py runserver.
• Go to http://localhost:8000 to start using the app.
• Create a new Universities, Professors and Students, and start playing with the system.

Inspect student contract

If you want to inspect the data stored in a Smart Contract you can attach to a node geth attach http://<ip>:<port> and run:

loadScript('./scripts/contractInfo.js')
student = contractFactory.at(<contract_address>)
student.grades.call(0)
student.subjectsCompleted.call()
