Prerequisites

  • Install Python3.10 (and pip)

  • Install Ganache

  • Install Mosquitto Broker

    • Linux:

       $ sudo apt install -y mosquitto
 $ sudo systemctl start mosquitto

    • macOS:

        $ brew install mosquitto
  $ brew services start mosquitto

    • Windows: visit mosquitto.org

  • Set virtual environment

    • Linux/macOS:

       $ python3.10 -m venv venv
 $ source venv/bin/activate

    • Windows:

       $ py -3.10 -m venv venv
 $ .\venv\Scripts\activate

  • Install Requirements

    $ pip3 install -r requirements.txt

  • Django Migrations

    $ cd django_website
$ python manage.py makemigrations core
$ python manage.py migrate

  • Blockchain

     # Change directory:
 $ cd blockchain/

 # Compile Solidity:
 $ python compile_contract.py

 # Deploy compiled contract:
 $ python deploy.py

 # Run event handler:
 $ python event_handler.py

    • Test event handler by adding data blockchain

       $ python add_sensor_data.py

      Should you see the event message and its data, then blockchain has been successfully set up.

Run

  • Run Mosquitto Broker service on localhost:1883

  • Run Ganache on localhost:7545

  • In Terminal

    1. Run django server: $ python manage.py runserver

    2. Run blockchain/event_handler.py (pushes notification to django from blockchain)

    3. Run blockchain/subscriber.py (subscribes to broker)

    4. Run blockchain/publisher.py (publishes to broker)

  • Now you should have a data flow!
