This application was delivered as a final piece of coursework for my masters in computer science. The application is a Decentralised application and can be deployed to either a test or production blockchain.

This application stores data on public blockchain and also a private datastore (BigchainDB) Some basics to orientate yourself....

1. The main app is written in NodeJS. Once you have pulled the project first rung

    npm install

This will load the project dependencies.

2. If running locally you will then need to setup and install a local version of BigchainDB:

https://www.bigchaindb.com/ - Documentation here. BigchainDB will run on top of MongoDB. Please make sure this is installed already in your local environment.

3. Setup a local version of a Blockchain. The easiest way to do this is via Ganache:

https://www.trufflesuite.com/ganache

4. Ensure you have version of Python3 available on your local machine. The application uses a Python loader to load data into the application.

5. Setup Metamask in a browser. Documentation here: https://metamask.io/

6. Install Make on the local environment https://mg.readthedocs.io/make_tutorial/make_tutorial.html

• 1. Start the BigchainDB server
• 2. Cd the project directory and run

• 3. Start ganache and ensure that it is running on this setting:

     host: "localhost",
     port: 7545,

• 4. Run this command

npm install

If you have not already done so. This will install all dependencies for the project.

• 5. Run this command

make load_reset

This will load a set of test data to access when using the app.

• 7. Run this command

truffle migrate --reset

This will deploy the contract to Ganache

• 8. Start the server

npm run dev

You should now be good to go and test out the application running locally on your own enviroment!

Enjoy!
