A naive simplified implementation of using blockchain as a static register in a food origin scenario allowing manufactures, distributers and retailers to publish product information and view the data.
This project was developed as a Proof of concept for a paper entitled "Blockchain and the transformation of Marketing". The general premise behind the paper was around how companies can utilize digital ledgers on blockchain for product tracability and reduce the risks or impact of food fraud or food safety incidents.
The application has 3 main components.
- A web UI used to create and view the blockchain, peers on the network and create transactions.
- A HTTP API used to accept calls from the web UI and interact with the blockchain
- A peer-to-peer network used for syncronization of peers on the blockchain network
Note: Blockchain data is not persisted, when all 3 of the server components are stopped, data is cleared.
Download/clone this repo
npm installin the root directory to install dependencies
I would suggest opening at least 3 terminal/command windows:
npm run start:manufacturingin one window
npm run start:distributionin another window
npm run start:retailin another window
This will run 3 different nodes simulating the peer-to-peer network
Open your browser to http://localhost:3001 once the server is running to view the Admin panel where you create transactions directly on each of the nodes.
The blockchain component of this project is largely based on Naivechain from Ihartikk. I took the implementation and refactored and rewrote the codebase in ES5 which matches the frontend and other components.
