paschmann/blockchain_origin repository overview

⁠Introduction

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.

⁠Concept

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.

⁠Architecture

The application has 3 main components.

1. A web UI used to create and view the blockchain, peers on the network and create transactions.
2. A HTTP API used to accept calls from the web UI and interact with the blockchain
3. 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.

⁠Installation

Download/clone this repo

• Run npm install in the root directory to install dependencies

I would suggest opening at least 3 terminal/command windows:

• Run npm run start:manufacturing in one window
• Run npm run start:distribution in another window
• Run npm run start:retail in 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.

⁠Reference

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.

⁠Requirements

Node.js
