Supply-Chain-Management-using-Blockchain-Technology

A full-stack decentralized supply chain management system using Solidity, Node.js, MongoDB, and React. It enables seamless tracking of medicines through various stages from manufacturing to retail with participant roles like Supplier, Manufacturer, Distributor, and Retailer.

Smart Contract Features

Written in Solidity, the smart contract allows:

1. Adding Medicines
2. Registering Participants
3. Assigning participants to medicines
4. Tracking stages: Ordered → Raw Material Supplied → Manufactured → Distributed → Retail → Sold
5. Getting current medicine stage
6. Shipment creation and medicine transfer logging

Tech Stack

1. Frontend: React + Vite + Tailwind CSS
2. Backend: Node.js + Express + Web3.js
3. Database: MongoDB with Mongoose
4. Blockchain: Solidity Smart Contract (Truffle / Ganache)
