## ⚙️ Overview
**MediChain** is a secure, transparent, and efficient blockchain-based system that transforms pharmaceutical supply chain management. Built on Ethereum, this solution provides end-to-end traceability of medical products from manufacturers to patients, eliminating counterfeit drugs and ensuring patient safety.
---
## ✨ Features
- 🔒 **Secure Drug Registration**: Immutable blockchain ledger for manufacturers
- 🔁 **Automated Ownership Transfer**: Smart contract-based secure handovers
- 🧭 **State Management**: Track medicine journey from production to sale
- 📱 **QR Code Verification**: Instant authentication with a simple scan
- 🏛️ **Decentralized Architecture**: No single point of failure
- ⏱️ **Real-Time Tracking**: Monitor the movement of medicines live
---
## 🛠️ Tech Stack
- **Blockchain**: Ethereum (Private Network), Solidity
- **Frontend**: HTML, CSS, JavaScript
- **Web3 Integration**: MetaMask, Web3.js
- **Smart Contracts IDE**: Remix IDE
---
## 🏗️ System Architecture
MediChain consists of three integrated layers:
### 1️⃣ Blockchain Network
- Private Ethereum blockchain as the foundational database
- Solidity smart contracts for business logic automation
- Immutable record-keeping with timestamped transactions
### 2️⃣ Client Communication Layer
- Web3.js for blockchain connectivity
- User interfaces for stakeholder interactions
- MetaMask integration for secure authentication and transaction signing
### 3️⃣ Application Layer
- HTML-CSS-JavaScript frontend interface
- QR code integration for product verification
- Real-time tracking dashboard
---
## 🧩 Key Modules
### 🔗 Smart Contract Operations
Smart contracts written in Solidity handle:
- `addMedicine()` – Register medicines with full traceability
- `purchaseMedicine()` – Buy securely with automatic ownership transfer
- `updateMedicineState()` – Update lifecycle state (e.g., Manufactured, In Stock, Sold, Expired)
- `getMedicine()`, `getMedicineState()` – Retrieve real-time product and status info
### 🖥️ Dashboard
- Clean, professional interface modeled after modern commerce platforms
- Track:
- 🧾 Order history
- 💊 Total drugs registered
- 📦 Total stock across batches
- 🏷️ Total units sold
- Manufacturer insights, quantity analytics, and QR-based lookup tools
### 🔍 Track Medicine
- Search by medicine ID to view:
- 🧬 Batch metadata
- 🏭 Manufacturer identity
- ⏳ Lifecycle state and timestamps
- 👤 Current owner in the supply chain
- One-click **Verification Report** generation for regulators or consumers
### 🛒 Buy Medicine
- 🔎 Live search and filter system
- 💳 Detailed product cards with dynamic pricing
- ✅ Integrated blockchain validation before purchase
- ⚡ Smooth transaction flow with MetaMask authentication
### 👥 User Management
- Register as:
- 🏭 Manufacturer
- 🚚 Distributor
- 🏪 Pharmacy
- Role-based login with Ethereum identity
- All interactions are cryptographically signed
