📋 Problem Statement

Problem Statement ID: 25045

Problem Statement Title: Blockchain-Based Supply Chain Transparency for Agricultural Produce

Description

Create a blockchain-based system to track agricultural produce from farm to consumer, ensuring transparency in pricing, quality, and origin. The solution should allow stakeholders (farmers, distributors, retailers) to verify transactions and reduce exploitation in the supply chain.

Expected Outcome

A decentralized platform with a user-friendly interface for farmers and consumers to trace produce, reducing fraud and ensuring fair pricing, deployable on low-cost hardware or cloud infrastructure.

Technical Feasibility

Leverages existing blockchain frameworks like Ethereum or Hyperledger, with smart contracts for automated tracking and QR code integration for consumer access.

🚀 Getting Started

Prerequisites

Before you begin, ensure you have the following installed:

• Node.js (v18 or higher)
• Bun (for backend) - Install Bun
• PNPM (for frontend) - Install PNPM
• PostgreSQL (v14 or higher)
• Git

Installation

1. Clone the Repository

git clone https://github.com/idityaGE/sih-project.git
cd sih-project

2. Setup Backend

# Navigate to backend directory
cd backend

# Install dependencies
bun install

# Copy environment variables
cp .env.example .env

# Configure your .env file with:
# - Database connection URL
# - JWT secrets
# - Blockchain RPC URLs
# - Private keys (for development only)

3. Setup Database

# Start local development database
bun run db:dev

# Run database migrations
bunx prisma migrate dev --name init

# Open Prisma Studio (optional - database GUI)
bun run db:studio

4. Setup Blockchain

# Start local Ethereum node (in a new terminal)
anvil

# Deploy smart contracts (in another terminal)
cd ../blockchain
forge build
forge script script/Deploy.s.sol --rpc-url http://localhost:8545 --broadcast

5. Start Backend Server

cd ../backend
bun run dev

The backend server will start on http://localhost:8080

6. Setup Frontend

# Navigate to frontend directory
cd ../frontend

# Install dependencies
pnpm install

# Copy environment variables
cp .env.example .env.local

# Configure your .env.local with:
# NEXT_PUBLIC_API_URL=http://localhost:8080

7. Start Frontend Development Server

pnpm dev

The frontend will start on http://localhost:3000
