Blockchain-based Toll Payment System

Overview

This project implements a decentralized toll payment system using blockchain technology. The system enhances traditional toll collection processes by providing transparency, security, and efficiency through the use of blockchain and QR codes.

Features

• Blockchain Integration: Utilizes a distributed ledger for transparent and tamper-proof toll transactions.
• Smart Contracts: Implements smart contracts for automatic toll deduction and validation.
• QR Code Payments: Users can make toll payments by scanning QR codes at toll booths.
• Decentralization: Reduces the need for centralized toll collection infrastructure, minimizing points of failure.
• Secure and Private: Ensures secure and private transactions using blockchain cryptography.

How it Works

1. User Registration: Users register on the blockchain network to create a digital wallet.
2. Wallet Funding: Users fund their digital wallets with cryptocurrency.
3. QR Code Generation: Toll booths generate unique QR codes for each transaction.
4. Payment Process: Users scan the QR code using a mobile app, triggering an automatic payment through a smart contract.
5. Blockchain Confirmation: The transaction is recorded on the blockchain for transparency and accountability.
6. Toll Gate Activation: Upon successful payment, the toll gate opens automatically.

Getting Started

Prerequisites

• Next.js
• Remix IDE
• Ethereum wallet (Metamask)
• Ethereum-compatible blockchain network (Sepolia Testnet)

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/blockchain-toll-payment.git

2. Install dependencies:

   cd blockchain-toll-payment
   npm install

3. Deploy smart contracts:

   truffle migrate

(you can also deploy smart contracts manually using remix ide)

4. Run the application:

   npm start
   npm run dev
