Anonymous Voting System with zk-SNARKs

The Anonymous Voting System leverages zk-SNARKs (Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge) to create a secure, private, and efficient blockchain-based voting mechanism. It aims to solve issues of traditional voting methods, such as high costs and lack of transparency, by enabling anonymous and tamper-proof voting.

Overview

This project provides a decentralized voting system where voters can participate anonymously using zero-knowledge proofs. It ensures the following:

• Privacy: Voter identities and their choices remain confidential.
• Security: Votes are verified and tamper-proof, leveraging blockchain immutability.
• Transparency: Results are publicly verifiable without revealing individual votes.

How It Works

1. Voter Registration: A list of eligible voters is created and managed by the system.
2. Ticket Generation: A unique, single-use voting ticket is generated for each voter using a zero-knowledge proof.
3. Voting: The voter uses the ticket to cast a vote, which is verified on the blockchain.
4. Verification: The vote is validated using zk-SNARKs to ensure the voter is eligible and the ticket hasn’t been reused.
5. Result Compilation: The votes are aggregated, and the final results are available for public verification.

Key Features

• One-Time Tickets: Tickets are cryptographically bound to the voter list and validated using zk-SNARKs.
• Zero-Knowledge Proofs: Ensures that only eligible voters participate while maintaining complete anonymity.
• Blockchain Integration: Provides a transparent and immutable record of the voting process.

Project Structure

• Client Side: Handles the user interface for generating tickets and submitting votes.
• Server Side: Manages voter registration, ticket validation, and vote tallying.
• Blockchain: Stores the vote data and ensures integrity through smart contracts.

Running the Project

1. Install Dependencies: Follow the setup instructions to install all necessary tools and libraries.
2. Setup the Environment: Initialize the project and configure any blockchain or cryptographic dependencies.
3. Run the System:
   • Start the polling system.
   • Generate and download voting tickets.
   • Cast votes and verify results.
