Blockchain-Based Secure Voting System for Transparent Digital Elections in India

Abstract

A widespread mistrust toward traditional voting systems in India has made digital transformation in elections increasingly crucial. Existing digital systems often lack transparency, scalability, and security, leading to voter disengagement. This paper proposes a blockchain-based voting system tailored to Indian elections. The framework ensures voter privacy, decentralization, and verifiable results using cryptographic techniques, smart contracts, and a decentralized app (dApp). The proposed system eliminates the need for physical polling stations, simplifies vote validation, and prevents tampering or fraud. It supports flexible consensus algorithms to improve performance and avoid 51% attacks. This paper discusses system architecture, layered design, implementation methodology, and the potential of blockchain to transform Indian elections.

Introduction

Summary: Blockchain-Based Voting System for India

India’s traditional election process is complex, costly, and prone to human error and vote tampering—even with Electronic Voting Machines (EVMs). To address these issues and improve transparency, the paper proposes a blockchain-based voting platform tailored for India.

Key Features of the Proposed System:

1. Voter Verification: Via Aadhaar or mobile OTP.

2. Vote Coin (VC): A unique token issued to each verified voter.

3. dApp Interface: Voters interact through a decentralized mobile/web application.

4. Smart Contracts: Validate voter identity and vote integrity.

5. Blockchain Ledger: Records immutable, encrypted votes.

6. Miner Nodes: Validate transactions and maintain consensus.

System Architecture (Five Layers):

1. Interface Layer – Voter interaction through mobile/web dApps.

2. Application Layer – Handles authentication and smart contracts.

3. Trust Layer – Manages consensus mechanisms.

4. Blockchain Layer – Stores encrypted vote data.

5. Security Layer – Ensures resistance to attacks (e.g., 51% attack).

Workflow:

• Voter registers and gets verified.

• Receives one Vote Coin.

• Casts a vote through the dApp.

• Vote is validated, hashed, and added to the blockchain.

• Voter receives a transaction hash; their Vote Coin is consumed.

Security Measures:

• Cryptographic hashing and digital signatures secure vote data.

• Immutable ledger prevents tampering.

• Smart contracts enforce vote rules.

• Custom algorithm inspects each block for integrity.

Consensus Algorithms:

• Supports PoW, PoS, and PoA, switchable based on election size and load.

• Prevents 51% attack by monitoring miner hash rates.

Implementation Strategy:

• Pilot projects in college or local elections.

• Uses Ethereum-based smart contracts and multilingual dApp.

• Real-time result monitoring via admin dashboards.

Performance Results:

• Response time: < 2 seconds

• High transaction throughput and low latency

• Near-zero risk of vote duplication or tampering

• Reduces manual intervention and enhances voter trust

Conclusion

This paper presented a blockchain-based voting system tailored for India. It enhances transparency, scalability, and voter trust. With blockchain\'s immutability and smart contracts, the system removes the need for physical polling and middlemen. Pilot implementations and awareness campaigns can help adopt this technology for national elections.
