1. Abstract
Blockchain-Based E-Voting is a secure electronic voting system designed to conduct elections using blockchain technology and smart contracts. It records votes as tamper-evident transactions, helping prevent unauthorized modifications and improve transparency. Eligible voters can log in, cast their votes digitally, and verify that their votes have been recorded. Smart contracts automate vote counting and help prevent duplicate voting. The system aims to improve election accessibility, accountability, and the integrity of voting records.
2. Objectives
- To develop a secure electronic voting platform.
- To prevent duplicate voting.
- To maintain transparent and tamper-evident voting records.
- To automate vote counting using smart contracts.
- To provide voter authentication and access control.
- To display election results accurately.
3. Existing System
Traditional voting systems use paper ballots or centralized electronic voting platforms. These systems may require manual counting, extensive administration, and centralized record management.
Disadvantages:
- Time-consuming vote counting.
- Risk of human error during counting.
- Possibility of unauthorized record modifications.
- Limited transparency in vote tracking.
- High administrative costs for some election processes.
4. Proposed System
The proposed system uses blockchain technology and smart contracts to manage digital elections. Administrators register eligible voters and candidates, while authenticated voters cast their votes through a web application. Smart contracts enforce voting rules and record votes on the blockchain. The system counts votes and displays results after the election closes.
Key Features:
- Admin and voter dashboards.
- Voter authentication.
- Candidate registration.
- One-vote-per-eligible-voter enforcement.
- Blockchain-based vote recording.
- Automated vote counting.
- Election result dashboard.
5. Implementation Procedure
- Requirement Analysis: Identify election rules and user requirements.
- Frontend Development: Create the interface using HTML, CSS, JavaScript, or React.js.
- Backend Development: Build APIs using Python Flask or Node.js.
- Blockchain Setup: Configure Ethereum or a local Hardhat network.
- Smart Contract Development: Write Solidity contracts for election creation, voting rules, and vote counting.
- Voter Registration: Register eligible voters and verify their identities.
- Candidate Registration: Allow administrators to add candidates.
- Voting Process: Enable authenticated voters to cast one vote per election.
- Result Generation: Count votes and display results after voting closes.
- Testing: Test duplicate voting, unauthorized access, vote integrity, and election closure.
