Abstract - The Trust Vote is a blockchain-based digital
With the rapid growth of digital systems, many organizations have started adopting online voting platforms. Although these systems improve speed and convenience, most of them still rely on centralized databases that can be manipulated, hacked, or controlled by a single authority. This creates a major risk of data breaches, insider attacks, and system failure. Hence, there is a strong need for a secure, transparent, and verifiable voting mechanism that can ensure trust and integrity.
voting system designed to provide secure, transparent, and tamper-proof elections for organizations such as universities, companies, and institutions. Traditional voting systems, including paper-based and centralized electronic platforms, often suffer from issues like vote manipulation, lack of transparency, unauthorized access, and delayed result generation. To overcome these limitations, the proposed system leverages blockchain technology and smart contracts to ensure integrity, decentralization, and automated election workflows. In this system, voters are authenticated using OTPbased verification to ensure only eligible users can participate. Each vote is encrypted, digitally signed, and recorded as an immutable blockchain transaction, preventing tampering and double voting. Smart contracts automate critical election operations such as voter validation, vote recording, and realtime vote tallying without manual intervention. The decentralized nature of blockchain removes the risk of a single point of failure and enables authorized stakeholders to audit election records securely while preserving voter anonymity. Trust Vote supports remote voting through a user-friendly web interface, improving accessibility and voter participation. The system reduces operational costs, minimizes human errors, and ensures fast and accurate result declaration. By combining blockchain security, cryptographic mechanisms, and automated smart contract execution, Trust Vote provides a reliable and modern solution for conducting trustworthy digital elections.
Blockchain technology has emerged as a powerful solution for such problems. Blockchain provides decentralization, immutability, transparency, and cryptographic security. It stores records in a distributed ledger where data cannot be altered once written. These features make blockchain highly suitable for secure voting applications. By integrating smart contracts, voting rules can be automated, ensuring that elections are conducted without human intervention and preventing illegal voting practices such as double voting. Trust Vote is proposed as a blockchain-based e-voting system for organizational elections. It ensures strong voter authentication using OTP verification, encrypted vote recording, automated vote counting, and transparent auditability. The system enables secure remote voting through a web interface and provides real-time result generation. This project aims to deliver a modern, reliable, and tamper-proof voting platform that improves voter confidence and reduces administrative overhead.
1.1 Background of Digital Voting
KEYWORDS : Blockchain, E-Voting System, Smart Contracts, OTP Authentication, Secure Voting, Transparency, Vote Integrity, Decentralization, Digital Signature, Tamper-Proof Elections.
Digital voting systems were introduced to reduce the manual workload of elections and to provide faster vote counting. Many modern organizations use online voting systems to improve efficiency and accessibility. However, most existing digital voting solutions depend on centralized architectures where a single database stores all voter and election data. This central control creates vulnerabilities such as unauthorized modifications, cyber-attacks, and data loss due to system failure [1]. Therefore, traditional digital voting systems require stronger security and transparency mechanisms.
1. INTRODUCTION Voting is one of the most important decision-making processes in any democratic or organizational environment. It allows individuals to select leaders, approve proposals, and express collective opinions. However, traditional voting systems such as paper ballots and centralized electronic voting platforms often face serious issues like vote tampering, impersonation, delayed counting, and lack of transparency. These challenges reduce trust in the election process and create doubts about the fairness and accuracy of results.
