Keywords: Secure Digital Voting, Blockchain Technology, Transparency, Decentralized I. INTRODUCTION The ability to vote is one of the fundamental rights of any democratic society. Voting is a process through which citizens elect their representatives and participate in the decision-making process of their country. However, traditional voting systems have several issues, including fraud, hacking, and manipulation. These issues undermine the credibility of the election results and can damage the trust of citizens in the democratic process. Blockchain technology has emerged as a potential solution to these issues. Blockchain technology offers decentralized, immutable, and transparent systems that can provide secure and trustworthy digital voting experiences. This paper presents a secured digital voting system using blockchain technology. We discuss the design and implementation of the system, its features, and its potential advantages over traditional voting systems. We also discuss the challenges and limitations of using blockchain technology for voting systems. A. Design and Implementation Our proposed secured digital voting system using blockchain technology has several components, including a user interface, a blockchain network, and a smart contract. The user interface is the platform through which voters can cast their votes. The blockchain network is the decentralized infrastructure that ensures the integrity and security of the voting process. The smart contract is the program that executes the rules and regulations of the voting system. The system works as follows: Voters register for the election by providing their details and proof of identity. Once their identity is verified, voters are given a unique identifier that is recorded on the blockchain. This identifier ensures that each voter can only vote once. On the day of the election, voters log in to the user interface and cast their votes. The votes are encrypted using a public key encryption algorithm and sent to the blockchain network. Once the votes are recorded on the blockchain, they cannot be altered or deleted, ensuring the integrity of the voting process. The smart contract executes the rules and regulations of the voting system, including verifying the identity of voters, ensuring that each voter can only vote once, and tallying the votes. Once the voting period is over, the smart contract calculates the results of the election and publishes them on the blockchain. © IJRASET: All Rights are Reserved | SJ Impact Factor 7.538 | ISRA Journal Impact Factor 7.894 | 5401 International Journal for Research in Applied Science & Engineering Technology (IJRASET) ISSN: 2321-9653; IC Value: 45.98; SJ Impact Factor: 7.538 Volume 11 Issue V May 2023- Available at www.ijraset.com B. Features Our secured digital voting system using blockchain technology has several features that make it secure, transparent, and trustworthy.
