Abstract - The digital era continually reshapes how democratic processes are conducted. Traditional and electronic voting systems, though pivotal in shaping democratic outcomes, often grapple with concerns about security, transparency, and accessibility. This research paper introducesanovelblockchain-basedvotingsystemdesignedto addressthesecriticalvulnerabilities.UtilizingtheMERNstack (MongoDB, Express.js, React.js, Node.js), Ganache for simulating a local blockchain environment, and Web3.js for interactions with the blockchain, this system leverages the inherent security, immutability, and transparency properties of blockchain technology. Our proposed system promises to revolutionize the voting process by ensuring that every vote cast is not only secure but also verifiable and transparent. It eliminates reliance on central authorities, reducing risks of tampering and fraud, and facilitates a user-friendly platform that is accessible to a broad user base. The development approach is detailed, involving rigorous testing phases that ensure the system's reliability and security before full-scale deployment. By enabling a tamper-proof and transparent ledger of recorded votes, the system enhances voter trust and engagement, potentially increasing turnout andthe integrity ofelectoralprocessesglobally.Thispaperaimstocontributeto the discourse on technology's role in enhancing democratic processes by offering a scalable, secure, and transparent methodofvoting,pavingthewayforfutureinnovationsinthe domain of digital democracy

What is a Voting System?
A voting system encompasses the methods and processes usedtocollect,count,andvalidatevotesduringanelection. Ideally, a voting system must be accessible, transparent, secure,andcapableofaccuratelyreflectingtheintentionsof voters.Itshouldensureconfidentiality,provideaverifiable audittrail,and prevent unauthorized actions such as vote tamperingorduplication.
1.1 Traditional Voting Systems and Their Limitations
Traditional voting systems typically involve paper ballots or mechanical devices that voters use torecord their votes. These votes are then manually countedand verifiedbyelectionofficials.Whilethismethodhas been the standard for centuries, it is fraught with challenges. Paper-based systems are vulnerable to human error during the countingprocessandlogisticalissuessuchasthe distribution,storage,anddisposalofballots.Theyarealso susceptibletotamperingandfraud,includingballotstuffing andthedestructionofballots.Moreover,manualprocesses aretime-consumingandcostly,requiringsignificanthuman resourcesandlogisticalplanning.

decentralized digital ledger thatrecords all transactions across a network of computers. This ledger is secure and transparent; transactions can be verified by all participants and cannot be altered once recorded. A blockchain-based voting system utilizes this technologyto createanimmutableandtransparentrecordofvotes. Each vote is recorded as a transaction on the blockchain, which provides a verifiable audit trailthatenhancesvoter confidenceandsystemintegrity.
