Secure Blockchain-Based Voting System with Multi-Factor Authentication

In India, the current voting system mainly uses Electronic Voting Machines and requires people to go to polling booths, which takes a lot of time, manpower, and setup. It can also be difficult for people in remote areas, and there are still some concerns about how secure and transparent the system is. To improve this, our project introduces a blockchain-based voting system with multiple levels of authentication. In this system, a voter can vote online after verifying their identity using face recognition, fingerprint scanning, Aadhaar details, and a passkey. Once the vote is given, it gets stored in the blockchain and cannot be changed, which makes the system more secure. We used technologies like Ethereum, smart contracts, React, Node.js, Next.js, MetaMask, and Ganache to build the system. This reduces manual work and avoids issues like duplicate voting. The system is also faster and easier to use, which can help increase trust and participation in elections.
