BlockVote is a digital voting system that removes the need for physical ballots or trusting third-party voting platforms. Instead, it uses blockchain technology to make voting:
- Completely transparent (no manipulation)
- Secure (every vote is verified and logged immutably)
- Accessible (voters can vote online with Aadhaar + Metamask)
This system helps ensure that elections are fair, fraud-free, and openly auditable, without compromising voter privacy.
BlockVote is built as a full-stack decentralized application (dApp) where:
- Voters register using their Aadhaar number and wallet
- All transactions (voter registration, candidate addition, votes) are recorded via smart contracts on Ethereum
- Admins manage election phases and candidates via metamask-authenticated actions
- Results are generated in real time from the blockchain
The system ensures end-to-end security, role-based access, and decentralized trust.
