Decentralized E-Voting System with Biometric Hash Authentication Using Ethereum Smart Contracts
Tamper-proof academic and municipal voting platform built on Ethereum, Solidity, Metamask, and SHA-256 voter hashing.
Problem Statement
Conventional electronic voting machines and paper ballots face recurring allegations of tampering, lack of cryptographic voter privacy, and centralized database manipulation.
Proposed Solution
An immutable decentralized voting dApp deployed on an EVM blockchain testnet where votes are cryptographically cast via smart contracts, preventing double-voting and enabling public mathematical auditability with zero identity leakage.
Key System Features
