Decentralized Voting Smart Contract
Tamper-proof blockchain voting protocol with Hardhat & Solidity access controls
Problem & Challenge
Overview & Purpose A blockchain-based voting application designed to demonstrate secure, transparent, and tamper-proof elections through Ethereum smart contracts. The system ensures that each eligible voter can vote only once while maintaining immutable vote records on-chain. Solution & Impact The project showcases how decentralized technologies can eliminate centralized manipulation by enabling transparent vote recording, automated result calculation, and verifiable election processes through blockchain.
Architecture & Solution
Smart contract protocol enforcing strict cryptographic authorization to guarantee single-vote election security and public auditability.
