Uchaguzi - Decentralized Voting Platform

Project Overview

Uchaguzi (Swahili for "choice" or "election") is a cutting-edge decentralized voting platform built on Ethereum that revolutionizes community governance through advanced blockchain technology. This project represents a comprehensive implementation of democratic decision-making systems with enterprise-grade security, transparency, and user experience.

Technical Architecture

Core Technology Stack

• Blockchain: Ethereum (Sepolia Testnet + Local Hardhat)

• Frontend: Next.js 14 with TypeScript and Tailwind CSS

• Smart Contracts: Solidity with Hardhat framework

• Web3 Integration: Wagmi v2 + RainbowKit for wallet connectivity

• State Management: React hooks with custom voting state management

• Security: ReentrancyGuard, input validation, and audit trails

Smart Contract Features

// Advanced governance with multiple phases

enum Phase { Registration, Voting, Execution, Closed }

// Weighted voting system

struct VoterInfo {

    bool registered;

    uint256 weight;

    address delegatee;

    bool hasVoted;

    uint256 votedProposalId;

}

// Rich proposal metadata

struct Proposal {

    string description;

    address proposer;

    uint256 voteCount;

    bool executed;

    uint256 createdAt;

}
