Transparenchan

Overview

Transparenchan is a decentralized application (DApp) built on the Ethereum blockchain to enhance transparency, security, and trust in digital transactions. This project leverages smart contracts to ensure immutable and verifiable records of interactions.

The application features a client-server architecture, where users can interact with the blockchain through a React.js frontend and a Node.js backend. It also supports Metamask wallet integration for seamless blockchain transactions.

Features

✅ Blockchain-Powered Transparency – Transactions and records are immutable and publicly verifiable.
✅ Decentralized Storage – Eliminates intermediaries and ensures trustless execution of smart contracts.
✅ Secure Smart Contracts – Uses Solidity for tamper-proof transaction logic.
✅ Client-Server Integration – Smooth interaction between frontend, backend, and Ethereum network.
✅ User Authentication – Secure login and identity verification through blockchain.
✅ Testing Framework – Implements Mocha & Chai for rigorous smart contract testing.
