Notes Storage DApp

A decentralized application (dApp) built using Ethereum blockchain technology. This project utilizes Truffle for smart contract management, React for the frontend, and Bootstrap for styling.

---

Features

• Store, retrieve, edit, and delete notes securely on the blockchain.
• Connects to Ethereum wallet (e.g., MetaMask) for account management.
• Responsive and user-friendly interface built with Bootstrap.

---

Prerequisites

Ensure the following are installed on your system:

• Node.js (v16 or above recommended)
• npm or Yarn
• Truffle Suite
• MetaMask browser extension
• Ganache (for local blockchain testing)

---

Folder Structure

• frontend/: Contains the React application for the user interface.
• truffle-setup/: Contains the Truffle project for smart contract development.

Installation and Setup

Setting Up the Truffle Project

1. Navigate to the Truffle Setup Folder

   cd truffle-setup

2. Compile Smart Contracts

   truffle compile

3. Deploy Smart Contracts

   • Start Ganache and note the RPC server URL (usually http://127.0.0.1:7545).
   • Deploy the contracts:

     truffle migrate --network development

Setting Up the Frontend

1. Navigate to the Frontend Folder

   cd ../frontend

2. Install Dependencies

   npm install

3. Update contractInfo.js as per your deployed contract [truffle-setup/build/contracts/NotesStorage.json].

   export const CONTRACT_ABI = []; // Your contract ABI here
   
   export const CONTRACT_ADDRESS = ""; // Your contract address here
   

4. Start the Development Server

   npm start

Smart Contract Interaction

• Smart contracts are written in Solidity and located in the truffle-setup/contracts/ folder.
• To test the contracts:

  cd truffle-setup
  truffle test

---

Technologies Used

• Truffle: Development framework for Ethereum.
• React: Frontend JavaScript library.
• Bootstrap: CSS framework for styling.
