Project Video: Building Blockchain Projects 📚

Overview

  • Building Two Industry-Ready Projects: Supply Chain Management Smart Contract and Real World Crowdfunding.
  • Learning Objective: Master blockchain development from beginner to advanced level.
  • Project Goals: Develop complex smart contracts, understand fundamental smart contract concepts, and deploy decentralized applications (DApps).

Project 1: Decentralized Distributor System

  • Features:
    • Allows users to create, track, and manage product shipments.
    • Fully responsive for all devices.
  • User Interface:
    • Components include tables, service modules, and shipment tracking features.
    • Wallet connection for transaction management.
  • Functionality:
    • Users can create and start shipments, update statuses, and complete shipments.

Steps to Build the Decentralized Distributor System

  1. Connect Wallet:
    • Credentials required to connect to the wallet and display the wallet address.
  2. Create Shipment:
    • Provides recipient address, date, distance, and price.
    • Transactions managed via smart contracts.
  3. Start Shipment:
    • Update shipment status to in transit.
  4. Complete Shipment:
    • Mark shipment as delivered and record timestamps for delivery.
  5. Data Management and Retrieval:
    • Index-based data retrieval for shipment details.
    • Using indexes as unique IDs for each product in the marketplace.
  6. Responsive Design:
    • Ensure all features and components are fully responsive across devices.

Key Components

  • Tables: Display shipment data and statuses.
  • Forms: Input fields for creating and managing shipments.
  • Profile Section: User profile management and shipment history.
  • Service Modules: Shipment-related services and actions.
  • Tracking and Navigation: Enhanced user experience with easy tracking and navigation through shipments.

Tools and Frameworks

  • Next.js: Framework for building the application.
  • Tailwind CSS: For styling and responsive design.
  • Hardhat: For smart contract development and deployment.
  • Ethers.js: For interacting with smart contracts.
  • Web3 Modal: For wallet connectivity.

Project 2: Crowdfunding Platform

  • Features:
    • Users can create campaigns to raise funds for various projects.
    • Fully responsive design.
  • User Interface:
    • Comprehensive dashboard featuring campaigns, contributions, and user profiles.
    • Interaction with Ethereum wallets for transactions.
  • Functionality:
    • Create, manage, and contribute to crowdfunding campaigns.
    • Real-time updates and transaction management via smart contracts.

Steps to Build the Crowdfunding Platform

  1. Initialize Project:
    • Set up using Next.js and Hardhat.
  2. Smart Contract Development:
    • Develop crowdfunding smart contracts to handle campaign creation, fund management, and contributions.
  3. Frontend Development:
    • Use Tailwind CSS for styling and responsive design.
    • Create components such as navigation bars, footers, campaign cards, and forms.
  4. Wallet Integration:
    • Use Ethers.js and Web3 Modal for wallet connectivity.
  5. Deploy Contracts:
    • Deploy the developed smart contracts using Hardhat.
  6. Responsive Design and User Experience:
    • Ensure all components are fully responsive.
    • Provide smooth user experience for transactions and campaign management.

Key Components

  • Campaign Management: Create, modify, and manage fundraising campaigns.
  • Contribution System: Allow users to contribute funds to various campaigns.
  • User Profiles: Manage user profiles and track contributions.
  • Transaction History: Display history of contributions and campaign progress.

Tools and Frameworks

  • Next.js: Framework for building the application.
  • Tailwind CSS: For styling and responsive design.
  • Hardhat: For smart contract development and deployment.
  • Ethers.js: For interacting with smart contracts.
  • Web3 Modal: For wallet connectivity.

Setup and Configuration

  • Node and NPM: Ensure latest versions are installed.
  • Tailwind CSS Setup: Configure Tailwind CSS within the Next.js project for integrated styling.
  • Hardhat Setup: Install and configure Hardhat for smart contract development.
  • Environment Setup: Ensure development environment is equipped for blockchain development with the necessary tools and libraries.

Development Process

  1. Setup Project Structure:
    • Create directories for components, contexts, and smart contracts.
  2. Frontend Design:
    • Develop UI components like forms, tables, and navigation bars.
    • Ensure responsiveness with Tailwind CSS.
  3. Smart Contract Development:
    • Write and deploy smart contracts for managing shipments and crowdfunding campaigns.
  4. Context API for State Management:
    • Manage global state using Context API for seamless data flow between components.
  5. Deploy and Test:
    • Deploy smart contracts on local or test blockchain networks.
    • Thoroughly test the integration of smart contracts with the frontend.
  6. Final Integration and Deployment:
    • Integrate all components and ensure smooth operation.
    • Deploy the final application for production use.

Conclusion

  • Achieved Goals: Develop industry-ready blockchain applications with complex smart contracts and seamless user interfaces.
  • Learning Outcomes: Gained in-depth knowledge of blockchain development, smart contract interaction, and DApp deployment.
