Web3 SAAS Data Labeling Platform

Overview

This project demonstrates the creation of a full-stack Web3 SAAS application. The application leverages Solana blockchain and Web3.js to build a data labeling platform where users can post data for labeling, typically by individuals in developing nations, and facilitate micro-payments using cryptocurrency.

Features

• Data Labeling Platform: Allows users to upload data that needs to be labeled and pays workers for labeling this data.
• Micro-payments with Solana: Utilizes the Solana blockchain for handling micro-payments efficiently and securely.
• AWS S3 Storage: Uses AWS S3 for storing user-uploaded images and generates pre-signed URLs for secure uploads.
• Full-Stack Implementation: Built with a Node.js and Express back-end and a React/Next.js front-end.
• Scalable and Secure: Designed to handle a large number of users and tasks while maintaining security and efficiency.

Technology Stack

• Front-end: React, Next.js
• Back-end: Node.js, Express
• Blockchain: Solana, Web3.js
• Storage: AWS S3

Key Components

1. Data Labeling Platform

A platform that connects users who need data labeled (e.g., images for machine learning models) with workers who can perform these tasks.

2. Micro-payments with Solana

The application uses the Solana blockchain to handle small payments to workers, ensuring quick and low-cost transactions.

3. AWS S3 for Storage

All user-uploaded data is securely stored in AWS S3. The application generates pre-signed URLs for uploading images to ensure that the back-end does not directly handle large files.

4. Front-end and Back-end

• Front-end: Built with React and Next.js, providing a responsive and dynamic user interface.
• Back-end: Implemented using Node.js and Express to handle API requests, user authentication, and interaction with the Solana blockchain.

Setup and Installation

1. Clone the Repository

   git clone https://github.com/zacharias1219/decentralized-fiver.git
   cd decentralized-fiver

2. Install Dependencies

   # Backend
   cd backend
   npm install
   
   # Frontend (User Front-end and Worker Front-end)
   cd ../user-frontend
   npm install
   cd ../worker-frontend
   npm install

3. Environment Variables Create a .env file in the backend directory and add your AWS and Solana credentials:

   AWS_ACCESS_KEY_ID=your_aws_access_key
   AWS_SECRET_ACCESS_KEY=your_aws_secret_key
   SOLANA_PRIVATE_KEY=your_solana_private_key

4. Run the Application

   # Start Backend
   cd backend
   npm start
   
   # Start User Frontend
   cd ../user-frontend
   npm run dev
   
   # Start Worker Frontend
   cd ../worker-frontend
   npm run dev

Usage

• User: Uploads data to be labeled and sets up tasks.
• Worker: Labels the data and receives micro-payments via Solana for each completed task.
