Blockchain-Based AI Model Marketplace

Assignment 4 - Blockchain Technologies 1

Overview

This project is a blockchain-based AI Model Marketplace where users can buy and sell AI models using an ERC-20 token. It integrates functionalities developed in previous assignments, including an ERC-20 smart contract and an AI model marketplace, into a single product. Now, users are provided with possibility of purchasing AI models and even listing their own on our platform using our very own token - EATKN.

Features

1. User Authentication and Wallet Integration

• Implemented wallet connection using Metamask or similar tools.
• Users can connect their wallets to interact with the marketplace.

2. Token Balance Display

• Displays the user's ERC-20 token balance on the marketplace interface.
• Provides functionality to refresh the token balance.

3. AI Model Listings

• Shows a list of AI models available for purchase with details such as:
  • Model name
  • Description
  • Price in ERC-20 tokens
  • Seller details (wallet address)
• Allows sellers to create new listings by providing:
  • Model details
  • Price in ERC-20 tokens
  • Upload model file or access link (secure storage implemented)

4. Purchase Flow

• Buyers can view AI model details.
• Purchase process includes:
  • Transferring the required amount of ERC-20 tokens to the seller.
  • Updating the marketplace UI to reflect the sale (e.g., marking models as sold or adjusting inventory).

Technologies Used

• Blockchain: Ethereum
• Smart Contracts: Solidity (ERC-20 Token + AIModelMarketplace contract)
• Wallet Integration: Metamask
• Frontend: html, css, js
• Backend: Node.js, Web3js
• Deployment: thirdweb.com
