Blockchain Projects: ERC-721 & Hyperledger Fabric

Welcome! This repository showcases two major blockchain projects completed for the CSE 598: Engineering Blockchain Applications course:

1. ERC-721 Token Project – Deployed on Polygon Mumbai Testnet (Ethereum-compatible)
2. Hyperledger Fabric Private Blockchain Project – Chaincode for a Supply Chain scenario

1. ERC721-Token-Project

• Objective: Create and deploy an ERC-721 (NFT) smart contract on the Polygon Mumbai Testnet.
• Tech Stack:
  • Solidity
  • Remix IDE
  • MetaMask browser extension
  • Polygon Mumbai Testnet
• For detailed instructions, see ERC721-Token-Project/README.md.

2. Hyperledger-Fabric-Project

• Objective: Develop chaincode in Go for a private blockchain scenario with Hyperledger Fabric.
• Features:
  • Supply chain management (creating products, updating, transferring ownership)
  • Demonstrates ledger read/write, transaction proposals, etc.
• Tech Stack:
  • Hyperledger Fabric
  • Go language for chaincode
  • Docker + Docker Compose
• For detailed instructions, see Hyperledger-Fabric-Project/README.md.
