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

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.
