⚡ Decentralized P2P Energy Marketplace

A full-stack, enterprise-grade blockchain application built to facilitate peer-to-peer energy trading between prosumers and consumers using Hyperledger Fabric.

🏗️ Architecture

• Smart Contract (Brain): Written in Go. Handles ledger initialization, state queries, real-time energy/token trading, and administrative resource minting (Recharge).
• API Bridge (Backend): Written in Node.js (Express). Uses @hyperledger/fabric-gateway and gRPC to securely connect web requests to the blockchain's World State using X.509 cryptographic certificates.
• Frontend UI (Dashboard): Responsive HTML/JS dashboard that automatically queries the ledger for real-time balances and provides an immutable transaction history.

🚀 Features

1. Automated Trading: Smart contract rejects transactions if users have insufficient energy/tokens.
2. Immutable Ledger: Every trade is permanently recorded and cryptographically signed.
3. Admin Gateway: Allows authorized network administrators to mint energy/tokens to nodes.
4. Real-Time Sync: UI polls the blockchain directly, ensuring the displayed data is the absolute truth of the ledger.
