Invenger

🧠

Built to explore the fusion of traditional backend logic with decentralized technologies.

Project Overview

Invenger is a decentralized inventory management application that seamlessly integrates Java-based services with the Ethereum blockchain.

Developed secure data handling with IPFS.
Architected for efficient blockchain transaction processing.
Decentralized yet performant.

Tools Used

Technology	Purpose
Java	Core backend logic and services
JavaFX	GUI interface for inventory operations
Ethereum	Smart contract deployment and interaction
Hardhat	Local Ethereum testing environment
IPFS	Decentralized file storage

Code Snippet

public void storeToIPFS(String data) {
  IPFS ipfs = new IPFS("/ip4/127.0.0.1/tcp/5001");
  NamedStreamable.ByteArrayWrapper file = new NamedStreamable.ByteArrayWrapper(data.getBytes());
  MerkleNode addResult = ipfs.add(file).get(0);
  System.out.println("Stored at hash: " + addResult.hash);
}
