Decentralized Storage IPFS

Abstract

1. Introduction

A simple DApp to upload a document to IPFS and then store the IPFS hash on the Ethereum blockchain. Once the IPFS hash number is sent to the Ethereum blockchain, the user will receive a transaction hash. We will use Create-React-App framework to make a front-end. This Dapp works with any user that has MetaMask installed in their browser.

2. Objective

This is a decentralized IPFS/File storage system that connects to the blockchain via web3 and requires a crypto payment fee to add your Decentralized file to the system.

This project demonstrates how JavaScript can be applied to a real-world Blockchain & Cloud Computing problem.

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

1. Why does this problem need a blockchain or cloud-native design?
2. Explain the smart contract / infrastructure components and how they interact.
3. How are gas costs or cloud costs kept under control?
4. How is the system secured (keys, IAM, access control)?
5. How would the solution scale to many more users?
