Steps to Set Up:

To build a DApp, you first need a smart contract that will serve as the backend logic. Let’s create a simple smart contract that allows users to store and retrieve a message on the blockchain.

The rise of blockchain technology has led to the development of decentralized applications (dApps), which operate on a peer-to-peer network rather than relying on centralized servers. dApps provide increased security, transparency, and resistance to censorship. In this tutorial, we'll walk through the process of building a dApp using Solidity, Ethereum, and IPFS. We’ll cover everything from writing smart contracts to deploying them on the Ethereum blockchain, and then integrating them with a front-end built with modern web technologies.

To start, ensure you have Node.js and npm installed on your machine. You can download them from the Node.js website.

Step 2: Connect to the Solana Network

Create a new file called index.js and add the following code to connect to the Solana blockchain:
