In this guide, we have explored the process of building a health DApp on the Celo network using Solidity, React, and web3.js. The DApp allows users to store their health data securely on the Celo blockchain, track their symptoms and vital signs, and receive personalized health recommendations based on their data. We have covered the key steps involved in building a health DApp, from setting up the development environment to deploying the smart contract to the Celo network. We have also provided sample code and screenshots to help developers follow along with the tutorial. By building a health DApp on the Celo network, developers can help empower users to take control of their health data and make more informed decisions about their health.
