When you finish, you will understand Chromia's core features and have the skills to build your own decentralized applications. ## What will I learn? The course covers the fundamentals you need as a base for decentralized app development: 1. **Database model and simple queries**: You design the database model for the news feed app and write basic queries that fetch and display data. 2. **Input verification**: You validate and secure user input to close off potential vulnerabilities. 3. **Accounts**: You manage user accounts in the app, including registration and authentication. 4. **Project structure**: You learn how to organize the project, lay out the codebase, and handle dependencies. 5. **Frontend integration (React app)**: You connect the backend to a React frontend to give the news feed app a complete user interface. ## What will be built? You work on both the frontend and the backend of a real-time decentralized news feed app. This hands-on project gives you the skills to build decentralized applications and a starting point for exploring blockchain technology. The app is built on Chromia. ## Repository link The full source code for the course is available in the [news feed course repository](https://bitbucket.org/chromawallet/news-course). ### Related materials The course draws on the following documentation.
