Each of these use cases can be built on the same principles you learned in this tutorial but with more complex logic and integrations.
In this tutorial, we covered the basics of building a decentralized application (DApp) with smart contracts on the Ethereum blockchain. You learned how to set up a development environment, write and deploy a smart contract, and create a front-end interface to interact with it. This DApp is just the beginning—there's much more to explore in the world of decentralized applications, from scaling solutions to integrating with off-chain data sources.
