In this lesson, we’ll explore the ecosystems that support decentralized applications (dApps) and the programming languages that make them possible. From Ethereum to emerging platforms, each ecosystem brings unique features and advantages for developers. Additionally, we’ll dive into some popular programming languages—Solidity, Rust, and the newer Move language—each tailored to meet the demands of building secure, efficient dApps. By the end of this lesson, you’ll have an overview of the dApp landscape and the coding tools that power it.
