Building Your First Ethereum Apps
IN THIS CHAPTER
Exploring your development environment
Coding in Solidity
Writing smart contracts
Using blockchain data
The best way to understand how to write apps for the Ethereum blockchain is to start writing them. You can read about all the components and language syntax, but until you write some code, it won’t sink in. You’ve already gone through the steps to set up your development environment, so why not start using it?
Don’t worry about writing code before you know what you’re doing — here, you’ll start with small, simple Solidity apps. (Remember that Solidity is the most popular language for developing dApps for the Ethereum blockchain.) And you’ll find out about syntax and process as you need to. The typos you enter and other issues you encounter will help you get the hang of it more quickly.
The code we show you in this chapter is really simple. That’s okay. You’re going to find out how to write code in Solidity, and you’re going to start from the very beginning. Whether you’re new to programming or you already know several ...
