Reaching this chapter is a notable accomplishment in your Ethereum learning trip, during which you've thoroughly learned how to write smart contracts with Solidity, and how to build a complete DApp using web3.js and Drizzle. We focused, in the last two chapters, on building a decentralized web application on Ethereum using a set of tools, such as Remix or Truffle. In this walkthrough, we will learn how to harness a powerful language, such as Java, to build an Ethereum desktop or mobile application. Along the way, we will discover new concepts in Solidity, such as calling third-party APIs in your smart contracts or libraries.
As we learn by example in this book, we will break into finance and build a financial project that manages a futures smart contract using Java (SE). Throughout this interesting use case, we will go over the following points...
