Tontine Game with Truffle and Drizzle

In the previous chapter, we learned a lot about the Ethereum ecosystem, but we are yet to realize the full potential of its different components. More precisely, we explored how Ethereum works, what a decentralized application (DApp) is and how to build one, and also covered the key concepts of Solidity and web3.js. We then introduced some of the most common smart contract design patterns (withdrawal from a contract, restricting access, state machines), before ending with a discussion of a contract’s cost optimization.

To brush up your knowledge and skills, in this chapter, we are going to build a Tontine DApp game. We will exploit this example to explore new tools that are going to change the way you ...
