Overview of this book

Ethereum and Blockchain will change the way software is built for business transactions. Most industries have been looking to leverage these new technologies to gain efficiencies and create new business models and opportunities. The Ethereum Cookbook covers various solutions such as setting up Ethereum, writing smart contracts, and creating tokens, among others. You’ll learn about the security vulnerabilities, along with other protocols of Ethereum. Once you have understood the basics, you’ll move on to exploring various design decisions and tips to make your application scalable and secure. In addition to this, you’ll work with various Ethereum packages such as Truffle, Web3, and Ganache. By the end of this book, you’ll have comprehensively grasped the Ethereum principles and ecosystem.

Creating upgradable smart contracts

Once a smart contract is deployed in the Ethereum network, its code cannot be changed at any point. State values can be modified if this was allowed in the original code. This brings the great advantage of immutability and trust, but with a cost. The addition of a new feature, or even a bug fix, cannot be performed due to the design of Ethereum.

In this recipe, we will focus on designing and creating upgradable smart contracts that can help maintain the application better.

Getting ready...

You need to have a working Ethereum installation for deploying and testing the smart contract. You can also use the Remix IDE to write and test the Solidity code.

It is required to have good knowledge...
