Summary

Let’s summarize what we learned in this chapter. We started by understanding blockchain as a technology and framework. Then, we saw how cryptography plays a very important and integral part in the blockchain technology stack. We also covered some of the basic components of a blockchain. We looked at the anatomy of a blockchain transaction and how it plays an important role, followed by a few common types of blockchain and how they are used. This chapter also laid out the foundation to get started with Web3 and the core fundamentals required for Web3.

In the next chapter, we’ll start looking at the Ethereum blockchain to understand its core fundamentals and basics. We’ll look into concepts such as Ethereum Improvement Proposals (EIP) and Ethereum Request For Comment (ERCs) and the importance of key management. We’ll also learn how to use a wallet and deep-dive into the history of Ethereum.
