Summary

In this chapter, we've learned a great deal of things related the mechanisms that integrate blockchain technology with real-world scenarios, such as exchanges and adoption rates. You are now capable of using powerful tools to improve the quality of your decentralized applications and smart contracts, while also being able to predict future price movements based on the most important metrics about Ethereum. In the first section, you saw how the Ethereum blockchain is defined using a specific set of rules known as the chain spec, then you learned about the different parts that make such impressive technology possible, including the many applications built on each layer. Finally, you saw how Ethereum consensus, economics, and metrics work to help you understand why Ethereum is such a valuable coin, while also seeing the way many nodes cooperate toward a singular objective using what's known as consensus.

In the next chapter, we'll cover different implementations of the Ethereum protocol to become capable of exploiting the full potential of Ethereum in your own projects.
