Summary

In this chapter, we introduced the concept of decentralization, which is the core service offered by blockchain technology. Although the concept of decentralization is not new, it has gained renewed significance in the world of the blockchain. Consequently, various applications based on a decentralized architecture have recently been introduced.

We began the chapter with an introduction to the concept of decentralization. Next, we discussed decentralization from the blockchain perspective. Moreover, we introduced you to ideas relating to the different layers of decentralization in the blockchain ecosystem and to the several new concepts and terms that have emerged with the advent of blockchain technology and decentralization from the blockchain perspective, including DAOs, DACs, and DApps. Finally, we looked at few examples of decentralized applications.

In the next chapter, we will see how Ethereum works and what we can develop using Ethereum. We will also see the important Ethereum clients and node implementations.
