Furthermore, we presented various definitions of blockchain from different point of views. We also introduced you to few applications of blockchain technology. Next, we explored different types of blockchain. Finally, we examined the benefits and limitations of this new technology. Few topics such as blockchain scalability and adaptability issues were intentionally introduced only briefly, as these will be discussed in depth, in later chapters.
