Blockchain – Principles and Practices

Visit Tutorial Page ( Report)

Blockchains are probably one of the most highly talked about technologies at the moment as they provide a way to attain digital trust on the Internet. There is so much emphasis on the technology that companies are very keen to learn about Blockchains and adopt them. Venture capitalists are currently diverting a lot of investments into funding Blockchain-based companies. In this course, Blockchain - Principles and Practices, you will explore the fundamental data structures and algorithms used to build a typical Blockchain and build up a working example over the course. First, you will learn how to store single transactions in a block. Second, you will discover how to store multiple transactions in a block using Merkle trees. Next, you will be taught how to make the Blockchain tamper-proof using mining and proof-of-work. Finally, you will learn how nodes on a Blockchain maintain consensus. By the end of this course, you will have the knowledge and tools necessary to build your own Blockchain.

this course was completely useful for me and I really enjoyed that. the demo parts at first looks frightening but the instructor explain them very well and they help you to understand the concepts.
