In this course, you will be introduced to the exciting world of Blockchain technology, which is the backbone of cryptocurrencies. With this innovative technology, clients in the network can come to a consensus without relying on trust.

Today, various blockchains are in operation, some using the energy-intensive Proof-of-Work model and others using the more efficient Proof-of-Stake method to validate transactions and maintain network security.

This course will provide a brief history of blockchains, delving into the technical aspects of how they function and the differences between the Proof-of-Work and Proof-of-Stake consensus algorithms. You will learn about the fundamental components of a blockchain, including blocks, nodes, and mining. We will also discuss decentralization and its role in ensuring the transparency and security of the network.

In addition, the course will cover the different types of blockchains such as public, private, and consortium blockchains, and the various use cases for each. You will also be introduced to the current challenges in the blockchain industry and potential solutions.

Finally, we will examine the future of blockchain technology and its potential to transform various industries.
