Video : Introduction to Blockchain

Welcome to our exploration of blockchain technology! This introductory module will demystify the revolutionary technology that is poised to reshape our digital world.

We will begin by watching the video, "How does a blockchain work - Simply Explained." This video will provide you with a foundational understanding of what a blockchain is and how it functions. We will delve into the core concepts of blocks, hashes, and the innovative "proof of work" system that ensures the security and integrity of the chain.

By the end of this module, you will be able to:

• Define blockchain and explain its key components.

• Understand the role of hashing in creating a secure and immutable ledger.

• Describe how the "proof of work" mechanism prevents tampering.

• Explain the concept of a distributed ledger and the importance of consensus.

• Recognize the potential applications of blockchain technology beyond cryptocurrencies, such as in smart contracts, medical records, and more.

Let's begin our journey into the fascinating world of blockchain!
