"In this course, you'll learn the structure and properties of the blockchain itself and the individual blocks that make it up. You'll understand the blockchain features that provide security between different blockchain participants. You'll visualize different aspects of the blockchain and create and tamper with your own blocks through interactive simulations.
If you have some Python experience, you'll be able to build a small blockchain library in Python, including a Blockchain class and a Block class. Add functionality to add blocks, create hashes, and verify the chain."
