1.1 Why Blockchain? - Video Tutorials & Practice Problems

What was the last time you bought a brand name item, like a luxury watch, or maybe a pair of sunglasses? How can you tell that that watch or those glasses was actually genuine and not a counterfeit knockoff? Or how about, let's assume that you wanna make an investment in a multi-million dollar painting or a work of art of some sort. How can you tell that that painting or that work of art was actually made by the real artist and that it's not just a knockoff or that it wasn't stolen? Being able to have accurate information about the provenance and the history of an asset when you're dealing in transaction of value is essential, but in a world full of hackers and malware and counterfeit goods, it's becoming increasingly difficult to prove the authenticity and the provenance of those assets. There's an answer, and it's blockchain, because blockchain could provide a single source of truth that's permanent, verifiable, and unchangeable. And that is what we will be talking about in this course.
