Learn the core concepts of cryptocurrency and its underlying Blockchain technology by implementing it in JavaScriptAbout This VideoYou'll learn the practical applications of Blockchain by building a functional widget application from scratch.By the end, you'll not only have a fantastic understanding of Blockchain technology, but you'll also know how to exactly utilize Blockchain and build applications with it.You'll also have access to resource files and you can even add the app we build in this course to your resume, which means you'll already start off with an app!In DetailIt's the perfect time to start learning Blockchain technology, and we've got the perfect course to help you master it! Originally designed by Satoshi Nakamoto for his Bitcoins, Blockchain has evolved to become something much bigger. It is no longer limited to implementations in cryptocurrencies, but instead is spreading its reach into other segments as well such as database, finance, IoT, and so on.So, what exactly is Blockchain? The term Blockchain refers to a list of records that constantly grow when more information is added to it. These blocks (chains of information) are linked and secured using cryptography.So, if you like to stay ahead of the technology boom and get your hands on the next best thing, this course is made just for you!
