Blockchain is a disruptive and emerging technology that is still poorly understood. This course will explain what blockchain is, and how tokenization can be used in cryptocurrencies as well as other practical applications. These applications include stablecoins (like Facebook's Libra and JP Morgan's JPMCoin), machine-to-machine payments, identity protection and supply chain management (Walmart Maersk, IBM), secure vote, distributed exchanges and decentralized finance. Property transfers, central bank fiat crypto (e.g. Fedcoin or China's digital Renminbi), dispensing prescribed drugs, private records and intellectual property. Financial reporting and media and advertising are just a few. This course aims to provide an in-depth understanding of blockchain technologies, (ii), identify the business situations where blockchain technology could be used to solve critical problems, (iii), select the blockchain technology with the greatest chance of success for that particular problem, and (iv). Describe the risks associated with this new technology.
