This course examines how financial services are being rebuilt around digital platforms, shared ledgers, and automated decisions. It covers blockchain technology, Bitcoin and Ethereum, decentralized finance, tokenized real-world assets, stablecoins and central bank digital currencies, followed by payment systems, digital lending and crowdfunding, robo-advising, cybersecurity, and regulatory technology. For each topic the course separates what the technology does, what problem it solves, how the business earns money, what risks it creates, and who is accountable under which regulation, with Chinese Mainland and Hong Kong policy covered alongside international comparisons. Designed for beginners, it is taught through mechanisms and cases rather than technical detail and does not require programming. Students work in teams on a venture proposal and a company case.
