This course addresses the blockchain and the associated legal and regulatory considerations. Topics include cryptocurrencies (particularly bitcoin), Ethereum, smart contracts, and registries of ownership of digital goods. The course will also consider the evolving legal and regulatory aspects of blockchain technologies at the state and federal levels as well as in selected non-US jurisdictions. No previous technical experience is needed for taking this course. That said, students in the course should be willing to study and discuss not only the legal and regulatory aspects of the blockchain but also some of the key technological underpinnings, as that will help to enable a broader and more holistic understanding of this important technology.
