Minilateralism’s author, Professor Chris Brummer, has authored a new guide for students and experts alike that are seeking to learn about, or deepen their understanding of, fintech law. Technology is redefining financial services―including the way actors make and settle payments, raise capital, extend loans, and memorialize increasingly complex relationships. At the same time, new innovations―from cryptocurrencies to marketplace lending, robo-advising, and mobile payments―are creating novel regulatory issues for anti-money laundering requirements and cybersecurity. Professor Brummer’s Nutshell provides an overview of some the key developments reshaping finance―and the rules deployed to oversee them.
