The Center for Digital Finance and Technologies at Columbia University's School of Engineering and Applied Sciences focuses on addressing the needs of Fintech companies and exploring emerging financial innovations. The current economic system faces challenges related to efficiency, accessibility, and transparency. Affordable financing options are lacking for individuals and businesses, and the cost of transferring funds or securities is high. Trading assets also incur significant expenses. The operations of banks and wealth managers need full transparency for both clients and regulators. Access to financial services is restricted, leaving a considerable portion of the global population needing banking services.
