For my purposes today, I want to construe "financial infrastructure" very broadly, to include not only the "hardware" components of that infrastructure--the physical systems on which market participants rely for the quick and accurate execution, clearing, and settlement of transactions--but also the associated "software, " including the statutory, regulatory, and contractual frameworks and the business practices that govern the actions and obligations of market participants on both sides of each transaction.
Realizing this potential will require partnerships between industry and government to develop a framework and best practices for cyber-physical-systems platform technologies that include integrated architectures, standards and protocols, advanced analytics, evaluation testbeds, and reference implementations to ensure such systems perform reliably, correctly, safely and securely.
