In May of 2022, The National Institute of Standards and Technologies (NIST) released a white paper with a promising perspective on the role of blockchain at the OSI physical layer by way of access control systems. Meanwhile, The Institute of Electrical and Electronics Engineers (IEEE) Identity of Things Working Group has been working with a global consortium on the development of the IEEE P2958 standards. These projects offer a great overview of the promise of blockchain technologies at the physical device layer and opportunities for the creative development of an innovation marketplace for novel defensive cybersecurity platforms.  We review the NIST and IEEE efforts here in two separate posts. We begin with the NIST white paper.
