In a previous post, we dissected  NIST’s white paper on Blockchain for Access Control Systems (NIST IR 8403) (1).  Both projects offer a great overview of the promise of blockchain technologies at the physical device layer and opportunities for the creative development of an innovative marketplace for novel defensive cybersecurity platforms. We will now take a look at the IEEE P2958 standard, which the World Wide Web Consortium (W3C) announced in July 2022 has been recommended as an official web standard:  Decentralized Identifiers (DIDs) v1.0:  “This new type of verifiable identifier, which does not require a centralized registry, will enable both individuals and organizations to take greater control of their online information and relationships while also providing greater security and privacy.”
