About Podcast Episode

In the previous podcast episode that Drummond and I recorded together in October, 2022, we touched upon the hourglass design model for digital trust applications, which was just about to be proposed as a new Technology Architecture Specification by the Trust over IP Foundation (ToIP).

The hourglass model is perhaps the most widely recognized hallmark of the Internet protocol suite. The single “spanning layer” at the “waist” of the hourglass is the IPv4 protocol. Much of the success of the Internet is attributed to this “hourglass” design in which the spanning layer protocol maximizes interoperability by providing a common way for all the higher level layers to communicate with all the lower levels. For those interested, I discussed how this relates to digital trust in more detail here.

Since we recorded that last podcast, I’ve spent time carefully reading through Kim Cameron’s 2005 whitepaper entitled “The Laws of Identity” (PDF version). I found it to be one of the most well written, and concise papers about (1) the impacts of not having trusted digital identities on the internet; and (2) seven laws to follow when designing digital identity systems if one wishes for it to be successful on the open internet.

It was interesting to then start visualizing how this ToIP hourglass model could start to embody the seven laws defined in Kim’s paper, which still resonates today, some 17 years after its publishing.

In this podcast episode with Drummond Reed, we discuss,

  • Does the new ToIP Technology Architecture Specification address the questions posed by Kim Cameron in his 2005 whitepaper?
  • If we agree that one identity system cannot rule them all, how then can an identity metasystem solve interoperability across identities, identity systems and contexts? (hint: a trust spanning protocol!)
  • What are the leading contenders for becoming the trust spanning protocol?
  • What are some examples of trust tasks, other than credential exchange, that are possible to unlock?
  • How does a trust spanning protocol x trust tasks lead to advancements in how we manage our relationships, and help us move away from phone numbers and emails as our most valuable identifiers?
  • Where can governments participate within the hourglass model framework to accelerate digital trust on the open internet?
