The full list of topics discussed between Markus and I in this podcast conversation include:

  • An overview of Decentralized Identifiers (DIDs) - how DIDs came about, their history and evolution.
  • The core properties of DIDs - what sets them apart from other types of identifiers.
  • DID Methods. As of this post, there are 160+ DID Methods listed in this registry. Are they all decentralized? Why are there so many? What are some popular ones that have been adopted?
  • What things to consider in your selection criteria for the right DID Method(s).
  • When would one use DIDs for abstraction purposes vs vanilla public-key cryptography?
  • DID Documents - what can be stored in them? How are they linked to a DID? What are some examples of things you can store in the authentication and service endpoints. How do you interact with them?
  • Using blockchain vs non-blockchain (e.g., DNS server) implementations for storing DID Documents. What are some key elements to take into consideration when looking at these different options?
  • Do DIDs disrupt or enhance existing certificate business models?
  • The power of DID Resolution - how has it evolved, how does it work? (see video below for a great explainer)
