About Podcast Episode

Digital Trust Infrastructure is quickly becoming essential from an economic, political and security standpoint.

Much of the infrastructure today is controlled and owned by device OS providers such as Apple and Google.

It’s crucial that digital trust infrastructure providers can compete with the device OS providers.

To produce a level playing field, we must have open standards and open access to the infrastructure. This applies to both to Governments and Private Sector digital trust providers.

Some of the key topics covered during this episode with Drummond are:

  • Wallets vs Agents – their differences, their relationship and how agents will use more and more contextual intelligence to help you make decisions according to your preferences.
  • Can non-OS digital trust infrastructure providers compete with the device OS providers? (e.g., Apple owns the OS for mobile/desktops/tablets/smart watches)
  • Comparing DIDComm to NFC – if NFC really facilitates security and trust for close distance, do the combinations of digital wallets, digital agents and protocols (like DIDComm) do the same for trust at distance?
  • Trust Spanning Protocol – establishing authentic connections where both parties can authenticate each other (using the same hourglass model as TCP/IP). What are the architectural requirements for this protocol? And how can various protocols (e.g., DIDComm, KERI) converge into a trust spanning protocol?
  • What does DIDComm do better/different than other data exchange protocols? (such as OAuth2 and OpenID Connect)
  • Can the Trust over IP stack be used outside of Identity use cases? (e.g., payments, data sharing, social media)
  • Comparing SSI to Email – similarities in protocol design, asynchronous or synchronous UX, simplicity and generality.
