[02:21] Measuring Adoption: When measuring adoption, should we start within specific geographical contexts or industries? What key performance indicators (KPIs) and signals should we consider? [08:30] Transitioning to Open Standards: We discuss the evolution of SSI adoption and how private-sector entities can shift towards using open standards and technologies. The role of public sector involvement in fostering adoption is also examined. [12:07] Communication Challenges: Communication plays a vital role in SSI adoption. We explore why it's challenging to communicate and market SSI compared to more straightforward technologies, like generative AI products. What are the unique hurdles in conveying the value of SSI? [18:24] Simplifying Terminology: The conversation continues with a focus on the use of technical jargon and terminology that can bewilder potential adopters. How can we transition from technical discussions to emphasizing business solutions? [23:17] Targeting Adopters: Is it more effective to target entities that serve as both issuers and verifiers or to focus on specific roles within the SSI ecosystem? What are the trade-offs? [27:56] Building Brand Recognition: Given the open nature of the SSI ecosystem, how can organizations build strong brand recognition, and what role do trust marks and certifications play? [31:47] Navigating Political Terminology: How do you address concerns surrounding the term "digital identity" being weaponized in political discourse when communicating about your SSI products? [37:44] Learning from European Adoption: What lessons can be learned from early adoption of digital identity programs in Europe, and how does it compare to the North American market? [47:29] UX Challenges: What are some of the key user experience (UX) challenges in the SSI space, and how can they be addressed to enhance usability and security? [50:59] Interoperability Impact: How does user experience impact interoperability in the SSI ecosystem, and vice versa? What collaborative efforts are needed? [53:22] Balancing Usability and Security: Balancing usability with security is a common challenge. How can the SSI community find the right equilibrium and enhance user adoption? Where to find Irene?

About Podcast Episode Read more about the episode by heading to ⁠⁠⁠⁠⁠https://northernblock.io/podcasts/exploring-commercial-data-ecosystems⁠⁠ The full list of topics discussed between Antti, Kai and I in this podcast conversation include: How do concepts of digital trust apply or differ in organizations versus individuals? How is trust achieved differently by organizations in organization-to-organization relationships versus organization-to-people relationships? Are data spaces a new type of role within this digital ecosystem? Can risk or liabilities be shared within these areas? Are there historical examples of organizations serving similar purposes for different ecosystems? Why is liability more important in this digital space, when the issuing authority or the party attesting to the authenticity of a document don't necessarily take liability if something goes wrong? How is liability managed in this open ecosystem space, particularly when interactions don't necessitate a legal relationship between parties? How can risk be managed to ensure enough rewards and shared risk that organizations will want to switch over and engage in the new model? Could consumers manage their possible vendors through a similar scenario by owning their own data, as suggested by Doc Searls's writings on vendor relationship management (VRM)? (Recommended book: https://www.amazon.com/Intention-Economy-When-Customers-Charge/dp/1422158527) Can the introduction of these digital ecosystems allow for earlier development of relationships in the customer acquisition cycle? How can these ecosystems enable trust-based marketing? How can new data ecosystems for commercial use cases be incubated and developed based on government digital identity or credentialing programs? What would be some recommendations for forming governance bodies for data ecosystems and the incentives for organizations to form and deploy services within these ecosystems? Where to find Antti?

Wenjing is a senior director of technology strategy at Futurewei leading initiatives focused on trust in the future of computing. His long career encompasses early Internet Routing development, optical Internet backbones, security operating system, Wi-Fi and 5G mobile networks, cloud native services and responsible artificial intelligence. He is a founding Steering Committee member of the Trust over IP Foundation. He contributed as the primary author of the Trust over IP Technology Architecture specification in which he articulated the layered approach to decompose the trust protocol stack and defined the core requirements of the trust spanning layer. Following that work, he is currently a co-Chair of the Trust Spanning Protocol task force  proposing the Inter-Trust Domain Protocol (ITDP) as the trust spanning protocol bridging different trust domains across the Internet. He is also a co-Chair of the AI and Metaverse task force currently drafting the white paper “Digital Trust in the Age of Generative AI”. Wenjing is a founding Board Member of the newly launched OpenWallet Foundation with a mission to enable a trusted digital future with interoperability for a wide range of wallet use cases and also serves in its Technical Advisory Council (TAC). He is a strong advocate of  human-centric digital trust as a foundation to responsible deployment of advanced artificial intelligence technologies. About Podcast Episode Read more about the episode by heading to ⁠⁠⁠⁠https://northernblock.io/podcasts/digital-trust-in-the-age-of-generative-ai/⁠ Some of the topics discussed between Wenjing and I in this podcast conversation include: Exponential Data Growth and AI Systems: Discussion centered around how the volume of data, particularly from AI systems like GPT-4, is exponentially increasing. As AI starts generating more content, this could create a feedback loop leading to astronomical levels of content. Interaction with LLM as Protocol: The question arose whether the pre-trained Language Model (LLM) could be equated to a protocol and if individuals might interact directly with the LLM in the future. Digital Identity and Trust in the Age of AI and Deepfakes: Concerns were discussed regarding the rise of AI and deepfakes, particularly their implications for digital identity and trust. The challenges of bi-directional authentication and the potential risk to content-based authentication methods were highlighted. Future of Digital Trust Protocols and Authentication: The potential of AI to generate content was related to the future of digital trust protocols. The necessity of digital signatures for authentication was suggested as a possible direction for the future. Reframing Identity: A broader understanding of identity was proposed, questioning whether a reframing of identity could influence our understanding of concepts like authentication. Trust in AI Bots vs. Humans: Personal observations on the level of trust in AI bots vs. humans were shared, suggesting a quicker formation of trust with bots. The implications for future human-bot relationships were considered. Potential Risks and Benefits of Technological Advancements: The discussion acknowledged both potential risks and substantial benefits of technological advancements. A greater level of trust in bots due to perceived lesser risk was noted, along with a significant move towards open source models in the digital trust space. Open-source Model for LLMs and Other Systems: The pros and cons of adopting an open-source model for Large Language Models (LLMs) and other complex systems were questioned. Where to find Wenjing?
