From open banking to global healthcare data exchange, we are entering the era of Radical Interoperability. The mandate is clear: data must move to create value. But as we tear down silos, we find ourselves living in a "Glass House" - where every new API connection and trust relationship increases the risk of a privacy catastrophe. How do we design systems that are "Open by Default" but "Private by Design"?

This session explores the architectural paradox at the heart of modern identity. Using public standards like Verifiable Credentials (VCs) and Selective Disclosure, we examine the industry shift from "sharing data" to "sharing proof." Learn how to build decentralized trust registries that enable radical collaboration without centralizing risk. In 2026, trust will not be earned by who has the most data, but by who exposes the least.
