Interoperability and Decentralisation: Part II


There are lots of new and exciting developments going on in the decentralized & self-sovereign world of MyData. After offering a general overview to standards and protocols in the morning Part I session, this Part II will focus on concrete projects that are already underway. We will explore examples where decentralized technologies are being used, how they help interoperability, and how they integrate with existing infrastructure.

Standards for a Self-Sovereign Technology Stack
Adrian Gropper

HIE of One Trustee® innovates in two aspects of personal data management: decentralized governance and a standards-based self-sovereign technology stack, using blockchain self-sovereign decentralized identifiers (DID), W3C Verifiable Credentials, and User Managed Access (UMA) authorization standards. Decentralized governance and self-sovereign tech are linked in the sense that governance groups compete for subjects that have a choice of governance group because the infrastructure is standardized. These concepts stand in contrast to first-generation personal information management that is typically not standards-based nor decentralized in governance.

Self-Sovereign Identity Meets Portable Data
Rouven Heck, Consensys and uPort

Blockchain based systems built on public ledgers like Ethereum enable entirely new ways for humanity to own, control and share their identity attributes, claims and any data associated with them. However, how can publicly accessible immutable ledgers be compatible with new data regulation like GDPR and the right to be forgotten? uPort is an open-source protocol that has been in development for over two years and is currently implemented in more than 10 decentralized applications (DApps), as well as in a live production use case in the City of Zug in Switzerland. With uPort, individuals can anchor their identity on a blockchain but retain all their data in a GDPR compliant way in an off-chain environment. Users and organisations can issue, sign data in a secure and interoperable way and selectively disclose it. All this happens via a mobile app. A secure, self-sovereign GDPR compliant identity at the tip of a fingertip. In our talk, we’d like to showcase the protocol’s architecture and perform a life demonstration.
