Architecture and implementation of a cross-ecosystem trust framework: Concepts & experiences

This talk, presented by Christoph Strnadl from Gaia-X AISBL, discusses the architecture and implementation of a cross-ecosystem trust framework, emphasizing the importance of establishing trust across diverse data ecosystems. It addresses the challenges of interoperability when different domains have their own rules and governance models, highlighting the necessity of a common trust foundation as data sharing expands among sectors. The speaker defines trust frameworks, which consist of legal rules, governance structures, and technical components, while also focusing on the automation of trust evaluation through software solutions, including compliance engines. Key insights include the introduction of a modular architecture that allows ecosystems to adhere to their own rules while leveraging shared standards and trust anchors, supported by practical implementation strategies using verifiable credentials and decentralized identifiers.
