Join us as we bring together researchers across disciplines to explore decentralized protocols and digital infrastructures.

Decentral protocols and infrastructures are core to the current strive for European sovereignty and infrastructural resilience. Ongoing innovations target domains like finance, digital identity and credentials, data ecosystems, business transactions, social media.

However, both development and research of such open protocols are often domain specific and also distributed across theoretical computer science, information systems, human computer interaction and software engineering, addressing individual aspects of such infrastructures.

This workshop aims to bring together relevant research across subdisciplines of computer science and neighboring disciplines in order to identify common challenges, and discuss technical, conceptual and methodological approaches to address them.
