From UX to Justice: The Challenges of Designing On-chain Solutions for Authenticating Evidence of War Crimes


Daniel Park

Date of Talk


Jonathan Dotan​ is a Fellow at Stanford’s Center for Blockchain Research and the Stanford Compression Forum. He researches and lectures on the applied strategy and policy for a decentralized Internet and co-founded the Starling Initiative.

He has over 20 years of experience navigating the intersections of media, tech and policy. Jonathan recently wrapped six seasons writing and producing HBO’s Emmy Award-winning series, SILICON VALLEY. Previously, he worked in 30 countries on digital media adoption at the Motion Picture Association and began his career with a post at the United Nations Office of the High Representative for Bosnia and Hercegovina. He received an MPhil in International Relations from Oxford University, St. Antony’s College.

Daniel C. Park​ is a graduate student at the University of British Columbia researching blockchain and Distributed Ledger Technology applications in health data management and forensic image authentication.

He has experience conducting field research across Europe and Asia for the MasterCard Foundation and the G20 Research Group; providing regulatory consultancy for Virtual Asset Service Providers in the UK; and contributing to policy and blockchain projects at University College London, Hala Systems Inc., and NATO Association of Canada. He received his bachelor’s in International Relations at the University of Toronto, Trinity College, and currently serves as a naval reservist officer with the Royal Canadian Navy.


The Starling Framework for Data Integrity is a comprehensive set of tools and principles that empowers organizations to securely capture, store and verify human history.

Jointly developed by USC Shoah Foundation and Stanford University’s Department of Electrical Engineering, Starling is innovating with the latest cryptographic methods and decentralized web protocols to meet the technical and ethical challenges of establishing trust in our most sensitive digital records, such as the documentation of human rights violations, war crimes and testimony of genocide.

Starling represents a ground-breaking methodology that brings together immutable ledger and distributed storage technology, and human verification in the fight against the spread of misinformation and deep fakes. The suite comprises three modules: Capture, Store, and Verify; to provide an end-to-end chain of custody for photos, video, audio, and text, that can reduce information uncertainty in digital media.

While there is a lot of interest in the area of evidence-based decentralized attribution, surprisingly there are few working examples. That changed this summer. Over the last 90 days, UBC masters student Daniel Park worked with our collaborators at Hala Systems to build and deploy prototypes designed within the Starling framework to help their analysts document attacks against civilian infrastructure.

In this talk we’ll cover the lessons Daniel learned working alongside Hala Systems as we developed users to stories to user interfaces. We’ll then reflect on the path ahead for authenticated imagery, it’s evolving technical and ethical dimensions, and the various applications Starling could be applied to across humanitarian relief and accountability efforts.
