      • Title: Decentralization and Delft Blockchain Solutions

      • Abstract: blockchain is one of the most attractive topics in recent years, not only for the cryptocurrency needs of the world but also for the possibility of sharing data and performing automated business logic among mutually untrusted stakeholders. At the Delft University of Technology, decentralization and distributed trust have been investigated in many aspects such as systems, security, privacy, ethics, and economic elements, more than a decade now. In this talk, I will focus on blockchain solutions in supply chain and finance and address privacy and security challenges for future research.
