We need a broader debate on the sustainability of blockchain

Abstract

Alexander Rieger is a postdoctoral researcher at the Interdisciplinary Centre for Security, Reliability and Trust (SnT) at the University of Luxembourg. His research interests include innovative digital technologies such as blockchain, decentralized digital identities, and artificial intelligence. Alex leads the scientific advisory team for the FLORA blockchain project of Germany's Federal Office for Migration and Refugees and acts as advisor to the European Blockchain Partnership and various public and private sector partners in Germany and Luxembourg. Tamara Roth is a postdoctoral researcher at the Interdisciplinary Centre for Security, Reliability and Trust (SnT) at the University of Luxembourg. Her research interests include the interplay of innovative technologies such as blockchain and decentralized digital identities with sociocultural and socioethical constructs in public administration and healthcare. Moreover, she investigates technology adoption and implications of technologies for sustainable development from a psychological and neurobiological perspective. Johannes Sedlmeir is a researcher on information systems at the FIM Research Center, University of Bayreuth. In his research, he focuses on the energy consumption and performance benchmarking of different blockchains, the application of cryptographic methods such as zero-knowledge proofs for scalable and privacy-oriented blockchain solutions in different sectors, and decentralized digital identities. He received his M.Sc. in theoretical and mathematical physics. Gilbert Fridgen is professor and PayPal-FNR PEARL chair in digital financial services at the Interdisciplinary Centre for Security, Reliability and Trust (SnT) at the University of Luxembourg. In his research, he analyzes the transformative effects of digital technologies on individual organizations and on the relationship between organizations. He addresses potentially disruptive technologies like blockchain, decentralized digital identities, artificial intelligence, or the Internet of Things. His research involves information systems engineering and IT strategy and (risk) management, as well as regulatory compliance. In his projects and partnerships, he collaborates with partners in financial services, energy, mobility, manufacturing, and consulting, as well as with public bodies and governments.
