Leveraging blockchain based decentralized apps for the Tokyo Olympics amid the COVID-19 pandemic: A value-focused thinking based assessment and ideation

摘要

The COVID-19 pandemic has induced a cloud of uncertainty over the mega sports event, the 2021 Tokyo Olympics. Cancelling or re-scheduling the event could have serious repercussions on the economic, social and environmental well-being for the involved stakeholders. Thus, it becomes critical to conduct events of this magnitude by adopting appropriate public health measures. In this research, we primarily focus on two main premises relative to public health and safety, contact tracing and crowd management. We explore and evaluate the usability of blockchain based decentralized apps in crowd management and contact tracing for the Tokyo Olympics using value-focused thinking (VFT). A VFT framework aids in narrowing fundamental and strategic objectives that need to be addressed for smooth contact tracing and crowd management by understanding stakeholder viewpoints. We established an equivalence of the objectives identified through VFT with blockchain technology properties. Further, we also present a conceptual ideation of contact tracing and crowd management through blockchain based decentralized apps for the Tokyo Olympics. This work could potentially assist decision-makers, researchers and stakeholders involved in organizing the Tokyo Olympics in understanding and analysing the utility of blockchain based decentralized apps for crowd management and contact tracing.
