The rise of blockchain technology enables a fully automated decentralised autonomous risk transfer. In this Lecture, you will not only learn about the functionality as well as operating principles of this new method of risk transfer. You will also get an overview of the corresponding institutional arrangement and its challenges. At least two major challenges can be identified: Ensuring the quality of the product and attaining a critical network size. A feasible solution for these problems is the usage of system-specific tokens, which are used as a form of digital collateralization. How these theoretical concepts can be translated into practice will be explained while demonstrating the economic potential of the idea. While flight delay risk is already handled through decentralised autonomous risk transfer, the biggest benefits can be realised by decentralising crop and hurricane insurance, including a seamless transfer of the risk to capital markets.
