The document discusses reinventing insurance for a blockchain economy. It argues that while insurance is essential for distributing risk, current large insurance companies may not survive in a blockchain economy due to issues like high costs, misaligned incentives, and poor customer experience. As an alternative, the document proposes building insurance on blockchain networks, which could make the process more automated, standardized, transparent, and fair through the use of smart contracts. It provides the example of flight delay insurance and outlines goals for developing a decentralized insurance platform in the coming years to enable this new vision of insurance.
