A Blockchain Framework for Insurance Processes

摘要

We design a distributed platform with blockchain as a system service for supporting transaction execution in insurance processes. The insurance industry is heavily dependent on multiple processes between transacting parties for initiating, maintaining and closing diverse kind of policies. Transaction processing time, payment settlement time and security protection of the process execution are major concerns. Blockchain technology, originally conceived as an immutable distributed ledger for detecting double spending of cryptocurrencies, is now increasingly used in different FinTech systems to address productivity and security requirements. The application of blockchain in FinTech processing requires a deep understanding of the underlying business processes. It supports automated interactions between the blockchain and existing transaction systems through the notion of smart contracts. In this paper, we focus on the design of an efficient approach for processing insurance related transactions based on a blockchain-enabled platform. An experimental prototype is developed on Hyperledger fabric, an open source permissioned blockchain design framework. We discuss the main design requirements, corresponding design propositions, and encode various insurance processes as smart contracts. Extensive experiments were conducted to analyze performance of our framework and security of the proposed design.
