Blockchain Applications in Multiple Domains: Current Status, Challenges and Prospects

Abstract

Blockchain has been broadly practiced in different markets. It is decentralized, unchangeable, and transparent. Our essay summarizes its practices in three key industries including finance, healthcare, as well as supply chain management. In the former, it benefits efficiency in payment and settlement, preventing greenwashing and optimizing carbon trading. In the middle, it helps in digital health check management, clinical trial transparency, and insurance claim simplification. Blockchain also brings product traceability and multi-party collaboration, while facilitating managing flow. Our work uncovered the common obstacles blockchain practices confronted. Future direction standing on newest research heats and multi-subjects are identified. Hopefully, we can plant theoretical bases and practical guidance in blockchain's coming development and general practices.
