A blockchain-based service composition architecture in cloud manufacturing

ABSTRACTCloud manufacturing is a promising rising paradigm in which geographically distributed manufacturing resources are exposed as services in the cloud platform. The task of cloud manufacturing is to provide manufacturing resources as services to fulfil users’ demands. However, in existing cloud manufacturing architecture all the information is possessed by the platform operator, and the management of manufacturing services is highly centralised. It is firmly believed that decentralisation and elevating information transparency can help increase the operational performance. Blockchain is such a technology that distributes transactions information to a peer-to-peer network such that information is fully shared and unchangeable by partial peers. This paper proposes a blockchain-based cloud manufacturing architecture to enhance information transparency and decentralisation. The proposed platform is responsible for exposing manufacturing resources and wrapping them as services. Manufacturing services can ...
