Cloud manufacturing service transaction information recording system and method based on block chain

Abstract

The invention relates to a cloud manufacturing service transaction information recording system and method based on a block chain. The system comprises a plurality of book keeping nodes; a plurality of book keeping nodes are communicated with each other to form a recording node network; each book keeping node comprises a book keeping information database, a transaction block chain database, a book keeping permission competition module, a transaction information abstract generation module, a transaction block chain generation module and a transaction block chain updating module; the method is applied to the recording node network; recording node network comprises a plurality of book keeping nodes communicated with each other; each book keeping node contests for book keeping permissions in different book keeping periods in a competing mode; and the method comprises a transaction information recording process and a transaction information inquiry verification process. Compared with the prior art, according to the cloud manufacturing service transaction information recording system and method disclosed by the invention, a data recording method and a data structure in the cloud manufacturing service transaction process are improved, and non-repudiation and inquiry verification of transaction can be conveniently implemented.

Description

technical field [0001] The present invention relates to a transaction information recording method, in particular to a blockchain-based cloud manufacturing service transaction information recording system and method. Background technique [0002] With the concept of "manufacturing as a service", cloud manufacturing abstracts the manufacturing resources and manufacturing capabilities of enterprises into cloud services—manufacturing services. Enterprises provide various manufacturing services to provide services to customers in need. Cloud manufacturing provides an effective solution for manufacturing resource sharing. [0003] Cloud manufacturing is generally realized through a cloud manufacturing platform. At present, typical domestic cloud manufacturing platforms such as Tianzhi.com and so on. Service-providing companies (cloud manufacturing service providers) and service-needing companies (cloud manufacturing service demanders) access the platform through the Internet, s...
