| Knowledge is the crystallization of human wisdom and culture,and it is the product of social development.With the passage of time,science and technology change with each passing day.The birth of the Internet promotes the dissemination and knowledge sharing,accelerates the updating and replacement of knowledge.The value of knowledge can be deeply explored by modern technology.In the era of knowledge economy,knowledge exchange and knowledge sharing among enterprises in manufacturing supply chain become more abundant,and the influence of enterprise knowledge sharing on enterprise performance is more and more significant.In the process of knowledge sharing by the network communication,the Internet development assumes the demand of knowledge dissemination in the manufacturing supply chain,and facilitates the knowledge sharing process and brings benefits to the social development.On the other hand,in the open network environment,it may cause the infringement of intellectual property of others and restrain the knowledge creation.How to accelerate the dissemination of knowledge and realize the knowledge sharing on the basis of protecting the rights and interests of knowledge creators is a practical significance subject.At present,blockchain and smart contract technology have been widely used and popularized,providing support for knowledge sharing in the manufacturing supply chain.With the technical support of decentralized blockchain,knowledge sharing among manufacturing enterprises promotes information exchange among enterprises,and increases resource sharing,and forms a complete knowledge sharing mechanism.This thesis will study the mechanism of using these two technologies which accelerate the dissemination of knowledge realize the sharing of knowledge and protect the rights and interests of knowledge creators.The research contents of this thesis are described as follows:(1)The storage structure of the blockchain is utilized to uniquely identify the metadata of the shared knowledge by the timestamp and the digital signature.The storage structure containing the unique identity is applied to the blockchain to achieve the release of the shared knowledge.The authenticity of the shared knowledge is verified.(2)By using the sharing mechanism of smart contract,the knowledge sharing request and service model based on smart contract is proposed.The third-party supervision is removed,and the knowledge security of both parties is realized.At the same time,a supervision mechanism is put forward to ensure the maximization of benefits in the process of knowledge sharing.(3)By means of combination of blockchain and smart contract technologies,the construction of sharing platform on tool knowledge in the manufacturing industry is realized.On this platform,users can log in,and query tool knowledge,and tool knowledge sharing and other related operations.Through verification,the method studied of this thesis can realize the security performance in the knowledge sharing process of manufacturing supply chain. |
