Research on Data Platform Construction and Security of Information Network Based on Blockchain Technology

The idea of blockchain is introduced, and the security of computer network is studied. Its main goal is to enhance the confidentiality and privacy of the data transfer and sharing process in the network. This project intends to convert the generated contract into a network-based expression of block coding and block information fusion, and combine this information expression with the security of computer networks to form an information security intelligent contract. This paper presents the process of identity authentication in network-based information system. Demand aggregation and buffering are used to reduce the amount of redundant communication in the network and speed up the transmission of communication. The use of off-chain storage can not only reduce the storage burden on the blockchain, but also ensure the safety and security of the data. The experimental simulation verifies that the trust distribution method based on blockchain and attribute can effectively control the access to data, and provide users with more secure and reliable information sharing and publishing services.
