Network Information Technology Application Based on Blockchain

As a new application model of distributed data storage, smart contract and other computer technologies in the Internet era, blockchain has been widely used in digital currency, payment and settlement, material supply chain, energy transaction, etc. It is essentially a decentralized database. Through its unique technical design and data management methods, it can support multi-party collaboration in different fields. Blockchain technology is a new research result in the field of encryption and security. It is closely related to network and information security, and can be used to solve some problems in this field, such as attack defense, data protection, privacy protection, identity authentication, crash recovery, etc. Security testing involves multiple subjects such as R&D manufacturers, evaluation agencies, operation and maintenance units, and system users. It just caters to the characteristics of blockchain multi-party participation, data sharing, and establishment of mutual trust mechanisms.
