An intelligent military blockchain security management architecture is proposed. Relying on the hierarchical architecture of the data layer, network layer, consensus layer, contract layer and application layer of the blockchain system, the multidimensional detection, intelligent analysis and evaluation, and visual security early warning of abnormal behavior data are carried out by using big data and artificial intelligence technology with real-time collection of various original data information such as nodes, chains, contracts, transactions, accounts and consensus, and security events are quickly located and handled, so as to realize the intelligent linkage closed-loop process of military blockchain security management.
