In order to solve the prominent problems existing in the management of military equipment quality information,this paper proposed a method of equipment quality information management using blockchain technology. Three types of problems existing in the current equipment quality information management were analyzed,and the feasibility of using blockchain technology in equipment quality information management was discussed. A distributed equipment quality information management model based on blockchain was established and its security was analyzed. The results show that,on the premise of ensuring the safety and reliability of equipment quality information,the model can effectively improve the efficiency and level of equipment information management,and better adapt to the demand for equipment quality information in the future battlefield.
