Blockchain technology has been widely validated in multiple fields. Faced with prominent issues in military equipment quality information management, it can be widely used in equipment quality information management business scenarios by leveraging its advantages of high security, irreversibility, and tamper resistance.Any user entering the equipMent quality inforMation ManageMent Model Must have identity registration and authentication. Only those users who successfully pass identity authentication can enter the equipMent quality inforMation ManageMent Model and query and Manage equipMent quality inforMation according to their identity perMissions. The user"s identity registration authentication inforMation and the user"s operation records on equipMent quality inforMation will be stored in the blockchain.This Model can effectively iMprove the efficiency and level of equipMent inforMation ManageMent while ensuring the safety and reliability of equipMent quality inforMation, and better adapt to the needs of future battlefield for equipMent quality inforMation.
