Five-prevention lock management method and system based on block chain

The invention provides a five-prevention lock management method and system based on a block chain, a task block, a key block, a five-prevention lock block and an equipment block are constructed, each of the task block, the key block, the five-prevention lock block and the equipment block comprises a verification code, each verification code comprises at least two independent parts which are respectively stored, and once the verification code is modified, the number of the verification code is changed, so that the possibility of tampering management data of the five-prevention lock is avoided; and a server packs the total task number, the operation time of each subtask, the equipment state, the operator and the video information to form a cloud block for packing, so that later calling and consulting are facilitated, and the problem that related records of each piece of equipment cannot be found due to the fact that a memory is full is also avoided. 本公开提供了一种基于区块链的五防锁具管理方法及系统，构建了任务区块、钥匙区块、五防锁区块和设备区块，且任务区块、钥匙区块、五
