To improve the information security and reliable interaction of each link in the dispatching and issuing process， this paper presents a block chain technology to verify the key link data of dispatching operation. First， after checking and verifying the operation instructions， the up-chain storage is carried out， and then the operation instructions are sent to the corresponding dispatching objects. At the same time， each node of the block chain will automatically synchronize to the corresponding up-chain information. Secondly， when dispatching objects at all levels execute operation instructions， they verify the consistency with the operation instructions in the local block chain nodes， and then execute the subsequent operations after the validation has passed. Finally， during the execution of the operation instructions， the operation information of each step is updated to the block chain to form a continuous execution and verification process.
