Internet of Things security operation system based on block chain

The invention discloses an Internet of Things security operation system based on a block chain, and particularly relates to the field of block chain Internet of Things power equipment security, the system comprises a power utilization platform, the power utilization platform comprises a plurality of power equipment; the operation subsystem is connected with the power utilization platform in series and used for receiving the unverified secret key, and if communication bytes in the unverified secret key are matched with communication bytes in the safety secret key which changes in real time, the operation subsystem is allowed to control the operation states of various power devices in the power utilization platform. The identity of a visitor is reasonably verified by comparing the matching of an unverified key and a security key at the same intercept point time, when the matching is inconsistent, the position of the IP of the communication terminal can be tracked by utilizing a tracking technology so as to obta
