Multi-node hopping path tracking and testing method and device based on block chain

The invention provides a multi-node hopping path tracking and testing method and device based on a block chain, and the method comprises the steps: selecting a father node from a block chain network, enabling all remaining nodes to serve as child nodes, and enabling all child nodes to subscribe to the father node, thereby obtaining the needed information; all the child nodes maintain information of the child nodes on one hand, maintain information of the child nodes adjacent to the child nodes on the other hand, and publish all the information owned by the child nodes to the father node for registration; in the block chain network, a starting node and a terminal node are determined, and inter-node hopping path tracking planning is carried out for an intermediate node; a gateway module is deployed at each intermediate node, and an input signal and an output signal passing through the node are recorded, so that a selected node path is analyzed, and the reliability of multi-node hopping path tracking is ensured.
