The embodiment of the invention discloses a service node management method, a device, equipment and a storage medium, and belongs to the technical field of computers. The method comprises the steps ofreceiving electronic bill information sent by multiple service nodes; when the system time reaches an out-of-block time threshold, generating a target block according to the electronic bill information corresponding to each service node, and adding the target block into blockchain; obtaining the target block and the historical block from the block chain according to the statistical period duration, and counting the total electronic bill issuing amount of each service node in the statistical period duration according to the target block and the historical block; and performing anomaly detection on the operation state of each service node based on the total electronic bill issuing amount. By adopting the method, the management and control of the core node on the service node can be enhanced, and the statistical efficiency is further improved.
