Node monitoring method and device based on block chain, electronic equipment and product

The invention relates to the technical field of communication, and provides a node monitoring method and device based on a block chain, electronic equipment and a product. The method comprises: broadcasting service information collected by a first edge node to each first target node, the first target node being an upper layer node of a first node link corresponding to the first edge node; and under the condition that any service information fails to be verified, traversing the service information in each first target node, and determining a first abnormal target node in each first target node. According to the embodiment of the invention, whether the data is lost or missed can be quickly monitored, and the fault node with the data lost or missed can be analyzed conveniently, so that the consistency and integrity of the data are further ensured. 本申请涉及通信技术领域，提供一种基于区块链的节点监测方法、装置、电子设备及产品。所述方法包括：将第一边缘节点采集的业务信息广播到各个第一目标节点，其中，所述第一目标节点是所述第一边缘节点对应的第一节点链路的上层节点；在任一所述业务信息验证失败的情况下，遍历各个所述第一目标节点中的业务信息，确定各个第一目标节点中的第一异常目标节点。本
