The network architecture adopted by the traditional blockchain member management is the P2P network architecture. Each computer located in the bitcoin network is peer-to-peer with each member node providing network services collectively, without any "special" member nodes. Each member node is perfectly equal. Each member node provides services to the outside and simultaneously uses the services provided by other member nodes.
FIG. 1 illustrates a conventional blockchain membership diagram.
As shown in fig. 1, a conventional blockchain network is a collection of member nodes operating in accordance with the P2P protocol. Peer-to-peer relationships exist between each member node. In the conventional blockchain, after each new member node appears, the new member node must actively contact the existing member nodes in order to cooperate with the member nodes in the whole blockchain network. Thus, the method can be added into the big family of the bitcoin network.
In the traditional block chain network, the process of establishing contact between a new member node and an existing member node is as follows: after acquiring information such as neighbor node IP and the like, the new member node actively sends own IP information to the neighbor node. The neighbor node of the new member node will also actively pass the address information of the new member node to its neighbors. The process is repeated in a circulating mode, and finally, the information of all the member nodes is updated.
Although all nodes can finally obtain the information of the new member node through the information synchronization for several times, the above process has the following disadvantages: the synchronization period is too long, the influence of the network scale is large, and the efficiency is low; only IP information is transmitted between nodes, and upper-layer application cannot be borne; once the member nodes change, network uncertainty occurs, and information fluctuation transmission is caused; each member node only has partial neighbor node information, and information transmission cannot directly reach global members.
Aiming at the problems, the invention provides a member management method of a block chain, which adopts a mixed secondary network architecture to realize the maintenance of global cataloging member information, can meet the requirements of short-time convergence, node change and member partition, and realizes the distribution of super-large-scale global consistency member cataloging on the basis of very small data transmission quantity. For example, the member node size is hundreds of thousands of points, and the global list table size is about 1M.
The technical solution of the present application will be described in detail below with reference to the accompanying drawings.
Fig. 2 illustrates a block chain secondary network architecture diagram according to an example embodiment of the present application.

As shown in FIG. 2, in the two-level network architecture, the first level is composed of N members N1～NnAnd (4) forming. The second level is a global cataloging cluster consisting of m global cataloging nodes O1～OmAnd (4) forming. An exemplary embodiment according to the present application m is 4. And the cataloging information of each node in the global cataloging cluster is kept consistent in real time. And each external global catalog node is respectively responsible for global catalog table application and refreshing of a plurality of member nodes. Correspondingly, the global catalog table is divided into m global catalog table paragraphs according to the number of global catalog nodes, and each global catalog node is responsible for maintaining a corresponding global catalog table paragraph.

Further, the member management method further includes:
at S40, the global inventory node group initiates a survival acknowledgement to the member upon expiration of the survival countdown. For example, each global inventory node initiates a member survival acknowledgement every 12 hours per partition.
At S50, the global inventory node group refreshes the global inventory table according to the heartbeat fed back by the members. And each node regularly feeds back heartbeat confirmation information to the cataloged cluster nodes. And the global cataloging node set judges the survival condition of the member node through the confirmation information fed back by the member node. And deleting nodes without heartbeat information in time, and refreshing the global cataloging information, thereby realizing the maintenance of the global cataloging table.
According to some embodiments of the present application, the global catalog node, at S20, synchronizes the member information and updates a global catalog table within a global catalog cluster, including: and the global catalog node updates the local global catalog table information and sends the updated local global catalog table to other nodes of the global catalog cluster. Further, the local global catalog table information includes a corresponding number of global catalog table paragraphs divided according to the number of global catalog nodes, and the global catalog nodes are responsible for maintaining the corresponding global catalog table paragraphs.
For example, the global catalog table is divided into 4 segments, and 4 global catalog nodes are respectively responsible for member nodes in the corresponding segments. And when the member node information in a certain paragraph is updated, the member node is responsible for maintaining the global catalogue node of the member node to update the corresponding global catalogue table paragraph and sending the updated global catalogue table paragraph to other global catalogue nodes.

and the new member node sends a registration application to the global cataloging node. And the new member node calculates the domain name of the global cataloging node applying for registration according to the hardware ID information of the new member node. For example, as shown in fig. 2, the global catalog node includes 4 nodes, and the new member node may balance 6 according to its own hardware ID number. And if the remainder value is 4, reporting the registration information to the 4 th global cataloging node. The subsequent global catalog node is responsible for the information maintenance and refreshing of the member node.

The new member node obtains the updated global catalog table from the global catalog cluster. And according to the updated global catalog table, the new member sends announcement information to the associated member node of the new member to remind the associated member to acquire the updated global catalog table from the global catalog cluster. According to some embodiments of the present application, the associated member nodes are part of the member nodes determined by an algorithm according to the member information in the global list table. For example, the associated member node is determined based on a comparison of certain digits of the member's ID to predetermined characters.
