Step 110, receiving the access request sent by the target node.

It should be noted that the target node can be any node that requests to join a blockchain network, and the "target" in the target node does not constitute any limitation on the target node.

In step 110, a user (for example, a platform user in FIG. 2 ) may perform an operation on the target node, so that the target node initiates an access request to the access authorization service device.

Optionally, the access request may be a Hyper Text Transfer Protocol (Hyper Text Transfer Protocol, HTTP) request, the request method of the access request may be POST, and the access request may also be called a License (permission) application, and the access request may be in the following form:

"applicantBid": "",

"chainCode": "",

"chainName": "",

"nodeName": "",

"nodeBid": "",

"nodeOrg": "",

"linkName": "",

"linkPhone": "",

"linkEmail": "",

"equipmentInfo":["",""],

"remark": "",

"link": "",

"type": ""

}

]

The above access request includes multiple parameters, and the description of each parameter can be found in Table 1 below:

Table 1

Step 120, from the access request, obtain the target node's basic node information, first link information to be connected, and node application type.

In step 120, the basic node information of the target node, the information of the first link to be connected, and the node application type of the target node may be directly extracted from the access request. Optionally, the node basic information may include the node address, node name, node operating unit name, contact name, contact phone number, contact email, etc. in Table 1; the first link information to be connected may include the Chain id, chain name, etc.; the node application type can correspond to the application type in Table 1.

Step 130, splicing the information of the first link to be connected and the node application type to obtain a splicing result.

Optionally, both the first to-be-connected chain information and the node application type can be in the form of characters or character strings, and the first to-be-connected chain information and the node The application type can be connected to obtain a new character string, and the new character string can be used as the concatenation result of the first pending link information and the node application type.

Step 140, determine the node constraint information corresponding to the concatenation result of the first to-be-connected link information and the node application type.

It should be noted that all blockchain networks that need to be reviewed by access authorization service equipment and all application types can be counted in advance. These blockchain networks include but are not limited to government affairs chains, business chains, etc. Based on all blockchain networks and all application types determined through statistics, multiple combinations can be formed, each combination includes chain information corresponding to a blockchain network and an application type, chain information and application types in different combinations /or the application type is different. For each combination mode, the chain information and the application type in the combination mode can be spliced to obtain a splicing result, and thus multiple splicing results corresponding to the multiple combination modes can be obtained one-to-one.

Assuming that the chain information in a certain combination is A and the application type is B, it can be determined which constraints the node needs to satisfy when it wants to become a node of type B in the blockchain network corresponding to A. These constraints A combination of conditions may be used as constraint information corresponding to the combination. In a similar manner, multiple constraint information corresponding to various combination methods can be obtained, and combined with the above multiple splicing results that correspond to multiple combination methods one-to-one, multiple splicing results and multiple constraint information can be obtained One-to-one correspondence between them.
