In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and in order to make the above and other objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention are described below. Attached Figure Description

[0042] Various other advantages and benefits will become apparent to those skilled in the art upon reading the following detailed description of preferred embodiments. The accompanying drawings are for illustrative purposes only and are not intended to limit the invention. Furthermore, the same reference numerals denote the same parts throughout the drawings.

[0048] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0049] Figure 1 A flowchart illustrating a method for implementing a relational network according to an embodiment of the present invention is shown. Figure 1 As shown, the method includes:

[0050] Step S110: Store the link information from the root node to the parent node of the relational network in the block of this node.

[0051] In this embodiment of the invention, the node has two meanings: in the first meaning, the node is a node in the blockchain; in the second meaning, the node is also a node in a relational network, and there can be multiple relational networks.

[0052] In a specific scenario, a company-specific app can be developed, and the accounts registered by employees using the app become accounts on the blockchain. Employees typically belong to only one department, but may participate in the development of multiple projects simultaneously. Therefore, each employee belongs to multiple different relationship networks.

[0053] Relationship networks are typically tree-like structures. Therefore, an employee's position within the relationship network can be determined, and correspondingly, the link information from the root node to the parent node of the relationship network can be stored in the locally stored block information.

[0054] Step S120: Receive a request with a node signature to add the target node to the relationship network.

[0055] Requests include node signatures, ensuring reliability and facilitating storage and traceability. For example, if employee A is a deputy manager of a project and wants employee B to join, they can invite B or have B proactively join the project's network.

[0056] Step S130: If this node has access permission to the relationship network, then issue a relationship network certificate for the target node; otherwise, send a request with this node's signature to the parent node to enable the target node to join the relationship network, based on the link information, until a node with access permission issues a relationship network certificate for the target node.

[0057] If employee A only has referral privileges but lacks access to the network of relationships (e.g., only supervisors have access), then a request with the target node's signature needs to be sent to the parent node based on the link information to add the target node to the network. This continues until a node with access privileges issues a network certificate for the target node. Conversely, if employee A has access privileges to the network of relationships, then a network certificate can be issued directly for the target node.

[0058] Each node's certificate issuance authority can only be granted by a node with the "authorize other nodes to issue certificates" permission to ensure reliability. The issued certificate serves as proof of identity.

[0059] It is easy to understand that although the above examples only illustrate enterprise organizations, they can be extended to other business scenarios and should not be construed as limiting the present invention. For example, in the Internet of Things (IoT) scenario, many smart terminals form a relationship network, such as the currently popular smart home, and this relationship network can also be implemented in the manner described above.

[0060] visible, Figure 1 The method shown has the advantage of establishing a relationship network using blockchain technology and ensuring the reliability of network members' joining through access permissions and certificate issuance, making it particularly suitable for specific business scenarios such as the Internet of Things and enterprise organizations.

[0061] In one embodiment of the present invention, the above method of issuing a relationship network certificate for the target node includes: when issuing the relationship network certificate, setting a limit on the number of levels of requests that the target node can transmit, and the limit on the number of levels of requests that the target node can transmit does not exceed the limit on the number of levels of requests that this node can transmit.

[0062] After joining a network of relationships, a node can interact with other nodes in the network to make business requests based on the blockchain, which can be understood as a "transaction" in the blockchain. Of course, the transactions here are not limited to the trading of financial assets, but also include the deployment of smart contracts.

[0063] To ensure the standardization of the relationship network, for example, since ordinary employees typically do not have direct business interactions with the CEO, it is required that ordinary employees cannot directly send business requests to the CEO. Therefore, a limit can be set on the number of levels at which target nodes can transmit requests.

[0064] It's easy to understand that when nodes are in the same network of relationships, the node with access permissions to the network is the ancestor node of the newly joined node. Taking a corporate organization as an example, this is usually at a relatively high leadership level. Therefore, the limit on the number of levels of requests that a newly joined node can transmit should not exceed the limit on the number of levels of requests that the node can transmit. Otherwise, it might lead to the strange situation where the team leader cannot communicate directly with the department head, but team members can.

[0065] In one embodiment of the present invention, the method further includes: receiving a service request sent by a target child node and processing the service request.

[0066] The business requests here are also implemented based on blockchain, which ensures the traceability and reliability of business requests. A detailed explanation follows.

[0067] In one embodiment of the present invention, the above method for processing a business request includes: determining whether the business request is valid; if it is invalid, returning a response message of refusal to execute to the target child node.

[0068] The term "legality" here can encompass multiple dimensions, such as whether the data format is a pre-agreed format, whether the data content is compliant, and so on.

[0069] In one embodiment of the present invention, the method further includes: storing the permissions of each child node in the block of the current node; processing the business request includes: determining whether the permissions corresponding to the business request match the permissions of the target child node; if they do not match, returning a reply message of refusal to execute to the target child node.

[0070] In a smart home scenario, a smart device can send detected information such as humidity and temperature to an app, which can then adjust accordingly. The smart device can be considered a child node of the app. Therefore, the smart device does not have the authority to terminate the app's operation. If a hacker infiltrates the smart device and attempts to cause further damage by terminating the app, the app can refuse to execute the termination request based on its permissions.

[0071] In one embodiment of the present invention, the above method of processing a service request includes: if at least one recipient of the service request is an ancestor node contained in the link information, then the service request is forwarded to the parent node.

[0072] For example, some approvals require more than one node to complete. In such cases, the business request may involve multiple recipients. If the recipient is an ancestor node contained in the link information, the business request is forwarded to the parent node. This process is repeated layer by layer to ensure the correct processing of the business request.

[0073] In one embodiment of the present invention, the above method for processing a business request includes: performing corresponding processing according to the type of the business request, wherein the type of the business request includes transactions and / or messages.

[0074] A business request can be formatted as follows: {signature (node ​​signature), recipient address, message / transaction, certificate, other}

[0075] The receiver address format can be: parent + N-level address... parent + 1-level address, parent address, current node address. Furthermore, this address can follow the simplest principle, meaning it only needs to be written up to the lowest address of the same branch level.

[0076] For example, the root node ROOt has two sibling nodes A and B. A has two sibling nodes A1 and A2. A1 has two sibling nodes A11 and A12. A2 has two sibling nodes A21 and A22. B has three sibling nodes B1, B2 and B3. B1 has two sibling nodes B11 and B12.

[0077] Therefore, for a service request sent from A11 to A12, the recipient address only needs to be A12. For a service request sent from A21 to B11, the recipient address needs to be B, B1, or B11.

[0078] Specifically, in one embodiment of the present invention, the above method includes performing corresponding processing according to the type of business request: if the business request is a message and at least one recipient of the business request is another child node, then the message is forwarded to the corresponding child node, and a reply message with the signature of this node is sent to the corresponding child node and the target child node.

[0079] This enables the parent node to monitor messages from child nodes. It can also be combined with the aforementioned embodiments, for example, by first determining whether a business request is legitimate, and then forwarding it if it is legitimate.

[0080] For example, if a malicious employee wants to spread false information within the company, the parent node can quickly detect this and promptly cut off the propagation path, and take further action.

[0081] In one embodiment of the present invention, the above method, performing corresponding processing according to the type of business request, includes: if the business request is a transaction, then deploying and / or executing the contract on this node according to the content of the business request.

[0082] Specifically, smart contracts can be pre-deployed on the blockchain, such as awarding employees corresponding rewards based on their quarterly workload reaching a certain level. Business requests can then be considered workload, and rewards can be distributed according to the contract.

[0083] Figure 2 A schematic diagram of a device for implementing a relational network according to an embodiment of the present invention is shown. Figure 2 As shown, the apparatus 200 for implementing the relational network includes:

[0084] Storage unit 210 is adapted to store the link information from the root node to the parent node of the relational network in the block of this node.

[0085] In this embodiment of the invention, the node has two meanings: in the first meaning, the node is a node in the blockchain; in the second meaning, the node is also a node in a relational network, and there can be multiple relational networks.

[0086] In a specific scenario, a company-specific app can be developed, and the accounts registered by employees using the app become accounts on the blockchain. Employees typically belong to only one department, but may participate in the development of multiple projects simultaneously. Therefore, each employee belongs to multiple different relationship networks.

[0087] Relationship networks are typically tree-like structures. Therefore, an employee's position within the relationship network can be determined, and correspondingly, the link information from the root node to the parent node of the relationship network can be stored in the locally stored block information.

[0088] The receiving unit 220 is adapted to receive a request with a node signature to add the target node to the relational network.

[0089] Requests include node signatures, ensuring reliability and facilitating storage and traceability. For example, if employee A is a deputy manager of a project and wants employee B to join, they can invite B or have B proactively join the project's network.

[0090] The processing unit 230 is adapted to issue a relationship network certificate to the target node if the node has access permission to the relationship network; otherwise, it sends a request with the node's signature to the parent node to enable the target node to join the relationship network, based on the link information, until a node with access permission issues a relationship network certificate to the target node.

[0091] If employee A only has referral privileges but lacks access to the network of relationships (e.g., only supervisors have access), then a request with the target node's signature needs to be sent to the parent node based on the link information to add the target node to the network. This continues until a node with access privileges issues a network certificate for the target node. Conversely, if employee A has access privileges to the network of relationships, then a network certificate can be issued directly for the target node.

[0092] Each node's certificate issuance authority can only be granted by a node with the "authorize other nodes to issue certificates" permission to ensure reliability. The issued certificate serves as proof of identity.

[0095] In one embodiment of the present invention, in the above-described apparatus, the processing unit 230 is adapted to set a limit on the number of levels of requests that a target node can transmit when issuing a relational network certificate, and the limit on the number of levels of requests that a target node can transmit does not exceed the limit on the number of levels of requests that the node itself can transmit.

Otherwise, it might lead to the strange situation where the team leader cannot communicate directly with the department head, but team members can.

[0099] In one embodiment of the present invention, the processing unit 230 in the above-described apparatus is further adapted to receive service requests sent by the target child node and process the service requests.

[0100] The business requests here are also implemented based on blockchain, which ensures the traceability and reliability of business requests. A detailed explanation follows.

[0101] In one embodiment of the present invention, in the above-described apparatus, the processing unit 230 is adapted to determine whether the service request is valid, and if it is invalid, to return a response message of refusal to execute to the target child node.

[0108] A business request can be formatted as follows: {signature (node ​​signature), recipient address, message / transaction, certificate, other}

[0109] The receiver address format can be: parent + N-level address... parent + 1-level address, parent address, current node address. Furthermore, this address can follow the simplest principle, meaning it only needs to be written up to the lowest address of the same branch level.

[0111] Therefore, for a service request sent from A11 to A12, the recipient address only needs to be A12. For a service request sent from A21 to B11, the recipient address needs to be B, B1, or B11.

[0112] Specifically, in one embodiment of the present invention, in the above-described apparatus, the processing unit 230 is adapted to forward the message to the corresponding sub-node and send a reply message with the signature of the current node to the corresponding sub-node and the target sub-node if the service request is a message and at least one recipient of the service request is another sub-node.

[0113] This enables the parent node to monitor messages from child nodes. It can also be combined with the aforementioned embodiments, for example, by first determining whether a business request is legitimate, and then forwarding it if it is legitimate.

[0118] In summary, the technical solution of this invention stores the link information from the root node to the parent node of the relationship network in the block of this node. It receives a request with a node signature to allow a target node to join the relationship network. If this node has the access permission for the relationship network, it issues a relationship network certificate for the target node; otherwise, it sends a request with its own signature to the parent node to allow the target node to join the relationship network, based on the link information, until a node with access permission issues a relationship network certificate for the target node.
