Technical Field

[0001] This invention relates to the field of blockchain technology, and in particular to a blockchain networking method, apparatus, device, and storage medium based on data isolation. Background Technology

[0002] Blockchain technology is built on a transmission network (also known as a blockchain network). Distributed node devices (hereinafter referred to as nodes) in the transmission network run blockchain programs to generate block data according to a preset consensus strategy, and use a chain data structure to verify and store block data, ultimately realizing a data anti-tampering mechanism and providing a new, secure, and reliable technical approach for business operations.

Consortium blockchains are limited to members of a specific group and a limited number of third parties. The main groups within consortium blockchains include banks, insurance companies, securities firms, business associations, large corporations, and their upstream and downstream partners. These groups require both strong confidentiality of sensitive data and good transparency of anonymized data to enable secure transactions among institutions within the blockchain and to allow external institutions to access business information from those within the consortium for business expansion. How to achieve these practical business needs on a blockchain is a pressing issue that needs to be addressed. Summary of the Invention

It establishes a public channel based on at least one consortium blockchain network. Any organization within the blockchain network joins this public channel. This public channel is a non-business transaction channel and does not participate in actual business transactions between organizations within the consortium blockchain. It is only used to synchronize anonymized data from all organizations, so that other organizations seeking to join can send networking requests to the designated consortium blockchain network or organization based on their corresponding anonymized data. The public channel completes the network entry operation and post-entry parameter configuration for the organizations seeking to join. By setting up a public channel, the anonymized data of any organization joining the public channel can be fully disclosed to the public. Simultaneously, because the public channel does not participate in actual business transactions between organizations, it ensures the data security of business transactions between organizations within the consortium blockchain.

Unless otherwise specified, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. Where there is no conflict, the various features of this invention and its embodiments can be combined with each other, all of which are within the scope of protection of this invention.

[0049] Blockchain technology is implemented on a blockchain network. Distributed node devices (hereinafter referred to as nodes) in the blockchain network run blockchain programs to generate and reach consensus on block data, thereby realizing a data anti-tampering mechanism and providing a new, secure, and reliable technical approach for business operations.

[0050] To facilitate understanding, a brief explanation of the blockchain network structure discussed in this paper is provided. To address the issues of ensuring the security of sensitive data and the full disclosure of anonymized data when conducting business on consortium blockchains, this paper treats one or more institutions as a single organization, and configures a public channel to which all organizations join. All organizations joining the public channel include at least one consortium blockchain. When two organizations belong to different consortium blockchains, data isolation between the two organizations is achieved while simultaneously allowing them to query / synchronize each other's anonymized data through the public channel, thus enabling the disclosure of anonymized data. Anonymized data refers to non-trade secret business data that can be disclosed, such as summary information of bond products (e.g., product name, issuance date). Sensitive data refers to non-trade secret business data that cannot be disclosed, such as actual subscription data of bond products (including price, user information, etc.).

[0051] It should be noted that any organization includes multiple nodes, including consensus nodes, business nodes, and sorting nodes. Actual business operations require the corresponding business channels; public channels do not participate in business transactions. Business transactions include the subscription, redemption, and purchase of financial products. Business channels are used for publicly anonymized information and non-trading transactions. Non-trading transactions include new organization joining. Anonymized information includes summaries of financial products; for example, a bond summary includes basic information such as the bond type but excludes sensitive information such as the subscription price.

[0052] Peer-to-peer (P2P) technology is an internet system without a central server, relying on a group of users to exchange information. Unlike centralized network systems with a central server, each user in a peer-to-peer network functions as both a node and a server.

[0053] Please see Figure 2 , Figure 2 The example illustrates a consortium blockchain network configured with a public channel, which corresponds to at least one consortium blockchain network. Organizations A, B, C, D, E, and F are organizations that have joined the public channel. Organizations A, B, and C constitute consortium blockchain ①, B, C, and D constitute consortium blockchain ②, C, D, and E constitute consortium blockchain ③, and F constitutes consortium blockchain ④. Organization N is an external organization that has not joined the public channel. In this blockchain outcome, other organizations can obtain anonymized data synchronized to the public channel from each organization, thereby understanding the basic information of the products being issued by each organization that has joined the public channel. For example, if an organization (Organization N or Organization F) is interested in the business corresponding to the anonymized data C synchronized to the public channel by Organization C, it can propose to join the consortium blockchain network where Organization C is located.

[0054] Example 1

[0055] Please see Figure 1 , Figure 1 The blockchain networking method based on data isolation in Embodiment 1 of the present invention configures a public channel based on at least one consortium blockchain network. The method includes:

[0056] S1: In response to the network access request information from the organization to be joined, generate the first consensus information;

[0057] Specifically, after the organization to join the network issues a network formation request, all organizations or some designated organizations that join the public channel reach a consensus on the network formation request to generate the first consensus information. If the organization to join is an external organization, the network formation request includes a request to join the public channel and a request to join the consortium blockchain network of the first target organization. If the organization to join the network is organization N, organization N needs to reach a consensus on joining the public channel first after issuing the network formation request, and then reach a consensus on joining the target consortium blockchain network. If the organization to join the network is organization F, then only the consensus on joining the target consortium blockchain network needs to be reached.

[0058] In one embodiment, the organizations to be added to the network include a first type of organization and a second type of organization, wherein the first type of organization is an organization that has not joined the public channel, and the second type of organization is an organization that has joined the public channel.

[0059] Specifically, if the organization to be joined is a first-type organization, the first consensus information includes the first consensus result and the second consensus result. The first consensus result indicates whether joining the public channel is allowed, and the second consensus result indicates whether joining the target consortium blockchain network is allowed. If the organization to be joined is a second-type organization, the first consensus information includes the second consensus result. The first and second consensus results are generated in different ways. The second consensus result includes at least one consensus sub-information, such as the first consensus result indicating agreement to join or rejection to join. The second consensus result includes consensus sub-information of at least one consortium blockchain corresponding to the first target organization. For example, if the first target organization is organization C, where organization A, organization B, and organization C constitute a consortium blockchain. Organizations B, C, and D constitute consortium chain ②; organizations C, D, and E constitute consortium chain ③; and organization F constitutes consortium chain ④. Consortium chains ①, ②, ③, and ④ are designated as pre-selected consortium chains. Organization F or N needs to join a consortium chain that includes organization C to transact with organization C. Therefore, the consortium chain including organization C conducts consensus for each organization seeking to join, obtaining consensus sub-information for each consortium chain. Consequently, the second consensus result includes multiple consensus sub-information pieces corresponding one-to-one with each pre-selected consortium chain. These consensus sub-information pieces contain consensus results indicating agreement to join or rejection to join. Based on these consensus sub-information pieces, the target consortium chain to which the organization seeking to join should be determined.

[0060] S2: Based on the consensus pass information of the first consensus information, the organization to be added to the target consortium blockchain network is added to the target consortium blockchain network through the public channel;

[0061] The public channel is a non-business transaction channel, and it is maintained by at least one organization that has joined the public channel.

[0062] Specifically, when the first consensus information indicates agreement to add the organization to the target consortium blockchain, if the organization is a first-type organization, the public channel adds the organization to the public channel and configures network parameters for the organization, including ID, number of nodes, organization permissions, etc. Then, the public channel adds the organization to the target consortium blockchain network again according to the configured network parameters. If the organization is a second-type organization, the public channel directly adds the organization to the target consortium blockchain network according to the organization's network parameters. If the first consensus result is rejection, the organization is rejected from being added to the public channel and / or added to the corresponding target consortium blockchain network, which is a consortium blockchain network containing the first target organization.

[0063] It should be noted that the public channel does not participate in any actual business transactions between organizations in any consortium blockchain. It is only used to synchronize anonymized data of each organization and to complete basic management functions, including new organization joining, new organization configuring ID, existing organizations establishing new consortium blockchains, and existing consortium blockchain organizations joining other consortium blockchains.

[0064] In one embodiment, generating network request information further includes:

[0065] S01: In response to the first request information from the organization to be joined to the network, generate a network invitation code based on the first request information;

[0066] S02: Generate the network request information based on the network invitation code;

[0067] The network request information includes the network invitation code.

[0068] In one embodiment, S01 includes:

[0069] S011: Obtain the target de-identification information in the public channel;

[0070] S012: Based on the target de-identification information, send the first request information to the first target organization corresponding to the target de-identification information for authorization review;

[0071] S013: Generate the network invitation code based on the authorization information of the first request information.

[0072] Specifically, after obtaining the de-identified target information from the public channel, the organization seeking to join the network submits an application to the first target organization corresponding to the de-identified target information. The first target organization reviews the organization seeking to join the network. If the organization seeking to join the network is a transaction target of the product published by the first target organization, a network invitation code is issued to the organization seeking to join the network. Network invitation information is generated using this network invitation code. If the first target organization believes that the organization seeking to join the network does not meet the requirements, it refuses to provide an invitation code to it. At the same time, the basic information of this application review is synchronized to the public channel, thereby improving the reliability and traceability of the organization seeking to join the network. It should be noted that the first target organization will not publish the review information of the organization seeking to join the network to the consortium blockchain where the first target organization is located, thereby reducing the consortium blockchain's processing of invalid data and saving computer resources. In a specific embodiment, the network request information is generated by the first target organization based on the network invitation code. The first target organization encrypts the network request information using preset processing rules, and then the organization seeking to join the network initiates the application.

[0073] In one embodiment, please refer to Figure 3 S1 includes:

[0074] S11: Broadcast the networking request information to each of the second target organizations;

[0075] S12: Based on the invitation information in the network request information, the consensus nodes of each of the second target organizations generate the first consensus information.

[0076] Specifically, since the organizations joining the public channel involve multiple consortium blockchains, if all organizations participate in consensus when there are a sufficient number of organizations joining, it will reduce consensus efficiency. Therefore, a selection of organizations is chosen as consensus voting organizations through an election process, and these organizations are designated as the second target organizations. The second target organizations differ depending on the network type. For example, when the organization to be joined is a first-type organization, the second target organizations for each organization joining the public channel are organizations elected by each consortium blockchain for consensus. For instance, if organization N needs to join the public channel, then the second target organization is an organization elected by each consortium blockchain. When organizations A of consortium chain ①, organization C of consortium chain ②, organization E of consortium chain ③, and organization F of consortium chain ④ join a consortium chain containing the first target organization, each second target organization is all or some of the organizations within each consortium chain. For example, the second target organizations include organizations A, B, and C corresponding to the consensus of consortium chain ①, organizations B, C, and D corresponding to the consensus of consortium chain ②, organizations C, D, and E corresponding to the consensus of consortium chain ③, and organization F corresponding to the consensus of consortium chain ④, thereby improving the consensus reliability of joining the target consortium chain network.

[0077] In one embodiment, if the organization to be added to the network is an external organization, the first consensus information includes a first consensus result on whether the organization to be added is allowed to join the public channel, and step S12 includes:

[0078] S121: Obtain consensus sub-information of other consensus nodes in each of the second target organizations;

[0079] S122: If each of the consensus sub-information includes target consensus information, then the target consensus information is used as the consensus sub-information of the current consensus node to obtain the first consensus result of the first consensus information;

[0080] The target consensus information is the consensus sub-information of the first target organization that issued the invitation information.

[0081] Specifically, when the organization to be joined is an external organization (i.e., the first type of organization), consensus must first be reached on joining the public channel. Any consensus node in each consortium blockchain will receive the consensus results from other consensus nodes. If the organization corresponding to the consensus node is the first target organization, then the consensus information of that consensus node is the target consensus information. If the organization corresponding to the consensus node is not the first target organization, then initial consensus information is generated. If the received other consensus nodes do not have target consensus information, then this initial consensus information is used as consensus sub-information. If the received other consensus nodes have target consensus information, then the target consensus information is used as the consensus sub-information of that consensus node. Thus, the first consensus result includes the initial consensus information of the consensus node itself and the target consensus result of the first target organization. Therefore, if the consortium blockchain does not contain... If the first target organization is selected, its consensus result will not contain the target consensus information. If the consortium blockchain it belongs to contains the first target organization, its consensus result will contain the target consensus information. If organization N needs to join a consortium blockchain network that includes organization B, the pre-selected consortium blockchain networks include consortium blockchain ① and consortium blockchain ②. In consortium blockchain ①, organization B's consensus result is "allowed to join". After receiving the "allowed to join" message from organization B, the consensus nodes of organizations A and C in consortium blockchain ① will replace their own consensus results with "allowed to join". In consortium blockchain ②, organization B's consensus result is also "allowed to join". After receiving the "allowed to join" message from organization B, organizations C and D in consortium blockchain ② will replace their own consensus results with "allowed to join". This method can verify whether the organization to join the network has been invited by an approved organization, and at the same time, it can lock the pre-selected consortium blockchain network.

[0082] In one embodiment, please refer to Figure 4 If the organization to be added to the network is an external organization, and the first consensus information includes a second consensus result regarding whether the organization to be added is allowed to join the target blockchain network, then step S2 includes:

[0083] S21: If the first consensus result of the first consensus information is passed, the public channel configures the organization parameters for the organization to be joined to the network.

[0084] S22: If the second consensus result of the first consensus information is passed, the organization to be added to the target blockchain network is added by the public channel.

[0085] In one embodiment, please refer to Figure 5 S2 includes:

[0086] S23: In response to the networking request information, at least one pre-selected consortium blockchain network is determined;

[0087] S24: Obtain the second consensus results corresponding to each of the pre-selected consortium blockchain networks in the first consensus information;

[0088] S25: Based on the second consensus results, the organization to be added to the network is added to the target consortium blockchain network corresponding to the first consensus information via the public channel.

[0089] In one embodiment, if all second consensus messages reject the organization seeking to join its pre-selected blockchain network, a new consortium blockchain network is formed as the target blockchain network.

[0090] Specifically, based on the network request information, the consortium blockchain networks that the organization seeking to join can join are determined, and these consortium blockchain networks are recorded as pre-selected consortium blockchain networks. Based on the second consensus results of each pre-selected consortium blockchain network, the pre-selected consortium blockchain networks that the organization seeking to join can join are determined based on all second consensus results. For example, if organization F needs to join a consortium blockchain network that includes organization B, then the pre-selected consortium blockchain networks include consortium blockchain ① and consortium blockchain ②. If the consensus rule is that the voting pass rate is greater than 50%, then joining is allowed; otherwise, joining is rejected. If the consensus result of organizations A and B in consortium blockchain ① is allowed to join, and the consensus result of organization C is rejected to join, then the first consortium blockchain network in consortium blockchain ① is selected as the first consortium blockchain network. If the consensus result of organization B in consortium chain ② is "allow to join," and the consensus result of organizations C and D is "reject to join," then the second consensus result of consortium chain ② is "reject to join." Organization F will then be added to consortium chain ①. If the second consensus result of all pre-selected consortium chain networks is "reject to join," a new consortium chain will be constructed based on the first target organization and the organizations to be added. The second consensus result will be synchronized to each organization or stored in a public channel. This ensures that the newly added organization can transact with the first target organization based on the blockchain, and the consensus result can also serve as a reference for other consortium chain organizations regarding the network consensus of the newly added organization.

[0091] The present invention provides a blockchain networking method, apparatus, and device based on data isolation. It establishes a public channel based on at least one consortium blockchain network. Any organization within the blockchain network joins this public channel. This public channel is a non-business transaction channel and does not participate in actual business transactions between organizations within the consortium blockchain. It is only used to synchronize anonymized data from all organizations, so that other organizations seeking to join can send networking requests to the designated consortium blockchain network or organization based on their corresponding anonymized data. The public channel completes the network entry operation and post-entry parameter configuration for the organizations seeking to join. By setting up a public channel, the anonymized data of any organization joining the public channel can be fully disclosed to the public. Simultaneously, because the public channel does not participate in actual business transactions between organizations, it ensures the data security of business transactions between organizations within the consortium blockchain.

[0092] Meanwhile, by establishing a public channel, when organizations in the consortium blockchain release products, they do not need to publish all product data to the blockchain. Instead, they can synchronize the anonymized data of the products to the public channel. When a transaction request is received, all data is then published to the blockchain through business transactions. Since blockchain technology uses distributed ledger technology, this ensures that products are obtained by as many organizations as possible, while avoiding the excessive amount of data that the blockchain needs to store, which would increase the burden on the blockchain.

[0121] Meanwhile, by establishing a public channel, when organizations in the consortium blockchain release products, they do not need to publish all product data to the blockchain. Instead, they can synchronize the anonymized data of the products to the public channel. When a transaction request is received, all data is then published to the blockchain through business transactions. Since blockchain technology uses distributed ledger technology, this ensures that products are obtained by as many organizations as possible, while avoiding the excessive amount of data that the blockchain needs to store, which would increase the burden on the blockchain.
