[0002] Blockchain technology is a new type of decentralized information technology. The data or information stored in the blockchain has the characteristics of "unforgeable", "full traceability", "traceability", "openness and transparency", and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects.

[0003] A smart contract is a computer protocol designed to disseminate, verify or execute contracts in an information-based manner. It allows for trusted transactions without a third party, and these transactions are traceable and irreversible. Running smart contracts on the blockchain can ensure that the entire process is open, transparent and cannot be tampered with.

[0063] The technical solution of the present disclosure is further described in detail below through the accompanying drawings and embodiments.

[0064] The flowcharts of some embodiments of the network resource interaction method disclosed in the present invention are as follows: Figure 1 shown.

[0065] In step 101, a node of the interactive network receives a first resource interaction request, the first resource interaction request including a user identifier, a source application identifier, a target application identifier, and an interactive source resource amount. In some embodiments, the node of the interactive network that receives the first resource interaction request also belongs to the application blockchain network of the source application of the request.

[0066] In some embodiments, a user may initiate a first resource interaction request directly to a shared node between the interactive network and the source application, or may initiate a first resource interaction request to other blockchain network nodes of the source application, and through the interaction between application blockchain network nodes of the source application (e.g., publishing blocks), the first resource interaction request may reach the shared node between the interactive network and the source application.

[0067] In some embodiments, the interactive network is a blockchain network. There are multiple nodes in the interactive network that belong to the same or different application blockchain networks.

[0068] In step 102, the interactive network generates an interactive target resource amount according to the pre-stored interaction ratio between the source application and the target application, and the interactive source resource amount. In some embodiments, each node in the interactive network may have a smart contract, so that the interactive target resource amount calculation can be performed at any node. For example, the node receiving the first resource interaction request on the interactive network performs the calculation by itself and stores the calculation result on the chain.

[0069] In some other embodiments, an interactive server may be provided, and one or more nodes in the interactive network are connected to the interactive server. The interactive server stores a smart contract. The node of the interactive network sends the first resource interaction request to the interactive server, and obtains the interactive target resource amount from the interactive server.

[0070] In some embodiments, when a smart contract changes, the smart contract in the interactive network or interactive server is updated.

[0071] In some embodiments, if the node receiving the first resource interaction request in the above step 101 is not connected to the interactive server, the node connected to the interactive server obtains the first resource interaction request through the interactive operation between the blockchain network nodes, so as to obtain the interactive target resource amount from the interactive server.

[0072] In some embodiments, the smart contract can be a contract between two applications. When the nodes in the interactive network belong to more than two applications, the corresponding interaction ratio pre-stored information can be queried based on the identification of the target application and the identification of the source application, and then the interaction target resource amount can be generated based on the queried interaction ratio pre-stored information and the interaction source resource amount, thereby further improving the flexibility and reliability of resource interaction between different applications.

[0073] In step 103, second resource interaction information is sent to a node of the application blockchain network belonging to the target application in the interactive network, and the second resource interaction information includes a user identifier and an interactive target resource amount.

[0074] In some embodiments, the node that obtains the interactive target resource amount through its own calculation or from the interactive server in step 102 can generate the second resource interactive information, and realize the information transmission between the nodes of the interactive network through the message link.

[0075] In some embodiments, after obtaining the updated block in the network, the nodes belonging to each application blockchain network in the interactive network determine whether it is a request that requires itself to perform subsequent processing by matching the target blockchain. If the match is successful, the operation in step 104 is performed; otherwise, the request is ignored.

[0076] In step 104, the node in the application blockchain network of the target application updates the user's resource volume stored in the application blockchain network according to the user identifier and the interaction target resource volume, and feeds back interaction success information to the interaction network.

[0077] In some embodiments, the relevant nodes of the target application can generate an updated resource amount based on the user's resource amount currently stored in the blockchain application network and the interactive target resource amount; generate a block based on the updated resource amount and the user identifier and publish it on the application blockchain network of the target application.

[0078] In step 105, upon receiving the successful interaction instruction, the node of the application blockchain network belonging to the source application in the interaction network updates the resource amount of the user stored in the application blockchain network to which it belongs according to the interaction source resource amount.

[0079] In some embodiments, the relevant nodes of the source application can generate an updated resource amount based on the user's resource amount currently stored in the blockchain application network and the interactive source resource amount; generate a block based on the updated resource amount and the user identifier and publish it on the application blockchain network of the source application.

[0080] Through this method, users can exchange resources in different application blockchain networks through the interactive network, so that user resources in different application blockchain networks can circulate and interact, reducing the isolation between blockchain networks and improving the flexibility of blockchain networks.

[0081] In some embodiments, each resource interaction may be written and stored in the interactive network, so that the resource interaction can be queried through the credible interactive network, thereby improving the credibility of the resource interaction operation.

[0082] Flow charts of other embodiments of the network resource interaction method disclosed in the present invention are as follows: Figure 2 shown.

[0083] In step 201, a predetermined number of nodes are selected in each application blockchain network according to the paths between the nodes of the application blockchain network and the paths between the nodes of the application blockchain network and the predetermined initial nodes. The predetermined initial nodes are nodes in the interactive network that do not belong to any application blockchain network.

[0084] In some embodiments, node selection can be performed based on the path length between nodes of each application blockchain network and the path length between the application node and the initial node predetermined by the interactive network. In some embodiments, nodes on the path with strong processing capabilities and faster transmission speeds can also be selected based on the computing power of the node, path bandwidth, etc., to improve the performance of the interactive network.

[0085] In some embodiments, the predetermined number may be 1, thereby preventing multiple shared nodes belonging to the same application from receiving and processing requests at the same time. In other embodiments, the predetermined number may be greater than 1, thereby improving the robustness of the system. In some embodiments, priorities may be set for multiple shared nodes of the same application, and nodes with higher priorities may preferentially process requests related to the application to which they belong.

[0086] In step 202, the selected nodes and the paths between the nodes are merged into the connection of the initial node, and an interactive network consisting of the initial node, the selected nodes and the paths between the nodes is obtained, and the interactive network is a blockchain network.

[0087] In step 203, any node of the application blockchain network of the source application generates a first resource interaction request according to the user request and sends at least one common node with the interaction network.

[0088] In step 204, a shared node of the interactive network and the application blockchain network of the source application receives a first resource interaction request.

[0089] In some embodiments, when the node that directly receives the user request is a shared node, the above steps 203 and 204 can be omitted, and the first resource interaction request is directly generated according to the user request, and then step 205 is executed.

[0090] In step 205, an interactive target resource amount is generated according to the pre-stored interactive ratio between the source application and the target application, and the interactive source resource amount.

[0091] In step 206, second resource interaction information is sent to a node of the application blockchain network belonging to the target application in the interactive network, and the second resource interaction information includes a user identifier and an interactive target resource amount.

[0092] In step 207, the node in the application blockchain network of the target application updates the user's resource volume stored in the application blockchain network according to the user identifier and the interaction target resource volume, and feeds back interaction success information to the interaction network.

[0093] In step 208, upon receiving the successful interaction instruction, the node of the application blockchain network belonging to the source application in the interaction network updates the resource amount of the user stored in the application blockchain network to which it belongs according to the interaction source resource amount.

[0094] Through this method, an interactive network can be generated based on network topology and node resources, and resource exchange channels between different application blockchain networks can be built. Then, resource interaction can be carried out based on the interactive network, which utilizes the decentralized characteristics of blockchain, improves the credibility of resource interaction, and reduces the management burden.

[0095] The flowcharts of some embodiments of the resource interaction network generation method disclosed in the present invention can be as follows: Figure 2 As shown in steps 201 and 202.

[0096] Through this method, an interactive network with nodes of different application blockchain networks can be built, so that user resources in different application blockchain networks can circulate and interact, reducing the isolation between blockchain networks and improving the flexibility of blockchain networks.

[0097] Flow charts of other embodiments of the resource interaction network generation method disclosed in the present invention are as follows: Figure 3 shown.

[0098] In step 301, for each application blockchain network, the path weight between nodes is obtained according to the network communication delay between nodes and the average computing power of the computer.

[0099] In some embodiments, the path weights between nodes are calculated using two indicators: network communication delay and average computer computing power, and the indicator weights are: w1, w2, and w1+w2=1. According to the evaluation values ​​of the indicators corresponding to the network communication delay and the average computer computing power, the path weight is calculated using a linear weighting method.

[0100] For example, the network communication delay between nodes is evaluated as v1, and the average computing power of the computer is evaluated as v2. The smaller the network communication delay, the larger v1 is, and the larger the average computing power of the computer, the larger v2 is. The path weight between nodes is:

[0101] Weight = f(v1*w1, v2*w2)

[0102] =v1*w1+v2*w2

[0103] In step 302, the target path between the nodes is obtained according to the path weights between the nodes through the improved Floyd algorithm.

[0104] The traditional Floyd algorithm is a classic algorithm for finding the shortest path between multiple source points. In the present disclosure, the path weight Weight is used as the weight of the path, and the problem of finding the minimum sum of the weights is converted into the problem of finding the maximum sum of the weights.

[0105] In some embodiments, according to the initial node of the interactive network and the nodes of each application blockchain network, and the paths between the nodes, an adjacency matrix between the nodes is obtained, wherein the elements in the adjacency matrix identify the weights of the paths between the nodes; according to the state transfer equation:

[0106] dp[i][j]=max(dp[i][j],[dp[i][n]+dp[n][j]] / 2)

[0107] Update the adjacency matrix to obtain the target matrix, where the elements in the target matrix identify the paths with the highest weights between nodes; where dp[i][j] is the element in the i-th row and j-th column of the adjacency matrix, dp[i][n] is the element in the i-th row and n-th column of the adjacency matrix, and dp[n][j] is the element in the n-th row and j-th column of the adjacency matrix. i, j, and n are positive integers less than or equal to the sum of the number of initial nodes and the number of nodes in each application blockchain network.

[0108] Further, according to the target matrix, a predetermined number of nodes are selected in the application blockchain network of each application in the order of weight with the initial node from high to low, and in the order of weight with the nodes selected to be incorporated into the interactive network from high to low.

[0109] In step 303, nodes are selected in each application blockchain network in descending order of the weight of the target path until the number of selected nodes in each application blockchain network reaches a predetermined number.

[0110] In some embodiments, a predetermined set of initial nodes may be set first. k ,In the initial state, the number of selected nodes in each application blockchain network is 0.

[0111] For each application blockchain network, perform the following operations:

[0112] According to the target matrix, get the node corresponding to i belongs to {C} k , the node corresponding to j belongs to the largest dp[i][j] of the current application blockchain network, determine the corresponding i and j; increase the number of selected nodes in the current application blockchain network by 1, and merge the node corresponding to j into the set {C} k, merge it into the set {C} k The node is selected as the first node in the current blockchain network.

[0113] Through the above operations, a node is selected in each application blockchain network.

[0114] When the predetermined number is greater than 1, the following operations are repeated for each application blockchain network until the number of selected nodes in each application blockchain network is equal to the predetermined number:

[0115] According to the target matrix, obtain the maximum dp[i][j] where the node corresponding to i belongs to the application blockchain network and the node corresponding to j does not belong to the same application blockchain network, and determine the corresponding i and j;

[0116] If the node corresponding to j belongs to the set {C} k , and the node corresponding to i does not belong to the set {C} k , if the number of selected nodes in the application blockchain network to which the node corresponding to i belongs is less than the predetermined number, the number of selected nodes in the application blockchain network to which the node corresponding to i belongs is increased by 1, and the node corresponding to i is incorporated into the set {C} k ;

[0117] If the node corresponding to j does not belong to the set {C} k , and the node corresponding to i does not belong to the set {C} k , if the number of selected nodes in the application blockchain network to which the node corresponding to i belongs is less than the predetermined number, the number of selected nodes in the application blockchain network to which the node corresponding to i belongs is increased by 1, and the node corresponding to i is incorporated into the set {C} k ;

[0118] If the node corresponding to j does not belong to the set {C} k , the node corresponding to i does not belong to the set {C} k , if the number of selected nodes in the application blockchain network to which the node corresponding to j belongs increases by less than the predetermined number, the number of selected nodes in the application blockchain network to which the node corresponding to j belongs is increased by 1, and the node corresponding to j is incorporated into the set {C} k .

[0119] In step 304, the selected nodes and the paths between the nodes are merged into the connection of the initial node, and an interactive network consisting of the initial node, the selected nodes and the paths between the nodes is obtained, so that resource interaction between the application blockchain networks is performed through the interactive network, and the interactive network is a blockchain network.

[0120] Through this method, a predetermined number of nodes can be screened out according to the weights between the nodes and the existing nodes in the interactive network, thereby minimizing the network communication delay of the interactive network, improving the average computing power of the computer in the interactive network, avoiding excessive processing burden on the nodes caused by being incorporated into the interactive network, reducing the impact on the application blockchain network, and improving the robustness of the system.

[0121] In some embodiments, the operations in steps 303 and 304 are exemplified as follows:

[0122] Target matrix dist[i][j], i = {0, 1, 2, ..., the sum of the number of initial nodes and the number of nodes of each application blockchain network}, j = {0, 1, 2, ..., the sum of the number of initial nodes and the number of nodes of each application blockchain network}.

[0123] (1) Assume that the set of initial nodes of the interaction network is {C} k , the node set of the application blockchain network A is {D}, find dp[i][j] (where: i∈{C} k , j∈{D}), the nodes corresponding to i and j are respectively denoted as C i , D j ; Then select D from the application blockchain network A j Nodes join the interactive network and D j Join k .

[0124] Similarly, other application blockchain networks select one node to join the interactive network in this way.

[0125] After this step, each points system needs to select f-1 nodes to join the points chain network.

[0126] (2) Assume that the application blockchain network A has not yet completed the selection of f (f is a predetermined number) nodes, and its node set is still recorded as {D}, then now find dp[i][j] (where: i∈{D}, And nodes i and j are different ∈{C} k ), the nodes corresponding to i and j are respectively recorded as D i , R, then it is divided into the following three cases:

[0127] a) If j∈{C} k ,and Then select D from the blockchain network A i Nodes join the interactive network and D i Join k ;

[0128] b) If j belongs to the application blockchain network B, and the number of selected nodes in the application blockchain network B is less than f:

[0129] like Then select D in the application blockchain network A i Nodes join the interactive network and D i Join k ;

[0130] If the node Then select R node in the application blockchain network to which R node belongs to join the interactive network, that is, add R to {C} k ;

[0131] c) In other cases, no node is selected to join the interactive network in this round.

[0132] (3) Repeat step 2 until the application blockchain network A completes the selection of f nodes.

[0133] Similarly, other application blockchain networks follow this method to complete the selection of f nodes.

[0134] (4) After completing the above steps, N application blockchain networks are completed, and each application blockchain network selects f nodes, for a total of N*f nodes.

[0135] In this way, the best possible performance of the interactive network can be ensured.

[0136] Schematic diagrams of some embodiments of the network resource interaction system disclosed in the present invention are as follows Figure 4 shown.

[0137] The network resource interaction system may include an interactive network 41. The interactive network 41 is a blockchain network having multiple nodes connected by links. There are multiple nodes in the interactive network belonging to the same or different application blockchain networks, such as nodes 4211, 4221, ... 42N1, where N is the number of application blockchain networks, and N is an integer greater than or equal to 2.

[0138] During the operation of the interactive network, a node of the application blockchain network belonging to the source application can receive a first resource interaction request, which includes a user identifier, a source application identifier, a target application identifier, and an interactive source resource amount; the node in the interactive network generates an interactive target resource amount according to a pre-stored interaction ratio between the source application and the target application, and the interactive source resource amount; the node that generates the interactive target resource amount sends second resource interaction information to the node of the application blockchain network belonging to the target application, and the second resource interaction information includes a user identifier and an interactive target resource amount; the node of the application blockchain network belonging to the target application updates the user's resource amount stored in the application blockchain network according to the user identifier and the interactive target resource amount, and feeds back interaction success information to the interactive network; upon receiving an interaction success instruction, the node of the application blockchain network belonging to the source application updates the user's resource amount stored in the application blockchain network to which it belongs according to the interactive source resource amount.

[0139] Such a system can realize resource exchange among users in different application blockchain networks through an interactive network, thereby enabling the circulation and interaction of user resources in different application blockchain networks, reducing the isolation between blockchain networks and improving the flexibility of blockchain networks.

[0140] In some embodiments, the network resource interaction system may further include an interaction server connected to one or more nodes in the interaction network. The interaction server stores a smart contract. The node of the interaction network sends the first resource interaction request to the interaction server, and obtains the interaction target resource amount from the interaction server.

[0141] Such a system can reduce the requirements for node functions and processing capabilities in the interactive network, which is conducive to promotion and application.

[0142] In some embodiments, the network resource interaction system may further include multiple application blockchain networks 42-1 to 42-N, each application blockchain network including multiple nodes (4211 to 421M, 4221 to 422P... 42N1 to 42NQ) and links between nodes, wherein M is the number of nodes in the application blockchain network 42-1, P is the number of nodes in the application blockchain network 42-2, Q is the number of nodes in the application blockchain network 42-N, and M, P, and Q are greater than the predetermined number of nodes that need to be incorporated into the interactive network. In some embodiments, the application corresponding to each application blockchain network needs to establish a smart contract with at least one other application, and the smart contract includes the exchange ratio information of resources between applications. The smart contract is stored in one or more nodes of the interactive network or the interactive server.

[0143] When the application blockchain network is used as the source application of the first resource interaction request, any node of the application blockchain network receives the first resource interaction request from the user and sends it to the node belonging to the interactive network in the current application blockchain network; when a successful interaction instruction for the current application blockchain network is received from the interactive network, the stored user's resource amount is updated according to the interactive source resource amount.

[0144] When the application blockchain network is used as the target application of the first resource interaction request, the second resource interaction information is received by the node belonging to the interactive network in the application blockchain network; according to the user identifier and the interactive target resource quantity, the resource quantity of the user stored in the current application blockchain network is updated, and the interaction success information is fed back to the interactive network.

[0145] In some embodiments, the application corresponding to the application blockchain network can only be used as a source application, can only be used as a target application, or can be used as a source application or a target application as needed.

[0146] Such a system includes multiple application blockchain networks, which can realize the mutual conversion of resources between applications that meet the needs of the application party through smart contracts, making it convenient for users to use, reducing the isolation of application blockchain networks in the system, and improving user experience.

[0148] The selection unit 501 can select a predetermined number of nodes in each application blockchain network according to the paths between the nodes of the application blockchain network and the paths between the nodes of the application blockchain network and the predetermined initial nodes. The predetermined initial nodes are nodes in the interactive network that do not belong to any application blockchain network.

[0149] In some embodiments, node selection can be performed based on the path length between nodes of each application blockchain network and the path length between the application node and the initial node predetermined by the interactive network. In some embodiments, nodes on the path with strong processing capabilities and faster transmission speeds can also be selected based on the computing power of the node, path bandwidth, etc., to improve the performance of the interactive network.

[0150] In some embodiments, the predetermined number may be 1, thereby preventing multiple shared nodes belonging to the same application from receiving and processing requests at the same time. In other embodiments, the predetermined number may be greater than 1, thereby improving the robustness of the system. In some embodiments, priorities may be set for multiple shared nodes of the same application, and nodes with higher priorities may preferentially process requests related to the application to which they belong.

[0151] In some embodiments, the selection unit 501 can select a predetermined number of nodes in each application blockchain network through the operations between steps 301 to 303 above.

[0152] The interactive network acquisition unit 502 can merge the selected nodes and the paths between the nodes into the connection of the initial node, and obtain an interactive network consisting of the initial node, the selected nodes and the paths between the nodes, and the interactive network is a blockchain network.

[0153] Such a system can realize resource exchange among users in different application blockchain networks through an interactive network, thereby enabling the circulation and interaction of user resources in different application blockchain networks, reducing the isolation between blockchain networks and improving the flexibility of blockchain networks.
