[0038] If a central node fails, it will not only cause the system to crash, but also cause information leakage or tampering, reduce the accuracy of information processing, and affect the user's information security.

[0039] The present application provides a distributed network-based information processing method, device, equipment and storage medium, which are intended to solve the above technical problems in the prior art.

[0040] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0041] Figure 2 This is a flow chart of a distributed network-based information processing method provided in accordance with an embodiment of the present application. At least two network nodes are deployed in the distributed network. The method is applied to electronic devices of the network nodes. The method can be executed by an information processing device based on a distributed network. Figure 2 As shown, the method comprises the following steps:

[0042] S201. Receive encrypted information broadcasted by each network node; wherein the encrypted information is used to represent information generated by each network node by encrypting transaction information sent by itself.

[0043] Exemplarily, a distributed network is constructed by various network nodes involved in a transaction. A network node is a node that sends or receives information during a transaction. Each network node can be represented by an electronic device, and a preset client can be installed in the electronic device to send and receive information. The nodes that interact with information in the distributed network are connected. For example, if transaction information is sent from node A to node B, there is a connection between node A and node B in the distributed network.

[0044] Each network node may receive transaction information. For example, transaction information may include account name, account number, transaction time and amount, etc. Users can enter transaction information through the client to apply for transactions. After receiving the transaction information, the network node on the user side can send the transaction information to the next network node, or process the transaction information and send the processed transaction information to the next network node. The network node link is pre-set during the transaction. The network node link can be used to indicate the node order of information transmission between each network node during the transaction, that is, the next network node of each network node can be determined based on the network node link.

[0045] The first network node that receives the transaction information is determined as the first network node, and the next network node of the first network node is the second network node. After the second network node successfully receives the transaction information or the processed transaction information, the first network node can broadcast the transaction information sent by itself to each network node in the distributed network. The first network node can encrypt the transaction information sent by itself to the second network node to obtain the encrypted information of the transaction information. That is, the encrypted information is the information obtained by each network node encrypting the transaction information sent by itself, and the encrypted information generated by each network node can be different. Each network node broadcasts the encrypted information generated by itself to other network nodes to make the information between each network node consistent. After receiving the transaction information, the second network node processes the transaction information it receives and sends the processed information to its next network node. The next network node of the second network node can be determined as the third network node. After the third network node successfully receives the information, the second network node also encrypts the transaction information sent by itself and broadcasts it to all network nodes. That is, each network node can broadcast encrypted information to other network nodes, and can also receive encrypted information sent by other network nodes. Each network node can also receive transaction information from the previous network node. If the network node is the first network node, the transaction information of the network node is not sent by the previous network node, but is input by the user.

[0046] The network node broadcasts the encrypted information it generates to other network nodes, and the network node itself will also store the generated encrypted information. The network node can receive the encrypted information broadcasted by each network node, and store the received encrypted information in the order in which it is received, thereby determining the transaction process according to the storage order of the encrypted information.

[0047] In this embodiment, the method also includes: receiving transaction information, determining its own next network node based on a preset network node link; sending the transaction information to its own next network node; if feedback information of reception completion is received from the next network node, encrypting the transaction information to obtain encrypted information of the transaction information; broadcasting the encrypted information to each network node of the distributed network.

[0048] Specifically, each network node can send transaction information to its next network node while receiving encrypted information. In this embodiment, the order of steps between each network node receiving encrypted information and sending transaction information is not limited. Each network node receives information sent by the previous network node as its own transaction information. According to the preset network node link, its next network node is determined. Each network node can send the received transaction information to the next network node, or process the received transaction information and send the processed transaction information to the next network node. For example, a preset part of the transaction information can be sent to the next network node. The network node that sends the transaction information can be determined as the current network node.

[0049] After receiving the transaction information, the next network node may provide feedback to the current network node. For example, it may send feedback information of reception completion or transaction completion to the current network node. After receiving the feedback information from the next network node, the current network node encrypts the transaction information, which may be the transaction information sent by itself. In this embodiment, the transaction information received by a network node may be different from the transaction information sent. For example, the transaction information sent is the information processed from the received transaction information. After encrypting the sent transaction information, the current network node obtains the encrypted information corresponding to the sent transaction information, broadcasts the encrypted information to all network nodes in the distributed network, and stores the generated encrypted information itself.

[0050] The beneficial effect of such a setting is that when each network node receives encrypted information broadcast by other network nodes, each network node can also receive transaction information and send the transaction information to the next network node. If the next network node successfully receives or processes the transaction information, the network node can encrypt the transaction information and broadcast the encrypted information, thereby avoiding malicious interception and tampering of transaction information during broadcast, thereby improving the security of information interaction.

[0051] In this embodiment, the transaction information is encrypted to obtain the encrypted information of the transaction information, including: performing hash calculation on at least one transaction information according to a preset hash algorithm to obtain the hash value of each transaction information; sorting the hash values ​​corresponding to each transaction information according to the field arrangement order of the transaction information to obtain a hash string; performing hash calculation on the hash string to obtain the encrypted information corresponding to the transaction information.

[0052] Specifically, when a network node sends a transaction message, it may send multiple transaction messages to the next network node, that is, multiple transaction messages may be sent each time. For example, transaction information such as account name, account number, transaction time and amount may be sent. An encryption algorithm is preset, for example, the encryption algorithm may be a hash algorithm. According to the preset encryption algorithm, each transaction message sent is encrypted. For example, each transaction message may be hashed to obtain a hash value corresponding to each transaction message.

[0053] When a network node sends out transaction information, each piece of transaction information is arranged in order. For example, the field arrangement order of the transaction information can be preset, and the field can represent the name of each transaction information. For example, the preset field arrangement order can be account name, account number, transaction time, and amount. After obtaining the hash value of each transaction information, the hash value of each transaction information is arranged into a string according to the preset field arrangement order to obtain a hash string. For example, taking a 32-bit hash value as an example, four hash values ​​of length 32 are obtained according to the four fields of account name, account number, transaction time, and amount, and a hash string of length 128 is obtained by splicing according to the field order. After obtaining the hash string, the hash string is hashed again to obtain the hash value of the hash string, which is used as the encrypted information corresponding to the transaction information sent by the network node, and the encrypted information is broadcast to each network node.

[0054] The beneficial effect of this arrangement is that encryption is performed according to the hash algorithm, which makes the encryption irreversible and prevents the encrypted information from being cracked. Performing two hash calculations further prevents the encrypted information from being tampered with, effectively improving the security of the information.

[0055] S202: According to a preset data packaging cycle, determine a target node from each network node of the distributed network.

[0056] Exemplarily, a data packaging cycle is pre-set, for example, the data packaging cycle can be five minutes. Every other data packaging cycle, a network node can be determined from each network node of the distributed network as a target node, and the target node can package the encrypted information generated or received during the data packaging cycle.

[0057] The target node determination rule may be pre-set, and the target node may be determined according to the target node determination rule. For example, the target node determination rule may be that each network node serves as a target node in turn. Every other data packaging cycle, each network node may determine whether it is its turn to serve as a target node. If it is not a network node, it does not need to package the encrypted data.

[0058] By determining the target node, there is no need to set up a central node, and the target node is not fixed, which reduces the performance pressure and security impact of the central node on the stable operation of the entire system. It avoids data loss or downtime at the central node, which may cause the entire system to be paralyzed and lose service capabilities, and effectively improves the stability of transactions.

[0059] S203: If it is determined that it is the target node, the encrypted information obtained by itself during the data packaging cycle is sent to the network node that broadcasts the encrypted information, so that the network node that broadcasts the encrypted information verifies the broadcasted encrypted information and feeds back the verification result to the target node.

[0060] For example, if it is a target node, it will send the encrypted information received by itself in the data packaging cycle to the network nodes that broadcast the encrypted information at that time. The encrypted information obtained in the data packaging cycle closest to the current time can be sent to the corresponding network node. Not all network nodes need to receive the encrypted information in the data packaging cycle, and each encrypted information in the data packaging cycle is sent to a corresponding network node.

[0061] The network node that receives the encrypted information sent by the target node is the network node that sends the encrypted information to the target node during the data packaging cycle. For example, the target node is node A, and there are nodes A, B, C, and D in the distributed network. During the data packaging cycle, node A receives the encrypted information broadcast by node B as encrypted information 1, and also receives the encrypted information broadcast by node C as encrypted information 2. When node A sends the encrypted information to the corresponding network node, it sends encrypted information 1 to node B and encrypted information 2 to node C, and does not need to send encrypted information to node D.

[0062] After receiving the encrypted information sent by the target node, each network node obtains the information stored when sending the encrypted information to the target node. The stored information is the information generated by encrypting the transaction information. If there is no data loss or tampering when each network node sends the encrypted information to the target node, the stored information should be consistent with the encrypted information sent by the target node; if there is data loss or tampering when each network node sends the encrypted information to the target node, the stored information is inconsistent with the encrypted information sent by the target node. Therefore, after receiving the encrypted information, each network node can verify the received encrypted information. For example, the received encrypted information can be compared with the corresponding stored information. If the two are consistent, the verification result of the encrypted information is determined to be passed; if the two are inconsistent, the verification result of the encrypted information is determined to be failed. After obtaining the verification result of the encrypted information, each network node can feedback the verification result to the target node.

[0063] S204: If the verification result fed back by the network node receiving each broadcast encrypted information is verification passed, the encrypted information that has passed the verification within the data packaging cycle is packaged, and the packaged encrypted information is sent to each network node of the distributed network.

[0064] Exemplarily, the target node receives the verification results of each network node. If each verification result is verified, it is determined that the encrypted information has not been tampered with during the broadcast, and the transaction information represented by the encrypted information is correct transaction information. The target node can package all the encrypted information that has passed the verification within the data packaging cycle, and send the packaged encrypted information to each network node of the distributed network. All encrypted information within the data packaging cycle includes the encrypted information received from each network node within the data packaging cycle, and may also include the encrypted information generated by the target node itself. After receiving the data packet of the encrypted information, each network node deletes each piece of encrypted information within the data packaging cycle, that is, each network node can replace the encrypted information within the data packaging cycle with a data packet.

[0065] If the verification result is that the verification fails, or there is a network node that does not feedback the verification result within the preset time period after receiving the encrypted information sent by the target node, the encrypted information that fails the verification will be discarded, or the encrypted information corresponding to the verification result that is not fed back will be discarded. The encrypted information that passes the verification will be packaged into a data packet and sent to each network node. After receiving the data packet, each network node discards all encrypted information within the data collection cycle.

[0066] The embodiment of the present application provides an information processing method based on a distributed network, in which the network nodes in the distributed network receive the encrypted information broadcast by each network node, and the encrypted information is obtained by each network node encrypting the transaction information to be sent by itself. That is, each network node can encrypt the transaction information sent and broadcast the encrypted information to other network nodes, and can also receive the encrypted information broadcast by each network node. The network node determines a target node at a fixed time, and the target node sends the encrypted information within a period of time to the corresponding network node respectively, and the corresponding network node is the network node that broadcasts the encrypted information to the target node. The network node verifies the corresponding encrypted information. If the verification is passed, the target node packages the encrypted information and broadcasts it to each network node after packaging. The problem of network instability caused by information broadcasting by a preset central node in the prior art is solved. By flexibly determining the target node, the stability of the network during information processing is improved. By encrypting and verifying the information, the security of the information can be ensured, the information can be prevented from being maliciously tampered with during the information transmission process, and the accuracy and efficiency of information processing can be improved.

[0067] Figure 3 A flow chart of a distributed network-based information processing method provided in an embodiment of the present application is an optional embodiment based on the above-mentioned embodiment.

[0068] In this embodiment, according to a preset data packaging cycle, a target node is determined from each network node of the distributed network, which can be further refined as follows: according to the preset data packaging cycle, the network nodes in the distributed network are voted to determine the number of votes of each network node; according to the number of votes of each network node, based on a preset target node determination rule, a target node is determined from each network node.

[0069] like Figure 3 The method comprises the following steps:

[0070] S301. Receive encrypted information broadcasted by each network node; wherein the encrypted information is used to represent information generated by each network node by encrypting transaction information sent by itself.

[0071] Exemplarily, this step may refer to the above-mentioned step S201 and will not be described in detail.

[0072] S302: Voting is performed on the network nodes in the distributed network according to a preset data packaging cycle to determine the number of votes obtained by each network node.

[0073] For example, the target node can be determined by voting by each network node. Each network node votes once every data packaging rule. Each network node can be preset with an election counter, which is used to count its own votes. Voting rules can be preset, for example, each network node can vote for three network nodes or only one network node at a time.

[0074] In this embodiment, voting on the network nodes in the distributed network includes: selecting a network node from the network nodes of the distributed network according to a preset random selection algorithm, and voting on the selected network node.

[0075] Specifically, a random selection algorithm is pre-set, and each network node selects a network node based on the random selection algorithm and votes for the selected network node. Each network node in the distributed network selects a network node based on the random selection algorithm, and each network node records its own number of votes. For example, there are nodes A, B, C, D, and E in the distributed network. After a data packaging cycle, each network node randomly selects a network node, node A selects node B, node B selects node E, node C selects node B, node D selects node A, and node E selects node B, that is, node A has one vote, node B has three votes, node C has zero votes, node D has zero votes, and node E has one vote.

[0076] The beneficial effect of this setting is that through the random selection algorithm, network nodes can be quickly selected for voting, and the voting efficiency is high. In addition, the random selection algorithm has fewer calculation processes, which greatly saves the overall system resource consumption of the distributed network.

[0077] S303: Determine a target node from the network nodes according to the number of votes obtained by each network node and based on a preset target node determination rule.

[0078] Exemplarily, after obtaining the number of votes of each network node, the target node is determined from each network node, that is, each network node can determine whether it is a target node according to the number of votes. Each network node can share its own number of votes, and sort the number of votes of all network nodes. According to the preset target node determination rule, a target node is selected. For example, the target node determination rule can be to sort the number of votes from large to small, and determine the first network node, that is, the network node with the highest number of votes, as the target node.

[0079] In this embodiment, after determining a target node from each network node of the distributed network according to a preset data packaging cycle, it also includes: if it is determined that itself is not the target node, receiving encrypted information sent by the target node; determining the transaction information corresponding to the encrypted information, and obtaining the pre-stored information generated by encrypting the transaction information; comparing the encrypted information with the information generated by encrypting the transaction information, if the encrypted information is consistent with the information generated by encrypting the transaction information, determining that the verification result of the encrypted information is verified, and feeding back the verification result to the target node.

[0080] Specifically, if it is determined that its own network node is not the target node, then the target node is determined to be another network node, and the target node sends the encrypted information obtained during the data packaging cycle to the network node that broadcasts the encrypted information.

[0081] A network node that is not a target node can receive encrypted information sent by a target node. The encrypted information sent by the target node is the encrypted information broadcasted to the target node. When broadcasting, the network node encrypts the transaction information and broadcasts the encrypted information to each network node.

[0082] After receiving the encrypted information sent by the target node, the information corresponding to the encrypted information is searched. The information corresponding to the encrypted information can be the corresponding transaction information, or it can be the information generated by encrypting the received transaction information before broadcasting the encrypted information. The transaction information and the information generated by the encrypted transaction information can be stored in association. The transaction information corresponding to the encrypted information is determined, and then the information generated by encrypting the transaction information is obtained. The encrypted information sent by the target node and the information generated by encrypting the corresponding transaction information are compared. If the two are consistent, it is determined that the encrypted information has not been destroyed during the broadcast process, and the verification result of the encrypted information is verification passed; if the two are inconsistent, it is determined that the encrypted information has been lost or tampered with during the broadcast process, and the verification result of the encrypted information is verification failed. Regardless of whether the verification result is verification passed or verification failed, the network node that receives the encrypted information sent by the target node can feed back the verification result to the target node.

[0083] The beneficial effect of this setting is that the encrypted information is a string of hash characters. Hash encryption is an irreversible process that can prevent information leakage, and by comparing the character strings, the verification efficiency can be improved. Through the hash information anti-counterfeiting verification technology, the authenticity and accuracy of the information can be ensured, tampering can be prevented, and security can be improved.

[0084] S304: If it is determined that it is the target node, the encrypted information obtained by itself during the data packaging cycle is sent to the network node that broadcasts the encrypted information, so that the network node that broadcasts the encrypted information verifies the broadcasted encrypted information and feeds back the verification result to the target node.

[0085] Exemplarily, this step may refer to the above-mentioned step S203 and will not be described in detail.

[0086] S305: If the verification result fed back by the network node receiving each broadcast encrypted information is verification passed, the encrypted information that has passed the verification within the data packaging cycle is packaged, and the packaged encrypted information is sent to each network node of the distributed network.

[0087] Exemplarily, this step may refer to the above-mentioned step S204 and will not be described in detail.

[0088] The embodiment of the present application provides an information processing method based on a distributed network, in which the network nodes in the distributed network receive the encrypted information broadcast by each network node, and the encrypted information is obtained by each network node encrypting the transaction information to be sent by itself. That is, each network node can encrypt the transaction information sent and broadcast the encrypted information to other network nodes, and can also receive the encrypted information broadcast by each network node. The network node determines a target node at a fixed time, and the target node sends the encrypted information within a period of time to the corresponding network node respectively, and the corresponding network node is the network node that broadcasts the encrypted information to the target node. The network node verifies the corresponding encrypted information. If the verification is passed, the target node packages the encrypted information and broadcasts it to each network node after packaging. The problem of network instability caused by information broadcasting by a preset central node in the prior art is solved. By flexibly determining the target node, the stability of the network during information processing is improved. By encrypting and verifying the information, the security of the information can be ensured, the information can be prevented from being maliciously tampered with during the information transmission process, and the accuracy and efficiency of information processing can be improved.
