All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a block chain network topology according to an embodiment of the present disclosure. As shown in fig. 1, the blockchain network topology may include a transaction node, an arbitration assist node, a consensus node, and the like. For convenience of description, the transaction node, the arbitration auxiliary node, the consensus node, and the like may be collectively referred to as nodes in a blockchain network, where each node has a connection relationship with other nodes. As shown in fig. 1, the number of each type of node may include a plurality of nodes, for example, the transaction nodes may include transaction node 1 and transaction node 2, etc., without limitation. It is to be appreciated that any node in the blockchain network topology can be any form of computing device, such as a server, a terminal, etc., without limitation. It should be understood that the terminal includes, but is not limited to, a mobile phone, a tablet computer, a notebook computer, a palm top computer, a Mobile Internet Device (MID), etc., and is not limited thereto. Each node may receive input information during normal operation and maintain shared data within the blockchain network topology based on the received input information. In order to ensure information intercommunication in the blockchain network topology, information connection can exist between each node in the blockchain network topology, and information transmission can be carried out between the nodes through the information connection. For example, when any node in the blockchain network topology receives input information, other nodes in the blockchain network topology acquire the input information according to a consensus algorithm, and store the input information as data in shared data, so that the data stored on all nodes in the blockchain network topology are consistent.

According to the method in the embodiment of the application, the first transaction node acquires the multiple transaction data between the first transaction node and the second transaction node within the first preset time period, and the second transaction node verifies the validity of the transaction confirmation information of each transaction data in the multiple transaction data according to each transaction data. When the transaction confirmation information of the first transaction data is determined to be illegal transaction confirmation information, the first transaction node can send a transaction verification request for the first transaction data to the arbitration node. The arbitration node receives the transaction verification request, can acquire transaction contract data corresponding to the transaction contract identification from the block chain according to the transaction contract identification included in the transaction verification request, determines the legality of the first transaction data according to the transaction contract data, and sends first transaction confirmation information of the first transaction data to the first transaction node when the first transaction data is determined to be legal transaction data. The first transaction node receives the first transaction confirmation message, and broadcasts the first transaction data and the first transaction confirmation message in the blockchain system, so that each consensus node in the blockchain system checks the first transaction data to generate a check result. And when the first transaction node determines that the consensus nodes agree on the first transaction data according to the received check result sent by the consensus nodes, adding a transaction block comprising the first transaction to the block chain. By adopting the embodiment of the application, the transaction data processing efficiency can be improved, and the block chain resources are saved.

The method and the related apparatus provided by the embodiments of the present application will be described in detail with reference to fig. 2 to 6, respectively.

Referring to fig. 2, fig. 2 is a schematic flow chart of a data processing method according to an embodiment of the present disclosure. The method provided by the embodiment of the application can comprise the following steps S101 to S106:

s101, the first trading node obtains a plurality of trading data between the first trading node and the second trading node within a first preset time period, and the second trading node confirms trading information of each trading data in the plurality of trading data.

In some possible embodiments, the first transaction node may obtain a plurality of transaction data with the second transaction node within a first preset time period, and the second transaction node may obtain transaction confirmation information for each transaction data in the plurality of transaction data. The transactions between the first transaction node and the second transaction node are transactions in which the first transaction node and the second transaction node are both used as participants, such as transfer transactions, red packages and the like, and may be determined based on actual application scenarios, which is not limited herein. The specific value of the first preset time period may also be determined according to an actual application scenario, which is not limited herein.

Generally, the first trading node may determine, from each trading node, a trading node generating the largest trading amount with the first trading node as the second trading node according to the trading amount between the first trading node and each trading node within a second preset time period. That is to say, the first trading node may determine the trading node that trades frequently with itself from other trading nodes as the second trading node by monitoring the trading situation of other trading nodes in the blockchain system with itself within a period of time.

Optionally, in some possible embodiments, when the first trading node monitors that there are trades generated between the first trading node and a certain trading node within N consecutive unit times, the trading node may be determined as the second trading node. The unit time includes, but is not limited to, an hour, a day, a week, and the like, and may be determined based on an actual application scenario, which is not limited herein. N is an integer greater than 2, and a specific value of N may be determined based on an actual application scenario, which is not limited herein.

Optionally, in some possible embodiments, the first transaction node may further determine, as the second transaction node, a transaction node whose historical transaction amount is greater than a preset number threshold by acquiring historical transaction amounts between each other transaction node and the first transaction node in the blockchain system.

S102, the first transaction node verifies the legality of the transaction confirmation information of each transaction data according to each transaction data, and when the transaction confirmation information of the first transaction data is determined to be illegal transaction confirmation information, a transaction verification request for the first transaction data is sent to the arbitration node.

In some possible embodiments, the first transaction node may verify the validity of the transaction confirmation information of the second transaction node for each transaction data according to each transaction data. The transaction data may include data contents such as transaction generation time, transaction amount, transaction participants (i.e., the first transaction node and the second transaction node), transaction routing, and the like. The transaction confirmation information may include a transaction digital signature of the second transaction node on the transaction data, and the like. Therefore, when the first transaction node verifies the validity of the transaction confirmation information of each transaction datum according to each transaction datum, the first transaction node can obtain the node public key of the second transaction node from the block chain, and sequentially decrypt the transaction digital signature of each transaction datum based on the node public key according to the sequence of the transaction generation time from morning to evening to obtain the first summary information. Further, the first transaction node may further perform a hash operation on each transaction data to obtain second summary information corresponding to each transaction data. It should be understood that when the first transaction summary information corresponding to any transaction data (for convenience of description, the first transaction data is taken as an example for explanation) is the same as the second transaction summary information corresponding to the first transaction data, the transaction confirmation information of the first transaction data can be determined to be the legal transaction confirmation information. When the first transaction summary information corresponding to the first transaction data is different from the second transaction summary information corresponding to the first transaction data, the transaction confirmation information of the first transaction data can be determined to be illegal transaction confirmation information.

For example, taking a certain transfer transaction between a first transaction node and a second transaction node as an example, when the first transaction node initiates a transfer transaction to the second transaction node, the first transaction node may generate transaction data corresponding to the transfer transaction, and for convenience of description, the transfer transaction data may be referred to as transfer transaction data for short. The transfer transaction data can include transaction generation time, transfer amount, transfer party, transaction reason and other data contents. It will be understood that the fulfillment of any transaction necessarily requires both parties to approve the transfer transaction data without disagreement. Therefore, in order to ensure the normal operation of the transfer transaction, the first transaction node needs to send a transaction confirmation request including the transfer transaction data to the second transaction node, so that the second transaction node generates transaction confirmation information for the transfer transaction according to the transaction confirmation request to return to the first transaction node.

Generally speaking, after the second node transaction node receives the transaction confirmation request, if the transfer transaction data included in the transaction confirmation request is determined to be correct, the transaction confirmation information of the transfer transaction data can be sent to the first transaction node. The transaction confirmation information may include a transaction digital signature of the second transaction node on the transaction data, and the like. Specifically, the second transaction node may perform a hash operation on the confirmed error-free transfer transaction data based on a hash algorithm to obtain corresponding summary information. And then encrypting the generated summary information by using a node private key of a second transaction node to obtain a transaction digital signature. The second transaction node may then send the transaction confirmation information including the transaction digital signature to the first transaction node. After the first transaction node receives the transaction confirmation information sent by the second transaction node, the first transaction node may obtain a node public key of the second transaction node from the blockchain, and decrypt the transaction digital signature included in the transaction confirmation information based on the node public key of the second transaction node to obtain decrypted summary information (for convenience of description, the first summary information is taken as an example for explanation), and meanwhile, the first transaction node may perform hash operation on the transfer transaction data to obtain the summary information corresponding to the transfer transaction data (for convenience of description, the second summary information is taken as an example for explanation). And comparing and analyzing the first summary information and the second summary information to determine the validity of the transaction confirmation information. Generally speaking, when the first summary information is the same as the second summary information, the transaction confirmation information can be determined to be valid transaction confirmation information, that is, when the first transaction node determines that the transaction confirmation information is the valid transaction confirmation information, it indicates that the second transaction node does not disagree with the account transfer transaction data confirmation, and therefore, the transaction can be normally performed. When the first summary and the second summary information are different, the transaction confirmation information may be determined to be illegal transaction confirmation information. Generally, when the transaction confirmation information is determined to be illegal transaction confirmation information, it may be determined that a default condition exists at the second transaction node. Or, when the first transaction node sends the transaction confirmation request to the second transaction node for multiple times, and the transaction confirmation information returned by the second transaction node based on the transaction confirmation request sent each time is illegal transaction confirmation information, it may be determined that the second transaction node has a default condition. Or, when the transaction digital signature cannot be decrypted based on the node public key of the second transaction node, the transaction confirmation information may also be determined to be illegal transaction confirmation information. Or, when the first transaction node does not receive the transaction confirmation information sent by the second transaction node after time out, it may also be determined that the second transaction node has a default condition.

In some possible embodiments, the first transaction node may apply for intervention by the arbitration node when the transaction confirmation information of the first transaction data is determined to be illegal transaction confirmation information. That is, when the transaction confirmation information of the first transaction data is determined to be illegal transaction confirmation information, the first transaction node may send a transaction verification request for the first transaction data to the arbitration node.

Optionally, in some possible embodiments, when the first transaction node determines that the transaction confirmation information of the first transaction data is illegal transaction confirmation information, the first transaction node may suspend validity verification of the transaction confirmation information of each transaction data after the first transaction data, and broadcast the third transaction data and the transaction confirmation information of the second transaction node to the third transaction data in the blockchain system so that each consensus node in the blockchain system verifies the third transaction, where the third transaction data is the transaction data whose transaction generation time is earlier than the first transaction data and whose transaction generation time difference with the transaction generation time of the first transaction data is the smallest. It is understood that when the first transaction node determines that the respective consensus nodes agree on the third transaction data according to the received check result of the third transaction data sent by the respective consensus nodes, the transaction block including the third transaction data is added to the blockchain. That is, when the first transaction node determines that the transaction confirmation information of the first transaction data is illegal transaction confirmation information, the first transaction node may suspend validity verification of the transaction confirmation information of each other transaction data whose subsequent transaction generation time is later than that of the first transaction data, so as to save computing resources. Meanwhile, the first transaction node may send a transaction data (for convenience of description, referred to as a third transaction data for short) that is closest to the transaction generation time of the first transaction data and is located before the first transaction data to each consensus node in the blockchain system for verification, and link the third transaction data when it is determined that each consensus node agrees with the third transaction data.

For example, please refer to fig. 3, fig. 3 is a schematic diagram of an application scenario of data processing according to an embodiment of the present application. As shown in fig. 3, a total of 1000 transaction data are included in the first preset time period, wherein the transaction data can be respectively recorded as transaction 1, transaction 2, transaction 3, … …, transaction 399, transaction 400, transaction 401, … …, transaction 999 and transaction 1000 according to the sequence of the transaction generation time. In order to ensure normal transaction, the second transaction node needs to perform transaction confirmation on each transaction datum. When the first transaction node verifies the validity of the transaction confirmation information of each transaction datum in sequence according to the transaction generation time, when the 400 th transaction is verified, namely the transaction 400, the transaction confirmation information of the transaction 400 is found to be illegal transaction confirmation information, therefore, the first transaction node terminates the validity verification of the transaction confirmation information of the

subsequent transactions

401, 402, … …, 999 and 1000, and simultaneously, the first transaction node can broadcast the transaction confirmation information of the transaction 399 and the transaction 399 in the block chain system, so that the consensus nodes in the block chain system can verify the transaction validity of the transaction 399, and when the consensus nodes achieve consensus, the transaction 399 is added to the block chain.

S103, the arbitration node receives the transaction verification request, acquires transaction contract data corresponding to the transaction contract identification from the block chain according to the transaction contract identification included in the transaction verification request, determines the legality of the first transaction data according to the transaction contract data, and sends first transaction confirmation information of the first transaction data to the first transaction node when the first transaction data is determined to be legal transaction data.

In some possible embodiments, the arbitration node may obtain, by receiving the transaction verification request, transaction contract data corresponding to the transaction contract identifier from the blockchain according to the transaction contract identifier included in the transaction verification request, and determine validity of the first transaction data according to the transaction contract data. It should be understood that the transaction contract data is contract data which is signed by the first transaction node and the second transaction node in advance and uploaded to the block chain, and the transaction contract data comprises transaction detail information of each transaction which is agreed in advance.

Specifically, the arbitration node may confirm whether the first transaction data is normal by: and acquiring trading contract data corresponding to the trading contract identification from the block chain according to the trading contract identification included in the trading verification request, and judging whether the first trading data is normal or not by verifying whether the data content included in the first trading data is matched with the corresponding data content in the trading contract data or not, namely whether contract conditions are met or not. For example, the arbitration node may verify whether the accounts of both transaction parties are legal, whether the balance of the transferred account supports the transfer amount, and the like, and the specific verification manner may be determined based on an actual application scenario, which is not limited herein.

Optionally, in some possible embodiments, when the arbitration node determines that the first transaction data meets the contract condition in the transaction contract data, in order to make the judgment of the arbitration node more confident, the arbitration node may further forward the transaction verification request to each arbitration auxiliary node associated with the arbitration node, so that each arbitration auxiliary node obtains the transaction contract data corresponding to the transaction contract identifier from the block chain according to the transaction contract identifier included in the transaction verification request, so as to check the validity of the first transaction data according to the transaction contract data, and finally return the generated check result to the arbitration node. The arbitration node receives each verification result sent by each arbitration auxiliary node, and when all the verification results sent by each arbitration auxiliary node are determined to be passed, the arbitration node can finally determine that the first transaction data are legal transaction data.

In some possible embodiments, when the arbitration node determines that the first transaction data is valid transaction data, the arbitration node may send first transaction confirmation information for the first transaction data to the first transaction node. That is, the arbitration node is a node corresponding to a mechanism having public trust, and a transaction confirmed by the arbitration node can be determined as valid transaction data. When the arbitration node determines that the first transaction data is abnormal transaction or illegal transaction data, the transaction verification request of the first transaction node can be rejected or refused.

S104, the first transaction node receives the first transaction confirmation information, and broadcasts the first transaction data and the first transaction confirmation information in the blockchain system so that all the consensus nodes in the blockchain system check the first transaction data to generate a check result.

In some possible embodiments, the first transaction node may broadcast the first transaction data and the first transaction confirmation information in the blockchain system by receiving the first transaction confirmation information, so that each consensus node in the blockchain system checks the first transaction data to generate a check result. That is, when a breach condition exists at the second transaction node, the transaction data validated by the arbitration node may continue to advance.

And S105, when the first transaction node determines that the consensus nodes agree with the first transaction data according to the received check result sent by the consensus nodes, adding a transaction block comprising the first transaction to the block chain.

In some possible embodiments, when the first transaction node determines that the consensus nodes agree on the first transaction data according to the received check result sent by the consensus nodes, the transaction block including the first transaction may be added to the block chain. Specifically, when the check passing proportion in the received check result returned by each consensus node is not less than the preset passing proportion, it can be determined that each consensus node agrees with the first transaction data. For example, when more than 51% of the common nodes in the blockchain system pass the check result, it can be determined that each common node agrees with the first transaction data. Further, a transaction block including the first transaction data may be added to the blockchain.

In some possible embodiments, after adding the transaction block including the first transaction to the blockchain, the first transaction node may continue to validate the transaction confirmation information of each transaction data following the first transaction data, when it is determined that the transaction confirmation information of each transaction data following the first transaction data is all valid transaction confirmation information, determine fourth transaction data with the latest transaction generation time from each transaction data following the first transaction data, and broadcast the fourth transaction data and the transaction confirmation information of the second transaction node to the blockchain system to add the transaction block including the fourth transaction data to the blockchain.

Optionally, in some possible embodiments, the transaction confirmation information of all transaction data in the first preset time period may be obtained at intervals of a first preset time period for validity verification, when the first transaction node determines that the transaction confirmation information of each transaction data in the multiple transaction data in the first preset time period is valid transaction confirmation information, the first transaction node determines the second transaction data with the latest transaction generation time from the multiple transaction data, and broadcasts the second transaction data and the transaction confirmation information of the second transaction data in the blockchain system, so that each consensus node in the blockchain system verifies the second transaction. When the first transaction node determines that the consensus nodes agree with the second transaction data according to the received check result of the second transaction data sent by the consensus nodes, the transaction blocks containing the second transaction data are added to the block chain. That is, when the transaction confirmation information of each transaction data in the first preset time period is the legal transaction confirmation information, the last transaction (i.e., the transaction data with the latest transaction generation time) in the transaction data can be sent to the consensus node in the blockchain network to perform consensus on the transaction. And linking the last transaction within the first predetermined time period when the consensus is achieved. Or when receiving a transaction termination message sent by the first transaction node or the second transaction node, sending the last transaction before the transaction termination message is received to a consensus node in the blockchain network for verification, and after the verification is passed, linking the last transaction. For example, in the process of daily contract-based transactions of A, B, the last transaction is the settlement transaction of A, B, and all the previous transactions are in the form of billing, so that the last transaction of both parties can be linked when A, B terminates the transaction.
