The methods and related apparatuses provided by the embodiments of the present application will be described in detail below with reference to FIG. 2 to FIG. 6 respectively.

Please refer to FIG. 2, which is a schematic flowchart of a data processing method provided by an embodiment of the present application. The method provided by this embodiment of the present application may include the following steps S101 to S106.

S101. The first transaction node acquires multiple transaction data with the second transaction node within the first preset time period, and transaction confirmation information of the second transaction node for each transaction data in the multiple transaction data.

In some feasible implementations, the first transaction node may obtain multiple transaction data between the first transaction node and the second transaction node within the first preset time period, and the transaction data of each transaction data in the multiple transaction data by the second transaction node Confirm the information. Among them, the transaction between the first transaction node and the second transaction node is a transaction in which both the first transaction node and the second transaction node are participants, such as transfer transactions, red envelopes, etc., which can be determined based on actual application scenarios. Here No restrictions. 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 speaking, the first transaction node can determine the transaction node with the largest number of transactions with the first transaction node from the transaction nodes according to the number of transactions between the first transaction node and each transaction node within the second preset time period , as the second transaction node. That is to say, the first transaction node can monitor the transactions between other transaction nodes in the blockchain system with itself within a period of time, and then determine the transaction node that frequently trades with itself as the second transaction from the other transaction nodes. node.

Optionally, in some feasible implementation manners, when the first transaction node monitors that there are transactions occurring between the first transaction node and a certain transaction node for N consecutive units of time, the transaction node may be determined as the transaction node. The second transaction node. The above-mentioned unit time includes but is not limited to one hour, one day, one week, etc., which may be determined based on actual application scenarios, and is not limited here. Wherein, N is an integer greater than 2, and the specific value of N can be determined based on the actual application scenario, which is not limited here.

Optionally, in some feasible implementations, the first transaction node can also obtain the historical transaction volume between other transaction nodes in the blockchain system and the first transaction node, and set the historical transaction volume to be greater than the preset number threshold. The transaction node is determined as the second transaction node.

S102. The first transaction node verifies the validity of the transaction confirmation information of each transaction data according to each transaction data, and when it is determined that the transaction confirmation information of the first transaction data is illegal transaction confirmation information, it sends the first transaction confirmation information to the arbitration node. Transaction verification request for data.

In some feasible implementations, the first transaction node can verify the legitimacy of the transaction confirmation information of each transaction data by the second transaction node according to each transaction data. The transaction data may include transaction generation time, transaction amount, transaction participants (ie, the first transaction node and the second transaction node), transaction reasons, and other data content. The transaction confirmation information may include a transaction digital signature of the transaction data by the second transaction node, and the like. Therefore, when the first transaction node verifies the legitimacy of the transaction confirmation information of each transaction data according to each transaction data, the first transaction node can obtain the node public key of the second transaction node from the blockchain, and according to the transaction In the order of generation time from early to late, the transaction digital signature of each transaction data is decrypted in turn based on the node public key to obtain the first digest 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 is not difficult to understand that, when the first transaction summary information corresponding to any transaction data (for the convenience of description, the first transaction data is taken as an example for description) is the same as the second summary information corresponding to the first transaction data, it can be determined. The transaction confirmation information of the first transaction data is legal transaction confirmation information. When the first transaction summary information corresponding to the first transaction data is different from the second summary information corresponding to the first transaction data, it may be determined that the transaction confirmation information of the first transaction data is illegal transaction confirmation information.

For example, taking a transfer transaction between the first transaction node and the second transaction node as an example, when the first transaction node initiates a transfer transaction to the second transaction node, the first transaction node can generate a corresponding transfer transaction for the transfer transaction. For the convenience of description, the transaction data may be referred to as transfer transaction data. The transfer transaction data may include data content such as transaction generation time, transfer amount, transfer-in party, transfer-out party, and transaction reasons. It is not difficult to understand that the conclusion of any transaction must require both parties to the transaction to recognize and have no objection to the transfer transaction data. Therefore, in order to ensure the normal progress 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 the transfer according to the transaction confirmation request. The transaction confirmation information of the transaction is returned to the first transaction node.

Generally speaking, after receiving the transaction confirmation request, the transaction node of the second node can send the transaction confirmation information of the transfer transaction data to the first transaction node if it is determined that the transfer transaction data included in the transaction confirmation request is correct. Wherein, the above-mentioned transaction confirmation information may include a transaction digital signature of the transaction data of the second transaction node, and the like. Specifically, the second transaction node may perform a hash operation on the confirmed transfer transaction data based on a hash algorithm to obtain corresponding summary information. The generated digest information is encrypted by the node private key of the second transaction node, and a transaction digital signature can be obtained. Then, the second transaction node may send transaction confirmation information including the transaction digital signature to the first transaction node. Wherein, after the first transaction node receives the transaction confirmation information sent by the second transaction node, the first transaction node can obtain the node public key of the second transaction node from the blockchain, and based on the node public key of the second transaction node Decrypt the transaction digital signature included in the transaction confirmation information to obtain the decrypted summary information (for the convenience of description, the first summary information is taken as an example), and at the same time, the first transaction node performs hashing on the transfer transaction data. Then, the summary information corresponding to the transfer transaction data can be obtained (for the convenience of description, the second summary information is taken as an example for description). Furthermore, by comparing and analyzing the first summary information and the second summary information, the legitimacy of the transaction confirmation information can be determined. Generally speaking, when the first summary information is the same as the second summary information, it can be determined that the transaction confirmation information is legal transaction confirmation information. That is, when the first transaction node determines that the transaction confirmation information is legal transaction confirmation information, the The second transaction node has no objection to the confirmation of the transfer transaction data, so the transaction can proceed normally. 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 speaking, when it is determined that the transaction confirmation information is illegal transaction confirmation information, it can be determined that the second transaction node has a default situation. Alternatively, when the first transaction node sends transaction confirmation requests to the second transaction node for many times, and the transaction confirmation information returned by the second transaction node based on each transaction confirmation request sent is illegal transaction confirmation information, it can be determined that the The second transaction node is in breach of contract. Alternatively, when the transaction digital signature cannot be decrypted based on the node public key of the second transaction node, the transaction confirmation information can also be determined to be illegal transaction confirmation information. Alternatively, when the first transaction node fails to receive the transaction confirmation information sent by the second transaction node within the timeout period, it may also be determined that the second transaction node is in breach of contract.

In some feasible implementations, when it is determined that the transaction confirmation information of the first transaction data is illegal transaction confirmation information, the first transaction node may apply for the intervention of the arbitration node. That is, when it is determined that the transaction confirmation information of the first transaction data is 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 feasible implementation manners, 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 each transaction after the first transaction data. The legality of the transaction confirmation information of the data is verified, and the third transaction data and the transaction confirmation information of the second transaction node for the third transaction data are broadcast in the blockchain system, so that each consensus node in the blockchain system can verify the third transaction data. Three transactions are verified, wherein the third transaction data is transaction data whose transaction generation time is earlier than that of the first transaction data, and the transaction generation time difference between the transaction generation time of the first transaction data and the transaction generation time of the first transaction data is the smallest. It is not difficult to understand that when the first transaction node determines that each consensus node has reached a consensus on the third transaction data according to the received verification results of the third transaction data sent by each consensus node, the transaction including the third transaction data will be Blocks are added to the blockchain. That is to say, 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 can suspend the transactions of other transaction data whose subsequent transaction generation time is later than that of the first transaction data. Confirm the validity of information to save computing resources. At the same time, the first transaction node can send a transaction data (for the convenience of description, referred to as the third transaction data) that is closest to the transaction generation time of the first transaction data and located before the first transaction data to the zone Each consensus node in the blockchain system performs verification, and when it is determined that each consensus node has reached a consensus on the third transaction data, the third transaction data is uploaded to the chain.

For example, please refer to FIG. 3 , which is a schematic diagram of an application scenario of data processing provided by an embodiment of the present application. As shown in Figure 3, the first preset time period includes a total of 1000 transaction data, among which, according to the order of transaction generation time, they can be recorded as transaction 1, transaction 2, transaction 3, ..., transaction 399, Transaction 400, Transaction 401, ..., Transaction 999, Transaction 1000. Among them, in order to ensure the normal progress of the transaction, the second transaction node needs to perform transaction confirmation on each transaction data. Among them, when the first transaction node sequentially verifies the validity of the transaction confirmation information of each transaction data according to the transaction generation time, when the 400th transaction is verified, that is, transaction 400, it is found that the transaction confirmation information of transaction 400 is invalid. Legal transaction confirmation information, therefore, the first transaction node will terminate the legality verification of the subsequent transaction 401, transaction 402,... The confirmation information and the transaction 399 are broadcast in the blockchain system, so that the consensus nodes in the blockchain system can verify the transaction legality of the transaction 399, and when each consensus node reaches a consensus, the transaction 399 is added to the block chain.

S103. The arbitration node receives the transaction verification request, obtains the 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 determines the legality of the first transaction data according to the transaction contract data. When determining that the first transaction data is legal transaction data, the arbitration node sends first transaction confirmation information for the first transaction data to the first transaction node.

In some feasible implementations, by receiving the transaction verification request, the arbitration node can obtain the 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 the first order according to the transaction contract data. 1. Legality of transaction data. It should be understood that the above-mentioned transaction contract data is the contract data signed in advance by the first transaction node and the second transaction node and uploaded to the blockchain, and the transaction contract data includes the transaction details of each transaction agreed in advance.

Specifically, the arbitration node can confirm whether the first transaction data is normal in the following manner: according to the transaction contract identifier included in the transaction verification request, obtain the transaction contract data corresponding to the transaction contract identifier from the blockchain, and verify the first transaction data by Whether the included data content matches the corresponding data content in the transaction contract data to determine whether the first transaction data is normal, that is, whether the contract conditions are met. For example, the arbitration node can verify whether the accounts of both parties of the transaction are legal, and whether the balance of the outgoing account supports the transfer amount, etc. The specific verification method can be determined based on the actual application scenario, which is not limited here.

Optionally, in some feasible implementations, when the arbitration node determines that the first transaction data satisfies the contract conditions in the transaction contract data, in order to make the judgment of the arbitration node more credible, the arbitration node may also 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 blockchain according to the transaction contract identifier included in the transaction verification request, so as to verify according to the transaction contract data The validity of the first transaction data, and finally return the generated verification result to the arbitration node. The arbitration node receives each verification result sent by each arbitration auxiliary node, and when it is determined that each verification result sent by each arbitration auxiliary node is all verified, the arbitration node can finally determine that the first transaction data is legal transaction data.

In some feasible implementation manners, when the arbitration node determines that the first transaction data is legal transaction data, the arbitration node may send first transaction confirmation information for the first transaction data to the first transaction node. That is to say, the arbitration node, as a node corresponding to a credible institution, can determine the transaction confirmed by the arbitration node as legal transaction data. Wherein, when the arbitration node determines that the first transaction data is abnormal transaction or illegal transaction data, it can reject or reject the transaction verification request of the first transaction node.

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 each consensus node in the blockchain system performs the first transaction data on the first transaction data. Verify to generate verification results.

In some feasible implementations, 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 in the blockchain system can be achieved. The node verifies the first transaction data to generate a verification result. That is to say, when the second transaction node is in breach of contract, the transaction data confirmed by the arbitration node can continue to advance.

S105. When the first transaction node determines that each consensus node has reached a consensus on the first transaction data according to the received verification results sent by each consensus node, add a transaction block including the first transaction to the blockchain.

In some feasible implementations, when the first transaction node determines that each consensus node has reached a consensus on the first transaction data according to the received verification results sent by each consensus node, the transaction block including the first transaction can be added to the blockchain. Specifically, when the proportion of the verification results returned by the received consensus nodes is not less than the preset pass ratio, it can be determined that each consensus node has reached a consensus on the first transaction data. For example, when the verification results of more than 51% of the consensus nodes in the blockchain system are verified, it can be determined that each consensus node has reached a consensus on the first transaction data. Further, the transaction block including the first transaction data can be added to the blockchain.

In some feasible implementations, after adding the transaction block including the first transaction to the blockchain, the first transaction node can continue to verify the legitimacy of the transaction confirmation information of each transaction data after the first transaction data , when it is determined that the transaction confirmation information of each transaction data after the first transaction data is all legal transaction confirmation information, the fourth transaction data with the latest transaction generation time is determined from each transaction data after the first transaction data, The fourth transaction data and the transaction confirmation information of the second transaction node for the fourth transaction data are broadcast in the blockchain system, so as to add the transaction block including the fourth transaction data to the blockchain.

Optionally, in some feasible implementations, the transaction confirmation information of all transaction data within the first preset time period may be obtained for legality verification at every first preset time period. When the first transaction node When it is determined that the transaction confirmation information of each transaction data in the multiple transaction data within the first preset time period is legal transaction confirmation information, the first transaction node determines the second transaction generation time from the multiple transaction data. transaction data, and broadcast the second transaction data and the transaction confirmation information of the second transaction node to the second transaction data in the blockchain system, so that each consensus node in the blockchain system can verify the second transaction . Wherein, when the first transaction node determines that each consensus node has reached a consensus on the second transaction data according to the received verification result of the second transaction data sent by each consensus node, the transaction block including the second transaction data is added to the transaction block. to the blockchain. That is to say, when the transaction confirmation information of each transaction data within the first preset time period is legal transaction confirmation information, the last transaction in the multiple transaction data (that is, the transaction with the latest transaction generation time) can be data) to consensus nodes in the blockchain network to reach consensus on the transaction.
