In one embodiment, as shown in fig. 2, a method for processing blockchain transaction data is provided, which is described by taking the method as an example applied to the first endorsement node 102 in fig. 1, and includes the following steps:
Step 202, a first endorsement node in the blockchain system receives the transaction data, and performs a first endorsement operation according to the transaction data to obtain a first endorsement result.
Specifically, the transaction data may be transaction data that needs to be linked and is sent by a transaction sender (a transaction client on the blockchain) to the blockchain, when the transaction data is successfully linked, the transaction is successfully ended, the first endorsement node is a node in the blockchain system and used for verifying whether the transaction data is legal, and the first endorsement result is a verification result of the first endorsement node for verifying the transaction data. And after the first endorsement node in the block chain system receives the transaction data, performing a first endorsement operation on the transaction data to obtain a corresponding first endorsement result. In addition, the endorsement operation of the endorsement node in the blockchain is used for verifying whether the data is legal, for example, the endorsement operation of the first endorsement node is used for verifying whether the received transaction data is legal.
And 204, the first endorsement node acquires a preset endorsement strategy, acquires a corresponding second endorsement node according to the endorsement strategy, and sends transaction data to the second endorsement node.
Specifically, the second endorsement node is an endorsement node that needs to verify the validity of the transaction data in addition to the first endorsement node. The endorsement strategy is used for guiding the endorsement node to carry out correct endorsement, and can also obtain other second endorsement nodes needing to carry out endorsement operation on transaction data besides the first endorsement node. And the first endorsement node acquires the information of the second endorsement node through the acquired preset endorsement strategy, and sends the transaction data to the second endorsement node for the second endorsement node to perform second endorsement operation on the transaction data.
And step 206, the first endorsement node receives a second endorsement operation performed by the second endorsement node according to the transaction data, and obtains a second endorsement result.
specifically, after the second endorsement node receives the transaction data, the second endorsement operation is performed on the transaction data to obtain a corresponding second endorsement result, the second endorsement result is fed back to the first endorsement node, and the first endorsement node receives the second endorsement result fed back by the second endorsement node.
And step 208, the first endorsement node obtains a target endorsement result according to the first endorsement result and the second endorsement result.
specifically, after receiving a second endorsement result fed back by a second endorsement node, the first endorsement node integrates the first endorsement result and the second endorsement result to obtain an integrated target endorsement result, and packages the first endorsement result and the second endorsement node, so that the target endorsement result is conveniently verified subsequently.
And step 210, the first endorsement node verifies the target endorsement result, and when the target endorsement result passes the verification, the target endorsement result is sent to the consensus node.
Specifically, the first endorsement node verifies the target endorsement result, and verifies whether the target endorsement result is successful, for example, whether the endorsement result of each endorsement node corresponding to the target endorsement result is successful, that is, whether the data information corresponding to the endorsement result is legal is checked, and when each endorsement node in the target endorsement result passes the verification, and the target endorsement result is sent to the consensus node.
in step 212, the first endorsement node receives the block sorting and dividing performed by the consensus node according to the target endorsement result to obtain a sorting and dividing result, and generates a transaction block corresponding to the transaction data according to the sorting and dividing result.
specifically, after the first endorsement node sends the verified target endorsement result to the consensus node, the consensus node can perform block sorting and division according to transaction data in the target endorsement result, the block sorting and division method can be a quick sorting method commonly used in a block chain, the quick sorting method belongs to an improved algorithm of bubble sorting, and the method is suitable for a block chain network, and after sorting and division, the obtained block sorting and division result is sent to the first endorsement node, so that the first endorsement node and other nodes generate transaction blocks corresponding to the transaction data according to the block sorting and division result, and the transaction data chaining operation is completed.
In the block chain transaction data processing method, after a first endorsement node in a block chain system receives transaction data, first endorsement operation is performed according to the transaction data to obtain a first endorsement result corresponding to the first endorsement operation; acquiring a preset endorsement strategy, acquiring a second endorsement node according to the endorsement strategy, and sending transaction data to the second endorsement node; the first endorsement node receives a second endorsement result obtained by performing a second endorsement operation according to the transaction data through the second endorsement node; obtaining a target endorsement result according to the first endorsement result and the second endorsement result; the first endorsement node verifies the target endorsement result, and when the target endorsement result passes the verification, the target endorsement result is sent to the consensus node for subsequent sequencing and dividing operation; the first endorsement node receives the ordering and division of the blocks performed by the consensus node according to the target endorsement result, obtains an ordering and division result, and generates transaction blocks corresponding to the transaction data according to the ordering and division result. The block chain transaction is completed through the information transmission between the first endorsement node and the second endorsement node and the consensus node, and compared with the traditional method for transmitting the information between the transaction server and the nodes, the method reduces network call and saves resources.
in an embodiment, as shown in fig. 3, in the method for processing blockchain transaction data, after the first endorsement node receives the transaction data, the method may further include:
Step 302, the first endorsement node detects a transaction processing type corresponding to the transaction data.
Specifically, the transaction processing type may be a request type when a transaction sender corresponding to the transaction data sends a transaction request, and the request type may be, for example, a synchronous request, an asynchronous request, or the like. After receiving the transaction data, the first endorsement node in the block chain detects the transaction processing type of the transaction data according to the identification of the transaction type contained in the transaction data, and performs subsequent operation according to the transaction processing type.
And 304, when the transaction processing type is asynchronous transaction, after the target endorsement result is sent to the consensus node, the first endorsement node acquires a transaction sending terminal corresponding to the transaction data, and sends a prompt message that the transaction data is submitted to the transaction sending terminal.
Specifically, when the transaction processing type is asynchronous transaction, it is indicated that the transaction request corresponding to the asynchronous transaction is an asynchronous request, and further, when the transaction request is an asynchronous request, the transaction sending does not need to wait for the result return of the asynchronous request after sending the request, and the next request can be directly sent. When the first endorsement node detects that the transaction processing type corresponding to the transaction data is an asynchronous request, the first endorsement node sends the target endorsement result to the consensus node, and at this time, the target endorsement result is verified, the first endorsement node acquires the address of the transaction sending terminal, sends the transaction data submitted to the transaction sending terminal, and waits for the prompt message generated by the block.
step 306, receiving the query information corresponding to the transaction data sent by the transaction sending terminal, extracting the data identifier contained in the transaction data, querying the state identifier corresponding to the transaction data according to the data identifier, and sending the state identifier to the transaction sending terminal.
Specifically, the data identifier may be a transaction serial number of a transaction request corresponding to the transaction data, and a state identifier corresponding to the transaction data and displaying a current state of the transaction data may be acquired through the transaction serial number, where the state identifier may represent the current state of the transaction data, and may specifically be: the inquiry information is inquiry information which is sent by the transaction sending terminal and corresponds to the transaction data and is required to acquire the state of the transaction data after the first endorsement node sends the information that the transaction data is submitted to the transaction sending terminal. After receiving query information sent by the transaction sending terminal, the first endorsement node extracts a data identifier in the submitted transaction data, and after acquiring the state identifier, the first endorsement node sends the state identifier to the transaction sending terminal so that a transaction user corresponding to the transaction data can know the transaction state.
In the block chain transaction data processing method, the first endorsement node detects the transaction processing type corresponding to the transaction data, and when the transaction processing type is asynchronous transaction, sends the transaction data submission information to the transaction sending terminal after the target endorsement result is verified, and obtains the state identifier and sends the state identifier to the transaction sending terminal after receiving the query information of the transaction sending terminal, so that the transaction sending terminal can know the transaction state.
In one embodiment, in the method for processing blockchain transaction data, after the first endorsement node receives the transaction data, the method may further include: the first endorsement node detects a transaction processing type corresponding to the data; when the transaction processing type is synchronous transaction, after generating a transaction block corresponding to the transaction data according to the sorting and dividing result, the method further comprises the following steps: and the first endorsement node acquires a transaction sending terminal corresponding to the transaction data and sends information that the block generation is successful to the transaction sending terminal.
Specifically, the transaction processing type may be a request type when a transaction sender corresponding to the transaction data sends a transaction request, and the request type may be, for example, a synchronous request, an asynchronous request, or the like. After receiving transaction data, a first endorsement node in the block chain detects a transaction processing type of the transaction data, when the transaction processing type is synchronous transaction, the transaction request corresponding to the synchronous transaction is indicated as synchronous request, further, when the transaction request is synchronous request, a transaction sending terminal can send the next request only after waiting for the result of the synchronous request to return after sending the request, when the first endorsement node detects that the transaction processing type corresponding to the transaction data is synchronous request, after generating a transaction block, the transaction block indicates that the entry of the transaction data is successful, the transaction is successfully ended, the first endorsement node acquires the address of the transaction sending terminal, and sends the block generation success to the transaction sending terminal, namely, the information of the successful end of the transaction, so as to remind a user corresponding to the transaction data that the transaction is successfully ended.
In this embodiment, the first endorsement node detects the transaction processing type corresponding to the transaction data, and when the transaction processing type is synchronous transaction, sends information that block generation is successful to the transaction sending terminal after the block generation, so as to conveniently and timely inform the transaction user corresponding to the transaction sending terminal that the current transaction is completed.
in one embodiment, the verifying the target endorsement result by the first endorsement node in the blockchain transaction data processing method may include: the method comprises the steps that a first endorsement node acquires a preset transaction strategy; acquiring each endorsement result in the target endorsement result, and detecting whether each endorsement result in the target endorsement result follows a transaction strategy or not; when each endorsement result in the target endorsement results conforms to the transaction strategy, the target endorsement results are verified.
Specifically, the transaction policy may invoke a chaincode (verification system) associated with the first endorsement node to detect whether the transaction data was successfully endorsed. The verification of the target endorsement result by the first endorsement node may be: and obtaining a related verification system, checking whether each endorsement result in the target endorsement result is legal through the verification system, and when each endorsement result in the target endorsement result checked by the verification system passes verification, namely each endorsement result is legal, verifying the target endorsement through the verification system.
In this embodiment, the first endorsement node determines the endorsement result by verifying each endorsement result in the target endorsement result, and when each endorsement result passes verification, determines that the target endorsement passes verification, so that each endorsement in the target endorsement result is verified, and the verification result is more accurate.
In one embodiment, the blockchain transaction data processing method may further include, after detecting whether each endorsement result in the target endorsement results complies with the transaction policy: when the endorsement result in the target endorsement result does not follow the transaction strategy, generating block generation failure information; and the first endorsement node acquires a transaction sending terminal corresponding to the transaction data and sends the information of transaction failure to the transaction sending terminal.
specifically, when the first endorsement result verifies the target endorsement result, if the endorsement result in the target endorsement result does not pass the verification of the verification system, it indicates that abnormal data which cannot enter a chain exists in the transaction data, and a subsequent transaction block cannot be generated, and if the transaction fails, the first endorsement node acquires the address of the transaction sending terminal, sends a block generation failure, that is, a transaction failure message to the transaction sending terminal, and reminds a user corresponding to the transaction data that the transaction data fails to enter the chain.
in this embodiment, when the first endorsement node sends the information that the block generation is successful to the transaction sending terminal after the block generation, the transaction sending terminal is convenient to inform the transaction user corresponding to the transaction sending terminal that the current transaction has failed in time.
in an embodiment of the method for processing blockchain transaction data, the first endorsement node integrates the target endorsement result obtained by the first endorsement operation and the second endorsement operation, verifies whether the target endorsement result passes verification, generates a transaction block corresponding to the transaction data when the target endorsement result passes verification, and completes the transaction by entering the transaction data into a chain. For example, after a certain company performs a transaction, data related to the transaction is obtained, and an in-chain operation of the transaction related data needs to be completed, the first endorsement node receives the transaction related data, obtains a second endorsement node that needs to endorse the transaction data according to an endorsement policy, sends the transaction related data to the second endorsement node, integrates endorsement results of the first endorsement node and the second endorsement node to obtain a target endorsement result, sends the target endorsement result to the consensus node sorting and dividing block, generates a transaction block corresponding to the transaction related data according to the sorting and dividing result, and generates and indicates that the transaction data is successfully in-chain. The block chain transaction is completed through the information transmission between the first endorsement node and the second endorsement node and the consensus node, and compared with the traditional method for transmitting the information between the transaction server and the nodes, the method reduces network call and saves resources.
