[0038] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and are not to be construed as limitations of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0039] Figure 1 It is a flowchart of a blockchain transaction processing method proposed in an embodiment of the present disclosure.

[0040] Among them, it should be noted that the executor of the blockchain transaction processing method of this embodiment is a blockchain transaction processing device, which can be implemented by software and / or hardware. The device can be configured in an electronic device, and the electronic device can include but is not limited to a terminal, a server, etc. For example, the terminal can be a mobile phone, a handheld computer, etc.

[0041] like Figure 1 As shown, the blockchain transaction processing method is executed by the blockchain hardware board, and the method includes:

[0042] The blockchain transaction processing method in the disclosed embodiment is executed by a blockchain hardware board. The blockchain hardware board is installed on a server running a blockchain node through a PCIE interface. The hardware board and the CPU and memory of the server host transmit data through the Peripheral Component Interconnect Express (PCIE) protocol. It uses a hardware board mode to replace the virtual machine in the Fabric smart contract. It can be directly used to execute smart contracts and can also support the expansion of the blockchain network to accommodate more users and smart contract applications.

[0043] S101: Sending a preprocessing result to a host computer, wherein the preprocessing result is obtained by preprocessing initial transaction data packets of multiple pending transactions according to the smart contract, and the preprocessing result is used to indicate: pending transactions that lack status data of smart contracts during execution.

[0044] Among them, the preprocessing result is obtained by preprocessing the initial transaction data packets of multiple transactions to be executed according to the smart contract. The preprocessing result is used to indicate: the transactions to be executed lack the status data of the smart contract during the execution process.

[0045] Among them, a smart contract is a computer program that automatically executes, manages and enforces the terms of a contract. Specifically, a smart contract is a computer program or transaction protocol based on blockchain technology that allows trusted transactions without a third party.

[0046] In the blockchain, a transaction is a digital record that records the exchange of data or assets between participants in the network. It can be the transfer of ownership of cryptocurrency or the exchange of other types of data or assets.

[0047] Among them, the transactions currently to be executed in the blockchain are pending transactions.

[0048] The data packet consisting of data related to the transaction to be executed is the initial transaction data packet, which may include: transaction input parameters, calling methods and other data.

[0049] The state data of a smart contract refers to the current storage of the contract on the blockchain. These data represent the current state of the contract, including all variable values, balances, and other related information. These state data continue to change with the addition of each block.

[0050] For example, a transaction to be executed may be: "User A transfers x million yuan to user B". The initial transaction data may be, for example, transferor: user A, recipient: user B, transfer amount: x million yuan. The status data may be, for example, account balance of user A, account balance of user B, etc., without any restriction.

[0051] Optionally, in some embodiments, before sending the preprocessing result to the host computer, the blockchain hardware board may be a receiving device for an initial transaction data packet of a transaction to be executed sent by the host computer, wherein the transaction to be executed has a corresponding smart contract, and preprocessing multiple initial transaction data packets according to the smart contract to obtain the preprocessing result.

[0052] That is to say, in the embodiment of the present disclosure, the initial transaction data packet and the smart contract can be moved to the operating space of the blockchain hardware board for operation, so as to perform pre-execution processing on multiple transactions to be executed and obtain pre-processing results.

[0053] Optionally, in some embodiments, multiple initial transaction data are preprocessed according to the smart contract to obtain a preprocessing result. Multiple initial transaction data packets are preprocessed according to the smart contract, and during the preprocessing process, it is determined whether the corresponding transaction to be executed lacks status data. When it is determined that the transaction to be executed lacks status data, the target transaction identifier of the transaction to be executed is determined, and then the preprocessing result is generated based on at least one target transaction identifier.

[0054] Among them, the target transaction identifier is the identification information of the transaction to be executed that lacks the status data of the smart contract. The identification information can be, for example: transaction ID, transaction amount, etc., without limitation.

[0055] That is to say, in the embodiments of the present disclosure, the blockchain hardware board may perform pre-execution processing on multiple pending transactions. If, during the pre-execution process, it is found that the calculation parameters of the transaction lack the state necessary for the transaction execution, the target transaction identifier corresponding to the pending transaction may be determined. When the multiple pending transactions are pre-executed by the blockchain hardware board, all transactions lacking state data in the multiple pending transactions are marked (i.e., all target transaction identifiers of the pending transactions lacking state data may be determined). Then, the multiple target transaction identifiers may be packaged as pre-processing results according to the specified data structure and communication protocol, and the pre-processing results may be sent to the host computer so that the host computer can feedback the corresponding state data according to the pre-processing results. For details, please refer to the subsequent embodiments and will not be repeated here.

[0056] S102: Receive target state data corresponding to the preprocessing result sent by the host computer.

[0057] In the embodiment of the present disclosure, after the preprocessing result is sent to the host computer, status data corresponding to the preprocessing result sent by the host computer may be received.

[0058] S103: writing the target state data into the initial transaction data packet of the corresponding transaction to be executed to obtain the target transaction data packet.

[0059] Among them, after the target state data corresponding to the transaction to be executed is written into the corresponding initial transaction data packet, the target transaction data packet can be obtained.

[0060] In the disclosed embodiment, after receiving the target state data corresponding to the preprocessing result sent by the host computer, the target state data may be written into an initial transaction data packet of the corresponding transaction to be executed to obtain a target transaction data packet.

[0061] That is to say, in the embodiment of the present disclosure, after determining the target state data, the target state data may be written into the initial transaction data packet of the corresponding transaction to be executed in the blockchain hardware board to obtain the target transaction data packet.

[0062] S104: Batch process the target transaction data packet and / or the initial transaction data packet according to the smart contract to batch execute multiple pending transactions to obtain transaction execution results.

[0063] The transaction execution result refers to the final status of a transaction after it is processed and confirmed on the blockchain network. This status usually reflects whether the transaction is successfully completed and the impact of the transaction on the blockchain status, which is not restricted.

[0064] In the disclosed embodiment, after the target status data is written into the initial transaction data packet of the corresponding transaction to be executed to obtain the target transaction data packet, it can be ensured that the status data required for all transactions to be executed already exist. Thus, the target transaction data packet and / or the initial transaction data packet can be batch processed according to the smart contract to batch execute multiple transactions to be executed at one time and obtain the batch execution results of all transactions to be executed.

[0065] In the embodiment of the present disclosure, if the preprocessing result indicates that all pending transactions are not lacking in corresponding status data, that is, the initial transaction data packet can already support the execution of pending transactions, then the initial transaction data packet can be batch processed according to the smart contract to execute the pending transactions in batches. If the preprocessing result indicates that all pending transactions are lacking in corresponding status data, then the target transaction data packet can be batch processed according to the smart contract to execute the pending transactions in batches. If the preprocessing result indicates that some pending transactions are not lacking in corresponding status data, then the initial transaction data packet and the target transaction data packet can be batch processed according to the smart contract to execute the pending transactions in batches. There is no restriction on this.

[0066] In the disclosed embodiment, when accessing the status data, multiple pending transactions can be written into the blockchain hardware board at one time. During the calculation process, all the blockchain states to be accessed are marked at one time and returned to the host computer. After the host computer makes a unified query, it will return all the status data to the blockchain hardware board at one time, and the blockchain hardware board will batch execute all pending transactions accordingly. This simple and efficient access technology can greatly improve the performance of the blockchain hardware board in processing smart contract transactions. In addition, the blockchain hardware board has a proprietary memory protection mechanism that can prevent transaction data and status data from being stolen during the interaction between the two, which greatly improves the security of the status data.

[0067] Optionally, in some embodiments, after the target transaction data packet and / or the initial transaction data packet are batch processed according to the smart contract to batch execute multiple transactions to be executed to obtain transaction execution results, the transaction execution results can be sent to the host computer, thereby prompting the host computer to feed back the batch execution results of multiple transactions to be executed to the blockchain block.

[0068] In the disclosed embodiment, when the host computer queries the target status data according to the preprocessing result, the pre-execution process of the transaction to be executed will be released from the blockchain hardware board, thereby avoiding occupying the memory resources of the blockchain hardware board, optimizing process scheduling, reducing the system burden, and enhancing system stability.

[0069] In the disclosed embodiment, the blockchain hardware board sends a preprocessing result to the host computer, wherein the preprocessing result is obtained by preprocessing the initial transaction data packets of multiple transactions to be executed according to the smart contract, and the preprocessing result is used to indicate: a transaction to be executed that lacks the status data of the smart contract during the execution process, and then receives the target status data corresponding to the preprocessing result sent by the host computer, and then writes the target status data into the initial transaction data packet of the corresponding transaction to be executed to obtain the target transaction data packet, and then batch processes the target transaction data packet and / or the initial transaction data packet according to the smart contract to batch execute multiple transactions to be executed to obtain the transaction execution result, thereby, through the pre-execution process, all the missing status data can be determined at one time, and then, all the missing status data can be read at one time according to the preprocessing result of the pre-execution process, and the status data can be written to the blockchain hardware board at one time, thereby reducing the number of interactions between the hardware and the blockchain status database, and improving the efficiency and security of smart contract execution.

[0070] Figure 2 It is a flowchart of a blockchain transaction processing method proposed in an embodiment of the present disclosure.

[0071] Among them, it should be noted that the executor of the blockchain transaction processing method of this embodiment is a blockchain transaction processing device, which can be implemented by software and / or hardware. The device can be configured in an electronic device, and the electronic device can include but is not limited to a terminal, a server, etc. For example, the terminal can be a mobile phone, a handheld computer, etc.

[0072] like Figure 2 As shown, the blockchain transaction processing method includes:

[0073] S201: Receive a preprocessing result sent by a blockchain hardware board, wherein the preprocessing result is obtained by the blockchain hardware board preprocessing initial transaction data packets of multiple transactions to be executed according to the smart contract, and the preprocessing result is used to indicate: a transaction to be executed that lacks status data of the smart contract during execution.

[0074] The blockchain transaction processing method described in the embodiments of the present disclosure may be executed by a host computer, which may include: a blockchain base chain and a smart contract parallel programming tool, and data transmission between the host computer and the blockchain hardware board is based on the PCIE protocol.

[0075] Optionally, in some embodiments, the host computer can also determine multiple transactions to be executed from the transaction pool of the blockchain, determine the initial transaction data packet corresponding to each transaction to be executed, and then send the initial transaction data packet corresponding to each transaction to be executed to the blockchain hardware board.

[0076] That is to say, in the embodiment of the present disclosure, the smart contract parallel programming tool in the host computer collects pending transactions from the transaction pool in an asynchronous manner, and determines the core information such as input parameters and calling methods corresponding to each pending transaction, and packages the aforementioned information into an initial transaction data packet according to the specified data structure and communication protocol, and sends the initial transaction data packet corresponding to each pending transaction to the blockchain hardware board based on the PCIE protocol, so that the blockchain hardware board can pre-process multiple initial transaction data packets according to the smart contract to obtain corresponding pre-processing results.

[0077] In the disclosed embodiment, the smart contract parallel programming tool in the host computer can receive the preprocessing results sent by the blockchain hardware board, and then trigger the execution of subsequent blockchain transaction processing methods according to the preprocessing results. For details, please refer to the subsequent embodiments and will not be repeated here.

[0078] S202: Parse the preprocessing result to obtain a target transaction identifier, wherein the target transaction identifier is an identifier of a transaction to be executed that lacks status data of a smart contract.

[0079] In the disclosed embodiment, after receiving the preprocessing result sent by the blockchain hardware board, the preprocessing result is parsed to obtain the target transaction identifier.

[0080] In the disclosed embodiment, since the preprocessing result is obtained by the blockchain hardware board packaging at least one target transaction identifier according to the specified data structure and communication protocol, the smart contract parallel programming tool in the host computer can receive the preprocessing result sent by the blockchain hardware board, and then parse the processing result according to the specified data structure and communication protocol to obtain the target transaction identifier.

[0081] S203: Query the target state data corresponding to the target transaction identifier from the blockchain.

[0082] In the disclosed embodiment, after the smart contract parallel programming tool in the host computer parses the preprocessing result to obtain the target transaction identifier, it can read the target state data corresponding to the target transaction identifier in the state database of the blockchain according to the target transaction identifier.

[0083] S204: Send target status data to the blockchain hardware board.

[0084] In the disclosed embodiment, after querying the target status data corresponding to the target transaction identifier from the blockchain, the smart contract parallel programming tool in the host computer can send the target status data to the blockchain hardware board based on the PCIE protocol to provide the necessary conditions for the blockchain hardware board to execute the pending transaction.

[0085] In the embodiments of the present disclosure, see Figure 3 , Figure 3 It is a schematic diagram of the blockchain transaction processing flow proposed by another embodiment of the present disclosure. The smart contract parallel programming tool in the upper computer can obtain multiple pending transactions from the transaction pool of the blockchain bottom chain, and write the initial transaction data packets of the pending transactions into the blockchain hardware board in batches. The blockchain hardware board will pre-process the initial transaction data packet according to the smart contract to obtain the pre-processing result, and feed the pre-processing result back to the smart contract parallel programming tool. Then, the smart contract parallel programming tool will parse the pre-processing result to obtain the target transaction identifier, and then obtain the target state data according to the target transaction identifier, and write the target state data into the blockchain hardware board in batches. The blockchain hardware board will batch process the target transaction data packet and / or the initial transaction data packet according to the smart contract to batch execute multiple pending transactions to obtain transaction execution results, and then send the transaction execution results to the smart contract parallel programming tool. The smart contract parallel programming tool will return the transaction execution results in batches to the candidate transaction blocks in the blockchain bottom chain. The blockchain bottom chain will execute consensus, generate new data blocks according to the transaction execution results, and then update the ledger according to the new data blocks to obtain a new ledger read-write set.

[0086] In the disclosed embodiment, the host computer receives the preprocessing result sent by the blockchain hardware board, wherein the preprocessing result is obtained by the blockchain hardware board preprocessing the initial transaction data packets of multiple transactions to be executed according to the smart contract, and the preprocessing result is used to indicate: the transaction to be executed that lacks the status data of the smart contract during the execution process, and then the preprocessing result is parsed to obtain the target transaction identifier, wherein the target transaction identifier is the identifier of the transaction to be executed that lacks the status data of the smart contract, and then the target status data corresponding to the target transaction identifier is queried from the blockchain, and then the target status data is sent to the blockchain hardware board. As a result, the host computer can query multiple target status data required for all transactions to be executed at one time according to the preprocessing result fed back by the blockchain hardware board, thereby reducing the number of visits to the blockchain status database, and the query efficiency of the target status data is relatively high.
