Description

Technical Field

[0001] This invention relates to the field of communications, and more particularly to a blockchain-based transaction control method, apparatus, and storage medium. Background Technology

[0002] Blockchain operates based on smart contracts. Currently, the methods for managing the gray-scale release of smart contracts in the market are relatively simple, and they are all based on versions. For example, there is a running smart contract version A, and a smart contract version B is to be released in the gray-scale release: Contract version B is tested in the test environment. After the test is passed, it is released to production to replace all contract versions A (if not all are replaced, inconsistencies will occur when calling). If an error occurs, the contract version is rolled back to version A. In this solution, all nodes install the same smart contract to process transactions, resulting in low intelligence in transaction processing. Summary of the Invention

[0028] The acquisition module, upon receiving a transaction request, acquires the transaction information and transaction attribute information in the transaction request, acquires the smart contract grayscale strategy corresponding to the transaction attribute information, and acquires the target node according to the grayscale version in the smart contract grayscale strategy.

[0029] The sending module is used to send the transaction information to the target node in the blockchain, so that the node can call the corresponding grayscale version of the smart contract to process the transaction information.

[0040] Figure 8 This is a schematic diagram of the blockchain-based transaction control device of the present invention. Detailed Implementation

[0041] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0042] Reference Figure 1 , Figure 1 This is a schematic diagram of the hardware architecture of the device involved in the blockchain-based transaction control method of the present invention.

[0043] like Figure 1 As shown, the blockchain-based transaction control device involved in this embodiment can be a server. In this embodiment, the server is connected to the blockchain to manage the various nodes in the blockchain.

[0044] The blockchain-based transaction control device in this embodiment may include a memory 110, a processor 120, and a communication module 130. The memory 110 is used to store a blockchain-based transaction control program; the processor 120 is used to execute the blockchain-based transaction control program in the memory 110; and the communication module 130 is used to communicate with various nodes in the blockchain.

[0045] In the technical solution disclosed in this embodiment, when the blockchain-based transaction control program in the memory 110 is executed by the processor 120, it performs the following steps:

[0046] Upon receiving a transaction request, obtain the transaction information and transaction attribute information from the transaction request;

[0047] Obtain the smart contract grayscale strategy corresponding to the transaction attribute information;

[0048] The target node is obtained according to the grayscale version in the smart contract grayscale strategy;

[0049] The transaction information is sent to the target node in the blockchain so that the node can call the corresponding grayscale version of the smart contract to process the transaction information.

[0050] Reference Figure 2 , Figure 2 This is a flowchart illustrating an exemplary embodiment of the blockchain-based transaction control method of the present invention. In this embodiment, the blockchain-based transaction control method includes:

[0051] Step S10: After receiving the transaction request, obtain the transaction information and transaction attribute information in the transaction request;

[0052] The transaction attribute information in this embodiment includes at least one of the grayscale version, user information, terminal information, and business type. The grayscale version may correspond to the version of the smart contract installed in the node. The user information may be the user type information or the user identification information. The terminal information may be the terminal type information, the terminal IP address information, or the terminal identification information. The business type can be obtained through the business identification information or the source of the business.

[0053] Step S20: Obtain the smart contract grayscale strategy corresponding to the transaction attribute information;

[0054] In the technical solution disclosed in this application, grayscale environment version isolation can be achieved through transaction attribute information. The corresponding smart contract grayscale strategy can be obtained based on the transaction attribute information. The smart contract grayscale strategy contains the corresponding grayscale version and the execution ratio of the corresponding version. For example, the execution ratio of version A is 20% and the execution ratio of version B is 80%. Then, the transaction information can be allocated according to the execution ratio.

[0055] Step S30: Obtain the target node according to the gray version in the smart contract gray-scale strategy;

[0056] Since different smart contracts run on different nodes, meaning different target nodes correspond to different grayscale versions, the corresponding target node can be obtained through the grayscale version in the grayscale strategy.

[0057] Step S40: Send the transaction information to the target node in the blockchain so that the node can call the corresponding grayscale version of the smart contract to process the transaction information.

[0058] In this embodiment, when the target node in the blockchain receives transaction information, it can process the transaction information through a smart contract. During the process of the target node processing the transaction information, the processing process of the target node can be monitored by a monitoring device, which can record the gray-scale transaction log, response time, transaction parameters and transaction results of each transaction, so as to manage the transaction process.

[0059] In the technical solution disclosed in this embodiment, after receiving a transaction request, the transaction information and transaction attribute information in the transaction request are obtained, the smart contract grayscale strategy corresponding to the transaction attribute information is obtained, the target node is obtained according to the grayscale version in the smart contract grayscale strategy, and the transaction information is sent to the target node in the blockchain so that the node can call the corresponding grayscale version of the smart contract to process the transaction information. In this solution, different smart contracts are called for processing different transaction information, which improves the intelligence and accuracy of transaction control.

[0060] Reference Figure 3 Based on Embodiment 1, Embodiment 2 of the blockchain-based transaction control method of the present invention is proposed. In this embodiment, step S30 includes:

[0061] Step S31: Combine the smart contract grayscale strategies corresponding to each of the transaction attribute information to obtain a combined grayscale strategy.

[0062] Step S32: Obtain the target node according to the grayscale version in the combined grayscale strategy.

[0063] In the technical solution disclosed in this embodiment, there may often be multiple transaction attribute information, such as... Figure 4 As shown, the grayscale strategies of smart contracts corresponding to multiple transaction attribute information can be superimposed to form a combined grayscale strategy. For example, the grayscale strategies of smart contracts corresponding to user information and terminal information can be combined to form a user terminal combined strategy. When combining strategies, multiple smart contract grayscale strategies can be combined directly, or the grayscale strategies of smart contracts can be averaged, weighted averaged, and / or summed. The corresponding combined strategy can be set as needed.

[0064] In this embodiment, after determining the combined grayscale strategy, the target node is determined according to the grayscale version corresponding to the combined grayscale strategy.

[0065] Reference Figure 5 Based on Embodiment 1, Embodiment 3 of the blockchain-based transaction control method of the present invention is proposed. In this embodiment, step S30 includes:

[0066] Step S33: Obtain the target blockchain corresponding to the transaction attribute information;

[0067] Step S34: Obtain the target node in the target blockchain according to the gray version in the smart contract gray-scale strategy.

[0068] The target blockchain can be obtained through preset fields in the transaction attribute information, such as the `chain_engine` parameter. If the `chain_engine` parameter matches `fabric`, the transaction is distributed to the `fabric` network for gray-scale trading; if it matches `cita`, the transaction is distributed to the `cita` network for gray-scale trading; if it matches `eos`, the transaction is distributed to the `eos` network for gray-scale trading; alternatively, if the `chain_engine` parameter does not match any of the above fields, an error message can be output.

[0069] In the technical solution disclosed in this embodiment, the blockchain is distinguished by transaction information, making transaction control more intelligent and accurate.

[0070] Reference Figure 6 Based on the first to third embodiments, a fourth embodiment of the blockchain-based transaction control method of the present invention is proposed. In this embodiment, before step S10, the blockchain-based transaction control method further includes:

[0071] Step S50: After receiving the smart contract program file uploaded by the client, obtain the gray version corresponding to the smart contract program file, and configure the gray management strategy according to the gray version.

[0072] Step S60: Obtain the installation node corresponding to the smart contract program file;

[0073] Step S70: Send the smart contract program file to the installation node so that the installation node can install the smart contract program file;

[0074] Step S80: Save the installation node, grayscale management strategy, and transaction attribute information together.

[0075] In the technical solution disclosed in this embodiment, after the latest version of the smart contract is released, the client can upload the smart contract program file to the server. The server can provide a visual configuration interface to the client. Users can configure the gray version, gray management strategy and installation node through the visual configuration interface. After the user completes the configuration, the smart contract program file is sent to the installation node selected by the user.

[0076] After installing the new version of the smart contract program file, the installation node will cache the original version of the smart contract program file so that it can roll back the version in case of an exception.

[0077] It is understandable that different transactions may correspond to different blockchains, so after step S80, the method further includes: obtaining the blockchain information corresponding to the transaction attribute information; associating the grayscale management strategy with the blockchain information.

[0078] The technical solution disclosed in this embodiment allows users to configure the corresponding grayscale management strategy and the association between transaction attribute information as needed, so that after receiving transaction information, the corresponding grayscale management strategy can be flexibly invoked to manage the transaction, thereby improving the flexibility of the transaction.

[0079] Reference Figure 7 Based on the first to third embodiments, a fourth embodiment of the blockchain-based transaction control method of the present invention is proposed. In this embodiment, after step S40, the method further includes:

[0080] Step S90: Obtain the processing data of the transaction information from each of the target nodes;

[0081] Step S100: When it is determined from the processing data that the smart contract in the target node does not respond to the transaction information or the response time is longer than a preset time, the version of the smart contract in the target node is rolled back.

[0082] In the technical solution disclosed in this embodiment, the execution process of transaction information of each node can be monitored. The monitoring of the execution process of transaction information can be obtained through the node's log file. If the smart contract does not respond to the transaction information or the response time is longer than the preset time, it indicates that the transaction information is not compatible with the smart contract, and the version of the smart contract needs to be rolled back.

[0083] In the technical solution disclosed in this implementation, when the smart contract in the node encounters an anomaly in processing transaction information, a version rollback is performed to improve the accuracy of the processing.

[0084] Reference Figure 8 The present invention also proposes a blockchain-based transaction control device, which operates on an edge node and includes:

[0085] The acquisition module 10, upon receiving a transaction request, acquires the transaction information and transaction attribute information in the transaction request, acquires the smart contract grayscale strategy corresponding to the transaction attribute information, and acquires the target node according to the grayscale version in the smart contract grayscale strategy.

[0086] The sending module 20 is used to send the transaction information to the target node in the blockchain, so that the node can call the corresponding grayscale version of the smart contract to process the transaction information.

[0087] The present invention also proposes a blockchain-based transaction control device, which includes a memory and a processor. The memory is used to store a blockchain-based transaction control program. When the blockchain-based transaction control program in the memory is executed by the processor, it implements the blockchain-based transaction control method as described in any of the above embodiments.

[0088] The present invention also proposes a computer-readable storage medium, characterized in that the computer-readable storage medium stores a blockchain-based transaction control program, which, when executed by a processor, implements the steps of the blockchain-based transaction control method as described in the above embodiments.
