Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. 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.
In order to solve the risk that the common gray scale release method introduces error data into a production environment, the embodiment of the invention provides a block chain system gray scale release method. As shown in fig. 1, a separately isolated block chain system gray environment is built, and the actual production transaction is guided to the gray environment through a block data synchronization device for replay verification. And on the premise of fully verifying the data correctness, selecting the production nodes in the maximum fault-tolerant range of the block chain cluster for upgrading, and verifying the consensus strategy of the block chain. The error data generated during the gray scale distribution can be recovered by the fault-tolerant capability of the blockchain system. By the method, the gray level release of the version is completed on the premise of avoiding the pollution of error data to production environment.
Fig. 2 is a flowchart illustrating a gray scale publishing method of a blockchain system according to an embodiment of the invention. As shown in fig. 2, the method for releasing the gray scale in the blockchain system may include the following steps:
s100: and building a block chain system gray level environment.
Specifically, a block chain system gray level environment is built by referring to a block chain system production environment. The gray level environment can be built according to specific requirements in a mode of reducing the production environment by 1:1 in an equal proportion, and can also be built in a mode of deploying multiple instances on a single node. The consensus algorithm between blockchain instances in a blockchain system gray scale environment may be kept consistent with the production environment, or other different consensus algorithms, such as SOLO, may be selected.
S200: and building and configuring a block data synchronization device.
Specifically, the block data synchronization device is mainly used for analyzing and restoring transaction block data really generated in a production environment into block chain transactions, and forwarding the block chain transactions to a block chain gray scale environment for transaction playback, so that information such as production environment nodes needing synchronization and block heights starting synchronization needs to be configured in advance, and data synchronization is started.
S300: the gray scale environment synchronously produces the environmental block data.
Specifically, in order to ensure the authenticity of the gray scale environment data verification, before the gray scale release verification is started, the consistency between the gray scale environment data and the production environment data needs to be ensured, so that the complete block data needs to be synchronized to the gray scale environment from the starting block. Of course, the block data synchronization may also be performed from the block height allocated in step S200 in combination with the actual verification requirement, so as to speed up the synchronization efficiency of the block data.
S400: and upgrading the node version of the gray environment.
Specifically, the main purpose of the gray release is to verify the correctness of the new version program of the blockchain system, so that the program version of the gray environment is preferentially upgraded, such as the version of the gray node 1 shown in fig. 1 is upgraded to the version V2, and a real production transaction is performed through the new version program to verify the correctness of the version.
S500: the correctness is verified using the blockchain data verification device.
If the verification is passed, executing step S700; if the verification is not passed, executing step S600;
specifically, the block chain data verification device is mainly used for verifying the correctness of the block data packaged by the new version program and the block data written into the block chain.
S600: and (5) backing off the gray environment node.
At this time, the error has no influence on the production environment, the block data synchronization device is disconnected and closed, and the gray level node is cleared.
S700: and selecting a single node upgrading version of the production environment.
Specifically, the verification of the correctness of the block data packaging and the block data writing is already completed in step S500, but the correctness of the transaction processing under the coexistence of the blockchain consensus mechanism and the old and new versions needs to be further verified, so that the verification of the upgrade version of a single node needs to be selected in the production environment.
Specifically, for the case that a single node has multiple instances, a single instance is selected for upgrade version verification.
S800: the correctness is verified using the blockchain data verification device.
If the verification is passed, executing step S1000; if the verification is not passed, executing step S900;
specifically, the block chain data verification device in this step is mainly used for verifying the correctness of the block chain consensus mechanism.
S900: the upgraded node (instance) is disconnected from the blockchain cluster.
Specifically, since the new version verification fails, the node (instance) needs to be disconnected from the production blockchain cluster in order to prevent the impact of errors on the production system.
S910: the upgraded node (instance) version rolls back and clears the block data.
Since the upgraded node (instance) has already stored the error data, the upgraded version needs to be rolled back and the block data emptied.
S920: the upgraded node (instance) rejoins the production environment blockchain cluster and resynchronizes the blockchain data.
The upgraded node (instance) can be added into the production blockchain cluster again after returning, and the synchronization and recovery of the production data are completed by the synchronization mechanism of the blockchain system.
S1000: and judging whether the number of the current upgraded nodes (the number of the examples) is less than or equal to the maximum fault-tolerant number of the cluster. If yes, go to step S700; if not: step S1100 is performed.
Specifically, because the blockchain system has a fault-tolerant mechanism, in order to more fully verify a new version program and reduce the production risk to the maximum extent, the single node (instance) is upgraded and verified one by one within the fault-tolerant capability range of the blockchain system. The present embodiment takes upgrade one by one as an example, but is not limited to this, and upgrade may also be performed partially at the same time.
S1100: complete the full node (instance) version upgrade.
Fig. 3 is a block data synchronization apparatus according to an embodiment of the invention. As shown in fig. 3, the apparatus mainly comprises a block data reading module 10, a block receiving queue 20, a block processing module 30, and a transaction sending queue 40.
The block data reading module 10 selects a part of block chain nodes (instances) from the block chain system production environment according to preset synchronization parameters to read block data with a specified height, encrypts the original block data, and stores the encrypted block data in the block receiving queue 20 for caching.
The block processing module 30 reads the encrypted block data from the block receiving queue 20, decrypts the block data, and splits the decrypted block data to restore the original transaction information. In order to ensure that the order of the gray level environment transaction playback is consistent with the production environment, the block processing module 30 will perform sequencing check on the analyzed transaction information before writing the transaction data into the transaction transmission queue 40, if there is a situation that the preamble transaction has not been transmitted, the transaction will be buffered, and the transaction will be written into the transaction transmission queue 40 after the preamble transaction reaches the gray level environment, otherwise, the transaction will be directly written into the transaction transmission queue 40 for transaction transmission.
Fig. 4 is a block chain data verification apparatus according to an embodiment of the present invention. As shown in fig. 4, the blockchain data verification device is composed of a transaction receiving module 410, a blockchain query module 420, and a data verification module 430.
The transaction receiving module 410 mainly verifies the relevant parameters of the transaction verification request, wherein the range of the transaction verification request can be specified by parameters such as a main key of a business transaction, transaction time, public key address of a transactor and the like. After the parameter verification is passed, the block query module 420 queries specific block raw data from the production environment and the gray scale environment and forwards the block raw data to the data verification module 430 for verification. The data checking module 430 verifies the correctness of block packaging, block data writing and block consensus by mainly comparing the Hash value of the block data with the transaction element information parsed from the block.
