In order to make the technical solutions and advantages of the present application clearer, the following further describes the present application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the application, and not used to limit the application.

The blockchain data cleaning method provided in this application can be applied to the application environment shown in FIG. 1. The server 102 communicates with the to-be-cleaned node 106 included in the blockchain system 104 through the network. The server 102 stops each node in the blockchain system 104 and the associated service corresponding to each node; when each node and service in the blockchain stops, it obtains the ordering identifier, and obtains the ordering service from the associated service according to the ordering identifier, and deletes it The data queue in the sorting service generates a data cleaning instruction when the data queue is deleted; then logs in to the node 106 to be cleaned according to the data cleaning instruction, deletes the data to be cleaned in the node 106 to be cleaned, and restarts the associated service corresponding to the node to be cleaned 106 When the associated service restarts, a channel replacement instruction is generated; according to the channel replacement instruction, a new replacement channel is created, and the replacement channel is added to the node to be cleaned 106; finally, the first configuration information of the replacement channel is obtained and the resource exchange server is inquired, according to the first configuration Information modify the channel configuration of the node to be cleaned up and start the resource exchange server. The server 102 and the node to be cleaned 106 can be implemented by an independent server or a server cluster composed of multiple servers. The blockchain system 104 can be a distributed storage system containing different nodes, which can connect blocks generated by different nodes. , To form a blockchain, and store the formed blockchain in different nodes.

In one of the embodiments, as shown in FIG. 2, a method for clearing blockchain data is provided. Taking the method applied to the server 102 in FIG. 1 as an example, the method includes the following steps:

Step 202: Stop each node in the blockchain and the associated service corresponding to each node.

Specifically, each node and associated service in the blockchain may include: a consensus node for sorting data and a sorting service associated with the consensus node, an endorsing node for verifying whether the data is legal, and an endorsement associated with the endorsing node Services, data nodes for data storage and data storage services associated with data nodes, transaction nodes for initiating and stopping transactions, transaction initiation services associated with transaction nodes, etc. The server stops the above nodes in the blockchain and Its associated service prepares for the subsequent data cleaning in the blockchain.

Step 204: Obtain the sorting identifier, obtain the sorting service from the associated service according to the sorting identifier, and delete the data queue in the sorting service. When the data queue is deleted, a data cleaning instruction is generated.

Specifically, the ordering identifier is used to identify the ordering service in the consensus node, such as the kafka service connected to the consensus node. The data queue may be a data queue of test data to be cleaned, such as a topic (tag) in the kafka service. The data cleansing instruction may be used to instruct the deletion of the data to be cleaned in the node to be cleaned after the data queue is deleted. The server obtains the sorting identifier used to indicate the sorting service, obtains the sorting service connected to the consensus node according to the sorting identifier, and deletes the data queue in the sorting service, and generates a data cleaning instruction.

Step 206: Log in to the node to be cleaned according to the data cleansing instruction, delete the data to be cleaned in the node to be cleaned, and restart the associated service corresponding to the node to be cleaned, and when the associated service restarts, generate a channel replacement instruction.

Specifically, the nodes to be cleaned can include consensus nodes, endorsement nodes, and data nodes in the blockchain. The data to be cleaned can be residual data for testing, such as channel data in consensus nodes, endorsement nodes, and ledger data in data nodes. , Transient data, etc. After the server obtains the data cleaning instruction, it logs in to the node to be cleaned according to the data cleaning instruction, and deletes the data to be cleaned in the node to be cleaned. After the data to be cleaned in the node to be cleaned is deleted, restart the associated service in the node to be cleaned : It can include consensus nodes and associated ranking services, endorsement nodes and associated endorsement services, data nodes and associated data storage services, and generated channel replacement instructions. The channel replacement instructions are used to instruct replacement channel generation and replacement channel replacement.

Step 208: Create a new replacement channel according to the channel replacement instruction, and add the replacement channel to the node to be cleaned.

Specifically, the replacement channel is used to replace the blockchain channel of the original data channel of the data to be cleaned. After the data to be cleaned is deleted, the original data channel where the data to be cleaned is located is also deleted. The specific method for establishing the blockchain channel includes entering Docker cli container (a software package used for code processing, data operation, and system settings in the blockchain), and then set the environment variables of the channel, and add the channel-related configuration data to the channel and other steps, in the new blockchain for replacement After the channel is completed, the replacement channel is added to the consensus node, endorsement node, and data node to be cleaned up.

Step 210: Obtain the first configuration information of the replacement channel and query the resource exchange server, modify the channel configuration of the node to be cleaned up according to the first configuration information, and start the resource exchange server.

Specifically, the first configuration information may be standard information of the replacement channel, such as information such as the maximum number of transactions and the maximum number of bytes. After obtaining the first configuration information of the new replacement channel, the server modifies the node to be cleaned according to the first configuration information. The original channel configuration, and query the status of the resource exchange server, if the resource exchange server is not turned on, start the resource exchange server, if the resource exchange server is in the on state, restart the resource exchange server.

In the above block chain data cleaning method, the server stops each node in the block chain and the associated service corresponding to each node; when each node and service in the block chain stops, it obtains the sorting identifier, and according to the sorting identifier from the associated service Obtain the sorting service and delete the data queue in the sorting service. When the data queue is deleted, generate a data cleaning instruction; then log in to the node to be cleaned according to the data cleansing instruction, delete the data to be cleaned in the node to be cleaned, and restart the corresponding node to be cleaned When the associated service restarts, a channel replacement instruction is generated; according to the channel replacement instruction, a new replacement channel is created, and the replacement channel is added to the node to be cleaned; finally, the first configuration information of the replacement channel is obtained and the resource exchange server is queried. One configuration information modifies the channel configuration of the node to be cleaned up and starts the resource exchange server. By deleting the data queue in the sorting service, then deleting the data to be cleaned in the cleaning node, and finally replacing the channel, the channel data is cleaned. Compared with the prior art, it provides a method that can clean the data in the blockchain. Blockchain data cleaning method to improve the efficiency of blockchain operation.

In one of the embodiments, as shown in FIG. 3, in the blockchain data cleaning method, before deleting the data to be cleaned in the node to be cleaned, it may further include:

Step 302: When there is calibration data in the data to be cleaned in the node to be cleaned, the calibration data in the node to be cleaned is backed up.

Specifically, the calibration data is the restored data in the data to be cleaned. The restored data can restore the data to be cleaned, and can restore the data to be cleaned when the subsequent error correction or verification is required. The data to be cleaned is detected and corrected, and the server is deleting the data to be cleaned. Before cleaning the data to be cleaned in the node, check whether the data to be cleaned contains calibration data. When the server detects that there is calibration data in the data to be cleaned in the node to be cleaned, it saves the detected calibration data as backup data. Follow-up data verification.

Step 304: When the data verification request is received, restore the data to be cleaned in the node to be cleaned according to the backup calibration data.

Specifically, when the server receives the data verification request, it restores the data to be cleaned in the node to be cleaned according to the calibration data in the backed up data to be cleaned, so that the user can check the data to be cleaned before deletion and check whether the data to be cleaned is There is an exception.

In the above blockchain data cleaning method, the blockchain data cleaning method detects whether the data to be cleaned contains calibration data before cleaning the data. When the data to be cleaned contains calibration data, the calibration data is saved, and the data is subsequently received Restore when verifying the request to facilitate users to find errors in blockchain data.

In one of the embodiments, after the blockchain data cleaning method obtains the first configuration information of the replacement channel and queries the resource exchange server, it may also include: obtaining the second configuration information of the historical channel in the history record, and combining the second configuration information with The first configuration information is matched; when the matching is successful, the resource exchange server is started.

Specifically, the second configuration information refers to the configuration information of the historical data channel in the historical record. After the server obtains the first configuration information of the replacement channel and queries the current state of the resource exchange server, query the historical data in the historical record in the blockchain The second configuration information of the channel, and the first configuration information of the replacement channel is matched with the second configuration information in the history record. When the second configuration information in the history record matches the first configuration information of the replacement channel, the two If the second configuration information of the historical record meets the configuration requirements of the replacement channel, the step of modifying the channel configuration of the node to be cleaned according to the first configuration information is skipped, and the server is directly started.

In this embodiment, the server checks whether there is configuration information matching the first configuration information of the replacement channel by acquiring the second configuration information of the historical channel in the history record. When it exists, it can skip the channel configuration modification step directly, saving the server Resources.

In one of the embodiments, the blockchain data cleaning method stopping each node in the blockchain and the associated service corresponding to each node may include: receiving a data cleaning instruction sent by a terminal, and the data cleaning instruction includes a terminal identifier; obtaining The set of clearing authority terminals is to detect whether the terminal identifier matches the terminal identifier in the clearing authority terminal set; when the terminal identifier matches the terminal identifier in the clearing authority terminal set, stop each node in the blockchain and the associated service corresponding to each node. .

Specifically, the set of clearing authority terminals is a set of fixed terminals, IP frequency bands and other authority lists, and the terminal identifier is the identification information of the data clearing sender terminal, which is included in the data clearing instruction and is used to point to the data clearing sender's terminal. When the server receives the data cleaning instruction sent by the terminal, it obtains the terminal identification contained in the data cleaning instruction, and uses the terminal identification to detect whether the terminal issuing the data cleaning instruction is in the set of cleaning authority terminals, and if the terminal issuing the data cleaning instruction is in the cleaning authority In the terminal set, the subsequent block chain data cleaning work is started, that is, each node in the block chain and the associated service corresponding to each node are stopped. In addition, if the terminal that issued the data cleaning instruction is not in the set of clearing authority terminals, the identity of the terminal that issued the cleaning instruction can be verified.

In this embodiment, the server detects whether the terminal sending the data cleaning instruction matches the set of cleaning authority terminals, and when it matches, it starts the data cleaning of the blockchain, which prevents other users without the authority from cleaning the blockchain data and guarantees The security of blockchain data.

In one of the embodiments, the block chain data cleaning method stops each node in the block chain and the associated service corresponding to each node, which may include: obtaining the data volume of the data to be cleaned, and determining whether the data volume of the data to be cleaned is greater than Preset value; when the amount of data to be cleaned is greater than the preset value, stop each node in the blockchain and the associated service corresponding to each node.

Specifically, the preset value may be a critical value. When the amount of data to be cleaned is greater than the critical value, the operating efficiency of the blockchain will be significantly reduced. The server detects the amount of data to be cleaned and determines whether the detected data amount is greater than The preset value. When the data volume of the data to be cleaned is greater than the preset value, the subsequent blockchain data cleanup work is started, that is, each node in the blockchain and the associated service corresponding to each node are stopped. In addition, a preset period can be set, and the server will periodically detect the amount of data to be cleaned according to the preset period, so as to regularly ensure the operating efficiency of the blockchain.

In this embodiment, the server detects whether the data volume of the data to be cleaned is greater than a preset value, and when the data volume is greater than the preset value, it starts the data cleansing work of the blockchain, which can affect the operation efficiency when the data to be cleaned Data cleaning ensures the operational efficiency of the blockchain.

In one of the embodiments, in the above blockchain data cleaning method, the server deletes the data queue in the sorting service by stopping each node and associated service in the blockchain, deletes the data to be cleaned in the node to be cleaned, and restarts the new replacement channel Steps such as the resource exchange server clean up the data to be cleaned in the blockchain. For example, during the operation of the blockchain, a lot of test data is left due to data testing and other reasons. The test data loses its effect after the test, and the test data will also affect the efficiency of the blockchain when processing other data, and the server stops. Each node in the blockchain and the associated service corresponding to each node, then obtain the kafka service in the consensus node, delete the data queue (topic) in the kafka service, and secondly, delete the test data on the consensus node, endorse the node and the data node Test data (ledger data and transient data) on the computer, then create a replacement channel, add the replacement channel to the node where the data is deleted, and start the resource exchange server. This cleans up the data in the blockchain, thereby improving the efficiency of the blockchain data cleaning method.
