Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The method and the device improve the defect that in the prior art, when the designated service data needs to be inquired from the block chain in the process of storing the service data based on the block chain, the data in the whole block chain needs to be subjected to traversal inquiry due to the inherent characteristics of the block chain, and the desired data can be acquired. Therefore, when the appointed service data are required to be acquired from the block chain, the inquiry can be directly carried out from the data platform, and the service data in the data platform are stored in a preset storage mode which is convenient to retrieve, so that the inquiry time can be greatly reduced.
Fig. 1 is a schematic diagram of processing logic of blockchain data according to an embodiment of the present invention. As shown in fig. 1, the processing logic mainly includes two parts, the first part is a block chain generation process (block chain generation), and the second part is a service data extraction process that extracts service data that has been stored in a block chain and stores the extracted service data in a data platform in a preset storage manner (block chain storage).
The generation process of the block chain is similar to the data storage process based on the block chain in the prior art, namely, a plurality of processing nodes in the block chain network store the service data to be stored into the block chain through a consensus mechanism; or for the private block chain, the service data to be stored can be directly stored into the block chain by a separate processing node, so as to form block chain data. Here, the processing node in the present embodiment is not limited to the node that generates the blockchain data, and includes a node that manages the blockchain. In the process of forming the block chain, in order to facilitate the later query of the data in the block chain, another block chain storage process can be executed on the formed block chain, that is, the service data in the block chain is copied, extracted and stored in the data platform. The service data in the data platform is stored in a preset storage mode. For example, different classes of service data are classified and stored, and an index setting mechanism is matched. When the business data in the block chain needs to be inquired, the corresponding business data can be directly acquired from the data platform, and the data platform adopts a preset storage mode, so that the appointed business data can be inquired more conveniently and rapidly.
Based on the schematic processing logic diagram of the blockchain data shown in fig. 1, fig. 2 is a structural diagram of a processing system of the blockchain data according to an embodiment of the invention. As shown in fig. 2, the system includes: a processing node 210 arranged in the blockchain network for managing and/or generating blockchains, a processing device 220 for blockchain data interactively connected with the processing node 210, and a data platform 230 for storing business data; wherein:
processing node 210 for managing and/or generating block chains. For example, the processing node 210 may be a node capable of generating service data in a blockchain, or may be a node that has no authority to generate blockchain data, but may participate in or manage the generation process of blockchain data. The processing nodes in the scheme can acquire the service data from the block chain.
The processing device 220 for blockchain data may be in communication connection with the processing node 210, and acquire the certified service data in the blockchain from the processing node 210, or the processing device 220 for blockchain data itself is a processing node in the blockchain network for managing and/or generating the blockchain, and may directly acquire the certified service data in the blockchain (this way may also be understood as that the processing device 220 for blockchain data acquires the service data already stored in the blockchain through the processing node 210, only that the processing node 210 at this time just considers the processing device 220 itself for blockchain data). For example, the processing device 220 of the block chain data may include:
the data acquisition module is used for acquiring the service data stored in the block chain through the processing node;
and the data storage module 220 is configured to store the service data in a preset storage manner in the data platform for querying.
Specifically, while the processing node 220 generates the block chain, the data acquisition module may acquire, through the processing node 220, the service data that has been stored in the block chain. For example, the data acquisition module may actively acquire from a blockchain locally stored by the processing device 220 as blockchain data of a processing node; or after receiving the notification message of the blockchain height sent by another processing node 22, comparing the blockchain height corresponding to the previously acquired blockchain data with the blockchain height in the current notification message, and acquiring the corresponding service data from the blockchain when it is determined that new service data is stored in the blockchain. After the service data is acquired, the data storage module stores the service data in the data platform 230 in a preset storage manner. When the service data in the block chain needs to be queried, the corresponding service data can be directly obtained from the data platform 230, and the data platform 230 can adopt a preset storage mode in any form (convenient for retrieval), so that the specified service data can be queried more conveniently and quickly.
Further, the data acquiring module may specifically include:
a notification receiving unit, configured to receive a notification message carrying a blockchain height sent by a processing node that manages and/or generates a blockchain;
and the data acquisition unit is used for acquiring the service data from the block chain based on the height of the block chain in the notification message.
Specifically, the description is made in the case where the processing node 210 that generates and manages the blockchain and the processing device 220 that processes blockchain data are two independent execution bodies that are separately provided. The notification receiving unit in the data obtaining module may receive a notification message carrying the blockchain height sent by the processing node. The blockchain height is the blockchain height at the time of notification issuance. The data obtaining unit in the data obtaining module may determine whether to obtain the service data from the block chain by referring to the block chain height in the notification message and the block chain height corresponding to the service data that has been obtained before, and perform a corresponding operation.
Further, the above-mentioned data acquisition unit may be specifically adapted,
if the height of the block chain in the notification message received this time is greater than the height of the block chain in the notification message received last time, acquiring service data corresponding to the height of the block chain in the notification message received this time from the block chain;
and/or the presence of a gas in the gas,
and if the height of the block chain in the notification message received this time is equal to the height of the block chain in the notification message received last time, ignoring the notification message received this time.
Specifically, the timing for the processing node to send the notification message containing the height of the block chain may be performed each time the block chain generates new block data (may be repeatedly sent for multiple times to avoid message loss), or may be periodically sent in time sequence. Correspondingly, when determining whether to acquire service data in the block chain, the data acquisition unit may compare the currently received notification message containing the block chain height with the block chain height in the last received notification message containing the block chain height, if the former is greater than the latter, it is described that new service data is stored in the block chain, and the service data with the corresponding height may be acquired from the block chain according to the currently received block chain height; if the former is equal to the latter, it is stated that no new service data in the block chain is stored in the block chain, and at this time the notification message can be ignored, no processing is done, or a direct idempotent return is made.
It should be noted that, when acquiring service data with a corresponding height from a block chain according to the currently received height of the block chain, only the service data newly added with respect to the last received height of the block chain needs to be acquired.
Further, the data obtaining module is configured to obtain all data stored in the blockchain, or obtain service data stored in the blockchain and related to the data type stored in the data platform 230.
Specifically, when acquiring service data from the block chain, all newly added service data may be acquired, so as to ensure that the data platform 230 has the full amount of data of the block chain; the service data stored in the blockchain and related to the data category stored in the data platform 230 may also be acquired, and particularly for the data platform 230 used for storing a certain special category of service data, when acquiring the blockchain data, only the service data related to the data category stored in the service platform may be acquired, thereby reducing the amount of acquired data and reducing the operation cost.
Further, the data storage module is configured to store the service data into the data platform 230 in a manner of matching with the classification index.
Specifically, when data storage is performed, layer-by-layer classification numbers can be set for different types of service data, and then classification indexes are matched for the layer-by-layer classification numbers to store the service data into an appointed storage space, so that retrieval is facilitated.
Further, the data platform 230 further stores location information of the service data in the block chain;
the above apparatus may further include:
a location obtaining module, configured to obtain location information of the service data in the blockchain from the data platform 230;
and the data verification module is used for verifying the correctness of the service data by adopting the consistency characteristic of the block chain based on the position information of the service data in the block chain.
Specifically, while storing the service data to the data platform 230, the location information of each service data in the block chain may also be stored in the data platform 230 in a correlated manner. Therefore, when the authenticity of a certain service data needs to be verified, the position of the service data in the block chain can be traced according to the position information, and then the authenticity of the service data is verified by utilizing the characteristic of unique consistency verification of the block chain, so that the service data is prevented from being maliciously tampered after being stored in the data platform 230.
The technical solution of the present application is further illustrated by the following examples.
Example one
Based on the above concept of the processing scheme of the blockchain data, as shown in fig. 3, it is a flowchart of a processing method of blockchain data according to an embodiment of the present invention, and an execution main body of the method is a processing apparatus of blockchain data shown in fig. 3. As shown in fig. 3, the method for processing blockchain data includes the following steps:
s310, acquiring the service data stored in the block chain.
For example, while a processing node in the blockchain network generates a blockchain, the service data stored in the blockchain may be acquired by the processing node. Typically, such processing nodes will all have the same blockchain stored locally. For example, the acquirer for acquiring the service data is also a processing node for generating and/or managing the blockchain, and the processing nodes may directly acquire the service data in the blockchain locally from the processing node; or after receiving a notification message of the blockchain height sent by another processing node, the acquirer for acquiring the service data compares the blockchain height corresponding to the previously acquired blockchain data with the blockchain height in the notification message, and acquires the corresponding service data from the blockchain when determining that new service data is stored in the blockchain. And after the service data is obtained, obtaining corresponding newly added service data in the block chain.
It should be noted that, in this embodiment, a data acquirer for acquiring the service data from the blockchain and a specific manner of acquiring the data are not limited, as long as the service data in the blockchain can be acquired directly or indirectly.
And S320, storing the service data into a data platform in a preset storage mode for inquiry.
After the service data is acquired from the block chain, the service data can be stored in the data platform in a preset storage mode. Therefore, when the service data in the block chain needs to be inquired, the corresponding service data can be directly acquired from the data platform, and the data platform adopts a preset storage mode, so that the appointed service data can be inquired more conveniently and rapidly.
The preset storage mode may be that when the service data is stored, the service data is stored in the data platform in a mode of matching with the classification index. For example, the service data is divided according to different category dimensions, the layer-by-layer classification numbers are set, and then the classification indexes are matched with the layer-by-layer classification numbers to store the service data into a designated storage space, so that the retrieval is facilitated.
The processing method of the block chain data provided by the invention is used for acquiring the service data stored in the block chain while generating the block chain; and then the service data is stored in another data platform in a preset storage mode, so that when the data needs to be inquired from the block chain, the corresponding service data can be conveniently inquired from the data platform.
Example two
Fig. 4 is a flowchart illustrating a processing method of blockchain data according to an embodiment of the invention. The embodiment further defines a process of acquiring service data from a block chain based on the method shown in fig. 3. As shown in fig. 4, the method for processing blockchain data includes the following steps:
s410, receiving a notification message carrying the height of the block chain sent by the processing node managing and/or generating the block chain.
In the blockchain network, a processing node that performs data generation and/or management operations on a blockchain is provided, and on the basis that it can acquire blockchain data, the processing node can carry the height of the blockchain in a notification message and send the notification message to the processing device of the blockchain data of this embodiment in a fixed-point sending or broadcasting manner. And after receiving the notification message, the processing device extracts the height of the blockchain carried in the notification message, so as to acquire the generation progress of the current blockchain.
The blockchain height may include the largest block number formed in the current blockchain.
And S420, acquiring the service data from the block chain based on the height of the block chain in the notification message.
After the blockchain height is obtained, the blockchain height in the notification message and the blockchain height corresponding to the previously obtained service data may be referred to, and whether to obtain the service data from the blockchain may be determined, and a corresponding operation may be performed.
When acquiring the service data in the block chain, the service data in the block chain may be acquired locally and synchronously from the processing node that sends the notification message, or the service data may be acquired to a storage platform that stores the block chain data in a designated storage area. For the latter method of acquiring service data, it is necessary for a processing node in the blockchain network to synchronously store the acquired blockchain data onto the storage platform in advance, and to give the service data acquirer the corresponding right to access the data in the storage platform.
For example, based on the blockchain height in the notification message, obtaining the traffic data from the blockchain may include:
if the height of the block chain in the notification message received this time is greater than the height of the block chain in the notification message received last time, acquiring service data corresponding to the height of the block chain in the notification message received this time from the block chain;
and/or the presence of a gas in the gas,
and if the height of the block chain in the notification message received this time is equal to the height of the block chain in the notification message received last time, ignoring the notification message received this time.
Specifically, the timing for the processing node to send the notification message containing the height of the block chain may be performed each time the block chain generates new block data (may be repeatedly sent for multiple times to avoid message loss), or may be periodically sent in time sequence. Correspondingly, when the data acquirer determines whether to acquire service data in the block chain, the data acquirer can compare the currently received notification message containing the block chain height with the block chain height in the last received notification message containing the block chain height, if the former is greater than the latter, the data acquirer indicates that new service data exist in the block chain and can acquire the service data with corresponding height from the block chain according to the currently received block chain height; if the former is equal to the latter, it is stated that no new service data in the block chain is stored in the block chain, and at this time the notification message can be ignored, no processing is done, or a direct idempotent return is made.
It should be noted that, when acquiring service data with a corresponding height from a block chain according to the currently received height of the block chain, only the service data newly added to the height information of the block chain received last time needs to be acquired.
In addition, the step of acquiring the service data stored in the block chain may further include:
and acquiring all data stored in the blockchain or acquiring service data which is stored in the blockchain and is related to the data type stored in the data platform.
Specifically, when service data is acquired from the block chain, all newly added service data can be acquired so as to ensure that the data platform has the full data of the block chain; the service data related to the data type stored in the data platform and stored in the blockchain can also be acquired, and particularly for the data platform used for storing a special type of service data, when the blockchain data is acquired, only the service data related to the data type stored in the service platform can be acquired, so that the data acquisition amount is reduced, and the operation cost is reduced.
And S430, storing the service data into the data platform in a mode of matching with the classification index.
This step may be a refinement of step S320 described above.
Specifically, when data storage is performed, layer-by-layer classification numbers can be set for different types of service data, and then classification indexes are matched for the layer-by-layer classification numbers to store the service data into an appointed storage space, so that retrieval is facilitated.
Based on the method shown in fig. 3, the block chain data processing method obtains the generation progress of the block chain by receiving the block chain height sent by the processing node, thereby determining whether to obtain the service data in the block chain, and executing corresponding operations to avoid unnecessary operations caused by obtaining the service data from the block chain due to no new service data; and when the data platform of the business data is stored, the business data is stored to the data platform in a mode of matching with the classified index, so that the business data in the block chain can be more conveniently inquired from the data platform.
EXAMPLE III
Fig. 5 is a flowchart illustrating a method for processing blockchain data according to an embodiment of the present invention. The embodiment can be used as a supplementary scheme of the method shown in fig. 3 or fig. 4, and adds a processing procedure how to perform correctness verification on the service data in the data platform. As shown in fig. 5, the method for processing blockchain data includes the following steps:
and S510, acquiring the position information of the service data in the block chain from the data platform.
When a third party needs to acquire service data from the data platform, and the authenticity of the data needs to be verified; or the authenticity of the data can be verified according to the position of the service data in the original block chain and the consistency characteristic of the block chain when the authenticity of the service data in the data platform needs to be actively verified according to the setting of the requirements.
In the process of verifying the authenticity of the service data according to the consistency characteristic of the block chain, the service data needs to be traced back to the original position in the block chain. Therefore, for convenience of tracing, when the service data is acquired from the blockchain and stored to the data platform, the position information of the service data in the blockchain can be associated and stored to the data platform.
S520, the service data is subjected to correctness verification by adopting the consistency characteristic of the block chain from the position information of the service data in the block chain.
The consistency of the block chains is characterized in that all data of a previous block are calculated by an irreversible algorithm (usually a Hash algorithm) aiming at two adjacent block chains in the block chains to obtain a check value, and the check value is stored in a block head of a next block; once any data in the previous block is changed in any form, the generated check value is inconsistent with the check value stored in the next block, so that the aim of data non-tampering is fulfilled.
In the checking process, the service data stored in the service platform can be compared with the service data at the same position in the block chain preliminarily, and if the service data are the same, the service data can be basically considered to be real; and the service data at the same position can be replaced by the service data to be verified, and the authenticity of the service data is verified through the consistency characteristic of the block chain.
The block chain data processing method provided by the invention verifies the authenticity of the service data stored in the data platform through the characteristic of consistency of the block chain on the basis of the method shown in fig. 3 or fig. 4 so as to ensure the authenticity and credibility of the data.

and/or the presence of a gas in the gas,
and if the height of the block chain in the notification message received this time is equal to the height of the block chain in the notification message received last time, ignoring the notification message received this time.

and the data verification module 820 is configured to perform correctness verification on the service data by using the consistency characteristic of the blockchain based on the position information of the service data in the blockchain.

The processing device of the block chain data provided by the invention generates the block chain and simultaneously acquires the service data stored in the block chain; and then the service data is stored in another data platform in a preset storage mode, so that when the data needs to be inquired from the block chain, the corresponding service data can be conveniently inquired from the data platform.
