First, technical terms mentioned in the embodiments of the present application will be explained:
block chains: a brand-new distributed database technology is characterized in that benefit parties commonly maintain an increasing directed data record, and the data maintain the data security and time sequence relation through cryptography, privacy protection technology and the like, so that participants are difficult to tamper, repudiate and counterfeit. The alliance blockchain can centralize users with common interests into one blockchain network, and therefore the alliance blockchain is widely applied to various industries including the industries of finance, supply chain, logistics, evidence storage, source tracing and the like.
The prediction machine is a mechanism for transmitting data from the outside of the block chain to the inside of the block chain, and a tool for guaranteeing the authenticity of the data on the chain is provided.
Based on this, the embodiment of the present application provides a service processing system based on a blockchain, which establishes a blockchain network with an alliance blockchain system architecture for data storage and reading.
As shown in fig. 1, the blockchain-based service processing system includes a terminal device 100, a first service module 200, a prediction machine 300, a blockchain network 400, a second service module 500, and a database 600. The terminal device 100 is communicatively connected to the first service module 200 via the gateway device 700. The first service module 200 is communicatively coupled to the blockchain network 400; the prediction machine 300 is in communication connection with the block chain network 400 through network management equipment; the second service module 500 is communicatively coupled to the blockchain network 400; the second service module 500 is communicatively coupled to a database 600.
The first service module 200 is used to upload the first financial transaction data to the predetermined blockchain network 400.
The second service module 500 is configured to synchronize data information in the blockchain network 400 to the database 600, so that the database 600 provides the data information to the terminal device 100 for query. Database 600 is set to read-only mode. When the terminal device 100 needs to uplink the service data, the received first financial service data is sent to the first service module 200 through the gateway device 700 in the form of an http request, and the first service module 200 processes the first financial service data by calling an interface corresponding to the alliance blockchain, and uploads the first financial service data to the blockchain network 400.
Since the database 600 is data information in the real-time synchronized blockchain network 400, the data information in the database 600 is traceable, transparent, and reliable. At this time, the access to the data information and the first uplink for the financial service data can be performed synchronously, so that the efficiency of the access processing for the financial service under the system of the present application is higher compared to the traditional uplink and data access from the blockchain network 400.
On one hand, an embodiment of the present application further provides a service processing method based on a block chain, which is applied to the terminal device 100, and as shown in fig. 2, the method includes:
step S110, receiving first financial service data to be processed.
Step S120, sending the first financial service data to a preset first service module 200; the first service module 200 is configured to upload the first financial transaction data to the predetermined blockchain network 400.
It should be noted that the blockchain network 400 adopts the blockchain network 400 with the alliance blockchain architecture, and the first service module 200 is an interface corresponding to the alliance blockchain and is used for uploading the first financial service data of the terminal device 100 to the blockchain network 400. In some embodiments, the first service module 200 may upload the first financial transaction data to the blockchain network 400 after performing preprocessing, such as security check, data integration, and the like.
It should be noted that the first financial transaction data represents the original data that the user needs to upload.
And step S130, receiving a query request.
Step S140, obtaining first data corresponding to the query request according to the query request and a preset database 600; the database 600 stores data information, and the data information is synchronized from the blockchain network 400 through a preset second service module 500.
It should be noted that the first data represents data required by the user to issue the query request. In some embodiments, the first financial transaction data is directly stored in the blockchain network 400 without conversion, and the first data is corresponding data information; in other embodiments, to ensure the security of the service data, the first financial service data is encrypted or otherwise securely processed, and at this time, the data information is the processed service data. The first data corresponds to original data of the data information.
Therefore, by setting the database 600 to synchronize the data information in the blockchain network 400, it is ensured that the sources of the data information acquired from the database 600 are all from the publicly reliable blockchain network 400, and meanwhile, the efficiency of accessing the financial service data by the user is improved by using the database 600 which has higher access efficiency than the blockchain.
It is understood that, as shown in fig. 3, for the terminal device 100, the step S140 includes:
and step S141, obtaining third data matched with the query request according to the query request.
Step S142, extracting a data storage position and second data from the third data; and the second data is obtained by calculation through a preset safety verification method.
It should be noted that the security verification method may be calculated in a hash manner. The data storage position represents position information of original service data storage corresponding to the second data, and the original service data can be acquired according to the position information. The original business data (first financial business data) corresponding to the second data can be stored in the private server, and the right is set for the access user, so that the sensitive information can be made public and reliable in traceability and can have certain confidentiality.
And S143, requesting to obtain second financial service data according to the data storage position.
It should be noted that the second financial transaction data represents the original transaction data obtained from the server or database 600 in which the first financial transaction data is stored. Since the information in the slave blockchain network 400 is truly reliable, if the original transaction data is not changed, the second financial transaction data should be equal to the first financial transaction data, and the second financial transaction data is available.
And step S144, obtaining a verification value of the second financial service data through a security verification method, and matching the verification value with the second data.
It should be noted that, when the verification value obtained by the second financial transaction data using the same security verification method matches the second data, it indicates that the original data stored in the blockchain network 400 corresponding to the second data is not changed, and is true and reliable.
And step S145, if the matching is successful, outputting the second financial service data as the first data.
It can be understood that, as shown in fig. 4, the block chain-based service processing method of the present application is applied to the first service module 200, and the method includes:
and step S210, receiving first financial service data.
The first financial transaction data is uploaded to the predetermined blockchain network 400.
Uploading the first financial transaction data to the predetermined blockchain network 400 includes:
and step S221, acquiring a data storage position of the first financial service data.
It should be noted that the data storage location, that is, the location where the first financial service data is stored, can establish a relationship between the location where the first financial service data is stored and the data information in the blockchain network 400 according to the data storage location.
Step S222, performing hash processing on the first financial service data to obtain second data.
It should be noted that the hash is not reversible, so that the reliability of the service data can be further improved.
Step S223, binding the second data and the corresponding data storage location to obtain third data, and uploading the third data to the blockchain network 400.
It should be noted that, by performing hash processing on the first financial service data, the specific content of the data information in the blockchain is kept secret, so that the original service data can keep its sensitivity and is not abused; meanwhile, tracking and tracing can be carried out to ensure the reliability of the original service data. It should be noted that the third data is synchronized to the database 600 through the second service module 500, so that the query efficiency is higher when the terminal device 100 initiates the query request.
It is understood that uploading the first financial transaction data to the predetermined blockchain network 400 further includes, before step S223:
first authentication data is requested from the preset prediction machine 300 according to the second data.
It is noted that the first authentication data may be obtained by establishing network communication with the prediction machine 300 through the gateway apparatus 700.
At this time, when the first authentication data is authenticated, step S223 is performed.
It should be noted that, in some embodiments, the first verification data is not stored in the blockchain network 400, such as company information of a company, and therefore the first verification data needs to be obtained by the prediction machine 300 for verification.
It can be appreciated that the predictive engine 300 invokes an external trusted centralized system or obtains the first verification data from a third party blockchain system through a cross-chain technique.
It can be understood that, as shown in fig. 5, the method applied to the first service module 200 further includes:
step S231 receives a data processing request.
Note that the data processing request is obtained by the gateway apparatus 700 for the terminal apparatus 100.
Step S232, according to the data processing request, obtain the corresponding data information from the blockchain network 400.
Step S233, acquiring the first processing data from the preset predicting machine 300 according to the data information.
It should be noted that, in some embodiments, when a data processing request is made, the validity of data, such as the validity of company information, needs to be verified. Thus, the first processed data can be obtained by the prediction machine 300.
Step S234, according to the data processing request, the first processed data is processed to obtain second processed data.
Step S235, the second processing data is pushed to the predicting machine 300, so that the third party organization obtains the second processing data through a monitoring manner.
It should be noted that the third-party organization can quickly acquire the second processing data through a monitoring mode, so that the processing efficiency of the whole system can be improved. At this time, when the financial business data is processed and interaction with a third-party organization is needed, the method can be more efficient.
It is noted that the data processing request may be an asset transfer in some embodiments. The forecast machine 300 carries out excess judgment or rechecking processing on the quota of the assets.
It is understood that execution of the first service module 200 may be handled by a smart contract. It should be noted that the different types of the first financial transaction data have different verification information or different transaction logics, and therefore, respective intelligent contracts are correspondingly set to complete the uplink.
It can be understood that, as shown in fig. 6, the present application further provides a service processing method based on a block chain, which is applied to the second service module 500, and the method includes:
synchronizing uplinked data information from the blockchain network 400 to a predetermined database 600; wherein the database 600 provides data information to the terminal device 100 for querying.
Synchronizing uplinked data information from the blockchain network 400 to the predetermined database 600 includes:
step S310, the monitoring module 510 monitors the blockchain network 400 in real time to obtain data information corresponding to the added blocks of the blockchain network 400.
Step S320, the listening module 510 sends the data information to the message service module 520.
Step S330, the message service module 520 sends the data information to the database 600 for storage in an asynchronous processing manner.
Therefore, by setting the snoop module 510, the data information on the blockchain can be synchronized to the database 600 in real time. Meanwhile, the message service module 520 is arranged to realize asynchronous processing, and the synchronous efficiency is improved.
