In the financial investment field, the personal ability of the investment manager directly relates to the quality of the investment income, so that the management mechanism expects to acquire real and comprehensive information of the investment manager in time when the investment manager is used and the consignee selects the cooperative investment manager. However, at present, relevant information of an investment manager is scattered in each organization, part of information is stored in a management mechanism which the investment manager has already spent, part of information is stored in a cooperated trusted organization, and the information of the investment manager is scattered and stored in each organization, so that the information of the investment manager cannot be conveniently and rapidly obtained by each organization. In addition, due to the privacy requirement of the investment manager information, the investment manager information cannot be directly reported to the blockchain network by adopting a mode of storing application scenes by a general blockchain.

Based on this, in the present exemplary embodiment, a blockchain-based data storage method is provided first, and is applied to a financial institution platform, where a client, a blockchain link point, and a platform database are deployed, where the blockchain-based data storage method of the present disclosure may be implemented by using a server, and where the method described in the present disclosure may be implemented by using a terminal device, where the terminal described in the present disclosure may include a mobile terminal such as a mobile phone, a tablet, a notebook, a palm computer, a personal digital assistant (Personal Digital Assistant, PDA), and a fixed terminal such as a desktop computer. FIG. 1 schematically illustrates a schematic diagram of a block chain based data storage method flow in accordance with some embodiments of the present disclosure. Referring to fig. 1, the blockchain-based data storage method may include the steps of:

step S110, receiving data uploading operation of a target user for target data by a client, and generating a data identification code of the target data; the target data includes private information of the financial institution-related user.

Step S120, the client stores the target data and the data identification code to the platform database, and generates a data storage event.

Step S130, uploading the data storage event to a block chain node by the client, and synchronizing the data storage event to a block chain network through the block chain link point so that each block chain node in the block chain network can make consensus on the data storage event.

According to the blockchain-based data storage method in the present exemplary embodiment, on one hand, by deploying the blocknodes and the storage nodes in the financial institution platform and forming the industry data standard, centralized storage of target data and security of data storage can be effectively ensured. On the other hand, by adopting the storage mode, the comprehensive and intelligent management of the target data can be realized, and each financial institution does not need a self-built system to store the target data; when each financial institution needs to use the target data, the storage mode can ensure that each institution conveniently obtains real and comprehensive data, and can effectively improve timeliness of data obtaining.

Next, a block chain based data storage method in the present exemplary embodiment will be further described.

Personnel involved in the block chain based data storage application scenario include investment managers, sponsors, management, trusted and regulatory authorities, and the like. Specifically, the main responsibilities of the different personnel are as follows: the investment manager may be a professional engaged in investment management at an investment management institution. The sponsor may be an organization that manages and maintains information for each organization in the blockchain network, may be used to provide basic services, facilitate the investment manager to report personal basic information, and may view relevant reports of the investment manager, etc., based on the investment manager's authorization. The pipe throwing mechanism can carry out examination and evaluation on investment managers of the mechanism regularly or temporarily according to supervision requirements, and report examination and evaluation reports; the assessment report can be sent to the appointed mechanism according to the data extraction application of the appointed mechanism; and the relevant reports of the investment manager can be checked according to the authorization of the investment manager. The trusted authority can carry out assessment and evaluation on the cooperative investment manager regularly or temporarily according to the supervision requirement, and report an assessment report; the report can be sent to the appointed mechanism according to the data extraction application of the appointed mechanism; the relevant reports of the investment manager can also be checked according to the authorization of the investment manager. The supervision mechanism can supervise the investment manager and upload supervision reports; the report can be sent to the appointed mechanism according to the data extraction application of the appointed mechanism; the relevant reports of the investment manager can also be checked according to the authorization of the investment manager.

In step S110, the client receives a data uploading operation of the target user for the target data, and generates a data identification code of the target data; the target data includes private information of the financial institution-related user.

In some exemplary embodiments of the present disclosure, the target user may be a user of each financial institution uploading the target data, e.g., the target user may be the investment manager himself, or may be a relevant business operator user uploading the assessment report by a administration, trusted authority, or regulatory agency. The target data may be information related to the investment manager, for example, privacy data such as assessment report data of the investment manager by other institutions; in addition, the target data may be other data with higher privacy degree, and the specific data type and data content of the target data are not limited in any way in the disclosure. The data uploading operation may be an operation of uploading target data by the target user through a client of the financial institution. The data identification code may be an identification code uniquely corresponding to the uploaded target data.

Referring to fig. 2, fig. 2 schematically illustrates an interaction flow diagram between parties in data storage according to an exemplary embodiment of the present disclosure. In the present disclosure, a sponsor and other financial institution platforms are each deployed with block link points and a platform database (i.e., local storage nodes), and data storage is performed on target data in a manner of "storage nodes+block nodes"; the local storage node can be a data storage device for storing report data, and each organization can ensure that the data files stored in the platform database are not lost by setting disaster recovery strategies. The investment manager and other participants can perform data uploading operation of target data through clients of the financial institution platform. The clients of the financial institution platforms can provide user interaction interfaces, so that a target user can conveniently perform data storage operation or data acquisition operation based on the user interaction interfaces.

The investment manager 211 may first upload personal basic information to the blockchain network 250 through clients provided by the sponsor facility 210 before other facilities upload investment manager-related reporting information, consensus the investment manager's personal information in the blockchain network. After the personal basic information of the investment manager is uploaded to the blockchain network, the client of the financial institution platform can receive the data uploading operation of the target user aiming at the target data, and relevant report data of the investment manager is stored in the platform database corresponding to each financial institution. For example, taking a business operator whose target user is a management entity as an example, the target data may be a performance evaluation report of the management entity to the investment manager. After the performance evaluation report corresponding to the investment manager is generated by the management agency, a management agency service personnel can upload the performance evaluation report of the investment manager through a client of the management agency, and after the performance evaluation report is successfully stored in a platform database of the management agency, the management agency can generate a data identification code uniquely corresponding to the performance evaluation report. And after the investment manager stores the personal basic information, each organization can upload the assessment report through the respective client, and the uploading assessment report among the organizations is independent and has no sequence relation in the process. For example, the regulatory agency 230 and the trusted authority 240 may each upload relevant information of the investment manager to their respective platform databases via the clients of the regulatory agency and the clients of the trusted agency, and generate a data identification code uniquely corresponding to the stored data.

According to some exemplary embodiments of the present disclosure, a target data name of target data is determined, and whether historical data with the same data name as the target data name exists in a platform database is judged; if there is history data, determining whether to receive the target data; if it is determined that the target data is received, a data identification code is generated from the target data. The history data may be data having the same data name as the target data.

The target data uploading contract can be suitable for various institutions such as a trusted institution, a management institution, a supervision institution, a sponsoring institution and the like to upload various report data related to an investment manager. In an actual application scenario, various institutions may periodically perform assessment on investment managers, and upload and store data of generated assessment reports.

Referring to fig. 3, fig. 3 schematically illustrates a flow chart corresponding to a target data upload contract according to an exemplary embodiment of the present disclosure. Taking a service person of the pipe throwing mechanism as an example to upload target data through a client of the pipe throwing mechanism for explanation. In step S301, the salesman may upload target data (i.e., evaluation report data) through the organization client. In step S302, the facility client may check whether the assessment report of the current period has been uploaded. In step S303, it is determined whether the report has been uploaded as a result of the upload. Since other problems such as data errors may exist in the uploaded report data during the data uploading process, the report data may be uploaded again. In step S304, if the report data of the present period has been uploaded, it may be determined whether to upload the report file of the present period again. In step S305, it may be determined whether the result is uploaded again. If the report data does not need to be uploaded again, the whole data storage flow is ended. In step S306, if the current report data is not uploaded, a unique data identification code corresponding to the report data may be calculated.

The data upload contract may contain a plurality of data items such as unique codes of investment managers, report types, report unique codes, report start dates, report end dates, reporting agency codes, etc., wherein the report types may include temporary reports and periodic reports. The periodic report may be an evaluation report corresponding to the performance of the investment manager being assessed by the relevant institution for a certain period of time, for example, the financial institution may assess the investment manager for a month, quarter, year. Specifically, specific descriptions of the respective data items are shown in table 1.

TABLE 1

In step S120, the target data and the data identification code are stored to the platform database by the client, and a data storage event is generated.

In some exemplary embodiments of the present disclosure, the platform database may be a database deployed locally on financial institution platforms of the institutions, each of the financial institution platforms corresponding to one of the platform databases for storing report data uploaded by the operators of each institution via the clients. The data storage event may be a storage event that uploads report data through an organization client and successfully stores the report data to a platform database.

After the data identification code corresponding to the target data is generated, the target data and the data identification code corresponding to the target data can be stored in a platform database corresponding to the financial institution platform so as to generate a data storage event corresponding to the target data. In step S307, the financial institution platform may store the report file in a local database.

According to some exemplary embodiments of the present disclosure, a data storage operation is performed with respect to target data, and it is determined whether the target data is stored to a platform database; if the target data is stored in the platform database, generating a data storage event according to the target data and the data identification code; if the target data is not stored in the platform database, an upload failure message is returned. The data storage operation may be an operation process of storing target data to a platform database. The upload failure message may be an event message corresponding to the unsuccessful storage of the target data to the platform database.

When the institution financial institution platform receives the data uploading operation of the target user, the data storage operation can be executed for the target data, and whether the target data is stored in the platform database is judged. If the target data is already stored in the platform database, the financial institution platform may generate a data storage event based on the target data and the data identification code to identify that the target data has been successfully stored to the platform database. If the target data is not stored in the platform database, an upload failure message is returned to the target user.

In step S308, the financial institution platform may determine whether the local storage of the report file is successful. In step S309, if the report data is not successfully stored in the local database, a service person who uploaded the report data may be notified of a message that the report data has failed to be uploaded. In step S310, if the report data is successfully stored in the local database, the successfully stored data result is uploaded to the blockchain node, and the financial institution platform encapsulates the data identification code generated according to the target data and the data storage event into a data block, and uploads the data block to the blockchain network 250 through the blockchain link to achieve consensus on the current data storage event.

In step S130, the client uploads the data storage event to the blockchain node and synchronizes the data storage event to the blockchain network through the blockchain link points, so that each blockchain point in the blockchain network has a consensus on the data storage event.

In some example embodiments of the present disclosure, the blockchain nodes may be nodes for storing data storage events, with the blockchain nodes deployed by the financial institution platforms. The blockchain network may be used to synchronize data storage events of the number of tag data stored in blockchain nodes of the respective organization platform. After the institution platform generates the data storage event, the data storage event may be uploaded to the blockchain node, and the data storage event may be synchronized to the blockchain network through the blockchain link point, so that consensus is achieved between the blockchain nodes in different financial institution platforms for the data storage event. The blockchain node may receive blockchain platform messages to synchronize data in the blockchain network.

By the block chain-based data storage method, the data of all dimensions of the investment manager can be collected to form a full-dimension data set containing the whole careers of all the investment managers. The storage process ensures the data privacy security of investment manager information data by means of arranging the blockchain node and the local storage node in each organization. As will be readily appreciated by those skilled in the art, when the target user performs data storage through the regulatory agency 230 and the trusted authority 240, the overall data storage process is the same as the data storage performed by the target user through the client of the administration agency 220, which is not described in detail in this disclosure.

Based on this, in the present exemplary embodiment, there is first provided a blockchain-based data acquisition method, and fig. 4 schematically shows a schematic diagram of a blockchain-based data acquisition method flow according to some embodiments of the present disclosure. Referring to fig. 4, the blockchain-based data acquisition method may include the steps of:

step S410, receiving data uploading operation of a target user for target data by a client, and generating a data identification code of the target data; the target data includes private information of the financial institution-related user.

Step S420, the client stores the target data and the data identification code to the platform database, and generates a data storage event.

Step S430, uploading the data storage event to a blockchain node by the client, and synchronizing the data storage event to a blockchain network through the blockchain link point, so that each blockchain node in the blockchain network performs consensus on the data storage event.

Specifically, the data items in the intelligent contract for acquiring the target data mainly comprise fields such as unique codes of investment managers, report types, report start dates, report end dates, receiving mechanism codes, application validation dates, application expiration dates and the like. The specific meaning of the above fields is shown in table 2.

TABLE 2

In step S450, a data acquisition request is broadcast by the blockchain network to the second organization platform to determine a data transmission platform associated with the data acquisition request from the second organization platform.

In some exemplary embodiments of the present disclosure, the second facility platform may be all other facility platforms except the sponsoring facility platform, and the second facility platform may include a administration facility platform, a regulatory facility platform, a trusted facility platform, and the like. The data transmission platform may be an organization platform storing target data corresponding to the data acquisition request.

Referring to fig. 6, after uploading the data acquisition request to the blockchain network in step S606, the blockchain network 510 may broadcast the data acquisition request to the second organization platform. In fig. 5, blockchain network 510 may send data acquisition requests to a second facility platform, including a cast facility platform 530, a trusted facility platform 540, a regulatory facility platform 550, and the like; the pipe-casting mechanism platform 530 includes a pipe-casting mechanism platform a, a pipe-casting mechanism platform B, a pipe-casting mechanism platform N, and so on. When the second institution platform receives the data acquisition request, the data transmission platform can be determined according to the related information of the target data contained in the data acquisition request, so that the target data can be acquired from the data transmission platform. For example, in fig. 5, the data transmission platform includes a pipe feeding mechanism platform B and a trusted mechanism platform N.

A specific procedure of determining a data transmission platform from the second organization platform is as follows, referring to fig. 7, fig. 7 schematically illustrates a flowchart corresponding to a smart contract for transmitting target data according to an exemplary embodiment of the present disclosure. In step S701, the second organization platform receives a data acquisition request sent by a blockchain network. In step S702, after the second institution platform receives the data acquisition request, the data acquisition request may be subjected to parsing processing. In step S703, after the data acquisition request analysis processing is finished, each second mechanism platform may determine whether there is report data to be provided in the mechanism platform. If a certain second organization platform contains report data, the second organization platform is determined as a data transmission platform.

In step S460, the data transmitting platform determines report data according to the data acquisition request, and transmits the report data to the data receiving platform corresponding to the receiving platform code through the private data transmission channel. The report data may be data related to an assessment report of an investment manager related to the data acquisition request. The data receiving platform may be an institutional platform that receives report data.

In some exemplary embodiments of the present disclosure, if report data associated with a data acquisition request is included in the data transmission platforms, each data transmission platform determines report data corresponding to the data acquisition request from the local database, and when the report data is determined, the report data may be transmitted to the data reception platform. Referring to fig. 5, the data receiving platform in fig. 5 is a regulatory agency platform B, and thus, the regulatory agency platform B may receive target data transmitted by the administration agency platform B and the trusted agency platform N.

According to some exemplary embodiments of the present disclosure, determining, by a data transmission platform, whether report data is in a valid time interval corresponding to a data acquisition request; if the report data is in the effective time interval, acquiring the report data from the association database according to the data acquisition request; and establishing a private data transmission channel between the data receiving platform and the data receiving platform, and sending report data to the data receiving platform through the private data transmission channel. The valid time interval may be a time range interval corresponding to report data to be transmitted in the data acquisition request. For example, the validity time interval of the report data to be acquired this time may be data at a cutoff from 2020-08-00:00:00 to 2020-10-08-00:00:00. The association database may be a local database corresponding to the data transmission platform. The private data transmission channel can be a data transmission channel adopted when the data transmission platform and the data receiving platform carry out data transmission, namely, a private chain between a block chain node corresponding to the data transmission platform and a block chain node corresponding to the data receiving platform, and the security of data transmission can be ensured by adopting the private data transmission channel to carry out data transmission.

Referring to fig. 7, in step S704, when the second mechanism platform determines that the mechanism has report data to be provided, it is further determined whether the report data in the mechanism platform is within a valid time interval corresponding to the data acquisition request. In step S705, the data transmission platform may determine whether the report data is within the valid time interval, and if the report data stored in the mechanism platform is not within the valid time interval, the process of transmitting the target data is ended. In step S706, if the report data stored in the organization platform is within the valid time interval, the report data is extracted from the platform database according to the data acquisition request. After acquiring the report data from the platform database, the data transmission platform may establish a private data transmission channel with the data reception platform in step S707. In step S708, it is determined whether the private data transmission channel between the data sending platform and the data receiving platform is successfully established, and if the private data transmission channel is not successfully established, the process returns to step S707, and the private data transmission channel between the data sending platform and the data receiving platform is re-established until the private data transmission channel is successfully established. In step S709, after the private data transmission channel between the data transmission platform and the data reception platform is established successfully, the data transmission platform may transmit report data to the data reception platform through the private data transmission channel.

According to some exemplary embodiments of the present disclosure, data verification processing is performed on report data by a data receiving platform to generate a data verification result; and if the data check result is not passed, acquiring report data from the association database according to the data acquisition request again. The data verification process may be a verification operation process performed by the data receiving platform on the report data received from each data transmitting platform. The data verification result may be a processing result corresponding to the data verification process.

Because report data of a certain investment manager may be stored in a plurality of institution platforms, the data acquisition request corresponds to a plurality of data transmission platforms, and after the data receiving platform receives the report data sent by the plurality of data transmission platforms, the data receiving platform can perform data verification processing on the part of report data and generate a data verification result for the report data. Referring to fig. 7, in step S710, the data transmission platform may wait for a data verification result of the data reception platform. In step S711, if the data verification result is failed, step S706 is re-executed, and report data is acquired from the local database of the organization platform again according to the data acquisition request.

Specifically, the report data transmission contract of the investment manager includes data items as shown in table 3, and the report data transmission contract mainly includes fields such as an investment manager unique code, a report type, a report file unique code, a report start time and a report end time, a report receiving mechanism code, and a report transmitting mechanism code.

Because the data acquisition request contains the receiving platform code, the second mechanism platform can analyze and extract the receiving platform code in the data acquisition request, and judge whether a certain second mechanism platform is a data receiving platform according to the receiving platform code. And if the second mechanism platform judges that the data acquisition request does not contain the data to be received by the mechanism platform, namely the second mechanism platform does not serve as a data receiving platform, ending the data transmission flow.

In step S804, if a certain second mechanism platform is a data receiving platform, that is, if there is report data to be received by the mechanism platform in the current data acquisition request, it is determined whether the data to be received at this time is within a valid time interval included in the data acquisition request. In step S805, the data receiving platform determines whether the determination result is within the valid time, and if the data to be received by the data receiving platform is not within the valid time interval, the entire data receiving process is ended. In step S806, if the data to be received by the data receiving platform is within the valid time interval, a private data transmission channel is waiting to be established with the data sender.

In step S807, the data receiving platform may determine whether the private data transmission channel with the data sending platform is established successfully, and if the private data transmission channel is not established successfully, step S806 is repeated until the private data transmission channel is established successfully. In step S808, when the private data transmission channel is established successfully, the data receiving platform receives the report data through the private data transmission channel.

In step S809, after receiving the report data, the data receiving platform may calculate a corresponding report unique code according to the received report data, and perform a comparison check process on the calculated report unique code and the report unique code of the received report data. In step S810, the processing result of the comparison check is determined, and the report check result is fed back to the data transmission platform. In step S811, the data receiving platform may check whether all report data corresponding to the current data acquisition request is successfully received.

In step S812, the data receiving platform determines whether all report data is received as a result of success; if there is unsuccessfully received data, the process returns to step S804 to determine whether the unsuccessfully received report data is still within the valid time interval. In step S813, after receiving all the report data, the data receiving platform uploads the report receiving result to the blockchain network, and feeds back the result of successful receiving of all the report data to the blockchain network.

Specifically, the data items involved in the smart contract for receiving the target data include fields such as investment manager unique code, report type, report file unique code, report start date, report end date, report receiving organization code, report transmitting organization code, and the like, as shown in table 4.
