The business data identifier is used to uniquely identify the business data. The business data may specifically be order information or order data. The business data modification request is a request used to trigger a business data modification operation, and is used to instruct the server to store the modified business data in the blockchain to modify the target business data. The business data modification request may carry modified business data, that is, business data obtained by modifying the target business data.

Specifically, the first terminal displays the business data to be modified to the modifier through the modifier operation interface, and detects in real time a preset data submission operation triggered by the modifier on the displayed business data to be modified. When the preset data submission operation is detected, the first terminal obtains the business data pre-entered or pre-selected by the modifier for the target business data as the modified business data, and determines that the modified business data is stored in the blockchain The revised business data. The first terminal generates a service data modification request according to the modified service data, and sends the generated service data modification request to the server.

In one of the embodiments, the first terminal detects a preset trigger condition in real time, and when the preset trigger condition is detected, it triggers generation of a service data query request carrying a service data identifier according to the detected preset trigger condition, and generates The business data query request is sent to the server to query the business data corresponding to the business data identifier and to be modified from the blockchain by means of the server.

S204: Determine the modified business data according to the business data modification request, store the modified business data in the blockchain, and generate a business data review instruction according to the modified business data.

The business data review instruction is an instruction used to trigger the business data review operation, which is used to instruct the second terminal to display the modified business data to be reviewed to the auditor, and obtain the review opinion triggered by the auditor on the modified business data data.

Specifically, the server parses the business data modification request to obtain the modified business data, and performs an in-chain operation on the modified business data, so as to store the modified business data in the blockchain, so as to realize the target business data Modifications. When the modified business data is written into the blockchain, the server generates corresponding business data review instructions according to the modified business data.

In one of the embodiments, when the modified business data is successfully written into the blockchain, the server generates a business data review instruction according to the modified business data. The server may generate a business data review instruction carrying modified business data, and may also generate a business data review instruction carrying a business data identifier.

S206: Determine the second terminal according to the service data identifier, send the service data review instruction to the second terminal, and receive review opinion data fed back by the second terminal in response to the service data review instruction.

The review opinion data is used to characterize the review opinions of the auditor on the modified business data displayed on the second terminal, and may specifically include the review passed and the review failed. According to the audit opinion data, it can be determined whether the auditor agrees with the modifier to modify the modified business data.

Specifically, the server determines the second terminal according to the service data identifier, and sends the generated service data review instruction to the determined second terminal. The second terminal determines the modified business data to be reviewed according to the received business data review instruction, displays the modified business data to the auditor through the auditor operation interface, and detects the revised business data displayed by the auditor in real time The triggered audit opinion data, and then the detected audit opinion data is fed back to the server.

In one of the embodiments, determining the second terminal according to the business data identifier and sending the business data review instruction to the second terminal includes: determining the auditor account based on the business data identifier; sending the business data review instruction to log in with the reviewer account The second terminal of the business data review instruction is used to instruct the second terminal to display the modified business data and obtain the review opinion data corresponding to the modified business data.

The auditor account refers to an account pre-registered by the auditor and used to log in to the second terminal. The auditor account may specifically be an account used to log in to a specific client, browser, webpage, or system by means of the second terminal. The auditor account number can be used to uniquely identify the auditor, which can be a character string composed of at least one of numbers, letters, and symbols.

Specifically, when generating the business data review instruction, the server queries the pre-configured auditor account in the database according to the business data identifier, and determines the second terminal to log in with the auditor account, and then sends the generated business data review instruction to The determined second terminal. The second terminal determines the modified business data to be reviewed according to the received business data review instruction, displays the modified business data to the auditor, and obtains the review opinion data triggered by the auditor on the displayed modified business data .

In one of the embodiments, the server searches the database for an auditor ID matching the service data ID according to the service data ID, and searches the pre-configured auditor account according to the auditor ID.

In one of the embodiments, when an auditor ID matching the service data ID is queried, the server queries the database for the pre-configured second terminal ID according to the auditor ID, and sends the service data audit instruction to the second terminal Identify the corresponding second terminal.

In one of the embodiments, the second terminal parses the received business data review instruction to obtain the modified business data to be reviewed, displays the modified business data to the auditor, and obtains the auditor’s modified business data Triggered review opinion data, and feedback the review opinion data to the server.

In one of the embodiments, receiving the review opinion data fed back by the second terminal for the business data review instruction includes: receiving the review data query request corresponding to the business data identifier sent by the second terminal; and downloading the review data from the blockchain according to the review data query request Find the modified service data corresponding to the service data identifier in the, send the modified service data to the second terminal for display, and receive the review opinion data fed back by the second terminal for the modified service data.

The audit data query request is a request used to trigger the audit data query operation, and is used to instruct the server to query and feed back the revised business data to be audited.

Specifically, the server sends the generated service data review instruction to the second terminal determined according to the service data identifier. The second terminal parses the service data audit instruction to obtain a service data identifier, generates an audit data query request according to the service data identifier, and sends the generated audit data query request to the server. The server determines the business data identifier according to the received audit data query request, and finds the modified business data corresponding to the business data identifier in the blockchain according to the business data identifier, and then sends the found modified business data to The second terminal. The second terminal displays the received modified business data to the auditor through the auditor operation interface, and detects the audit opinion data triggered by the auditor on the displayed modified business data, and then feeds back the detected audit opinion data To the server.

In one of the embodiments, the server searches the blockchain for the latest version of the business data corresponding to the business data identifier according to the audit data query request, as the modified business data. The server searches for the business data corresponding to the business data identifier in the blockchain, and determines the version number (or entry time) of each business data found, and then selects the latest version number (or entry time) from the searched business data The latest or most recent business data is used as the modified business data.

In one of the embodiments, the server searches the blockchain for business data corresponding to the business data identifier and whose review status is pending review (or unreviewed) from the blockchain according to the review data query request, as the modified business data. The server searches for the business data corresponding to the business data identifier in the blockchain, and filters out the business data whose review status is pending review from the business data found, as the modified business data.

In one of the embodiments, the server searches for the business data corresponding to the business data identifier in the blockchain, and filters out the latest version of the business data whose review status is pending review (or unreviewed) from the found business data , As the revised business data.

S208: Use the review opinion data as the review status of the modified business data, and store it in the blockchain in association with the modified business data.

Specifically, when receiving the review opinion data fed back by the second terminal, the server uses the received review opinion data as the review status of the modified business data, and stores the review status in association with the modified business data in the block Chain. It can be understood that when receiving the review opinion data fed back by the second terminal for the modified business data, the server determines the review status of the corresponding modified business data according to the review opinion data, and compares the determined review status with the modified business data The data is stored in the blockchain.

In one of the embodiments, the server associates the audit status and the modified business data with the corresponding version number when stored in the blockchain, and stores the modified business data in the blockchain according to the business data modification request The version number corresponding to the time can be the same or different.

In one of the embodiments, when the review opinion data fed back by the second terminal is received and the review opinion data is approved, the server determines the review status of the modified business data as approved, and will indicate the approved review The status and modified business data are stored in the blockchain in association with each other. When the review opinion data fed back by the second terminal is received, and the review opinion data is that the review failed, the server determines the review status of the modified business data as the review failed, and will indicate the review status and the revised review status that the review failed The business data is stored in the blockchain.

In one of the embodiments, when the review opinion data fed back by the second terminal for the modified business data is received, the server uses the received review opinion data as the review status of the modified business data, and obtains the current system time as the review Time stamp, and then store the audit time stamp, audit status, and modified business data in the blockchain.

S210: If a business data query request carrying a business data identifier sent by the first terminal is received, the review status of the modified business data is searched from the blockchain according to the business data query request.

The business data query request is a request used to trigger the business data query operation. The service data query request may carry the service data identifier.

Specifically, the first terminal detects the preset trigger condition in real time, and when the preset trigger condition is detected, determines the service data identifier according to the detected preset trigger condition, generates the service data query request according to the determined service data identifier, and sends The generated business data query request is sent to the server. When receiving the business data query request sent by the first terminal, the server searches the blockchain for the modified business data corresponding to the business data identifier and the review status of the modified business data according to the business data query request. The preset trigger condition, for example, detects a preset trigger operation, or detects that the current system time is consistent with the preset trigger time, or the preset duration is reached after the current business data query request is triggered. The preset trigger operation is, for example, a trigger operation such as clicking, sliding, or pressing a preset trigger control. The preset trigger time and preset duration can be customized according to the actual situation.

It can be understood that if the server receives the service data query request sent by the first terminal after associating the audit status and the modified service data into the blockchain, at this time, the latest version of the service data corresponding to the service data identifier is The revised business data. According to the received business data query request, the server searches the blockchain for the review status corresponding to the latest version of the business data corresponding to the business data identifier.

In one of the embodiments, the first terminal periodically triggers the service data query request according to a pre-configured preset trigger condition, and sends the triggered service data query request to the server. The server detects the service data query request sent by the first terminal in real time, and if it receives the service data query request carrying the service data identifier sent by the first terminal, it extracts the service data identifier from the received service data query request, and extracts it according to the extracted The business data identifier of Query the latest version of business data.

S212: When the found review status is the review failed, search for the target business data of the latest version from the blockchain according to the business data identifier and the review status is the target business data that has passed the review, and feed back the target business data to the first terminal.

The latest version of the business data refers to the business data with the latest version number, or the business data with the latest or recent entry into the chain (that is, the latest or recent entry into the chain), and the entry time refers to the business data written into the blockchain time. The audit status includes approved status and failed audit status.

Specifically, when the review status corresponding to the modified business data found in the blockchain is the review failed, the server searches the blockchain for the business data identifier carried in the business data query request. The business data corresponding to the data identification, select the latest version of the business data from the searched business data and the audit status is approved as the searched target business data, and feed back the searched target business data to the first terminal . The server separately determines the audit status and version number (or the time of entering the chain) of each business data found, and selects the audit status from the found business data as approved and the latest version number (or the latest entry time) Business data, as target business data.

It can be understood that when the review status corresponding to the found modified business data is the review failed, the target business data queried by the server in the above manner is the business data to be modified corresponding to the modified business data. It is the business data before the modification corresponding to the modified business data.

In one of the embodiments, when the found audit status is that the audit failed, the server finds one or more pieces of business data corresponding to the business data identifier in the blockchain. When multiple pieces of business data are found, the server selects, from the multiple pieces of business data, the business data of the latest version and whose review status is approved as the target business data. When a piece of business data is found, the server can use the piece of business data as the target business data found, and can also further determine whether the review status of the piece of business data is approved. A piece of business data is used as the found target business data. It is understandable that if the target business data corresponding to the business data identifier is not found in the blockchain, the server will feed back to the first terminal prompt information indicating that the business data query has failed.

In one of the embodiments, the service data found by the server from the blockchain carries the audit status and version number (or the time of entering the chain). The server extracts the corresponding review status and version number (or link time) from each business data found.

In one of the embodiments, the server stores the corresponding review status and version number (chain access time) in the blockchain for each business data that has been written into the blockchain. The server searches for the business data corresponding to the business data identifier from the blockchain according to the business data query request, as well as the review status and version number (in-chain time) corresponding to each business data.

In one of the embodiments, the server searches for the business data corresponding to the business data identifier from the blockchain according to the business data query request and the review status is approved, and selects the latest version number from the business data found (or The business data with the latest chain entry time) is used as the target business data.

In one of the embodiments, step S212 includes: searching for pre-stored business data from the blockchain according to the business data identifier; filtering out the business data whose audit status is approved from the searched business data; Select the latest version of the business data from the data as the target business data.

Specifically, the server determines the service data identifier according to the service data query request, and according to the service data identifier, searches the blockchain for multiple pieces of pre-stored service data corresponding to the service data identifier. The server respectively determines the review status of the multiple pieces of business data, and filters out one or more pieces of business data whose review status is approved by the multiple pieces of business data. When multiple pieces of business data are filtered out, the server selects the latest version of the business data from the multiple pieces of filtered business data as the found target business data. When a piece of business data is filtered out, the server uses this piece of business data as the target business data.

In one of the embodiments, the server separately determines the in-chain time of each service data that is filtered out, and compares the in-chain time to select the business with the latest or latest in-chain time from the filtered service data according to the comparison result Data as the target business data. Therefore, the target business data is the business data whose audit status is approved and entered the chain (written to the blockchain) at the latest or most recently.

In one of the embodiments, the server will prioritize each service data queried from the blockchain according to the service data identifier and according to the version number (or link time) to obtain the service data sequence (or service data list). The server prioritizes the business data according to the reverse order of version number (or descending order of entry time). The sorting method of the version number in reverse order means that the business data with the latest version number is ranked first, and so on. The descending order of entry time means that the business data corresponding to the latest or most recent entry time is ranked first, and then sorted downward. Therefore, the business data with the latest version number (latest or latest entry time) It has the highest priority in the business data sequence.

Further, the server filters out the business data whose review status is approved and has the highest priority from the business data sequence, as the target business data. The server sequentially judges the review status of each business data in the order of priority from high to low. When the review status of the business data is determined to be approved, the business data is determined as the target business data and the judgment operation is stopped. When it is determined that the review status of the business data is not passed, for each business data whose review status has not been determined, the server returns to the step of determining the review status of each business data in the order of priority from high to low and continues to execute until it is determined The review status of the business data is approved, or when the judgment operation performed sequentially for each business data in the business data sequence is completed, the iteration is stopped.

In the above-mentioned embodiment, the business data whose audit status is approved is initially selected from the business data found, and the latest version of the business data is selected as the target business data from the initially filtered business data to ensure the found target business Data is business data modified by one party and approved by the other party, so as to ensure the consistency of business data and the accuracy of business data processing.

In one of the embodiments, selecting the latest version of the business data from the filtered business data as the target business data includes: extracting the timestamp from the version number of the filtered business data; selecting from the filtered business data The latest business data with the extracted timestamp is used as the target business data.

The version number is the identification number of the version, and is used to identify the version of the business data corresponding to the business data identifier. The version number includes a timestamp and can also include a random number and/or business data identification. The timestamp can be used to uniquely identify a specific time or point in time, such as the entry time of business data.

Specifically, the server separately determines the version number of each service data that is filtered out, and extracts the timestamp in each version number. The server compares the extracted time stamps to filter out the latest version number of the time stamp from each version number, and uses the business data corresponding to the filtered version number as the target business data.

In one of the embodiments, when the business data corresponding to the business data identifier is found from the blockchain, the server separately determines the review status and version number of each business data, and extracts the timestamp in each version number so as to be based on the timestamp Determine the entry time of each business data. The server obtains the current system time and the pre-configured preset duration, uses the current system time as the end time of the time period, and uses the preset duration as the time period duration, determines the start time of the time period according to the current system time and the preset duration, and then The time period start time and the time period end time determine the time period. The server compares the in-chain time of each business data with the time period to filter one or more business data whose in-chain time belongs to the time period and whose audit status is approved. When a piece of business data is filtered out, the filtered business data is determined as the target business data; when multiple business data are filtered out, the business data with the latest chaining time is selected from the multiple business data filtered out, As the target business data; when the business data is not filtered out, a prompt message indicating that the business data query fails is fed back to the first terminal.

In one of the embodiments, when receiving a business data query request corresponding to a business data identifier sent by another computer device, the server uses the business data search method provided in one or more of the above embodiments to retrieve data from the blockchain. Find the corresponding target business data. Other computer equipment such as the second terminal or the third terminal.

When receiving the service data modification request sent by the first terminal, the corresponding determined modified service data is stored in the blockchain, and the service data review instruction is pushed to the second terminal, and the second terminal is then directed to the modified The review opinion data fed back by the business data is used as the review status, and is stored in the blockchain in association with the modified business data. Therefore, based on the non-tampering modification of the blockchain, the traceability and authenticity of business data modification and review opinion data can be guaranteed, so as to ensure the processing accuracy of business data. Further, when the business data query request sent by the first terminal corresponding to the business data identifier is received, and the review status of the corresponding modified business data is the review failed, the latest version is searched in the blockchain according to the business data identifier , And the audit status is the target business data that has passed the audit. In this way, when the review status of the latest version of the business data corresponding to the business data identifier is the review failed, the latest version of the business data is selected as the target business data from the business data whose review status is the approved business data to achieve the rollback of the business data , Can ensure the consistency of the business data accessed by multiple business parties, thereby further improving the processing accuracy of the business data.

In one of the embodiments, after step S208, the foregoing business data rollback method further includes: when the review opinion data is that the review failed, determining the modifier account corresponding to the modified business data, and generating a notification indicating that the review failed Information; the notification information is sent to the third terminal logged in with the modifier account.

The modifier account is an account pre-registered by the modifier and used to log in to the third terminal. The modifier can log in to the third terminal based on the modifier account, or log in to a specific client, browser, webpage or system with the third terminal, and then query and modify the target service data with the third terminal.

Specifically, when the review opinion data fed back by the second terminal for the modified business data is that the review failed, the server determines the modifier account based on the modified business data, and generates notification information indicating that the review failed based on the review opinion data, And send the notification information to the third terminal logged in with the modifier account. The third terminal displays the received notification information to the modifier through the modifier operation interface. The server can extract the modifier's account from the modified business data, or find the modifier's account from the blockchain based on the modified business data. It can be understood that the third terminal may be the first terminal, which is specifically determined according to the modifier account.

In one of the embodiments, the server determines the modifier ID based on the modified business data, queries the pre-configured modifier account based on the modifier ID, or determines the third terminal ID based on the modifier ID, and then based on the modifier account or third The terminal identifier determines the third terminal that receives the notification information.

In one of the embodiments, when the review opinion data indicates that the review is passed, the server generates notification information identifying that the review is passed, and sends the notification information to the third terminal determined in the foregoing manner.

In the above embodiment, when the received review opinion data is that the review has not passed, the generation of notification information indicating that the review has not passed is triggered and fed back to the third terminal for display, so that the modifier can perform follow-up operations based on the review results, such as initiating again Modify operations to ensure the consistency and accuracy of business data.

In one of the embodiments, the foregoing service data rollback method further includes: receiving a modified data query request corresponding to the service data identifier sent by the first terminal; and searching the history corresponding to the service data identifier from the blockchain according to the modified data query request Modify data; send historical modified data to the first terminal.

The modified data query request is a request used to trigger a modified data query operation, and is used to instruct the server to find and feed back the historical modified data corresponding to the service data identifier. Historical modification data refers to modified business data obtained by modifying the business data corresponding to the business data identifier before the current system time.

Specifically, the server receives the modified data query request sent by the first terminal, parses the modified data query request to obtain the service data identifier, and searches the blockchain for historical modification data corresponding to the service data identifier according to the service data identifier, and then queries The received historical modification data is sent to the first terminal.

In one of the embodiments, the server searches for the business data corresponding to the business data identification in the blockchain according to the business data identification, and determines the version number of each business data (in-chain time) according to each version number (in-chain time) from The historical modification data is filtered out from the business data found. The server determines the business data after excluding the business data with the earliest version number (or the earliest access time) from the found business data as historical modification data. It is understandable that the second terminal can also use the server to search for historical modification data corresponding to the service data identifier from the blockchain in the foregoing manner. In one of the embodiments, the server may determine the business data with the earliest version number (or the earliest link time) corresponding to the business data identifier, that is, the initially created business data as historical modification data.

In the foregoing embodiment, by searching and feeding back historical modification data, it is possible to quickly and intuitively understand the business data of each version corresponding to the business data identifier.
