Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart illustrating a block chain-based file data processing method according to an embodiment of the present invention, where the embodiment is applicable to a case of processing file data, and the method can be executed by a block chain-based file data processing apparatus at a user node. As shown in fig. 1, the method specifically includes the following steps:
and step 110, after determining that the initial version of the target file is stored in the block chain, acquiring operation data of the target file by a user.
Before a user operates the initial version of the target file for the first time, the user node needs to determine whether the initial version of the target file is stored in the block chain.
Optionally, an initial on-link query request of the target file is sent to the blockchain network; the initial on-chain query request is used for indicating the block chain network to determine whether an initial version of the target file is stored in the block chain.
Specifically, the user node may send an initial on-chain query request of the target file to the blockchain network, and the blockchain network may receive the initial on-chain query request and may search whether the initial version of the target file exists on the blockchain. If the initial version of the target file already exists, the initial version of the target file can be opened, and the target file is operated. After determining that the initial version of the target file is stored in the block chain, the user node can directly open the target file from the block chain when operating the target file later, so that the user operation is facilitated.
Optionally, if the initial version of the target file is not stored in the block chain, an initial uplink request including the initial version of the target file is sent to the block chain network, where the initial uplink request is used to instruct the block chain network to write the initial version of the target file into the block chain.
Specifically, if the initial version of the target file does not exist in the blockchain, the user node may send an initial uplink request including the initial version of the target file to the blockchain network, and store the initial version of the target file in the blockchain, so that the user can directly open the target file from the blockchain when next operating the target file.
After the target file is opened by a user, the target file is operated, and the user node acquires operation data of the user, wherein the user node can be computer equipment such as a computer, and the operation data comprises at least one item of operation type, operation position and operation text and identification information of the target file. The operation type may be an operation action of the user, such as an operation of adding, deleting, font bolding, and inserting. The operation location may be a location where a user operates on the target file, such as the first segment, first line, or more specifically, the first few words of the target file. The operation content may be an object when the user performs an operation action on the target file, for example, a word "good" is added, or two words "introduction" are bolded, and the "good" and "introduction" are the operation content. The identification information of the target file may be an identification of the target file so as to record the target file targeted by the user operation.
After the user operates the target file, the user node can store the operation data on the chain, so that when the target file is opened later, the user node can check a new version. The user node may send an update request for the on-chain file including the operation data to the blockchain network, and the blockchain network receives the update request for the on-chain file and writes the operation data in the request into the blockchain, that is, the initial version and the operation data of the target file are stored in the blockchain. When the blockchain network stores the operation data, the time stamp can be used as the identifier to record the storage time of the operation data, so that the target files of different versions can be distinguished conveniently, and the changed content of the files is associated with the blockchain information in real time. The function that the block chain technology can not be tampered is utilized, and the operation data is prevented from being damaged.
According to the technical scheme of the embodiment, the target file in the block chain is opened, the target file is operated, the operation data of the user is obtained, and the operation data is stored in the block chain. The updated content of the file is stored by using the blockchain technology, the credibility and the reliability of the updated content of the file can be improved according to the function of the blockchain technology, which cannot be tampered, the loss of operation data is avoided, and the checking of target files of different versions is supported.
Example two
Fig. 2 is a flowchart illustrating a block chain-based file data processing method according to a second embodiment of the present invention, and the present embodiment is further optimized based on the above embodiments, and the method can be executed by a block chain-based file data processing apparatus at a user node. As shown in fig. 2, the method specifically includes the following steps:
When a user operates the initial version of the target file for the first time, the user node needs to judge whether the initial version of the target file is stored in the block chain. The first operation by the user is for the initial version of the target file and the subsequent operation is for the version of the target file of the previous operation.
Specifically, after the user operates the initial version of the target file for the first time, the user can directly open the version after any previous operation when the user operates or views the target file later. The method comprises the steps that a user node sends a link query request of a target file to a blockchain network, operation data of the target file within preset time can be searched according to a timestamp on the blockchain, the blockchain network obtains an initial version and the operation data of the target file from the blockchain, the operation data within the preset time are edited into the initial version of the target file according to the query request of the user node on the target file, and a new version of the target file is generated. By utilizing the source tracing function of the block chain, a user can select a target file version at a certain time node, for example, the user operates an initial version of a target file in 11 month and 1 day in 2019, operates the version in 11 month and 1 day in 11 month and 2 days in 2019, and selects the time node in 11 month and 2 days to view the latest target file version if the user wants to view the target file of the latest version. By utilizing the property that the block chain can not be tampered, the operation data written into the block chain can not be changed randomly, and the target file is prevented from being damaged.
The method and the device for generating the new version of the target file have the advantages that the operation data of the target file by the user are obtained, the operation data of the user are stored in the block chain, and the operation data of the required version and the initial version of the target file are obtained when the new version of the target file is opened again, so that the new version of the target file is generated. The system management of the target files of different versions is realized, the target files of new versions are generated according to the needs of users, the confusion of files and the loss of operation data are avoided, and the checking of the target files of different versions is supported.
EXAMPLE III
Fig. 3 is a flowchart illustrating a method for processing block-chain-based file data according to a third embodiment of the present invention, where the method is applicable to processing file data and can be executed by a block-chain-based file data processing apparatus of a block-chain network node. As shown in fig. 3, the method specifically includes the following steps:
Optionally, receiving an initial on-chain query request of the target file; the initial on-chain query request is used for indicating the block chain network to determine whether an initial version of the target file is stored in the block chain.
Specifically, the block chain network receives an initial on-chain query request sent by a user node, queries whether an initial version of the target file is stored in the block chain, and if the initial version of the target file exists in the block chain, may open the initial version of the target file for operation.
Optionally, if the initial version of the target file is not stored in the block chain, an initial uplink request including the initial version of the target file is received, where the initial uplink request is used to instruct the block chain network to write the initial version of the target file into the block chain.
Specifically, if the initial version of the target file does not exist in the block chain, the block chain network receives an initial uplink request of a user node for the initial version of the target file, and stores the initial version of the target file in the block chain, so that the block chain can directly open the target file from the block chain when receiving the operation request of the target file again later.
After determining that the initial version of the target file is stored in the blockchain, the blockchain network receives an on-chain file updating request sent by a user node, wherein the on-chain file updating request comprises operation data of the user on the target file. The block chain network acquires operation data of a user on the target file, wherein the operation data comprises at least one item of operation type, operation position and operation text and identification information of the target file. And aiming at the operation data of the user on the target file, the block chain network generates an on-chain file updating request comprising the operation data so as to update the initial version of the target file on the block chain.
And step 320, writing the operation data into the block chain.
The block chain network receives a file update request on a chain sent by a user node, and stores operation data in the file update request on the chain into a block chain, namely the block chain stores an initial version and operation data of a target file. The operation data can be saved by taking the timestamp as the identifier, so that the block chain can search the operation data of the corresponding version according to the timestamp when the target file of the new version is opened. The operation data written in the block chain can utilize the property that the block chain can not be tampered to avoid the operation data from being damaged.
Optionally, the method further includes: when the target file is locally reopened, the block chain network receives an on-chain query request of the target file, wherein the on-chain query request is used for indicating the block chain network to acquire an initial version and operation data of the target file from the block chain; and generating the latest version of the target file according to the initial version and the operation data of the target file.
If the target file is to be reopened, the user node sends an on-chain query request of the target file, the block chain network receives the on-chain query request, and the operation data of the corresponding time node and the initial version of the target file are searched according to the user requirement. For example, the initial version of the target file is stored in the blockchain, the initial version of the target file is changed once, and when the target file of the new version is viewed, the initial version of the target file and operation data performed during the change are opened to generate the target file of the latest version.
According to the embodiment of the invention, the operation data of the target file is stored in the block chain by receiving the on-chain file updating request which is sent by the user node and comprises the operation data, so that the change content of the target file is associated with the block chain, the condition that the target file is lost integrally is avoided, the user can conveniently check the target files of different versions, the credibility and the reliability of the updating content of the file are improved according to the non-falsification function of the block chain technology, the loss of the operation data is also avoided, and the checking of the target files of different versions is supported.
Example four
Fig. 4 is a flowchart illustrating a block chain-based file data processing method according to a fourth embodiment of the present invention, and the present embodiment is further optimized based on the third embodiment. As shown in fig. 4, the method specifically includes the following steps:
The unacknowledged on-chain file update request refers to an on-chain file update request stored in an unacknowledged block of the block chain. The unacknowledged block may be the current block or a predetermined number of blocks before the current block.
After receiving an on-chain file update request including operation data sent by a user node, the blockchain network needs to write the operation data into a blockchain. Before writing the operation data into the blockchain, a conflict intelligence contract may be invoked to determine whether the operation data in the on-chain file update request conflicts with the operation data in the unconfirmed on-chain file update request stored in the blockchain.
The conflict intelligent contract judges whether the operation data of the file updating request on the unconfirmed chain conflicts with the operation data of the file updating request on the current chain in the following mode: if the operating data of the file updating request on the link is not confirmed to be completely consistent with the operating type, the operating position, the operating text and the identification information of the target file in the operating data of the file updating request on the link, the conflict exists; otherwise, it indicates that no conflict exists. For example, if it is not determined that the operation data of the on-chain file update request is to change the first word in the first row of the target file to "pair", and the operation data of the current on-chain file update request is to change the first word in the first row of the target file to "error", it indicates that a conflict occurs. If the conflict between the operation data of the on-chain file updating request and the operation data of the on-chain file updating request is not confirmed, the target file is refused to be changed at least twice; if no conflict is generated, the operation data is written into the block chain and takes effect after a preset time range or after a preset number of blocks are met.
The embodiment of the invention determines whether the update request of the files on the chain conflicts with other update requests of the files on the unconfirmed chain by receiving the update request of the files on the chain which comprises the operation data and is sent by the user node. And if the conflict exists, rejecting all the conflicting on-chain file updating requests, and if the conflict does not exist, writing the operation data in the on-chain file updating requests into the block chain. By utilizing the characteristics of rollback and source tracing of the block chain technology, the updated content of the file is stored, the credibility and the reliability of the updated content of the file are improved, the situations of loss and error modification of operation data are avoided, and the checking of target files of different versions is supported.
