The technical solution provided by the present invention is suitable for data storage scenarios under the blockchain architecture. For example, there is a certain group company, the group company includes one head office, each head office corresponds to multiple first-level subsidiaries, and each one Level 2 subsidiaries correspond to multiple Level 2 subsidiaries. At this time, the head office has the highest financial data query authority. The head office can query the financial data of any level 1 subsidiary and any level 2 subsidiary. Subsidiaries, Level 2 subsidiaries are only able to view their own financial data. In the prior art solution, each node will store its own financial data. When a tier-1 subsidiary needs to view the financial data of a tier-2 subsidiary, it needs to send a data query request to the tier-1 subsidiary. The identity of the subsidiary is authenticated, and the corresponding financial data is retrieved according to the authentication result. When the identity of the first-level subsidiary is authenticated, it is necessary to traverse the corresponding permissions of all the second-level subsidiaries, which makes the search process of financial data efficient. lower. The technical scheme of the present invention can solve the problem of low search efficiency of financial data under the block chain structure.

The present invention provides a blockchain-based financial data storage method, as shown in Figure 1, including:

Step S110: Receive the first financial data uploaded by the first node in the blockchain, and determine the multi-dimensional storage data information corresponding to the first node according to the first role corresponding to the first node. The present invention takes the node that uploads the first financial data as the first node. A node in the blockchain will upload the first financial data at a certain time, and the first financial data can be tax returns, income statements, balance sheets, and so on. Each node in the blockchain will have its corresponding role, and the present invention will use the role corresponding to the node that uploads the first financial data as the first role. The present invention can determine the multi-dimensional storage data information corresponding to the first node according to the first role corresponding to the first node.

In a possible implementation manner of the technical solution provided by the present invention, as shown in FIG. 2 , step S110 specifically includes:

Step S1101: Acquire a first role corresponding to a first node, and determine a corresponding first set in the correspondence table according to the first role, where the first set includes at least one second role. Since each node will have a corresponding role, when uploading financial data to a certain node, the present invention will use the node uploading financial data as the first node, and the role corresponding to the first node will be the first role. The first role determines the corresponding first set in the correspondence table, and stores all the second roles through the first set. This method enables the present invention to store the corresponding relationship between the first role and multiple second roles.

Step S1102: Acquire all storage spaces corresponding to all second roles in the first set to generate multi-dimensional storage data information, wherein each second role corresponds to one storage space. The present invention will generate multi-dimensional storage data information according to all the storage spaces corresponding to all the second roles, and according to the multi-dimensional storage data information, the financial data uploaded by the first role can be uniformly distributed, and the uploaded financial data can be distributed to those with corresponding authority. in the storage space corresponding to the second role. This method enables active distribution of financial data, so that each node distributes its own financial data according to the first set to other nodes that have the ability to view the financial data of the node.

The technical solution provided by the present invention generates a corresponding table through the following steps, including:

The node configuration data input by the user is processed to generate the connection relationship information and role level information of each node in the blockchain. When the corresponding table is initially generated, administrators and users will input node configuration data. At this time, the node configuration data will have the connection relationship information and role level information of each node. For example, if there are company 1, company 2, company 3, company 4 and company 5, the connection relationship information can be that company 1 is connected with company 2 and company 3, and the role level information of company 1 is the head office, company 2 and company 3. The role level information is a level 1 subsidiary, the connection relationship corresponding to company 4 is connected to company 2, company 4 is a level 2 subsidiary, the connection relationship corresponding to company 5 is a connection with company 3, and company 5 is a level 2 subsidiary .

The present invention generates a first set corresponding to each node according to the root node, multiple child nodes and multiple grandchild nodes, for example. The grandchild node corresponding to the second-level subsidiary (company 4) is connected to the child node corresponding to the first-level subsidiary (company 2), and the child node corresponding to the first-level subsidiary (company 2) is connected to the parent company (company 1). Corresponding root node connection. At this time, the head office (company 1) can view both the financial data of the first-level subsidiary (company 2) and the financial data of the second-level subsidiary (company 4). At this time, the first set corresponding to the root node is It includes at least the role of the node corresponding to the first-level subsidiary (company 2) and the role of the node corresponding to the second-level subsidiary (company 4). At this time, the node corresponding to the first-level subsidiary (company 2) and the node corresponding to the second-level subsidiary (company 4) will send the financial data to the storage corresponding to the root node (company 1) when uploading the financial data. storage in space.

In the actual production and operation activities, there will also be a situation in which a group company is acquired. At this time, the previous root node (company 1) no longer has the highest authority, and the upper part of the root node (company 1) may have the highest authority. There is a new node (company 01), then the first set will include itself and the new node (company 01). When the root node (company 1) belongs to the highest authority, only the head office (company 1) of the entire group company can view its own financial data. At this time, the first set corresponding to the root node only has its own financial data. For the corresponding role, the present invention will correspond the first role of the root node to the first set. That is, when the root node uploads financial data, it only needs to store the financial data in the storage space corresponding to its own role in the first set, and other nodes cannot view the financial data uploaded by the root node.

According to the technical solution provided by the present invention, in a possible implementation manner, a first set corresponding to each node is generated according to the root node, multiple child nodes and multiple grandchild nodes, and based on the first set corresponding to each node The generated correspondence table includes:

Obtain the root node corresponding to the level above the child node to generate the first set, and use the role corresponding to the node in the first set as the second role. Generally speaking, the root node of the financial data of child nodes has permission to view, so the nodes in the first set at least include the root node and the child node itself. At this time, the roles corresponding to the root node and the child node themselves are: The second role in the first set, that is, when the child node uploads financial data, it will upload the financial data to the storage space corresponding to the second role in the first set, that is, the storage space corresponding to the root node, in its corresponding storage space.

Extracting the first role of the child node corresponds to the first set. The present invention will correspond the first role of the child node to the first set, and at this time, the corresponding child node has the first set corresponding to itself.

Obtain the child nodes and root nodes corresponding to the next level of the grandchild node to generate a first set, and use the roles corresponding to the nodes in the first set as the second role. Generally speaking, the financial data of the grandchild node, the corresponding child nodes and the root node are all authorized to view, so the nodes in the first set at least include the corresponding child nodes, the root node and the grandchild node itself. At this time, the corresponding The roles corresponding to the child node, the root node, and the grandchild node themselves are the second roles in the first set, that is, when the grandchild node uploads financial data, it will upload the financial data to the second role in the first set. In the storage space, that is, the storage space corresponding to the corresponding child node, the storage space corresponding to the root node, and the storage space corresponding to itself.

The first role of the extracted grandchild node corresponds to the first set. The present invention will correspond the first role of the grandchild node to the first set, and at this time, the corresponding grandchild node has the first set corresponding to itself.

In the present invention, multiple storage units will be set in each storage space in advance. For example, if the child node (company 2) can view the financial data of the grandchild node (company 4) and its own, the corresponding storage unit at this time can be It includes a storage unit 1 and a storage unit 2. The storage unit 1 can store the financial data of the child node (company 2), and the storage unit 2 can store the financial data of the grandchild node (company 4). For example, when the grandchild node (company 4) uploads financial data, the role corresponding to the grandchild node (company 4) is the first role, and the first financial data will be stored in the child node (company 2). In the storage unit corresponding to the first role (company 4) in the corresponding storage space.

Extracting all the second financial data previously stored in the storage unit corresponding to the role of the first node and the time stamp corresponding to the second financial data. After determining the corresponding storage unit in the storage space, the present invention extracts all the second financial data previously stored in the storage unit corresponding to the role of the first node and the time stamp corresponding to the second financial data. For example, if there are two second financial data, including the annual tax return for 2019 and the annual tax return for 2020, the time stamps corresponding to the annual tax return for 2019 are 2019 and 2020. The time stamp corresponding to the annual tax return for 2020 is the year 2020.

The second financial data and the first financial data are sorted based on the time stamp of the second financial data and the time stamp of the first financial data to obtain third financial data sorted in time series. For example, if the time stamp of the first financial data is 2021, the third financial data sorted by time series at this time are the financial data of 2019, the financial data of 2020, and the financial data of 2021. In this way, the financial data is saved, so that the financial has a corresponding time series, and it is easy to retrieve statistics and financial data.

Step S140: If it is determined that all the storage spaces corresponding to the multi-dimensional storage data information are respectively updated to obtain the third financial data, remind all nodes corresponding to the second role and the first role to complete the storage. The technical solution provided by the present invention will remind the nodes corresponding to the second role and the first role after all the storage spaces corresponding to the multi-dimensional storage data information are respectively updated to obtain the third financial data, so that the present invention uploads the financial data on a certain node. After the data, corresponding reminders can be made, so that each node with the authority to view the financial data can check and view the corresponding financial data in time.

Compared with the traditional way of actively checking the financial data of a subsidiary company, the technical solution provided by the present invention adopts a passive upload reminder method, that is, as long as a certain node uploads the corresponding financial data, the financial data will be updated. Active distribution is carried out according to role permissions, so that all nodes passively receive financial data, and check and verify financial data.

The technical solution provided by the present invention also includes:

Count the roles corresponding to all nodes, and obtain the number of each role in the first set corresponding to all nodes. The technical solution provided by the present invention will count the number of roles of each node in all the first sets. When the number is larger, it is proved that the more nodes that store financial data to it, the more financial data it receives. The more, the greater the amount of storage space required.

The amount of preallocated storage space corresponding to the corresponding node is determined based on the number of each role in all of the first sets. When the present invention performs the initial allocation of the storage quantity value to each storage space, it will be determined according to the quantity in all the first sets, so that each storage space has a suitable storage quantity value, and the allocation of the storage quantity value this time is only It is to consider the quantity dimension of each role in all the first sets, and does not consider the data volume dimension of the financial data of each node, because the operating status of each company cannot be determined at this time, so the amount of its financial data is not yet available. Sure.

The amount of preallocated storage space is calculated by the following formula,

The proportion of the number of roles in all the first sets to the total number value, and then the total storage value is allocated according to the corresponding proportion. The node type weight value can be preset, and the node type weight value of the root node can be greater than the child type weight value. The node type weight value of the node. The node type weight value of the child node can be greater than the node type weight value of the grandchild node. The role weight value can be preset by the user and determined according to the attributes of each node and role. For example, if the subsidiary is a traditional industry and there are few in and out items, the financial data may be less, then the role weight value may be If it is relatively low, for example, if the subsidiary is an emerging industry such as new energy, and there are many in and out items, there may be more financial data, and the role weight value may be higher at this time.

The total storage space is initially allocated based on the magnitude of the pre-allocated storage space, so as to allocate a corresponding initial storage space to each node. The present invention will initialize and allocate each storage space according to the allocated storage value of each storage space, so that each node has a corresponding storage space.

The technical solution provided by the present invention also includes:

Obtain the value of the data stored at the current moment in each storage space at preset time intervals. In the actual production and operation activities of the company, due to the different types and operating conditions of the company, the input and output items of the company corresponding to each node may be quite different, and the value of the financial data generated at this time will be There is a large deviation, so the financial data sent by each node to other nodes will also be different. The present invention obtains the data stored quantity value at the current moment in each storage space at preset time intervals, and dynamically adjusts the quantity of the redistributed storage space according to the stored quantity value of each storage space.

Obtain the current average stored volume value according to the stored volume value of data in each storage space.

The allocated storage amount value of the storage space is adjusted according to the data stored amount value in each storage space, the current stored average amount value, and the role weight value corresponding to each storage space. The present invention will adjust the allocated storage value of the storage space according to the stored data value, the current stored average value, and the role weight value corresponding to each storage space, so that the re-allocated storage value of each storage space can be adjusted. There is a corresponding relationship with its current stored value, so as to achieve a reasonable allocation of storage value, allocate more storage space to more needed nodes, and ensure the stable storage of financial data.

According to the technical solution provided by the present invention, the allocated storage capacity value of the storage space is adjusted according to the stored value of the data in each storage space, the current stored average value and the role weight value corresponding to each storage space include:

If it is judged that the stored quantity value of the data is greater than or equal to the current stored average quantity value. At this time, the trend of the data increase of the storage space of the corresponding node is greater than the trend of the data increase of the storage space of other nodes, so it needs more storage space to meet the data storage requirement.

A positive change trend value is obtained based on the stored data volume value and the stored average volume value, and a positive adjustment is performed on the allocated storage volume value in the storage space based on the first positive change trend value and the role weight value. The present invention will obtain the positive change trend value according to the stored value of the data and the stored average value. When the stored value of the data is greater than the stored average value, the larger the positive change trend value, the greater the positive change trend value. The larger the adjustment, the more storage space is allocated.

If it is judged that the stored quantity value of the data is less than the current stored average quantity value. At this time, the trend of the data increase of the storage space of the corresponding node is smaller than the trend of the data increase of the storage space of other nodes, so it needs less storage space to meet the data storage requirement.

The negative change trend value is obtained based on the stored data volume value and the stored average volume value, and the allocated storage volume value in the storage space is negatively adjusted based on the negative change trend value and the role weight value. The present invention will obtain the negative change trend value according to the stored volume value and the stored average volume value of the data. When the stored volume value of the data is smaller than the stored average volume value, the larger the negative change trend value, the greater the negative change trend value. The larger the adjustment, the less storage space is allocated.

Through the above methods, the present invention can realize the dynamic and on-demand allocation of the storage capacity value of the storage space, and ensure that the storage capacity value of the storage space corresponding to each node corresponds to its storage requirement.
