DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] In Example 1, Figure 1 The implementation process of the digital archive management method based on blockchain provided by an embodiment of the present invention is shown and described in detail below: S100: Acquire digital files, determine the number of each digital file using a preset numbering rule, configure the storage node of the digital file, construct a hash function corresponding to the storage node, hash the number, and obtain a hash value.

[0019] The digital archives are numbered using a numbering rule, wherein the numbering rule can be based on time or content, and the number of each digital archive is determined; storage nodes that can be used to store digital archives are determined, and a hash function is determined for each storage node, wherein the hash function can be selected from existing data, and the number is hashed using the hash function to determine the hash value.

[0020] In the process of digital file management, the required digital files can be quickly located by using hash values, and any changes to digital files (such as addition, modification or deletion) will also recalculate the hash value; in other words, by comparing hash values, changes in digital files can be monitored.

[0021] By hashing the numbers, the storage and backtracking process of the archives can be optimized to ensure that the data cannot be tampered with and is traceable. By building blocks, the relationship between storage nodes can be established, storage efficiency can be optimized, and management costs can be greatly reduced.

[0022] S200: Create a block, establish a mapping between the block and the storage node, configure the corresponding relationship between the number, block and storage node, synchronize the hash value to the corresponding block, integrate all blocks, and build a blockchain.

[0023] Create blocks that correspond to storage nodes one by one, transfer hash values ​​to corresponding blocks, integrate all blocks, and generate a blockchain, in which each block contains not only the hash value of the digital file number but also the hash value of the previous block.

[0024] For example, there is a blockchain composed of three blocks A, B and C, where A stores digital files numbered A and B, B stores digital files numbered C, and C stores digital files numbered D; A and B are integrated and hashed to obtain a first hash value, which is stored in B, the first hash value and C are integrated to generate a second hash value, which is stored in C, and so on. All blocks are linked to build a hash chain. The advantage of this is that it can prevent digital files from being tampered with and quickly trace the required digital files.

[0025] By building a blockchain, we can eliminate the reliance on a single centralized storage method in the digital archive management process, achieve decentralization, and improve the fairness and reliability of digital archive management. By generating transaction forms and additional blocks, incremental data can be linked to the blockchain, thereby preventing digital archives from being tampered with and forged, greatly reducing the amount of data processing and improving the management efficiency of digital archives.

[0026] S300: Build a communication link between all storage nodes and the blockchain, create a root node, and embed a tilt mechanism, mount the communication link to the root node, receive write requests uploaded by users, and upload them to the root node, generate a transaction form, wherein the transaction form includes at least: change nodes, incremental data and write time.

[0027] After receiving a write request, the communication link is triggered to start and a new block is inserted into the blockchain synchronously; a root node is created and a tilt mechanism is embedded in the root node. When a write request is received, the root node will tilt; when the user needs to modify, create or delete file data, the digital file that needs to be changed is selected and defined as the original data. When the writing is completed, the modified data is determined, the original data and the modified data are compared, the incremental data is determined, and a transaction form is generated, where the transaction form includes the node where the original data is located (the changed node), the incremental data and the writing time, etc.

[0028] It should be noted that after the data is written, the original data will not be modified, but the incremental data will be stored.

[0029] S400: Select an idle node from the storage node and write it into the transaction form; based on the corresponding relationship, define the block corresponding to the change node as the target block; integrate the incremental data and the hash value in the target block to generate a comprehensive value; use the hash function corresponding to the change node to hash the comprehensive value to obtain an additional value; insert an additional block into the target block, and synchronize the additional value to the additional block.

[0030] When data needs to be written, an idle node is selected from the storage node and the transaction form is stored. In order to establish the relationship between the original data and the incremental data, the hash value in the block corresponding to the original data is integrated with the incremental data, and the hash is continued to generate a new hash value, that is, the additional value, and the target block is used to store the additional value. It can be seen that by using the target block to store the additional value, the original data and the corresponding incremental data can be traced back, and after integration, the modified digital file can be determined.

[0031] In this embodiment, when the data in the storage node is called, the data therein will not change, but incremental data will be generated after the call. The incremental data will be stored in the idle node, and an additional block will be inserted into the block corresponding to the storage node to record the incremental data, wherein the additional value is mainly used to establish the relationship between the original data and the incremental data.

[0032] In Example 2, Figure 2 The implementation process of the digital archive management method based on blockchain provided by an embodiment of the present invention is shown, and S100 is described in detail below, as follows: S101: Integrate the serial numbers and hash values ​​of all digital archives, generate a query directory, and integrate the query directory into the root node.

[0033] Integrate the numbers of all digital files and their corresponding hash values ​​to generate a query directory, where the query directory serves as an index file that shows the correspondence between the digital file numbers and the hash values. When the digital file is modified, the corresponding hash value will also change accordingly. In this process, since the hash value is stored in the block, the modification of the digital file can be monitored by managing the block.

[0034] S102: Generate additional items using the hash function, and write the additional items into the query directory.

[0035] Each storage node corresponds to a hash function. Using this correspondence, additional items are generated and integrated into the query directory to quickly determine the storage location of the digital archive.

[0036] In Example 3, Figure 3 The implementation process of the digital archive management method based on blockchain provided by an embodiment of the present invention is shown, and S200 is described in detail below, as follows: S201: Traverse the attribute data of the storage node, wherein the attribute data at least includes: available capacity and hardware configuration.

[0037] The attribute data of each storage node is determined, wherein the attribute data includes: available capacity and hardware information of the storage node.

[0038] S202: Migrate the attribute data to the root node, embed a monitoring strategy, and dynamically update the attribute data using the monitoring strategy.

[0039] The root node is used to coordinate the management of all storage nodes. The monitoring strategy is a specific monitoring method for storage nodes, such as reading the logs of storage devices and using monitoring tools. The attribute data is dynamically updated based on the monitoring results.

[0040] In Example 4, Figure 4 The implementation process of the digital archive management method based on blockchain provided by an embodiment of the present invention is shown, and S300 is described in detail below, as follows: S301: activating the monitoring strategy, and tilting the root node when the root node detects a write request.

[0041] When the monitoring strategy detects a write request, it tilts the root node; the purpose of tilting the root node is to intuitively display the number of write requests for digital archives in the root node.

[0042] S302: query a preset comparison table to determine the tilt angle of the root node, wherein the comparison table at least includes: write quantity and tilt angle items, and modify the root node.

[0043] The number of write requests in the root node is counted, and the comparison table is queried to determine the tilt angle of the root node, wherein the comparison table includes: write request items and tilt angle items. The root node is corrected according to the tilt angle. The above-mentioned write request item is the number of write requests.

[0044] In Example 5, Figure 4 The implementation process of the digital archive management method based on blockchain provided by an embodiment of the present invention is shown, and S300 is further described in detail as follows: S303: Determine the transmission load of the incremental data, and separate a backup link from the communication link.

[0045] Based on the size of the incremental data, transmission frequency and time requirements, calculate the bandwidth and resource occupancy rate required to transmit the incremental data, evaluate the load of the current communication link, and when the communication link is close to the load limit, rebuild a backup link and use the backup link to balance the load.

[0046] S304: Reconstruct the transmission load using the backup link.

[0047] By utilizing the backup link, the transmission load is adjusted to make the load more balanced and ensure the normal transmission of data.

[0048] In Example 6, Figure 5 The implementation process of the digital archive management method based on blockchain provided by an embodiment of the present invention is shown, and S400 is further described in detail below, as follows: S401: Link all additional blocks to generate sub-chains, and insert the sub-chains into the blockchain.

[0049] After multiple calls to the digital archives in the storage node, multiple additional blocks are generated. All the additional blocks are linked according to timestamps and logical order to generate sub-chains, where the sub-chains are mainly used to represent version changes of digital archives.

[0050] S402: Establish a version update mechanism to determine the version number of each sub-chain.

[0051] When a subchain changes, the version update mechanism is used to determine the changed subchain as a version, and a version number is determined for each version. The version update mechanism is a specific method of version update, such as updating based on version number changes or updating based on time.

[0052] In Example 7, different from Example 1, in this embodiment of the present invention, the method further includes: Establishing a coordinated relationship between the root node and all storage nodes; The blockchain is sliced ​​to obtain a number of chain slices, and redundant nodes are inserted into each of them to form a redundant architecture.

[0053] The root node is used to coordinate and manage all storage nodes, and the blockchain is divided into several pieces. Each piece is isolated from each other. Redundant nodes are used to back up the data in the pieces. The redundant nodes come from the storage nodes. All redundant nodes are integrated into the redundant architecture to generate a backup network, thereby performing redundant backup of the pieces.
