[0011] In some embodiments of this application, when the file processing operation is to open or refresh the latest block query template file, the step of interacting with the remote blockchain node connected to the virtual drive according to the blockchain file system callback function to obtain blockchain file processing data, in order to execute the file processing of the blockchain file system, includes: obtaining the latest block information of multiple blocks from the remote blockchain node connected to the virtual drive according to the blockchain file system callback function; triggering a file write request; responding to the thread pool of the blockchain file system listening to the file write request, generating a blockchain file write function corresponding to the file write request; and writing the obtained block information into the latest block query template file according to the blockchain file write function.

[0013] In some embodiments of this application, when the file processing operation is to copy and edit the user-created template file, the step of interacting with the remote blockchain node connected to the virtual drive according to the blockchain file system callback function to obtain blockchain file processing data to execute the file processing of the blockchain file system includes: obtaining the user information of the user to be created based on the text information of the edited user-created template file; interacting with the remote blockchain node connected to the virtual drive according to the user information of the user to be created to obtain the serialization information and signature information of the user to be created; sending a transaction to create a new user to the remote blockchain node connected to the virtual drive; triggering a file creation request; responding to the thread pool of the blockchain file system listening to the file creation request, generating a blockchain file creation function corresponding to the file creation request; creating an on-chain authorized user file in the user file directory according to the blockchain file creation function; triggering a file write request; responding to the thread pool of the blockchain file system listening to the file write request, generating a blockchain file write function corresponding to the file write request; and writing the user information to be created into the newly created on-chain authorized user file according to the blockchain file write function.

[0014] In some embodiments of this application, when the file processing operation is to copy and edit the transaction template file, the step of interacting with the remote blockchain node connected to the virtual drive according to the blockchain file system callback function to obtain blockchain file processing data to execute the file processing of the blockchain file system includes: obtaining transaction information based on the text information of the edited transaction template file; sending the transaction information to the remote blockchain node connected to the virtual drive; triggering a file creation request; responding to the thread pool of the blockchain file system listening to the file creation request, generating a blockchain file creation function corresponding to the file creation request; creating a transaction file in the user file directory according to the blockchain file creation function; triggering a file write request; responding to the thread pool of the blockchain file system listening to the file write request, generating a blockchain file write function corresponding to the file write request; and writing the transaction information into the newly created transaction file according to the blockchain file write function.

[0033] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to fully and completely convey the concept of the exemplary embodiments to those skilled in the art.

[0034] The accompanying drawings are merely illustrative of the invention and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software, in one or more hardware forwarding modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0035] Furthermore, the processes shown in the accompanying drawings are merely illustrative and do not necessarily include all steps. For example, some steps can be broken down, some steps can be combined or partially combined, and the actual execution order may change depending on the actual situation. The terms "first," "second," and similar terms used in the specific description do not indicate any order, quantity, or importance, but are only used to distinguish different components. It should be noted that, unless otherwise specified, embodiments of the present invention and features in different embodiments can be combined with each other.

[0036] In practice, the inventors have discovered that existing blockchains are primarily implemented as distributed file systems, emphasizing decentralized operation. However, how to facilitate blockchain operations for users remains a critical technical problem that needs to be solved by those skilled in the art.

[0037] The inventors considered combining file systems with blockchain technology to solve the aforementioned technical problems.

[0038] Blockchain technology is a decentralized distributed data management framework that has been applied to many distributed system scenarios. Through its decentralized and unforgeable computing model, blockchain can efficiently and cost-effectively achieve distributed trusted computing and transactions. Currently, it is widely used in finance, logistics, industrial manufacturing, healthcare, and the Internet of Things.

[0039] Blockchain is decentralized, with each blockchain node operating independently. Meanwhile, smart contracts define the contractual rights to access information, subject to mutual agreement. Smart contracts primarily provide the verification and execution of the conditions stipulated within the contract, allowing for trusted transactions without a third party. These transactions are traceable and irreversible.

[0040] This invention provides a file processing method, apparatus, device, and medium for a blockchain file system. The inventive concept is to use a virtual drive as an entry point, perform file operations on the virtual drive, and then convert these operations into interactions with blockchain nodes through a blockchain file system callback function. By interacting with the blockchain nodes, relevant information is fed back and displayed in the file system, thereby realizing file processing within the blockchain file system. This allows users to perform blockchain processing using familiar file system operation methods.

[0041] Reference Figure 1 The diagram illustrates a flowchart of one embodiment of the file processing method for the blockchain file system provided by the present invention. Figure 1 The following steps are shown:

[0042] Step S110: In response to the user's file processing operation on the virtual drive, generate a file processing request corresponding to the file processing operation, wherein the virtual drive is the entry point of the blockchain file system.

[0043] Specifically, a virtual drive can be mounted to serve as the entry point for the blockchain file system. Specifically, the next-level directories of the virtual drive can include user file directories, transaction template file directories, and contract file directories.

[0044] Step S120: In response to the thread pool of the blockchain file system listening for the file processing request, a blockchain file system callback function corresponding to the file processing request is generated.

[0045] Specifically, once the blockchain is mounted to the local system via a virtual drive, a thread pool for the blockchain file system can be started to listen for designated file processing requests. File processing requests can include, but are not limited to, creating new objects, clearing objects, closing objects, modifying object attributes, reading objects, writing objects, querying object information, querying object storage information, locking objects, setting object description information, refreshing cached content to objects, querying object security information, and setting object security information. The aforementioned objects can include, but are not limited to, folders and files.

[0046] Specifically, a blockchain file system can be implemented, for example, through a file system callback framework, to provide users with blockchain-based interactive operation logic. This allows users to access and operate remote blockchain nodes through the local file system, thereby enabling interactive operations such as transaction on-chaining, information (user, transaction, block) querying, and contract writing.

[0047] Based on the file processing requests monitored by the thread pool of the blockchain file system, the blockchain file system can provide corresponding blockchain file system callback functions, as shown in the table below:

[0048] File processing request Corresponding blockchain file system callback function Create new object BeviosCreate Clean up objects BeviosCleanup Close object BeviosClose Object property construction, querying, etc. BeviosDirectoryInformation Read object BeviosRead Write object BeviosWrite Query object information BeviosQueryInformation Query object storage information BeviosQueryVolumeInformation Locked object BeviosLock Set object description information BeviosSetInformation Refresh cached content to the object BeviosFlush Query object security information BeviosQuerySecurity Set object security information BeviosSetSecurity

[0049] The aforementioned blockchain file system callback function is merely illustrative; other naming conventions are also within the scope of protection of this application.

[0050] Illustrative functional descriptions of callback functions for various blockchain file systems:

[0051] BeviosCreate can be used for on-chain user authentication, creating new local folders, creating new files, etc.

[0052] BeviosCleanup can be used for local file cleanup, releasing the blockchain session connection to which the current file belongs, and freeing up occupied memory, etc.

[0053] BeviosClose can be used to close local files and release occupied memory.

[0054] BeviosDirectoryInformation can be used to modify file system directory tree information, such as folder size limits, file buffers, and file dates.

[0055] BeviosRead can be used for object reading. Specifically, the functionality of BeviosRead varies slightly depending on the object being operated on:

[0056] If the current object is a virtual drive letter, BeviosRead can be used to construct a query request to check whether the current user is an on-chain authenticated user; if not, a request to create a new user is sent to the blockchain.

[0057] If the object is one of the following under a virtual drive: a user file directory, a transaction template file directory, or a contract file directory, BeviosRead can be used for the following purposes, depending on the directory information:

[0058] When the object is a user file directory, it can retrieve the most recent users on the chain and store them in the recent user query file in the local transaction template file directory;

[0059] When the object is a transaction template file directory, it can retrieve the most recent transactions on the chain and store them in the recent transaction query file of the local transaction template file directory;

[0060] When the object is a contract file directory, it can retrieve the most recent contract accounts and contract information on the chain and store them in the most recent contract query file in the local contract file directory.

[0061] BeviosWrite can be used to write objects. If the object is one of the following directories under a virtual drive: user file directory, transaction template file directory, or contract file directory, BeviosWrite can be used for:

[0062] When the object is a user file directory, BeviosWrite is triggered when a user creates a new user file. This function constructs a new user request to the blockchain and retrieves the new user information, which is then stored locally in the user information file. If the user already exists, the function retrieves the user information stored locally in the user information file.

[0063] When the object is a directory of transaction template files, since the directory provides some transaction template files, when a user refers to and creates or edits a new transaction file, BeviosWrite is triggered. The function will check the content of the transaction file, determine whether the text is valid, and construct the transaction and send it to the blockchain after the check is passed.

[0064] When the object is a contract file directory, since the directory provides some contract template files, BeviosWrite is triggered when the user refers to and creates and edits a new contract file. BeviosWrite will scan whether the text content is valid. If the check passes, it will build a new contract for deployment or build a contract call request to the blockchain.

[0065] BeviosQueryInformation can be used to query file or folder information, such as the file object's creation date, last update date, operation attributes, read / write permissions, hidden attributes, etc. This callback function is triggered when a user opens a directory or views the option properties of a file directory or file object (e.g., by right-clicking the object and selecting an attribute from the options list).

[0066] BeviosQueryVolumeInformation can be used to query disk information, such as the creation date, last update date, operation attributes, read / write permissions, and hidden attributes of file objects. This callback function is triggered when a user views the option properties of a mounted virtual disk object (e.g., by right-clicking the object and selecting an attribute from the options list).

[0067] BeviosLock can be used for file object file locking, which is triggered when a user performs an object write operation.

[0068] BeviosSetInformation can be used to set file object properties.

[0069] BeviosFlush can be used to refresh cached content to a file object, triggered when the user saves and refreshes the file object.

[0070] BeviosQuerySecurity can be used to query file security information, and a callback function is triggered when a user views a file object and selects a security attribute.

[0071] BeviosSetSecurity can be used to set file system security attributes, triggering a callback function when the user selects a security attribute for a file object.

[0072] The above is merely illustrative of the functions of each blockchain callback function described in this application, and this application is not intended to limit the scope of the application.

[0073] Step S130: Based on the blockchain file system callback function, interact with the remote blockchain node connected to the virtual drive to obtain blockchain file processing data, so as to execute the file processing of the blockchain file system.

[0074] The file processing method of the blockchain file system provided by this invention uses a virtual drive as the entry point. By operating on files in the virtual drive, the interaction with the blockchain node is converted through the blockchain file system callback function. Through the operation with the blockchain node, relevant information is fed back and displayed in the file system, thereby realizing the file processing of the blockchain file system. This allows users to perform blockchain processing in a familiar file system operation mode.

[0075] Figure 2 This is a schematic diagram of the directory tree of the virtual drive provided by the present invention. Figure 2 This is merely illustrative; the directory tree of the virtual drive letter in this application is not limited to this. Figure 2 The virtual drive letter can be, for example, M:. The next level directory of the virtual drive M: can include a user file directory, a transaction template file directory, and a contract file directory. The user file directory can include folders named after different usernames, which can contain the user's blockchain resource information and transaction history. The contract file directory can include contract files (such as contract template files) and contract query files. The transaction template file directory can include user-created template files, transaction template files, latest transaction query template files, latest block query template files, and default transaction template files, etc. All of the above files can be in TXT format, but this application is not limited to this. Each folder and file can be displayed using existing Windows system folder and file icons, and can also be operated using existing Windows system file operation methods.

[0076] Specifically, the blockchain file system provides a folder creation function: users create new folders (user file directory, transaction template file directory, and contract file directory), fill in the information according to the settings, and save. This step triggers file processing requests (object creation, object reading, and object writing). The object creation request triggers the BeVioSCreate callback function, which checks the new directory name under the virtual drive. If the directory name is not one of the three (user file directory, transaction template file directory, or contract file directory), an error is returned. The object reading function opens the existing set of file directories under the virtual drive and displays them in the current file system interface, triggering the BeviosRead callback function. For the object writing request, when the user opens the virtual drive and attempts to modify any directory name or create a new directory, the BeviosWrite callback function is triggered.

[0077] In each file directory, when a user creates a new file in that directory, a request to create an object and the BeviosCreate callback function will be triggered; when a user saves a file, a request to write an object and the BeviosWrite callback function will be triggered; when a user closes the directory, a request to close an object and the BeviosClose callback function will be triggered; when a user deletes a file, a request to delete an object and the BeviosCleanup callback function will be triggered.

[0078] The user file directory provides a built-in user query function. For example, after a user creates a new user folder using a transaction template, a file named user_file_directory\username.txt will be added to the local virtual drive. This file can contain the user's on-chain storage information and on-chain resources (such as CPU resources, network resources, and random access memory resources). When the user actively refreshes the file, the user information can be synchronously updated and written back to the current file.

[0079] In the transaction template file directory, when a user opens this directory, it will trigger requests to read objects, query object information, and query object storage information, along with corresponding callback functions. When a user creates a new file named <user>.txt, BeviosCreate is triggered, and this callback performs a self-check. <user>Check if the file exists on the chain; if it does not exist, file creation fails.

[0080] In the contract file directory, users create a new file called User-Contract, fill it in according to the format, and save it, which triggers object creation requests, object reading requests, object writing requests, and corresponding callback functions.

[0081] See below. Figure 3 , Figure 3 This is a flowchart illustrating user authentication for the file processing method of the blockchain file system provided by the present invention. In this embodiment, when the file processing operation is accessing the virtual drive, the file processing request includes a file system directory read request, and the blockchain file system callback function corresponding to the file system directory read request is a blockchain file system directory read function. Therefore, Figure 3 The following steps are shown:

[0082] Step S101: Interact with the remote blockchain node connected to the virtual disk to perform on-chain authentication of the user to determine whether the user is an authorized on-chain user.

[0083] Step S102: In response to the user not being an on-chain authorized user, interact with the remote blockchain node to construct the on-chain authorized user corresponding to the user.

[0084] Specifically, the on-chain authorized user can be constructed through transactions. For example, one can interact with a remote blockchain node to request transaction serialization. After obtaining the serialization result, one can request transaction signature data from the blockchain. After obtaining the signature data, one can initiate a transaction request to create an on-chain authorized user. If the transaction is successful, a transaction success certificate is returned.

[0085] Step S103: In response to the user being an on-chain authorized user, save the user information of the on-chain authorized user as an on-chain authorized user file to the user file directory.

[0086] Step S104: Perform public key verification of the on-chain authorized user based on the on-chain authorized user file.

[0087] Step S105: In response to the successful verification of the public key, open the next level directory of the virtual drive letter.

[0088] Therefore, through Figure 3 The steps shown enable user authentication in the blockchain file system. In this embodiment, user identity can be authenticated on-chain. If the user is not an authorized on-chain user, user creation is required. This step involves creating a file system request object and a blockchain-side smart contract, including calling contract methods (user authentication). When a user opens a virtual drive, the blockchain file system self-checks whether it has a remote blockchain user authentication. If not, it attempts to create an on-chain user for authentication. After successful on-chain user authentication, the user can access the virtual drive and perform operations. Otherwise, authentication failure prevents access to the file system workspace of the virtual drive.

[0089] See below. Figure 4 , Figure 4 This is a flowchart illustrating the creation of a folder in the blockchain file system provided by this invention. When the file processing operation is the initial access to the virtual drive letter, the file processing of the blockchain file system further includes the following steps:

[0090] Step S111: In response to the user's folder creation operation on the virtual drive, generate a folder creation request corresponding to the folder creation operation.

[0091] Step S112: In response to the thread pool of the blockchain file system listening for the folder creation request, generate a blockchain folder creation function corresponding to the folder creation request.

[0092] Step S113: Based on the blockchain folder creation function, create one or more folders in the virtual drive, including the user file directory, transaction template file directory, and contract file directory, as the next level directory of the virtual drive.

[0093] Specifically, when a user first accesses a virtual drive, they can actively create subdirectories for that virtual drive. This application can allow the creation of only user file directories, transaction template file directories, and contract file directories as subdirectories of the virtual drive. When a user attempts to create folders with other names, this can be detected by the blockchain file system's thread pool, and an exception will be returned to the blockchain file system driver, thus preventing the creation.

[0094] See below. Figure 5 , Figure 5 This is a schematic diagram of the directory tree construction of the blockchain file system provided by the present invention. When the file processing operation is to access the virtual drive letter or any directory under the virtual drive letter, the file processing request includes a file system directory tree creation request, and the blockchain file system callback function corresponding to the file system directory tree creation request is the blockchain file system directory tree creation function. Therefore, Figure 5 The following steps are shown:

[0095] Step S121: Based on the blockchain file system callback function, interact with the remote blockchain node connected to the virtual drive to obtain the object paths and object information of all files in the currently accessed directory.

[0096] Object information may include, for example, the object name, the size of the buffer occupied by the object, and other object information.

[0097] Step S122: Construct a directory tree for the currently accessed directory based on the object paths and object information of all files in the currently accessed directory.

[0098] Therefore, when a user accesses a virtual drive or any directory (folder) within a virtual drive, a directory tree can be created for display in the file system interface, allowing the user to perform related file operations.

[0099] See below. Figure 6 , Figure 6 This is a flowchart illustrating the directory tree of the blockchain file system provided by this invention, which constructs the transaction template file directory. When the currently accessed directory is the transaction template file directory... Figure 5 Step S122 may also include:

[0100] Step S131: Determine whether the transaction template file directory includes a default transaction template file.

[0101] If not, proceed to step S132: Create the default transaction template file in the transaction template file directory.

[0102] If so, proceed to step S133: construct the directory tree of the currently accessed directory based on the transaction default template file.

[0103] The transaction template file directory includes one or more of the following transaction template files: user-created template file, transaction template file, latest transaction query template file, and latest block query template file. The transaction template file is edited and saved by the user to send the transaction corresponding to the transaction template to the blockchain connected to the virtual disk.

[0104] Specifically, user-created template files, transaction template files, latest transaction query template files, and latest block query template files are all default transaction template files, which contain relevant transaction information for use as templates. Users can edit and save the default information in the template files to send transactions to the blockchain connected to the virtual drive. This application can also provide more different transaction template files, which will not be elaborated here. Specifically, all template files will have their file attributes modified through the BeviosDirectoryInformation callback function to set write operations to be performed only by super administrators.

[0105] See below. Figure 7 , Figure 7 This is a flowchart of the latest block query process provided by the blockchain file system of the present invention. When the file processing operation involves opening or refreshing the latest block query template file, the following steps are performed:

[0106] Step S141: Obtain the latest block information of multiple blocks from the remote blockchain node connected to the virtual disk according to the blockchain file system callback function.

[0107] Specifically, step S141 can obtain the latest block number information by obtaining the latest block height, and then request the latest block information of multiple blocks based on the latest block number information.

[0108] Step S142: Trigger a file write request.
