[0044] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein. Instead, these embodiments are provided to make the present invention comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art.

[0045] The accompanying drawings are only schematic illustrations of the present invention and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware forwarding modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0046] In addition, the processes shown in the accompanying drawings are only exemplary and do not necessarily include all the steps. For example, some steps can be decomposed, some steps can be combined or partially combined, and the actual execution order may change according to the actual situation. The words "first", "second" and similar words 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 the embodiments of the present invention and the features in different embodiments can be combined with each other without conflict.

[0047] The inventors have found in practice that, however, some existing network file systems, such as various network disks, require downloading clients and performing authentication and login. At the same time, data access needs to go through an intermediate server, which makes it impossible to achieve complete data privacy. It can be seen that how to realize a decentralized network-mounted file system is a technical problem that needs to be solved urgently by those skilled in the art.

[0048] The inventors consider applying blockchain technology to the file system to solve the above technical problems.

[0049] Blockchain technology is a decentralized distributed data management framework and has been applied to many distributed system scenarios. Blockchain can realize distributed trusted computing and transactions efficiently and at low cost through a decentralized and unforgeable computing model. It is currently widely used in finance, logistics, industrial manufacturing, medical care, the Internet of Things and other fields.

[0050] Blockchain is decentralized, and each blockchain node is independent of each other. At the same time, smart contracts define the contractual rights of access and depend on the consent of both parties. Entities such as rail transit nodes can participate in blockchain transactions in a limited way or in a more proactive way. Smart contracts mainly provide verification and execution of the conditions set in the contract, allowing trusted transactions without a third party. These transactions are traceable and irreversible.

[0051] The embodiment of the present invention provides a method, device, equipment and medium for constructing a blockchain file system. The inventive concept is to start the file system with a virtual disk as the entry point and process the file processing message of the blockchain according to the blockchain callback registration function set. As a result, the user's reading of files in the file system is not controlled by the central node, and the file storage is completed through the blockchain, achieving complete data privacy and information security.

[0052] Reference Figure 1 , which shows a flowchart of one embodiment of the method for constructing a blockchain file system provided by the present invention. Figure 1 The following steps are shown:

[0053] Step S110: Obtain a source drive letter and a source path as well as a target drive letter and a target path, wherein the source drive letter and the source path are used to connect to the blockchain, and the target drive letter is presented as a local virtual disk.

[0054] Specifically, the source drive letter and the source path are used to connect to the blockchain. For example, the source path may be / opt / block_data. The target drive letter and the target path are local virtual disks. For example, the target drive letter may be G:\\. The source drive letter and the source path and the target drive letter and the target path may be set as required, and the present application is not limited thereto. The switching and updating of the source drive letter and the source path and the target drive letter and the target path may realize the updating of the association relationship between the blockchain and the local virtual disk.

[0055] Step S120: Create a blockchain file system driver.

[0056] Specifically, step S120 can create a globally unique file system driver. In addition, step S120 can perform anti-concurrency settings on the blockchain file system driver.

[0057] Step S130: Setting blockchain file system startup option parameters and blockchain callback registration function set.

[0058] Specifically, before executing step S130, it can be determined whether the blockchain file system driver has been created, and if it is determined to be not, step S130 is executed. If it is determined to be yes, the blockchain file system startup process can be terminated.

[0059] Specifically, the parameter content set in step S130 and the blockchain callback registration function set will be combined with Figure 2 The flowchart shown is described in detail.

[0060] Step S140: Setting a startup message according to the blockchain file system startup option parameters.

[0061] Step S150: Send the startup message to the blockchain file system driver to start the blockchain file system with the target drive letter or target path as the entry, and process the file processing message of the source drive letter or source path according to the blockchain callback registration function set.

[0062] In the construction method of the blockchain file system provided by the present application, the file system can be started with a virtual disk as the entry point, and the file processing message of the blockchain can be processed according to the blockchain callback registration function set, so that it is not controlled by the central node, and the file storage is completed through the blockchain, achieving complete data privacy and information security. The blockchain file system, in which virtual drive letters and folders can be presented to the user in a graphical manner, can also be presented in a command line manner.

[0063] See below Figure 2 , Figure 2 It is a flowchart of setting blockchain file system startup option parameters and blockchain callback registration function set provided by the present invention. Figure 2 The following steps are shown:

[0064] Step S131: Setting the blockchain file system external startup option parameters.

[0065] The blockchain file system external startup option parameters can set true or false for whether network mounting is supported (if not, local disk mapping); whether pluggable mounting is supported; whether the mount is only visible to the current user; whether network unmounting is supported; whether debugging information is supported; whether kernel information printing to user mode is supported. The blockchain file system external startup option parameters can also configure the timeout mechanism (such as timeout period, whether to automatically unmount after operation timeout, etc.); local mount point; network blockchain file system address; number of blockchain file system service threads, etc.

[0066] Step S132: Setting the internal startup option parameters of the blockchain file system.

[0067] The internal startup option parameters of the blockchain file system may include general parameters, mount type parameters, number of threads, timeout, blockchain file system context processing callback function, debugging parameters, and user management permissions for configuration. General parameters may include the current software system version number, whether to support multi-channel streaming access to the same file, and whether to mount to a new local drive letter / path (a drive letter / path that does not currently exist). Specifically, the internal startup option parameters of the blockchain file system may be set according to the settings of the external startup option parameters of the blockchain file system. For example, according to the set external startup option parameters of the blockchain file system, when performing network mounting, the mount type parameter may be set to support network mounting options, support network unmounting options, and set the source mount address at the same time. When performing local mounting, the mount type parameter may be set to support local disk mounting, and the local disk mounting is pluggable mounting. User permission management may be set according to the plug-in method and whether the mount is visible only to the current user.

[0068] Step S133: Set the blockchain callback registration function set.

[0069] Specifically, the file processing message can be analyzed into specific operation messages through the blockchain callback registration function set, such as one or more of the blockchain file system operation message, block operation message, account operation message and contract operation message. The blockchain file system operation message is used to perform one or more blockchain file system operations in the virtual disk size management, obtaining available space, and virtual disk encryption of the blockchain file system. The block operation message is used to perform one or more block operations in block query, transaction query, submission and storage of transactions. The account operation is used to perform one or more account operations in user query and user transaction history query. The contract operation is used to perform one or more contract operations in contract query, contract creation, contract call, contract deletion, and contract update.

[0070] See below Figure 3 , Figure 3This is a flowchart of the second embodiment of the method for constructing a blockchain file system provided by the present invention.

[0071] Figure 3 The parameters required for steps S1401 to S1412 shown in FIG. Figure 2 Configure according to the steps shown.

[0072] Step S1401: Construct a blockchain file system description dictionary.

[0073] The blockchain file system description dictionary is used to maintain a dictionary tree of all file information. Its data format is, for example: [file path name, file description information].

[0074] Step S1402: Construct a blockchain file system description.

[0075] Specifically, the blockchain file system description may include, for example, the software version number, whether it supports multiple streams reading the same file, whether the file name is case sensitive, etc.

[0076] Step S1403: Whether debugging information printing is supported.

[0077] If yes, the information about debugging information printing in the blockchain file system description is set to support debugging printing, and step S1404 is continued. If no, step S1405 is continued.

[0078] Step S1404: Whether debugging driver log information printing is supported.

[0079] If yes, then the information about the debugging driver log information printing in the blockchain file system description is set to support the debugging driver log information printing, and continue to execute step S1405. If no, continue to execute step S1405.

[0080] Step S1405: Whether network mounting is supported.

[0081] Network mounting is used to realize network sharing of blockchain. If yes, the network mounting information in the blockchain file system description is set to support network mounting, and continue to step S1406. If no, continue to step S1407.

[0082] Step S1406: Whether network unmounting is supported.

[0083] Wherein, network unmounting is the unmounting of the corresponding network mount. If step S1406 is judged as yes, the network unmounting information in the blockchain file system description is set to support network unmounting, and step S1408 is continued. If step S1406 is judged as no, step S1407 is continued.

[0084] Step S1407: Whether blockchain file system unmounting is supported.

[0085] If network mounting is not supported, it can be understood that only local mounting is supported. Local mounting only implements local mounting of the blockchain, but does not implement network sharing of the blockchain. Blockchain file system unmounting is the unmounting of the corresponding local mounting.

[0086] If step S1407 is judged as yes, the blockchain file system unmounting information in the blockchain file system description is set to support blockchain file system unmounting, and step S1408 is continued. If step S1407 is judged as no, the blockchain file system description is set to a normal local mount mode, and step S1408 is continued.

[0087] Step S1408: Whether the mount is visible only to the current user.

[0088] If so, the information in the blockchain file system description regarding whether it is visible only to the current user is set to be visible only to the current user, and step S1409 is executed; if not, step S1410 is executed.

[0089] Step S1409: Whether it is a non-ordinary local mount.

[0090] Non-ordinary local mounts are network mounts or do not support removable mount mode.

[0091] If the judgment in step S1409 is yes, the non-ordinary local mount information in the blockchain file system description is set as non-ordinary local mount, and step S1410 is executed. If not, step S1410 is executed.

[0092] Step S1410: Set the number of processing threads and operation timeout duration of the blockchain file system.

[0093] Specifically, the threads of the multiple blockchain file systems are set to form a thread pool, and the blockchain file system processes the file processing message of the source drive letter or source path through the thread pool.

[0094] Step S1411: Set the file node processing context object structure.

[0095] The file node processing context object may include the file node addition function, the file node search function, the file node enumeration function, the file node removal function (remove from the file node information dictionary), the file node move function (move the node from the file node information dictionary to a new location), the file node name acquisition function, the number of file indexes, the file mutex semaphore, the file node description dictionary (a dictionary tree used to maintain all file information: [file path name, file description information]), the definition of the file path description dictionary (a dictionary tree used to maintain all file directory information: [file directory, contained file description information]), and other information definitions.

[0096] Step S1412: Blockchain file system mounting process.

[0097] Specifically, step S1412 can combine the driver parameters set in the above steps S1401 to S1411 with the required blockchain callback registration function set, and realize the mounting of the local virtual blockchain file system through the DokanMain function, thereby realizing the operation and access to the remote blockchain system. Among them, the DokanMain function is a method that can be used to realize file system mounting based on dokany (a user-mode file system driver). The required blockchain callback registration function set can be predefined by the operating system. This application designs and implements these predefined blockchain file system callback functions to realize a set of operation interactions with the remote blockchain system, including: chain information query (block query, transaction query, batch retrieval), chain interaction (deployment of contracts, sending transactions, modification of blockchain storage), on-chain user information access, user history transaction filtering and other functions.

[0098] See below Figure 4 , Figure 4 This is a flowchart of the mounting of the blockchain file system provided by the present invention. Figure 4 The following steps are shown:

[0099] Step S14121: Open the blockchain file system driver.

[0100] Specifically, step S14121 can open the blockchain file system driver created in step S120 by calling an interface function (when applied to a Windows system, the CreateFile interface function can be called). The blockchain file system driver in this application is independent of the upper blockchain file system, and the blockchain file system driver can provide the upper blockchain file system with a system bottom layer interface interaction service.

[0101] Step S14122: Create a blockchain file system instance.

[0102] Specifically, step S14122 can be implemented by the following steps: First, create a blockchain file system instance (for example, create a dokan file system instance instance), and mount the created blockchain file system instance to the global instance queue. Assign the defined attribute information to the created blockchain file system instance. The attribute information may include but is not limited to the number of service threads, blockchain file system global context information, mount point drive name, network mount source information, timeout period, file object expansion unit size, file object reading and writing unit size, etc. Among them, some attribute information can be Figure 3 Steps S1401 to S1411 are defined. Finally, the blockchain file system operation function is assigned to the blockchain file system instance as the blockchain file system basic callback. The blockchain file system operation function may include new file creation, file buffer refresh, file reading and writing, property setting, file list acquisition, etc.

[0103] Step S14123: Start the blockchain file system instance.

[0104] Specifically, step S14123 can notify the blockchain file system driver to mount the target drive letter through the startup time element, and call the system library function to send the startup message to the blockchain file system driver. After receiving the notification message and the startup message, the blockchain file system driver notifies the operating system to allocate the target drive letter as a virtual drive letter and mounts it for the user. The operating system will provide feedback based on the mounting result.

[0105] See below Figure 5 , Figure 5It is a file architecture diagram of the construction method of the blockchain file system provided by the present invention. In the present application, the folder of chain A can be connected through the local virtual disk entrance (D:). The on-chain information, user information, trader and retriever of blockchain chain A can be stored in the folder of chain A in the form of a folder. The folder of on-chain information can store a block list and the transaction history on the chain. The folder of user information can store account lists of different categories. For example, the account information of the account name starting with a is stored in the folder of account list a; the account information of the account name starting with b is stored in the folder of account list a. Further, the resource information and transaction history of each account can be stored in the folder of the corresponding account. The folder of the trader can store the folder of online transaction applications and the folder of evidence storage. The folder of the retriever can store the folder of chain information retrieval and the folder of contract information retrieval. Thus, the chain, transaction, contract, and account are abstracted into folders, and the corresponding file storage inclusion relationship through the above method, and further managed through the above blockchain file system, which is more convenient for users to read blockchain information, submit transactions, modify contracts and other related operations.

[0106] See below Figure 6 , Figure 6 2 is a schematic diagram of the architecture of the blockchain file system provided by the present invention. The blockchain file system may include a blockchain file system architecture 200 and a blockchain system architecture 240. The blockchain file system architecture 200 may include a user-state file system layer 210, a blockchain file system management module 220, and a blockchain interface callback layer 230. The user-state file system layer 210 and the blockchain file system management module 220 may interact with the Windows driver layer 240 and the Windows kernel layer 250 to realize the driving and storage of the blockchain file system. The blockchain system architecture 240 includes a blockchain A chain node 241, a heterogeneous blockchain B chain node 242, and a heterogeneous blockchain C chain node 243 (schematically shown, the present application is not limited to this). The blockchain interface callback layer 230 interacts with the blockchain A chain node 241, the heterogeneous blockchain B chain node 242, and the heterogeneous blockchain C chain node 243 in the blockchain system architecture 240 to use the local virtual disk as the entrance to access the blockchain.

The splitting, merging, changing of the execution order of steps, splitting, merging of modules, and changing of information transmission are all within the protection scope of the present invention.
