[0038] The audit and traceability module is used to provide an audit function to ensure the transparency of the device management platform.

[0039] In some embodiments, the data storage system comprises:

[0040] A data storage framework module, wherein the data storage framework module is used to construct a hierarchical data storage model;

[0049] The permission audit and log management module is used to audit and effectively manage various logs;

[0050] The authority management strategy and approval process module is used to implement authority management and perform approval according to the process.

[0051] Another technical problem to be solved by the present invention is to provide a decentralized verification method for a blockchain device management platform, comprising the following steps:

[0052] Step 1: First, complete the information collection of each device and establish the device status model;

[0053] The device ID is a unique identification code assigned to each device to distinguish different devices;

[0054] Device model records the model information of each device, which is used to distinguish different versions of the device;

[0055] Production Date records the production date of each device, which serves as a key reference for device life cycle management;

[0056] Manufacturers record the manufacturer information of each device, which is helpful for after-sales service and warranty management of the equipment;

[0057] The device type records the category to which each device belongs, which helps the system to classify and manage devices;

[0058] The device status records the initial status of each device, ensuring that the management of the device lifecycle can be tracked from the beginning;

[0059] The device description information records the functions and application scenarios of each device, which helps device managers better understand the usage of the device;

[0060] Step 2: After collecting device information, format the basic information of the device, convert the device information into JSON format, and then encrypt the device information through RSA encryption to ensure the privacy of the information;

[0061] Step 3: Package the formatted device information into a blockchain transaction. Each device information will generate a unique hash value, which will be used as the transaction master to ensure that the device information cannot be tampered with. The verification nodes in the network will verify and confirm it.

[0062] Step 4: When the device information is successfully registered and written into the blockchain, it will be permanently stored in the distributed ledger of the blockchain. In order to improve query efficiency, the device registration module usually establishes an index database off-chain to store the basic index of device information. This index database can help users quickly query relevant information of the device;

[0063] Step 5: In order to avoid duplicate registration of device information, when registering a device, the system will query whether the device ID already exists through the blockchain network. If the device ID already exists, the system will prompt the user that the device has been registered to avoid duplicate registration; if the device ID does not exist, the system will generate a new unique identifier for the device and complete the registration;

[0064] Step 6: Once the device information is successfully registered to the blockchain and confirmed by the blockchain network, the device owner or administrator will receive a notification of successful registration. At this point, the device information has been officially stored in the blockchain and can be queried and verified by the device ID;

[0065] Step 7: Store all kinds of data in the blockchain network for storage;

[0066] Step 8: The system is based on the state change threshold within the smart contract. When the device state changes, the system will record the specific information of the state change;

[0067] Step 9: Staff can observe changes in device status in real time, and all types of change data and operation logs will be stored in the blockchain.

[0068] Compared with the prior art, the present invention provides a blockchain device management platform and a decentralized verification method thereof, which have the following beneficial effects:

[0069] The blockchain device management platform and its decentralized verification method use blockchain technology. The data of each device cannot be tampered with, ensuring the authenticity and integrity of the device status and historical information. At the same time, the operation records and status changes of each device, including the operator information, will be retained on the blockchain. Users can query the usage of the device at any time to ensure the transparency of the management process.

[0070] At the same time, decentralized verification is used, which does not rely on a single central server, avoiding the risk of single point failure in centralized systems and improving the stability of the system. By automating the equipment management process through smart contracts, it can effectively reduce errors and delays caused by manual intervention and improve management efficiency.
