receiving a device change instruction from a supervisory node, and updating the initial device information according to the device change instruction, or receiving data reporting information from an authentication node, wherein the data reporting information comprises the updated device information;
and storing the updated device information in the data sharing system.
The production node is a platform of a producer of the device, and may specifically be a terminal device or a server of the producer, and may perform authentication in the blockchain, where the authenticated production node may be responsible for registering initial device information of each produced device in the blockchain, where the initial device information may include a device identifier, hardware usage information of the device (initial is 0, that is, brand new), and the like.
In addition to reporting the hardware usage information to the block chain for storage as the authentication node in the device usage process as described above, the block chain may further be provided with a supervisory node, and the supervisory node may be a maintenance organization, a device inspection station, and the like registered in the block chain and authorized to acquire, detect, and correct the hardware usage information of the device.
The supervision node can be combined with manual work to check and maintain the equipment, inquire the hardware use information and verify whether the recorded hardware use information is correct or not through professional means. For example, an administrator of the supervisory node may store information obtained by checking the device to the blockchain network through a device information intelligent contract preset by the blockchain, and the method may include: IMEI, historical transaction, maintenance information, valuation information, owner information and the like, and for equipment information intelligent contracts, only an account address of the contract is deployed and the contract is authorized to be called. Meanwhile, the initial equipment information can be modified and updated through an equipment change instruction, and new equipment information is obtained and recorded in the block chain.
303. And verifying whether the hardware using information is consistent with the hardware using information of the target terminal issued by the second node or not, and obtaining a verification result.
Specifically, for the acquired hardware usage information, the hardware usage information of the target terminal issued by the seller can be compared with the acquired hardware usage information to verify whether the hardware usage information is consistent, so as to assist the user in judging whether the detailed introduction of the seller product is real or not and selecting whether to perform a transaction or not.
Because parameters in some hardware use information are complex, a buyer can not accurately judge directly by inquiring and comparing, so the blockchain server can firstly perform data comparison to obtain a verification result, more generally and intuitively obtain the authenticity of the hardware use information, and give conclusive judgment, such as what the real hardware use information is, how many times the hardware use is higher or lower than the information introduced by the seller, and the like, without limitation.
304. If the verification result is inconsistent, reducing the credit score of the second node; broadcasting the verification result in the data sharing system.

The reputation evaluation and the penalty measure in the embodiment of the application can be realized in a specification mode by an intelligent contract.
The intelligent contract is a contract which uses a computer language to record the clause content instead of a legal language, the intelligent contract deployed on the blockchain is a digital contract which can execute contract codes on a CPU, and when the clause content of the intelligent contract is met, predefined rules and clauses can be automatically executed. In an alternative embodiment, the penalty measure may be recorded in the intelligent contract, and when the nodes violate the intelligent contract specification, or the reputation score of each node is lower than a score threshold, the execution of the intelligent contract may be triggered, and the corresponding cost is paid according to the corresponding penalty specification in the intelligent contract.
Optionally, the penalty measure may further include:
and limiting the information uploading times of the second node in the investigation time, or recording the second node in a blacklist of the data sharing system, wherein the nodes in the blacklist prohibit information uploading and the like.
Optionally, if the verification results are consistent, the verification result may also be sent to the first node, which indicates that the hardware usage information provided by the seller is reliable, and may suggest to the buyer to purchase the target device.
