In an embodiment of the present application, the interaction platform is a blockchain node in the blockchain network for coordinating transactions of device data between the first blockchain client and the second blockchain client. The first blockchain client refers to an interactive client installed in an electronic device of a device provider that typically needs to purchase device data generated by the device in daily operation from the device owner. The second blockchain client refers to an interactive client installed in the electronic device of the device owner. Each interactive client belongs to one blockchain node in the blockchain network, and the installation package of the interactive client can be stored in advance in each blockchain node of the blockchain network in a distributed mode by using an IPFS (Inter Planetary File System, interstellar file system), and after the equipment provider and the equipment owner can join the blockchain network, the installation package is downloaded from the blockchain network and installed in the electronic equipment of the installation package. The block chain network is a decentralized distributed account database composed of block chain nodes, wherein all the block chain nodes can communicate with each other to form a peer-to-peer network structure, and data generated by one block chain node can be simultaneously broadcast to other block chain nodes in the block chain network and can also be inquired and acquired from other block chain nodes. In the embodiment of the application, the blockchain node refers to a first blockchain client and a second blockchain client which participate in device data transaction and an interaction platform responsible for coordination work between the first blockchain client and the second blockchain client.
The device data requirement information may be input by the device provider according to its own requirement through the first blockchain client, for example: equipment basic information such as equipment name, equipment manufacturer, equipment model, equipment parameter name, equipment operation year and the like, time range of data generated by equipment in the operation process, parameter type, parameter value, association relation between parameters and product qualification rate and the like.
In practical application, the equipment provider is in need of optimizing and improving the produced equipment according to the equipment data produced in the running process of the equipment, equipment basic information of a second blockchain client in the interactive platform can be checked through the first blockchain client, the equipment basic information is uploaded to the interactive platform when the equipment owner accesses the blockchain network, and the interactive platform also integrates the equipment basic information and then checks the equipment basic information through the first blockchain client or other blockchain link points in the blockchain network.

And the second blockchain client uploads the device data integrated by the device owner according to the device data demand information to the blockchain network for distributed storage. However, since the data in the blockchain network is stored in an encrypted manner, if the data identification is needed to be queried, that is, the unique hash value of the data, the second blockchain client generates the data identification of the device data for storage when uploading the device data, and other users cannot query the device data from the blockchain network when not obtaining the data identification, so that the security of the storage of the device data can be ensured.
A distributed storage method of device data is provided with reference to fig. 2, in which device data corresponds to a unique hash value as a data identifier, and the device data is split into a plurality of data fragments to be stored in respective blockchain nodes of a blockchain network.
In practical application, because the device data has replicability, if the device data is directly and completely provided for the first blockchain client for the device provider to view, there may be a situation that the device data is infinitely duplicated without authorization of the device owner, so before the device data is provided for the first blockchain client, the device data can be subjected to desensitization processing, so that the device provider can view the desensitized device data through the first blockchain client before the transaction of the device data is completed, the situation of the device data is approximately known, and the security of the device data is ensured.

In practical application, after the equipment provider checks the desensitized equipment data, an intelligent contract generation instruction can be sent to the interactive platform through the first blockchain client side of the equipment provider, so that the interactive platform is triggered to generate an intelligent contract related to the equipment data on the blockchain platform, wherein the intelligent contract can comprise conditions required to be achieved by the first blockchain client side and the second blockchain client side, the conditions required to be achieved by the second blockchain client side are conditions required to be met by the equipment data provided by the second blockchain client side, the conditions required to be achieved by the first blockchain client side can be specifically set by the second blockchain client side, contract amount and the like can be automatically generated according to parameters such as data quantity and data complexity of the equipment data, and the intelligent contract can be specifically determined according to practical requirements, and the intelligent contract is not limited.

Thus, the equipment manufacturer of the first blockchain client can trade the equipment data with the factory of the second blockchain client through a transaction certificate, wherein the transaction certificate is a verification identifier provided by the blockchain network to the first blockchain client.
