In step S4, the blockchain system provides the access terminal with a contact method for interfacing with the entity data provider according to the contact request of the access terminal, so that the access terminal can obtain the private key from the entity data provider.
It should be noted that, after finding the identity of the offline entity matching the requirement, the access end may request the blockchain system to acquire the contact information of the data provider of the offline entity to contact the data provider, and access the entity publicity information stored in the intermediary server through the private key provided by the data provider, thereby implementing the early-stage network screening before accessing the offline entity and improving the house renting efficiency.
It should be noted that, in this embodiment, the entity data provider only needs to register in the blockchain system, and does not need to register in each intermediary server, so that the complicated procedures can be reduced, data leakage can be avoided, and the data can be prevented from being used commercially or even illegally when the data is not allowed.
In addition, the entity data providing end can control the use state of the entity data under the control line through the private key, and the entity propaganda data can be inquired and retrieved by visitors on the block chain system through the meta-information of the entity propaganda data, so that the purpose that the data is generated by the visitors and the visitors benefit is fully realized.
It should be noted that the visitors can track the offline entities matching their own needs through the blockchain system without registering on various rental agency platforms one by one, which not only prevents personal data from being improperly used, but also makes rental more efficient and easier.
It is noted that, due to the simplification of the network communication procedures of the entity data provider and the access terminal, the network resources, for example, the bandwidth, are also greatly saved.
In a preferred embodiment, the step of providing the access terminal with the contact information of the data providing terminal of the docking entity according to the contact request of the access terminal includes:
acquiring a contact way of an access terminal to generate a dynamic verification code;
and providing the contact information of the entity data providing end to the access end according to the dynamic verification code.
It should be noted that, in the preferred embodiment, the blockchain system obtains the contact way of the access terminal, generates the dynamic verification code, and sends the generated dynamic verification code to the access terminal for input confirmation, and the blockchain system provides the contact way of the entity data providing terminal to the access terminal according to the dynamic verification code.
In an improved embodiment, the decentralized data storage access method further comprises:
obtaining access feedback after an access terminal accesses an offline entity, and forwarding the access feedback to a down-link verification node;
sending the contact information of the entity data providing end to the down-link verification node, so that the down-link verification node can be used for obtaining a private key by butting the entity data providing end, and comparing the access feedback with the entity propaganda material to obtain a verification opinion;
and obtaining the verification opinions for link storage and publishing in the whole network.
It should be noted that, the technical effect brought by the improved scheme is as follows:
firstly, the entity propaganda material is stored in the intermediate server, so that the storage pressure of the block chain system can be reduced, and the throughput and the processing efficiency of the block chain system are improved;
secondly, the entity propaganda materials are stored in the intermediate server, and the entity propaganda materials are accessed only after the entity data providing end obtains the access private key, so that the data security of the entity propaganda materials is ensured;
thirdly, as the intermediate server stores the entity propaganda material, the down-link verification node can objectively check the access feedback and the entity propaganda material after acquiring the private key, thereby strengthening the authenticity. Meanwhile, the technical skill of the isolation processing of the entity propaganda data and the entity propaganda data meta-information is skillfully considered, the storage burden and the verification burden of the block chain system are reduced as a whole technology, and the transaction throughput of the block chain system is greatly improved;
fourthly, since the verification work is carried out by the verification node under the chain, and the access feedback is not the data information which needs to be verified in time in the blockchain system, the verification burden of the blockchain system is relieved, and the transaction throughput of the blockchain system and the response speed of timely verifying the timely verification information are enhanced.
In an improved embodiment, the verification opinions are acquired and stored in a link mode, and the step of publishing the whole network comprises the following steps:
obtaining verification opinions and storing the verification opinions into a buffer pool;
and after a preset period, the verification opinions in the buffer pool are subjected to link storage and are published in the whole network.
It should be noted that, because the type of the verification opinions in the entity lease is not the timely verification information, the blockchain system can be treated differently, and a mode of automatic publishing after the preset time is used is utilized, so that the technical effect of better controlling the transaction throughput of the blockchain system is achieved.
It should be further noted that the buffer pool may be a temporary database for storing some data with a priority not very high, so as to relieve the data processing pressure of the blockchain system.
Example two
