Embodiment 6

The above embodiments have already elaborated on the data processing method, apparatus and system based on the blockchain technology; the embodiments of the present application will further describe the specific applications.

In practical applications, the data processing method based on the blockchain technology of the above embodiment is specifically described by taking the case of our company's easy-to-use system (hereinafter referred to as Fangyixin) as an example.

The real estate information data source of Fangyixin includes the self-built real estate credit database and the housing management bureau database. Among them, the self-built real estate credit database stores at least the users of Fangyixin, developers, second-hand housing transaction brokers, housing information consultants, etc. The obtained property information data can also store real estate information data such as real residence and residence information, water and electricity fee information, property fee information and family situation; in other words, the self-built real estate credit database mainly stores the central platform for the credit to be used. Property information data imported on the blockchain. What needs to be explained here is that the establishment of the real estate information data source of Fangyixin is the first step of digitalization of real estate, and also the prerequisite for realizing the credit transformation of real estate liquidity.

For the generation of the basic unit information of the block in the central credit platform of the website, and how to add the new block to the blockchain, the following description is given, as shown in FIG. 8 , which is the central platform of the Fangxin credit provided by the sixth embodiment of the present application. The block diagram of the blockchain shows that the block basic unit information in the blockchain of the Fangxin Credit Central Platform can be understood as the important structured information of the real estate:

First, collect property information data from property information data from the built-in property credit database, and property information data obtained through establishing an information connection with the Housing Authority database.

Secondly, the property information data is classified according to the attribute of the real estate information data, and the data processing processing is performed on different types of real estate information data after classification; specifically, the real estate information data identifying the fixed length type and the importance degree attribute is the first Type of information (It can be important information related to the valuation of the property, including the number of a house title certificate.) Since the number of the house title certificate has fixed length type attribute as fixed length information, the blockchain technology can directly process the type information, so The first type of information can be written into the real estate to involve important structured information; the real estate information data identifying the non-fixed-type and/or non-important attributes is identified as the second type of information (eg, by the user, development Real estate information data obtained by commercial, second-hand housing transaction brokers, housing information consultants, etc., due to the property information data obtained by Fangyixin users, developers, second-hand housing transaction brokers, housing information consultants, etc. Fixed-length and/or non-important attributes, blockchain technology can not directly deal with this type of information directly, it is necessary to calculate the length of such property information data, and write such property information data after the fixed length calculation Entry into the property involves important structured information; it is important to emphasize that the fixed length included in such property information data with non-fixed-type and/or non-important attributes Information of type and non-importance attributes, although having one side of the fixed-length type attribute but limited by the non-importance attribute, cannot be directly written into the property involving important structured information; it is important to emphasize whether the information is important or not. The overall planning can be determined according to product requirements and/or product definitions, and details are not described below; the fixed length calculation mentioned in the embodiment of the present application may be a digest calculation (ie, a hash algorithm) in the field of computer cryptography, The main feature is that the input of any length can be changed to obtain a fixed length output, which can be understood by those skilled in the art and is expected to be a correlation algorithm as long as the input of any length can be changed to obtain a fixed length output. It can be adopted by the embodiment of the present application, and belongs to the protection scope that supports the interpretation of "fixed length calculation"; the following is described by using a hash algorithm as a fixed length calculation (fixed length calculation preferred hash (Hash) algorithm) Because of the irreversible nature of the hash algorithm, it ensures that the property involves irreversible modification of important structured information. Greatly enhance the room credulity credit database data center platform block chain credibility.

Next, package the first type of information that has been written into the property involving important structured information (which can be important information about the valuation of the property, including the number of a house title certificate) and the second type of information after the fixed length calculation (eg Real estate information data obtained by Fangxinxin users, developers, second-hand housing transaction brokers, housing information consultants, etc., and combined to generate real estate It involves important structured information.

Specifically, it should be noted here that the second type of information (such as real estate information data obtained by the user, developer, second-hand housing transaction broker, housing information consultant, etc.) may be fixed length calculation. Including the following ways, you can choose one according to the actual needs:

The first way is to merge all the second type information and perform fixed length calculation on the combined second type information. That is, the second type of information as a whole, after the Hash algorithm operation, can output the existence proof of all the second type information after the merger, and the existence proof will be written into the real estate involving important structured information. As part of an important structured information about the property;

The second way: performing fixed length calculation on each of the second type of information to obtain the proof of existence of each of the second type of information, and merging all the existence certificates. That is, each piece of information in the second type of information is separately processed by a hash algorithm, and then the respective proofs of existence of all the second types of information are merged, and the proof of existence will be written into the real estate involving important structuralization. Information as part of a property that involves important structured information;

The third mode: grouping all the second types of information, the rules of the grouping may be determined according to the definition of the product requirements, the relevance of the information, etc., wherein each group includes at least one piece of the second type of information. And at least one group includes a plurality of second type information, for example, grouped into a second type of information; and the second type of information in the group including the plurality of second type information is merged, and the information includes a single second type information The grouping may not perform the combining step, and perform fixed length calculation on the combined second type information in each group to obtain the existence proof of the second type information of each group, and merge all the existence certificates. That is, the second type of information is grouped according to the grouping rule, and the second type of information is grouped as an example, the information in the second type of information group is merged, and then the hashing algorithm is operated in units of groups, and then all the units are merged. Proof of the existence of each of the two types of information, and the proof of existence will be written into the property involving important structured information as part of the important structured information involved in the property.

Further, the embodiments of the present application involve important structured information along with the above-mentioned real estate. The large-scale generation with time continuation will collect at least one of the real estates involved in the construction of at least one of the real estates according to the preset interval time and according to the processing capacity limitation and the current property to be processed, and involve important structured information into the new block. To generate a new block; for example, the preset time interval of the preset condition is 1 minute to enter a new block, and the current property to be processed involves important structured information of 1w, and is processed in a preset condition. When the capacity limit is only 6k, after 1 minute of the preset interval, due to the limitation of the processing capacity in the preset conditions, the property that collects the organization into the current new block involves 6k important structured information, and the remaining 4k properties involve The important structured information will collect the organization into the next new block; for example, the preset time interval of the preset condition is 1 minute to enter a new block, and the property to be processed currently involves important structuring. The information is 4k, and the processing capacity limit is only 6k in the preset condition. After the preset interval is 1 minute, the preset condition is not reached. Limiting the capacity, collecting property into the current new block involves 4k pieces of important structured information;

Further, the block chain miner combines important structured information on at least one property that has entered the new block. In the process, a time stamp may be added to the generated new block, and the time stamp may be determined. Packing at least one property for the merger involves the start or end time of important structured information, or extracting the time information of important structured information from the last property entering the new block as a time stamp; in addition, it can also be involved for each property. Important structured information performs signatures and/or performs overall signatures on new blocks to ensure data security during transmission; of course, new blocks are successfully added to the blockchain, depending on the actual needs of the blockchain Some other block control information can be freely added by those skilled in the art according to the research and development requirements, and will not be enumerated here. Thus, as shown in FIG. 8, the new block may include at least one of the properties involved in important structured information, time stamps, signatures, other block control information, and the presence of a hashed hash of the previous block. Sexual proof; further, the existence test of the new block and the previous block of the fixed length calculation (Hash algorithm) is carried out to link the new block to the previous one in the blockchain of the Fangxin Credit Central Platform Block.

In practical applications, the first type of information (information related to property valuation) that identifies the type of fixed length and importance attribute in the property information data is based on the house title number. For the unique index, according to the collection time of the property information data, the blockchain of the Fangxin Credit Central Platform is sequentially accessed; in addition, the second type information of the non-fixed type and/or importance attribute is identified in the property information data. It can be called other property information data, and can be stored in the out-of-band storage system based on the existence of blockchain. Fangyixin calculates the hash value for these existence proofs (Hash algorithm). And the hash value is included in the blockchain of the Fangxin Credit Central Platform.

FIG. 9 is a chain structure composed of important structured information provided by the sixth embodiment of the present application. As shown in Figure 9, due to the inherently high degree of transparency and information tampering inherent in the blockchain of the Fangxin Credit Central Platform, it can be further understood that the property with logical housing number as the sole index involves important structured information. The self itself also forms a chained data structure, which is different from the packaged in the block and then forms a chain structure in the form of a blockchain. Through the organization of the above property information data, Fangyixin has established a set of chained and generalized digital data records of real estate. The chained data organization form enables the real estate database of Fangyixin to collect new real estate from historical data. The truth and rationality of the information is verified by business in the form of big data analysis. From the information content, in addition to the inherent information of the house, the Fangxin system can also selectively add household information and household information, etc. The irreversible modification of the data is guaranteed by the technology of the blockchain, which greatly enhances The credibility of the data in the Fangyixin real estate database also laid the foundation for the real estate valuation system of Fangyixin.

The room information system provided by the embodiment of the present application stores the alternate property information data of the block chain of the Fangxin credit central platform through the real estate information data source; the real estate involves an important structured information generating device to collect the real estate information source data. The information data is summarized and summarized; the information is classified according to the attributes of the real estate information data, and the data processing of different types of real estate information data after classification is processed; the processing results of different types of real estate information data are packaged, and the generated real estate involves an important structure. According to pre-set conditions, the blockchain miner organizes at least one property involving important structured information into the new block and links the new block to the previous block in the blockchain of the Fangxin Credit Central Platform. Related technical solutions; encrypting plaintext including complex and variable length information into ciphertext by fixed length calculation, and combining the plaintext of the fixed length information and the ciphertext into the blockchain, thereby ensuring It proves that the plaintext is stored and not falsified in the entire blockchain; and through the classification and processing of the complex and variable length information and fixed length information in the plaintext, the existing blockchain technology cannot solve the complicated And the technical problem of variable length information, the purpose of complex and variable length information can be written into the blockchain in a block manner.
