Referring to fig. 1-1, fig. 1-1 is a schematic flow chart of a data processing method based on a block chain according to an embodiment of the present invention, where the data processing method based on a block chain is applied to a server, and the method is executed by an execution program of the server, where the server is a terminal device for executing the data processing method based on a block chain, and the server may be a server for providing various services. It should be noted that the data processing method based on the blockchain provided by the embodiment of the present invention is generally executed by a server, and accordingly, the data processing apparatus based on the blockchain is generally configured in the server. As shown in FIG. 1-1, the method includes steps 101-105.
101. And acquiring the transaction information of the user.
In this embodiment, the transaction information may be a plurality of acquired original data, and the transaction information of the user may be acquired through network communication or may be acquired through a database. Generally, a large amount of noise and invalid data exist in the acquired original data, and if the acquired original data are directly used, a large amount of invalid garbage data can be calculated by a calculation server, so that the calculation of the server is easily overloaded, and the server is crashed.
102. And filtering the transaction information of the user through a side chain to obtain target data.
In this embodiment, the interaction between the main chain and the side chain is as shown in fig. 1-2, for example, since the government affair item is open to all citizens or enterprises in this city, any user can fill in the application for the government affair item, so that many unqualified enterprise data are always stored in the database (the transaction information includes many invalid data), and thus the number of nodes of the blockchain is increased, which affects the efficiency of the blockchain. The side chain is an independent block chain, the side chain has an intelligent contract, all enterprises can be registered in the side chain through the intelligent contract, only the enterprise (the target data) preliminarily identified through the intelligent contract is added into the main block chain, and the side chain does not adopt a consensus mechanism, so that the swallowing capacity (TPS) of the system can be greatly improved.
103. Acquiring preset main chain fragmentation information, and acquiring at least one fragmentation region information according to the preset main chain fragmentation information.
In this embodiment, the main chain may be understood as an formally online and independent blockchain network, the fragmentation information refers to a rule of fragmentation, and is specifically applied to how to fragment the main chain, and the rule of fragmentation may be implemented by using an SHA256 encryption algorithm, and after obtaining a result of an encryption operation, performing hash calculation, and obtaining fragmentation area information according to a result of the hash calculation. Or the calculation can be carried out by other methods, and the slicing is calculated according to the specific application scene. Taking Shenzhen administrative regions as the slicing rules as an example, encrypting the region number of each region through an encryption algorithm to obtain an encryption result, then performing hash operation on the encryption result to obtain a corresponding result, and dividing the slicing regions according to the corresponding result. Backbone refers to the collective term for all block chains that adhere to the side chain protocol. The fragmentation area refers to a node area that processes data. For example, how to allocate shards can be determined according to transaction shards, taking Shenzhen as a blockchain main chain as an example, the Shenzhen has 11 regions (main chain shard information), and thus can be divided into a plurality of shards according to the administrative region of Shenzhen, for example, the administrative region of Shenzhen has a Nanshan region, a Longhua region, a Futian region, and a Jean region. The Longhua area and the Baoan area can be divided into a first fragment area, the Nanshan area is divided into a second fragment area, the Futian area can be divided into a third fragment area, the system can allocate one fragment according to the address of a request sender, data submitted by the Nanshan area can be added into the fragment area where the Nanshan area is located if the data passes the verification of an intelligent contract, nodes of all the Nanshan areas can store one fragment, each node is only responsible for hosting own fragment data, and the complete block chain state does not need to be stored.
104. And searching the corresponding fragment area information according to the target data to obtain a target fragment area.
In this embodiment, it can be specifically understood that target data is verified through a preset rule, a corresponding target region is allocated according to the preset rule after verification, such as a certificate number, a unified social credit code, a company type, a legal person/a natural person, to obtain corresponding feature data, and the certificate number is determined as an example, the certificate of the user is the certificate number of the Shenzhen nan mountainous region, and is automatically allocated to the node processing of the Shenzhen nan mountainous region, at this time, a block chain region where the Shenzhen nan mountainous region is a second fragmentation region, and the second fragmentation region (a region formed by nodes of the Shenshan region) is the target fragmentation region. The fragmentation area is composed of a plurality of nodes, and the nodes are the places where the blocks are connected, and the blocks need to be linked for use. The properties of the nodes comprise transparency, openness answer, information non-tampering and decentralization, the fragmentation technology is to divide a chain into individual areas, each area is called a fragment, each fragment bears the function of full time, and the nodes are also dispersed on each fragment to process corresponding work. Therefore, during processing, the transaction information is divided into nodes on the target fragment and processed at the same time, and is distributed as if each department is in work and cooperation, and each node processes only a small part of transactions in the network, so that the processing efficiency of the chain can be naturally and greatly improved.
105. And processing the target data through the target fragmentation area to obtain a processing result.
In the embodiment, the processing result can provide federal service, compliance service and integrated bridge docking service, and multiple versions of SDKs are provided, so that the method is suitable for micro payment and has extremely low commission charge; matching is completed on a distributed transaction chain, so that automatic currency conversion is facilitated; based on time events, multiple signatures and authority hierarchical control, the service safety is higher than the network activity, and an exquisite consensus mechanism provides various APIs (application program interfaces) with access reaching the bottom layer to external applications, so that various commercial applications can be accessed quickly.
According to the invention, the transaction information of the user is filtered through the side chain to obtain the target data, so that the interference of invalid data on the main chain operation is reduced. The preset main chain fragmentation information is obtained, so that the fragmentation region corresponding to the correspondingly processed main chain can be calculated, and finally, the data is distributed to the corresponding fragmentation region for processing, so that the throughput of data processing in the block chain is improved.
In some embodiments, the obtaining of the preset main chain fragmentation information and the obtaining of the at least one fragmentation region information according to the preset main chain fragmentation information includes:
111. acquiring preset main chain fragmentation information;
112. performing hash calculation on the preset main chain fragmentation information by adopting an SHA256 algorithm to obtain transaction hash, wherein the transaction hash at least comprises an id of a user, a transaction timestamp and transaction information of the user;
113. calculating a hash result by using a Const signature (SHA 256(user _ id + tx _ timestamp + tx _ data)), wherein the user _ id represents the id of the user, the tx _ timestamp represents the transaction timestamp, the tx _ data represents the transaction information of the user, and the Const signature is the hash result;
114. generating a transaction proposal by the hash result through a client application programming interface;
115. serializing the transaction proposal into a structured text format to obtain a text transaction proposal;
116. and generating at least one piece of region information for the text transaction proposal according to a private key of an encryption algorithm.
In the above embodiment, the flow chart is as shown in fig. 1 to 3, for example, where shenzhen is taken as an example, shenzhen has 11 regions and can be divided into 11 fragments, the system can allocate one fragment according to an address of a sender, for example, allocate the fragment to a south mountain region for operation, and generate a transaction hash according to information of the south mountain region and a user request, where the transaction hash includes a plurality of transaction information, perform encryption operation through SHA256 to obtain a final encryption result, automatically generate a proposal through an application programming interface, and convert the proposal into a corresponding text through a serialization technology. The security of the transaction can be ensured through the mode.
In some embodiments, after generating at least one piece of region information for the text transaction proposal according to a private key of an encryption algorithm, the method further comprises:
121. extracting target character segments from at least two target data according to a preset rule;
122. and if the target character segments are the same, stopping the transaction.
In the above embodiments, the flow chart is shown in fig. 1-4, for example, when a transaction center company wants to repeatedly submit a government affair item and receive a subsidy, one data contains a plurality of transaction information, such as company name, company address, etc., but the unified social credit code (target character segment) is unique. If there are two target data they appear to be identical to a uniform social credit code. Since the unified social credit code of each enterprise is unique, the double flower phenomenon is judged to occur in this way, and the transaction is stopped. Two times of data are generated for one transaction through the above embodiment, thereby creating double flowers.
In some embodiments, after the searching for the corresponding information of the segment area according to the target data to obtain the target segment area, the method further includes:
131. carrying out randomness fragmentation on the nodes of the target fragmentation area through a randomness fragmentation technology to obtain at least one target processing node;
the processing the target data through the target fragmentation area to obtain a processing result includes:
132. and processing the target data through the at least one target processing node to obtain a processing result.
In the foregoing embodiments and flowcharts shown in fig. 1 to 5, another very important mechanism of the fragmentation technology is a random allocation mechanism, and through the network fragmentation technology, by utilizing randomness, for example, a network can randomly extract nodes by using a VRF method to form fragments, so as to prevent a malicious node from occupying a certain fragment. After the fragment area is obtained, the nodes are randomly extracted for operation, so that a hacker cannot accurately blacken out the corresponding nodes, the cost of hacker intrusion is improved, and the safety of the block chain is improved.
In some embodiments, the filtering the transaction information of the user through the side chain to obtain the target data includes:
141. inputting transaction information of the user to a side chain;
142. extracting feature data from the transaction information of the user through the side chain;
143. and verifying the transaction information of the user according to the characteristic data to obtain target data.
In the above embodiment, the flow chart is as shown in fig. 1 to 6, and first, the user inputs the corresponding information and stores the information in the side chain. And then the side chain checks according to some necessary input information (such as a certificate number, a unified social credit code, a company type, a legal person/natural person), screens out data meeting conditions after checking, modifies the state and synchronizes to the main chain. For example, the enterprise can be declared only for the key enterprise, and whether the enterprise is the key enterprise or not can be judged according to the tax payment amount, the company scale, the company type and the like. Specifically, the transaction information of the user is input into the side chain, corresponding feature data, such as a certificate number, a unified social credit code, a company type, a legal person/natural person, is extracted through a preset extraction rule to obtain the corresponding feature data, whether the part of data is in compliance is checked, and the compliance rule is determined as target data.
In some embodiments, the extracting feature data from the transaction information of the user through the side chain includes:
151. creating a database main library and a block chain side chain, wherein the block chain side chain is a plurality of extensible channels;
152. constructing a transaction proposal based on the transaction information, and sending the transaction proposal to the corresponding expandable channel;
153. preprocessing the transaction proposal through the side chain to obtain characteristic data;
154. storing the feature data into the blockchain side chain;
155. sending blocks of the block chain side chains into the main chain.
In the foregoing embodiments, the flow charts are shown in fig. 1 to 7, where each of the extensible channels corresponds to a channel database; the database is used for creating a developer user table, the extensible channels are used for receiving transactions of developer users, and each developer user is added into one extensible channel.
In some embodiments, after the processing the target data by the target sharded area, the method further comprises:
161. verifying whether the format of the processing result is correct;
162. if the format of the processing result is correct, verifying the processing result through a public key of the encryption algorithm to obtain a verification result;
163. and if the verification result is successful, storing the processing result in a database.
In the above embodiment, the flowcharts are shown in fig. 1 to 8, since the data stored in the database should satisfy the preset rule arrangement, if the arrangement of the data is different, the data cannot be stored in the database. And when the processing result meets the storage format of the database, if the format meets the uploading requirement, the processing result is verified through an encryption algorithm, and if the processing result cannot be decrypted through a public key, the data is not stored. Whether the processing result is correct is verified through the method. Preventing erroneous results from being saved to the database.
The technical method can be applied to application scenes including data processing based on block chains, such as intelligent government affairs, intelligent city management, intelligent community, intelligent security protection, intelligent logistics, intelligent medical treatment, intelligent education, intelligent environmental protection and intelligent traffic, so that the construction of intelligent cities is promoted.
