Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

The terms referred to in the examples of the present application are explained as follows:

block chain (Block chain): the method is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like. The blockchain is essentially a decentralized database, which is a string of data blocks associated by using cryptography, each data block contains information of a batch of network transactions, and the information is used for verifying the validity (anti-counterfeiting) of the information and generating the next block. The blockchain may include a blockchain underlying platform, a platform product services layer, and an application services layer.

The block chain underlying platform can comprise processing modules such as user management, basic service, intelligent contract and operation monitoring. The user management module is responsible for identity information management of all blockchain participants, and comprises public and private key generation maintenance (account management), key management, user real identity and blockchain address corresponding relation maintenance (authority management) and the like, and under the authorization condition, the user management module supervises and audits the transaction condition of certain real identities and provides rule configuration (wind control audit) of risk control; the basic service module is deployed on all block chain node equipment and used for verifying the validity of the service request, recording the service request to storage after consensus on the valid request is completed, for a new service request, the basic service firstly performs interface adaptation analysis and authentication processing (interface adaptation), then encrypts service information (consensus management) through a consensus algorithm, transmits the service information to a shared account (network communication) completely and consistently after encryption, and performs recording and storage; the intelligent contract module is responsible for registering and issuing contracts, triggering the contracts and executing the contracts, developers can define contract logics through a certain programming language, issue the contract logics to a block chain (contract registration), call keys or other event triggering and executing according to the logics of contract clauses, complete the contract logics and simultaneously provide the function of upgrading and canceling the contracts; the operation monitoring module is mainly responsible for deployment, configuration modification, contract setting, cloud adaptation in the product release process and visual output of real-time states in product operation, such as: alarm, monitoring network conditions, monitoring node equipment health status, and the like.

The platform product service layer provides basic capability and an implementation framework of typical application, and developers can complete block chain implementation of business logic based on the basic capability and the characteristics of the superposed business. The application service layer provides the application service based on the block chain scheme for the business participants to use. For example, the credit platforms of each level related in the present application may include a national credit platform, a municipal credit platform, a provincial credit platform, a county and district credit platform, a commission and office credit platform, a public service unit credit platform, a public transportation service unit credit platform, and the like, and the credit platforms of each level include a background service and a client; the background service is located on a platform product service layer, and the client is located on an application service layer. The client provided by each credit platform is used for providing an execution entrance for the user in the implementation process of the credit combined reward and punishment system. For example, a user may submit a project administrative approval application through one client, and perform project administrative approval through another client; for another example, the user may submit a credit repair application through one client and perform a credit repair audit through another client.

Block chains can be divided into private, federation, and public chains; here, the alliance chain is also called a community Block chain (Consortium Block chains), and refers to a Block chain whose consensus process is controlled by a preselected node. In the alliance chain, all or part of functions are opened only for the node members in the chain, and each block chain link point in the alliance chain can customize read-write permission, query permission and the like based on needs. For example, in the block chain-based credit union reward and punishment system provided by the application, all credit institutions at all levels of the country can be used as node members of a union chain, and the union chain opens the permissions of reading, writing, querying and the like for the node members.

Consensus mechanism (Consensus mechanism): the block chain system is a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes. In the block chain system, the verification and confirmation of the transaction can be completed in a short time through the voting of special nodes, and if a plurality of nodes with irrelevant benefits can achieve consensus on a transaction, all the nodes in the system can also achieve consensus on the transaction.

Smart contract (Smart contract): is a computer protocol intended to propagate, validate or execute contracts in an informational manner. Each node in the blockchain system can automatically execute a contract program according to a specific condition, can operate data stored in the chain, and is an important way for a user to interact with the blockchain and realize business logic by using the blockchain. The goal of smart contracts is to provide a secure method over traditional contracts and to reduce other transaction costs associated with the contracts, which allows for trusted transactions that are traceable and irreversible without third parties.

A credit combined reward and punishment mechanism is formally established in 2016 in China. The credit joint reward and punishment mechanism is divided into two parts of credit joint incentive and credit loss joint punishment and relates to each side in a social system; for example, the field of traffic, industry and commerce, tax field, etc.; through the cooperative adoption of incentive and punishment measures by governments, markets and society, the credit-keeping income and the loss cost are improved, and the credit-keeping person is led to be in a green light way and is limited everywhere. The incentive measures can include administrative examination and approval of 'green channels', declaration of 'acceptance of deficiency', reduction of daily supervision frequency and the like; the disciplinary measures can include limiting the purchase of airline tickets, limiting the purchase of high-speed rail tickets, limiting the operation of responsible persons, director, prisoners and high-level managers of enterprises, limiting the departure, limiting financing and credit, limiting the acquisition of government funds, implementing strict supervision of import and export goods clearance, stopping or forbidding the search of group chatting related to 'bill swiping' and 'credit stir-frying', stopping illegal 'credit-stir-frying' enterprises and the like.

In order to implement the credit combined reward and punishment mechanism, a credit combined reward and punishment system is constructed, and is used as an implementation carrier of the credit combined reward and punishment mechanism, and the credit combined reward and punishment system is provided with a plurality of levels of credit platforms of China, provinces, cities, counties and the like. Due to the construction dispersion of the multi-stage credit platforms, the synchronous real-time performance of the personal/enterprise credit information in the credit combined reward and punishment system is poor, so that the credit information in each stage of credit platform is inconsistent; for example, to repair credit for individuals/enterprises, the individuals/enterprises need to go up to be examined and approved layer by layer through the city, province and national credit institutions, and finally the examination and approval results cannot be returned to the city-level credit platform in time. In addition, whether the credit union reward and punishment system is applied according to the national requirements in the service approval process of each commission and office can not be effectively supervised.

Therefore, the credit combined reward and punishment system based on the block chain is provided, the credit information is synchronized in each node in the system by using de-centralization of the block chain, and the problem of inconsistency of the credit information in credit platforms at all levels is solved. Referring to fig. 1, which shows a schematic node distribution diagram of a block chain based credit joint reward and punishment system 100 provided in an exemplary embodiment of the present application, a node 120 of the block chain based credit joint reward and punishment system 100 may include a national credit platform, a municipal credit platform, a provincial credit platform, a public transportation service unit credit platform, a county and district credit platform, a municipal commission office credit platform, a public utility unit credit platform, and the like; building block chains based on the nodes 120; optionally, the block chain may include a federation chain.

The node 120 provides credit union reward and punishment related services for each level of mechanisms 140 of related departments, units, institutions and the like. For example, the credit platform of the public transportation service unit provides a credit inquiry window for transportation service departments such as aviation, railway and the like through the application program 160; the county and district credit platform provides a credit inquiry window for a district administrative service center and each street town of a county and district through an application program 160; the credit platform 160 of the market commission office provides credit union reward and punishment related services in business systems of institutions such as market industry and commerce, market medicine supervision, market environmental protection, market tax and the like; the public service unit credit platform provides a credit inquiry window for units such as water, electricity, coal and the like through an application program. Illustratively, the application 160 may be a joint reward and punishment micro-portal, that is, an applet, and the applet provides credit joint reward and punishment related services by implanting the applet in the system of each stage of the mechanism 140.

It should be noted that the credit union reward and punishment system 100 based on the block chain may be used as a data sharing system, and is configured to perform data sharing between nodes, as shown in fig. 2, the data sharing system is simply illustrated based on fig. 1, the data sharing system may include a plurality of nodes 201, and the plurality of nodes 201 may refer to each client in the data sharing system. Each node 201 may receive input information and maintain shared data within the data sharing system based on the received input information while operating normally. In order to ensure information intercommunication in the data sharing system, information connection can exist between each node in the data sharing system, and information transmission can be carried out between the nodes through the information connection. For example, when an arbitrary node in the data sharing system receives input information, other nodes in the data sharing system acquire the input information according to a consensus algorithm, and store the input information as data in shared data, so that the data stored on all the nodes in the data sharing system are consistent.

Each node in the data sharing system has a node identifier corresponding thereto, and each node in the data sharing system may store a node identifier of another node in the data sharing system, so that the generated block is broadcast to the other node in the data sharing system according to the node identifier of the other node in the following. Each node may maintain a node identifier list as shown in the following table, and store the node name and the node identifier in the node identifier list correspondingly. The node identifier may be an IP (Internet Protocol) address and any other information that can be used to identify the node, and table 1 only illustrates the IP address as an example.

TABLE 1

Node name	Node identification
		Node 1	117.114.151.174
Node 2	117.116.189.145
		…	…
Node N	119.123.789.258

Each node in the data sharing system stores one identical blockchain. The block chain is composed of a plurality of blocks, referring to fig. 3, the block chain is composed of a plurality of blocks, the starting block includes a block header and a block main body, the block header stores an input information characteristic value, a version number, a timestamp and a difficulty value, and the block main body stores input information; the next block of the starting block takes the starting block as a parent block, the next block also comprises a block head and a block main body, the block head stores the input information characteristic value of the current block, the block head characteristic value of the parent block, the version number, the timestamp and the difficulty value, and the like, so that the block data stored in each block in the block chain is associated with the block data stored in the parent block, and the safety of the input information in the block is ensured.

When each block in the block chain is generated, referring to fig. 4, when the node where the block chain is located receives the input information, the input information is verified, after the verification is completed, the input information is stored in the memory pool, and the hash tree for recording the input information is updated; and then, updating the updating time stamp to the time when the input information is received, trying different random numbers, and calculating the characteristic value for multiple times, so that the calculated characteristic value can meet the following formula:

SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+x))<TARGET

wherein, SHA256 is a characteristic value algorithm used for calculating a characteristic value; version is version information of the relevant block protocol in the block chain; prev _ hash is a block head characteristic value of a parent block of the current block; merkle _ root is a characteristic value of the input information; ntime is the update time of the update timestamp; nbits is the current difficulty, is a fixed value within a period of time, and is determined again after exceeding a fixed time period; x is a random number; TARGET is a feature threshold, which can be determined from nbits.

Therefore, when the random number meeting the formula is obtained through calculation, the information can be correspondingly stored, and the block head and the block main body are generated to obtain the current block. And then, the node where the block chain is located respectively sends the newly generated blocks to other nodes in the data sharing system where the newly generated blocks are located according to the node identifications of the other nodes in the data sharing system, the newly generated blocks are verified by the other nodes, and the newly generated blocks are added to the block chain stored in the newly generated blocks after the verification is completed.
