Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

The terms involved in the embodiments of the present application are explained as follows:

blockchain (Block chain): is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and the like. The blockchain is essentially a decentralised database, which is a series of data blocks generated by cryptographic methods, each data block containing a batch of information of network transactions 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 blockchain underlying platform may include processing modules for user management, basic services, smart contracts, operation monitoring, and the like. The user management module is responsible for identity information management of all blockchain participants, including maintenance of public and private key generation (account management), key management, maintenance of corresponding relation between the real identity of the user and the blockchain address (authority management) and the like, and under the condition of authorization, supervision and audit of transaction conditions of certain real identities, and provision of rule configuration (wind control audit) of risk control; the basic service module is deployed on all block chain node devices, is used for verifying the validity of a service request, recording the service request on a storage after the effective request is identified, for a new service request, the basic service firstly analyzes interface adaptation and authenticates the interface adaptation, encrypts service information (identification management) through an identification algorithm, and transmits the encrypted service information to a shared account book (network communication) in a complete and consistent manner, and records and stores the service information; the intelligent contract module is responsible for registering and issuing contracts, triggering contracts and executing contracts, a developer can define contract logic through a certain programming language, issue the contract logic to a blockchain (contract registering), invoke keys or other event triggering execution according to the logic of contract clauses to complete the contract logic, and simultaneously provide a function of registering contract upgrading; the operation monitoring module is mainly responsible for deployment in the product release process, modification of configuration, contract setting, cloud adaptation and visual output of real-time states in product operation, for example: alarms, monitoring network conditions, monitoring node device health status, etc.

The platform product service layer provides basic capabilities and implementation frameworks of typical applications, and developers can complete the blockchain implementation of business logic based on the basic capabilities and the characteristics of the superposition business. The application service layer provides the application service based on the block chain scheme to the business participants for use. For example, the various levels of credit platforms referred to in the present application may include a national credit platform, a municipal credit platform, a provincial credit platform, a county credit platform, a commission credit platform, a public utility credit platform, a public transportation service credit platform, and the like, where the various levels of credit platforms 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 clients provided by the credit platforms at all levels are used for providing execution entrance for users in the implementation process of credit joint rewards and punishments. 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, a user may submit a credit repair application via one client and perform a credit repair audit via another client.

Blockchains can be divided into private chains, alliance chains, and public chains; the federated chain is also referred to as a community blockchain (Consortium Block chains), which refers to a blockchain whose consensus process is controlled by preselected nodes. In a federated chain, all or part of the functions are only opened for node members within the chain, and each blockchain node in the federated chain can customize read-write permissions, query permissions, etc. based on needs. For example, in the credit combined reward and punishment system based on the blockchain, all levels of credit institutions in the country are node members which can be used as alliance chains, and the alliance chains open read-write rights, inquiry rights and the like for the node members.

Consensus mechanism (Consensus mechanism): is a mathematical algorithm for realizing trust establishment and rights acquisition among different nodes in a block chain system. In a blockchain system, the verification and confirmation of a transaction can be completed in a short time through voting of special nodes, and if a plurality of nodes with irrelevant interests can reach consensus for one transaction, all the nodes in the system can be considered to reach consensus for the same.

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

In 2016, china formally establishes a credit joint rewarding and punishing mechanism. The credit joint reward and punishment mechanism is divided into two parts, namely a joint credit incentive and a joint belief losing punishment ring, and relates to all sides in a social system; for example, it relates to traffic, business, tax, etc.; through government, market and social coordination, excitation and punishment are adopted, the trusted income and the trusted losing cost are improved, the trusted is enabled to be green light, and the trusted is limited everywhere. The excitation measures can comprise administrative approval of a green channel, acceptance of a declaration material, reduction of daily supervision frequency and the like; the punishment measures may include limiting the purchase of airline tickets, limiting the purchase of high-speed railway tickets, limiting the responsibility of enterprises, directors, supervision and advanced management, limiting the outbound, limiting financing credit, limiting the acquisition of government funds, implementing strict supervision of import and export goods clearance, closing or forbidding group chatting related to "swiping" and "frying" and closing off illegal "frying" enterprises, etc.

In order to realize the credit combined rewarding and punishing mechanism, a credit combined rewarding and punishing system is constructed, and the credit combined rewarding and punishing system is used as an implementation carrier of the credit combined rewarding and punishing mechanism and is provided with a multi-stage credit platform of China, province, city, county and the like. Because of the construction dispersion of the multi-stage credit platforms, the real-time synchronization of the credit information of individuals/enterprises in a credit joint rewarding and punishing system is poor, so that the credit information in each stage of credit platform is inconsistent; for example, credit repair is performed on individuals/enterprises, and layer-by-layer approval is required by credit institutions of cities, provinces and countries, so that the final approval result cannot be returned to the market-level credit platform in time. In addition, whether the credit combined rewards and punishment system is applied according to the national requirements in the process of business approval of each consignment office cannot be effectively supervised.

Therefore, the application provides a credit joint reward and punishment system based on the blockchain, which utilizes the decentralization of the blockchain to synchronize credit information in each node in the system, and solves the problem of inconsistent credit information in credit platforms at all levels. Referring to fig. 1, a node distribution diagram of a blockchain-based credit joint reward and punish system 100 according to an exemplary embodiment of the present application is shown, where nodes 120 of the blockchain-based credit joint reward and punish 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 credit platform, a municipal commission credit platform, a utility credit platform, and the like; establishing a blockchain based on the nodes 120; alternatively, the blockchain may include a coalition chain.

The node 120 provides credit joint rewards and punishments related services for various institutions 140 such as related departments, units, institutions and the like. For example, the public transportation service unit credit platform provides a credit inquiry window for transportation service departments such as aviation, railway and the like through the application program 160; the county region credit platform provides a credit inquiry window for the administrative service center of the county region and each street town through the application program 160; the market-level commission credit platform 160 provides credit joint rewards and punishments related services in business systems of institutions such as market operators, market food and drug monitoring, market environmental protection, and market tax; the utility 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 punishment portal, i.e., applet, through which credit joint punishment related services are provided by implanting applets in the system of each level of organization 140.

It should be noted that, the above-mentioned credit joint reward and punishment system 100 based on blockchain may be used as a data sharing system for data sharing between nodes, as shown in fig. 2, and based on fig. 1, the data sharing system is simply illustrated, where the data sharing system may include a plurality of nodes 201, and the plurality of nodes 201 may be respective clients in the data sharing system. Each node 201 may receive input information while operating normally and maintain shared data within the data sharing system based on the received input information. In order to ensure the information intercommunication in the data sharing system, information connection can exist between each node in the data sharing system, and the nodes can transmit information through the information connection. For example, when any 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 the shared data, so that the data stored on all nodes in the data sharing system are consistent.

Each node in the data sharing system has a node identifier corresponding to the node identifier, and each node in the data sharing system can store the node identifiers of other nodes in the data sharing system, so that the generated block can be broadcast to other nodes in the data sharing system according to the node identifiers of other nodes. Each node can maintain a node identification list shown in the following table, and the node names and the node identifications are correspondingly stored in the node identification list. The node identifier may be an IP (Internet Protocol, protocol of interconnection between networks) address, and any other information that can be used to identify the node, and the IP address is only illustrated in table 1.

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 and the same blockchain. The blockchain is composed of a plurality of blocks, referring to fig. 3, the blockchain is composed of a plurality of blocks, the starting block comprises a block head and a block main body, the block head stores an input information characteristic value, a version number, a time stamp 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 father 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 father 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 are associated with the block data stored in the father block, and the safety of the input information in the block is ensured.

When each block in the blockchain is generated, referring to fig. 4, when the node where the blockchain is located receives input information, checking the input information, after the checking is completed, storing the input information into a memory pool, and updating a hash tree used for recording the input information; then, updating the update time stamp to the time of receiving the input information, trying different random numbers, and calculating the characteristic value for a plurality of 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 eigenvalue algorithm used to calculate eigenvalues; version (version number) is version information of the related block protocol in the block chain; the prev_hash is the block header characteristic value of the parent block of the current block; the merkle_root is a characteristic value of input information; ntime is the update time of the update timestamp; the nbits is the current difficulty, is a fixed value in a period of time, and is determined again after exceeding a fixed period of time; x is a random number; TARGET is a eigenvalue threshold that can be determined from nbits.

Thus, when the random number meeting the formula is calculated, the information can be correspondingly stored to generate the block head and the block main body, and the current block is obtained. And then, the node where the blockchain is located sends the newly generated blocks to other nodes in the data sharing system where the newly generated blocks are located according to the node identification of other nodes in the data sharing system, the other nodes verify the newly generated blocks, and the newly generated blocks are added into the blockchain stored in the newly generated blocks after the verification is completed.
