Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings, the described embodiments should not be construed as limiting the present invention, and all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.

Before further detailed description of the embodiments of the present invention, terms and expressions mentioned in the embodiments of the present invention are explained, and the terms and expressions mentioned in the embodiments of the present invention are applied to the following explanations.

1) Transactions (transactions), equivalent to the computer term "Transaction," include operations that need to be committed to a blockchain network for execution and do not refer solely to transactions in the context of commerce, which embodiments of the present invention follow in view of the convention colloquially used in blockchain technology.

For example, a deployment (deployment) transaction is used to install a specified smart contract to a node in a blockchain network and is ready to be invoked; the Invoke (Invoke) transaction is used to append records of the transaction in the blockchain by invoking the smart contract and to perform operations on the state database of the blockchain, including update operations (including adding, deleting, and modifying key-value pairs in the state database) and query operations (i.e., querying key-value pairs in the state database).

2) A Block chain (Blockchain) is a storage structure for encrypted, chained transactions formed from blocks (blocks).

For example, the header of each block may include hash values of all transactions in the block, and also include hash values of all transactions in the previous block, so as to achieve tamper resistance and forgery resistance of the transactions in the block based on the hash values; newly generated transactions, after being filled into the tiles and passing through the consensus of nodes in the blockchain network, are appended to the end of the blockchain to form a chain growth.

3) A Blockchain Network (Blockchain Network) incorporates new blocks into a set of nodes of a Blockchain in a consensus manner.

4) Ledger (legger) is a general term for blockchains (also called Ledger data) and state databases synchronized with blockchains.

Wherein, the blockchain records the transaction in the form of a file in a file system; the state database records the transactions in the blockchain in the form of different types of Key (Key) Value pairs for supporting fast query of the transactions in the blockchain.

5) Intelligent Contracts (Smart Contracts), also known as chain codes (chaincodes) or application codes, are programs deployed in nodes of a blockchain network, and the nodes execute the intelligent Contracts called in received transactions to perform operations of updating or querying key-value data of the account database.

6) Consensus (Consensus), a process in a blockchain network, is used to agree on transactions in a block among a plurality of nodes involved, the agreed block is to be appended to the end of the blockchain, and the mechanisms for achieving Consensus include Proof of workload (PoW, Proof of Work), Proof of rights and interests (PoS, Proof of equity (DPoS), Proof of granted of shares (DPoS), Proof of Elapsed Time (PoET, Proof of Elapsed Time), and so on.

7) A user, for characterizing the business that requires the participation of multiple government entities, businesses and organizations, needs to submit individuals, legal persons or organizations (e.g., multiple governments, businesses, organizational departments, or possibly a cross over) of the blockchain over the relevant material.

8) The business unit is used for representing government units, enterprises (such as banks, and banks are required to open accounts when users transact business of companies), organizations (such as participating accounting firms, and the like) participating in business transaction of the users.

Referring to fig. 1, fig. 1 is a schematic usage environment diagram of a block chain network-based government affair information processing method according to an embodiment of the present invention, including a block chain network 200 (exemplarily shown to include a node 210-1 to a node 210-3), a block chain network management platform 300, a current institution node system 400 (exemplarily shown to include a terminal 600-1 belonging to the current institution node system 400 and a graphical interface 610-1 thereof), and a supervisor node system 500 (exemplarily shown to include a terminal 600-2 belonging to the supervisor node system 500 and a graphical interface 610-2 thereof), which are respectively described below.

The type of the blockchain network 200 is flexible and various, and may be any one of a public chain, a private chain, or a federation chain, for example. Taking a public link as an example, electronic devices such as user terminals and servers of any service entity can access the blockchain network 200 without authorization; taking a federation chain as an example, an electronic device (e.g., a terminal/server) under the jurisdiction of a service entity after obtaining authorization may access the blockchain network 200, and at this time, become a special type of node in the blockchain network 200, i.e., a client node.

Note that the client node may provide only functionality that supports the initiation of transactions by the business entity (e.g., for uplink storage of data or for querying of data on the chain), and may be implemented by default or selectively (e.g., depending on the specific business requirements of the business entity) for the functionality of the conventional (native) node 210 of the blockchain network 200, such as the ranking functionality, consensus services, ledger functionality, etc., described below. Therefore, the data and the service processing logic of the service subject can be migrated into the block chain network 200 to the maximum extent, and the credibility and traceability of the data and service processing process are realized through the block chain network 200.

The blockchain network 200 receives transactions submitted by client nodes (e.g., terminal 600-1 shown in fig. 1 as belonging to the current organization node system 400 and terminal 600-2 shown in fig. 1 as belonging to the supervisory organization node system 500) from different business entities (e.g., the current organization node system 400 and the supervisory organization node system 500 shown in fig. 1), performs the transactions to update or query the ledger, and displays various intermediate or final results of performing the transactions at user interfaces of the terminals (e.g., graphical interface 610-1 of terminal 600-1, graphical interface 610-2 of terminal 600-2). It is to be understood that, in the above, the blockchain network 200 receiving the transaction and executing the transaction specifically refers to the native node 210 in the blockchain network 200, and of course, when the client node of the service subject has the function (e.g., the consensus function, the ledger function) of the native node 210 in the blockchain network 200, the corresponding client node may also be included.

An exemplary application of the blockchain network is described below by taking an example that a plurality of service entities (different organization node systems) access the blockchain network to realize management of logistics data.

Referring to fig. 1, after obtaining authorization of the blockchain network management platform 300, a plurality of business entities involved in a logistics link, such as a current agency node system 400 and a supervision agency node system 500, a terminal 600-1 of the current agency node system 400 and a terminal 600-2 of the supervision agency node system 500 may access the blockchain network 200.

The service person of the current institution node system 400 logs in the current institution node system 400 in the graphic interface 610-1 of the terminal 600-1, inputs government affair information generated by the user in the current institution learning process, or a query request of a target user to be queried, wherein the query request is sent to the blockchain network management platform 300, the blockchain network management platform 300 generates a transaction corresponding to the update operation/query operation according to the received query request, the smart contract that needs to be invoked to implement the update/query operation, and the parameters passed to the smart contract are specified in the transaction, which also carries a digital signature signed by the current authority node system 400 (e.g., obtained by encrypting a digest of the transaction using a private key in a digital certificate of the current authority node system 400), and broadcasts the transaction to the blockchain network 200.

When a transaction is received in the node 210 in the block chain network 200, the digital signature carried by the transaction is verified, after the digital signature is successfully verified, whether the current organization node system 400 has the transaction right is determined according to the identity of the current organization node system 400 carried in the transaction, and the transaction fails due to verification judgment of any one of the digital signature and the right verification. After successful verification, node 210 signs its own digital signature (e.g., by encrypting the digest of the transaction using the private key of node 210-1) and continues to broadcast in blockchain network 200.

After the node 210 with the sorting function in the blockchain network 200 receives the transaction successfully verified, the transaction is filled into a new block and broadcasted to the node providing the consensus service in the blockchain network 200.

The node 210 providing the consensus service in the blockchain network 200 performs the consensus process on the new block to reach an agreement, the node 210 providing the ledger function appends the new block to the tail of the blockchain, and performs the transaction in the new block: for the transaction of submitting and updating the government information, updating the key value pair corresponding to the government information in the account book database; and for the transaction of inquiring and updating the government affair information, inquiring the key value pair corresponding to the government affair information from the account book database, and returning an inquiry result.

Similarly, a service person on the side of the supervision authority node system 500 may log in the supervision authority node system 500 in the graphical interface 610-2 of the terminal 600-2 (where the supervision authority node system may be configured with the highest authority to view government information uploaded by different authorities), input a government information query request, where the query request is sent to the blockchain network management platform 300, generate a transaction corresponding to the update operation/query operation by the blockchain network management platform 300 according to the received query request, specify in the transaction an intelligent contract that needs to be invoked to implement the update operation/query operation, and parameters passed to the intelligent contract, and the transaction also carries a digital signature signed by the current authority node system 400 (for example, obtained by encrypting a digest of the transaction using a private key in a digital certificate of the current authority node system 400), and broadcasts the transaction to the blockchain network 200. Further, it is understood that the type of data that nodes (service agents) of different organizations can query/update in the blockchain network 200 can be realized by restricting the authority of transactions that the service agents can initiate, for example, when the current organization node system 400 has the authority to initiate transactions for querying the target government information, a service person of the current organization node system 400 can input a target government information query request in the graphical interface 610-1 of the terminal 600-1 and generate a transaction for querying the target government information by the blockchain network management platform 300 to be broadcast to the blockchain network 200 to obtain the corresponding target government information from the blockchain network 200; when the supervisor node system 500 has the authority to initiate a transaction for inquiring government information, a service person on the side of the supervisor node system 500 may input a request for inquiring government information in the graphical interface 610-2 of the terminal 600-2, and generate a transaction broadcast for inquiring government information by the blockchain network management platform 300 into the blockchain network 200 to obtain corresponding government information from the blockchain network 200. Meanwhile, the supervision organization node system 500 may further store an original record of government affair information, and may verify the government affair information input by the target user, for example: corresponding identity card information, tax registration card information and legal testimony information in the government affair information are processed.

An exemplary functional architecture of a block chain network provided in an embodiment of the present invention is described below, referring to fig. 2, fig. 2 is a functional architecture schematic diagram of a block chain network 200 provided in an embodiment of the present invention, which includes an application layer 201, a consensus layer 202, a network layer 203, a data layer 204, and a resource layer 205, which are described below respectively.

The resource layer 205 encapsulates computing, storage, and communication resources that implement each node 210 in the blockchain network 200, such as computing, storage, and communication resources in computers, servers/clusters, and clouds, abstracts and provides a uniform interface to the data layer 204 to shield the underlying hardware implementing the resource layer 205 from differences.

The computing resources include various forms of processors such as a Central Processing Unit (CPU), an Application Specific Integrated Circuit (ASIC), and a Field-Programmable Gate Array (FPGA).

The storage resources include various types of storage media such as various volatile memories and nonvolatile memories. The nonvolatile Memory may be a Read Only Memory (ROM) or a Programmable Read-Only Memory (PROM). Volatile Memory can be Random Access Memory (RAM), which acts as external cache Memory.

The communication resources include various links for communication between nodes 210 of the blockchain network, between the blockchain network 200 and the traffic master.

The data layer 204 encapsulates various data structures that implement the ledger, including blockchains implemented in files in a file system, state databases of the key-value type, and presence certificates (e.g., hash trees of transactions in blocks).

The network layer 203 encapsulates the functions of a Point-to-Point (P2P) network protocol, a data propagation mechanism and a data verification mechanism, an access authentication mechanism and service agent identity management.

Wherein the P2P network protocol implements communication between nodes 210 in the blockchain network 200, the data propagation mechanism ensures propagation of transactions in the blockchain network 200, and the data verification mechanism implements reliability of data transmission between nodes 210 based on cryptography methods (e.g., digital certificates, digital signatures, public/private key pairs); the access authentication mechanism is used for authenticating the identity of the service subject added into the block chain network 200 according to an actual service scene, and endowing the service subject with the authority of accessing the block chain network 200 when the authentication is passed; the business entity identity management is used to store the identity of the business entity that is allowed to access blockchain network 200, as well as the permissions (e.g., the types of transactions that can be initiated).

The consensus layer 202 encapsulates the functions of the mechanism for the nodes 210 in the blockchain network 200 to agree on a block (i.e., a consensus mechanism), transaction management, and ledger management.

The consensus mechanism comprises consensus algorithms such as POS, POW and DPOS, and the pluggable consensus algorithm is supported.

The transaction management is configured to verify a digital signature carried in the transaction received by the node 210, verify identity information of the service entity, and determine whether the node has an authority to perform the transaction (read related information from the identity management of the service entity) according to the identity information; for the service agents authorized to access the blockchain network 200, the service agents all have digital certificates issued by the certificate authority, and the service agents sign the submitted transactions by using private keys in the digital certificates of the service agents, so that the legal identities of the service agents are declared.

Account book management: for maintaining block chains and ledger databases. For the block with the consensus, adding the block to the tail of the block chain; and executing the transaction in the block which obtains the consensus, updating the key-value pairs in the state database when the transaction comprises an updating operation, inquiring the key-value pairs in the account book database when the transaction comprises an inquiring operation, and returning an inquiring result to the business body. The method supports query operations of multiple dimensions of the account book database, and comprises the following steps: querying the chunk based on the chunk sequence number (e.g., hash value of the transaction); inquiring the block according to the block hash value; inquiring a block according to the transaction serial number; inquiring the transaction according to the transaction serial number; inquiring account data of a business main body according to an account (serial number) of the business main body; and inquiring the block chain in the channel according to the channel name.

The application layer 201 encapsulates various services that the blockchain network can implement, including tracing, crediting, and verifying transactions.

In some embodiments of the present invention, when other organization nodes in the blockchain network need to query the government affair information of the corresponding target user in the blockchain network, with reference to the method for processing the government affair information of the target user in the blockchain network shown in fig. 5, continuing to refer to fig. 6, where fig. 6 is an optional flowchart of the method for processing the government affair information of the target user in the blockchain network according to the embodiment of the present invention, and a processing procedure includes the following steps:

step 4101: acquiring a private key of a target node matched with the authority information of the government affair information;

step 4102: and judging whether the dynamic password needs to be acquired or not, if so, executing a step 4104, and otherwise, executing a step 4103.

Further, when a corresponding dynamic password is requested from the target user corresponding to the target user identifier, the target user can timely know when the government affair information of the target user is viewed by corresponding other organization nodes (government departments), so as to timely contact with the other organization nodes (government departments).

Referring to fig. 7, fig. 7 is an optional flowchart of the method for processing government affairs information of the target user in the blockchain network according to the embodiment of the present invention, and it can be understood that the steps shown in fig. 7 may be executed by various electronic devices operating the information processing apparatus, for example, a dedicated terminal, a server, or a server cluster with a government affair information processing function of the target user. The following is a description of the steps shown in fig. 7.

Step 701: and acquiring different processing results of the government affair information of the target user in the block chain network.

The processing of the government information may be implemented based on a corresponding intelligent contract, wherein the intelligent contract may store data that may be used to record information, facts, associations, balances, and any other information needed to implement the contract execution logic. An intelligent contract may be described as a computer-executable program consisting of functions, where an instance (instance) of the intelligent contract may be created, and the functions are called to execute the logic of the intelligent contract.

In some embodiments of the invention, smart contracts may be implemented based on objects and object-oriented classes. For example, the terms and components of a smart contract may be represented as objects that are processed by an application that implements the smart contract. An intelligent contract (or an object in an intelligent contract) may invoke another intelligent contract (or an object in the same intelligent contract) like other object-oriented objects. For example, the call made by an object may be a call to create, update, delete, propagate, or communicate with an object of another class. Calls between objects may be implemented by functions, methods, Application Programming Interfaces (API) or other calling mechanisms. For example, a first object may call a function to create a second object.

In some embodiments of the present invention, the identifier of the target user may be obtained by a node device of the blockchain invoking an intelligent contract deployed in the blockchain network, where the intelligent contract declares that a corresponding target user identifier is generated based on the target user. And determining the government affair information of the corresponding target user through the target user identification.

Step 702: and triggering to broadcast in the block chain network in response to the processing result of the government affair information.

Therefore, data synchronization among other mechanism nodes in the block chain network can be realized, and the processing result matched with the government affair information of the target user can be updated.

Step 703: and pushing the processing result of the government affair information of the target user to a corresponding client.

Through the technical scheme shown in this embodiment, when the government affair information of the target user is processed by the corresponding organization node, the processed result is stored in the block chain network, because of the P2P network system with the distributed data storage structure, which is achieved by each node in the block chain network through a consensus mechanism, the data in the block chain is distributed in one "block" which is connected in time, the latter block contains the data summary of the former block, and according to the difference of specific consensus mechanisms (such as POW, POS, DPOS, PBFT, etc.), full backup of data of all or part of nodes is achieved. As is well known to those skilled in the art, since the blockchain network system operates under a corresponding consensus mechanism, data that has been recorded in the blockchain database is difficult to be tampered with by any node, for example, a blockchain with Pow consensus is adopted, and it is possible to tamper with existing data only by an attack that requires at least 51% of effort over the entire network, so the blockchain system has characteristics of ensuring data security and preventing tampering against attacks, which are incomparable with other centralized database systems. Therefore, the data recorded in the distributed database of the blockchain cannot be attacked or tampered, so that the real reliability of the processing result of the distributed database of the blockchain is guaranteed, and the change of the processing result is avoided.

The following proceeds to describe the method for processing government affairs information based on the blockchain network, where, referring to fig. 8, fig. 8 is a schematic usage environment diagram of the method for processing government affairs information based on the blockchain network, where,

After the node unit passes the audit, the node unit triggers and informs other service related units through the service scheduling center.

The service collaboration center is used for configuring specific processes for certain service transaction and corresponding information of related participating units, after the user uploads information required by the service, the user selects transaction content, and triggers the service collaboration center to select different service processes and participating unit nodes.

After the data of the user is audited by one service unit, all the units left in the block chain network can simultaneously acquire the shared information of the user from the block chain network, complete data synchronization and audit the service, so that the processing efficiency of government service is accelerated and improved.

Meanwhile, the audit results of each unit can be respectively returned to the user (for example, a task that can be completed after the single unit node finishes the audit), or can be returned after being aggregated. (e.g., auditing of legal texts requires multi-node parameter completion). In this process, the processing of government information may be implemented based on corresponding intelligent contracts, wherein the intelligent contracts may store data that may be used to record information, facts, associations, balances, and any other information needed to implement the contract execution logic. An intelligent contract may be described as a computer-executable program consisting of functions, where an instance (instance) of the intelligent contract may be created, and the functions are called to execute the logic of the intelligent contract.

In some embodiments of the invention, smart contracts may be implemented based on objects and object-oriented classes. For example, the terms and components of a smart contract may be represented as objects that are processed by an application that implements the smart contract. An intelligent contract (or an object in an intelligent contract) may invoke another intelligent contract (or an object in the same intelligent contract) like other object-oriented objects. For example, the call made by an object may be a call to create, update, delete, propagate, or communicate with an object of another class. Calls between objects may be implemented by functions, methods, Application Programming Interfaces (APIs), or other call mechanisms. For example, a first object may call a function to create a second object.

Further, based on the above description about the smart contract, the rentable status data of the target rental object according to one or more embodiments provided in the present specification may also be stored in a "status database" of the block chain, for example, in the content of "store" of the smart contract account, or in a receipt (Receipts) tree corresponding to the execution smart contract, and the rentable status of the target rental object is maintained by the smart contract management to perform addition, deletion, check, and modification of the rentable status data of the target rental object. Those skilled in the art will appreciate that the "storage" content of the intelligent contract account may be stored in the form of an MPT tree in a "state tree" of the contract account, which is stored in the local database of each node device of the blockchain as the content of the "state database" in the distributed database of the blockchain.
