Detailed Description

For reference or clarity, related art terms, abbreviations or nouns related to the embodiments of the present application are first explained as follows:

And (3) straddling a chain: it is a technique that allows direct circulation of value across the chain and the obstacle between chains. Among the problems faced by blockchains, the interoperability between blockchains greatly limits the application space of the blockchains, and the cross-chain technology is a key for realizing value Internet for public chains or private chains, is connected with scattered blockchain islands and is a bridge for outward expansion and connection of the blockchains.

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The embodiment of the application discloses a method, a device and a system for realizing business services of a cross-region block chain, which can be applied to a series of business service scenes related to electric energy metering but are not limited to. The method mainly adopts a cross-chain technology to realize the cross-chain to the chain of custody of the enterprise chain, carries out up-chain certification on key data of a business link in the chain of custody, realizes trusted business service under the supervision of the chain of custody based on certification data, provides a series of trusted service such as up-chain data inquiry of business data such as energy metering and the like and required business transaction and the like for users, and improves the credibility of the social public on the business data and the business service.

Correspondingly, the method for realizing the business service of the cross-block chain can be applied to the supervision chain end and the enterprise chain end, and is divided into a method for realizing the business service of the cross-block chain applied to the supervision chain end and a method for realizing the business service of the cross-block chain applied to the enterprise chain end.

Referring to fig. 1, a flow chart of a method for implementing a service of a cross-blockchain applied to a supervision chain end is provided, and the method comprises the following processing steps:

step 101, obtaining a cross-link transaction proposal, wherein the cross-link transaction proposal is a transaction proposal which is initiated by an enterprise chain end in response to a cross-link transaction request initiated by an obtaining client and corresponds to the cross-link transaction request.

The embodiment of the application mainly takes the related business service scene of electric energy metering as an example for description, and correspondingly, the enterprise chain and the supervision chain can be respectively a power enterprise chain and a government affair supervision chain for supervising the related business of the power enterprise chain, but the application is not limited to the power enterprise chain and the government affair supervision chain, and can be adaptively transformed according to scene requirements in practical application.

The enterprise chain end is deployed with an enterprise chain and an enterprise chain contract so as to realize the uplink of data (such as traceability records of business data) of the enterprise chain and the related processing based on the uplink data based on the enterprise chain contract, and the supervision chain end is deployed with a supervision chain and a supervision chain contract so as to realize the uplink of data (such as stored data) of the supervision chain and the related processing based on the uplink data based on the supervision chain contract.

Optionally, the enterprise link end and the supervision link end are respectively associated with a corresponding trusted hardware node, and the trusted hardware node of the enterprise link end and the trusted hardware node of the supervision link end interact through a relay link contract. The trusted hardware node is a functional node provided based on the trusted hardware, and the trusted hardware can be understood as a box, and can only be read externally in the running process, and when the authority owners write data (such as program code data of software) from the outside, the non-authority owners cannot change the data.

Alternatively, the present application employs the SGX (Software Guard Extensions) technology of intel processor and applies the SGX technology on the gateway node to propose the trusted hardware of "gateway node-trusted hardware mode". The SGX is a set of instructions that is used in this embodiment to enhance the security of application code and data, providing them with greater protection against leakage or modification. The gateway node-trusted hardware mode passes through remote authentication, so that the published application program realized based on SGX technology can be verified to normally run on a trusted hardware platform, and the software is ensured not to be tampered. Thus, it is believed that the SGX application will execute in the correct cross-chain process as if it were a contract.

Based on trusted hardware nodes respectively associated with the enterprise chain end and the supervision chain end (e.g., the power enterprise chain and the government chain), this step 101 may be further implemented as:

11 Obtaining a cross-link transaction proposal submitted by a trusted hardware node at the end of an enterprise by utilizing the relay link contract, and verifying cross-link transaction data in the cross-link transaction proposal;

when a client initiates a cross-link transaction request, an enterprise link contract obtains the cross-link transaction request initiated by the client, and meanwhile, a trusted hardware node at the end of the enterprise link monitors the cross-link transaction request and submits a cross-link transaction proposal corresponding to the cross-link transaction request to a relay link contract after verification of the cross-link transaction request. The relay link contract correspondingly obtains a cross-link transaction proposal submitted by a trusted hardware node at the end of the enterprise link, and verifies cross-link transaction data in the cross-link transaction proposal.

12 The trusted hardware node of the chain of supervision is utilized to synchronize the cross-chain transaction data verified by the relay chain contract, and after the cross-chain transaction data passes the transaction verification of the relay chain, a signature cross-chain transaction proposal is constructed, and the signature cross-chain transaction proposal is submitted to the chain of supervision contract.

Step 102, supervising the cross-chain transaction proposal based on the certification data.

The method comprises the steps of carrying out uplink processing on business data generated by an enterprise business platform in advance in an enterprise chain, and carrying out authentication and verification on the uplink data in the enterprise chain in advance at a monitoring chain end, namely carrying out uplink processing on the business data generated by the enterprise business platform in advance in the enterprise chain and carrying out authentication and verification on the uplink data in the enterprise chain at the monitoring chain end.

Taking the related business service scenario of electric energy metering as an example, the enterprise business platform can be an original electric power production metering and scheduling platform.

Taking the related business service scenario of electric energy/electric power metering as an example, the business data includes, but is not limited to, electric energy/electric power metering data, and the cross-chain transaction request may be a query request for the electric energy/electric power metering data or a transfer request based on the electric energy/electric power metering data (such as a transfer request when electric charge is paid).

The application particularly provides and builds a data tracing model to ensure that the data tracing from an enterprise chain (such as a power enterprise chain) to a supervision chain (such as a government supervision chain) is safe and reliable. Based on the proposed data traceability model, the business data generated by the enterprise business platform is processed in the enterprise chain, and the uplink data in the enterprise chain is authenticated and stored at the monitoring chain end, and the process can be further realized as follows:

Generating a corresponding tracing record based on the description of the predetermined data tracing model for the business data; the tracing records are uplink to an enterprise chain; authenticating service data corresponding to the traceability record at a supervision chain end, and performing uplink certification on an authentication result at the supervision chain end; the certification data comprises corresponding relation information of the authentication result and the tracing record identification.

The model structure of the proposed and constructed data traceability model comprises types and relations, wherein the types comprise entities, agents and activities; the entity is used for describing the object needing tracing; the agent is used for describing the creator or editor of the data; an activity is used to describe operations that occur or act on an entity to indicate that the entity is the operation upon which the current state and/or change in attributes of the entity is based; relationships are used to express interrelationships between entities, agents, activities.

The data tracing model is described in further detail below.

The data tracing model may be, but is not limited to, a ProvChian-based data tracing model.

In the present application, the purpose of the ProvChian-based data traceability model is to convert domain ("domain" is understood to be a specific environment) or application-specific traceability representation into such a generic model, so that transfer or exchange can be made between systems. Thus, the heterogeneous system can export local trace sources to the core data model, and then applications that need to understand the trace sources can import, process, and reason about the model. The user can perform standardized description of the traceable data through a wide format such as RDF (resource description framework), XML (extensible markup language), JSON (JavaScriptObjectNation), and the like, so as to facilitate further operation and management.

The ProvChian-based data traceability model provided by the application comprises two main components: types and relationships. Referring to the ProvChain-based data tracing architecture shown in FIG. 2, the type may be Entity (Activity), activity or Agent (Agent). An entity is a description of what it is to record its traceability information, including electronic objects such as files or web pages, and physical objects such as books, vehicles, and abstract concepts. Activity is used to refer to some form of operation that occurs or acts upon an entity to describe how the entity becomes current and how the attributes of the entity change, including the creation, transformation, or modification of the entity, etc. Just as entities cover a wide range of concepts, the concept of activity is also wide, for example: the information processing activity may include copying, moving, and the physical activity may include a number of processes through which the book is printed to sell. An activity may generate a new entity, taking a document entity as an example, modifying the document may generate new text, which may be represented by wasgeneddy; an activity may also be represented by an entity, in terms of used. An agent assumes some form of responsibility for the presence of one entity, the occurrence of an activity, or the activity of another agent, which may be a person, software, or other entity that may be given a role of responsibility. When an agent is responsible for an activity, the Provchain data model represents that the agent is related to the activity by wasassiated with, and that the entity belongs to an agent by wasassibutedto. One or more attributes of an entity may change between versions, each new version being a new entity, wasDerivedFrom representing a derivative relationship.

The application adopts the blockchain technology to store the traceability record based on the description of the data traceability model so as to ensure the tamper-proof of the traceability record and realize the trusted storage and the trusted traceability. The application aims to establish a set of complete technical specifications for the research of the ProvChain-based data tracing architecture, so that the whole process from acquisition, storage and query of tracing data follows a unified standard, and tracing can be realized even among heterogeneous data systems. The method determines what content the trace data should contain and the trace data storage mode, and has important effect on the realization of data trace.

Based on the definition of the core structure of the data tracing model, the tracing object to be described in the application is called an entity, and the activity is an operation (such as copying, modifying, etc. the data) performed on the entity in a period of time, and the agent is defined as a creator or editor of the data. The representation of the trace information in the data trace source model is mainly represented by trace metadata, wherein the metadata of the trace source data model is specifically represented as a tuple, the object to be traced is described based on the tuple, and the operation performed on the trace object and the information of the user (creator/editor), namely trace records, can be represented as (data entity, operation performed on the data, user name). This ensures that the data meets open standards that make this information provable and help facilitate further interaction with different users.

Taking a related business service scenario of electric energy metering as an example, the application converts tracking data (defined as td) required by realizing traceability (such as traceability related in related query service of electric energy metering) in the scenario into traceability data (traceability record) based on model description so as to represent causal relationship and dependency relationship among entities. In the process of tracking data conversion, specifically, related data objects (such as related parameter data objects related to power metering and may be data objects based on file description) in a power enterprise chain and a government administration chain are taken as entities, a system user is taken as an agent, an activity is an operation performed on the chain, and trace metadata TSR (Trace source record) may be expressed as:

TSR＝(en,pr,act)

where en represents an entity, pr represents an agent, act represents an activity, the entity is made up of several parts, which may include, but are not limited to, converted file name, category, format and data, namely:

en＝(filename,class,type,data)

the agent includes an agent type and name, namely:

pr＝(pr _type ,pr _name )

the activity includes a data object, an activity agent, the type of operation performed on the data object, and an activity timestamp, i.e.:

act＝(act _object ,act _pr ,act _type ,timestamp)

then:

TSR＝((filename,class,type,data),(pr _type ,pr _name ),

(act _object ,act _pr ,act _type ,timestamp))

wherein the entity has the following relationship with the activity:

(act _object ,act _pr ,act _type ,timestamp)→used→(filename,class,type,data)(filename,class,type,data)→wasGeneratedBy→(act _object ,act _pr ,act _type ,timestamp)

the activity has the following relationship with the agent:

(act _object ,act _pr ,act _type ,timestamp)→wasAssociatedWith→(pr _type ,pr _name )

The following relationship exists between the entity and the agent:

(filename,class,type,data)→wasAtrributedTo→(pr _type ,pr _name )

also, there is the following internal relationship:

(filename ₂ ,class ₂ ,type ₂ ,data ₂ )→wasDerivedFrom→(filename ₁ ,class ₁ ,type ₁ ,data ₁ )(act _object2 ,act _pr2 ,act _type2 ,timestamp ₂ )→wasInformedBy→(act _object1 ,act _pr1 ,act _type1 ,timestamp ₁ )

(pr _type2 ,pr _name2 )→actedOnBehalfOf→(pr _type1 ,pr _name1 )

wasInformadBy represents a previous entity such as (act _object2 ，act _pr2 ，act _type2 ，timestamp ₂ ) By the latter entity, e.g. (act _object1 ，act _pr1 ，act _type1 ，timestamp ₁ ) The latter entity is generated and used.

actedOnBehalfOf represents the former as (pr _type2 ，pr _name2 ) For the latter as (pr) _type1 ，pr _name1 ) Responsible for, in particular, a certain partyThe equation is responsible for the activity that occurs.

Other parties to the data tracing (e.g., operators of the power enterprise chain and government chain, system users, etc.) may also perform operations on the data such as augmentation, but operations on the data must be recorded on the blockchain for future verification, thus forming the tracing chain. The trace-source chain shown in fig. 3 may specifically implement recording the operations involved on the blockchain based on the association between the entities (0, 0'), the activities (E1, E2), and the agents (A1, A2).

With the continuous growth of the chain, all data is permanently stored in the blockchain after being verified and cannot be tampered, so that the integrity of the traceable data is ensured, and the traceability is convenient.

In response to obtaining the cross-chain transaction proposal, the supervising chain end supervises the cross-chain transaction proposal based on the certification data. The embodiment specifically provides a cross-chain supervision technology based on hash anchoring, and the preset hash anchoring rule provided by the technology at the end of a supervision chain is used for supervising the obtained cross-chain transaction proposal based on the certification data.

The hash anchoring-based cross-chain supervision technique is described as follows:

hash anchoring refers to the fact that during a certain time, both parties to a transaction agree on a hash value H, if the original image R is provided such that:

Hash(R)＝H

the transaction is valid and otherwise it is invalidated. If the transaction is unsuccessful for various reasons, the hash anchor can enable the transaction participants to take back own transaction data (such as the amount of the electric charge transfer), so as to realize the supervision of the actions of the transaction participants and avoid the loss caused by fraud or transaction failure.

In the application, an intelligent contract corresponding to a corresponding Hash anchoring rule (namely the preset Hash anchoring rule) is formulated based on the technology, two transaction parties (namely a user A and a user B (namely a payment party and a charging party during electric charge transfer) can lock data of each other through the intelligent contract (A is locked firstly and B is locked again), and the intelligent contract realizes the following logic or provides the following rules:

21 User a uses the username ID _A Login password P _A Timestamp T _A And a random number sigma, generating a real-time original image R;

22 If anyone can provide a random value R' to the smart contract within the first time period, such that the contract verifies that the following relationship holds:

Hash (R ')= H (when R' equals R)

The data of the user B is automatically transferred to the user a, otherwise, the data is sent to the user B after timeout.

Illustratively, the first duration is t minutes/hour.

23 If anyone issues the original password R to the smart contract for a second period of time, the data of a will be automatically forwarded to B, otherwise it is forwarded to a.

The second time period is longer than the first time period, and is illustratively 2t minutes/hour.

The rule is mainly formulated for A, wherein A is data of B, random passwords generated by the A are required to be provided for an intelligent contract before overtime, and after the contract passes verification, the asset of B is transferred to A. This transaction is successful, and at the same time, the original password R provided by a is also broadcast publicly and recorded on the blockchain. At this point, B can issue the smart contract with the public password R, and according to the third rule, 23, it is possible to obtain data that a locks in the smart contract, and theoretically B has (second duration-first duration) time (e.g., time t to 2t hours) to complete the operation (depending on how fast a can complete his operation).

For the obtained cross-chain transaction request, the supervision chain end determines whether the tracing record requested by the cross-chain transaction request is a legal tracing record after authentication according to the authentication data (the authentication data comprises the corresponding relation information of the authentication result and the tracing record identification), if so, further combines the hash anchoring rule of the logic indication to supervise both transaction sides of the cross-chain transaction request so as to supervise the behaviors of both transaction sides and avoid the loss caused by fraud or transaction failure.

Step 103, in response to the cross-chain transaction proposal, tracing service data required by the cross-chain transaction proposal from an enterprise chain and an enterprise service platform through supervision, and executing corresponding transactions based on the service data obtained through tracing.

Specifically, if the cross-chain transaction proposal passes the supervision of the supervision chain end, the supervision chain end inquires the target traceability record corresponding to the cross-chain transaction proposal from the enterprise chain, and inquires the original business data corresponding to the cross-chain transaction proposal from the enterprise business platform according to the target traceability record.

The target tracing record is described based on a defined data tracing model, so that the required original business data can be traced from enterprise business platforms such as an original power production metering and scheduling platform according to various description information (such as various metadata information) of the data tracing model in the target tracing record, corresponding transaction is executed based on the original business data obtained by tracing, such as transfer transaction execution, or result encapsulation and the like is carried out on the data obtained by tracing during electric energy metering data query.

Step 104, transmitting corresponding transaction feedback information to the enterprise link end in a cross-link manner so as to return the transaction feedback information to the client through the enterprise link end.

And then, the supervision chain end transmits corresponding transaction feedback information, such as whether the transfer is successful or not, account balance after the transfer, or related information of electric quantity metering during electric quantity inquiry, and the like, to the enterprise chain end based on the cross-chain technology, and returns the transaction feedback information to the user client end through the enterprise chain end.

In practical application, the method can be used for enhancing the safety and reliability of the whole life cycle of metering data by utilizing the characteristics of distributed storage, non-falsification, disclosure transparency and the like based on a blockchain technology, completing the statistical query analysis of uplink data by combining a cross-chain technology, carrying out query and check service on service data such as power metering and other service data and electronic certificate storage and check of an internal user and an external user, and can be used for checking based on a third party institution trusted endorsement, thereby improving the transparency and the credibility of metering asset/verification data and electric energy meter quality supervision and evaluation on the public and social public.

According to the scheme, the method of the embodiment of the application obtains the cross-chain transaction proposal at the monitoring chain end, the cross-chain transaction proposal is a transaction proposal corresponding to the cross-chain transaction request initiated by the enterprise chain end in response to obtaining the cross-chain transaction request initiated by the client, the monitoring chain end monitors the cross-chain transaction proposal based on the certification data (wherein, the business data generated by the enterprise business platform completes the uplink processing in the enterprise chain in advance, the uplink data in the enterprise chain completes the certification in the monitoring chain end in advance), the business data required by the cross-chain transaction proposal is traced from the enterprise chain and the enterprise business platform through the monitoring in response to the cross-chain transaction proposal, the corresponding transaction is executed based on the business data obtained by tracing, and the final supervision chain end transmits the corresponding transaction feedback information to the enterprise chain end in a cross-chain manner so as to return the transaction feedback information to the client through the enterprise chain end. Therefore, by applying the scheme of the application, the enterprise chain can be cross-linked to the chain of custody, thousands of data can be timely authenticated in a cross-link mode based on a cross-link technology, the timeliness and the credibility of the data are ensured, and the required business data such as key data of each link of electric quantity metering and the like are ensured to be real and effective by calling the uplink evidence-storing service, so that the traceability query capability of the uplink credible data is provided for a user on the basis.

Referring to fig. 4, a flow chart of a method for implementing service of a cross-block chain applied to a service link end is provided, and the method for implementing service of a cross-block chain applied to a service link end includes the following processing steps:

step 401, obtaining a cross-link transaction request initiated by a client.

Taking the related business service scenario of electric energy/electric power metering as an example, when the client side has the inquiry requirement on the electric energy/electric power metering data or the transfer requirement (such as the transfer requirement when electric charge is paid) based on the electric energy/electric power metering data, a corresponding inquiry request on the electric energy/electric power metering data or the transfer request (such as the transfer request when electric charge is paid) based on the electric energy/electric power metering data can be initiated to the enterprise chain end, and the enterprise chain end correspondingly obtains the cross-chain transaction request initiated by the client side.

Further, the enterprise chain end can specifically obtain the cross-chain transaction request initiated by the client by using a preset enterprise chain contract.

And step 402, initiating a cross-chain transaction proposal corresponding to the cross-chain transaction request to a supervision chain end so that the supervision chain end supervises the cross-chain transaction proposal based on the certification data, tracing service data required by the cross-chain transaction proposal from an enterprise chain and an enterprise service platform through supervision in response to the cross-chain transaction proposal, and executing corresponding transaction based on the service data obtained through tracing.

The enterprise chain end and the supervision chain end are respectively associated with corresponding trusted hardware nodes, and the trusted hardware nodes of the enterprise chain end and the trusted hardware nodes of the supervision chain end interact through a relay chain contract.

When the enterprise chain end obtains a cross-link transaction request initiated by a client by utilizing a preset enterprise chain contract, the enterprise chain end monitors the cross-link transaction request of the client by utilizing a trusted hardware node of the enterprise chain end, and when the hardware node monitors the cross-link transaction request obtained by the enterprise chain contract, the cross-link transaction request is verified, and after the cross-link transaction request is verified, the cross-link transaction proposal corresponding to the cross-link transaction request is further submitted to the relay chain contract, so that the cross-link transaction proposal corresponding to the cross-link transaction request is initiated to the supervision chain end through the relay chain contract.

Illustratively, the trusted hardware node at the end of the power enterprise may perform SPV simple payment verification on the monitored cross-chain transaction request, and may collect block header, SPV (Simplified Payment Verification, simple payment verification) information, etc. after passing the verification, then generate a cross-chain transaction proposal corresponding to the cross-chain transaction request based on the collected information, and submit the cross-chain transaction proposal corresponding to the cross-chain transaction request to the relay chain contract.

After the relay link contract obtains the cross-link transaction proposal submitted by the trusted hardware node of the enterprise chain end, the cross-link transaction data in the cross-link transaction proposal is verified, then the trusted hardware node of the supervision chain end synchronizes the cross-link transaction data verified through the relay link contract, and after the transaction verification of the relay chain is performed, a signature cross-link transaction proposal is constructed, and the signature cross-link transaction proposal is submitted to the supervision chain contract, so that the initiation of the cross-link transaction proposal to the supervision chain end is realized.

On the basis, the supervision chain end supervises the cross-chain transaction proposal based on the certification data, and responds to the cross-chain transaction proposal to trace the business data required by the cross-chain transaction proposal from the enterprise chain and the enterprise business platform through supervision, and executes corresponding transaction based on the business data obtained through tracing.

Specifically, for the obtained cross-link transaction request, the supervision chain end determines whether the tracing record requested by the cross-link transaction request is a legal tracing record authenticated according to the certification data (the certification data comprises the corresponding relation information of the certification result and the tracing record identifier), if so, further combines the hash anchoring rule of the logic indicator to supervise both transaction sides of the cross-link transaction request so as to supervise the behaviors of both transaction sides and avoid the loss caused by fraud or transaction failure.

And if the cross-chain transaction proposal passes the supervision of the supervision chain end, the supervision chain end inquires a target traceability record corresponding to the cross-chain transaction proposal from the enterprise chain, and inquires the original business data corresponding to the cross-chain transaction proposal from the enterprise business platform according to the target traceability record.

Step 403, obtaining transaction feedback information transmitted by the chain of custody end in a cross-chain manner, and returning the transaction feedback information to the client.

And the enterprise chain end correspondingly acquires transaction feedback information transmitted by the chain of supervision end in a cross-chain manner and returns the transaction feedback information to the client for a client user to check.
