Referring to fig. 2, a first embodiment of the present application provides a flowchart of a data processing method. In this embodiment, the data processing method includes the steps of:
step S10, if a service request is received, analyzing a target sub-chain identifier in the service request;
at present, due to the factors of single machine resource, network bandwidth, distributed consensus consumption and the like, a single block chain has a performance bottleneck and cannot support increasingly higher uplink demands of more and more applications; in addition, the account book on the same blockchain is readable for all nodes, and the privacy protection scheme also has problems. In order to solve single-chain performance bottleneck and service isolation privacy requirements, medium-currency credit card industry development limited companies propose a Brochain multi-chain enterprise-level permission chain architecture, and adopt a combination of 'main account book-partition account book', namely, each partition account book generates respective page data firstly, and then submits page data hash (hash function, also called hash function) to the main account book, and after the main account book collects the page data hash of all partition account books, final block data is generated. After the hierarchical data structure formed by the tree and the linked list together is adopted, the characteristic that data in the block chain cannot be tampered can still be guaranteed, once data of any partition account book is illegally modified, the hash of the page data of the modified partition account book is inconsistent, and finally the hash of the block data where the page is located is inconsistent, so that all the partition account books cannot be tampered as long as the main account book is owned. However, rather than handing transactions to different nodes for processing, the transaction is handed to a consensus node, which assigns transactions from different partitions to different processes for parallel execution. Therefore, the transaction on the blockchain is uniformly verified and recorded in the account book by the consensus node and then distributed to the witness node for witness, so that the business account book is isolated only for the witness node, and the consensus node can still check all account book data, and the scheme comprises the following steps: 1. the consensus node can check all account book data, and the business account book isolation only aims at the witness nodes; 2. the performance bottleneck depends on the consensus node, and the resource limitation of a single server cannot be eliminated; 3. the application of the main account book cannot be migrated to the partition account book and other problems, so that the privacy isolation effect of the current user is poor when the block chain is applied. On the basis, the data processing method is provided, the access operation of the service request is routed to the corresponding target sub-chain according to the target sub-chain identifier in the service request, and the information in the target sub-chain cannot be checked by the parent chain common identification node, so that service isolation between the parent chain and the target sub-chain is realized, and the privacy isolation effect when the user applies the block chain is effectively improved.
The data processing method in this embodiment is applied to an open grant link system based on a parent-child chain architecture, referring to fig. 3, fig. 3 is a schematic diagram of the open grant link system based on the parent-child chain architecture in this embodiment, the open grant link system based on the parent-child chain architecture is composed of three layers, namely, a base layer, an application layer, and a user layer, where the base layer includes function modules such as child chain creation, child chain activation, child chain update, child chain closing, child chain routing, and child chain monitoring, the application layer includes function modules such as application deployment, application invocation, and application migration, and the user layer includes function modules such as user registration, account generation, and account authorization. Furthermore, the sub-chain creation function module is used for creating the sub-chain, the sub-chain activation function module is used for activating the sub-chain, the sub-chain update function module is used for updating information of the sub-chain, the sub-chain closing function module is used for closing the sub-chain, the sub-chain routing function module is used for achieving routing of access of the sub-chain, and the sub-chain monitoring function module is mainly used for monitoring the network operation condition of the sub-chain. The application deployment function module is used for addressing and positioning to a specific sub-chain through the sub-chain routing module, implementing application contract deployment operation and realizing deployment operation experience of one chain; the application calling function module is used for addressing and positioning to a specific sub-chain through the sub-chain routing function module, implementing application contract calling operation and realizing calling operation experience of one chain; and the application migration function module is used for forking and migrating the corresponding child chain from the parent chain. The user registration function module is used for registering information for a user, the account generation function module is used for generating an account number for the user, and the account authorization module is used for authorizing access to the account through an application sub-chain administrator. It is to be understood that, for convenience of description, the open license chain system based on the parent chain architecture will be referred to as a system in the following.
On one hand, a user can register the user with the account generation function module through the user registration function module and the account generation function module of the user layer to generate an account, wherein the generated account has the access right of the mother chain as a default, and one user can use a plurality of sub-chains and also can generate a plurality of accounts. After the user registration is completed and the account generation is completed, the user can log in the account, wherein the account has an access right to the mother chain. Further, based on the service requirement, the user inputs the access operation to be performed and information such as an Identity (unique code) identifier of the sub-chain to be accessed in the system, wherein the sub-chain unique ID identifier is used as the target sub-chain identifier. The system combines the information input by the user with the account information to carry out information coding so as to form a service request. The access operation may include one or more of application deployment, application invocation, account authorization, child chain monitoring, and the like. And then the service request is sent to the basic layer based on the interactive relation between the user layer and the basic layer, so that the target sub-chain needing to be accessed is determined in the basic layer according to the service request, and the access operation in the service request is routed to the target sub-chain.
On the other hand, after receiving a service request sent by a user to the base layer based on the user layer, the system parses the service request, specifically, may decode the information of the service request through a preset decoder, and obtain a target sub-chain identifier input by the user from the service request, where the target sub-chain identifier is used to point to a unique sub-chain in each sub-chain of the block chain. And the access request corresponding to the service request is routed to the target sub-chain.
Step S20, determining a target sub-chain corresponding to the service request according to the target sub-chain identifier;
after the target sub-chain identifier in the service request is obtained through analysis, the system performs identifier matching in each sub-chain of the block chain system through the target sub-chain identifier. After matching is completed, a target sub-chain corresponding to the service request is determined from the sub-chains of the block chain system, so that access operation corresponding to the service request is routed to the target sub-chain in a subsequent process.
Further, the step of determining the target sub-chain corresponding to the service request according to the target sub-chain identifier includes:
step S21, matching the target sub-chain identification with the sub-chain identification of each sub-chain;
step S22, determining a sub chain in each of the sub chains, where the sub chain identifier matches the target sub chain identifier, as a target sub chain.
After the target sub-chain identifier in the service request is obtained through analysis, the system matches the target sub-chain identifier with the sub-chain identifiers of the plurality of sub-chains which are registered and activated to operate, and determines whether the sub-chain with the sub-chain identifier matched with the target sub-chain identifier exists in each sub-chain. And if the sub-chain with the sub-chain identifier matched with the target sub-chain identifier exists in each sub-chain determined by matching, determining the sub-chain as the target sub-chain corresponding to the service request, so that the access operation corresponding to the service request is routed to the target sub-chain in the subsequent process.
Step S30, identifying an access operation in the service request, and routing the access operation to the target child chain.
After determining the target sub-chain, the system identifies an access operation in the service request from information obtained by analyzing the service request, where the access operation may include application deployment, application invocation, account authorization, sub-chain monitoring, and the like in this embodiment, wherein the application deployment is to deploy an application on the sub-chain, the application invocation is to invoke the application in the sub-chain, the account authorization is used to perform authorization audit on an account which needs to access the sub-chain, the sub-chain monitoring is used to monitor the network operation status of the sub-chain, meanwhile, the consistency of the master chain certificate storage data and the block head hash and signature of the target sub-chain area is monitored, by monitoring the consistency of the certificate storing data of the master chain and the hash and signature of the block head of the target sub-chain area, any tampering of the account book of the target sub-chain can be found and the sub-chain dishonest alarm is triggered, so that the whole open permission chain based on the parent sub-chain framework is credible.
The present embodiment provides a data processing method, an apparatus, a device, a medium, and a computer program product, where the data processing method includes: if a service request is received, analyzing a target sub-chain identifier in the service request; determining a target sub-chain corresponding to the service request according to the target sub-chain identifier; and identifying an access operation in the service request, and routing the access operation to the target sub-chain. According to the method and the device, the access operation of the service request is routed to the corresponding target sub-chain according to the target sub-chain identifier in the service request, and the information in the target sub-chain cannot be checked by the parent chain common node, so that service isolation between the parent chain and the target sub-chain is realized, and the privacy isolation effect when a user applies the block chain is effectively improved.
Further, referring to fig. 4, a second embodiment of the data processing method of the present application is proposed based on the first embodiment of the data processing method of the present application, and in the second embodiment, the data processing method further includes:
step S40, receiving a registration request, and acquiring the sub-chain attribute information in the registration request;
step S50, registering the sub-chain in the parent chain corresponding to the registration request according to the sub-chain attribute information;
and step S60, outputting the sub chain identifier of the sub chain to perform sub chain positioning based on the sub chain identifier.
It can be understood that, when the user has a registration requirement, one or more sub-chains may be registered in the system according to an actual requirement, so as to perform access operations such as application deployment, application invocation, account authorization, sub-chain monitoring, and the like on the sub-chains in the following. When a user registers a sub-chain, the user can input sub-chain attribute information and account information such as a network node list of the sub-chain, a public key list of a verifier, a consensus algorithm, a bottom network type and the like into the system, the user layer of the system performs information coding on the basis of the sub-chain attribute information and the account information input by the user to form a registration request, and the registration request is sent to the base layer on the basis of an interactive relation between the user layer and the base layer so that the system can register the sub-chain in a corresponding parent chain according to the registration request in the base layer. The sub-chains and the corresponding parent chains may adopt the same underlying network type, or may adopt different underlying network types, for example, the parent chain adopts a citia (container Inter-entity Trust Automation), the sub-chains may adopt Fabric/citia, the citia is a block chain frame supporting an intelligent contract facing enterprise-level application, the Fabric is a network topology, in which all nodes are interconnected with all other nodes, and is generally described as a matrix similar to a woven square, and is therefore referred to as a "structure".
It can be understood that the sub-chain corresponding to the sub-chain attribute information may be a sub-chain newly created by creating a corresponding unit through the sub-chain, or may be an application sub-chain obtained by performing application migration from a parent chain. Specifically, the formation process of the application subchain may be: the system copies the copy of the master chain in a packing or synchronous node branching mode, and the master chain normally operates at the moment; then, replacing the management node key and the verifier key of the copy of the mother chain with a new key system; and finally, restarting the copy of the parent chain, namely completing the migration of the application from the parent chain to the single chain, and migrating the application to the private application sub-chain of the parent chain according to a sub-chain creation flow of a base layer, so that the management of the sub-chain is completely responsible for the sub-chain, and the parent chain is only responsible for monitoring and endorsement of the non-tampering property of the sub-chain. The application is migrated from the parent chain to the child chain in a bifurcation mode, so that the usability of historical data can be ensured, and a user can select a private account book according to business flow because the application of the parent chain can be migrated to the child chain as required.
It can also be understood that the sub-chain corresponding to the sub-chain attribute information may also be an existing sub-chain, for example, a sub-chain created by another account, that is, the user may request to perform a business operation in another sub-chain created by another person, for example, to deposit evidence to the sub-chain of another person or to obtain evidence from the sub-chain of another person. However, since the account used by the user to send the service request does not have access rights to other sub-chains, the account authorization function module is required to authorize the account to access through the application sub-chain administrator, and after the account is authorized, the system can perform corresponding service operations in other sub-chains.
Further, when the system receives the registration request through the base layer, the registration request is analyzed first, and specifically, the information of the registration request may be decoded, so as to obtain the sub-chain attribute information in the registration request. After acquiring the sub-chain attribute information, the system registers the sub-chain according to the acquired sub-chain attribute information and the parent chain corresponding to the registration request, and generates an initial sub-chain. Further, the system performs trusted certificate storage policy configuration on the generated initial child chain in the base layer, specifically, obtains a pre-configured trusted certificate storage policy (such as selectable block head/hour/day/month), and uploads a child chain block head hash or a block head packing hash of a certain period (such as hour/day/month) and the trusted certificate storage policy to the corresponding parent chain certificate according to the trusted certificate storage policy, and the process is implemented by a trusted certificate storage program, where the child chain needs to grant the program access right to the block head. The specific implementation process is as follows: the program reads the signatures of the block head and the verifier from the sub-chain according to the credible evidence storing strategy, simultaneously reads a verifier public key list registered in advance from the mother chain, and stores the block hash into the mother chain sub-chain management special contract after verifying that the verifier public key list is consistent and the signature is correct, and registers the sub-chain in the mother chain, namely completing the creation of the sub-chain.
Further, the system generates a sub-chain unique ID identifier (i.e., a sub-chain identifier) after the registration of the sub-chain is completed, and outputs the generated sub-chain identifier from the base layer to the user layer, so that the user can acquire the sub-chain identifier of the registered sub-chain, and the user can rapidly locate the corresponding sub-chain based on the sub-chain identifier when the user subsequently needs to access the sub-chain, thereby improving the efficiency of data processing.
Further, the step of registering the child chain in the parent chain corresponding to the registration request according to the child chain attribute information includes:
step S51, extracting a network node list, a public key list of a verifier, a consensus algorithm and a network type in the sub-chain attribute information;
and step S52, registering a sub-chain in the parent chain according to the network node list, the public key list of the verifier, the consensus algorithm and the network type.
After acquiring sub-chain attribute information such as a network node list of a sub-chain, a public key list of a verifier, a consensus algorithm, a network type and the like, the system registers the sub-chain in a parent chain, and specifically, provides the child chain with the sub-chain attribute information such as the network node list of the sub-chain, the public key list of the verifier, the consensus algorithm, the network type and the like, so that the parent chain can configure the sub-chain according to the sub-chain attribute information, wherein the network type of the sub-chain can be CITA/Fabric; and after the parent chain completes the configuration of the child chain according to the information of the network node list of the child chain, the public key list of the verifier, the consensus algorithm, the network type and the like, obtaining an initial child chain, and after the initial child chain is configured with a credible evidence storage strategy, completing the creation of the child chain.
Further, after the step of registering the child chain in the parent chain corresponding to the registration request according to the child chain attribute information, the method further includes:
step S100, activating the sub-chain to the sub-chain, so as to route the access operation of the service request to the sub-chain when receiving the service request.
It can be understood that, after the sub-chain is registered in the parent chain, because the sub-chain just created is in an unavailable state at this time, the system needs to activate the target sub-chain to open the sub-chain for operation, and simultaneously, a trusted evidence storing program is started to check the block header of the sub-chain and perform trusted evidence storing in the parent chain. After the creation and activation of the sub-chain are completed, when a user has an access requirement, the user can conveniently perform access operations such as application deployment, application calling, account authorization, sub-chain monitoring and the like on the sub-chain.
According to the embodiment, the sub-chain is registered in the master chain corresponding to the service request according to the service or service requirement of the user, so that the isolation of the private account book is realized, and the security of the private data of the user is improved.
Further, based on the first embodiment of the data processing method of the present application, a third embodiment of the data processing method of the present application is provided, in which the step of routing the access operation in the service request to the target child chain includes:
step A, if the access operation is application deployment, addressing and positioning to the target sub-chain through a sub-chain routing function, and implementing application contract deployment operation in the target sub-chain;
since the access operation of the user to the sub-chain in this embodiment may include one or more of multiple operations such as application deployment, application invocation, account authorization, sub-chain monitoring, and the like, when the system routes the access operation included in the service request to the target sub-chain obtained through registration and activation, the system needs to identify an operation type included in the access operation, and route each operation type included in the access operation to the target sub-chain, so as to implement various functions of the access operation. Specifically, referring to fig. 5, fig. 5 is a first schematic diagram of routing an access operation in the service request to the target sub-chain in the third embodiment of the present application, and if it is determined that the access operation includes application deployment through identification, the system grants a deployment permission of the target sub-chain to an application deployment function module, and then invokes a sub-chain routing function module in a base layer, and addresses and locates the target sub-chain through a sub-chain routing function of the sub-chain routing function module, and implements an application contract deployment operation in the target sub-chain, thereby implementing a deployment operation experience of one chain.
B, if the access operation is application calling, addressing and positioning to the target sub-chain through a sub-chain routing function, and implementing application contract calling operation in the target sub-chain;
further, referring to fig. 6, fig. 6 is a second schematic diagram of routing an access operation in the service request to the target sub-chain in the third embodiment of the present application, and if it is determined that the access operation includes an application call, the system first grants a contract call authority to an application call function module, so that the service system can directly perform the application contract call to the target sub-chain or perform the application contract call through a general application call service, specifically, the system addresses and locates the target sub-chain through a sub-chain routing function and performs the application contract call operation in the target sub-chain, thereby implementing a call operation experience of one chain.
Step C, if the access operation is account authorization, authorizing access to an account corresponding to the service request through an application sub-chain administrator;
further, referring to fig. 7, fig. 7 is a third schematic diagram of routing an access operation in the service request to the target sub-chain in the third embodiment of the present application, and if it is determined that the access operation includes account authorization, it indicates that a user needs to perform an access operation in an existing sub-chain of another person, and therefore needs to access the sub-chain of another person, and since the account does not have access authority to the sub-chain, the system authorizes the account to perform an access through the application sub-chain administrator, so as to perform a corresponding access operation in the sub-chain after being authorized.
And D, if the access operation is subchain monitoring, monitoring the network running condition of the target subchain, and monitoring the consistency of the certificate storage data of the master chain and the subchain block header information and signature.
Further, referring to fig. 8, fig. 8 is a fourth schematic diagram illustrating that an access operation in the service request is routed to the target sub-chain in the third embodiment of the present application, and if it is determined that the access operation includes sub-chain monitoring, the system monitors a network operating condition of the created target sub-chain, and simultaneously monitors consistency of the master chain deposit certificate data with the block head hash and the signature of the target sub-chain region, and monitors consistency of the master chain deposit certificate data with the block head hash and the signature of the target sub-chain region, so that any tampering of the account book of the target sub-chain can be found and a sub-chain dishonest alarm is triggered, thereby ensuring that the entire open permit chain based on the master sub-chain architecture is trusted.
In the embodiment, each operation type included in the access operation is respectively routed to the target child chain, so that unified management of deployment, account authorization and operation docking of a plurality of child chain contracts is realized through child chain routing, and the reliability of the whole open permission chain based on the parent child chain architecture can be improved.
It can be understood that after the sub-chain registration and activation are completed, or the access operation is routed to the target sub-chain, the system may further update the sub-chain or the target sub-chain according to a request of the user, specifically, update information such as a node list of the sub-chain or the target sub-chain and a verifier public key, and specifically, complete the sub-chain update through the sub-chain update function module.
It can also be understood that after the sub-chain registration and activation are completed, or the access operation is routed to the target sub-chain, the system may close the sub-chain or the target sub-chain according to a request of a user, specifically, when the sub-chain or the target sub-chain exits, a sub-chain closing function module is needed, a parent chain "closes" the state of the sub-chain or the target sub-chain, and stops the trusted deposit of the trusted deposit program, and at this time, the sub-chain routing function module may not find the sub-chain or the target sub-chain (it is located that the sub-chain or the target sub-chain is closed).
Further, when the performance of a single physical chain cannot meet the same service requirement, a plurality of sub-chains can be established by adopting the idea of 'database partitioning and table partitioning', and historical data (more than five years) and active data (nearly five years) are distributed, so that the service requirement is met.
