Detailed Description

The block chain platform can be used for building a management system (BaaS platform) with functions of centralized management, centralized operation and maintenance and centralized supervision, provides one-stop subchain link building capability, and realizes full-life-cycle management on the whole network, each subchain node and resources. The blockchain platform can also be an application service platform (SaaS platform) with a one-key blockchain application deployment function, and provides efficient and convenient application development, deployment and management environments under a multi-bottom-layer framework for developers. After generating scattered blockchain nodes or complete blockchains based on the blockchain platform, if communication needs to be performed on each node, a communication channel needs to be used.

The communication channel may be referred to as a channel for short, and is a network in which a block chain account in a federation chain creates an independent block chain for performing a service. Channels allow a particular set of peers and applications to communicate with each other within a blockchain network, channels do not actually exist, but rather are logical structures formed by a collection of physical peers. Each channel has a completely independent ledger, which means completely independent blockchains, and completely independent status. An organization may join multiple channels to participate in multiple independent blockchain networks. However, there are differences in the technologies such as rules and data structures of each blockchain platform, and it is difficult to establish a trust mechanism between different platforms, so that cross-platform communication is difficult to implement, and particularly, in the case where a blockchain account belongs to each organization of a federation chain, this phenomenon is particularly obvious, where an organization is a member in the federation chain, and is an entity corresponding to a real scene, and different organizations generate information such as their own identity certificates for interaction and authentication in the federation chain network.

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The channel management method of the block chain platform provided by the embodiment of the application can be applied to the application environment shown in fig. 1. Wherein the terminal 102 communicates with the server 104 via a network. The data storage system may store data that the server 104 needs to process. The data storage system may be integrated on the server 104, or may be located on the cloud or other network server. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, internet of things devices and portable wearable devices, and the internet of things devices may be smart speakers, smart televisions, smart air conditioners, smart car-mounted devices, and the like. The portable wearable device can be a smart watch, a smart bracelet, a head-mounted device, and the like. The server 104 may be implemented as a stand-alone server or as a server cluster comprised of multiple servers. The scheme provided by the embodiment of the application can be realized by the terminal 102; or cooperatively implemented by the terminal 102 and the server 104, wherein both the terminal 102 and the server 104 may be real blockchain nodes, and the terminal 102 and/or the server 104 may also refer to corresponding virtual blockchain nodes.

In one embodiment, as shown in fig. 2, a method for managing channels of a blockchain platform is provided, which is described by taking the method as an example applied to the server 104 in fig. 1, and includes the following steps:

step 202, obtaining an operation instruction sent by a blockchain node connected to a first platform, and if it is determined that the operation instruction is related to a target node connected to a second platform, determining a target blockchain for managing a communication channel, where the first platform and the second platform belong to blockchain platforms in different blockchain networks.

The first platform is a blockchain platform in a blockchain network, the blockchain platform connection comprises one or more blockchain nodes, and a blockchain link point can be a node in a real blockchain or a discrete blockchain link point, and most of the discrete blockchain link points are used for testing or learning.

After the block link point connected to the first platform sends the operation command, the server 104 corresponding to the first platform may determine according to the corresponding relationship or data dependency, and when the operation command is not related to the target node, the target block link may not be scheduled. For example: if the operation command is corresponding to the block link point, the operation command is not related to a target node connected with the second platform; if the operation instruction is a management state or a running state corresponding to the second platform, the operation instruction is not related to a target node connected with the second platform.

When the operation instruction corresponds to the target node, the operation instruction is related to the target node connected with the second platform, because the first platform and the second platform belong to different block chain networks respectively, the rules and data structures between the first platform and the second platform are different, and the trust mechanism between different platforms is difficult to establish, the target block chain for managing the communication channel needs to be determined, and after the target block chain is determined, the first platform generates some request instructions, and the process of information interaction is performed with the target block chain through the request instructions.

And 204, generating permission verification information corresponding to the operation instruction, and sending the permission verification information to the target node through the target block chain.

For the generation process of the authority checking information, it may be that partial data in the operation instruction is directly used as data corresponding to the authority checking information, it may also be that data corresponding to the operation instruction is used as data corresponding to the authority checking information, it may also be a process of performing information integration on the operation instruction, and the information integration may be a data integration process or content integration.

For the data integration of the permission audit information, the process may be to perform format conversion on the operation instruction, or to perform parsing and recombination on some data mapped by the operation instruction, or to start some functions to implement corresponding functions. For example: if the operation instruction is in a data format in the first platform, the operation instruction needs to be converted into a data format of a target block chain or a second platform; if the operation instruction can be mapped to a certain preset service function of the first platform, analyzing or recombining the service logic for realizing the preset service function so as to adapt to the data format of the target block chain or the second platform; and if the operation instruction can trigger an event function for generating the interaction event, starting the event function corresponding to the operation instruction to generate the authority auditing information.

And integrating the content of the authority auditing information. The process may be to perform feature extraction on the operation instruction, or may be to perform feature extraction on a function corresponding to the operation instruction. For example: if the operation instruction points to data such as table images, texts, video and audio files and the like, performing feature extraction on the data so as to obtain required authority verification information; if the operation instruction triggers certain functions or events, the functions or events are subjected to feature extraction.

After the authority audit information is generated, the target block chain transmits the authority audit information, and the data format corresponding to the authority audit information is one or more of the data format standard, the function standard and the like which accord with the target block chain transmission, so that the request information of the block chain node is conveniently sent to the target node through the target block chain, and the information interaction between the first platform and the second platform is realized.

And after the authority audit information is sent to the second platform, the target node audits the authority audit information and generates an initial audit result of a corresponding channel according to the data rule of the second platform, wherein the initial audit result can be a digital signature and can be some identification or data obtained by generating a block based on a consensus mechanism.

After the initial audit result is generated, if the initial audit result simultaneously conforms to the preset data format of the target block chain, the task execution subject corresponding to the second platform can directly send the initial audit result to the target block chain; and if the initial auditing result does not conform to the preset data format of the target block chain, the initial auditing result needs to be converted according to the rule corresponding to the target block chain to obtain the converted auditing result, and the converted auditing result is sent to the target block chain.

And step 206, acquiring a channel audit result corresponding to the authority audit information through the target block chain, determining a communication channel between the block chain link and the target node based on the channel audit result, and realizing communication between the first platform and the second platform.

And for the obtained channel auditing result, the obtained channel auditing result may represent that the communication channel is forbidden or authorized. If the channel audit result indicates that the communication channel is prohibited from being used, the communication channel may need to be managed by other block chains or schemes, rather than managing the communication between the block chain node and the target node by this target block chain. And if the channel auditing result represents the authorization of the communication channel, determining the communication channel between the block chain link point and the target node according to the operation instruction. For this process of determining the communication channel, it may be a process of adding the block link point to the communication channel where the target node is located, or a process of generating a communication channel between the block link point and the target node.

After the communication channel is determined, the interaction between the first platform and the second platform is realized based on the communication channel. It can be understood that a communication channel is an independent block chain network created for performing a certain service by an organization in a federation chain, the communication between a block chain link point and a target node is realized through the communication channel, the channel is a logical structure formed by a physical peer node set, and each channel can have a completely independent block chain book to ensure the reliability of information interaction.

It can be understood that the target blockchain has a decentralized characteristic, and by applying one or more management means such as data encryption, timestamp, distributed consensus and the like, the nodes distributed on the first platform and connected with the second platform can realize information interaction based on decentralized, so that the problems of high cost, low efficiency, unsafe data storage and the like caused by centralization of the blockchain by the blockchain platform can be solved. For example: the first platform and the second platform are respectively developed, operated, maintained, managed and/or monitored by different platform management organizations, and technical barriers, trust and other problems exist between the different platform management organizations, so that a communication channel needs to be managed based on a target block chain.

In the channel management method of the block chain platform, an operation instruction sent by a block chain node connected with a first platform is obtained, and if the operation instruction is determined to be related to a target node connected with a second platform, a target block chain for managing a communication channel is determined, wherein the first platform and the second platform belong to different block chain networks; generating authority checking information corresponding to the operation instruction, and sending the authority checking information to the target node through the target block chain; and acquiring a channel auditing result corresponding to the authority auditing information through the target block chain, determining a communication channel between the block chain link and the target node based on the channel auditing result, and realizing communication between the first platform and the second platform. Therefore, not only can information interaction be carried out between users connected with one block chain platform in a channel creating mode, but also the users between different block chain platforms can build or join a cross-platform communication channel by depending on a target block chain through corresponding nodes, and the information interaction between the first platform and the second platform is realized. In addition, the related information of the communication channel can be traced back through the target block chain, and the safety of information interaction is guaranteed.

In one embodiment, as shown in fig. 3, determining that the operation instruction is related to the target node connected to the second platform includes:

step 302, analyzing the operation instruction, and determining a service requirement corresponding to the operation instruction.

The operation instruction can be interpreted by the first platform to realize the analysis of the operation instruction, and the analysis process can also be realized by other platforms or some task execution bodies corresponding to the first platform. After the operation instruction is analyzed, the service requirement corresponding to the operation instruction can be determined. The service requirement may be a requirement for establishing a federation or joining a federation, or may be another requirement associated with the target node.

Step 304, obtaining a candidate communication channel corresponding to the second platform based on the target block chain, where the candidate communication channel includes at least one candidate communication node.

Step 306, judging the corresponding relation between the service requirement and the candidate communication node, and determining that the operation instruction is related to the target node connected with the second platform based on the corresponding relation.

When the service requirement does not have a corresponding relation with the candidate communication node, the target node corresponding to the service requirement does not exist in the candidate communication node, so that information interaction is not needed.

When at least one corresponding relation exists between the service requirement and the candidate communication nodes, the target node is determined from the candidate communication nodes, so that the corresponding relation between the service requirement and the target node is clear, and information interaction between the block link node and the target node is convenient to realize.

In this embodiment, the candidate communication node is determined by the target block chain, and the target node is determined based on the correspondence between the candidate communication node and the service requirement. Therefore, the target node is determined according to the service requirement, so that on one hand, many problems caused by data dependency can be reduced, on the other hand, the target node can be determined more accurately, and information interaction among different block chain platforms is facilitated.

Judging the corresponding relation between the service requirement and the candidate communication node, comprising:

step 402, obtaining a block chain service account corresponding to the candidate communication node, and determining a service function corresponding to the block chain service account.

For candidate communication nodes connected to the second platform, the candidate communication nodes may be virtual nodes or real devices, and one candidate communication node may correspond to one or more blockchain service accounts, which may provide some or some service function when the blockchain service account belongs to an organization or an individual, and the service function may be an authorization function.

Step 404, obtaining a corresponding relation between the service requirement and the candidate communication node based on the corresponding relation between the service requirement and the service function.

In this embodiment, the service function is determined by the blockchain service account, and the corresponding relationship between the service requirement and the candidate communication node is determined according to the corresponding relationship between the service function and the service requirement. Therefore, the alliance information between the first platform and the second platform can be directly determined, so that a communication channel can be generated or created, and the communication security of the nodes of different blockchain platforms is higher.

In one embodiment, as shown in fig. 5, the target block chain corresponds to a first predetermined data format and a second predetermined data format, and the first predetermined data format and the second predetermined data format are both data formats specified by the target block chain and are used for converting data output by the first platform into the data formats. The first preset data format is used for determining a data type or a function type corresponding to a channel authority acquisition function, and the second preset data format is used for determining a data type or a function type corresponding to a demand to be authorized; for specific format requirements, the first preset data format and the second preset data format may have the same data type or different data types. The authority verification information corresponding to the generated operation instruction includes:

step 502, determining a channel permission obtaining function in the operation instruction, and converting the channel permission obtaining function based on a first preset data format to obtain a converted channel permission obtaining function.

The channel permission obtaining function is used for obtaining the channel permission, and the converted channel permission obtaining function not only has the function of the channel permission obtaining function, but also has the convenience brought by the first preset data format, and is beneficial to reducing the influence caused by format problems.

Step 504, determining a to-be-authorized requirement of the operation instruction, and converting the to-be-authorized requirement based on a second preset data format to obtain a converted to-be-authorized requirement.

The requirement to be authorized may refer to a specific authorization requirement, or may be a requirement corresponding to other related functional requirements, and the compatibility problem of data between different blockchain platforms can be avoided through the converted substitute authorization requirement.

Step 506, combining the converted to-be-authorized requirement with the converted authorization judgment function to obtain the authorization audit information.

In this embodiment, data conversion is performed according to a preset data format to adapt to a data standard of a target block chain, and since the first platform performs data format conversion instead of format conversion based on the target block chain, a certain amount of computing resources can be saved.

In one embodiment, as shown in fig. 6, the channel audit result includes channel authorization information, and the generation of the channel audit result includes:

step 602, determining a plurality of permission auditing accounts based on the communication channel of the target node, and determining permission auditing nodes corresponding to the permission auditing accounts.

And step 604, after each authority checking account respectively checks the authority checking information, generating channel authorization information based on each authority checking node.

In this embodiment, a communication channel of a target node is used to determine a permission audit account, and after each permission audit account corresponding to the channel respectively audits permission audit information, channel authorization information is generated based on a permission audit node corresponding to the permission audit account. Therefore, the authority checking information can not be diffused to each node in a large scale, the checking efficiency can be guaranteed, and the communication enables the authority checking accounts to form a set so as to avoid the large-scale diffusion of the authority checking information.

The method further comprises the following steps: and the application target block chain stores the authority verification information, the channel verification result and the flow information generated by the channel verification result between the first platform and the second platform.

In this embodiment, after the information is stored in the target block chain, the characteristics of the block chain in the aspects of non-falsification, decentralization and the like can be fully exerted, and the permission audit information, the audit process and the audit result can be traced, so that a trust mechanism corresponding to nodes connected to different platforms of the target block chain can be better established, a cross-platform alliance chain can be established, and cross-platform communication can be realized.

In one embodiment, determining the communication channel between the block link node and the target node based on the channel audit result comprises:

after receiving the channel authorization information, generating a communication channel between a block chain link point connected with the first platform and a target node by using the target block chain; or after receiving the channel authorization information, applying the target block chain to connect the block chain link point connected by the first platform to the communication channel where the target node is located.

In this embodiment, the communication flow can be accelerated by generating the communication channel, the possibility of information congestion is reduced, and the excessive occupation of computing resources due to excessive communication channels can be avoided by connecting to the communication channel. Therefore, the two data processing modes can be used for adjusting the overall process of data interaction so as to facilitate cross-platform information interaction.

The target block chain is taken as a management chain of an organization union, the first platform and the second platform are collectively called block chain platforms, and service functions in the block chain platforms are discussed.

A bottom layer interaction module: and defining an interaction standard and an interaction method of the BaaS platform to the bottom infrastructure, and operating and processing the bottom nodes according to the channel configuration.

In an optional embodiment, the target block chain is used as a channel management chain of the BaaS platform, and has two functions, specifically as follows:

The channel information interaction function is as follows: the function defines the format and the specification of the BaaS platform for uplink storage of the channel information, and the standard format and the method for interacting with the channel management chain, and provides the modified record tracing of the channel information.

Relative to the first platform, users of the first platform are users of the BaaS platform, users of the second platform are other users, and the other users comprise other isomorphic and heterogeneous BaaS platform users and non-BaaS platform users; based on the same principle, compared with the second platform, the user of the second platform is the user of the BaaS platform, the user of the first platform is other users, and the other users comprise other isomorphic and heterogeneous BaaS platform users and non-BaaS platform users.

In an alternative embodiment, as shown in fig. 7, the blockchain accounts in the blockchain platform interact through an internal interface of the platform, and the blockchain platforms interact through an interface of a management chain for managing cross-platform communication, for example: the method comprises the steps that an organization corresponding to a block chain account in the BaaS platform and an interactive interface of the BaaS platform service are established; the management chain API is an external interface for interaction between the non-native BaaS platform organization and the native BaaS platform management chain, and is authorized to be accessible.

3. calling a channel information management function through a management chain API (application program interface) to uplink and store the information added into the channel;

4. and the channel configuration management module updates the configuration of the bottom infrastructure through the bottom interaction module.

In an optional embodiment, as shown in fig. 9, taking the blockchain account number of the second platform as a main descriptor, in a scenario of discussing authorization, an overall process of adding the blockchain account number of the second platform into a communication channel where a target blockchain of the second platform is located includes:
