The following describes in detail the embodiments of the present application with reference to the drawings attached hereto.

In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular system structures, interfaces, techniques, etc. in order to provide a thorough understanding of the present application.

The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship. Further, the term "plurality" herein means two or more than two. In addition, the term "at least one" herein means any one of a plurality or any combination of at least two of a plurality, for example, including at least one of A, B, C, and may mean including any one or more elements selected from the group consisting of A, B and C.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a block chain platform system provided in the present application. The present application provides a blockchain platform system 10, where the blockchain platform system 10 includes blockchain platforms 20 belonging to each party, that is, when a plurality of blockchain participants exist, each party deploys and maintains a set of independent and associated blockchain platform 20, and it is possible to implement the functions of independently controlling resource allocation, deployment and establishment of respective blockchains, and management, monitoring, maintenance and the like of the blockchain for different blockchain participants, that is, the blockchain platform system 10 provided by the present application is a multi-centralized and decentralized blockchain platform system 10. Compared with the traditional block chain platform system 10 designed based on a centralized architecture, on one hand, different block chain participants independently control respective block chain platforms 20 and have independent front-end and back-end services, so that the ownership problems of management, maintenance and the like of the block chain platform system 10 are solved; on the other hand, due to the multi-centralization and decentralized architecture design of the block chain platform system 10, each block chain platform 20 has an independent data storage service, distributed accounting and storage of block chain data are achieved, the system reliability problem caused by centralized storage of management operation and maintenance data is reduced to a certain extent, meanwhile, private data of each block chain participant can be completely isolated and cannot be learned by outsiders, and user experience is improved.

Each of the above parties includes an event initiator and an event receiver, nodes are disposed on a management blockchain 30 of both a blockchain platform 20 of the event initiator and a blockchain platform 20 of the event receiver, the blockchain platform 20 of the event initiator is configured to process a blockchain event corresponding to the event initiator through the management blockchain 30, and the blockchain platform 20 of the event receiver is configured to process a blockchain event corresponding to the event receiver through the management blockchain 30. For example, the blockchain platform 20 of the event initiator sends a chain invitation, an ledger invitation, and a chain exit pending blockchain event through the administration blockchain 30, and the blockchain platform 20 of the event recipient receives a chain invitation, an ledger invitation, and a chain exit pending blockchain event through the administration blockchain 30. That is, the blockchain platform 20 of the event initiator and the blockchain platform 20 of the event receiver access the unified administering blockchain 30, and the administering blockchain 30 realizes message transmission, data synchronization, and the like between the blockchain platform 20 of the event initiator and the blockchain platform 20 of the event receiver.

Since the block chain platform system 10 designed based on the multi-centralization and decentralized architecture is provided in the present application, the governance block chain 30 is introduced to form the multi-centralization and decentralized block chain platform system 10 with a chain governance chain, so as to implement message event transmission, data synchronization, and the like between the block chain platforms 20 deployed in the multi-center of the governance block chain 30 processing block chain platform system 10, that is, the configuration of the governance block chain 30 implements message transmission and information sharing between the block chain platforms 20. The message transmission and information sharing among the block chain platforms 20 are realized by introducing message middleware, the process is complex and long, and the design cost is high; in addition, the message middleware is actually independent of each blockchain platform 20, and all data is collected in the message middleware, so that the message middleware is not completely decentralized, and some management and data security related problems exist. Therefore, compared with a mode of performing message transmission and information sharing among the blockchain platforms 20 by setting message middleware, the mode of performing message transmission and information sharing among the blockchain platforms 20 by introducing the governance blockchain 30 is realized, the process of message transmission and information sharing is simple, the development and design costs are low, and the problems related to management and data safety do not exist.

For example, the operation of blockchain platform system 10 is specifically described by taking the pending blockchain event as a chain invitation.

As shown in fig. 3, fig. 3 is an interaction diagram of an embodiment of a processing chain invitation provided in the present application, where a center a is a blockchain platform 20 of an event initiator, a normal chain is a governing blockchain 30, and a center B is a blockchain platform 20 of a certain event receiver; specifically, the center a performs user authority configuration, adds a chain administrator, and the chain administrator creates an application chain a and completes application chain a basic information configuration, where the application chain a basic information specifically may include an application chain a name, an encryption algorithm type (e.g., a conventional algorithm, a national encryption algorithm, etc.), chain creation party information, participant information, an application chain a node, account book information, and the like, and after completing application chain creation, server selection, port allocation, and deployment path setting, the chain administrator can implement automatic deployment of a block chain node and full-flow deployment log query; the chain manager can invite the center B to join the application chain A, and at the moment, the center A calls an intelligent contract of the law chain to inquire the block chain platform 20 which is already connected with the law chain so as to determine the block chain platform 20 which is invited to join the application block chain by the center A; then, the intelligent contract of the central A calling method chain transfers the chain invitation added into the application chain A to the central B; then, after the center B agrees to join the application chain A, the center B sends request feedback information including the encryption key to a legal chain; then, the legal chain determines the required intelligent contract according to the request feedback information and calls the corresponding intelligent contract; at the moment, the center A receives request feedback information which is sent by the center B and comprises an encryption key through an event monitoring mechanism of the intelligent contract; then, the center A generates a second organization certificate of the center B in the application chain A and encrypts the second organization certificate by using an encryption key; then, the center A sends the chain data related to the application chain A to a legal chain, and the legal chain determines the required intelligent contract according to the chain data and calls the corresponding intelligent contract; at the moment, the center B receives the chain data sent by the center A through an event monitoring mechanism of the intelligent contract; then, the center B deploys the nodes of the center B in the application chain A, specifically, the center B inputs node information corresponding to a chain administrator distributed to the application chain A, and the center B generates an organization certificate, a node certificate, a deployment package, a private key and the like and updates the data of the organization node so as to complete the addition of the chain link points of the visual block; then, after joining the application chain a, the center B sends an information update request (e.g., node information, port information, member information, etc.) to the normal chain because the relevant data of the application chain a changes; then, the legal chain forwards the information updating request sent by the center B to the rest of the block chain platforms 20 added to the application chain a; then, the rest of the blockchain platforms 20 that have joined the application chain a receive the information update request forwarded by the legal chain, and update the chain and node data, so as to implement data synchronization between the independent blockchain platforms 20.

According to the implementation mode, each party deploys and maintains a set of independent and associated block chain platform, so that the functions of independently controlling resource allocation, deployment and construction of respective block chains and managing, monitoring and maintaining the block chains of different block chain participants can be realized, and decentralization of a block chain platform system is realized. On one hand, different block chain participants independently control respective block chain platforms and have independent front-end and back-end services, so that the problem of ownership of management and maintenance of a block chain platform system is solved; on the other hand, each block chain platform has an independent data storage service, distributed accounting and block chain data storage are achieved, the problem of system reliability brought by centralized storage of management operation and maintenance data is reduced to a certain extent, meanwhile, private data of each block chain participant can be completely isolated and cannot be learned by outsiders, and user experience is improved. In addition, by introducing the treatment block chain into the block chain platform system, data between each independent block chain platform can be transferred and transmitted through the deployed treatment block chain, so that message events and data synchronization between each multi-center deployed block chain platform in the block chain platform system can be processed.

Referring to fig. 4, fig. 4 is a schematic structural diagram of a block chain platform according to an embodiment of the present disclosure. The present application provides a blockchain platform 20, where the blockchain platform 20 includes a communication circuit 21, a memory 22, and a processor 23, the communication circuit 21 and the memory 22 are respectively coupled to the processor 23, and the processor 23 is configured to execute program instructions stored in the memory 22, so as to implement the following steps of any one of the blockchain event processing method embodiments corresponding to the blockchain platform 20 whose execution subject is an event initiator and the blockchain platform 20 whose execution subject is an event recipient.

Specifically, the processor 23 is configured to control itself and the memory 22 to implement the steps of any embodiment of the blockchain event processing method, whose execution subjects are the blockchain platform 20 of the event initiator and the blockchain platform 20 of the event recipient. The processor 23 may also be referred to as a CPU (Central Processing Unit). The processor 23 may be an integrated circuit chip having signal processing capabilities.

In one embodiment, the blockchain platform 20 is configured with at least a management module for processing the blockchain event to be processed. That is, since the present application provides the blockchain platform system 10 designed based on the multi-centralization and decentralized architecture, the blockchain platforms 20 of all parties included in the blockchain platform system 10 implement message passing and data synchronization through the abatement blockchain 30 accessed by the blockchain platforms 20, so that the blockchain platform 20 can call the abatement blockchain 30 through the management module to implement message passing and data synchronization.

In a specific embodiment, the abatement blockchain 30 performs message forwarding and data synchronization based on intelligent contracts deployed by the abatement blockchain 30. That is, the blockchain platform 20 is able to perform messaging and data synchronization by the management module invoking the intelligent contracts deployed by the governance blockchain 30.

Referring to fig. 5, fig. 5 is a flowchart illustrating a block chain event processing method according to an embodiment of the present application, and it should be noted that the embodiment is not limited to the flowchart shown in fig. 5 if substantially the same result is obtained. As shown in fig. 5, in the present embodiment, an execution subject of the blockchain event processing method is a blockchain platform 20 of an event initiator, and the method specifically includes:

step S51: and sending an event initiation request to the governance block chain.

Since the block chain platform system 10 designed based on the multi-centralization and decentralized architecture is provided in the present application, the governing block chain 30 is introduced to form the multi-centralization and decentralized block chain platform system 10 with a chain governing chain, so as to implement message event transmission and data synchronization between the block chain platforms 20 deployed in multiple centers in the governing block chain 30 processing block chain platform system 10.

In this embodiment, the blockchain platform 20 of the event initiator sends an event initiation request to the administration blockchain 30, where the event initiation request includes a blockchain event to be processed, the blockchain event to be processed is related to an application blockchain in which the blockchain platform 20 of the event initiator sending the event initiation request participates, the event initiation request is forwarded to the blockchain platform 20 of the event receiver by the administration blockchain 30, and both the blockchain platform 20 of the event initiator and the blockchain platform 20 of the event receiver are deployed with nodes in the administration blockchain 30; that is, when the blockchain platform 20 of the event initiator and the blockchain platform 20 of the event receiver are both deployed with nodes on the administration blockchain 30, that is, when both the blockchain platform 20 of the event initiator and the blockchain platform 20 of the event receiver are connected to the administration blockchain 30, both can implement message transmission and information sharing through the administration blockchain 30; the blockchain platform 20 of the event initiator sends the to-be-processed blockchain event related to the application blockchain in which the to-be-processed blockchain event participates to the administration blockchain 30, so that the subsequent administration blockchain 30 can forward the event initiation request sent by the blockchain platform 20 of the event initiator to the blockchain platform 20 of the event recipient. For the blockchain platform 20 of the event receiver, the blockchain platform 20 of the event receiver receives the event initiation request forwarded by the administration blockchain 30, that is, the blockchain platform 20 of the event receiver receives the to-be-processed blockchain event related to the application blockchain in which the blockchain platform 20 of the event initiator participates, which is sent by the blockchain platform 20 of the event initiator, through the administration blockchain 30. That is, message event delivery between the blockchain platform 20 of the event originator and the blockchain platform 20 of the event recipient is achieved through the admin blockchain 30, i.e., message event delivery between two separate blockchain platforms 20 is achieved through the admin blockchain 30.

In a particular embodiment, the abatement blockchain 30 forwards the event initiation request based on an intelligent contract deployed by the abatement blockchain 30. For example, a plurality of intelligent contracts are deployed on the governance block chain 30, each intelligent contract has different method functions, such as some intelligent contracts are responsible for implementing invitations and some intelligent contracts are responsible for implementing notifications; the block chain platform 20 of the event initiator sends an event initiation request to the management block chain 30, and the management block chain 30 determines a required intelligent contract according to the event initiation request and calls the corresponding intelligent contract; at this time, for the blockchain platform 20 of the event receiver, the event initiation request sent by the blockchain platform 20 of the event initiator is received through the event monitoring mechanism of the intelligent contract. That is, the blockchain platform 20 of the event initiator forwards the blockchain event to be processed related to the application blockchain in which the blockchain platform 20 of the event initiator that sends the event initiation request participates to the blockchain platform 20 of the event receiver by calling the intelligent contract deployed on the governance blockchain 30, so that the event initiation request is forwarded by the intelligent contract deployed on the governance blockchain 30.

Wherein the pending blockchain event is not defined. In one embodiment, the pending blockchain event includes at least a chain invitation, an ledger invitation, a chain exit, an ledger exit, and metadata synchronization. The chain invitation is that the blockchain platform 20 of the event initiator invites the rest blockchain platforms 20 to join the established application blockchain. The ledger invitation is an account book for the blockchain platform 20 of the event initiator to invite the other blockchain platforms 20 to join the established application blockchain. Chain exit is the block chain platform 20 of the event initiator chooses to exit a certain application block chain. The ledger exit is that the blockchain platform 20 of the event initiator selects to exit a ledger in an application blockchain. The metadata synchronization is that the blockchain platform 20 of the event initiator synchronizes blockchain metadata with the rest of the blockchain platforms 20, for example, node state synchronization, ledger state synchronization, basic information synchronization of a platform administrator, basic information synchronization of a chain administrator, or basic information synchronization of an application administrator.

In an embodiment, as shown in fig. 6, fig. 6 is a schematic flowchart of an embodiment of a blockchain platform for determining an event recipient provided in the present application, where before sending an event sending request to a governance blockchain 30, the blockchain platform 20 for determining an event recipient needs to be determined, and specifically includes the following sub-steps:

step S61: and sending a query request to the management block chain, and receiving query feedback sent by the management block chain.

In this embodiment, the block chain platform 20 of the event initiator sends an inquiry request to the management block chain 30, after the management block chain 30 receives the inquiry request sent by the block chain platform 20 of the event initiator, the block chain platform 20 of the event initiator gives an inquiry feedback based on the received inquiry request and sends the inquiry feedback to the block chain platform 20 of the event initiator, and at this time, the block chain platform 20 of the event initiator receives the inquiry feedback sent by the management block chain 30, where the inquiry feedback includes each participant who accesses the management block chain 30, so that the block chain platform 20 of the event initiator determines the block chain platform 20 of each participant who has accessed the management block chain 30.

Step S62: and selecting a participant accessing the management block chain as an event receiver.

In this embodiment, the blockchain platform 20 of the event initiator selects the blockchain platform 20 of the participant accessing the governance blockchain 30 as the blockchain platform 20 of the event receiver, so that each subsequent independent blockchain platform 20 can implement message event transmission and data synchronization through the governance blockchain 30.

Of course, in other embodiments, the blockchain platform 20 of the event initiator may also select the blockchain platform 20 of a certain participant or the blockchain platforms 20 of some participants accessing the administration blockchain 30 as the blockchain platform 20 of the event receiver, which is not limited herein.

In one embodiment, in the case that the pending blockchain event is a second chain invitation, the second chain invitation is used to invite the blockchain platform 20 of the event recipient to participate in the application blockchain created by the blockchain platform 20 of the event initiator. For example, taking the to-be-processed blockchain event as the second chain invitation as an example, as shown in fig. 3, the center a is the blockchain platform 20 of the event initiator, the normal chain is the administration blockchain 30, and the center B is the blockchain platform 20 of the event receiver. Specifically, the center a performs user authority configuration, adds a chain manager, and the chain manager creates an application block chain and completes corresponding chain basic information configuration, and completes deployment of the application block chain; the chain administrator may invite the remaining blockchain platforms 20 to join the application blockchain, at this time, the center a calls an intelligent contract of the abatement blockchain 30 to query the blockchain platform 20 of the participant who has already accessed the abatement blockchain 30, so as to determine that the center a wants to invite the blockchain platform 20 of the application blockchain; center a then invokes the intelligent contract of the abatement blockchain 30 to forward the second chain invitation to center B.

In an embodiment, before each blockchain platform 20 accesses the abatement blockchain 30, an initiator of the abatement blockchain 30 needs to initiate establishment of the abatement blockchain 30, where, as shown in fig. 7, fig. 7 is a schematic flow diagram of an embodiment of establishing the abatement blockchain provided by the present application, and the establishment of the abatement blockchain 30 specifically includes the following sub-steps:

step S71: and responding to a deployment instruction input by an initiator of the treatment blockchain, and deploying the nodes of the blockchain platform of the initiator in the treatment blockchain by the blockchain platform of the initiator.

In this embodiment, in response to a deployment instruction input by an initiator of the abatement blockchain 30, the blockchain platform 20 of the initiator of the abatement blockchain 30 deploys a node of the blockchain platform 20 of the initiator in the abatement blockchain 30. Specifically, as shown in fig. 2, after the blockchain platform 20 of the initiator of the administration blockchain 30 is built and configured, that is, after the blockchain platform 20 is deployed, the blockchain platform 20 is authenticated, specifically, the organization information of the deployed blockchain platform 20 is uploaded to authenticate the organization legitimacy of the blockchain platform 20; then, the platform administrator of the blockchain platform 20 of the originator of the abatement blockchain 30 initiates an instruction to deploy the abatement blockchain 30, and the blockchain platform 20 of the originator of the abatement blockchain 30 automatically deploys its nodes in the abatement blockchain 30 in response to the initiated deployment instruction, and at this time, the blockchain platform 20 of the originator of the abatement blockchain 30 temporarily composes the abatement blockchain 30 at the nodes in the abatement blockchain 30.

Step S72: a first chain invitation is sent to the blockchain platform of the invitee.

The blockchain platform 20 of the originator of the abatement blockchain 30 can invite other blockchain platforms 20 to join the abatement blockchain 30, so that messaging and data synchronization between the various blockchain platforms 20 of the multi-center deployment in the blockchain platform system 10 can be subsequently achieved through the abatement blockchain 30. Thus, in this embodiment, the blockchain platform 20 of the originator of the abatement blockchain 30 sends a first chain invitation to the blockchain platform 20 of the invitee to invite other blockchain platforms 20 to join the abatement blockchain 30. Wherein, when the blockchain platform 20 of the invited party accepts the first chain invitation, the blockchain platform 20 of the invited party deploys the nodes of the abatement blockchain 30 based on the received deployment instruction. Specifically, as shown in fig. 2, the blockchain platform 20 of the initiator of the abatement blockchain 30 sends a first invitation to the blockchain platform 20 of the invitee; in the case where the blockchain platform 20 of the invitee accepts the first chain invitation, that is, in the case where the blockchain platform 20 of the invitee agrees to join the abatement blockchain 30, the platform administrator of the blockchain platform 20 of the invitee initiates a deploy abatement blockchain 30 instruction, the blockchain platform 20 of the invitee automatically deploys its nodes in the abatement blockchain 30 in response to the initiated deploy instruction, and at this time, the nodes of the blockchain platform 20 of the initiator of the abatement blockchain 30 in the abatement blockchain 30 and the nodes of the blockchain platform 20 of the invitee in the abatement blockchain 30 form the abatement blockchain 30.

In one embodiment, the blockchain platform 20 of the initiator of the abatement blockchain 30 sends the first chain invitation to the blockchain platform 20 of the invitee in an offline manner. The offline includes, but is not limited to, mail, instant messaging, etc., and is not limited herein. That is, the blockchain platform 20 of the initiator of the abatement blockchain 30 sends the first chain invitation to the blockchain platform 20 of the invitee by mail or instant messaging.

In one embodiment, the first chain invitation information includes a first organization certificate for the invitee's blockchain platform 20 at the abatement blockchain 30. That is, the blockchain platform 20 of the initiator of the abatement blockchain 30 will generate a first organization certificate for the invitee blockchain platform 20 at the abatement blockchain 30 and then send a first chain invitation including the first organization certificate for the invitee blockchain platform 20 at the abatement blockchain 30 to the invitee blockchain platform 20. It will be appreciated that in other embodiments, the information of the first chain invitation may also include the initiator of the first chain invitation event, abatement block chain 30 state information, node information, etc., and is not specifically limited herein.

In one embodiment, upon deploying the invitee's blockchain platform 20 after the nodes of the admin blockchain 30, i.e., after the invitee's blockchain platform 20 deploys the nodes on the admin blockchain 30, based on the received deployment instruction, metadata of the invitee's blockchain platform 20 is sent to the originator's blockchain platform 20 of the admin blockchain 30; therefore, in this embodiment, the blockchain platform 20 of the initiator of the governance blockchain 30 receives the metadata of the blockchain platform 20 of the invitee forwarded by the governance blockchain 30; the metadata of the blockchain platform 20 of the invited party is sent to the governance blockchain 30 by the blockchain platform 20 of the invited party, and is forwarded to the blockchain platform 20 of the originator of the governance blockchain 30 by the governance blockchain 30, so that the metadata of the blockchain platform 20 of the originator of the governance blockchain 30 and the metadata of the blockchain platform 20 of the invited party are synchronized. Of course, the abatement blockchain 30 also forwards the metadata of the invitee blockchain platform 20 to each of the remaining blockchain platforms 20 that have accessed the abatement blockchain 30, thereby achieving metadata synchronization between each of the independent blockchain platforms 20.

In one embodiment, the abatement blockchain 30 synchronizes data based on smart contracts deployed by the abatement blockchain 30. Specifically, the block chain platform 20 of the invited party sends the metadata synchronization information to the governance block chain 30, and the governance block chain 30 determines the required intelligent contract and calls the corresponding intelligent contract according to the metadata synchronization information; at this time, for the blockchain platform 20 of the initiator of the governance blockchain 30 and the remaining blockchain platforms 20 that have accessed the governance blockchain 30, the metadata synchronization information sent by the blockchain platform 20 of the invitee is received through the event monitoring mechanism of the intelligent contract. That is, the blockchain platform 20 of the invited party transfers the metadata synchronization information of the invited party to the blockchain platform 20 of the initiating party of the governance blockchain 30 and the other blockchain platforms 20 that have already accessed the governance blockchain 30 by calling the intelligent contract deployed on the governance blockchain 30, so that data synchronization is performed through the intelligent contract deployed on the governance blockchain 30.

Step S52: and receiving a request feedback message forwarded by the management block chain.

For the blockchain platform 20 of the event receiver, in response to an event initiation request including a to-be-processed blockchain event sent by the blockchain platform 20 of the event initiator, the blockchain platform 20 of the event receiver processes the event initiation request including the to-be-processed blockchain event, so that the blockchain platform 20 of the event receiver obtains a processing result of the to-be-processed blockchain event; at this time, the blockchain platform 20 of the event receiver sends a request feedback message to the management blockchain 30 based on the processing result of the blockchain event to be processed, where the management blockchain 30 forwards the request feedback message to the blockchain platform 20 of the event initiator. That is, the blockchain platform 20 of the event receiver forwards the processing result of the event initiation request including the to-be-processed blockchain event, which is sent by the blockchain platform 20 of the event initiator, to the blockchain platform 20 of the event initiator through the administration blockchain 30, so that the blockchain platform 20 of the event initiator knows the processing result. For the blockchain platform 20 of the event initiator, the blockchain platform 20 of the event initiator receives the request feedback message forwarded by the administration blockchain 30, wherein the request feedback message is sent by the blockchain platform 20 of the event receiver based on the processing result of the blockchain event to be processed.

In one embodiment, the abatement blockchain 30 forwards messages based on smart contracts deployed by the abatement blockchain 30. Specifically, for the blockchain platform 20 of the event receiver, the blockchain platform 20 of the event receiver receives, through an event monitoring mechanism of the intelligent contract, an event initiation request including a to-be-processed blockchain event sent by the blockchain platform 20 of the event initiator, and a platform administrator of the blockchain platform 20 of the event receiver may process the event initiation request including the to-be-processed blockchain event; the blockchain platform 20 of the event receiver sends request feedback information corresponding to the processing result to the administration blockchain 30 based on the processing result of the blockchain event to be processed by the platform administrator. For the abatement block chain 30, the abatement block chain 30 determines the required intelligent contract according to the request feedback information and calls the corresponding intelligent contract. For the blockchain platform 20 of the event initiator, the request feedback information sent by the blockchain platform 20 of the event receiver is received through the event monitoring mechanism of the intelligent contract. That is, the blockchain platform 20 of the event receiver forwards the request feedback information obtained by the blockchain platform 20 of the event receiver based on the processing result of the blockchain event to be processed to the blockchain platform 20 of the event initiator by calling the intelligent contract deployed on the governance blockchain 30, so that the intelligent contract deployed by the governance blockchain 30 is used for message forwarding.

In a specific embodiment, as shown in fig. 8, fig. 8 is a flowchart illustrating an embodiment of processing a second chain invitation by a blockchain platform of an event initiator according to the present application, where a to-be-processed blockchain event includes a second chain invitation, the second chain invitation is used to invite a blockchain platform 20 of an event receiver to participate in an application blockchain created by the blockchain platform 20 of the event initiator, and after the blockchain platform 20 of the event initiator receives a request feedback message forwarded by a administering blockchain 30, the method specifically includes the following sub-steps:

step 81: and generating a second organization certificate of the blockchain platform of the event receiver in the application blockchain, and encrypting the second organization certificate based on the encryption key.

In the case that the event recipient's blockchain platform 20 includes acceptance of the second chain invitation based on the processing result of the blockchain event to be processed, the request feedback information sent by the event recipient's blockchain platform 20 includes an encryption key. Therefore, in this embodiment, when determining that the blockchain platform 20 of the event receiver accepts the second chain invitation, the blockchain platform 20 of the event receiver generates a second organization certificate of the blockchain applied by the blockchain platform 20 of the event receiver, and encrypts the second organization certificate by using the encryption key included in the request feedback information sent by the blockchain platform 20 of the event receiver.

Step 82: and sending the chain data related to the application block chain to the administration block chain.

In this embodiment, for the blockchain platform 20 of the event initiator, the blockchain platform 20 of the event initiator sends chain data related to the application blockchain to the administration blockchain 30, so that the subsequent administration blockchain 30 can forward the chain data to the blockchain platform 20 of the event recipient. For the blockchain platform 20 of the event recipient, the chain data forwarded by the administering blockchain 30 is received, the encrypted second organization certificate is then decrypted using the encryption key, and the blockchain platform 20 of the event recipient is deployed at a node of the application blockchain to join the application blockchain in which the blockchain platform 20 of the event initiator participates. In one embodiment, the chain data includes at least the encrypted second organization certificate. It is to be understood that in other embodiments, the chain data may further include an application blockchain name, a type of encryption algorithm (e.g., a conventional algorithm, a national encryption algorithm, etc.), creator information, participant information, blockchain nodes, ledger information, and the like, which are not specifically limited herein.

In one embodiment, the abatement blockchain 30 forwards application blockchain related chain data based on intelligent contracts deployed by the abatement blockchain 30. For example, the block chain platform 20 of the event initiator sends the chain data to the administration block chain 30, and the administration block chain 30 determines the required intelligent contract according to the chain data and calls the corresponding intelligent contract; at this time, for the blockchain platform 20 of the event receiver, the chain data sent by the blockchain platform 20 of the event initiator is received through the event monitoring mechanism of the intelligent contract. That is, the blockchain platform 20 of the event initiator forwards the chain data to the blockchain platform 20 of the event receiver by calling the intelligent contract deployed on the governance blockchain 30, so that the chain data is forwarded by the intelligent contract deployed on the governance blockchain 30.

Exemplarily, taking a block chain event to be processed as a second chain invitation as an example, the center a is the block chain platform 20 of the event initiator, the normal chain is the administration block chain 30, and the center a is the block chain platform 20 of a certain event receiver. Specifically, after the center B agrees to join the application block chain, that is, after the center B accepts the second chain invitation, the center B sends request feedback information including an encryption key, generated based on a processing result of the second chain invitation, to the legal chain; the legal chain determines the required intelligent contract according to the request feedback information and calls the corresponding intelligent contract; at the moment, the center A receives request feedback information which is sent by the center B and comprises an encryption key through an event monitoring mechanism of the intelligent contract; then, the center A generates a second organization certificate of the center B in the application block chain and encrypts the second organization certificate by using an encryption key; then, the center A sends chain data related to the application block chain to a legal chain, and the legal chain determines a required intelligent contract according to the chain data and calls the corresponding intelligent contract; at the moment, the center B receives the chain data sent by the center A through an event monitoring mechanism of the intelligent contract; then, the center B deploys the nodes of the center B in the application block chain, specifically, the center B inputs node information to a chain manager correspondingly distributed to the application block chain, and the center B generates an organization certificate, a node certificate, a deployment package, a private key and the like and updates the data of the organization node so as to complete the addition of the visualized block chain link points; then, after the center B joins the application block chain, the relevant data of the application block chain changes, so that an information update request (e.g., node information, port information, member information, etc.) is sent to the normal chain; then, the normal chain forwards the information updating request sent by the center B to the rest of the block chain platforms 20 added with the application block chain; then, the rest of the blockchain platforms 20 that have added the application blockchain receive the information update request forwarded by the method chain, and update the chain and node data, so as to implement data synchronization between the independent blockchain platforms 20.

In the above embodiment, the to-be-processed blockchain event related to the application blockchain in which the event initiator participates, which is sent by the blockchain platform of the event initiator, is forwarded to the blockchain platform of the event receiver, and the request feedback information sent by the blockchain platform of the event receiver is received. Therefore, data among the independent block chain platforms are transferred and spread through the deployed management block chain, and message forwarding and data synchronization among the block chain platforms are processed. In addition, each block chain platform is independent, the functions of resource allocation, deployment and construction of each block chain, management, monitoring, maintenance and the like of the block chains can be independently controlled, multi-centralization and decentralized are achieved, each block chain platform has independent data storage service, distributed accounting and block chain data storage are achieved, the problem of system reliability brought after centralized storage of management operation and maintenance data is reduced to a certain extent, meanwhile, private data of each block chain participant can be completely isolated and cannot be learned by outsiders, and user experience is improved.
