Description
Technical Field
The present invention relates to the field of block chains, and in particular, to a multi-level cross-chain cooperation method and apparatus, a computer device, and a storage medium.
Background
In the multi-level chain-crossing collaboration process of the block chain, at least two scenes exist, and management mechanisms on different collaboration chains at one level and the same level simultaneously perform collaborative management on a lower-level collaboration chain; secondly, in the execution process of the cooperative instruction, the cooperative instruction may not be executed normally due to the lack of some cooperative rules.
In the first scenario, the existing method is solved by adopting a mode of negotiation under a chain, that is, whether to issue a coordination instruction or a coordination rule is issued by different management mechanisms under the chain in a conference mode or the like, and then the coordination instruction or the coordination rule is directly issued by the management mechanism initiating the request, so that the process is not open and transparent enough, the efficiency is low, data is easily tampered, and the management mechanisms at the same level cannot be traced when problems occur. In the second scenario, the existing method may request the part of the collaboration rule that is missing by itself from other management entities in the same chain or from other collaboration chains in the same chain, so that the collaboration instruction can be executed successfully. However, since the collaborative data belongs to the down-link storage, and the management organization has the respective down-link collaborative rule database, the existing method causes that the data is easily tampered, and the data transmission is safe and low in efficiency.
Therefore, in the existing block chain management, there is a problem of low collaborative security due to the need of multi-level cross-chain collaboration through down-chain negotiation and down-chain scheduling.

The multi-level cross-chain collaboration method provided by the application can be applied to an application environment as shown in fig. 1, wherein a computer device communicates with a server through a network. The computer device may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, among others. The server may be implemented as a stand-alone server or as a server cluster consisting of a plurality of servers.
In an embodiment, as shown in fig. 2, a multi-level cross-chain collaboration method is provided, which is described by taking the method as an example applied to the server in fig. 1, and includes the following steps S10 to S40:

I.e. one authority corresponding to one level number of a block chain. Collaboration types include, but are not limited to, request collaboration, data collaboration on a chain.
It should be noted here that, the level number of the block chain in which the coordination data is included in one coordination information and the number of the block chain in which the coordination data is included may be multiple, and the specific number is not limited.
By acquiring the collaborative information, the level number of the block chain where the collaborative data is located and the number of the block chain where the collaborative data is located, which are included in the collaborative information, can be multiple, so that the multi-level cross-chain collaborative information can be processed, and the multi-level cross-chain collaborative security can be improved.
And S20, acquiring at least one block chain corresponding to the hierarchy number of the block chain where the collaborative data is located as the block chain to be collaborative.
In step S20, the to-be-coordinated blockchain is a blockchain that needs to process coordinated data.
It should be understood that the at least one blockchain corresponding to the level number of the blockchain in which the collaborative data is located refers to a management mechanism in which the blockchain that is the same as or corresponds to the level number of the blockchain in which the management mechanism initiated by the collaborative data is located. For example, when a plurality of administrators belonging to one or more collaboration chains collaboratively manage a certain blockchain, when a collaboration request is initiated by the certain blockchain, collaboration data is carried in the certain blockchain, and one or more collaboration chains are blockchains to be collaborated, and the hierarchy numbers of the administrators correspond to the hierarchy number where the collaboration data in the certain blockchain is located.
It should be noted here that the cooperation chain is a kind of blockchain, and is used for cooperating with the cooperation instruction and the cooperation rule of the management mechanism on the blockchain.
By acquiring the block chain to be coordinated, real-time chain crossing processing is performed on the coordinated data by using the block chain to be coordinated, and the conditions of under-chain negotiation and under-chain scheduling are reduced, so that the multi-level chain crossing coordination safety is improved.
And S30, acquiring a cooperation mode corresponding to the cooperation type from the preset cooperation mode set as a target cooperation mode.
In step S30, the preset coordination mode set is a set storing coordination modes. The preset cooperation mode set includes, but is not limited to, a request cooperation and a data cooperation on a chain.
The target cooperation method is a target method for processing cooperation data.
In step S30, it is specifically:
and when the cooperation type is the on-chain request cooperation, acquiring an on-chain request cooperation mode, and taking the on-chain request cooperation mode as a target cooperation mode.
And when the cooperation type is data cooperation, acquiring a data cooperation mode, and taking the data cooperation mode as a target cooperation mode.
The scope of the usage of the on-chain collaboration request mode includes, but is not limited to, on-chain collaboration request and/or on-chain cross-chain collaboration request. The method for requesting collaboration on the same block chain refers to a mode that management mechanisms at the same level in the same block chain perform on-chain collaboration request processing on collaboration data. The method for requesting collaboration on a cross-chain link refers to a mode that management mechanisms at the same level in different block chains perform on-chain request collaboration processing on collaboration data.
The scope of use of data collaboration includes, but is not limited to, co-chaining data collaboration and/or cross-chaining data collaboration. The same-chain data cooperation refers to a mode that management mechanisms at the same level in the same block chain perform data cooperation processing on cooperation data. The inter-chain data cooperation refers to a data cooperation processing mode of the cooperative data by the management mechanisms of the same level in different block chains.
The cooperative mode corresponding to the cooperative type is acquired from the preset cooperative mode set and is used as a target cooperative mode, the target cooperative mode is adopted to perform cooperative processing on the block chain to be cooperative, the conditions of under-chain negotiation and under-chain scheduling are reduced, and therefore the multi-level cross-chain cooperative security is improved.
And S40, performing cooperative processing on the cooperative data by adopting the block chain to be cooperative based on the target cooperative mode to obtain a cooperative result.
In step S40, the above-described cooperation processing refers to a processing procedure relating to the target cooperation method.
The collaboration result includes, but is not limited to, a permission to send the collaboration instruction, a permission to send the collaboration rule, a non-permission to send the collaboration instruction, and a non-permission to send the collaboration rule. It is understood that the collaboration result herein varies with the target collaboration mode.
In step S40, when the target collaboration mode is the on-chain request collaboration mode, it specifically includes the following steps S401 to S403:
s401, based on the on-chain request cooperation mode, generating a request proposal on a cooperation chain and sending a cooperation request to a block chain to be cooperated, wherein the cooperation request comprises cooperation data.
And S402, based on a preset cooperative processing mode, performing cooperative processing on the cooperative request by using the block chain to be cooperative to obtain a processing result.
And S403, determining a collaboration result corresponding to the request proposal on the collaboration chain based on the processing result.
For step S401, the above-mentioned collaboration on-chain request proposal refers to a task of performing on-chain collaboration request on collaboration data. The manner of generating the above request proposal on the collaboration chain includes, but is not limited to, calling a generating function. For example, invoking the issue function in request collaboration on a co-chained chain generates a request proposal on a co-chained chain.
It is to be understood that the manner of generating the above-mentioned request proposal on the collaboration chain is only illustrative and is not specifically limited herein.
For step S402, it is specifically:
determining the request type of the cooperation request by adopting the block chain to be cooperated, and generating a request proposal on the block chain to be cooperated according to the request type;
broadcasting the proposal to be submitted on the to-be-coordinated link by adopting the to-be-coordinated block chain so as to enable the mechanism receiving the proposal to be submitted on the to-be-coordinated link to vote the proposal to be submitted on the to-be-coordinated link to obtain a voting result;
and summarizing all voting results based on a preset processing mode to obtain a processing result.
When the request type of the cooperation request is a cooperation request on the same link, a certain management mechanism initiates a request, as a cooperation instruction or a cooperation rule is issued, a cooperation request on the same link is initiated to other management mechanisms at the same level, a request proposal on the link to be cooperated is generated, and the other management mechanisms vote for the request proposal on the link to be cooperated. After receiving the cooperative request on the same chain, other management mechanisms at the same level generate a proposal request on a chain to be cooperative, which is issued by a cooperative instruction/rule, according to the request type, the proposal request on the chain to be cooperative is stored on the chain, and the other management mechanisms at the same level inform related mechanism personnel to vote through a broadcast event after the proposal request on the chain to be cooperative is generated. And the related institution personnel votes for the proposal requested on the chain to be coordinated on the chain, and passes or refuses the proposal requested on the chain to be coordinated according to the corresponding voting strategy. When the number of votes by the authority reaches a preset number, for example, the preset number is 10, the number of votes by the authority reaches 10, and the result is passed. And acquiring all voting results, counting the voting results, and passing or refusing the proposal request on the to-be-coordinated link according to a corresponding voting strategy. The corresponding voting strategy includes, but is not limited to, minority-compliant majority, priority, principle.
When the request type of the collaboration request is a collaboration request on a cross-chain, a certain management mechanism initiates a request, such as sending a collaboration instruction or a collaboration rule, the cross-chain initiates a collaboration request on the cross-chain to other management mechanisms at the same level, a request proposal on a chain to be collaborated is generated on the chain corresponding to the cross-chain, and the other management mechanisms are waited to vote on the request proposal on the chain to be collaborated. After receiving the collaboration request on the cross-chain, other management mechanisms at the same level of the cross-chain generate a proposal to be requested on the chain to be collaborated, which is sent by a collaboration instruction/rule, on the chain corresponding to the cross-chain according to the request type, the proposal to be requested on the chain to be collaborated is stored on the chain, and the proposal to be requested on the chain to be collaborated is notified to relevant mechanism personnel for voting through a broadcast event after being generated. And the related institution personnel votes for the proposal requested on the chain to be coordinated on the chain, and passes or refuses the proposal requested on the chain to be coordinated according to the corresponding voting strategy. When the number of votes by the authority reaches a preset number, for example, the preset number is 10, the number of votes by the authority reaches 10, and the result is passed. And obtaining all voting results of different block chains, counting the voting results, and passing or refusing to request proposal on the to-be-coordinated chain according to a corresponding voting strategy. The corresponding voting strategy includes, but is not limited to, minority-compliant majority, priority, principle.
For step S403, it is specifically: and if the processing result is that the request proposal on the to-be-coordinated chain passes, the coordinated result is that a corresponding coordinated instruction or rule is issued to a subordinate coordinated chain, and the processing result is notified to a relevant management mechanism. It should be noted here that the collaboration result includes cross-chain delivery and co-chain delivery, and the specific collaboration result is adapted to the collaboration type.
Through the steps, the request collaboration on the same chain or a cross-chain is realized, so that the collaboration request can be carried out on the chain, the generated request proposal on the chain to be collaborated can be stored on the chain, and due to the characteristics of 'non-tampering', 'traceability' and the like of the block chain, a management mechanism for issuing collaboration instructions or collaboration rules can be positioned and issued through the request proposal to be collaborated when the collaboration has problems, so that the security of the request collaboration on the multi-level cross-chain is improved.
In step S40, when the target collaborative manner is the data collaborative manner, it specifically includes the following steps S404 to S407:
s404, sending a data cooperation request to the block chain to be cooperated based on a data cooperation mode, wherein the data cooperation request comprises a request type.
S405, acquiring a request mode corresponding to the request type from a preset request mode set as a target request mode.
And S406, performing cooperative processing on the data cooperative request by using the block chain to be cooperative based on the target request mode to obtain a processing result.
And S407, determining a cooperation result corresponding to the data cooperation request based on the processing result.
For step S406, it specifically is:
broadcasting the data cooperation request by adopting a block chain to be cooperated so that a mechanism receiving the data cooperation request votes for the data cooperation request to obtain a voting result;
and summarizing all voting results based on a preset processing mode to obtain a processing result.
When the target request mode is the same-link data cooperation request, if the management mechanism initiating the request has the cooperation rule base reading permission of the corresponding management mechanism, the corresponding cooperation rule is directly read and stored in the cooperation rule base of the management mechanism. And if the management mechanism initiating the request does not obtain the corresponding authority of the collaborative rule base corresponding to the management mechanism, initiating the request to the corresponding management mechanism in a mode of broadcasting the event in the chain. It should be understood that there is a organizational level collaboration rule base within the same collaboration chain, stored on the chain. When the management organization creates the own collaborative rule base, the authority can designate which management organizations share the collaborative rule base of the organization through authority control. After that, the sharing can be cancelled or added through the authority control. After receiving the request, the management organization chooses to approve or reject the request. And if the request is approved, giving the authority the reading authority of the own collaborative rule base through authority control. If the request is denied, the authority is also notified by means of an in-chain broadcast event. If the request of the management mechanism initiating the request is agreed, the corresponding cooperation rule base reads the needed cooperation rule, the cooperation rule is stored in the cooperation rule base, and after the reading is finished, the corresponding management mechanism is informed in the form of an in-chain broadcast event. After receiving the notification of the completion of reading, the management organization can decide whether to cancel the reading authority of the management organization for the own collaborative rule base through authority control and notify the corresponding management organization of the decision in a form of intra-chain broadcasting.
When the target request mode is a cross-chain data collaboration request, the management mechanism may request a certain industry or a collaboration rule meeting a certain condition from the management mechanisms in other collaboration chains at the same level, and broadcast an event to notify the corresponding management mechanisms in other collaboration chains in a cross-chain manner. The authority receiving the request may decide whether to share the collaborative rules. And if the request is approved, reading the requested cooperation rule from the own cooperation rule base, and sending the cooperation rule to the requester in a cross-chain mode. If the request is denied, the requestor also needs to be informed of the reason for the denial in a cross-chain fashion. And the requester receiving the cooperation rule stores the cooperation rule in the own cooperation rule base of the chain.
Through the data collaboration, management mechanisms in the peer collaboration chain can share data, and the collaboration can be executed more efficiently. And the cooperative data and the data request are stored on the chain, so that the authenticity and the effectiveness of the cooperative data are ensured on one hand, and the flow of the cooperative data can be monitored on the other hand, thereby improving the safety of multi-level cross-chain data cooperation.
The multi-level cross-chain cooperation method provided by the embodiment of the invention obtains cooperation information, wherein the cooperation information comprises cooperation data, a level number of a block chain where the cooperation data is located and a cooperation type; acquiring at least one block chain corresponding to the level number of the block chain where the collaborative data is located as a block chain to be collaborative; acquiring a cooperation mode corresponding to the cooperation type from a preset cooperation mode set as a target cooperation mode; and performing cooperative processing on the cooperative data by adopting the block chain to be cooperative based on the target cooperative mode to obtain a cooperative result.
