Description
Technical Field
The present disclosure relates to the field of blockchains, and in particular, to an apparatus and method for information disclosure and transaction processing for a federation chain.
Background
This section provides background information related to the present disclosure, which is not necessarily prior art.
In the past few years, blockchain technology has gained a tremendous momentum. This is mainly due to the success of bitcoin crypto currency. Blockchains (also referred to as distributed ledgers) are essentially simply appended data structures maintained by a set of nodes that are not fully trusted by each other. All nodes in a blockchain network agree on an ordered set of blocks, each containing multiple transactions, so the blockchain can be viewed as a log of ordered transactions. Blockchains are of several types, such as public blockchains, private blockchains, and federation blockchains. In the present disclosure, reference is primarily made to federated blockchains, i.e., federated chains.
For example, in the conventional method, it is very difficult for many small and medium-sized enterprises to transform the enterprises through the inventory system. The assets of small and medium-sized enterprises are relatively small in size and therefore cannot become marketed companies. It is difficult for small and medium-sized enterprises to raise funds. If it wants to reform a business in the equity system and create a consortium of small and medium-sized businesses in conjunction with other businesses, there is a lack of an equity transfer platform that does not require mutual trust. How to maintain trust between each other if it is intended to create a stock platform for a company. How to maintain authentication of information when a small business wants to disclose business information on a platform. How fair and invariance are maintained when small businesses and investors want to move stocks across platforms. Furthermore, how to monitor the federation platform in the event of false information disclosure and illegal migration. These challenges need to be addressed.

Detailed Description
Examples of the present disclosure will now be described more fully with reference to the accompanying drawings. The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses.
Example embodiments are provided so that this disclosure will be thorough, and will fully convey the scope to those skilled in the art. Numerous specific details are set forth such as examples of specific components, devices, and methods to provide a thorough understanding of embodiments of the present disclosure. It will be apparent to those skilled in the art that specific details need not be employed, that example embodiments may be embodied in many different forms, and that neither should be construed to limit the scope of the disclosure. In certain example embodiments, well-known processes, well-known structures, and well-known technologies are not described in detail.
The disclosure provides an apparatus and method for information disclosure and transaction processing for a federation chain in which a first node and a second node are included. The device for information disclosure and transaction processing of the alliance chain mainly comprises two modules, an information disclosure module and a transaction processing module. An information disclosure module may disclose information about the second node in the federation chain based on operation of the first node. The transaction processing module may employ the federation chain's operating mechanism for transaction processing based on the disclosed information.
For better understanding of the technical solutions of the present disclosure, the following describes in more detail the apparatus and method for information disclosure and transaction processing of a federation chain of the present disclosure. The following embodiments describe apparatuses for information disclosure and transaction processing of a federation chain according to the present disclosure, taking a stock trading platform as an example. However, it should be apparent to those skilled in the art that such description is merely exemplary, and the present disclosure is not limited thereto. Of course, the apparatus for information disclosure and transaction processing in a federation chain according to the present disclosure may be applied to other applications requiring transaction processing through information disclosure means, such as government procurement, engineering bidding, etc.
According to an embodiment of the present disclosure, there is provided an apparatus for information disclosure and transaction processing of a federation chain including a first node and a second node, the apparatus including: an information disclosure module that discloses information about the second node in the federation chain based on operation of the first node; and the transaction processing module is used for processing the transaction by adopting the operation mechanism of the alliance chain based on the disclosed information.
As shown in fig. 1, the apparatus 100 for information disclosure and transaction processing of a federation chain according to the present embodiment may include an information disclosure module 101 and a transaction processing module 102. A first node and a second node may be included in the federation chain. Information disclosure module 101 may disclose information about the second node in the federation chain based on the operation of the first node. The transaction processing module 102 may then employ the federation chain's operating mechanism for transaction processing based on the disclosed information.
According to one embodiment of the present disclosure, the first node may have higher operation authority than the second node. Taking a stock exchange platform as an example, according to one embodiment of the present disclosure, the first node may be a selected council node with higher operation authority in an enterprise, and the second node may be a common node with lower operation authority in the enterprise. That is, the information disclosure module 101 may disclose information about the general nodes in the federation chain based on the operation of the council node. The transaction processing module 102 may then employ the federation chain's operating mechanism for transaction processing based on the disclosed information. Here, it should be apparent to those skilled in the art that the council node and the general node are only exemplary, and the present disclosure is not limited thereto. Furthermore, the method is simple. For convenience, the first node may be described as a council node and the second node as a regular node, and as such, it should be clear to one skilled in the art that the present disclosure is not limited thereto, and the council node may also be used as a regular node for disclosure of information, and the council node may also be downgraded to a regular node, and the regular node may also be upgraded to a council node.
According to an embodiment of the present disclosure, the federation chain may further include a third node, and the apparatus for information disclosure and transaction processing for a federation chain may further include a supervision module that supervises the federation chain based on operation of the third node.
As shown in fig. 2, the apparatus 100 may further include a supervision module 103, and the supervision module 103 may supervise the federation chain based on the operation of the third node. The third node may be any supervising authority. For example, according to one embodiment of the disclosure, the third node may be a government department. That is, the supervision module 103 may supervise the federation chain based on the operation of the government department. Here, it should be clear to those skilled in the art that the government department is only exemplary, and the disclosure is not limited thereto.
According to an embodiment of the present disclosure, the information disclosure module may further include: a registration module that registers the second node in the federation chain based on operation of the first node; and a verification module which verifies the information disclosed by the second node based on the operation of the first node aiming at the information disclosure request of the second node.
As shown in fig. 3, the information disclosure module 101 may further include a registration module 1011 and a verification module 1012. The registration module 1011 may register the second node (regular node) in the federation chain based on operation of the first node (council node). Then, the verification module 1012 may verify the public information of the general node based on the operation of the council node with respect to the information disclosure request of the general node. Here, when the council node discloses information as a general node, the verification module 1012 may verify the disclosed information of the council node as the general node based on operations of other council nodes.
According to an embodiment of the present disclosure, the registering module 1011 registering the common node in the federation chain may include receiving registration information from the common node, the registration information including, but not limited to, basic information of a business, share of equity, sales, net profit, net assets, and the like.
Next, the verification module 1012 may verify the registration information received from the general node based on the operation of the council node. The operation of the council node includes, but is not limited to, passing this authentication when most of the council nodes agree to register the common node in the blockchain. In contrast, when most of the council nodes do not agree to register the normal node in the blockchain, then this authentication fails.
According to an embodiment of the present disclosure, the verification module 1012 may verify the information to be disclosed of the general node based on the operation of the council node with respect to the information disclosure request of the general node. The operation of the council node includes but is not limited to passing the verification when most council nodes agree to disclose the information to be disclosed. In contrast, when most of the council nodes do not agree to disclose the information to be disclosed, then this verification fails.
Furthermore, according to an embodiment of the present disclosure, the supervision module 103 may be further configured to supervise verification of the disclosed information of the second node (ordinary node). That is, the supervision module 103 (government department) may be further configured to supervise verification of the public information of the general node.
Specifically, according to an embodiment of the present disclosure, the supervision module 103 supervises the verification of the disclosed information of the common node may include, but is not limited to, the following: in the case where the registered ordinary node registration is successful and the disclosed information is truly valid, a small number of ordinary nodes that do not agree with the registration or a small number of council nodes that do not agree with disclosure of the disclosed information will be penalized. In contrast, in the case of a registration failure of a registered common node or false content of the disclosed information, the majority of common node registrations agreeing to the registration or the majority of council nodes agreeing to disclose the disclosed information will be penalized. Furthermore, normal nodes that disclose false information will also be penalized. Also, if the information disclosed on the blockchain is modified by the disclosed ordinary node, the ordinary node will also be penalized.
According to one embodiment of the present disclosure, the penalty of the supervisor module 103 for a council node or a generic node may be based on a credit score of the council node or the generic node. According to one embodiment of the present disclosure, the supervision module 103 may penalize a council node or a general node based on the following equation (1):
credit score ═ credit score × penalty rate (1).
On the other hand, for example, as described above, in the case where the registration of the registered general node fails or there is false content of the disclosed information, the penalty of the registration of the previous few general nodes not agreeing with the registration or the penalty of the council node not agreeing with the disclosure of the disclosed information will be revoked, except that the majority of the general nodes agreeing with the registration or the majority of the council nodes agreeing with the disclosure of the disclosed information receive the penalty.
According to an embodiment of the present disclosure, the supervision module 103 may revoke the penalty suffered by the council node or the general node based on the following formula (2):
credit score-credit score/penalty rate (2).
According to an embodiment of the present disclosure, the supervision module 103 may be further configured to downgrade the first node operating as the second node to the second node when the trustworthiness score of the first node is less than a predetermined threshold. That is, the supervision module 103 may be further configured to downgrade a council node operating as the normal node to a normal node when the credibility score of the council node is less than a predetermined threshold. Here, it should be apparent to those skilled in the art that the predetermined threshold value may be set according to actual needs or experience of those skilled in the art.
According to one embodiment of the present disclosure, the credibility score of the second node (including the first node as the second node) may be calculated according to the endorsement accuracy rate and the level of credit authority of the second node. For example, poor behavior of endorsement nodes returning inconsistent endorsement results may result in a lower endorsement score. For example, a council node may have higher credits and privileges than a regular node, and thus, the council node has a higher confidence score. In contrast, normal nodes have a lower confidence score.
According to one embodiment of the present disclosure, endorsement accuracy (endorsement score) may be determined by a ratio of the correct endorsement count to the total endorsement count for an endorsement node.
For example, endorsement scoring approaches in accordance with the present disclosure may include, but are not limited to, the following: and if the endorsement node returns a correct endorsement result, adding 1 to the correct endorsement count of the endorsement node, otherwise, adding 1 to the wrong endorsement count.
Then, according to one embodiment of the present disclosure, an endorsement score of an endorsement node may be calculated according to the following formula (3).
Endorsement score is correct endorsement count/total endorsement count (3).
Here, it should be clear to those skilled in the art that such endorsement accuracy calculations are merely exemplary, and the present disclosure is not limited thereto.
According to an embodiment of the present disclosure, the supervision module 103 may be further configured to upgrade the second node to the first node when the credibility score of the second node is greater than a predetermined threshold. That is, the supervision module 103 may be further configured to upgrade the common node to a council node when the credibility score of the common node is greater than a predetermined threshold. Here, it should be apparent to those skilled in the art that the predetermined threshold value may be set according to actual needs or experience of those skilled in the art. Likewise, the credibility score of the second node can be calculated according to the endorsement accuracy rate and the credit authority level of the second node.
According to an embodiment of the present disclosure, the supervision module 103 may be further configured to remove the second node from the federation chain when the trustworthiness score of the second node is less than a predetermined threshold. That is, the supervision module 103 may be further configured to remove the common node from the federation chain when the trustworthiness score of the common node is less than a predetermined threshold. Here, it should be apparent to those skilled in the art that the predetermined threshold value may be set according to actual needs or experience of those skilled in the art. Likewise, the credibility score of the second node can be calculated according to the endorsement accuracy rate and the credit authority level of the second node.
According to an embodiment of the present disclosure, when the supervision module 103 removes from the federation chain a normal node whose trustworthiness score is less than a predetermined threshold, the supervision module 103 may be further configured to remove from the blockchain the chain code of the removed node, and may take the following measures, but not limited to the following measures, to compensate for financial loss of all stakeholders:
the removed business is forced to purchase all stocks from the shareholder based on the current stock price.
If the removed business fails and closes, the remaining assets of the business will be evaluated and sold. The remaining asset revenue for the business will then be refunded to all stakeholders based on the shares held by them.
Furthermore, according to an embodiment of the present disclosure, the information disclosure module 101 may further include an authorization module configured to authorize the first node or the second node to browse the information disclosed by the second node. As shown in fig. 4, the information disclosure module 101 may further include an authorization module 1013. The authorizing module 1013 may be configured to authorize the council node or the regular node or an investor to browse information disclosed by the regular node or the council node as a regular node.
For example, if the common node or the council node as the common node discloses the following information:
information disclosure: reporting: { credit rating: 80, authorizing: [ B, C, D, E ], contents: "encryption (text)" }.
After endorsement, sorting and submission, the published information will be saved on the distributed ledger. If other nodes or investors than the ordinary node disclosing the information need to view the disclosed information, their identities, e.g. their ca (verification authority) certificates, need to be checked.
That is, the other node or investor needs to be authorized by the node to be publicly informed. In this example, only the B, C, D, and E users are authorized. In addition, the credit score (credit rating) of these authorized users needs to be greater than 80 points. Such a user is eligible to view published information only if both conditions, as listed above, are met. Here, it should be apparent to those skilled in the art that the above disclosed information is only exemplary, and the present disclosure is not limited thereto.
According to an embodiment of the present disclosure, the authorization module 1013 may be further configured to receive a request from the first node or the second node to browse information disclosed by the second node. That is, the authorization module 1013 may be further configured to receive a request from the council node or the generic node or an investor to browse information disclosed by the generic node.
According to an embodiment of the present disclosure, the information disclosure module 101 may further include a federation chain deployment module configured to deploy the registered second node in the federation chain based on operation of the first node, and deploy a chain code for the transaction processing module of the second node in the federation chain if the authentication passes.
As shown in fig. 5, the information disclosure module 101 may further include a federation chain deployment module 1014. The federation chain deployment module 1014 may be configured to deploy the registered common node in the federation chain based on operation of the council node, and to deploy the chain code for the transaction processing module 102 for the common node in the federation chain if the authentication passes. Further, according to an embodiment of the present disclosure, when the supervision module 103 removes a normal node with a credibility score less than a predetermined threshold from the federation chain, the federation chain deployment module 1014 may be further configured to remove from the federation chain a chain code related to the removed normal node.
According to an embodiment of the present disclosure, the transaction processing module 102 may further include a recommendation module that recommends a transaction goal for the second node based on the quality of the information disclosed by the second node and the score of the second node.
For example, the transaction processing module 102 may further include a recommendation module. The recommendation module may recommend a trading objective of the common node based on the quality of the information disclosed by the common node and the score of the common node.
According to one embodiment of the disclosure, the quality of the information disclosed by the common node can be represented by the ratio of the number of times the information disclosed by the common node is browsed to the number of times all the information in the federation chain is browsed.
According to an embodiment of the present disclosure, the quality (score) of the information disclosed by the common node may be calculated based on the following equations (4) and (5):
wherein the content of the first and second substances,
according to one embodiment of the present disclosure, the score of the common node may include a credibility score and an asset score of the common node. Here, the general node may be a council node as the general node. Since such a council node operating as a normal node has higher credit and operation authority, it may be set to have an authorization score of 100, while the normal node has an authorization score of 0.
Thus, according to one embodiment of the present disclosure, the credibility score of the common node may be calculated according to the following equation (6):
confidence score-endorsement score × α + authorization score x (1- α) (6).
According to one embodiment of the present disclosure, the recommendation module may recommend a valuable business based on the ratio of the business assets to the sum of all the business assets, i.e., the business' assets score.
For example, an asset score for a business may be calculated according to the following equation (7):
however, an enterprise asset may include the equity of other enterprises that it holds, and thus, according to one embodiment of the present disclosure, an enterprise asset may include both assets that the enterprise itself evaluates and equity assets of other enterprises that it holds. Thus, according to one embodiment of the present disclosure, an enterprise asset may be calculated according to the following equation (8):
enterprise assets are evaluated assets + equity assets (8).
According to one embodiment of the present disclosure, the equity assets of an enterprise may be calculated according to equation (9) below:
wherein, the stock price of the enterprise can be calculated by the following formula (10):
stock price is the asset/share evaluated (10).
According to one embodiment of the present disclosure, the assessed assets of an enterprise may be determined according to sales of the enterprise, net profits of the enterprise, and net assets of the enterprise.
According to one embodiment of the present disclosure, the assessed assets of an enterprise may be calculated according to the following equation (11):
assessed property x α + net profit x β + net property x γ (11)
Thus, according to one embodiment of the present disclosure, the recommendation module may recommend the trading target of the common node (including the council node as a common node) to other businesses or investors based on the investment score calculated by equation (12):
quality score of investment score information α + credibility score β + asset score (1- α - β)
(12)。
Using a federation blockchain-based stock trading platform that does not need to trust each other in accordance with the present disclosure, the problems of trustworthiness and inflexibility of information disclosure and transaction processing based on disclosed information are solved. According to the stock trading platform disclosed by the invention, the enterprise node can disclose invariable enterprise information on the block chain, so that the fairness and credibility of stock trading can be further kept.
Next, an operation flow of the apparatus for information disclosure and transaction processing of a federation chain according to one embodiment of the present disclosure will be described with reference to fig. 6 to 10.
Fig. 6 shows a flow of information disclosure and transaction processing in a blockchain. As shown in fig. 6, first, a general enterprise may be registered in the blockchain through an information disclosure module. The council node may then verify the common enterprise registration through the information disclosure module, and in the event that the council node verifies, the common enterprise may be deployed as a common node to hold a copy of the distributed ledger.
Next, the general node may submit unpublished information such as business news events, equity transfer information, and financial reports, etc. through the information publishing module to attract investors. Then, the council node can verify the undisclosed information through the information disclosure module, and under the condition that the council node verifies, the common node can disclose the information on the blockchain.
Meanwhile, the supervision node can operate to supervise enterprise registration and verification of public information, and penalize adverse behaviors of the council node or the common node, such as disclosure of false information or tampering of a block chain, and the like.
Then, the ordinary enterprise or investor can obtain the recommendation of investment through the transaction processing module based on the information disclosed on the blockchain, and the stock transaction is carried out by adopting the operation mechanism of the blockchain.
Using a federation blockchain-based stock trading platform that does not need to trust each other in accordance with the present disclosure, the problems of trustworthiness and inflexibility of information disclosure and transaction processing based on disclosed information are solved. According to the stock trading platform disclosed by the invention, the enterprise node can disclose invariable enterprise information on the block chain, so that the fairness and credibility of stock trading can be further kept.
Fig. 7 shows a flow of a general enterprise registration on a blockchain. As shown in fig. 7, a general enterprise may submit registration information, which may include basic information of the enterprise, shares, sales, net profits, net assets, etc., to a council node. Next, the council node may verify the registration information (most of the council nodes agree to register, then verify). Thereafter, the business is evaluated and a stock price is set. Next, the council node may deploy a common enterprise as a common node and deploy chain codes for stock trading based on the evaluation model.
Fig. 8 shows an operation flow of the common node disclosure information. As shown in fig. 8, the regular node may submit unpublished company news and other information, etc. to the council node for verification by the council node on the blockchain platform. The verification may include verifying whether the information is of an important type (i.e., information related to stock trading) and verifying authorization of the undisclosed information. If the undisclosed information is validated (majority nodes agree, minority nodes are penalized), the regular nodes can disclose the immutable information to authorized users on the blockchain platform. However, if the undisclosed information is not validated, the ordinary node will be penalized.
Meanwhile, the supervising node may verify the information disclosed by the common node or verify whether the blockchain ledger is modified, for example, based on false information reported by investors or other common nodes. And under the condition that the supervision node verifies that false information exists or the blockchain account book is modified, punishing the common node and the majority council node, and removing the punishment of the minority council node.
Fig. 9 shows a flow of authorization management for information disclosed on a blockchain. As shown in fig. 9, the generic node submits a transaction to an endorsement node (the node that executes the chain code) to disclose information to an authorized user. And then, the endorsement node returns the endorsement result to the common node. Next, after sorting and submission, the published information will be saved on the distributed ledger. However, this published information can only be viewed by authenticated (credit scored and authorized) investors or other common or council nodes. And for an unauthenticated (unauthorized) investor or other common node or council node to submit a browse request to the common node disclosing the information.
Using a federation blockchain-based stock trading platform that does not need to trust each other in accordance with the present disclosure, the problems of trustworthiness and inflexibility of information disclosure and transaction processing based on disclosed information are solved.
