In the prior art, a network administrator, or a management node, may be configured in a federation chain, after the federation chain is established, if a new organization member wants to join the federation chain, an uplink request may be initiated to the network administrator, the network administrator may perform an audit on the uplink request, and after the audit is passed, the network administrator pulls the new organization member into the federation chain, and in the federation chain extension manner, if the network administrator itself is a malicious node (e.g., a node that falsifies information or responds maliciously), or suddenly becomes a malicious node, more malicious nodes may be pulled into the federation chain, which may harm data security of the federation chain, or may not pull in the new organization member normally, and affect extension of the federation chain.

Based on the above-mentioned drawbacks of the related art, the present application provides a method for processing a transaction request, which can overcome the drawbacks of the related art at least to some extent.

Referring to a scene schematic diagram of the present application shown in fig. 1, in a federation chain in the present application, a first federation chain organization and a second federation chain organization exist, and when the first federation chain organization receives a transaction request sent by any federation chain node in the federation chain, after the legitimacy of the transaction request is verified by the first federation chain organization and the second federation chain organization respectively, the second federation chain organization processes the transaction request, so that malicious operation brought to the federation chain when the first federation chain organization has a malicious node condition can be avoided to a certain extent, and data security is ensured.

In the present application, different federation chain nodes may form different federation chain organizations, and the different federation chain organizations form a federation chain, where the federation chain nodes may specifically be different types of devices such as a server device, a physical host, or a User Equipment (UE), and the UE may specifically be a terminal device such as a smart phone, a tablet computer, a notebook computer, a palm computer, a desktop computer, or a Personal Digital Assistant (PDA).

In the federation chain, each federation chain organization may be considered as a whole, or each federation chain may be considered as a cluster device, and thus, in the following description, specific contents of the present application are described for purposes of illustration in terms of federation chain organizations, where in the present application, a federation chain first organization is typically one organization and federation chain second organizations are multiple organizations.

Referring to fig. 2, fig. 2 shows a schematic flow chart of a processing method of a transaction request in the present application, and the processing method of a transaction request provided in the present application may specifically include the following steps:

step S201, a first organization of a alliance chain acquires a transaction request sent by any alliance chain node in the alliance chain;

step S202, if the transaction request is verified to be legal, the first alliance chain organization sends the transaction request to a plurality of second alliance chain organizations;

step S203, if the transaction request is verified to be legal, the plurality of alliance chain second organizations respectively obtain first processing results of the transaction request and respectively send the first processing results to the alliance chain first organizations;

step S204, if the first processing result is verified to be legal, the first organization of the alliance chain obtains a second processing result of the transaction request according to the plurality of first processing results and sends the second processing result to the plurality of second organizations of the alliance chain;

in step S205, if the second processing result is verified to be legal, the plurality of alliance chain second organizations process the transaction request according to the second processing result.

As can be seen from fig. 2, in the present application, any federation chain node may send a transaction request to a federation chain first organization, after the federation chain first organization receives the transaction request and verifies the validity of the transaction request, the federation chain first organization sends the transaction request to a plurality of federation chain second organizations, after the plurality of federation chain second organizations respectively verify the validity of the transaction request, obtains a first processing result of the transaction request, and sends the first processing result to the federation chain first organization, after the federation chain first organization verifies the validity of the received plurality of first processing results, obtains a second processing result of the transaction request according to the plurality of first processing results, and sends a second processing result to the federation chain second organization, after the validity of the second processing result passes the verification, the federation chain second organization processes the transaction request according to the second processing result, in the processing process of the transaction request, on one hand, a consensus mechanism is introduced in a decision stage, namely a final processing result is obtained through the processing results of a plurality of second alliance chain organizations on the transaction request, so that the accuracy of verifying the legality of the transaction request can be improved, and the security risk accompanying the legality of the transaction request which is unilaterally verified by the first alliance chain organization is avoided.

The following proceeds to a detailed description of the various steps shown in fig. 2:

in the present application, the transaction request may be understood to include uplink request, data storage request, data synchronization request, and the like, which require related data transaction.

For example, taking an to-be-uplink organization and an to-be-uplink node as an example, when a certain alliance link node receives a uplink request, a data storage and other transaction requests initiated by the to-be-uplink organization or the to-be-uplink node, the transaction request may be sent to the first alliance link organization, so that the first alliance link organization triggers the processing method of the transaction request provided by the present application.

The to-be-uplink organization or the to-be-uplink node needs to understand that, for an organization or a node which is not uplink or is not added to the alliance chain, a transaction request can be initiated to any alliance chain node or an adjacent alliance chain node, and the alliance chain node which receives the transaction request sends the transaction request to the first organization of the alliance chain to trigger the processing method of the transaction request provided by the application.

In an exemplary implementation, the transaction request referred to in this application may specifically include an uplink request of an organization to be uplink, a downlink request of an organization to be downlink, an update request of logistics state of a logistics item, an update request of a logistics claim state of a logistics item, or an update request of a logistics resource.

It can be understood that, taking the alliance chain applied in the field of logistics as an example, the alliance chain organization in the alliance chain can be various organizations involved in the logistics service, such as a logistics company for carrying out logistics transportation, a financial institution or a bank institution involved in electronic payment in the logistics service, a supply chain company involved in logistics resources, an insurance company involved in logistics claim work, and the like, and various organizations can apply for joining the alliance chain or applying for quitting the alliance chain; or, in the logistics operation, request to upload or download the related logistics state of the logistics, such as the receiving state, the transportation state or the delivery state of the uploaded express; or when the logistics piece is damaged and enters the claim settlement operation, requesting to upload or download the claim settlement state of the corresponding logistics piece, for example, downloading the express delivery piece in the claim settlement operation, specifically including a link of receiving an application, setting up a case, checking and notifying a reimbursement and detailed information of the link; or, in the management process of the logistics resources, the logistics company, the supply chain company, and the financial structure may upload or download the state information of the related logistics resources, taking express delivery as an example, the express delivery resources may specifically include transportation resources such as transportation vehicles, sorting machines, and sorting frames in the transportation link, and may also include various types of resources that may be involved in logistics operations such as various types of human resources, storage resources of various express nodes, information resources, and financial funds.

In yet another exemplary implementation manner, the federation chain first organization and the federation chain second organization in the federation chain may be selected in real time in addition to being pre-selected and configured from the federation chain organizations, so as to prevent the preset federation chain first organization and the preset federation chain second organization from being targeted to the attack, and further reduce the influence of a malicious organization and a malicious node on processing the transaction request.

Correspondingly, when any alliance chain node initiates a transaction request or forwards the transaction request, or when the transaction request is sent to the alliance chain first organization, the alliance chain first organization can be determined in real time.

For example, a list of federation chain organizations may be configured, where organization identifiers and network addresses of the federation chain organizations are recorded in the list, and according to the arrangement order of the federation chain organizations in the organization list and which federation chain organization is the last round of federation chain first organization updated in the list, a federation chain organization in the last round selected as the next order of federation chain organizations of the federation chain first organization may be selected as the current federation chain first organization, or other selection manners may be adopted to select the current federation chain organization in the organization list, and may be adjusted according to actual needs.

In the present application, a random selection is preferably adopted to randomly select one alliance chain organization from alliance chains as the current alliance chain first organization, so as to further reduce the unpredictability of the alliance chain first organization in selection from the random perspective, and thus reduce the possibility that the alliance chain first organization is targeted to attacks.

In order to further reduce the influence caused by the malicious organization and the malicious nodes possibly existing in the second organization of the alliance chain, when the second organization of the alliance chain is selected in real time, the number of the selected second organization of the alliance chain can be enlarged as much as possible.

Preferably, all alliance chain organizations except the alliance chain first organization in the alliance chain can be used as the current alliance chain second organization, in this case, when the alliance chain sends a transaction request to the alliance chain second organization, a broadcasting mode can be adopted, the transaction can be directly broadcast in the alliance chain, compared with a communication mode between alliance chain organizations such as unicast and multicast, the broadcasting mode has the advantage of low communication cost, and the traffic load of the alliance chain first organization can be greatly reduced.

After receiving the transaction request, the first organization in the federation chain verifies the validity of the transaction request, and the verification method may be a verification method adopted by the network administrator in the above-mentioned prior related art to verify the uplink request, or a verification method agreed by the federation chain to any intelligent contract of a node in the federation chain.

After the transaction request passes the verification of the validity at the first organization side of the alliance chain, the transaction request can be sent to the second organization of the alliance chain, and the consensus mechanism of the application is triggered.

It is understood that, similar to the first organization of the federation chain, the second organization of the federation chain may verify the validity of the transaction request by using the above-mentioned verification method employed by the network administrator in the related art to verify the uplink request, or by using any one of the verification methods agreed by the federation chain for any intelligent contract of the nodes of the federation chain.

Every second alliance which receives the transaction request sent by the first alliance can verify the validity of the second alliance to check whether the processing result determined by the first alliance is wrong or even the first alliance is a malicious organization.

After the validity verification, each second alliance can respectively respond to the transaction request, generate a processing result of the transaction request and feed the processing result back to the first alliance, so that the purposes of multi-party verification and multi-party decision are achieved.

After receiving the processing results fed back by the plurality of federation chain second organizations, the federation chain first organization may verify the validity of the processing results, after the processing results are verified to be legal, statistics may be performed, and a final processing result of the transaction request may be obtained on the basis of the statistical results.

In still another exemplary implementation manner, referring to a flowchart of the acquiring process of the second processing result shown in fig. 3, the process of acquiring the second processing result of the transaction request according to the plurality of first processing results by the federation chain first organization, as shown in fig. 3, may include the following steps S301 to S303:

step S301, a first organization of a alliance chain acquires the number of consenting processing results in a plurality of first processing results;

it can be understood that, when the first alliance chain organization receives the first processing result of the transaction request fed back by the second alliance chain organization for the first time, or when the first alliance chain organization receives a preset number of first processing results of the transaction requests fed back by the second alliance chain organization within a preset time, the first alliance chain organization may start to monitor the number of agreement processing results in the received plurality of first processing results, and trigger the following step S302 or step 303 according to the number of agreement processing results in the plurality of first processing results.

Or, the federation chain first organization may count the number of the agreement processing results from the received first processing results when receiving the number of the first processing results of all the federation chain second organizations.

Step S302, if the quantity of the agreement processing results in the preset time meets a quantity threshold, the first organization of the alliance chain generates the agreement processing results of the transaction requests as a second processing result, wherein the numerical value of the quantity threshold is 2f +1, f is the number of Byzantine nodes of the alliance chain, and the quantity of the alliance chain organizations in the alliance chain is larger than 3f + 1;

it can be understood that the byzantine error can be understood as forged information or malicious organization of malicious response, and when the coalition chain overcomes the byzantine error, the number f of byzantine nodes corresponding to the coalition chain can be configured, and the number of the byzantine nodes is the number of the malicious organization allowable by the coalition chain and can be configured in advance.

When the number of agreement processing results in the plurality of first processing results reaches (2 times +1) of the number of Byzantine nodes within the preset time, even if the Byzantine nodes exist in the second organization of the alliance chain, the processing results which are determined integrally can be considered not to be influenced, the error risk is extremely low, and therefore the agreement processing results are generated to serve as the final processing results of the transaction request, namely the second processing results; otherwise, generating a rejection processing result as a second processing result.

In step S303, if the number of the processing results agreed within the preset time is lower than the number threshold, the first organization in the federation generates a processing result of refusing the transaction request as a second processing result.

In order to improve the processing efficiency, the first alliance chain organization can monitor the number of processing agreement results in the first processing results in the process of receiving the first processing fed back by the plurality of second alliance chain organizations, if the number reaches a number threshold value, the processing agreement results can be directly generated at the moment to serve as final second processing results, and the subsequent first processing results sent to the first alliance chain organization can be subjected to neglect processing such as deletion and rejection, so that unnecessary receiving processing and statistical processing are reduced.

After the final processing result, i.e. the second processing result, is obtained, the processing result may be sent to a plurality of federation chain second organizations, so as to synchronize the processing result on the federation chain second organization side.

In the present application, after the first alliance chain organization determines the processing result of the transaction request, the second alliance chain organization may process the transaction request according to the processing result, which is different from the prior related art in which a network administrator unilaterally processes the uplink request.

The second alliance chain organization receiving the processing result sent by the first alliance chain organization can firstly verify the validity of the processing result so as to check whether the processing result determined by the first alliance chain organization is wrong or even whether the possible situation that the first alliance chain organization is a malicious organization occurs, and when the processing result is verified to be legal, the transaction request is processed according to the processing result.

In another exemplary implementation manner, after the validity of the second processing result is verified, the federation chain second organization receiving the second processing result sent by the federation chain first organization may package the transaction request and the organization identifier of the initiating organization of the transaction request according to the second processing result to obtain block information corresponding to the transaction request, and store the block information to complete processing of the transaction request.

For example, taking the transaction request as a uplink request initiated by the to-be-uplink organization as an example, if the second processing result is an approval processing result, and the organization identifier of the initiating organization carried in the uplink request includes an enterprise name, a unified social credit code uscc, a legal identity number id _ card uplink identifier jion, the enterprise name, the unified social credit code uscc, the legal identity number id _ card, and the uplink identifier jion may be encapsulated to obtain block information corresponding to the uplink request, and store and synchronize the block information on configuration block information, for example, the block information may be written into the above-mentioned alliance chain organization list to implement uplink of the to-be-uplink organization and add the block information into an alliance chain.

In another exemplary implementation, referring to another flowchart of the processing method for the transaction request of the present application shown in fig. 4, after obtaining the second processing result, the processing of the certificate may further be included, that is, the following steps S401 to S403 may also be included:

step S401, when the transaction request is an uplink request or a downlink request, the first alliance of the alliance chain also sends a second processing result to the certificate organization in the alliance chain;

it is understood that each organization joining the federation chain may also be configured with a corresponding digital certificate by the certificate organizations in the federation chain to identify the legitimate identity of each federation chain organization in the identity management hierarchy of the federation chain.

Therefore, when the second organization of the federation chain processes the transaction request according to the second processing result, and the to-be-uplink organization performs uplink or downlink on the to-be-downlink organization, the other side can also send the second processing request to the certificate node in the federation chain to trigger the certificate node to perform certificate processing for the to-be-uplink organization or the to-be-downlink organization.

Step S402, the certificate organization decrypts a fifth digital signature of the second processing result by using the threshold signature public key, and verifies whether the decrypted fifth digital signature is legal, wherein the fifth digital signature is synthesized by the first organization of the alliance chain according to a plurality of third digital signatures;

after receiving the second processing result sent by the first alliance chain organization, the certificate organization may also verify the validity of the received second processing result through the threshold signature public key, which may be referred to above specifically and is not described herein again, similarly to the second alliance chain organization.

Step S403, after the second processing result is verified to be legal, the certificate organization issues a new digital certificate for the initiating organization in the certificate list according to the second processing result and the block information, or revokes the digital certificate already issued by the initiating organization in the certificate list.

When the certificate organization processes the certificate of the to-be-uplink organization or the to-be-downlink organization, block information stored by a second organization of a previous federation chain may be specifically referred to, where the block information is obtained by encapsulating an uplink request and an organization identifier of an originating organization thereof, or obtained by encapsulating a downlink request and an organization identifier of an originating organization thereof, and the block information may be stored and synchronized in configuration block information on a link point of a related federation.

When the received second processing result is verified to be legal and block information corresponding to the uplink request or the downlink request is verified to exist, a new digital certificate can be issued to the initiating organization, namely the to-be-uplink organization, in the certificate list, or the digital certificate already issued by the to-be-downlink organization can be revoked.

In another exemplary implementation, the verification of the validity mentioned above may be implemented by a public key and a private key configured in pairs. The public key is called public key (public key), the private key is called private key (private key), and in general, the public key and the private key are contents of an asymmetric encryption algorithm in cryptography, and as the name suggests, the public key can be published, and the private key needs to be safely kept.

In the alliance chain, an initiator of digital information can calculate an abstract locally, then encrypt the abstract through a private key to obtain a digital signature of the digital information, a receiver of the digital information can decrypt the digital signature through a public key corresponding to the private key to obtain an abstract, on the other hand, the receiver of the digital information can calculate another abstract through Hash calculation on the basis of the digital information, and at the moment, if the two abstracts are consistent, due to the uniqueness of a Hash calculation result, the digital information can be considered to be not tampered, forged and pass validity verification in the sending process; on the contrary, if the two digests are inconsistent, the digital information is considered to pass the verification of the validity through tampering and counterfeiting in the sending process.

Correspondingly, the validity verifying part mentioned in the above may specifically include the following:

the first organization of the alliance chain decrypts a first digital signature of the transaction request by using a public key of the initiating organization and verifies whether the decrypted first digital signature is legal or not, wherein the first digital signature is obtained by encrypting the private key of the initiating organization by the initiating organization;

the plurality of alliance chain second organizations respectively decrypt the second digital signature of the transaction request by using the public key of the alliance chain first organization and verify whether the decrypted second digital signature is legal or not, wherein the second digital signature is obtained by encrypting the alliance chain first organization through the private key of the alliance chain first organization;

the first alliance chain organization decrypts the third digital signatures of the first processing results by using the threshold signature public key and verifies whether the decrypted third numbers are legal or not, wherein the third digital signatures are obtained by encrypting the second alliance chain organization through a threshold signature private key;

and the plurality of alliance chain second organizations decrypt the fourth digital signature of the second processing result by using the threshold signature public key and verify whether the decrypted fourth digital signature is legal or not, wherein the fourth digital signature is synthesized by the alliance chain first organization according to the plurality of third digital signatures.

When initiating a transaction request, an initiating organization may also carry a public key of the initiating organization in the transaction request, so that a first organization of a federation chain receiving the transaction request may directly extract the public key from the transaction request, decrypt a digital signature in the received transaction request, and verify the validity of the received transaction request, and of course, the public key of the initiating organization may also be pre-configured, and be synchronized on each organization of the federation chains, for example, a public key list may be configured to record the public keys of each organization of the federation chains;

similarly, when the first organization of the federation chain sends a transaction request to the second organization of the federation chain and runs the consensus mechanism, the first organization of the federation chain encrypts the digital signature of the transaction request by using the private key of the first organization of the federation chain again, and then the second organization of the federation chain decrypts the digital signature by using the public key of the first organization of the federation chain to verify the validity of the transaction request.

If the transaction request is an uplink request initiated by the to-be-uplink organization, the to-be-uplink organization can carry the public key of the to-be-uplink organization in the uplink request, so that the first organization of the alliance chain receiving the first transaction request can verify the validity of the uplink request.

In order to further improve the security of the data, different public and private keys can be used in the consensus stage, and as in the above contents, the first organization in the federation chain sends a transaction request to the second organization in the federation chain, the digital signature can be encrypted by using a common private key, and the second organization in the federation chain feeds back a first processing result of the transaction request to the first organization in the federation chain, the digital signature can be encrypted by using a threshold signature private key. In the subsequent processing stage, the encryption and decryption of the digital signature can be carried out by using the threshold signature public key and the threshold signature private key.

Exemplarily, in the case of the uplink request received by the first alliance chain organization, if the uplink request carries four of the enterprise name of the originating organization, the unified social credit code uscc, the identity number id _ card of the legal person and the uplink identifier jion, the first alliance chain organization may calculate a hash value according to the four of the enterprise name, the unified social credit code uscc, the identity number id _ card of the legal person and the uplink identifier jion to obtain an abstract, decrypt the digital signature of the uplink request by using the public key of the originating organization carried in the uplink request to obtain another abstract, and pass validity verification if the two abstracts are consistent;

the first organization of the alliance chain continuously encrypts the abstract by using the private key of the first organization of the alliance chain to obtain a new digital signature, obtains an uplink request with the new digital signature, and sends the uplink request to a plurality of second organizations of the alliance chain. Similarly, the second organization of the alliance chain calculates the hash value according to the name of the enterprise carried in the uplink request, the unified social credit code uscc, the identity number id _ card of the legal person and the uplink identification jion to obtain an abstract, decrypts the digital signature of the uplink request by using the public key of the first organization of the alliance chain to obtain another abstract, and passes the validity verification if the two abstracts are consistent.

Each alliance chain second organization can respectively respond to the uplink request which passes the verification to generate a processing result of the uplink request and feed the processing result back to the alliance chain first organization, so that the purposes of multi-party verification and multi-party decision are achieved, wherein each alliance chain second organization carries out hash operation on the processing result to obtain a summary, and encrypts the summary by using a threshold signature private key to obtain a digital signature (or a threshold signature) of the processing result;

when a first alliance chain organization receives a first processing result of agreement processing results sent by a plurality of second alliance chain organizations, a threshold value of 2f +1 is obtained, a final unified processing result can be generated and used as a second processing result, the second processing result is subjected to hash operation to obtain a summary, and the summary is encrypted by using a threshold signature private key to obtain a digital signature (or another threshold signature) of the second processing result. And a second organization of the alliance chain receiving the second processing result calculates a hash value according to the enterprise name, the unified social credit code uscc, the identity card number id _ card of the legal person and the uplink identification jion carried by the second processing result to obtain an abstract, decrypts the digital signature of the second processing result by using a threshold signature public key to obtain another abstract, if the two abstracts are consistent, passes the validity verification, processes the uplink request according to the second processing result, and draws the organization with the uplink to the alliance for uplink.

The federation chain first organization may specifically combine the digital signatures with a threshold signature private key of the first organization to encrypt a digest obtained by performing hash calculation on the second digital result to obtain a digital signature, and synthesize a new digital signature as the digital signature of the second processing result, so that the digital signature corresponds to the federation chain second organizations and the federation chain first organization and may be decrypted by a corresponding threshold signature public key, and the pre-door signature public key may be directly carried in the second processing result sent by the federation chain first organization to the federation chain second organization, or may also be pre-configured, and is synchronized on each federation chain organization in the federation chain, for example, configured in a public key list.

In the process, each second organization in the federation chain uses a threshold signature private key of the second organization, encrypts a digital signature of the first processing result, the second organization of the federation chain can adopt a threshold signature public key to decrypt different digital signatures of the first processing result fed back by the second organization of the federation chain, compared with the method of using the private key and the public key of each second organization of the federation chain to encrypt and encrypt the digital signature, when the first organization of the alliance chain is processed, because the public digital signature which can decrypt the encrypted digital signature of the private keys of different threshold signatures is adopted, the calling process of the public key can be obviously reduced, therefore, in the decryption process, the decryption efficiency can be obviously improved, the response time of the recognition mechanism in the application can be obviously improved, and the processing efficiency of the transaction request can be finally improved, which is very beneficial to processing the transaction request by the alliance chain.

In order to better implement the processing method of the transaction request provided by the application, the application also provides a processing device of the transaction request.
