Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Example one

The embodiment of the invention provides a service processing method applied to node equipment in a block chain network. Fig. 3 is a schematic flowchart of a service processing method based on a block chain according to a first embodiment of the present invention; as shown in fig. 3, the method includes:

step 301: receiving an order relation service access request sent by client equipment through an interface provided by a blockchain; wherein, the subscription relation service access request carries an identity authentication certificate.

Here, the client device is installed with a blockchain client, and the interface provided by the blockchain is provided by the blockchain client and is an independent application.

Here, the client device may be a device located at a mobile provincial company or a mobile branch company or a third party service platform side.

That is, on provincial companies, branch companies, and third party platforms, blockchain clients are deployed. The blockchain client may be deployed separately and provide an application programming interface, such as a REST API, to the outside, or may be integrated into an provincial corporate application.

Here, REST, an abbreviation of Representational State Transfer, means "presentation layer State conversion" by direct translation, which is an api (application Programming interface) design concept of internet applications.

Optionally, the identity authentication certificate carries user right information.

Here, the authentication Certificate is uniformly issued by a Certificate Authority (CA) Server (Server); the issued objects include, but are not limited to, provincial companies, platforms, and third parties.

For example, the subscription relationship service access request may be to view transaction data of a certain platform.

Here, the subscription relationship service includes, but is not limited to, a large circle type transaction, a store-and-forward type transaction.

Here, the large circle type transaction can be understood as a transaction of a type in which a service request and a service response are provided on a service.

Here, the store-and-forward transaction may be understood as that a service initiator sends a service request to a mesh network system, and the mesh network system immediately responds to a response message and indicates that the request is received after completing operations such as message verification. At which point the transaction is considered to be successfully completed by the service originator. The mesh network system is responsible for successfully forwarding the service request to the corresponding home party for processing.

Step 302: and verifying the authority of the identity authentication certificate based on the intelligent contract, and determining whether the client equipment is allowed to operate the data in the subscription relation service which the client equipment requests to access according to a verification result.

Wherein the subscription relationship service is implemented by an intelligent contract.

Because the order relation service in the block chain service network is realized by the intelligent contract, the corresponding authority in the identity authentication certificate can be verified in the intelligent contract, and whether the corresponding data can be operated or not is determined.

For example, the client device a sends a subscription relationship service access request a to the node device through an interface provided by the blockchain; the subscription relation service access request a is used for representing a subscription relation service accessing the client device B, and the subscription relation service access request a carries an identity authentication certificate a1 of the client device a; the node device verifies the authority of the authentication certificate a1 based on the smart contract, and determines whether to allow the client device a to operate the data of the subscription relationship service of the client device B which it requests to access, according to the verification result. If the client device A has the authority to access the data of the subscription relationship service of the client device B, the node device determines to permit the client device A to operate the data of the subscription relationship service of the client device B which the node device requests to access based on the smart contract. If the client device A does not have the authority to access the data of the subscription relationship service of the client device B, the node device determines the data of the subscription relationship service of the client device B which cannot be accessed by the client device A based on the intelligent contract.

That is, the client device may request access to the subscription relationship data of other client devices from the node device, specifically whether to permit the request to be determined by the node device based on the smart contract.

For another example, the client device a sends a subscription relationship service access request a to the node device through an interface provided by the blockchain; the subscription relation service access request a is used for representing a subscription relation service accessing the client device a, and the subscription relation service access request a carries an identity authentication certificate a1 of the client device a; the node device verifies the authority of the authentication certificate a1 based on the smart contract, and determines whether to allow the client device a to operate the data of the subscription relationship service of the client device a which the node device has requested access, according to the verification result.

That is, the client device may apply to the node device for access to its subscription relationship data.

Typically, there are several provincial companies and several platforms in a blockchain network. The transaction between province company and platform, not intended to be seen by other provinces, can now be achieved by the following steps:

1. when an identity authentication certificate is issued, corresponding user permission information is added to the certificate;

2. when provincial companies, platforms and third parties use the blockchain client to access the order relation service in the blockchain service network, the identity authentication certificate of the provincial companies, the platforms and the third parties needs to be used; if the identity authentication certificate does not exist, the blockchain client cannot be started normally, and the blockchain service network cannot be accessed normally;

3. because the order relation service in the block chain service network is realized by the intelligent contract, the corresponding authority in the identity authentication certificate can be verified in the intelligent contract, and whether the corresponding data can be operated or not is determined.

By adopting the technical scheme of the embodiment of the invention, the data of the ordering relationship is stored through the block chain, the problem of inconsistent data in all scenes of the ordering relationship can be solved, and the expandability is strong.

In this embodiment, the process of storing the order relationship data in the blockchain network includes:

step 303 (not shown in the figures): the node device receives a create transaction proposal request sent by the client device.

Step 304 (not shown in the figures): the node equipment executes simulated transaction to the transaction proposal creating request based on the intelligent contract, and returns a corresponding proposal execution result to the client equipment, so that the feasibility verification is performed on the proposal execution result fed back by each node equipment by the client equipment according to the endorsement policy.

Here, the node devices described in steps 303 and 304 may be understood as endorsement nodes.

Here, the feasibility verification may be understood as validity verification.

Here, the client application needs to verify the proposal execution result according to the endorsement policy. For example, the endorsement policy may be set to: if the proposal execution results returned by y% endorsement nodes are consistent, the transaction is considered to be submittable, i.e. the transaction is confirmed to be legal. For example, y is greater than a certain value, such as y 51.

In the foregoing scheme, optionally, the method further includes:

step 305 (not shown in the figure): the node equipment receives a transaction which is sent by the client equipment and corresponds to the transaction proposal creating request; wherein the transaction is sent by the client device after the feasibility verification is passed.

Specifically, after verifying that the proposal result is legal, the client device submits the transaction to a ranking service in the blockchain network, so that the ranking service ranks the transaction.

Generally, after the ranking service successfully receives the transaction, a notification is returned to the client device that the transaction has been submitted.

Here, if the client device does not need to return a subsequent verification result notification, it may complete its own business process after receiving the notification that the transaction has been submitted.

Step 306 (not shown in the figures): the node device distributes the transaction to node devices in a blockchain network for verification of the transaction by the node devices.

Optionally, before distributing the transaction to a node device in a blockchain network, the method further includes:

ranking the transactions by a ranking service in a blockchain network;

the ordering service packs the transaction into a block based on the ordering result to distribute the block containing the transaction to node devices in a blockchain network.

Step 307 (not shown in the figure): and after the verification is passed, the node equipment adds the ordering relation data corresponding to the transaction into the blockchain network.

Step 308 (not shown in the figures): and the node equipment returns a verification result notice to the client equipment connected with the node equipment.

For example, a transaction d sent by the client device a, the node device 1 completes verification, stores the order relationship data corresponding to the transaction d into the node device 1, and notifies the client device a at the same time; after the verification is completed, the node device 2 stores the order relation data corresponding to the transaction d into the node device 2, and notifies the client device a.

Here, the node device described in steps 305 to 308 may be understood as a commit node.

Thus, the above flow shows a normal processing flow of the order relation transaction when no abnormality occurs in the blockchain, and the following description is further specifically given.

Specifically, the normal processing flow of the subscription relationship transaction when no exception occurs in the blockchain may include:

1. the application creates a transaction proposal through the blockchain client and sends the proposal to an endorsement node in the blockchain network. The number of endorsement nodes will vary depending on the service features. The block chain service network can flexibly define the endorsement strategy. 2. The endorsement node executes the intelligent contract, namely, performs the simulated transaction; and the execution result of the intelligent contract is contained in the proposal result and returned to the block chain client. The transaction performed at this step is not actually written to the database. 3. And the block chain client collects the proposal results of all endorsement nodes and verifies the proposal results. The client application program needs to verify the proposal result according to the endorsement policy. For example: it can be set that 60% of the endorsement nodes return the same proposal result, and the transaction is considered to be submittable. 4. After the client application program verifies that the proposal is legal, the client submits the transaction to a sequencing service in the blockchain network to sequence the transaction. After the ordering service successfully receives the transaction, the blockchain client receives a notification that the transaction has been submitted. If the application program does not need to return the verification result, the service processing of the application program can be completed after the notification is received. 5. The ordering service packages received transactions in batches into tiles and distributes them to commit nodes in a blockchain network. Normally, all nodes in a blockchain network are commit nodes. 6. And after the submitting node receives the block, performing transaction verification. After verification is complete, the block is added to the blockchain. And notifies the blockchain client connected to the current node of the verification result. 7. And when the client receives the notification event, performing corresponding business processing according to the verification result of the transaction.

Further optionally, the method further comprises:

Here, the cause of the data loss may be a disk damage.

Therefore, an exception handling process of the order relation transaction when the block chain is abnormal is provided.

It should be noted that, in this embodiment, after the blockchain scheme is used, the transaction flows of the large circle type transaction and the store-and-forward type transaction are consistent. The block chain client can realize synchronous calling, asynchronous calling and calling without returning results by setting different parameters. Therefore, large circle class and store-and-forward class transaction are not distinguished any more, and can be collectively called as a blockchain ordering relationship transaction flow.

By adopting the technical scheme of the embodiment of the invention, the problem of inconsistent data in all scenes of the ordering relationship can be solved, and the expandability is strong. Specifically, the block chain stores the ordering relationship data, so that the ordering relationship data consistency of each node can be guaranteed; different nodes process different types of transactions, the functions of all nodes are different, and the multi-channel technology is utilized to realize physical isolation of different service data; realizing data authority control by using an access control strategy; the intelligent contract technology ensures that the service processing programs of all the nodes are the same, realizes the standardization of the service process and avoids the problem of inconsistent data caused by different service processing programs.

Example two

The embodiment of the invention provides a service processing method applied to client equipment in a block chain network. Fig. 4 is a flowchart illustrating a service processing method based on a block chain according to a second embodiment of the present invention; as shown in fig. 4, the method includes:

step 401: sending an order relation service access request to node equipment in a blockchain network through an interface provided by a blockchain, verifying the authority of the identity authentication certificate by the node equipment based on an intelligent contract, and determining whether to allow the client equipment to operate data in the order relation service which the client equipment requests to access according to a verification result; wherein, the subscription relation service access request carries an identity authentication certificate.

Step 402: and receiving a response result of the subscription relationship service access request returned by the node equipment.

In the foregoing scheme, optionally, the method further includes:

the method comprises the steps that client equipment sends a transaction proposal creating request to node equipment in a block chain network, and each node equipment executes simulated transaction on the transaction proposal creating request based on an intelligent contract;

the client equipment receives a proposal execution result returned by each node equipment;

the client equipment carries out feasibility verification on the proposal execution result fed back by each node equipment according to the endorsement strategy;

wherein the node device can be understood as an endorsement node.

In the foregoing scheme, optionally, the method further includes:

after the feasibility verification is passed through by the transaction proposal creating request, the client equipment sends a transaction corresponding to the transaction proposal creating request so as to verify the transaction by the node equipment, and after the verification is passed, the ordering relation data corresponding to the transaction is added into the blockchain network;

the client equipment receives a check result notification returned by the node equipment;

wherein the node device may be understood as a submitting node.

Specifically, the sending the transaction corresponding to the request for creating the transaction proposal includes:

the client device submits a transaction proposal corresponding to the transaction proposal creation request to a sorting service in the blockchain network so as to sort the transactions by the sorting service, and packages the transactions into a block based on a sorting result so as to distribute the block containing the transactions to node devices in the blockchain network;

wherein the node device may be understood as a submitting node.

Further, upon successful receipt of the transaction by the ranking service, a notification is returned to the client device that the transaction was submitted. Here, if the blockchain client does not need to return a subsequent check result, it can complete its own service processing after receiving the notification.

Specifically, the ordering service orders the transaction proposals, packs the transaction proposals into a block based on an ordering result, and distributes the block to a submission node in a block chain network, so that the submission node checks order relationship data corresponding to each transaction proposal in the block; after the submitting node receives the (block), transaction verification is carried out. After the verification is completed, (blocks) are added into the block chain, and the verification result is informed to the block chain client connected to the current node.

In the foregoing scheme, optionally, the method further includes:

Wherein processing transactions that occur during the downtime comprises:

Thus, the above flow gives the processing flow of the client when the block chain is abnormal.

Specifically, after the client sends the transaction, the client is down before receiving the response, and the blockchain client provides a relatively perfect fault recovery capability, and the method has the following aspects:

after the application is recovered, transactions that occurred during the failure need to be processed. This requirement is most common, and the blockchain client needs to record the latest height of the block (i.e. the number of processed blocks) that has been processed by itself, and after the application program is recovered, set the transaction that has occurred at the network level of the blockchain from this height;

after the application is recovered, the transaction occurring in the designated interval needs to be processed.

Further, the client device is further configured to send a transaction proposal creation request to node devices in the blockchain network, so that each node device executes a simulated transaction on the transaction proposal creation request based on an intelligent contract; the node equipment is also used for receiving a transaction proposal creation request sent by the client equipment; executing a simulated transaction on the create transaction proposal request based on a smart contract; and returning a corresponding proposal execution result to the client equipment, so that the client equipment performs feasibility verification on the proposal execution result fed back by each node equipment according to the endorsement policy.

Further, the client device is further configured to send a transaction corresponding to the transaction proposal creation request after the transaction proposal creation request passes feasibility verification, so that the node device verifies the transaction, and add the subscription relationship data corresponding to the transaction into the blockchain network after the verification passes; receiving a check result notification returned by the node equipment; the node equipment is also used for receiving the transaction which is sent by the client equipment and corresponds to the request for establishing the transaction proposal; wherein the transaction is sent by the client device after passing the feasibility verification; distributing the transaction to a node device in a blockchain network for verification of the transaction by the node device; and after the verification is passed, adding the ordering relation data corresponding to the transaction into the blockchain network.

In practical applications, there are multiple mobile provincial companies, multiple mobile branch companies and multiple third party platforms in a blockchain network. The block chain service system stores the ordering relation data in a block chain network, realizes the service of the ordering relation through an intelligent contract, provides an access interface for the outside, and operates the ordering relation service through the interface provided by the block chain in a unified way by the mobile province company, the mobile branch company and the third-party platform. For example, mobile provincial companies, mobile affiliates, and third party platforms unify access to subscription relationship data through interfaces provided by blockchains. The block chain service system utilizes a distributed consensus mechanism and a gossip protocol to ensure the data consistency among different nodes in a block chain network. Fig. 7 is a schematic flow chart illustrating a subscription relationship in a blockchain network according to an embodiment of the present invention, and as shown in fig. 7, transactions between a BOSS platform or a service platform and a blockchain node are independent from each other. The BOSS platform or the service platform sends a transaction request to the block chain nodes, and the block chain nodes respond to a transaction result based on the intelligent contract and the ordering relation data; and returns a transaction result notice to the BOSS platform or the service platform.

After the business processing system described in this embodiment uses the block chain scheme, the transaction flows of the large circle type transaction and the store-and-forward type transaction are consistent. The block chain client can realize synchronous calling, asynchronous calling and calling without returning results by setting different parameters. Therefore, large circle type and store-and-forward type transaction are not distinguished any more, and are unified into a block chain ordering relationship transaction flow.

Here, the large circle type transaction refers to a transaction having a service request and a service response type on a service.

Here, the store-and-forward transaction means that a service initiator sends a service request to a mesh network system, and the mesh network system immediately responds to a response message and indicates that the request is received after completing operations such as message verification and the like. At which point the transaction is considered to be successfully completed by the service originator. The mesh network system is responsible for successfully forwarding the service request to the corresponding home party for processing.

When a mobile province company, a mobile branch company and a third-party platform use a block chain client to access an order relation service in a block chain service network, the mobile province company, the mobile branch company and the third-party platform must use an identity authentication certificate of the mobile province company, and the identity authentication certificate adds corresponding user authority information. If there is no authentication certificate, the blockchain client cannot be started normally, and thus cannot access the blockchain service network normally. Because the order relation service in the block chain service network is realized by the intelligent contract, the corresponding authority in the identity authentication certificate can be verified in the intelligent contract, and whether the corresponding data can be operated or not is determined.

The business processing system of the embodiment of the invention can solve the problem of inconsistent data in all scenes of the ordering relationship.
