Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Example one

Fig. 1 is a flowchart of a method for processing blockchain data according to an embodiment of the present invention, where the method is applicable to a situation where when a blockchain network processes a transaction request including a to-be-published message, attribute information of the to-be-published message and a link result of the to-be-published message are recorded, so that transaction data can be conveniently obtained based on the link result when the transaction data is obtained.

As shown in fig. 1, the method of this embodiment includes:

s110, sending the transaction request containing the message to be issued to the blockchain network so that the blockchain network processes the transaction request and stores the uplink of the transaction data containing the message to be issued.

It should be noted that the technical solution of this embodiment may be executed by any blockchain node in the blockchain network, and the blockchain node executing the technical solution of this embodiment may be used as a message producer node. The message producer node is the node issuing the message in the block chain network. Wherein the transaction request sent to the blockchain network is a signed transaction request. Each message to be published has topic information corresponding to the message to be published. The topic information corresponding to different messages to be published is determined, and can be determined according to a certain rule. For example, transactions with the same data structure may be attributed to the same topic, which may be denoted as topicX, with X denoting the number of the topic. The blockchain network is configured to receive the transaction request, process the transaction data corresponding to the transaction request, and uplink store the processed transaction data, that is, store the processed transaction data in the blockchain network.

Specifically, the message producer node may send a signed transaction request containing the message to be published to the blockchain network. After receiving the transaction request, the blockchain network can check the transaction request, process the transaction data when the check passes to obtain processed transaction data, and uplink-store the processed transaction data containing the message to be issued.

S120, receiving the uplink result fed back by the block chain network, and correspondingly storing the block identifier of the block where the transaction data is located in the uplink result and the theme information.

After the blockchain network receives the transaction request, the transaction request can be checked, and the transaction data including the message to be issued is uplink-stored when the check is passed.

In order for the message producer node to determine the location of the block where the transaction data is located, the uplink timestamp, and other information, the uplink result may be fed back to the message producer node. The uplink result may include a block identifier of a block in which the transaction data is located, and may also include information such as a timestamp of uplink.

Specifically, the message producer node receives the uplink result fed back by the block chain network, and obtains the block identifier storing the transaction data in the uplink result. In order to facilitate subsequent acquisition of the message to be issued, the uplink result, i.e., the block identifier, may be stored in correspondence with the topic information.

S130, the topic information corresponding to the message to be published and the identification information of the message producer node are sent to a block chain network, so that the block chain nodes in the block chain network correspondingly store the topic information and the identification information, and the block chain nodes subscribing the topic information can query the message to be published from the block corresponding to the block identification after acquiring the block identification from the message producer node according to the identification information.

The identification information is the unique identification of the block chain node. For example, each node in the blockchain network may be labeled 1, 2, 3 …, respectively, which may be identification information of a blockchain link point. Of course, each block chain node may be marked in other manners, and only one block chain node may be determined according to the marking.

Specifically, when a transaction request including a message to be published is sent to the blockchain network, the subject information of the message to be published and the identification information of the message production node may be sent to other blockchain nodes in the blockchain network, and the unique identification and the subject information of the message production node are stored as a set of pairs in the blockchain nodes.

The advantage of the arrangement is that when a block chain node subscribing to certain topic information in the block chain network acquires transaction data from the block chain network, the identification information corresponding to the subscribed topic information can be determined according to the topic information and the identification information stored in the node, and then the block chain node corresponding to the identification information can be found, so that the transaction data corresponding to the subscribed topic information can be acquired from the block chain node, thereby avoiding the technical problem of low efficiency and resource waste caused by traversing each block in the block chain network when acquiring the transaction data, and improving the technical effect of convenience for acquiring the transaction data from the block chain.

That is, after the message producer node issues the message, the event message service component pair in the node acquires topic information of the message and stores the topic information in a chain in the event. After the transaction request is processed, a uplink result may be returned, and the uplink result may include an event ID, which may be an identifier of a block where the transaction data is located, and based on the block identifier, uplink verification and tracking may be performed. The information such as the publishing time and the block identification of the message to be published. The common node is used for processing the received transaction request and uplink storing the processing result.

It should be noted that, in order to enable the message producer node to locally store the subject information of the message to be published, and send the subject information of the message to be published and the identification information of the producer node to other blockchain nodes in the blockchain network, a message service component, that is, an event component, may be deployed in each blockchain node in the blockchain network in advance. Referring to fig. 2, a message service component is installed at each peer node in the blockchain network. Of course, each blockchain node may be a message producer node, or may be a message acquirer node, i.e., a node that acquires transaction data.

Therefore, before sending the transaction request containing the message to be issued to the blockchain network, the method further comprises the following steps: the message service components are deployed in each node of the block chain network, so that the subject information corresponding to the message to be issued and the identification information of the producer node are sent to the block chain network based on the message service components; the message service components are deployed with associated intelligent contracts of the message service components, so that the subject information of the messages to be issued is determined based on the associated intelligent contracts.

When the message producer node issues the message, the message service component deployed in the message producer node can process the message and send the processing result, optionally the subject information corresponding to the message, to other block chain nodes in the block chain network. The associated intelligent contract corresponds to the message service component and is used for determining a processing mode, a sending mode and the like of the message to be issued, and the associated intelligent contract can be modified according to actual requirements. Subject information of the message to be published may be determined based on the associated smart contracts.

The advantage of deploying the message service component in the block chain link point is that the message service component can still process the message to be published while sending the message to be published to the block chain network, so as to obtain the subject information of the message to be published. And the theme information and the corresponding block chain link point identification information are sent to the block chain nodes based on the message service component, so that the technical effect of traceable data uplink is achieved.

In this embodiment, deploying the message service component in each node in the blockchain network includes: signing the associated intelligent contract by adopting a first block chain key of the block chain node to obtain a first data signature of the associated intelligent contract; and sending the first data signature to the block chain nodes in the block chain network to indicate other nodes to check the first data signature, and installing associated intelligent contracts in each node in the block chain network when the check is detected to pass.

That is to say, when each blockchain node in the blockchain network deploys the message service component, the associated intelligent contract may be signed first to obtain a first data signature; and when the signature check passes, a related intelligent contract can be installed in the block chain network so as to send the message to be issued to the block chain node based on the related intelligent contract, thereby improving the technical effects of convenience and high efficiency of acquiring the transaction data from the block chain network.

It should be noted that, the message service component deployed in the node may complete the transmission notification of the message topic information, store the uplink result, and obtain and uplink store the consumption result, thereby improving the traceability and traceability of data.

For a clear understanding of the deployment of message service components in block chain nodes, see fig. 3. Illustratively, each node in the blockchain network may be labeled as node 1, node 2, node 3, etc., with the consensus node generating a node for the blockchain. And deploying a message service component in the node 1, signing the associated intelligent contract in the message service component, and sending a signature result to the block chain network, namely submitting the installation event contract transaction to the consensus node. And a block generation node of the block chain network, namely a common identification node, receives the signature result, namely the transaction, and verifies the signature, namely the signature is verified, so as to determine whether the transaction is tampered in the transmission process. If the check and sign pass and the node 1 has the authority to install the intelligent contract, consensus can be achieved, namely the event component can be installed. The result can be fed back to the node 1, the node 1 successfully installs the message service component, and the message component also deploys the associated intelligent contract. Based on the associated intelligent contract, the subject information of the message to be issued can be acquired, and the subject information and the node identification information of the message to be issued are sent to other block chain nodes. Certainly, if the signature verification fails or the node does not have the authority to deploy the associated intelligent contract, the associated intelligent contract of the message service component fails to be deployed, and at this time, the theme of the message to be published and the identification information of the node and the like sent by the message publishing node cannot be received. Other nodes in the blockchain network can install the message service component in the node according to the mode so as to achieve convenience of acquiring the transaction data.

Example two

Fig. 4 is a schematic flow chart of a block chain data processing method according to an embodiment of the present invention, where the method is applicable to a situation where corresponding transaction data is acquired from a block chain network based on message topic information subscribed by a message acquirer node, and the method may be executed by a block chain data processing apparatus, where the apparatus may be implemented in a form of software and/or hardware, and the hardware may be a server or an electronic device. As shown in fig. 4, the method of this embodiment includes:

s410, according to the topic information subscribed by the message acquirer node, determining the identification information of the block chain node corresponding to the topic information.

It should be noted that the message acquirer node may be any blockchain node in the blockchain network. That is, any node in the blockchain network may serve as both a message acquirer node and a message producer node, and each node may be defined as a message producer node or a message acquirer node according to specific service requirements.

For clarity, any node in the blockchain network may be introduced as a message acquirer node in the technical solution of the embodiment of the present invention.

Wherein, the message acquirer node can understand the node which needs to acquire the transaction data stored in uplink in the blockchain network. The message acquirer node may preset theme information to be monitored, that is, the theme information subscribed by the message acquirer, so as to quickly acquire the transaction data corresponding to the theme based on the monitored theme information. If the message issued by a certain blockchain node includes the subject information, the node identifier corresponding to the blockchain is the identifier information corresponding to the subject information, that is, the identifier information is the unique identifier of the blockchain node.

Specifically, according to the topic information subscribed by the message acquirer node, the identification information of the block chain node corresponding to the topic information may be determined, so as to find the corresponding block chain node based on the identification information.

Illustratively, topic information subscribed by the message acquirer node is topic1, and when acquiring transaction data corresponding to topic1, topic information and block link point identification corresponding to subscribed topic information topic1 may be determined according to topic information and corresponding block link point identification stored by the consumer node, so as to acquire transaction data corresponding to subscribed topic information based on the block link point identification.

S420, sending request information for acquiring the block identifier corresponding to the subject information to the block link point corresponding to the identification information, so that the block link point determines the block identifier corresponding to the request information based on the request information.

The block identifier may be a unique identifier of a block in which the transaction data is located. Specifically, according to the identification information, the block link point corresponding to the identification information may be determined, for example, the identification information is 1, the corresponding block link node is node 1, and if the obtained identification information is 1, the block link point corresponding to the identification information 1 may be determined to be node 1. From the topic information stored in the block link point and the block identifier of the block in which the transaction data is located, the block identifier corresponding to the topic information subscribed by the message acquirer can be determined, so that the transaction data containing the message to be published can be acquired from the corresponding block based on the block identifier.

It should be noted that, if the block link point is determined based on the identification information, it indicates that the block link point distributes the message of the subject information, and also stores the uplink result of the transaction data corresponding to the subject information, that is, the block identification of the block where the transaction data including the message to be distributed is located. Therefore, the block identifier where the transaction data corresponding to the subject information is stored can be acquired according to the subject information of the message acquirer node, and the transaction data including the message to be distributed is acquired based on the block identifier, so that the convenience of acquiring the transaction data is improved.

Optionally, before determining, according to the topic information subscribed by the message acquirer, identification information of a block chain node corresponding to the topic information, the method further includes: and deploying the message service components in each node in the block chain network so as to receive and store the theme information and the identification information of the corresponding block chain link point sent by the block chain network based on the message service components.

The message service components are deployed in the block chain nodes, and the subject information of the information to be issued and the corresponding block chain node identifiers sent by other block chain nodes can be recorded based on the message service components.

Specifically, based on the topic information published by other block chain nodes and the identification information of the corresponding block chain node stored in the message service component, the identification information of the other block chain nodes corresponding to the topic information subscribed by the message acquirer can be acquired, so that the transaction data corresponding to the topic information is acquired from the block chain, and the technical effects of convenience and high efficiency in acquiring the transaction data are improved.

S430, receiving the block identification fed back by the block link point, generating a transaction request for acquiring the transaction data according to the block identification, and sending the transaction request to the block chain network so as to acquire the transaction data corresponding to the transaction request from the block chain network.

Specifically, after the message acquirer node receives the block identifier fed back by the block link node, a transaction request for acquiring transaction data, which is sent to the block link network, may be generated based on the block identifier, and the generated transaction request is sent to the block link network, so that the block link network acquires the transaction data including the message to be issued from the corresponding block based on the block identifier in the transaction request.

In this embodiment, the blockchain network may feed back the transaction data to the message acquirer node, and after the message acquirer node receives the transaction data, the message acquirer node may perform signature verification on the transaction data, and if the signature verification passes, the transaction data may be processed, that is, the transaction data may be used. After the processing is finished, the processing result and the node identifier of the message acquirer node can be fed back to the block link network, so that the block link node providing the message subject in the block link network stores the data processing result and the identifier information of the message acquirer node using the transaction data, and meanwhile, the processing result is stored in a transaction component in the message acquirer node, thereby facilitating the tracking and verification of the transaction data. The processing result may include the processing time, the identifier of the message acquirer node, whether the processing is successful, and the like. The method has the advantages that the block chain nodes can determine the message acquirer nodes and the transaction data processing results, so that the transaction data can be conveniently tracked and verified, and the traceability of the data is improved.

It should be noted that, since each blockchain node in the blockchain network is deployed with a message service component, and each service component is deployed with an associated intelligent contract, after the blockchain node receives the processing result and the identification information of the message acquirer node, the result can be linked and stored, thereby facilitating tracking and verifying the transaction data.

It should be further noted that, the message service component in the message acquirer node may be configured with the number of times of processing, and if the message acquirer node fails to process the transaction data, the transaction data may be continuously processed. If the processing times exceed the configured times and are unsuccessful, the processing result is still fed back to the block chain node issuing the subject information, and the processing result is further stored on the message service component in the block chain node, so that data can be tracked according to corresponding information in the follow-up process.

According to the technical scheme of the embodiment of the invention, the identification information of the block chain node corresponding to the subject information can be determined according to the subject information subscribed by the consumer node, and the corresponding block chain node can be found based on the identification information, so that the block identification of the transaction data corresponding to the subject information is determined, and further the corresponding transaction data is obtained based on the block identification, and the technical effect of improving the convenience of obtaining the transaction data is improved.

EXAMPLE III

Fig. 5 is a flowchart illustrating a block chain data processing method according to a third embodiment of the present invention. For clear understanding of the technical solution of the embodiment of the present invention, the solution can be understood from the perspective of interaction between a message producer node and a message acquirer node in a blockchain network. Wherein, the same or similar nouns or terms as above are not repeated herein.

As shown in fig. 5, the method includes:

s501, the message production side node sends a transaction request containing the message to be issued to the block chain network, so that the block chain network processes the transaction request and stores the transaction data containing the message to be issued in an uplink manner.

Specifically, the message producer node sends request information of the transaction data uplink to the blockchain network, and the blockchain network can process the transaction data based on the request information and store the transaction data uplink including the message to be issued.

S502, receiving the uplink result fed back by the block chain network, and correspondingly storing the block identification information of the block where the transaction data is in the uplink result and the subject information.

That is to say, after the block chain network stores the uplink of the transaction data, the block identifier of the block where the transaction data is located may be fed back to the message production node, and the block identifier and the subject information of the message to be issued are stored correspondingly, so as to obtain the block identifier corresponding to the subject information from the block chain node, and further obtain the transaction data from the corresponding block.

S503, the subject information corresponding to the message to be issued and the identification information of the message generator node are sent to the block chain network, so that the subject information and the identification information are correspondingly stored by the block chain nodes in the block chain network.

Specifically, in order to facilitate acquisition of the transaction data corresponding to the subject information by other blockchain nodes in the blockchain network, the transaction data including the message to be issued may be acquired from a corresponding block in the blockchain network by using the block identifier in the blockchain node.

S504, the message acquirer receives the subject information and the corresponding identification information sent by the message producer node and stores the subject information and the corresponding identification information into a message service component deployed in the node.

Specifically, a message service component is deployed in each block chain node, an intelligent contract is deployed in the message service component, and corresponding theme information and identification information can be stored based on the intelligent contract. Meanwhile, the message generation node which issues the topic information is determined based on the topic information subscribed by the message acquirer, and further transaction data corresponding to the topic information is acquired.

S505, when the message acquirer node has a requirement for acquiring the transaction data, determining topic information subscribed by the message acquirer node, and determining identification information of the block chain node corresponding to the topic information based on the message service component.

That is to say, when it is determined that the message acquirer node needs to acquire the transaction data, the topic information subscribed by the message acquirer node may be acquired, and according to the topic information, the identification information of the block chain node corresponding to the topic information may be determined from the topic information stored in the message service component and the identification information of the corresponding block chain node, and then the corresponding block chain node is found based on the identification information.

S506, sending request information for obtaining the block identification of the subject information to the block link point corresponding to the identification information, so that the block link point obtains the block identification corresponding to the request information based on the request information. That is, according to the identification information, the corresponding blockchain node can be determined, and the blockchain node can obtain the blockchain node from the message service component, wherein the blockchain node corresponds to the subject information.

And S507, feeding back the block identifier to the message acquirer node, wherein the message acquirer node receives the block identifier, generates a transaction request for acquiring transaction data according to the block identifier, and sends the transaction request to the block chain network.

Specifically, the message acquirer node receives the block identifier fed back by the block chain node, and based on the block identifier, may determine the location of the transaction data corresponding to the subscribed topic information stored in the block chain, and in order to quickly acquire the transaction data including the message to be published, may generate a transaction request for acquiring the transaction data based on the block identifier, and send the transaction request to the block chain network, so as to acquire the transaction data from the block chain network.

And S508, after the message acquisition node receives the transaction data fed back by the blockchain network, checking the transaction data, processing the transaction data if the checking is successful, feeding back a processing result to the blockchain link point, and storing the processing result in the message service component.

It should be noted that the transaction data sent by the blockchain network to the message acquirer is signed, so that after the message acquirer node receives the transaction data fed back by the blockchain network, the transaction data needs to be signed by a signature check, if the signature check passes, the transaction data can be used, the processing result is fed back to the blockchain node that issues the subject information, and the processing result is stored in the message service component in correspondence with the subject information, that is, uplink storage, so that data tracking is facilitated.

As a preferred embodiment of the foregoing embodiments, fig. 6 is a schematic diagram of a block chain data processing method provided in an embodiment of the present invention, and as shown in fig. 6, a producer node is a message producer node, a consumer node is a message acquirer node, and both the producer node and the consumer node may be any node in a block chain network. The consensus node may be a block generation node in a block chain network.

The producer node may include a transaction request of the message to be published to the blockchain network side, and a message service component deployed in the producer node may obtain topic information topic1 in the message to be published and identification information of a corresponding producer node. The method comprises the steps of signing a transaction request containing a message to be issued based on a first block key, sending the signed transaction request to a block chain network, meanwhile, obtaining theme information of the message to be issued based on associated intelligent saving in a message service component, and sending the theme information and identification information of a producer node to a block chain node in the block chain network so as to store the theme information and corresponding identification information in the message service component in the block chain node.

The blockchain network may determine a blockgeneration node, which may be referred to as a consensus node. After receiving the transaction request, the consensus node can check the transaction request, and if the check passes, the consensus node can process the transaction request and store the uplink of the transaction data including the message to be issued. In order to determine the block identifier of the block where the transaction data is located, and further when the transaction data is tracked based on the block identifier, the common identification node may feed back the uplink result to the message producer node, where the uplink result includes the block identifier of the block where the transaction data is located, and the block identifier is stored in correspondence with the subject information in the message to be issued. If the signature verification fails, the transaction fails.

In this embodiment, the consumer node is a node that uses transactional data. The consumer node can subscribe the messages of all themes, after receiving the theme information and the corresponding identification information sent by the producer node, the consumer node checks the labels of the messages based on the message service components in the consumer node, and when the labels pass, the consumer node can store the labels in the message service components, namely, uplink storage. When a consumer node needs to acquire transaction data, whether identification information corresponding to subscribed topic information exists in a message service component or not can be acquired based on a subscribed message topic, if yes, a message producer node is determined according to the identification information, a block identifier corresponding to the topic information can be determined according to the message service component in the message producer node, the block identifier is fed back to the consumer node, the consumer node generates a transaction request corresponding to the block identifier and sends the transaction request to a block chain network, and then the transaction data are acquired from the block chain network and consumed.

After the consumer node obtains the transaction data and completes consumption, the consumption result can be fed back to the message producer node, and the consumption result and the identification information of the consumer node are uplink-stored in the message service component. Of course, the consumption result includes consumption success and consumption failure, and regardless of the consumption result, feedback and chain storage are required in order to trace and verify the transaction data.
