The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
FIG. 1 is an application environment diagram of a method of block chain network transaction information tracking in one embodiment. Referring to fig. 1, a block chain network 100 in an embodiment of the present application includes a plurality of nodes 101 and a data center 102. The plurality of nodes 101 may communicate with each other via a network, and the plurality of nodes 101 may each communicate with the data center 102 via the network.
Wherein, a plurality of nodes 101 may be in peer-to-peer status, and each node 101 may be a server or a workstation, and the whole network 100 may not depend on a dedicated centralized server or a dedicated workstation. Each node 101 can act as a requester of a network service and respond to requests from other nodes. Thus, the method of blockchain network transaction information tracking in the practice of the present application is applicable to each of the plurality of nodes 101 in the blockchain network 100.
The node 101 may be a desktop terminal or a mobile terminal, and the mobile terminal may specifically be at least one of a mobile phone, a tablet computer, a notebook computer, and the like. In addition, node 101 may be a server, which may be implemented as a stand-alone server or as a server cluster including a plurality of servers. The application is not limited to what device node 101 is specifically.
The data center 102 may be a desktop terminal or a mobile terminal, and the mobile terminal may specifically be at least one of a mobile phone, a tablet computer, a notebook computer, and the like. The data center 102 may also be a server, which may be implemented as a stand-alone server or as a cluster of servers. The particular type of equipment in the data center 102 is not limiting.
Further, the plurality of nodes 101 in the blockchain network 100 may be aware of each other of identities, and the node identities may be node names, node identifications, and other information that may characterize the uniqueness of the nodes in the blockchain network 100, so as to implement communication and consensus verification between the plurality of nodes 101.
In one embodiment, the blockchain network 100 may be a public network such as the internet, where each node 101 needs to sign information sent by the node to ensure the security of information transmission; in addition, in other embodiments, the blockchain network 100 may also operate in a proprietary network, in which case the signing process of the information it sends by the node 101 may be simplified. Typically, each node 101 in the blockchain network 100 has a respective private key and public key, the public key disclosing the private key used to sign the information sent by itself. The application does not limit the specific mode of node signature.
Further, in the blockchain network 100, each node 101 may include a plurality of component modules (which may be understood as functional modules that implement specific functions) for respectively performing different processing on transaction information.
Specifically, in one embodiment, as shown in fig. 2, the component modules of each node 101 specifically include: an interface module, a network routing module, a consensus module, a virtual machine module, an account book module and the like. The interface module is used for receiving and transmitting information with a client accessing the blockchain network. The network routing module is used to implement connection communication between nodes 101, between nodes 101 and data center 102. The virtual machine module can be understood as a set of program rules, for example, in a bitcoin system, the sending and receiving of bitcoin can only be performed, the sending and receiving process is completed through the set of program rules, and the program rules in the virtual machine module can also be written by a user, so that the functions of a blockchain network, such as the functions of intelligent contracts of an Ethernet, can be expanded; a variety of business functions may be implemented in the blockchain through the virtual machine module, such as billing through the blockchain, recording orders, recording crowd funding accounts, recording logistics information, recording supply chain information, and the like. The account book module is used for generating blocks according to the transaction data and linking the blocks one by one. The consensus module comprises a consensus algorithm, wherein the consensus algorithm can be understood as a rule, and each node in the network confirms account book data of each node according to the rule; in blockchain network 100, each node 101 maintains a ledger and must keep its ledger consistent with the ledgers of other nodes, so that the blockchain network uses the ledger data of each node to agree through a consensus algorithm.
Based on the blockchain network shown in fig. 2, from the time when a user initiates a new transaction message through a client to the time when corresponding blocks are generated in the ledgers of the respective nodes 101, this process requires the joint participation of a plurality of nodes and a plurality of component modules in the respective nodes, and may include:
(1) The node 1 receives transaction information submitted by the client through the interface module. (2) After receiving the transaction information, the node 1 enters the consensus module and is processed by the consensus module. (3) The node 1 executes corresponding virtual machine transaction logic aiming at the transaction information. (4) The node 1 puts the current transaction information into the latest transaction list of the block, and performs account book verification for the current transaction information. (5) After the node 1 locally completes the operation, an execution result of the transaction information is obtained, and the transaction execution result is returned to the client. (6) The node 1 broadcasts block information including the current transaction information to other nodes. (7) The node 2 receives the block information broadcast by the node 1 and processes the block information by the consensus module. (8) The node 2 executes corresponding virtual machine transaction logic for the transaction information. (9) node 2 performs ledger checking for the current transaction information. (10) node 2 broadcasts the ledger check result to other nodes. (11) Each node receives account book verification results broadcast by other nodes. (12) And carrying out consensus voting of the transaction according to the account book checking results broadcasted by other nodes, and judging whether consensus is achieved. (13) If consensus is reached, the node 1 returns a consensus result corresponding to the transaction information to the client. (14) After consensus is reached, each node also saves the block containing the current transaction information to the account book, i.e. adds the block containing the current transaction information to the blockchain. The client can be an APP or a browser. The form of the client is not limited. Through the process, the blockchain accounting of the transaction is completed.
Further, in the embodiment of the present application, each node 101 is further configured with a log module in advance, so as to generate a log record corresponding to at least one transaction processing transaction. The execution of a transaction message in the blockchain network 100 may be recorded by logging, such as which node or nodes currently are executing the associated transaction or which component modules are executing the associated transaction. The data center 102 may actively or passively obtain log record information for all nodes 101 in the blockchain network 100, thereby tracking the execution of transaction information in the blockchain network 100 based on the log records obtained by the data center 102.
Based on the above description of the application environment, a method for tracking blockchain network transaction information is provided. In one embodiment, as shown in fig. 3, the blockchain network transaction information tracking method is applied to any node 101 in fig. 1 for illustration. The method for tracking the blockchain network transaction information can comprise the following steps:
s301, aiming at transaction information to be tracked, detecting transaction processing transactions locally executed by the nodes.
The transaction information to be tracked can be any business information which is recorded through a blockchain network. The transaction performed locally by the node may be any transaction performed by the node for the transaction information to be tracked, including, but not limited to, receiving transaction information by the interface, consensus checking, virtual machine execution logic, ledger checking, signing, broadcasting execution results, receiving consensus checking results by other nodes, consensus voting, returning execution results to the client, saving execution result information to the ledger, and the like.
In the embodiment of the application, the node can detect the transaction processing transaction which is locally executed by the node aiming at the transaction information to be tracked in real time. Of course, the node may also detect according to a set time interval, and may specifically be set according to an actual situation.
S302, inquiring a target transaction set according to the detected transaction processing transaction; the set of target transactions includes target transaction processing transactions.
The target transaction set may include a data set of one or more target transaction transactions, where a target transaction may be understood as a corresponding log record to be generated once the corresponding transaction is executed in the node.
S303, if the detected transaction belongs to the target transaction in the target transaction set, generating a log record corresponding to the detected transaction; the log record comprises at least one of identity information of the node and component module information corresponding to the transaction processing transaction.
The identity information of the node is information capable of uniquely identifying the node in the blockchain network, such as node name, node identification information, address information, or the like. The component module information may be the name, identity, or other information that uniquely identifies the component module in a node.
In the embodiment of the application, the formats of the log records corresponding to different target transaction processing transactions can be the same or different. In addition, the generation mode of the log record can be determined according to the log module configured by each node, and in some embodiments, the generation mode of the log record unified by the whole network can be preconfigured, which is not limited in the application.
S304, the log record corresponding to the transaction processing transaction detected at this time is stored locally in the node.
In the embodiment of the application, the log record corresponding to the transaction processing transaction detected at the time can be stored in the appointed position in the node, for example, the log record corresponding to the transaction processing transaction is stored in the cache of the node, so that the log query request of the data center can be responded quickly.
S305, sending log records related to transaction records stored locally by the nodes to a data center so as to track transaction information to be tracked through the data center.
In some embodiments, the node may actively send the log record corresponding to the locally generated transaction to the data center, e.g., may send the log record corresponding to the generated transaction to the data center in real time; the node can also send the log record corresponding to the transaction processing transaction stored locally to the data center according to the set time period. In other embodiments, the node may also passively send the locally stored log record corresponding to the transaction to the data center, for example, when receiving a log query request from the data center, send the log record corresponding to the transaction to the data center.
In addition, the log query request of the data center can also carry log screening conditions, and after the node receives the log query request, the node acquires the log record corresponding to the log screening conditions from the locally stored log record and sends the log record to the data center. Therefore, the method can selectively collect the log information of the nodes in the blockchain network and track and position the transaction information in a targeted manner.
According to the embodiment of the application, the node can detect the transaction processing transaction executed for the transaction information in real time in the process of processing the transaction information, and the corresponding log record is generated and stored for the specific transaction processing transaction, namely, in the embodiment of the application, the log record corresponding to the transaction information is synchronously generated with the execution of the transaction processing transaction, so that the data center can acquire the log record corresponding to the transaction information of the node in time, and the effect of tracking the transaction information in real time is realized.
In the method for tracking the transaction information of the blockchain network, in each node in the blockchain network, the transaction processing transaction locally executed by the node can be detected aiming at the transaction information to be tracked; then inquiring a target transaction set according to the detected transaction processing transaction; if the currently detected transaction belongs to the target transaction in the target transaction set, generating a corresponding log record for the currently detected transaction; the log record can comprise at least one of node information and component module information; and storing the generated log record locally at the node; and sending the log record corresponding to the transaction processing transaction stored locally by the node to the data center, so that the transaction information to be tracked can be tracked through the data center. The data center can locate the current processing node of the transaction information to be tracked by collecting the log records of one or more nodes in the network and can also locate the specific component module in the processing node, so that the transaction information entering the blockchain network can be tracked and located conveniently.
In one embodiment, the step S301 specifically includes: aiming at transaction information to be tracked, detecting transaction processing transactions locally executed by a node through a preset log switch interface; and the log switch interface is used for locally generating log records corresponding to all target transaction processing transactions in the target transaction set at the node in an enabling state.
Accordingly, the method for tracking the blockchain network transaction information can further comprise the following steps: a log switch interface is configured for each node in the blockchain network. The log switch interface can be an interface with corresponding system rights, and by configuring the log switch interface, detection of target transaction processing transaction in the node can be realized and log records can be generated. Specifically, this step may include: configuring a log switch interface of the node; configuring a target transaction processing transaction corresponding to the log switch interface; and generating a target transaction set corresponding to the log switch interface according to the target transaction processing transaction corresponding to the log switch interface.
The configuration method of the log switch interface of each node in the blockchain network can be determined according to the operating system of the node, so that the configuration methods of the log switch interfaces of different nodes can be different. When the nodes in the blockchain network are the same devices, the configuration methods of the log switch interfaces of the different nodes can be the same. Whether the configuration methods are the same or not, the function of detecting the target transaction processing transaction of the node and generating the log record can be realized through the log switch interfaces of all the nodes.
In one embodiment, the state of the log switch interface of each node may be selected, e.g., the log switch interface may be in an enabled state and the log switch interface may be in a disabled state. Or, the switch interfaces of some nodes may be in an enabled state, and the log switch interfaces of other nodes may also be in a disabled state, which may be specifically set according to the situation.
In the embodiment of the application, the target transaction processing transactions in the target transaction set corresponding to the log switch interface may be one or more, and the specific setting of the target transaction processing transactions may be set according to the actual situation, and generally, the key processing process of one transaction information in the blockchain network may be set as the target transaction processing transaction corresponding to the log switch interface.
In one embodiment, the target transaction processing transactions contained in the target transaction set may include at least one of: receiving transaction information initiated by a client through an interface module, performing consensus verification on the transaction information through a consensus module, executing corresponding virtual machine transaction logic on the transaction information, and executing account book verification on the transaction information; the node broadcasts an execution result corresponding to the transaction information to other nodes in the network; the node receives execution results corresponding to transaction information broadcast by other nodes; the node consensus module performs consensus voting according to the execution results broadcasted by other results; the node returns an execution result corresponding to the transaction information to the client through the interface module; and storing an execution result corresponding to the transaction information to the blockchain through the account book module.
In addition to the transaction transactions listed above, the target transaction set corresponding to the log switch interface may also include other transaction transactions, which is not limited in this disclosure.
In one embodiment, in the step S303, a specific process of generating the log record corresponding to the transaction processing transaction may include: acquiring a transaction identifier corresponding to a transaction processing transaction; acquiring a node identifier and a component module identifier of a transaction processing transaction occurrence node; acquiring occurrence time and description information of transaction processing matters; and generating a log record corresponding to the transaction processing transaction according to the transaction identifier, the node identifier, the component module identifier, the occurrence time and the description information. The description information of the transaction processing transaction may include information such as a processing type, a processing state, a processing time consumption, and/or a processing result, which is not limited.
In one embodiment, in the step S305, the specific process of sending, by the node, the log record stored locally by the node to the data center may include:
receiving a log query request sent by a data center; the log inquiry request carries log screening conditions; obtaining a log record corresponding to the log screening condition from the log record locally stored by the node, and taking the log record as a target log record; and sending the target log record to a data center.
Therefore, the data center can collect log records of one or more nodes in the network, further locate the current processing node of the transaction information to be tracked, and locate the specific component module in the processing node, so that the transaction information entering the blockchain network can be tracked and located conveniently. And on the basis of tracking and positioning transaction information of the blockchain network, the nodes in the blockchain network are also convenient to manage, for example, when the time for common check of one node is found to be obviously longer than that of other nodes, the performance of the node is required to be optimized, and the node optimization or maintenance is required to be performed in time. Similarly, the component modules of the nodes in the blockchain network are convenient to manage, and when the transaction processing transaction state of one component module is found to be failed for a plurality of times, the component module is indicated to be updated or replaced.
The following describes the method for tracking the blockchain network transaction information according to the present invention with reference to fig. 4, which includes the following steps:

S402, detecting transaction processing transactions executed by each node locally aiming at transaction information to be tracked through a log switch interface.
S403, inquiring a target transaction set according to the currently detected transaction processing transaction; judging whether the currently detected transaction belongs to the transaction in the target transaction set; if yes, executing the next step.
If the currently detected transaction does not belong to the target transaction in the target transaction set, which indicates that the user does not care about the transaction, the log record of the transaction may not be generated, so as to reduce the burden of the node.
S404, a corresponding log record is generated for the currently detected transaction, and relevant information of the currently detected transaction is recorded through the log record, for example, node and component module information, occurrence time information, processing state information, processing details and the like which can occur through log record processing are recorded.
S405, carrying out local caching on the generated log record.
S406, the user sets log screening conditions through the data center, and the data center receives the log screening conditions set by the user.
The log screening condition may be one or more of transaction identifier, node identifier, component identifier, occurrence time and processing type, and may be specifically set according to actual situations. In general, the log filtering condition that can be set by the data center should be included in the log record generated by the node, for example, if the log filtering condition includes a transaction identifier, the log record generated by the node should also include a transaction identifier of the transaction information.
S407, when the data center receives the operation instruction for inquiring the log, generating a corresponding log inquiry request according to the set log screening condition, and respectively sending the log inquiry request to nodes in the blockchain network.
S408, after receiving the log query request of the data center, the node screens out the corresponding log record from the locally cached log records.
