The present application relates to blockchain technology. The blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like. The Blockchain (Blockchain), which is essentially a decentralised database, is a string of data blocks that are generated by cryptographic means in association, each data block containing a batch of information of network transactions for verifying the validity of the information (anti-counterfeiting) and generating the next block.

Firstly, it should be noted that all data collected by the present application (such as all data related to on-link transaction data and off-link transaction data) are collected under the condition that the object (such as a user, an organization or an enterprise) to which the data belongs agrees and authorizes, and the collection, the use and the processing of the related data need to comply with the related laws and regulations and standards of the related country and region.

Here, a description will be given of a related art concept to which the present application relates:

intelligent contract: a digitally defined protocol is required to operate in a trusted environment, such as a blockchain platform. The intelligent contract (Smart contract) is a contract running in network space by means of a computer, is propagated, verified or executed in an informationized mode, is read and executed by the computer, and has the characteristic of self-service. Decentralizing the blockchain and tamper-proofing the data determine that the smart contract is more suitable for implementation on the blockchain. Therefore, the development of the blockchain technology enables the intelligent contract to have wider development prospect. An intelligent contract is in fact a piece of program made up of computer code, the association of which is: firstly, two or more parties participating in contract agree on a common consensus to form an intelligent contract; secondly, broadcasting and storing the intelligent contract to fulcrums of all global block chains through a block chain network; and thirdly, automatically executing contract contents after the intelligent contract with success is constructed and waiting conditions are met.

Centralizing the exchange: operated by a central authority, is responsible for maintaining the processing of all transactions of the digital resource and providing customer support.

Decentralizing exchanges: operated by a decentralizing organization, is a platform for trading digital resources on blockchains through intelligent contracts.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a network architecture according to an embodiment of the present application. As shown in fig. 1, the network architecture may include a blockchain network (belonging to a decentralized network), a centralized network, and transaction devices. The transaction processing device can be used for pulling transaction data of the digital resource from the blockchain network and the centralized network and calculating corresponding resource attribute information of the digital resource according to the pulled transaction data.

Alternatively, a plurality of blockchain nodes may be included in the blockchain network, the centralized network may be a distributed network, and the centralized network may include a plurality of distributed devices, where any blockchain node, distributed device, or transaction device may be formed by one or more computer devices, which may be servers or end devices, without limitation.

The servers described above may be independent physical servers, or may be server clusters or distributed systems formed by a plurality of physical servers, or may be cloud servers that provide cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDNs (distribution networks), and basic cloud computing services such as big data and artificial intelligence platforms. The terminal device described above may be: intelligent terminals such as intelligent mobile phones, tablet computers, notebook computers, desktop computers, intelligent televisions, vehicle-mounted terminals and the like.

Referring to fig. 2, fig. 2 is a schematic diagram of a scenario for generating resource attribute information according to an embodiment of the present application. As shown in fig. 2, the transaction device may invoke a first synchronization procedure to synchronize transaction data of digital resources from the blockchain network, which may be referred to as on-chain transaction data. The transaction device may also invoke a first synchronization program to synchronize transaction data of the digital resource from the centralized network, which may be referred to as under-chain transaction data.

The transaction processing device may call the first detection program to detect abnormality of the synchronized on-link transaction data and the off-link transaction data, and when abnormality is detected on the synchronized on-link transaction data and/or the off-link transaction data, may output first abnormality indication information, and may correct the synchronized transaction data (including the synchronized off-link transaction data and the off-link transaction data) according to the indication of the first abnormality indication information, so as to obtain corrected transaction data, and further, may generate accurate resource attribute information of the digital resource through the corrected transaction data. The above procedure may also be specifically described with reference to the following description of the corresponding embodiment of fig. 3.

Therefore, by adopting the method provided by the application, more perfect transaction data of the digital resource can be obtained through a plurality of channels of the blockchain network and the centralized network, in addition, in the process of synchronizing the transaction data of the digital resource through the blockchain network and the centralized network, the abnormal detection can be carried out on the transaction data of the synchronous digital resource, so that when the abnormal occurrence of the transaction data of the synchronous digital resource occurs, the alarm prompt can be timely carried out, and the transaction data of the synchronous digital resource can be corrected according to the abnormal condition of the transaction data of the synchronous digital resource, so that the accurate transaction data (namely corrected transaction data) of the digital resource can be obtained, and further, more accurate resource attribute information of the digital resource can be generated through the accurate transaction data.

Referring to fig. 3, fig. 3 is a flow chart of a transaction processing method according to an embodiment of the application. The execution body in the embodiment of the present application may be the above-mentioned transaction processing device, and as shown in fig. 3, the method may include:

step S101, calling transaction data of a first synchronous program synchronous digital resource; the synchronized transaction data includes on-chain transaction data synchronized to the digital resource from the blockchain network by invoking a first synchronization program, and off-chain transaction data synchronized to the digital resource from the centralized network by invoking the first synchronization program; the first synchronization program is embedded with a first detection program.

Alternatively, the transaction device is any device that may be used to obtain resource attribute information for a digital resource, and may not be a node device for a blockchain node in a blockchain network.

The first synchronization procedure may be used to provide a transaction synchronization service, e.g., the first synchronization procedure may be used to synchronize transaction data of a digital resource from a de-centralized network (e.g., a blockchain network) or/and a centralized network (e.g., other networks than a blockchain network).

The blockchain network may include a plurality of blockchain nodes, each of which may be formed by one or more computer devices, i.e., the node devices of the blockchain nodes may be one or more computer devices, and each of the blockchain nodes forms a decentralized blockchain network, so that the blockchain network may be referred to as a decentralized network.

And a centralized network may refer to a network that is centrally managed and operated, such as a network that is centrally managed by a government agency.

In the present application, the digital resource may be any kind of virtual resource (may also be referred to as an electronic resource), for example, the digital resource may be a digital stock, or an electronic security, or the like. Alternatively, there may be one or more digital resources in the present application, and the processing means for each digital resource is the same and independent, so the following description will take one digital resource as an example.

The transaction data of the digital resource may be data for transacting the digital resource, and the transaction data of the digital resource may be transaction data for transferring the digital resource through the universal resource, i.e. the transaction data of the digital resource may be understood as a transaction for the digital resource, such as a transaction for transferring the digital resource.

Wherein the universal resource and the digital resource may be different types of resources. As the name implies, the universal resource may refer to a resource that is commonly available on the market (i.e., a widely circulated resource), such as a common monetary resource.

It will be appreciated that the transactional data of the digital resource in the blockchain network may be performed by invoking a transactional execution contract in the blockchain network, i.e., an intelligent contract for executing the transactional data of the digital resource that would be uplink in the blockchain network.

While transaction data for a digital resource in a centralized network may include transaction data that is executed on the digital resource at several under-chain institutions, such as banks. Transaction data for the digital resource in the centralized network is not uplinked.

Thus, the transaction device may invoke the first synchronization program to synchronize the transaction data of the digital resource, which may include invoking the first synchronization program to synchronize the transaction data to the digital resource from the blockchain network (e.g., all of the currently generated transaction data synchronized from the blockchain network), and invoking the first synchronization program to synchronize the transaction data to the digital resource from the centralized network (e.g., all of the currently generated transaction data synchronized from the centralized network).

Where transaction data synchronized to a digital resource from a blockchain network may be referred to as on-chain transaction data, and transaction data synchronized to a digital resource from a centralized network may be referred to as off-chain transaction data.

In other words, the transaction device may invoke the first synchronization program to synchronize on-chain transaction data of the digital resource from the blockchain network, e.g., may invoke the first synchronization program to request the on-chain transaction data of the digital resource to be synchronized (e.g., pulled) from any blockchain node in the blockchain network; the transaction device may also invoke the first synchronization program to synchronize the under-chain transaction data of the digital resource from the centralized network, e.g., may invoke the first synchronization program to request the under-chain transaction data of the digital resource from a network device (which may be a background device, such as a server) to which the centralized network belongs, where the under-chain transaction data may include all transaction data currently existing by the digital resource in the centralized network.

Illustratively, the process of the transaction processing device invoking the first synchronization program to synchronize transaction data on a chain in a blockchain network may include:

the transaction processing device may invoke a configuration contract in the blockchain network based on the first synchronization program, e.g., the first blockchain program may request transaction data for the synchronous digital resource from any blockchain node in the blockchain network, which may invoke the configuration contract that was pre-configured to synchronize the transaction data for the digital resource through the configuration contract. Wherein the configuration contract is configured with a plurality of transaction execution contracts to be subjected to transaction synchronization, and the plurality of transaction execution contracts are intelligent contracts for executing transaction data of digital resources in the blockchain network.

Thus, the arbitrary block link point may acquire transaction data executed by the plurality of transaction execution contracts in the configuration contract through the invoked configuration contract, and may return the acquired transaction data executed by the plurality of transaction execution contracts to the transaction processing device (may include all transaction data that has been currently executed by the plurality of transaction execution contracts to the digital resource), so that the transaction processing device synchronizes from the blockchain network to the transaction data executed based on the plurality of transaction execution contracts, and the synchronized transaction data executed based on the plurality of transaction execution contracts may be used as the on-chain transaction data synchronized by the transaction processing device to the digital resource.

Wherein the configuration contracts may be pre-configured in a blockchain network, it is to be understood that there may be many smart contracts for executing transaction data of a digital resource, such as thousands of smart contracts for executing transaction data of a digital resource, and the plurality of transaction execution contracts configured in the configuration contracts may be portions of smart contracts selected from the thousands of smart contracts for executing transaction data of a digital resource.

Among the several intelligent contracts for executing the transaction data of the digital resource, the policy (may be referred to as a selection policy) of selecting the plurality of transaction execution contracts to be configured in the configuration contract may be determined according to the actual application scenario, which is not limited. For example, the first M intelligent contracts (e.g., top M) with the highest execution amount of transaction data of the digital resource can be selected, M is a positive integer, and M is equal to 100; or, the first N intelligent contracts (top N) with the highest transfer quantity of the history to the digital resource can be selected, wherein N is a positive integer, and if N can also be 100; alternatively still, K smart contracts (e.g., top K) having a greater importance degree may be selected according to the importance degree of each smart contract for executing the transaction data of the digital resource (the importance degree of the transaction data that may be executed may be used to represent the importance degree of the transaction data that is executed, the more important smart contract may be used to execute the more important transaction data of the digital resource), where K is a positive integer, e.g., K is 50, and the importance degree of each smart contract may be configured in advance for each smart contract.

The specific number of the transaction execution contracts configured in the configuration contract can be determined according to the actual application scene, and the specific number is not limited. A transaction execution contract is understood to be an off-centered exchange, which is used to execute transaction data of digital resources based on an off-centered manner.

Referring to fig. 4, fig. 4 is a schematic diagram of a scenario for acquiring transaction data on a chain according to an embodiment of the present application. As shown in fig. 4, the configuration contracts can be configured with a transaction execution contract 1, a transaction execution contract 2, a transaction execution contract 3, a transaction execution contract 4 and a transaction execution contract 5, so that all the transaction data which is currently called and executed by the transaction execution contract 1, all the transaction data which is currently called and executed by the transaction execution contract 2, all the transaction data which is currently called and executed by the transaction execution contract 3, all the transaction data which is currently called and executed by the transaction execution contract 4 and all the transaction data which is currently called and executed by the transaction execution contract 5 can be acquired through the configuration contracts, and the acquired transaction data form synchronous on-chain transaction data.

Illustratively, the process of the transaction processing device invoking the first synchronization program to synchronize transaction data on a chain in a blockchain network may include:

the above-described centralized network for synchronizing the downlink transaction data of the digital resources may also be preconfigured. In other words, the transaction device may invoke a first synchronization program to synchronize the under-chain transaction data of the digital resource to the pre-configured centralized network. The centralized network can be understood as a centralized exchange, and the number of the centralized networks can be determined according to the actual application scenario.

The first synchronization program is embedded with a detection program, and the detection program embedded in the first synchronization program may be referred to as a first detection program, where the first detection program may be embedded in the first synchronization program by means of instrumentation, and the first detection program may be a program configured in the first synchronization program and used for detecting a service (such as a transaction synchronization service) provided by the first synchronization program, that is, the first detection program may detect whether the service provided by the first synchronization program is abnormal during the process that the first synchronization program provides the service, which may be described in detail below.

Step S102, a first detection program is called to detect abnormality of the synchronous transaction data, and when abnormality of the synchronous transaction data is detected, first abnormality indication information is output; the first abnormality indication information is used for indicating abnormal transaction data in the synchronized transaction data.

Alternatively, the transaction processing device may call the first detection program to perform anomaly detection on the synchronized transaction data, that is, detect whether the first synchronization program has an anomaly in the transaction data synchronized by the digital resource. The transaction processing device may output first abnormality indication information when detecting that the synchronized transaction data has an abnormality, so as to timely alert and prompt that the synchronized transaction data has an abnormality through the first abnormality indication information, where the first abnormality indication information may be used to indicate abnormal transaction data in the synchronized transaction data, and the abnormal transaction data that has an abnormality and is indicated by the first abnormality indication information may be referred to as abnormal transaction data.

Wherein the transaction processing device invoking the first detection program to perform anomaly detection on the synchronized transaction data may include: the transaction processing device may call the first detection program to perform anomaly detection on the on-chain transaction data and the off-chain transaction data, i.e. the transaction processing device may call the first detection program to perform anomaly detection on the synchronized on-chain transaction data, and may call the first detection program to perform anomaly detection on the synchronized off-chain transaction data.

Thus, alternatively, the above-described abnormal transaction data may be any of the following: the above-mentioned chain transaction data, or the above-mentioned chain transaction data and the below-chain transaction data. In other words, the abnormal transaction data may be on-chain transaction data, indicating that the first abnormality indication information is used to indicate that the on-chain transaction data has an abnormality; alternatively, the abnormal transaction data may be the under-chain transaction data, which indicates that the first abnormal indication information is used to indicate that the under-chain transaction data has an abnormality; still alternatively, the abnormal transaction data may be on-chain transaction data and off-chain transaction data, which indicate that the first abnormal indication information is used to indicate that the on-chain transaction data and the off-chain transaction data have an abnormality.

The first exception indication information may also be used to indicate a specific exception condition detected for the abnormal transaction data, for example, the exception condition may be that the transaction data is duplicated or that the transaction data is missing, etc.

Step S103, correcting the abnormal transaction data indicated by the first abnormal indication information in the synchronized transaction data to obtain the transaction data after correcting the synchronized transaction data.

Optionally, the transaction processing device may perform corresponding correction processing on the abnormal transaction data based on the abnormal situation specifically indicated by the first abnormal indication information on the abnormal transaction data, so as to obtain transaction data after correction on the synchronized transaction data.

In one possible implementation, if the abnormal transaction data includes the on-link transaction data and the off-link transaction data synchronously, the correction processing on the abnormal transaction data may refer to performing respective correction processing on the on-link transaction data and the off-link transaction data.

For example, if the first exception indication information is used to indicate that the above-mentioned exception transaction data has repeated transaction data (i.e. the pulled exception transaction processing has repeated transaction data), the transaction processing device may perform deduplication processing on the exception transaction data in the synchronized transaction data, so as to obtain the transaction data after deduplication. The deduplication process may be a correction process, and the deduplicated transaction data may be corrected transaction data.

If the abnormal transaction data synchronization includes the above-mentioned on-chain transaction data and off-chain transaction data, the transaction processing device may perform deduplication processing on the on-chain transaction data and the off-chain transaction data, respectively, where the deduplicated transaction data includes the deduplicated on-chain transaction data and the deduplicated off-chain transaction data.

For another example, if the first exception indication information is used to indicate that the abnormal transaction data has missing transaction data (such as a pull failure or a pull incompleteness of a certain transaction), the transaction processing device may perform a complementary process on the transaction data missing from the abnormal transaction data in the synchronized transaction data, so as to obtain the transaction data after the complementary process. The supplementing process may belong to a correction process, and the post-supplementing transaction data may be corrected transaction data.

Similarly, if the abnormal transaction data synchronization includes the above-mentioned on-chain transaction data and off-chain transaction data, the transaction processing device may perform complementary processing on the on-chain transaction data and the off-chain transaction data, respectively, where the complementary transaction data includes complementary on-chain transaction data and complementary off-chain transaction data.

If the transaction data on the chain has missing transaction data, the transaction data on the chain is pulled to a blockchain node in the blockchain network by the transaction processing device, which indicates that the blockchain node may have abnormal operation, so that the transaction processing device can re-pull the transaction data missing from the transaction data on the chain to another blockchain node in the blockchain network to obtain the transaction data on the chain after supplementation.

Alternatively, the centralized network may be a distributed network (including a plurality of distributed devices), where the transaction data of the digital resource in the centralized network may be stored in the plurality of distributed devices, so if the under-link transaction data has missing transaction data, the under-link transaction data is pulled by the transaction processing device to any one of the distributed devices, which indicates that the distributed device may have abnormal operation, and therefore, the transaction processing device may re-pull the transaction data missing by the under-link transaction data to another distributed device in the centralized network, so as to obtain the supplementary under-link transaction data.

If the abnormal transaction data only includes the on-chain transaction data, but does not include the off-chain transaction data, the corrected transaction data may include the originally normal off-chain transaction data and the corrected on-chain transaction data. Similarly, if the abnormal transaction data only includes the under-chain transaction data, but does not include the on-chain transaction data, the corrected transaction data may include the originally normal on-chain transaction data and the corrected under-chain transaction data.

Step S104, the corrected transaction data is comprehensively processed to generate the resource attribute information of the digital resource.

Optionally, the transaction processing device may aggregate (may be a summary process) the transaction data belonging to the blockchain network and the transaction data belonging to the centralized network in the corrected transaction data to obtain a first transaction data set, where the first transaction data set may include the transaction data belonging to the blockchain network and the transaction data belonging to the centralized network in the corrected transaction data.

If the abnormal transaction data only includes the on-chain transaction data, but not the off-chain transaction data, the transaction data belonging to the blockchain network in the corrected transaction data can be corrected on-chain transaction data, and the transaction data belonging to the centralized network in the corrected transaction data can be originally normal off-chain transaction data.

If the abnormal transaction data only comprises the under-chain transaction data and does not comprise the on-chain transaction data, the transaction data belonging to the blockchain network in the corrected transaction data can be the originally normal on-chain transaction data, and the transaction data belonging to the centralized network in the corrected transaction data can be the corrected under-chain transaction data.

If the abnormal transaction data comprises the under-chain transaction data and the on-chain transaction data at the same time, the transaction data belonging to the blockchain network in the corrected transaction data can be corrected on-chain transaction data, and the transaction data belonging to the centralized network in the corrected transaction data can be corrected under-chain transaction data.

Further, the transaction processing device may perform comprehensive analysis processing on the transaction data in the first transaction data set to generate resource attribute information of the digital resource, where the resource attribute information may include market information related to the digital resource.

Alternatively, the synchronized transaction data may be obtained at the target time, and the transaction data of the digital resource may be transaction data for transferring the digital resource through a universal resource (such as a universal currency of a country) (e.g., a user may transfer a corresponding amount of the digital resource to another user after obtaining a corresponding amount of the universal resource provided by another user), so the resource attribute information of the digital resource may include at least one of the following: a target unit conversion amount of the digital resource between the target time and the universal resource; at the target time, a target variation range of a unit conversion amount between the digital resource and the universal resource (for reflecting an increase or decrease range of the digital resource at the target time); the total amount of resource transfer (such as transaction amount) of the digital resource at the target moment; the total amount of transaction data (e.g., transaction amount) of the digital resource at the target time.

Further, the resource attribute information of the digital resource may also include a time-sharing diagram, a K-ray diagram, etc. of the digital resource. The time-sharing graph may represent the price (such as the unit conversion amount between the digital resource and the universal resource) of the digital resource at each moment (such as at one moment every one minute) in a graph manner, and the K-graph may represent the highest price, the lowest price, the driving price and the receiving price of the digital resource every day in a graph manner.

It can be understood that no matter which attribute information is included in the resource attribute information of the digital resource, the attribute information can be generated correspondingly after being comprehensively processed based on the transaction data of the digital resource according to the actual application scene. In the following processes, the processes of performing corresponding processing on a plurality of transaction data of the digital resource together to generate resource attribute information corresponding to the digital resource can be understood as the process of comprehensively processing the transaction data of the digital resource.

The target unit conversion amount can be understood as the unit price of the digital resource at the target time, for example, the target unit conversion amount can be used to represent how much universal resource is needed to be used for transferring the digital resource.

The target change width may be a change width of a target unit conversion amount based on a history unit conversion amount, the history unit conversion amount may be a comprehensive unit conversion amount of a digital resource and a universal resource on a natural day before the natural day on which the target time is located, the comprehensive unit conversion amount may be a unit conversion amount commonly accepted between the digital resource and the universal resource on the previous day, for example, the comprehensive unit conversion amount may be a closing price of the digital resource on the previous day, in other words, the target change width of the unit conversion amount between the digital resource and the universal resource at the target time may be a unit conversion amount of a closing of the digital resource on the previous natural day on which the digital resource belongs than the natural day on which the digital resource belongs at the target time.

For example, the process of calculating the target unit conversion amount by the first transaction data set may include: the transaction device may calculate a resource conversion amount of the digital resource and the universal resource in respective transaction data of a first transaction data set, one transaction data of the first transaction data set being used for calculating a resource conversion amount between the digital resource and the universal resource.

The conversion amount of the digital resource and the universal resource in one transaction data can be used for reflecting the unit price of the digital resource in the transaction data.

For example, any one of the transaction data in the first transaction data set may be target transaction data, and the process of calculating the resource conversion amounts of the digital resource and the universal resource in the target transaction data may include: the transaction device may extract a resource transfer amount of the digital resource from the target transaction data and a resource consumption amount of the universal resource for transferring the digital resource.

Thus, the transaction device may calculate a ratio between the resource consumption amount of the universal resource and the resource transfer amount of the digital resource in the target transaction data, and use the ratio as the resource conversion amount of the digital resource and the universal resource in the target transaction data, in other words, the resource conversion amount may be equal to a value obtained by dividing the resource consumption amount of the universal resource by the resource transfer amount of the digital resource.

Further, the transaction processing device may perform an average calculation (i.e., calculate an average value) of the resource conversion amounts calculated by the respective transaction data in the first transaction data set (i.e., the resource conversion amounts of the digital resource and the general resource in the respective transaction data in the first transaction data set), so as to generate the target unit conversion amount, in other words, the target unit conversion amount may be an average value of the resource conversion amounts of the digital resource and the general resource in the respective transaction data at the target time and before the target time.

The process of generating the transaction data total amount of the digital resource at the target moment through the first transaction data set may include: the transaction device may count the total number of transaction data in the first transaction data set, and the counted total number may be the total amount of transaction data.

Further, the process of generating a total amount of resource transfer of the digital resource at the target time by the first transaction data set may include: the transaction processing device may extract the resource transfer amounts of the digital resources from each transaction data of the first transaction data set, and further, the transaction processing device may add (i.e. sum) the resource transfer amounts of the digital resources extracted from each transaction data set, so as to obtain the total resource transfer amount of the digital resources at the target time.

Further, when the transaction processing device invokes the first detection program and does not detect that the synchronized transaction data has an exception, it indicates that the on-chain transaction data and the off-chain transaction data are both normal (i.e., accurate), so that the transaction processing device may directly aggregate (e.g., summarize) the on-chain transaction data and the off-chain transaction data to obtain a second transaction data set of the digital resource, where the second transaction data set may be formed by the on-chain transaction data and the off-chain transaction data.

Further, the transaction device may perform integrated analysis of the transaction data in the second transaction data set to generate resource attribute information for the digital resource. Here, the process of analyzing the transaction data in the second transaction data set to generate the resource attribute information of the digital resource is the same as the process of analyzing the transaction data in the first transaction data set to generate the resource attribute information of the digital resource.

More, after the transaction processing device generates the resource attribute information of the digital resource through the first transaction data set or the second transaction data set, the transaction processing device may further call the first detection program to perform anomaly detection on the generated resource attribute information, that is, detect whether the generated resource attribute information is anomalous, for example, detect whether comprehensive analysis processing of the first transaction data set or the second transaction data set is incorrect, or detect whether the generated resource attribute information is complete, and so on. Specifically, which abnormal conditions need to be detected, the first detection program can be configured correspondingly according to the actual application scene, and the method is not limited.

When the transaction device does not detect that the generated resource attribute information has an abnormality, it indicates that the generated resource attribute information is normal (i.e., accurate), and therefore, the transaction device may store the generated resource attribute information to the attribute information base of the digital resource.

When the transaction processing device detects that the generated resource attribute information is abnormal (such as that the comprehensive processing process is wrong or the generated resource attribute information is incomplete), the transaction processing device can output second abnormality indication information (such as that the second abnormality indication information can be sent to a terminal device of an associated technician for output), wherein the second abnormality indication information is information for indicating that the generated resource attribute information is abnormal, and the generated resource attribute information can be timely prompted and alarmed through the output second abnormality indication information.

The transaction processing device may further perform correction processing on the generated resource attribute information under the instruction of the second abnormality instruction information, so as to obtain corrected resource attribute information, and may store the corrected resource attribute information in the attribute information library.

As the name suggests, the attribute information base may be a database for storing resource attribute information of digital resources.

The correction processing for the generated resource attribute information may refer to performing corresponding correction for the generated resource attribute information according to the specific abnormal situation indicated by the second abnormal indication information for the generated resource attribute information.

For example, if the second abnormality indication information is used to indicate that the generated resource attribute information is incomplete, the non-generated resource attribute information that is missing in the generated resource attribute information may be generated (e.g., regenerated) in a complementary manner, so as to obtain corrected resource attribute information.

For another example, if the second abnormality indication information is used to indicate that the generated resource attribute information is incomplete, which indicates that the integrated processing of the first transaction data set or the second transaction data set is inaccurate, the corresponding integrated processing (i.e. retry) may be performed again on the first transaction data set or the second transaction data set until the accurate resource attribute information is generated for the digital resource. If the number of retries reaches the specified number threshold, and accurate resource attribute information is not generated for the digital resource, an error can be reported to prompt a corresponding technician to perform corresponding investigation on the first synchronization program.

Further, after storing the resource attribute information of the digital resource in the attribute information base, the second synchronization program may further render and display the resource attribute information of the digital resource in the attribute information base, and the process may include:

The transaction processing device may call a second synchronization program for synchronizing resource attribute information of the digital resource from the attribute information base, the second synchronization program may be a program for synchronizing resource attribute information of the digital resource from the attribute information base and for rendering and displaying the synchronized resource attribute information, and the second synchronization program may be used for providing a synchronization service (may be simply referred to as an attribute synchronization service) for the resource attribute information of the digital resource.

The second synchronization program may be embedded with a second detection program, and the second detection program may be embedded in the second synchronization program by means of instrumentation.

After the second synchronization program is called to synchronize the resource attribute information of the digital resource from the attribute information base, the transaction processing device may also call the second detection program to perform anomaly detection on the synchronized resource attribute information, for example, to detect whether the synchronized resource attribute information is complete and accurate, or to detect whether the operation of the synchronized resource attribute information is successfully performed, and so on.

When no abnormality is detected in the synchronized resource attribute information, the transaction processing device may render and display the synchronized resource attribute information to a resource client (which may be a client for performing front-end display and processing on related information of the digital resource), for example, the transaction processing device may send the synchronized resource attribute information to the resource client, so that the resource client may render and display the received resource attribute information to a client interface.

When the abnormality of the synchronized resource attribute information is detected, the transaction processing device may output third abnormality indication information (for example, may be sent to a terminal device of an associated technician for output), where the third abnormality indication information may be information for indicating that the abnormality of the synchronized resource attribute information exists, and the abnormality of the synchronized resource attribute information may be timely indicated and alerted by the output third abnormality indication information.

And the transaction processing device can correct the synchronous resource attribute information under the instruction of the third abnormal instruction information to obtain corrected resource attribute information, and further, the corrected resource attribute information can be rendered and displayed on the resource client, for example, the transaction processing device can send the corrected resource attribute information to the resource client, so that the resource client can render the received resource attribute information to a client interface for displaying.

For example, the transaction processing device may perform corresponding correction processing on the synchronized resource attribute information according to the specific abnormal situation indicated by the third abnormal indication information on the synchronized resource attribute information, so as to obtain corrected resource attribute information.

For example, if the third abnormality indication information indicates that the synchronized resource attribute information is abnormal due to too large access amount of the attribute information base or an access error to the attribute information base, the transaction processing device may call the second synchronization program to retry the synchronization of the resource attribute information of the digital resource from the attribute information base, so as to obtain corrected resource attribute information.

More, the application can set the update frequency of the resource attribute information of the digital resource, such as one update per minute (which can be understood as an update period), and then the latest resource attribute information of the digital resource can be generated per minute according to the above flow and stored in the attribute information base. Therefore, the application can also perform abnormality detection on the updated resource attribute information in the attribute information base (or call the first detection program to detect), if the period of updating the resource attribute information in the attribute information base is detected to be not the set updating period, the application indicates that the updating of the resource attribute information in the attribute information base is abnormal, and can also output corresponding abnormality indication information, wherein the abnormality indication information is used for indicating that the updated resource attribute information in the attribute information base is abnormal.

For example, if the resource attribute information is updated (e.g., stored) multiple times in a minute, it indicates that the resource attribute information in the attribute information library is updated too frequently, and an abnormality occurs, and the corresponding abnormality indication information may be output. For another example, if more than one minute (such as 2 minutes or 3 minutes, etc.), the resource attribute information in the attribute information base is not updated continuously (for example, no latest resource attribute information is stored in the attribute information base continuously), it indicates that the update of the resource attribute information in the attribute information base fails, an abnormality occurs, and corresponding abnormality indication information can be output.

The application can call the transaction data of the first synchronous program synchronous digital resource; the synchronized transaction data includes on-chain transaction data synchronized to the digital resource from the blockchain network by invoking a first synchronization program, and off-chain transaction data synchronized to the digital resource from the centralized network by invoking the first synchronization program; a first detection program is embedded in the first synchronization program; invoking a first detection program to detect abnormality of the synchronized transaction data, and outputting first abnormality indication information when abnormality of the synchronized transaction data is detected; the first abnormality indication information is used for indicating abnormal transaction data in the synchronized transaction data; correcting abnormal transaction data indicated by first abnormal indication information in the synchronized transaction data to obtain corrected transaction data of the synchronized transaction data; and comprehensively processing the corrected transaction data to generate resource attribute information of the digital resource. Therefore, the method provided by the application can synchronize the transaction data of the digital resource from the blockchain network, and can synchronize the transaction data of the digital resource from the centralized network, so that the transaction data can be synchronized to more perfect transaction data of the digital resource from different channels (such as the blockchain network and the centralized network), and in the process of synchronizing the transaction data of the digital resource from different channels, the embedded detection program in the synchronization program can be called to perform abnormal detection on the synchronized transaction data, so that the accuracy of the synchronized transaction data is ensured, and therefore, the accuracy of the resource attribute information of the digital resource generated by the synchronized transaction data (such as the corrected transaction data of the synchronized transaction data) can be doubly improved.

Referring to fig. 5, fig. 5 is a schematic structural diagram of a system architecture according to an embodiment of the present application. As shown in FIG. 5, an attribute synchronization service may be provided by the first synchronization program described above, which may be used to synchronize the in-chain transaction data of digital resources from a centralized exchange (e.g., a centralized network), and may be used to synchronize the in-chain transaction data of digital resources from an off-centralized exchange according to a blockchain configuration contract (e.g., a configuration contract described above).

The information synchronization service may be used to synchronize information about the digital resource from an external platform (e.g., other information platforms for the digital resource) and may also place the information into an attribute information repository (DB) of the digital resource, where the update frequency of the information may be consistent with the frequency of updating the resource attribute information of the digital resource by the transaction data, such as may be updated once per minute.

The abnormality detection task may be used to perform abnormality detection on the update frequency of the resource attribute information of the digital resource in the attribute information library, and if it is detected that the update frequency of the resource attribute information of the digital resource is abnormal (if the update frequency is inconsistent with the preset update frequency), abnormality reporting (i.e. abnormality alarm) may be performed, for example, corresponding abnormality indication information may be reported to a risk alarm platform, where the risk alarm platform may operate in a terminal device of a related technician, so that the related technician may timely view an abnormality condition for the attribute information library.

In addition, the first abnormality indication information obtained by the attribute synchronization service performing abnormality detection on the synchronized transaction data may be output in the risk alarm platform. In practice, the various abnormality indication information described above (including the first abnormality indication information to the third abnormality indication information) may be output in the risk alert platform.

Subsequently, the resource client may request to access a corresponding service, such as accessing an attribute calling service (which may access an associated access interface configured by the attribute calling service) or accessing an information calling service (which may access an associated access interface configured by the information calling service), before the resource client requests to access the corresponding service, the user needs to log in an account in the resource client, and after the login state of the user and the authority verification of the access of the corresponding service are successful, the user may successfully access the corresponding service in the resource client. Wherein the attribute invocation service may be provided by the second synchronization service described above.

The resource attribute information of the digital resource can be synchronized in the attribute information base through the accessed attribute calling service, and further, the resource attribute information synchronized with the digital resource can be rendered and displayed in the resource client. The information calling service accessed can synchronize the information of the digital resource in the attribute information base, and further, the information synchronized with the digital resource can be rendered and displayed in the resource client.

Referring to fig. 6 and fig. 7, fig. 6 is a schematic diagram of an interface for rendering and displaying resource attribute information according to an embodiment of the present application, and fig. 7 is a schematic diagram of an interface for rendering and displaying resource attribute information according to another embodiment of the present application. As shown in fig. 6, the resource attribute information may be a time-sharing graph of the digital resource, and in a client interface of the resource client, the time-sharing graph of the digital resource may be rendered and displayed. As further shown in fig. 7, the resource attribute information may be a K-ray diagram of the digital resource, and in a client interface of the resource client, the K-ray diagram of the digital resource may be rendered and displayed.

Referring to fig. 8, fig. 8 is a flowchart illustrating a process of rendering display resource attribute information according to an embodiment of the present application. As shown in fig. 8, the process may include:

1. the business party can configure a digital resource list in the configuration contract, wherein the digital resource list can contain one or more digital resources needing to generate and display resource attribute information according to the flow, and the transaction execution contract list contains the configured various transaction execution contracts needing to perform transaction data synchronization. The business party may be a party to the resource client, where the business party may request from the blockchain network, through its own background device, that the digital resource list and the transaction execution contract list be configured in a configuration contract. 2. The attribute synchronization service may invoke a configuration contract to request a decentralised trade contract (i.e., a transaction execution contract configured in the configuration contract) to synchronize transaction data executed by the decentralised trade contract. 3. The decentralized transaction contract may return the executed transaction data to the attribute synchronization service.

4. In addition, the attribute synchronization service may further perform anomaly detection on transaction data (such as on-chain transaction data) synchronized from the centralized exchange and transaction data (such as off-chain transaction data) synchronized from the centralized exchange, respectively, and if an anomaly is detected, perform an alarm, such as outputting the first anomaly indication information. 5. The attribute synchronization service may give the first abnormality indication information to the risk alert platform, so that the risk alert platform may output the first abnormality indication information. 6. The attribute synchronization service may further perform correction processing on the synchronized transaction data based on the indication of the first abnormality indication information, so as to obtain corrected transaction data, and may generate resource attribute information of the digital resource through the corrected transaction data (which belongs to the synchronized correct transaction data), and may add the resource attribute information to the attribute information base.

7. Subsequently, the front end (e.g., resource client) may obtain the resource attribute information of the digital resource through the access gateway service request. 8. The access gateway service may initiate verification of the user's login state (e.g., whether it is in a normal login state) before acquiring the resource attribute information of the digital resource according to the request of the front end. 9. The access gateway service may request the service party to verify the current login status of the user. 10. After verifying the current login state of the user, the service party can return a verification result of the login state of the user to the access gateway service.

11. The access gateway service may query the attribute call service for resource attribute information of the digital resource when detecting that the authentication result is a result of passing the authentication. 12. The attribute calling service can query the attribute information of the digital resource for the latest resource attribute information of the digital resource in the attribute information base of the digital resource. 13. The attribute invocation service may return the resource attribute information of the queried digital resource to the access gateway service. 14. The access gateway service may return the resource attribute information of the latest digital resource queried to the resource client. 15. The resource client can render and display the resource attribute information of the received digital resource in the client interface.

Alternatively, the transaction data executed by invoking the transaction execution contract in the blockchain network may be initiated by a resource client (which may be a resource client of any user, and is not limited to the resource client that requests to acquire and display the resource attribute information) to the blockchain network.

By the method, corresponding anomaly detection can be carried out at each stage (such as a transaction data synchronization stage, a resource attribute information generation stage, a resource attribute information synchronization stage and the like) before the resource attribute information of the digital resource is rendered and displayed, so that the accuracy of the resource attribute information of the finally rendered and displayed digital resource is ensured.
