[0019] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification and not all embodiments. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this specification.

[0020] A blockchain system is a distributed network built from multiple nodes (blockchain nodes). Any two nodes within it communicate at the application layer via a peer-to-peer (P2P) network. See also... Figure 1 As shown, a blockchain system can, for example, contain nodes 1 to 5. Any two nodes from 1 to 5 can communicate at the application layer via a P2P network. The blockchain system utilizes a decentralized (or multi-centralized) distributed ledger constructed using a chain-like block structure, stored on each (or most) node in the distributed blockchain network. Therefore, the blockchain system needs to address the consistency and correctness of the ledger data across multiple decentralized (or multi-centralized) nodes. Accordingly, each node in the blockchain system runs a blockchain program. Under certain fault-tolerance requirements, a consensus mechanism ensures that all loyal nodes have the same transactions, thereby guaranteeing consistent execution results for the same transactions. Multiple transactions arranged in sequence are packaged into a block, and the world state is updated based on the execution results of these transactions. The current mainstream consensus mechanisms include, but are not limited to: Proof of Work (POW), Proof of Stake (POS), Practical Byzantine Fault Tolerance (PBFT) algorithm, Honey Badger Byzantine Fault Tolerance (HoneyBadgerBFT) algorithm, etc.

[0021] In blockchain systems, digital resources can be generated based on non-fungible tokens (NFTs). These digital resources typically possess characteristics such as non-fungibility, limited availability, and indivisibility. Different blockchains can use different NFT protocol standards to generate digital resources. Currently, mainstream protocol standards include ERC721, ERC1155, and ERC998. Among them, ERC721 is the most commonly used NFT protocol standard. Under the ERC721 standard, each generated digital resource has a unique identifier, and different digital resources are not interchangeable. It is difficult to measure the importance or value of different digital resources of the same category generated based on NFT protocol standards in specific application scenarios while ensuring fairness. For example, it is difficult to measure the importance or value of digital resources of the same category within the metaverse platform while ensuring public accessibility.

[0022] This specification provides a method for processing digital resources in a blockchain system, a blockchain node, and a processing system. After receiving a transaction requesting the setting of a digital resource in the blockchain system, the blockchain node sets a resource score for the digital resource based on several random numbers contained in the transaction. This allows for the measurement of the importance or value of different digital resources in specific application scenarios through their resource scores, while ensuring fairness.

[0023] Please continue reading Figure 1 As shown, the aforementioned processing system may include, for example, a blockchain system, device 1 held by the producer of the digital resources, and a trusted device. The trusted device may be a device provided by a trusted third party; or the trusted device may be implemented as a Trusted Execution Environment (TEE) of device 1. Furthermore, the producer can initiate transactions with the blockchain system through device 1 and / or request the trusted device to initiate transactions with the blockchain system through device 1 to issue digital resources in the blockchain system, the digital resources having a resource score determined based on several random numbers.

[0024] The processing system may also include, for example, device 2 held by the brand owner of the digital resources. The brand owner can initiate a transaction with the blockchain system through device 2 to authorize the publisher of their brand's copyright within the blockchain system. Furthermore, the publisher can initiate a transaction with the blockchain system through device 1 and / or request a trusted device through device 1 to initiate a transaction with the blockchain system to issue the authorized brand's digital resources within the blockchain system. These digital resources have a resource score determined based on several random numbers.

[0025] The processing system may also include, for example, a user-owned device 3 and a server of a target service platform (e.g., a metaverse platform), both of which can connect to the blockchain system. Furthermore, the user can initiate transactions with the blockchain system through device 3 to purchase / receive digital resources issued by the producer. Additionally, the user can utilize the purchased / received digital resources on the target service platform or other relevant platforms, for example, by using the purchased / received digital resources as their identifier on the target service platform and performing specific interactive operations with those digital resources on device 3.

[0026] The following will further combine the aforementioned points. Figure 1 The processing system shown in this specification provides a detailed description of the technical solutions provided in the embodiments.

[0027] Figure 2 This is one of the flowcharts for a method of processing digital resources in a blockchain system provided in the embodiments of this specification. The method describes the process by which producer a issues digital resource P in the blockchain system, such as... Figure 2 As shown, the method may include, but is not limited to, some or all of the following steps 200 to 206.

[0028] Step 200: Device 1 provides a resource setting request to the trusted device.

[0029] The resource setting request includes instruction information, and may also include the owner account, graphic data, and other information for issuing digital resource P that producer A wishes to issue. Digital resource P may correspond to brand B, which may be authorized to producer A by brand owner B in advance through a blockchain system. The relevant authorization information can be recorded on the blockchain system. Producer A can then issue digital resource P corresponding to brand B on the blockchain system. Digital resource P may be a digital resource belonging to brand B that producer A wishes to issue directly and is not attached to other products, or it may be a digital resource attached to a product of brand B that producer A wishes to issue. If digital resource P is a digital resource belonging to brand B that producer A wishes to issue directly and is not attached to other products, then the aforementioned other information for issuing digital resource P may include brand information of brand B, which may include, but is not limited to, brand name and brand logo. If digital resource P is a digital resource attached to a product X of brand B that producer A issues, then the aforementioned other information for issuing digital resource P may also include product information of product X, which may include, but is not limited to, product name and product code.

[0030] Digital resource P can be a digital resource in the form of non-fungible tokens, and the account to which digital resource P belongs can be, for example, an external account registered by producer a in the blockchain system. More specifically, digital resource P can be, for example, an image of a human figure or other shapes, such as a human figure image (hereinafter referred to as a virtual human), animal image, or jewelry image belonging to brand B, etc. The embodiments in this specification do not limit the form of digital resource P.

[0031] Step 202: The trusted device obtains several random numbers based on the indication information in the resource setting request.

[0032] The instruction information may include, for example, the number of random numbers the manufacturer expects the trusted device to acquire, and may also include the interval to which the random numbers acquired by the trusted device belong. Each random number acquired by the trusted device can satisfy a normal distribution within a specified interval, which may be an interval defined by the instruction information or an interval pre-set in the trusted device.

[0033] Step 204: The trusted device sends a transaction Tx1 containing several random numbers to the blockchain node in the blockchain system.

[0034] Transaction Tx1 is used to request the setting of digital resource P, that is, transaction Tx1 is used to request the generation of digital resource P in the blockchain system. In addition to the aforementioned random numbers, transaction Tx1 may also include other information located in the resource setting request, such as the owner account of digital resource P, the graphic data of digital resource P, and other information used to issue digital resource P.

[0035] Step 206: The blockchain node generates digital resource P based on transaction Tx1.

[0036] For example, transaction Tx1 can request to call smart contract C1. Blockchain nodes can execute transaction Tx1 to add resource data corresponding to digital resource P to the contract state of smart contract C1, thereby generating digital resource P in the blockchain system. In this process, the resource score of digital resource P is determined and set according to several random numbers in transaction Tx1.

[0037] The resource data corresponding to digital resource P may include at least one of the following: resource identifier, first resource score corresponding to each of several random numbers, resource score, resource level, owner account, brand information, product information, and graphic data; in addition, several target fields corresponding to several active attributes may be reserved. For the resource data corresponding to digital resource P, the first resource score corresponding to each of the several random numbers is prohibited from modification. The field values ​​of the aforementioned target fields can be set to NULL or 0 when generating digital resource P; however, the field values ​​of the target fields, resource score, and resource level are allowed to be changed based on certain specific rules after digital resource P is purchased / claimed by a user.

[0038] For example, a blockchain node can execute code segment 1 in smart contract C1 based on transaction Tx1 to generate a resource identifier for digital resource P based on brand information and / or product information in transaction Tx1. For example, a preset algorithm can be used to pre-process the brand information and / or product information to obtain the resource identifier for digital resource P.

[0039] For example, a blockchain node can execute code segment 2 in smart contract C1 based on transaction Tx1 to determine the first resource score corresponding to each of several random numbers. Code segment 2 can convert the random numbers located within a specified interval into first resource scores located within a certain preset interval. The larger the random number and the closer it is to the upper bound of the specified interval, the larger its corresponding first resource score; the smaller the random number and the closer it is to the lower bound of the specified interval, the larger its corresponding first resource score.

[0040] Taking the virtual human of digital resource P as an example, please refer to... Figure 3 In the resource setting request and transaction Tx1, for example, it may include multiple random attributes corresponding to the virtual human, specifically including six random attributes such as the virtual human's energy value, brain size, eye color, eye shape, aggressiveness, and resilience. The aforementioned instruction information can instruct the trusted device to obtain six random numbers corresponding to the aforementioned six random attributes. Furthermore, in the resource data corresponding to the digital resource P, the first resource score corresponding to each of the aforementioned six random numbers will be recorded under the six random attribute fields corresponding to the aforementioned six random attributes.

[0041] For example, a blockchain node can execute code segment 3 in smart contract C1 based on transaction Tx1 to determine the resource score of digital resource P based on the first resource score corresponding to each of several random numbers. For example, the sum of the first resource scores corresponding to each of several random numbers can be used to determine the resource score. In addition, it may also be possible to determine the resource level of digital resource P based on the resource score.

[0042] Continuing with the example of digital resource P being the aforementioned virtual human, assuming that the preset interval for the first resource score corresponding to each of the aforementioned 6 random numbers is the interval [1, 100], and the resource score is the sum of the first resource scores corresponding to each of the aforementioned 6 random numbers; furthermore, assuming that the resource data also includes two reserved target fields corresponding to the active attributes "active score" and "kind ship," the values ​​of these two target fields may change in the subsequent process based on certain rules, but they are still within the interval [0, 200]. Therefore, the resource score that may be re-determined in the subsequent process may be within the interval [6, 1000]. Please refer to... Figure 4 Blockchain nodes, for example, can be configured according to... Figure 4 The exemplary mapping relationship between resource scores and resource levels determines the resource level of digital resource P.

[0043] Figure 5 This is the second flowchart of a method for processing digital resources in a blockchain system provided in the embodiments of this specification. The method describes the process by which producer a issues digital resource P in the blockchain system, such as... Figure 5 As shown, the method may include, but is not limited to, some or all of the steps 500 to 510 below.

[0044] Step 500: Device 1 sends a transaction Tx2 to a blockchain node in the blockchain system to generate digital resource P.

[0045] Step 502: The blockchain node generates digital resource P based on transaction Tx2.

[0046] Transaction Tx2 can, for example, request the invocation of smart contract C1. Blockchain nodes can execute transaction Tx2 to add resource data corresponding to digital resource P to the contract state of smart contract C1, thereby generating digital resource P in the blockchain system. Both transaction Tx2 and the resource data of digital resource P can include one or more of the following information: the account to which digital resource P belongs, the brand information corresponding to digital resource P, and the product information. In addition, the resource data can also include a resource identifier determined based on the brand information and / or product information. For example, a blockchain node can execute code segment 1 in smart contract C1 based on transaction Tx2 to generate the resource identifier of digital resource P based on the brand information and / or product information in transaction Tx1. Specifically, this can be achieved by using a preset algorithm to process the brand information and / or product information to obtain the resource identifier of digital resource P. It should be noted that multiple fields can be reserved in the resource data of digital resource P. For example, several random attribute fields can be reserved to correspond to several random attributes, several active attribute fields can be reserved to correspond to several active attributes, and fields can be reserved to record information such as resource score and resource level. The field values ​​of the aforementioned reserved fields can be 0 or empty (NULL). The field value of the random attribute field will be prohibited from being modified after being modified once, while the field values ​​of the other reserved fields can be changed multiple times based on certain specific rules.

[0047] Digital resource P can be a digital resource in the form of non-fungible tokens, and the account to which digital resource P belongs can be, for example, an external account registered by producer a in the blockchain system. More specifically, digital resource P can be, for example, an image of a human figure or other shapes, such as a human figure image (hereinafter referred to as a virtual human), animal image, or jewelry image belonging to brand B, etc. The embodiments in this specification do not limit the form of digital resource P.

[0048] Step 504: Device 1 provides a resource setting request containing instruction information to the trusted device.

[0049] The instruction information may include, for example, the number of random numbers the manufacturer expects the trusted device to acquire, and may also include the interval to which the random numbers expected to be acquired by the trusted device belong. Each random number acquired by the trusted device can satisfy a normal distribution within the specified interval, which may be an interval defined by the instruction information or an interval pre-set in the trusted device. Furthermore, the instruction information may also include, for example, the resource identifier of the digital resource P and / or the ownership account of the digital resource P.

[0050] Step 506: The trusted device obtains several random numbers based on the instruction information in the resource setting request.

[0051] Step 508: The trusted device sends a transaction Tx1 containing several random numbers to the blockchain node.

[0052] Transaction Tx1 is used to request the setting of digital resource P, more specifically, transaction Tx1 is used to request the setting of resource fraction of digital resource P in the blockchain system. In addition to the aforementioned random numbers, transaction Tx1 may also include other information in the resource setting request, such as the resource identifier of digital resource P and / or the account to which digital resource P belongs.

[0053] Step 510: The blockchain node sets the resource score of digital resource P according to transaction Tx1.

[0054] For example, transaction Tx1 can request to invoke smart contract C1. Blockchain nodes can set the resource score of digital resource P in the contract state of smart contract C1 by executing transaction Tx1. More specifically, they can set the resource score of digital resource P in the resource data of digital resource P contained in the contract state of smart contract C1.

[0055] For example, a blockchain node can execute code segment 4 in smart contract C1 based on transaction Tx1 to query the resource data of digital resource P based on the resource identifier or owner account of digital resource P in transaction Tx1.

[0056] For example, a blockchain node can execute code segment 2 in smart contract C1 based on transaction Tx1 to determine the first resource score corresponding to each of several random numbers. Code segment 2 can convert the random numbers located within a specified interval into first resource scores located within a certain preset interval. The larger the random number and the closer it is to the upper bound of the specified interval, the larger its corresponding first resource score; the smaller the random number and the closer it is to the lower bound of the specified interval, the larger its corresponding first resource score.

[0057] For example, a blockchain node can execute code segment 2 in smart contract C1 based on transaction Tx1 to determine the first resource score corresponding to each of several random numbers, and execute code segment 3 in smart contract C1 based on transaction Tx1 to determine the resource score of digital resource P based on the first resource scores corresponding to each of the several random numbers. For example, the sum of the first resource scores corresponding to the several random numbers can be used to determine the resource score. In addition, it may be possible to determine the resource level of digital resource P based on the resource score. Then, the blockchain node submits the execution result of transaction Tx1, setting the first resource scores corresponding to each of the several random numbers under several reserved random attribute fields in the resource data of digital resource P, recording the resource score under the corresponding reserved fields in the resource data of digital resource P, and recording the resource level under the corresponding reserved fields in the resource data of digital resource P.

[0058] Figure 6 This is the third flowchart of a method for processing digital resources in a blockchain system provided in the embodiments of this specification. The method describes the process described above. Figure 2 or Figure 5 The various embodiments shown illustrate the process of a target user purchasing / receiving digital resource P through their device 3 after the issuance of digital resource P in the blockchain system. Figure 6 As shown, the method may include, but is not limited to, the following steps 600 and 602.

[0059] Step 600: Device 3 sends transaction Tx3 to the blockchain node in the blockchain system.

[0060] Transaction Tx3 may include a first account and a resource identifier for digital resource P. The first account may be an external account registered in the blockchain system by the target user holding device 3. Transaction Tx3 may request to call the aforementioned smart contract C1.

[0061] Step 602: The blockchain node sets the first account as the owner account of digital resource P according to transaction Tx3.

[0062] For example, a blockchain node can execute a smart contract C1 based on transaction Tx3 to update the ownership account of the digital resource recorded in the resource data of digital resource P to the first account included in transaction Tx3.

[0063] Target users through Figure 6 After purchasing / receiving digital resource P using the method shown, you can also increase the resource score of the digital resource based on your online interaction with the digital resource and your participation in offline activities of the brand B to which digital resource P belongs.

[0064] Figure 7 This is the fourth flowchart of a method for processing digital resources in a blockchain system provided in the embodiments of this specification. This method describes the process by which blockchain nodes increase the resource score of digital resource P based on the online interaction between the target user and the digital resource P. Figure 7 As shown, the method may include, but is not limited to, the following steps 700 and 702.

[0065] Step 700: Device 3 sends a transaction Tx4 to the blockchain node in the blockchain system to query digital resource P.

[0066] When a target user downloads relevant data of digital resources from the blockchain system through device 3 to apply digital resource P to other service platforms, such as downloading data such as the resource identifier, graphic data, resource score and resource level of a virtual person to use the virtual person as an avatar in other social platforms, the target user may need to send a request to the blockchain platform through their device 3 to query the transaction Tx4 of digital resource P. Transaction Tx4 is used, for example, to call the aforementioned smart contract C1.

[0067] Step 702: Update the second resource score of digital resource P according to transaction Tx4, and determine the resource score of digital resource P at least according to the second resource score and the first resource score corresponding to each of several random numbers.

[0068] A blockchain node can increase the second resource score of digital resource P based on the execution of transaction Tx4. The resource score of digital resource P is determined at least based on the updated second resource score and the first resource scores corresponding to the aforementioned random numbers. Furthermore, it can update the resource score and resource level of digital resource P, etc. For example, please refer to the preceding text. Figure 3 The field value under the target field corresponding to the active attribute kindship is the second resource score of digital resource P, and the field value under the target field corresponding to the active attribute active score is the third resource score of digital resource P. In essence, the blockchain node needs to redetermine and update the resource score of digital resource P based on the first resource score corresponding to each of the aforementioned random numbers, the updated second resource score corresponding to the active attribute kindship, and the third resource score corresponding to the active attribute active score. It can also determine whether to continue updating the resource level of digital resource P based on the updated resource score.

[0069] Figure 8 This is the fifth flowchart of a method for processing digital resources in a blockchain system provided in the embodiments of this specification. This method describes the process by which blockchain nodes increase the resource score of digital resource P based on the online interaction between a target user and digital resource P. Figure 8 As shown, the method may include, but is not limited to, the following steps 800 and 802.

[0070] Step 800: The server of the target service platform sends transaction Tx5 to the blockchain node in the blockchain system.

[0071] The graphical data in digital resource P may be used to support digital resource P as the identity identifier of the target user in the target service platform, and to display digital resource P on device 3. This graphical data may be determined, for example, based on the aforementioned random numbers, or based on the first resource score corresponding to each of the random numbers. The target user can perform corresponding interactive operations with digital resource P displayed on device 3, thereby enabling the server of the target server platform connected to device 3 to collect the behavioral data corresponding to the interactive operations between the target user and digital resource P. Then, the server of the target service platform sends a transaction Tx5 containing this behavioral data to the blockchain system. Transaction Tx5 is used, for example, to call the aforementioned smart contract C1.

[0072] Step 802: Update the second resource score of digital resource P according to transaction Tx5, and determine the resource score of digital resource P at least according to the second resource score and the first resource score corresponding to each of several random numbers.

[0073] A blockchain node can increase the second resource score of digital resource P based on the execution of transaction Tx5. The resource score of digital resource P is determined at least based on the updated second resource score and the first resource scores corresponding to the aforementioned random numbers. Furthermore, it can update the resource score and resource level of digital resource P, etc. For example, please refer to the preceding text. Figure 3 The field value under the target field corresponding to the active attribute kindship is the second resource score of digital resource P, and the field value under the target field corresponding to the active attribute active score is the third resource score of digital resource P. In essence, the blockchain node can redetermine and update the resource score of digital resource P based on the first resource score corresponding to each of the aforementioned random numbers, the updated second resource score corresponding to the active attribute kindship, and the third resource score corresponding to the active attribute active score. Furthermore, it can determine whether to continue updating the resource level of digital resource P based on the updated resource score.

[0074] Figure 9 This is the sixth flowchart of a method for processing digital resources in a blockchain system provided in the embodiments of this specification. This method describes the process of increasing the resource score of digital resource P based on user participation in offline activities of brand B, to which digital resource P belongs. Figure 9 As shown, the method may include, but is not limited to, the following steps 900 and 902.

[0075] Step 900: Device 3 sends transaction Tx6 to the blockchain node in the blockchain system.

[0076] Target users can participate in offline events hosted by brand B, the parent company of digital resource P. For example, they can use their device 3 to scan a QR code at the event venue or use other possible methods to obtain an event token and brand information for brand B. Then, device 3 sends a transaction Tx6 containing the event token and brand information for digital resource P to the blockchain system. Transaction Tx6, for example, is used to invoke the aforementioned smart contract C1.

[0077] Step 902: Update the third resource score of digital resource P according to transaction Tx6, and determine the resource score of digital resource P at least according to the third resource score and the first resource score corresponding to each of the several random numbers.

[0078] A blockchain node can increase the third resource score of digital resource P based on the execution of transaction Tx6. The resource score of digital resource P is determined at least based on the updated third resource score and the first resource scores corresponding to the aforementioned random numbers. Furthermore, it can update the resource score and resource level of digital resource P, etc. For example, please refer to the preceding text. Figure 3 The field value under the target field corresponding to the active attribute kindship is the second resource score of digital resource P, and the field value under the target field corresponding to the active attribute active score is the third resource score of digital resource P. In essence, the blockchain node can redetermine and update the resource score of digital resource P based on the first resource score corresponding to each of the aforementioned random numbers, the updated second resource score corresponding to the active attribute kindship, and the third resource score corresponding to the active attribute active score. Furthermore, it can determine whether to continue updating the resource level of digital resource P based on the updated resource score.

[0079] Through the technical solutions provided in the foregoing method embodiments of this specification, after a blockchain node receives a transaction requesting the setting of digital resources in the blockchain system, it sets the resource score of the digital resource in the blockchain system based on several random numbers contained in the transaction. This allows for the measurement of the importance or value of different digital resources in specific application scenarios through the resource score, while ensuring fairness. Furthermore, after a target user purchases / receives a digital resource, the resource score of the digital resource can be increased based on the target user's online interaction with the digital resource and the target user's participation in offline activities of the brand to which the digital resource belongs, thereby enhancing the importance or value of the digital resource.

[0080] Based on the same concept as the aforementioned method embodiments, this specification also provides a blockchain node in a blockchain system. For example... Figure 10As shown, the blockchain node includes: a transaction receiving unit 1000, configured to receive a first transaction, the first transaction being used to request the setting of a first digital resource in the blockchain system, the first transaction including a plurality of random numbers; and a transaction processing unit 1002, configured to set the resource score of the first digital resource in the blockchain system according to the first transaction, the resource score of the first digital resource being determined based on the plurality of random numbers.

[0081] Based on the same concept as the foregoing method embodiments, this specification also provides a digital resource processing system in a blockchain system. The processing system includes: a trusted device and a blockchain system; wherein the trusted device is used to obtain a plurality of random numbers and send a first transaction containing the plurality of random numbers to the blockchain system, causing blockchain nodes in the blockchain system to set a resource score for the first digital resource in the blockchain system according to the first transaction, the resource score of the first digital resource being determined based on the plurality of random numbers.

[0082] In one possible implementation, the processing system further includes a first device for providing a resource setting request to the trusted device, the resource setting request including indication information; wherein the trusted device is configured to obtain the plurality of random numbers according to the indication information.
