Description

Technical Field

[0001] One or more embodiments of this specification relate to the field of blockchain technology, and more particularly, to a method and apparatus for processing digital resources in a blockchain. Background Art

[0002] Blockchain is a novel application model for computer technologies, including distributed data storage, peer-to-peer transmission, consensus mechanisms, and encryption algorithms. In a blockchain, data blocks are linked sequentially in chronological order to form a chain-like data structure, and cryptography is used to ensure that these blocks cannot be tampered with or forged. Due to its decentralized, tamper-proof, and autonomous nature, blockchain is gaining increasing attention and application.

[0003] In blockchains, digital resources can be generated based on non-fungible tokens (NFT) technology. These digital resources typically have characteristics such as non-fungibility, limited availability, and indivisibility. Different blockchains can use different NFT protocol standards to generate digital resources. For example, current mainstream protocol standards include ERC721 and ERC1155. 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 with each other. Under the ERC1155 standard, resource identifiers do not correspond to a single resource, but to a category of resources. Resources of different categories are not interchangeable, while different resources within a category are the same and interchangeable, and the number of resource categories is limited.

[0004] At present, due to the uniqueness and limited nature of digital resources, their prices are prone to malicious speculation. A technical solution is needed to curb the malicious speculation of digital resources. Summary of the Invention

[0070] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0071] In order to more clearly illustrate the technical solutions of the embodiments of this specification, the following briefly introduces the drawings required for use in the description of the embodiments. Obviously, the drawings described below are only some embodiments recorded in this specification. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative labor.

[0077] To help those skilled in the art better understand the technical solutions in this specification, the following will provide a clear and complete description of the technical solutions in the embodiments of this specification, in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of this specification, not all of them. All other embodiments derived by those skilled in the art based on the embodiments in this specification without creative effort shall fall within the scope of protection of this specification.

[0078] like Figure 1 , which is a diagram of the blockchain architecture used in the embodiments of this specification.

[0079] Figure 1 In the example, the blockchain contains 8 nodes, namely nodes 1 to 8. Each node can be implemented as any device, server or device cluster with computing and processing capabilities. Figure 1 Although the blockchain is shown as including eight nodes, the embodiments of this specification are not limited thereto and may include other numbers of nodes. Specifically, the nodes included in the blockchain can meet Byzantine Fault Tolerance (BFT) requirements. This Byzantine Fault Tolerance requirement can be understood as allowing Byzantine nodes to exist within the blockchain without externally displaying Byzantine behavior. Generally, some Byzantine Fault Tolerance algorithms require the number of nodes to be greater than 3f+1, where f is the number of Byzantine nodes. For example, the Practical Byzantine Fault Tolerance (PBFT) algorithm requires that the number of nodes be greater than 3f+1, where f is the number of Byzantine nodes.

[0080] Figure 1In the diagram, the lines connecting the nodes schematically represent P2P (Peer to Peer) connections. These nodes store the full ledger, that is, the status of all blocks and all accounts. Each node in the blockchain generates the same state by executing the same transactions, and each node in the blockchain stores the same state database. Furthermore, each node is responsible for receiving transactions from clients and initiating a consensus proposal to other nodes. This consensus proposal includes, for example, multiple transactions in the block to be formed (e.g., block B1) and the order in which each transaction should be submitted. After the nodes in the blockchain successfully reach consensus on the consensus proposal, each node executes the multiple transactions according to the submission order specified in the consensus proposal, thereby generating block B1.

[0081] I understand. Figure 1 The blockchain shown is only exemplary and the embodiments of this specification are not limited to application in Figure 1 The blockchain shown can also be applied to a blockchain system including sharding, for example.

[0082] In blockchains, non-fungible tokens (NFTs) can be used to generate digital assets (e.g., game props, digital artwork, and digital memorabilia). These assets are typically non-fungible, limited in quantity, and indivisible. In related technologies, digital assets are typically issued independently. Due to their uniqueness and limited availability, their prices are susceptible to malicious speculation. Currently, the only solution to this problem is enhanced manual oversight, which is complex, ineffective, and reduces the efficiency of digital asset transactions.

[0083] The embodiment of this specification provides a Figure 1 The solution for processing digital resources in the blockchain shown here is to bind a preset amount of circulating resources to digital resources. When the digital resources are transferred, a certain amount of circulating resources is deducted. Since the amount of bound circulating resources no longer increases, it can effectively reduce the possibility of digital resources being maliciously speculated to a certain extent, thereby improving the transaction efficiency of digital resources.

[0084] The solution provided in this specification will be described in detail below with reference to specific embodiments.

[0085] like Figure 2A As shown, Figure 2A This is a flowchart illustrating a method for processing digital resources in a blockchain, according to an exemplary embodiment. This method can be applied to a blockchain node. The blockchain node can be implemented as any device, platform, server, or device cluster with computing and processing capabilities. The method includes the following steps:

[0086] First, in step 201, in response to receiving a transaction for transferring a digital resource, the remaining amount of circulating resources corresponding to the current digital resource is determined. Then, in step 202, if the remaining amount meets a preset condition, the owner of the digital resource is changed. Finally, in step 203, the first amount of circulating resources is deducted from the remaining amount of circulating resources.

[0087] Specifically, the digital resources involved in this embodiment may be non-replaceable, limited, and indivisible digital resources. For example, the digital resources may be NFT digital resources generated based on non-fungible token technology. It is understood that any other non-replaceable, limited, and indivisible digital resources known in the art or that may appear in the future may be applied to the digital resources of this embodiment. This embodiment does not limit the specific form and type of the above-mentioned digital resources.

[0088] In this embodiment, when creating the digital resource, a corresponding circulation resource of the digital resource can be created at the same time, and the digital resource and the corresponding circulation resource of the digital resource can be bound and stored in the blockchain in an associated manner. The circulation resource can be a digital resource with characteristics such as fungibility and unlimited quantity, and can be split. For example, the circulation resource can be a (Fungible Tokens, homogenized token) FT digital resource. It can be understood that any other digital resources with characteristics such as fungibility, unlimited quantity, and can be split that are known in the art or may appear in the future can be applied to the circulation resources of this embodiment. This embodiment does not limit the specific form and type of the above-mentioned circulation resources.

[0089] Specifically, the data structure of the digital resource can be stored in the blockchain. Figure 2B This is a schematic diagram of a data structure of a digital resource provided in an embodiment of this specification, such as Figure 2B As shown, the data structure may include, for example, but not limited to, identification information of the digital resource, circulation resource information corresponding to the digital resource, circulation information of the digital resource, metadata corresponding to the digital resource, and the like.

[0090] The metadata corresponding to the digital resource may include, but is not limited to, a content introduction (e.g., information about the author, a brief introduction to the creation process, and a brief introduction to the content), image information (e.g., images of the digital resource), 3D information, video information, and audio information. The circulation resource information corresponding to the digital resource may include, but is not limited to, an identifier of the circulation resource and a circulating balance.

[0091] In this embodiment, the initial amount of the circulating resources corresponding to the digital resource can be a fixed value. For example, regardless of whether the digital resource is a rare digital artwork with a circulation volume of 1 or a payment code skin with a circulation volume of 1,000, the initial amount of the corresponding circulating resources can be a fixed value of 10,000.

[0092] Optionally, the initial amount of the circulating resource can also be determined based on the circulation volume of the digital resource, specifically, it can be positively correlated with the circulation volume of the digital resource. For example, if the digital resource is a rare digital artwork with a circulation volume of 1, the initial amount of its circulating resource can be 10. If the digital resource is a payment code skin with a circulation volume of 1000, the initial amount of its circulating resource (i.e., the initial amount of the circulating resource of each of the 1000 payment code skins) can be 10,000.

[0093] After the digital resource is created, users can buy, sell, and transfer it through a client connected to the blockchain node. Specifically, during the digital resource transfer process, the remaining amount of the circulating resource corresponding to the digital resource can be determined. Then, the owner of the digital resource can be changed, and a first amount of circulating resources can be deducted from the remaining amount of circulating resources. If the remaining amount is greater than or equal to the first amount, the transaction is successful; if the remaining amount is less than the first amount, the transaction fails. It should be noted that the deduction of circulating resources is generally achieved by pre-creating an account on the blockchain that can only transfer in, not out. The deduction is then achieved by transferring the circulating resources to this account.

[0094] Among them, the first amount to be deducted can be a fixed value. For example, no matter the digital resource is a rare digital artwork with a circulation of 1, or a payment code skin with a circulation of 1,000, the corresponding first amount to be deducted can be a fixed value of 1.

[0095] Alternatively, the first amount to be deducted may be inversely correlated with the circulation of the digital resource. For example, if the digital resource is a rare digital artwork with a circulation of 1, the corresponding first amount to be deducted may be 2. If the digital resource is a payment code skin with a circulation of 1,000, the corresponding first amount to be deducted (i.e., the first amount to be deducted for each of the 1,000 payment code skins) may be 1.

[0096] Since rare resources are more likely to be maliciously speculated, this embodiment further considers the relationship between the initial amount of circulating resources and the issuance volume of digital resources, as well as the relationship between the amount deducted during transfer and the issuance volume of digital resources, thereby more effectively avoiding the malicious speculation of rare resources.

[0097] In summary, in one implementation, regardless of whether the digital resource is a rare digital artwork with a circulation of 1 or a payment code skin with a circulation of 1,000, the initial amount of the corresponding circulating resource can be a fixed value of 10,000. However, the amount to be deducted is inversely correlated with the circulation of the corresponding digital resource. For example, for a rare digital artwork with a circulation of 1, the amount to be deducted can be 1,000, while for a payment code skin with a circulation of 1,000, the amount to be deducted can be 1.

[0098] In another implementation, if the digital resource is a rare digital artwork with a circulation quantity of 1, the initial amount of the corresponding circulating resource may be 10. If the digital resource is a payment code skin with a circulation quantity of 1,000, the initial amount of the corresponding circulating resource may be 10,000. However, the amount to be deducted can be a fixed value of 1.

[0099] In another implementation, if the digital resource is a rare digital artwork with a circulation quantity of 1, the initial amount of the corresponding circulating resource may be 100, and the amount to be deducted may be 10. If the digital resource is a payment code skin with a circulation quantity of 1,000, the initial amount of the corresponding circulating resource may be 10,000, and the amount to be deducted may be 1.

[0100] It can be seen that the above-mentioned implementation methods can all avoid the malicious speculation of scarce resources to varying degrees.

[0101] Alternatively, the first amount can be determined as follows: First, a base amount to be deducted can be determined, where the base amount to be deducted is negatively correlated with the issuance volume of the digital resource. Next, a current transaction popularity value for the digital resource is determined, and the first amount is determined based on the base amount to be deducted and the transaction popularity value. The transaction popularity value represents the popularity of the digital resource in circulation, and the popularity of the digital resource in circulation can be quantified as the transaction popularity value.

[0102] In this embodiment, the transaction heat value can be positively correlated with at least one of the following: the number of times the digital resource is transferred within a preset time period (for example, the number of times the digital resource is bought and sold within a preset time period before the current time); the resource amount corresponding to the digital resource (for example, the current price of the digital resource, etc.); the increase in the resource amount corresponding to the digital resource (for example, the increase in the current price of the digital resource compared to the previous price, etc.); the number of times the same account is involved in the transfer of the digital resource in history (for example, the number of times the same account is involved in the purchase and sale of the digital resource). The transaction heat value can be negatively correlated with at least one of the following: the time interval between the last transfer of the digital resource and the current time; the decrease in the resource amount corresponding to the digital resource (for example, the decrease in the current price of the digital resource compared to the previous price, etc.). It can be understood that the transaction heat value can also be determined by other quantitative values that can represent the heat of the digital resource in circulation. This embodiment does not limit the specific value of the transaction heat value.

[0103] Specifically, the offset can be determined based on the transaction heat value. For example, the offset corresponding to the transaction heat value can be found from a preset correspondence table (the correspondence table records the correspondence between the preset transaction heat value range and the preset offset), or the product of the transaction heat value and a preset weight is determined as the offset. Then, the sum of the base amount to be deducted and the offset is determined as the first amount. It is understood that the first amount can also be determined based on the base amount to be deducted and the offset in other ways, and this embodiment is not limited to this aspect.

[0104] Since this embodiment takes into account that the popularity of digital resources in circulation can reflect malicious speculation to a certain extent, the transaction heat value reflecting the heat is used to adjust the amount to be deducted from the circulating resources, thereby further avoiding the situation where digital resources are maliciously speculated.

[0105] The following combination Figure 3Taking digital resource A as an example, the process of creating and transferring digital resource A is described below: First, in step 301, user A can initiate a transaction Tx1 on the blockchain using user device a to create digital resource A with a circulation quantity of m. Transaction Tx1 carries information about the circulation quantity m. In step 302, after receiving transaction Tx1, the blockchain node can obtain the circulation quantity m from transaction Tx1 and determine the initial amount n of the circulating resource B corresponding to digital resource A based on the circulation quantity m, such that the initial amount n is positively correlated with the circulation quantity m. Then, each digital resource A is created according to the circulation quantity m (e.g., including digital resource A1, digital resource A2, ..., digital resource Am). For each digital resource A, a corresponding circulating resource B with an initial amount n is created (e.g., circulating resource B1 corresponding to digital resource A1 has an initial amount n, circulating resource B2 corresponding to digital resource A2 has an initial amount n, ..., circulating resource Bm corresponding to digital resource Am has an initial amount n). Each digital resource A is associated with its corresponding circulating resource B with an initial amount n and stored in the blockchain. Furthermore, the initial owner of each digital resource A and its corresponding circulating resource B is User A. Finally, in step 303, the blockchain node sends a message to User Device A confirming the creation of digital resource A. User A can view the message on User Device A. Furthermore, any user with viewing permission can view the amount of digital resource A and its corresponding circulating resource B through the blockchain node.

[0106] Next, in step 304, user B can initiate a transaction Tx2 on the blockchain using user device b to transfer digital resource A1. In step 305, after receiving transaction Tx2, the blockchain node can first determine the remaining amount of circulating resource B corresponding to the current digital resource A1, for example, the remaining amount is n. It then determines the amount a to be deducted, which can be negatively correlated with the circulation volume m of digital resource A. In step 306, after the transfer amount is paid, the blockchain node changes the owner of digital resource A1 from user A to user B and deducts the amount a of circulating resource B from the amount n of circulating resource B. At this point, the remaining amount of circulating resource B is na. Digital resource A1 is associated with the circulating resource B with the remaining amount na and stored in the blockchain. It should be noted that if the remaining amount n is less than the amount a to be deducted, transaction Tx2 fails, and user A remains the owner of digital resource A1.

[0107] The above-mentioned embodiments of this specification provide a method for processing digital resources in a blockchain. By binding a preset amount of circulating resources to digital resources, a certain amount of circulating resources is deducted when the digital resources are transferred. Since the amount of bound circulating resources no longer increases, this method can effectively reduce the possibility of malicious speculation of digital resources to a certain extent, thereby improving the transaction efficiency of digital resources.

[0108] It should be noted that although the operations of the methods of the embodiments of this specification are described in a specific order in the above embodiments, this does not require or imply that the operations must be performed in this specific order, or that all of the operations shown must be performed to achieve the desired results. On the contrary, the steps depicted in the flowcharts can be performed in a different order. Additionally or alternatively, certain steps can be omitted, multiple steps can be combined into one step, and / or a step can be broken down into multiple steps.

[0109] Corresponding to the aforementioned method embodiment for processing digital resources in a blockchain, this specification also provides an embodiment of an apparatus for processing digital resources in a blockchain.

[0110] like Figure 4 As shown, Figure 4 This is a block diagram of an apparatus for processing digital resources in a blockchain, according to an exemplary embodiment of this specification.

[0133] In the 1990s, technological improvements could be clearly distinguished as either hardware improvements (for example, improvements to circuit structures like diodes, transistors, and switches) or software improvements (improvements to process flows). However, with the advancement of technology, many process flow improvements today can now be considered direct improvements to hardware circuit structures. Designers almost always create the corresponding hardware circuit structure by programming the improved process flow into the hardware circuit. Therefore, it cannot be said that a process flow improvement cannot be implemented using hardware modules. For example, a programmable logic device (PLD), such as a field programmable gate array (FPGA), is an integrated circuit whose logical function is determined by user programming. Designers can "integrate" a digital system on a PLD through their own programming, without having to hire a chip manufacturer to design and manufacture a dedicated integrated circuit chip. Moreover, nowadays, instead of manually fabricating integrated circuit chips, this programming is mostly done using "logic compiler" software. This is similar to the software compiler used when developing programs. Before compilation, the original code must also be written in a specific programming language, called a hardware description language (HDL). There is not just one HDL, but many, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. The most commonly used ones are VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art will also understand that by simply programming the method flow in one of these hardware description languages and then programming it into an integrated circuit, a hardware circuit that implements the logic method flow can be easily obtained.

[0134] The controller can be implemented in any suitable manner. For example, the controller can take the form of a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro)processor, logic gates, switches, application-specific integrated circuits (ASICs), programmable logic controllers, and embedded microcontrollers. Examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320. The memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art will also know that in addition to implementing the controller in a purely computer-readable program code format, the controller can be implemented in the form of logic gates, switches, application-specific integrated circuits, programmable logic controllers, and embedded microcontrollers by logically programming the method steps. Therefore, such a controller can be considered a hardware component, and the devices included therein for implementing various functions can also be considered as structures within the hardware component. Or even, the devices for implementing various functions can be considered as both software modules that implement the method and structures within the hardware component.

[0135] The systems, devices, modules or units described in the above embodiments may be implemented by computer chips or entities, or by products with certain functions. A typical implementation device is a server system. Of course, this application does not exclude that with the future development of computer technology, the computer that implements the functions of the above embodiments may be, for example, a personal computer, a laptop computer, an in-vehicle human-computer interaction device, a cellular phone, a camera phone, a smart phone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.

[0136] Although one or more embodiments of this specification provide method operation steps as described in the embodiments or flow charts, more or fewer operation steps may be included based on conventional or non-creative means.

When the device or terminal product in practice is executed, it can be executed in sequence or in parallel according to the method shown in the embodiments or the drawings (for example, a parallel processor or a multi-threaded processing environment, or even a distributed data processing environment). The term "comprise", "include" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, product or equipment including a series of elements includes not only those elements, but also includes other elements that are not clearly listed, or also includes elements inherent to such process, method, product or equipment. In the absence of more restrictions, it is not excluded that there are other identical or equivalent elements in the process, method, product or equipment including the elements. For example, if the words first, second, etc. are used to represent the name, they do not represent any particular order.

Another point is that the mutual coupling or direct coupling or communication connection shown or discussed can be an indirect coupling or communication connection through some interfaces, devices or units, which can be electrical, mechanical or other forms.
