Description

Technical Field

[0001] The present invention relates to the field of computing power resource trading methods, and specifically to a computing power resource trading method and system based on NFT. Background Art

[0002] With the development of the digital economy, computing power has gradually become a new productivity, and the demand for computing power has also exploded. Due to the uneven distribution of computing power resources, some regions have excess computing power, while other regions may face a shortage of computing power, so computing power resource transactions came into being.

[0003] Computing resource trading refers to the act of buying, selling or sharing computing resources. The existing trading methods of computing resources include direct trading, trading through computing trading platforms, and trading through blockchain. Compared with the other two methods, the blockchain trading method has higher transaction transparency and security due to its decentralized characteristics, so it has developed rapidly in computing resource trading.

[0004] However, although the existing technology has used blockchain transactions to trade computing resources, it only ensures the transparency and security of transactions through blockchain technology. There are still problems such as low utilization and waste of computing resources, making it difficult to achieve reasonable allocation of computing resources. Summary of the invention

[0005] The present invention provides a computing power resource trading method and system based on NFT to solve the problem of difficulty in achieving reasonable resource allocation when computing power resource trading is realized through blockchain technology in the prior art.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] The NFT-based computing power resource trading method has the following process:

[0008] Obtain key attribute information of computing resources provided by the computing power provider, as well as encrypted data A and symmetric key A, wherein the key attribute information includes the provider ID and the time range of resource availability, and the encrypted data A is obtained by encrypting the computing power access credential by the computing power provider using the symmetric key A;

[0009] Divide the resource available time range in the key attribute information into multiple lease time periods, decrypt the encrypted data A with the symmetric key A to obtain the computing power access credential, and use the computing power access credential to encrypt each lease time period and then splice it with the corresponding lease time period to obtain the lease access credential with a time limit corresponding to each lease time period, and then use the symmetric key A to encrypt the lease access credential to obtain the encrypted data C;

[0010] Construct computing power leasing NFT metadata for each leasing period, including each leasing period and its corresponding encrypted data C, and generate a unique identifier for the computing power leasing NFT metadata, then store the computing power leasing NFT metadata on the NFT computing power public chain and obtain the storage path of the computing power leasing NFT metadata, and then use the unique identifier, storage path, and provider ID of the computing power leasing NFT metadata to cast a computing power leasing NFT on the NFT computing power public chain;

[0011] Finally, the computing power leasing NFT is traded with the buyer on the NFT computing power public chain. During the transaction, based on the computing power leasing NFT purchased by the buyer, it is determined whether the buyer's required rental time is within the rental time period corresponding to the purchased computing power leasing NFT. If it is not within the rental time period, the transaction is invalid. If it is within the rental time period, the transaction is established. When the transaction is established, the buyer's wallet public key is obtained, and the symmetric key A is encrypted by the buyer's wallet public key to obtain the encrypted data D, and the encrypted data D and the encrypted data C in the computing power leasing NFT purchased by the buyer are sent to the buyer.

[0012] Furthermore, after obtaining the symmetric key A, the symmetric key A is encrypted using the symmetric key B to form encrypted data B; the computing power metadata is constructed using the key attribute information, encrypted data A, and encrypted data B, a unique identifier is generated for the computing power metadata, and then the computing power metadata is stored on the NFT computing power public chain and the storage path of the computing power metadata is obtained, and then the unique identifier, storage path, and provider ID of the computing power metadata are used to cast the computing power original NFT on the NFT computing power public chain to prove the computing power provider's ownership of the computing power resources;

[0013] When the transaction is established, the encrypted data B in the original NFT of the computing power is decrypted by the symmetric key B to obtain the symmetric key A, and then the symmetric key A is encrypted using the buyer's wallet public key to obtain the encrypted data D.

[0014] Furthermore, the computing power leasing NFT metadata also includes a unique identifier of the computing power metadata.

[0015] Furthermore, the key attribute information also includes a time granularity of the lease, and the available time range of the resource is divided into a plurality of lease time periods according to the time granularity.

[0016] Furthermore, the key attribute information also includes a baseline price for each time granularity, and the computing power leasing NFT metadata also includes a baseline price for each time granularity.

[0017] The NFT-based computing power resource trading system includes a computing power public chain module, a smart contract module, and an NFT management module, which are used to implement the above-mentioned NFT-based computing power resource trading method, wherein:

[0018] The computing power public chain module generates an NFT computing power public chain;

[0019] The smart contract module generates a computing power resource management contract on the NFT computing power public chain. The computing power resource management contract obtains the key attribute information of the computing power resources, the symmetric key A, and the encrypted data A from the computing power provider, and sends them to the NFT management module;

[0020] The NFT management module divides the resource available time range in the key attribute information into multiple lease time periods, generates the lease access credential corresponding to each lease time period, and obtains the encrypted data C based on the lease access credential;

[0021] The NFT management module also constructs the computing power leasing NFT metadata and casts the computing power leasing NFT on the NFT computing power public chain;

[0022] The computing power resource management contract trades the computing power rental NFT with the buyer on the NFT computing power public chain, and during the transaction, the computing power resource management contract determines whether the buyer's required rental time is within the rental time period corresponding to the purchased computing power rental NFT. When the transaction is established, the computing power resource management contract obtains the encrypted data D and sends the encrypted data D and the encrypted data C in the computing power rental NFT purchased by the buyer to the buyer.

[0023] Furthermore, after the computing power resource management contract obtains the symmetric key A, the computing power resource management contract uses the symmetric key B to encrypt the symmetric key A to form encrypted data B; when the transaction is established, the computing power resource management contract decrypts the encrypted data B in the original NFT of the computing power to obtain the symmetric key A.

[0024] Furthermore, the NFT management module also constructs computing power metadata with the key attribute information, encrypted data A, and encrypted data B, and casts the computing power original NFT on the NFT computing power public chain.

[0025] Furthermore, when the NFT management module divides the multiple lease time periods, the resource available time range is divided into multiple lease time periods according to the time granularity in the key attribute information.

[0026] Furthermore, the computing power leasing NFT metadata constructed by the NFT management module also includes a baseline price for each time granularity.

[0027] In the present invention, the available time range of computing power resources is divided into multiple rental time periods according to the available time range of resources in the key attribute information provided by the computing power provider, and a corresponding computing power rental NFT is generated for each time period, and the transaction of computing power resources is realized between the computing power rental NFT and the buyer. In this way, the allocation of computing power resources can be strictly implemented according to the rental time period during the transaction, thereby avoiding the idleness of computing power resources and the waste problem caused by the buyer not using the computing power resources for a long time after purchasing the computing power resources.

[0028] In addition, in the present invention, an original NFT of computing power is generated for the computing power provider, and the NFT blockchain technology is used to prove the ownership of the computing power provider to the computing power resources, thereby effectively protecting the interests of the computing power provider.

[0029] Compared with the existing technology, the present invention combines NFT blockchain and smart contract technology to build an efficient and transparent computing power trading method. Users can rent computing power resources conveniently and flexibly, which not only ensures the security and transparency of computing power resource transactions, but also realizes the reasonable allocation of computing power resources and avoids idleness and waste of computing power resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Figure 1 It is a flowchart of a method according to an embodiment of the present invention. DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the solutions of the present invention, the following will describe the implementation methods of the present invention in detail in conjunction with the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve corresponding technical effects can be fully understood and implemented accordingly. The embodiments of the present invention and the various features in the embodiments can be combined with each other without conflict, and the technical solutions formed are all within the protection scope of the present invention.

[0032] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0033] It should be noted that the terms "include" and "have" in the specification and claims of the present invention and the above drawings and any modifications thereof are intended to cover non-exclusive inclusions.

[0034] like Figure 1 As shown, this embodiment discloses a computing power resource trading method based on NFT, and the process is as follows:

[0035] First, obtain the key attribute information of computing resources, encrypted data A, and symmetric key A from the computing power provider. Among them, the key attribute information includes the provider ID, computing resource information, resource available time range, rental time granularity, and baseline price of each time granularity. The computing resource information includes resource ID, CPU model, GPU model, computing power, memory size, storage size, and geographic location. In addition, the computing power provider uses the symmetric key A to encrypt the computing access credentials for accessing the computing resources, and obtains the encrypted data A.

[0036] After obtaining key attribute information, encrypted data A, and symmetric key A, symmetric key A is encrypted using symmetric key B to obtain encrypted data B.

[0037] In addition, according to the resource available time range and the time granularity of the lease in the key attribute information, the resource available time range is cut according to the time granularity, so that the resource available time range is divided into multiple lease time periods. The computing power access credential is obtained by decrypting the encrypted data A with the symmetric key A, and each lease time period is encrypted with the computing power access credential and then spliced ​​with the corresponding lease time period to obtain the lease access credential with a time limit corresponding to each lease time period, and then the lease access credential is encrypted with the symmetric key A to obtain the encrypted data C. Thus, the corresponding lease access credential is generated for each lease time period and the corresponding encrypted data C is formed.

[0038] Then, the original NFT of computing power and the NFT of computing power leasing corresponding to each leasing period are minted. The original NFT of computing power minting process is as follows:

[0039] The key attribute information, encrypted data A, and encrypted data B are constructed into computing power metadata in json format, and after generating a unique identifier tokenid1 for the computing power metadata, the computing power metadata is stored on the NFT computing power public chain to obtain the storage path of the computing power metadata, and then the unique identifier tokenid1, storage path, and provider ID of the computing power metadata are used to cast on the NFT computing power public chain to form the computing power original NFT. The computing power original NFT is not traded, and is only used on the NFT computing power public chain to prove the ownership of the computing power provider to the computing power resources.

[0040] The NFT minting process of computing power leasing is as follows:

[0041] The computing power leasing NFT metadata in json format is constructed with the unique identifier tokenid1 of the computing power metadata, the leasing time period, the baseline price of each time granularity, and the encrypted data C. After generating the unique identifier tokenid2 for the computing power leasing NFT metadata, the computing power leasing NFT metadata is stored on the NFT computing power public chain and the storage path of the computing power leasing NFT metadata is obtained. Then, the unique identifier tokenid2, storage path, and provider ID of the computing power leasing NFT metadata are used to cast on the NFT computing power public chain to form a computing power leasing NFT. The computing power leasing NFT is used as a trading currency for buyers to trade on the NFT computing power public chain.

[0042] Finally, the computing power leasing NFT is put up for sale on the NFT computing power public chain. When the buyer purchases the computing power leasing NFT through the NFT computing power public chain, the buyer's required rental time is obtained, and the corresponding rental time period is obtained according to the computing power leasing NFT purchased by the buyer. Then, it is determined whether the buyer's required rental time is within the rental time period corresponding to the purchased computing power leasing NFT. If the judgment result is not within the rental time period, the transaction is invalid. If the judgment result is within the rental time period, the transaction is established.

[0043] When the transaction is established, the buyer's wallet public key is obtained, and the encrypted data B in the original NFT of the computing power is decrypted by the symmetric key B to obtain the symmetric key A, and then the symmetric key A is encrypted with the buyer's wallet public key to obtain the encrypted data D. Finally, the encrypted data D and the encrypted data C in the computing power rental NFT purchased by the buyer are sent to the buyer.

[0044] After the buyer obtains encrypted data C and encrypted data D, he uses his wallet private key to decrypt encrypted data D and obtains symmetric public key A. He then uses symmetric public key A to decrypt encrypted data C and obtains a lease access credential with a time limit. He then uses the lease access credential with a time limit to access and call computing resources during the corresponding lease period. Thus, the entire computing resource transaction process is completed.

[0045] When the buyer visits, the computing power provider's computing power resources use the computing power access credentials to decrypt the rental access credentials provided by the buyer to obtain the rental time period, and check whether the rental time period is within the resource availability time range provided by the provider. If it is within the resource availability time range, the computing power provider allows the buyer to access and call the computing power resources.

[0046] This embodiment also discloses an NFT-based computing resource trading system for implementing the above-mentioned computing resource trading method, including a computing power public chain module, a smart contract module, and an NFT management module, wherein:

[0047] The computing power public chain module generates the NFT computing power public chain and selects the appropriate consensus mechanism (such as proof of stake or proof of work, etc.) to ensure the security and efficiency of the public chain. The nodes of the NFT computing power public chain allow multiple participants (such as computing power providers) to access the network to ensure the decentralization of the system. The trading rules of computing power resources, the NFT generation mechanism and the profit distribution logic are also defined on the NFT computing power public chain.

[0048] The smart contract module generates a computing power resource management contract on the NFT computing power public chain, and computing power providers and buyers trade computing power resources through the computing power resource management contract on the NFT computing power public chain.

[0049] Specifically, the computing power resource management contract obtains the key attribute information of the computing power resource, symmetric key A, and encrypted data A from the computing power provider, and the computing power resource management contract uses symmetric key B to encrypt symmetric key A to form encrypted data B. Encrypted data A and encrypted data B are both stored in the computing power resource management contract. The private key of symmetric key B of the computing power resource management contract is not exposed to the outside world and can only be read and used by this contract. In addition, the computing power resource management contract sends the obtained key attribute information, symmetric key A, encrypted data A, and encrypted data B to the NFT management module.

[0050] The NFT management module divides the resource availability time range into multiple lease time periods according to the resource availability time range and lease time granularity in the key attribute information. The NFT management module decrypts the encrypted data A with the symmetric key A to obtain the computing power access credential, and uses the computing power access credential to encrypt each lease time period and then splices it with the corresponding lease time period to obtain the lease access credential with a time limit corresponding to each lease time period. The NFT management module then uses the symmetric key A to encrypt each lease access credential to obtain the encrypted data C.

[0051] The NFT management module also constructs the key attribute information, encrypted data A, and encrypted data B into computing power metadata in json format, and after generating a unique identifier tokenid1 for the computing power metadata, it stores the computing power metadata on the NFT computing power public chain to form a distributed storage that only the NFT management module has the operation authority to, and obtains the storage path of the computing power metadata. The NFT management module then uses the unique identifier tokenid1, storage path, and provider ID of the computing power metadata to cast on the NFT computing power public chain according to the NFT generation mechanism to form the computing power original NFT.

[0052] The NFT management module also uses the unique identifier tokenid1 of the computing power metadata, the rental time period, the baseline price of each time granularity, and the encrypted data C to construct the computing power leasing NFT metadata in json format, and after generating the unique identifier tokenid2 for the computing power leasing NFT metadata, the computing power leasing NFT metadata is stored on the NFT computing power public chain to form a distributed storage that only the NFT management module has the operation authority to, and obtain the storage path of the computing power leasing NFT metadata. The NFT management module then uses the unique identifier tokenid2, storage path, and provider ID of the computing power leasing NFT metadata to cast it on the NFT computing power public chain according to the NFT generation mechanism to form a computing power leasing NFT.

[0053] Therefore, in this embodiment, the NFT management module casts the computing power original NFT and multiple computing power leased NFTs on the NFT computing power public chain, wherein the computing power original NFT is not routinely traded, and multiple computing power leased NFTs are provided to buyers for trading.

[0054] The NFT management module delivers the obtained computing power leasing NFT to the computing power resource management contract. The computing power provider sells the computing power leasing NFT on the NFT computing power public chain through the computing power resource management contract.

[0055] When a buyer trades a computing power rental NFT, the computing power resource management contract obtains the buyer's required rental time, and obtains the corresponding rental time period based on the computing power rental NFT purchased by the buyer. It then determines whether the buyer's required rental time is within the rental time period corresponding to the purchased computing power rental NFT. If the judgment result is that it is not within the rental time period, the transaction is invalid. If the judgment result is that it is within the rental time period, the transaction is established.

[0056] When the transaction is established, the computing power resource management contract obtains the buyer's wallet public key. The computing power resource management contract also finds the encrypted data B according to the storage path of the computing power metadata in the original computing power NFT, and finds the encrypted data C according to the storage path of the computing power rental NFT metadata in the computing power rental NFT purchased by the buyer. In addition, the computing power resource management contract decrypts the encrypted data B with the symmetric key B to obtain the symmetric key A, and then uses the buyer's wallet public key to encrypt the symmetric key A to obtain the encrypted data D. Finally, the computing power resource management contract sends the encrypted data D and the encrypted data C in the computing power rental NFT purchased by the buyer to the buyer.

[0057] Finally, the buyer uses his wallet private key to decrypt the encrypted data D to obtain the symmetric public key A, and then uses the symmetric public key A to decrypt the encrypted data C to obtain a lease access credential with a time limit, and uses the lease access credential with a time limit to access and call computing power resources during the corresponding lease period, thereby completing the computing power resource transaction between the buyer and the computing power provider.
