Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.
As described in the related background art, the current ticket processing method is mainly "result uplink" and "on-link non-homogeneous pass", but the non-homogeneous pass cannot be overlapped and split, which is unfavorable for benefit distribution, and the homogeneous pass cannot be traced.
Aiming at the problems in the prior art, the application provides a method for generating a target non-homogeneous pass of a target blockchain account by packaging a first hash value and a token value of a homogeneous pass based on a preset non-homogeneous pass account, so that the homogeneous pass can circulate among blockchain accounts with the non-homogeneous pass as a medium, and the target non-homogeneous pass has the characteristics of both the non-homogeneous pass and the homogeneous pass; and based on the target non-homogeneous pass, carrying out transaction on the non-homogeneous pass and/or the homogeneous pass in the target non-homogeneous pass to obtain a transaction result, so that the transaction result can be traced by utilizing the non-homogeneous pass and can be counted and benefit distributed by utilizing the homogeneous pass, thereby realizing traceability of the transaction result and improving the credibility.
Referring to fig. 1, fig. 1 shows a flowchart of an implementation of a method for processing digital certificates according to an embodiment of the present application. The method for processing the digital certificate in the embodiment of the application can be applied to terminal equipment, wherein the terminal equipment comprises, but is not limited to, computer equipment such as a notebook computer, a desktop computer, a physical server, a cloud server and the like which are built by using a block chain technology. The processing method of the digital certificate in the embodiment of the application comprises the steps S101 to S103, and is described in detail as follows:
step S101, acquiring a pass creation request, wherein the pass creation request comprises a first hash value of a homogeneous pass and a token value, the first hash value is an identification of the homogeneous pass, and the token value is used for representing the number of the homogeneous pass.
In this example, the homogeneous pass (Fungible Token, FT) is a digital pass relative to the heterogeneous pass (Non-Fungible Token, NFT). For example, the traditional accounting method of electronic cash is a homogeneous certificate, for example, if user a transfers 10 yuan to user a and then user B transfers 10 yuan to user a, any person cannot prove whether the electronic cash transferred twice is the same "10 yuan". In contrast, a banknote is a non-homogeneous pass because each banknote has a number that can easily distinguish between different "10" digits. The first hash value is used for identifying the homogenization pass, and the token value is used for identifying the pass number.
Step S102, based on a preset heterogeneous communication account book, packaging a first hash value and a token value of the homogeneous communication account, and generating a target heterogeneous communication account of the target blockchain account.
In this embodiment, the non-homogeneous general ledger is a type of feature ledger recorded on the blockchain. Illustratively, the blockchain account a is created with the SDK encapsulated at the application layer, the FT is created after the blockchain account a, and an NFT is created on the basis of the FT. FT is converted to NFT by a certain ratio, both NFT and FT being the same ledger at creation time. In the process of creating the NFT, the hash value of the original FT and the number of tokens to be converted need to be input on the NFT ledger.
In an embodiment, based on a preset heterogeneous universal certificate account book, packaging a hash value and a token value of a homogeneous universal certificate to generate a target heterogeneous universal certificate of a target blockchain account, including: inputting the first hash value and the token value of the homogenization pass into a preset non-homogenization pass account book to obtain a new non-homogenization pass account book; generating a second hash value of the heterogeneous general evidence based on the new heterogeneous general evidence ledger; verifying the correctness of input parameters in the non-homogeneous general ledger, wherein the input parameters comprise a first hash value, a token value and a second hash value; and if the input parameters are correct, signing the non-homogeneous pass based on the signature certificate of the target blockchain account to obtain the target non-homogeneous pass.
In this embodiment, the license creation request includes request parameters such as a blockchain account address, a first hash value, a message, an FT value that the NFT needs to include, and a signature key. Specifically, verifying request parameters and node types, checking whether an operation of creating the NFT can be initiated, if so, inputting a first hash value and a token value into an NFT account book, and generating an NFT hash; after verifying the signature secret key, placing the NFT account book into an account book pool for waiting to be processed; and when the NFT account book is executed, checking whether final input parameters of the NFT account book are correct, and signing the NFT account book if the final input parameters are correct to generate the NFT.
The first hash value and the token value of the homogenization pass are input into a preset non-homogenization pass account book, so that the non-homogenization pass contains the first hash value for identifying the homogenization pass and the token value for representing the number of the homogenization passes; and generating a second hash value of the non-homogeneous pass certificate based on the new non-homogeneous pass certificate so as to be used for identifying the non-homogeneous pass certificate, and then verifying and signing through parameters to ensure the data security.
Step S103, based on the target non-homogeneous pass, carrying out transaction on the non-homogeneous pass and/or the homogeneous pass in the target non-homogeneous pass to obtain a transaction result.
In this embodiment, FT transactions and NFT transactions can be performed using target non-homogeneous pass. It is understood that FT transactions are processes that utilize non-homogeneous ones of the target non-homogeneous passes to conduct transactions, and NFT transactions are processes that utilize homogeneous ones of the target non-homogeneous passes to conduct transactions. The FT transaction flow process may be: initiating transfer, verifying whether the hash value, the timestamp, the signature and the related account of the receiver account reach the balance to be deducted, if the conditions are met, generating output contents of the transaction, such as the hash value of the transaction, the latest holder information and the latest circulation record of the homogenization pass, and finally transferring FT to the receiver account.
By way of example and not limitation, an application scenario is provided in which government settings stimulate funds expected to be used by market consumers, such as 1000 ten thousand, which 1000 ten thousand corresponds to FT in this embodiment. The government issues funds to the channel through the blockchain, e.g., channel a receives 200 tens of thousands, dividing it into 4 tens of thousands of 50 denominations (50 FT per serving) of consumer coupons (NFT). When a consumer goes to a venue for consumption, the venue party is responsible for verifying the approval and assigning the FT to the venue party account according to the smart contract.
In an embodiment, based on the target non-homogeneous pass, performing a transaction on the homogeneous pass in the target non-homogeneous pass to obtain a transaction result, including: acquiring a pass transaction request, wherein the pass transaction request comprises a transaction pass quantity and a pass receiving account; and transferring the first hash value, the token value corresponding to the transaction verification quantity and the second hash value to a verification receiving account to obtain a transaction result.
Illustratively, the target non-homogeneous pass is a consumption ticket, the government issues a ticket with a total value of 15 yuan to the channel party, the channel party divides the ticket into 5 yuan and 10 yuan consumption tickets, and then a non-homogeneous pass with a5 yuan amount and a non-homogeneous pass with a 10 piece amount are respectively created, wherein the token value of the homogeneous pass in the non-homogeneous pass is 5 to represent the amount of the consumption ticket. Therefore, in actual transaction, when the user a consumes at the merchant B using the 5-membered consumption coupon, the 5-membered of the user a in the blockchain needs to be transferred to the merchant B, and then the blockchain transfers token=5 in the homogeneity of the user a to the merchant B.
In this embodiment, the transaction result is obtained by transferring the first hash value, the token value corresponding to the transaction verification number, and the second hash value to the verification receiving account, so that which non-homogeneous verification is obtained from the second hash value in the transaction result, the transaction amount in the transaction result can be obtained, and the identification code of the transaction amount can be obtained from the first hash value in the transaction result.
In an embodiment, based on the target non-homogeneous pass, performing a transaction on the homogeneous pass in the target non-homogeneous pass, and after obtaining a transaction result, further including: if the final receiving account of the target non-homogeneous pass is a target destroying account, destroying the target non-homogeneous pass.
In this embodiment, for the equity certificates such as the ticket, the ticket cannot be reused after use, so the non-homogeneous pass corresponding to the ticket needs to be destroyed, so that the non-homogeneous pass is prevented from being reused, and the accuracy of the transaction result is ensured.
Each NFT has an end use object before creation and will use the object as the last flow for the non-homogenous pass based on this. For example, address a creates an NFT containing 50 units FT (i.e., the token value of FT is 50), then after a series of flows, the NFT finally flows to destruction address B, at which time a function is called to confirm whether to destroy and generate a hash value of the current destruction event record, and if true is returned, the NFT is destroyed, and the process can be understood as the verification of the NFT.
In an embodiment, after destroying the target heterogeneous certificate, further comprising: and transferring the homogenization pass in the non-homogenization pass to a preset blockchain account.
In this embodiment, the homogenous communication is released for creating a new non-homogenous communication, so as to realize recycling.
In an embodiment, based on the target non-homogeneous pass, performing a transaction on the homogeneous pass in the target non-homogeneous pass, and after obtaining a transaction result, further including: acquiring an intelligent contract, wherein the intelligent contract comprises a benefit distribution strategy; based on the benefit distribution strategy, according to the credit receipt account and the received token value of the non-homogeneous credit in the transaction result, distributing the benefit corresponding to the received token value to the credit receipt account.
In this embodiment, the NFT may adhere to a certain intelligent contract to be destroyed, and the released FT may perform directional transfer under the control of the intelligent contract rule. Knowing that the NFT has been streamed through three account addresses, for example, by querying, the last released FT can be evenly distributed to three accounts by the smart contract rules, for example, the benefit distribution for the consumer coupon promotion by a badminton merchant.
An intelligent contract can be understood as an account book on a blockchain, with code executing automatically upon some event triggering a term in the contract. Illustratively, the smart contract implementation flow for the certification distribution is as follows:
A field called "attribute" is added to the NFT that reflects the type of NFT currently being created, such as 1 for shuttlecocks. And each time the system receives a verification request of the NFT, the system can directly call the badminton intelligent contract to distribute FT. Meanwhile, when the NFT is created, it can input which intelligent contract function the NFT defaults to call, and at the same time, the NFT supports the IDs of which contracts, the type (i.e. "attribute") of the NFT is created, and the type is filled in by jason format by using the programmable ledger.
In addition to entering an "attribute" field for the NFT and formulating an intelligent contract containing a rule, more importantly, a correspondence between the type and the contract (a validation rule) is established, and the correspondence is validated on each shuttlecock ticket, and the correspondence can be written on another intelligent contract and can be directly invoked when in use.
In this embodiment, since the transaction result records the token receiving account of the non-homogeneous token and the token value of the received homogeneous token, the transaction result can be distributed based on the benefits of the non-homogeneous token, and statistics can be performed based on the homogeneous token, thereby being beneficial to realizing benefits distribution.
In an embodiment, the transaction result includes a first hash value and a second hash value, and based on the target non-homogeneous pass, the method further includes, after obtaining the transaction result, performing a transaction on a homogeneous pass in the target non-homogeneous pass: and tracing the non-homogeneous pass based on the second hash value in the transaction result to obtain a circulation record of the non-homogeneous pass.
In this embodiment, the NFT is combined with the existing consumption ticket, so that the NFT is explicitly entitled to and stored in the real consumption ticket, and the NFT is applied to tracing and storing a value product, so that the NFT becomes a main carrier of the consumption ticket. Illustratively, a set of traceability system is designed for NFT, and the procedure is as follows: NFT flows over multiple accounts, eventually being revoked at an account (assuming the account is D); calling a function to inquire that the NFT is sourced from an account C through the NFT identification of which the owner is D; with the pointer, index up is continued, tracing back to the earliest created NFT, which is characterized by the absence of the last NFT source.
Then, as shown in fig. 4, the NFT trace back process established by the user A, B, C, D, all trace back data of the entire process will be stored together by the user A, B, C, D, and other users in the system can access the data of this chain only after being authorized. According to the embodiment, the non-homogeneous pass is traced through the second hash value, so that the circulation records of the non-homogeneous pass in each blockchain account can be obtained.
