Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing 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 methods mainly include "result chaining" and "non-homogeneous evidence-based.
In view of the problems in the prior art, the present application provides a method for generating a target non-homogeneous evidence of a target block chain account by encapsulating a first hash value and a token value of the homogeneous evidence based on a preset non-homogeneous evidence-based book, so that the homogeneous evidence can be circulated among the block chain accounts by using the non-homogeneous evidence as a medium, and the target non-homogeneous evidence can have the characteristics of the non-homogeneous evidence and the homogeneous evidence at the same time; and on the basis of the target non-homogeneous general evidence, trading the non-homogeneous general evidence and/or the homogeneous general evidence in the target non-homogeneous general evidence to obtain a trading result, so that the trading result can be traced by using the non-homogeneous general evidence, and statistics and benefit distribution can be carried out by using the homogeneous general evidence, thereby realizing the traceability of the trading result and improving the reliability.
Referring to fig. 1, fig. 1 is a flowchart illustrating an implementation of a processing method for digital certification according to an embodiment of the present application. The processing method of the digital certificate disclosed in the embodiment of the application can be applied to terminal equipment, and the terminal equipment includes but is not limited to computer equipment such as a notebook, a desktop computer, a physical server and a cloud server which are built by using a block chain technology. The processing method of the digital certification according to the embodiment of the application includes steps S101 to S103, which are detailed as follows:
step S101, obtaining a certification establishing request, wherein the certification establishing request comprises a first Hash value and a token value of the homogenization certification, the first Hash value is an identification of the homogenization certification, and the token value is used for representing the number of the homogenization certification.
In this example, the homogeneous Token (FT) is a numerical Token relative to the Non-homogeneous Token (NFT). For example, the traditional electronic cash accounting mode is a homogenization certification, for example, if a user a transfers 10 yuan to the user a first, and a user B transfers 10 yuan to the user a, anyone cannot prove whether the electronic cash transferred twice is the same '10 yuan'. In contrast, banknotes are a non-homogenous evidence, because each banknote is numbered, it is easy to distinguish different "10 dollars". The first hash value is used for identifying homogenization evidence passing, and the token value is used for identifying the amount of the evidence passing.
Step S102, packaging the first Hash value and token value of the homogeneous evidence based on a preset heterogeneous evidence-passing book, and generating the target heterogeneous evidence-passing of the target block chain account.
In this embodiment, the non-homogeneous receivables ledger is a kind of characteristic ledger recorded on the blockchain. Illustratively, a blockchain account a is created using an SDK encapsulated in an application layer, and then an FT is created after blockchain account a, and an NFT is created based on FT. FT is converted into NFT by a certain proportion, and both NFT and FT are the same book at the time of creation. 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 an NFT account book.
In an embodiment, based on a preset non-homogeneous evidence-based book, the method for generating a target non-homogeneous evidence-based book of a target block chain account by encapsulating a hash value and a token value of the homogeneous evidence-based book includes: inputting the first hash value and token value of the homogeneous accreditation into a preset non-homogeneous accreditation account book to obtain a new non-homogeneous accreditation account book; generating a second hash value of the non-homogeneous certification based on the new non-homogeneous certification account book; verifying the correctness of input parameters in the non-homogeneous recertification account book, 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-homogenization pass-certificate based on the signature certificate of the target block chain account to obtain the target non-homogenization pass-certificate.
In this embodiment, the credential creating request includes a block chain account address, a first hash value, a message, and request parameters such as an FT value and a signature key that the NFT needs to include. Specifically, verifying the request parameter and the node type, checking whether the operation of creating the NFT can be initiated, if so, inputting the first hash value and the token value into the NFT book, and generating the NFT hash; after the signature key is verified, putting the NFT account book into an account book pool for waiting for processing; and when the NFT account book is executed, checking whether the final input parameters of the NFT account book are correct, and if so, signing the NFT account book to generate the NFT.
In the embodiment, the first hash value and the token value of the homogeneous general evidence are input into a preset non-homogeneous general evidence account book, so that the non-homogeneous general evidence contains the first hash value for identifying the homogeneous general evidence and the token value for representing the homogeneous general evidence number; and generating a second hash value of the non-homogeneous certificate-passing based on the new non-homogeneous certificate-passing book for identifying the non-homogeneous certificate-passing, and then ensuring data security through parameter verification and signature.
And step S103, based on the target non-homogeneous evidence, carrying out transaction on the non-homogeneous evidence and/or the homogeneous evidence in the target non-homogeneous evidence to obtain a transaction result.
In this embodiment, FT and NFT transactions can be conducted using the target non-homogenous certification. It is understood that FT transactions are processes that utilize non-homogenous credentials in the target non-homogenous credentials to conduct transactions, and NFT transactions are processes that utilize homogenous credentials in the target non-homogenous credentials to conduct transactions. The FT transaction flow process may be: and initiating transfer, verifying whether the hash value, the timestamp, the signature and the related account of the receiver account reach the balance required to be deducted, if the conditions are met, generating the output content of the transaction, such as the hash value of the transaction, the latest holder information of the homogenization certification and the latest circulation record, and finally transferring the FT to the receiver account.
By way of example and not limitation, an application scenario is provided where a government has set an incentive for a market to consume funds that are expected to be used, such as 1000 thousands, which 1000 corresponds to FT in this embodiment. The government issues funds through the blockchain to the channel, such as channel a receives 200 million, which are divided into 4 ten thousand 50 denomination (50 FT per share) of the consumption ticket (NFT). When a consumer goes to a venue for consumption, the venue party is responsible for verification and sales, and FT is allocated to the venue party account according to an intelligent contract.
In one embodiment, based on the target non-homogeneous evidence, trading the homogeneous evidence in the target non-homogeneous evidence to obtain a trading result, including: acquiring a pass-certificate transaction request, wherein the pass-certificate transaction request comprises the transaction pass-certificate quantity and a pass-certificate receiving account; and transferring the first hash value, the token value corresponding to the transaction evidence obtaining quantity and the second hash value to an evidence obtaining receiving account to obtain a transaction result.
Illustratively, the target non-homogeneous voucher is a consumption coupon, the government issues a ticket with a total price of 15 yuan to the channel party, and the channel party divides the ticket into 5 yuan consumption coupons and 10 yuan consumption coupons, so that a non-homogeneous voucher with an amount of 5 yuan and a non-homogeneous voucher with an amount of 10 blocks are respectively created, wherein the token value of the homogeneous voucher in the non-homogeneous voucher is 5 to represent the amount of the consumption coupon. Therefore, in the actual transaction, the user a consumes at the merchant B by using the 5-element consumption ticket, and the 5 elements of the user a in the blockchain need to be transferred into the merchant B, and then the blockchain transfers token ═ 5 in the homogenization voucher of the user a into the merchant B at this time.
In this embodiment, the first hash value, the token value corresponding to the transaction passing amount, and the second hash value are transferred to the pass receiving account to obtain the transaction result, so that which non-homogeneous pass is obtained can be known from the second hash value in the transaction result, the transaction amount in the transaction result can be known, and the identification code of the transaction amount can be known from the first hash value in the transaction result.
In an embodiment, the trading the homogeneous voucher in the target non-homogeneous voucher based on the target non-homogeneous voucher, and after obtaining a trading result, the method further includes: and if the final receiving account of the target non-homogeneous voucher is a target destroying account, destroying the target non-homogeneous voucher.
In this embodiment, for the rights and interests voucher such as the ticket, the ticket cannot be reused after being used, so the non-homogeneous voucher corresponding to the ticket needs to be destroyed, so that the non-homogeneous voucher is prevented from being reused, and the accuracy of the transaction result is ensured.
Each NFT is created with a final usage object and will be the final flow of the non-homogeneity evidence based on this usage object. For example, an NFT containing 50 units of FT (that is, the token value of FT is 50) is created at the address a, then after a series of circulation, the NFT finally flows to the destruction address B, at this time, a function is called to determine whether to destroy the NFT and generate a hash value of the present destruction event record, and if true is returned, the NFT is destroyed, which may be regarded as the verification and cancellation of the NFT.
In an embodiment, after destroying the target non-homogeneity certification, the method further includes: and transferring the homogenization general evidence in the non-homogenization general evidence to a preset block chain account.
In this embodiment, the homogenous certificates are released for creation of new non-homogenous certificates, and recycling is achieved.
In an embodiment, the trading the homogeneous voucher in the target non-homogeneous voucher based on the target non-homogeneous voucher, and after obtaining a trading result, the method further includes: acquiring an intelligent contract, wherein the intelligent contract comprises a benefit distribution strategy; and based on the benefit distribution strategy, distributing the benefits corresponding to the received token value to the certificate receiving account according to the certificate receiving account and the received token value of the non-homogeneous certificate in the transaction result.
In this embodiment, NFT may be destroyed by following a certain smart contract, and the released FT may make a directional transition under the control of the smart contract rules. For example, if the NFT is known to have circulated three account addresses once through query, the last released FT can be equally distributed to three accounts through the intelligent contract rule, for example, the benefit distribution of the badminton merchant to promote the consumption ticket.
An intelligent contract may be understood as a ledger on a blockchain, with code automatically executing once an event triggers a term in the contract. Illustratively, the intelligent contract implementation flow of the certification distribution is as follows:
a field called 'attribute' is added in the NFT, which reflects the type of NFT currently created, for example, 1 represents badminton. Each time the system receives a verification and cancellation request of the NFT, the system can directly call the badminton intelligent contract to allocate the FT. Meanwhile, when creating the NFT, it may be input which intelligent contract function the NFT defaults to call, and at the same time, which kind of contract ID the NFT supports, and create the type of the NFT (i.e., "attribute"), and fill in this type in the jason format by using the programmable book.
In addition to entering the "attribute" field for NFT and making an intelligent contract containing a certain rule, it is more important to establish the correspondence between type and contract (verification and sale rule) to be effective on each of the badminton tickets, and this correspondence can be written on another intelligent contract and can be directly called when in use.
In the embodiment, because the token receiving account of the non-homogeneous voucher and the token value of the received homogeneous voucher are recorded in the transaction result, the non-homogeneous voucher benefit distribution can be performed based on the non-homogeneous voucher, and statistics can be performed based on the homogeneous voucher, so that benefit distribution is facilitated.
In an embodiment, the transaction result includes a first hash value and a second hash value, and the transaction is performed on the homogeneous voucher in the target non-homogeneous voucher based on the target non-homogeneous voucher, and after the transaction result is obtained, the method further includes: and tracing the non-homogenization evidence based on the second hash value in the transaction result to obtain a circulation record of the non-homogenization evidence.
In this embodiment, NFT is combined with a real-existing consumption ticket to clarify ownership and realize value storage, and is applied to tracing and storing value of a value product, so that NFT becomes a main carrier of the consumption ticket. Illustratively, a set of traceability systems is designed for NFT, and the process is as follows: NFT flows over multiple accounts, eventually being credited at an account (assuming the account is D); calling a function to inquire whether the NFT is from an account C through the NFT identifier with the owner being D; with pointers, indexing is continued up, tracing back to the oldest created NFT, characterized by its lack of previous source of NFT.
Then, the NFT trace back process established by user A, B, C, D is shown in fig. 4, all trace back data of the whole process will be stored together by user A, B, C, D, and other users in the system can access the data of this chain only after authorization. In this embodiment, the non-homogenization certification is traced through the second hash value, so that the circulation records of the non-homogenization certification in each block chain account can be obtained.
