Detailed Description
The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention.
It should be noted that the drawings provided in the present embodiment are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
The digital asset transaction method, the digital asset transaction system, the storage medium and the digital currency system are directly bound and butted with the digital currency through the digital asset elements, and the bidirectional circulation transaction data of the digital asset and the digital currency are associated and fused, so that the method is more real, compliant and authoritative, is convenient for tracing and determining the digital asset in the whole society and digging and utilizing the credible transaction data, and has high practicability.
As shown in FIG. 1, in one embodiment, the digital currency based digital asset transaction method of the present invention comprises the following steps:
and step S1, acquiring digital asset token information provided by the digital asset purchasing terminal through the digital asset transaction system, wherein the digital asset token information comprises a digital asset token and signature information.
In particular, a digital asset token (token) is a process that digitally represents an asset or ownership of an asset. Digital asset tokens represent assets or ownership of assets, which assets may be currency, commodities, securities, or real estate. The digital asset token is a digital asset tokenization pricing method, which comprises data such as identification codes, ownership, asset abstract, pricing method/algorithm, time, value and the like of digital assets, and is used for realizing refined digital control on the digital assets. Preferably, the token process of the important digital assets requires a third party public institution to sign and perform authority ownership identity and signature verification.
When the digital asset selling terminal needs to sell the digital asset, the digital asset selling seller provides digital asset token information consisting of the digital asset token and the signature information to the digital asset purchasing terminal in an offline or online mode. And the digital asset purchasing terminal initiates digital asset transaction, signs the digital asset token information by using a private key of the digital asset purchasing terminal, provides the digital asset token information for a digital asset transaction system, and sends the digital asset token information to the digital currency system through the digital asset transaction system.
And step S2, verifying the digital asset token information and verification information provided by the digital asset transaction system.
First, the digital asset transaction system verifies the digital asset token information and generates verification information.
Specifically, after the digital asset transaction system receives the digital asset token information, the digital asset token information needs to be verified to determine the reliability of the digital asset transaction. And the digital asset token information is verified to show that the two transaction parties agree on the digital asset transaction, and the parties can perform the subsequent digital asset transaction steps.
In one embodiment of the present invention, the verifying the digital asset token information by the digital asset transaction system comprises the steps of:
21) verifying the validity of the signature information of the digital asset purchase terminal.
Specifically, the digital asset transaction system verifies the validity of the signature information using a public key of the digital asset purchaser.
22) And acquiring digital asset token information provided by the digital asset selling terminal.
Specifically, after receiving the digital asset token information provided by the digital asset purchase terminal, the digital asset transaction system sends transaction confirmation information to the digital asset selling terminal, and sends digital asset token information request information to the digital asset selling terminal. The digital asset selling terminal provides digital asset token information to the digital asset transaction system.
23) And verifying the validity of the signature information of the digital asset selling terminal.
Specifically, the digital asset transaction system verifies the validity of the signature information using a public key of the digital asset seller.
24) Comparing the digital asset token of the digital asset purchase terminal with the digital asset token of the digital asset sale terminal for consistency.
Specifically, the digital asset transaction system compares the digital asset tokens respectively provided by the digital asset selling terminal and the digital asset purchasing terminal, and judges the consistency of the two, such as the consistency of the asset abstract and the information.
Secondly, after the digital currency system receives the digital asset token information and the verification information provided by the digital asset transaction system together with the transaction request through signature, secondary verification and verification are carried out on the digital asset token information and the verification information, wherein the secondary verification and verification comprise token information compliance and security, and the validity and the consistency of the transaction request, the token information and the digital currency wallets of the selling party and the purchasing party. Subsequent digital asset transactions are conducted only after the verification is passed.
And step S3, after the verification is passed, the digital asset token is stored in the extended attribute of the digital currency and/or the associated intelligent contract acquired by the digital asset selling terminal.
Specifically, after the digital asset transaction system first verifies the digital asset token, the digital asset transaction system submits the digital asset token to the digital currency system through an interface between the digital asset transaction system and the digital currency system, and after the digital asset token is verified again by the digital currency system, the digital asset token is stored in an extended attribute of a destination currency newly generated by transaction (namely, the digital currency acquired by the digital asset selling terminal) or in an intelligent contract associated with the digital currency. The digital currency is the value acquired by the original digital asset owner (by exchanging digital asset ownership rights). A new digital asset owner may generate a new digital asset token from a transaction data record or the like, which may contain the digital asset's original digital asset token identification to represent the source of value of the digital asset. It should be noted that the digital asset token can only be recorded into extended attributes or associated smart contracts of digital currency when generating the digital currency.
When the digital assets are transacted subsequently, the owner of the digital assets generated in the previous transaction can reach a new digital asset token of the digital assets and sign with a new transaction party. In addition, optionally, all legal identities of the digital assets need a third-party public institution, and the new transaction is started after the third-party public institution confirms and signs the digital assets by using information such as digital currency transaction data and the like.
In an embodiment of the present invention, the digital-currency-based digital asset transaction method further includes a query function for providing data of a bidirectional circulation chain of the digital asset and the digital currency. Specifically, by using the digital asset original digital asset token information submitted by the current digital asset owner and/or the old currency paid for the original purchased digital asset, etc., or the digital asset token obtained from the current owner submitted by the digital asset buyer, the digital currency system can inquire the digital asset and digital currency bidirectional circulation chain data, and the going digital currency (already belonging to the original asset owner digital wallet) paid out from the latest transaction (or appointed inquiry transaction period) of the current transaction digital asset owner wallet or the associated smart contract reads the digital asset token, namely, in the digital currency system, the current digital asset owner digital wallet is inquired in a specific transaction time interval, the going currency corresponding to the wasted digital currency (source currency) is traced back in turn until the corresponding digital asset token is found, and executing corresponding digital asset token content, such as a pricing algorithm and the like, automatically pricing again in real time, and starting subsequent associated transaction after confirmation by both transaction parties.
If the digital asset token of the original transaction digital currency is not found or the identity and signature of the verification history holder are inconsistent, the digital asset token submitted by the current owner and/or buyer is an invalid digital asset token which is not transacted, and the system does not support continuous inquiry and (subsequent) transaction. Aiming at some digital assets with important tracking value, each transaction is automatically priced based on the original digital asset token pricing algorithm/mode, and a fair and reasonable digital asset increment or decrement can be calculated by a transaction system (or a digital currency system) based on an authoritative and reliable transaction chain. If a new digital asset token is provided for a subsequent transaction, the new digital asset token is stored in an extended attribute of the newly generated digital currency or in an associated smart contract, otherwise, only the original digital asset token identification is stored in the newly generated going currency. Therefore, the digital asset tracing and the right confirming can be supported according to the credible transaction chain of the digital asset by utilizing the chain data of the bidirectional fusion of the digital asset token and the currency recorded by the digital currency system; whether the traded asset originally creates copyright can be confirmed based on the information such as the abstract and the signature contained in the digital asset token; the digital asset owner can trace and trace all transaction chains of the digital asset by submitting the original token information of the digital asset and/or old coins paid by original purchasing of the digital asset and the like, obtain the summary information of the digital asset in each link and check the original copyright authenticity of the transacted digital asset; the method can realize the controlled anonymous transaction data sharing of the digital assets and digital currencies in the whole society, avoid the theft and abuse of the data assets and obtain illegal values through the transaction.
The digital currency based digital asset transaction system of the present invention is further illustrated by the specific examples below.
As shown in FIG. 2, in this embodiment, user A has a digital asset that is just passed by a third party to form a digitized asset token; the digital asset token includes data such as an identification code of the digital asset, all rights, an asset digest, a pricing method/algorithm, time, value, etc. This data is signed by a third party public authority and signed by user a.
The user A needs to trade the digital asset and finds a buyer user B, the user A sends asset token information to the user B through online/online, and the user B confirms to buy the asset through the asset token information and approves the pricing in the asset token information or negotiates a transaction price with the user A. A
User B initiates a transaction payment digital currency and submits asset token information to the digital asset transaction system. Optionally, the digital asset transaction system sends an asset transaction confirmation message to the payee user a terminal and optionally requires user a to also submit asset token information. The digital asset transaction system compares the asset token information submitted by user a (which may be submitted) and user B, including verifying that the signatures are valid, comparing the asset digest and information for consistency, etc. And after the verification is passed, submitting the transaction, the digital asset token information and the verification information to a digital currency system.
The digital money system executes a transaction, i.e., discards the digital money (source money) of the user B, generates new digital money (destination money), and hands it to the user a. When generating new digital currency, storing the transaction asset token into the digital currency or storing the transaction asset token into an intelligent contract associated with the digital currency, and realizing the direct binding association between the currency and the assets.
At this point, user A and user B complete a digital asset transaction. The user B can generate a new digital asset token which is represented as a legal asset owner of the new asset, the token of the new asset comprises original token information, the asset value can be traced continuously, and if the token does not comprise the original token information, the fact that the asset value is not source is represented.
Thereafter, user B and user C may conduct subsequent digital asset transactions. During transaction, a new digital asset token signature may be provided for each transaction, or an original digital asset token may be provided for tracing back and re-transaction. Meanwhile, each transaction user can anonymously inquire the data of the asset and currency bidirectional circulation chain, and the tracing of the digital asset is realized. When inquiring, submitting the signature information of the held digital asset token and/or old money paid by the original purchased digital asset, or submitting the information of the asset token obtained from the user B by the current purchaser user C (through an asset transaction platform interface), submitting the information to a digital currency system, appointing to trace the source of the asset from the user B wallet, leading the user C to clearly obtain the historical transaction information of the asset, and then confirming whether to perform transaction, transaction price and the like.
As shown in FIG. 3, in one embodiment, the digital currency system of the present invention includes an acquisition module 31, a verification module 32 and a transaction module 33.
The obtaining module 31 is configured to obtain digital asset token information provided by a digital asset purchase terminal through a digital asset transaction system, where the digital asset token information includes a digital asset token and signature information.
