The withdrawal/deposit is responsible for withdrawing or depositing funds held in custody during the transaction, the rate management is responsible for managing the rate of commissions withdrawn by the re-authorization transaction system, and the query is responsible for querying funds held in custody, rates, and the like.
It should be noted that the trans-authorization transaction system may be connected to a peripheral system, and the peripheral system may include a KYC (Know Your Customer) system, a copyright registration system, a judicial deposit system, a digital currency access system, and the like. The KYC system is responsible for authenticating a person's identity or a public identity based on a digital identity. The copyright registration system is responsible for registering the copyright of creators and works. The digital currency access system is responsible for accessing digital currency.
Referring to fig. 2, a flowchart of a method for re-authorizing a transaction of a digital asset according to an embodiment of the present application is shown, which can be applied to a block chain-based re-authorizing transaction system including the block chain-based re-authorizing transaction system shown in fig. 1.
The digital asset transfer authorization transaction method can comprise the following steps:
A holder may refer to a holder of the original property right, i.e. the original owner, who has the right to register the authorization type; alternatively, the holder may be the owner after purchasing the digital asset through the secondary market.
After the holder registers the digital identity through the digital identity intelligent contract, the holder can provide the digital identity to the transfer authorization transaction system when registering the digital collection, the transfer authorization transaction system can authenticate the digital identity, if the authentication is passed, the subsequent steps are continued, and if the authentication is not passed, the flow is ended.
Alternatively, whether the re-authorization transaction system supports KYC certification may be determined based on local policy and compliance requirements. If KYC authentication is supported, the authorization transfer transaction system can perform KYC authentication on the holder by using the digital identity of the holder; if the KYC authentication passes, continuing to execute the subsequent steps; if the KYC authentication fails, the flow ends.
After the identity authentication is passed, the transfer authorization transaction system can acquire the identity information of the owner, inquire works registered by the owner in the copyright registration system according to the identity information, generate ownership and various transfer authorizations of the digital assets according to the works, and create corresponding relations between the ownership and various transfer authorizations of the digital assets held by the owner and the owner. Or after the identity authentication is passed, the transfer authorization transaction system can acquire the identity information of the holding party and the information of the works, verify whether the holding party is the creator of the works in the copyright registration system according to the identity information and the information of the works, if so, generate ownership and various transfer authorizations of the digital assets according to the works, create corresponding relations between the ownership and various transfer authorizations of the digital assets held by the holding party and the holding party, and if not, end the process.
At least one kind of transfer authorization to be traded by the holding party and the trade setting information of each kind of transfer authorization are obtained, wherein the transfer authorization is the right of the holding party to the digital assets except the ownership right.
The holder may select at least one of the various re-authorizations he holds for the transaction. Specifically, the holder may register at least one type of transfer authorization to be transacted and transaction setting information for each type of transfer authorization in the transfer authorization transaction system. The transaction setting information may include a price of the re-authorization, an authorization deadline, and the like, and the transaction setting information of different re-authorizations may be all the same, may also be all different, and may also be partially the same, which is not limited in this embodiment.
After the re-authorization and transaction setting information of the to-be-transacted is registered, the holding party can modify the information. Specifically, the holding party can send a change request to the transfer authorization transaction system, and the transfer authorization transaction system receives the change request sent by the holding party, wherein the change request comprises transfer authorization and/or transaction setting information which needs to be changed; and updating the re-authorization and/or transaction setting information according to the change request. For example, the re-authorization transaction system adds a re-authorization to be transacted and transaction setting information thereof, or the re-authorization transaction system deletes a re-authorization to be transacted and transaction setting information thereof, or the re-authorization transaction system modifies a re-authorization price to be transacted, or the re-authorization transaction system prolongs an authorization period of the re-authorization to be transacted.
It should be noted that the identity of the owner needs to be verified before the change, and the transfer authorization and/or the transaction setting information needs to be changed after the authentication is passed.
If the holder needs to limit the number of users who transfer the same type of authorization to a plurality of users, the holder needs to register the limit amount of users to be transacted in the authorization transaction system.
And step 203, receiving a re-authorization transaction request sent by the user aiming at the target re-authorization, and instructing the user to pay funds according to the price in the transaction setting information according to the re-authorization transaction request, wherein the target re-authorization is one of at least one type of re-authorization.
The user is a user who obtains a usage authorization from the holder and can use the digital asset within the authorization range.
When the user needs to purchase the transfer authorization of the digital asset, the transfer authorization to be transacted can be inquired in the transfer authorization transaction system. Specifically, the user sends an inquiry request to the re-authorization transaction system, the re-authorization transaction system receives the inquiry request sent by the user, displays at least one kind of re-authorization to be transacted and transaction setting information of each kind of re-authorization to the user according to the inquiry request, and the user can select one kind of re-authorization from the re-authorization request as a target re-authorization and send a re-authorization transaction request aiming at the target re-authorization to the re-authorization transaction system. The re-authorization transaction system may directly instruct the user to pay the funds at the price in the transaction setting information after receiving the re-authorization transaction request, or may instruct the user to pay the funds at the price in the transaction setting information after the owner approves the re-authorization transaction system.
And step 204, after the payment is successful, granting the use authority of the target transfer authorization to the user, and transferring the funds paid by the user into the escrow contract.
A trans-authorization transaction system requires the transfer of funds paid by a user into a escrow contract rather than directly to a holding party.
The funds paid by the user will be escrowed and locked in the escrow contract and the funds brought up will be dynamically unlocked by the user for the authorized length of use. Specifically, the transfer authorization transaction system may calculate a cash-out amount according to a usage duration of the target transfer authorization by the user, and transfer funds corresponding to the cash-out amount to a fund account of the holder from the escrow contract, where the usage duration is counted from a time when the usage permission of the transfer authorization by the user is granted.
When calculating the cash-out amount and the holder firstly promotes, obtaining the authorization time length of the target transfer authorization and the use time length of the user on the target transfer authorization, calculating the ratio of the use time length to the authorization time length, and multiplying the total sum of the funds by the ratio to obtain the cash-out amount; when the holder is not presented for the first time, the authorization duration of the target transfer authorization and the use duration of the target transfer authorization by the user are obtained, the ratio of the use duration to the authorization duration is calculated, the total sum of the fund is multiplied by the ratio, and the sum of the withdrawal is subtracted from the obtained product to obtain the withdrawal amount.
In this embodiment, the manager of the re-authorization transaction platform may extract a commission from the transaction, and the manager may dynamically unlock the commission of the cash-out according to the usage duration of the re-authorization by the user, or the manager may unlock the commission of the cash-out at one time. Specifically, after payment is successful, a cash withdrawal request sent by a manager of the transfer authorization transaction system or an intelligent contract is received; calculating a commission amount according to a preset rate and funds paid by a user; funds corresponding to the commission amount are transferred from the escrow contract to the administrator's funds account.
Wherein the management party can modify the commission as needed. Specifically, the re-authorization transaction system receives a rate change request sent by a manager, wherein the rate change request comprises a changed rate; and updating the rate according to the rate change request. Note that the identity of the administrator needs to be verified before the change, and the rate needs to be changed after the authentication is passed.
In this embodiment, the owner may transfer ownership of the digital asset to a new owner. When ownership of the digital assets is transferred to a new holder by the holder, the transfer authorization transaction system needs to update the holder in the corresponding relationship to the new holder and update the fund account of the holder in the escrow contract to the fund account of the new holder, so that the new holder can present the fund obtained by the transfer authorization of the transaction.
The owner may transfer ownership of the digital asset through a trans-authorization transaction system. At the moment, the transfer authorization transaction system receives an ownership transaction request sent by the holder, indicates the holder to trade ownership of the digital assets with a new holder according to the ownership transaction request, updates the holder in the corresponding relationship to the new holder after the transaction is successful, and updates the holder's fund account in the escrow contract to the new holder's fund account so that the new holder can present the fund obtained by transfer authorization of the transaction target. Alternatively, the first and second electrodes may be,
the owner may transfer ownership of the digital asset through other systems and change ownership after a transaction is successful through a re-authorization transaction system. At this time, the transfer authorization transaction system receives an ownership change request sent by the holder, wherein the ownership change request is sent after the holder transfers ownership of the digital asset to a new holder, the holder in the corresponding relationship is updated to the new holder according to the ownership change request, and the holder's fund account in the escrow contract is updated to the new holder's fund account, so that the new holder can withdraw the fund obtained by the transaction transfer authorization.
After transferring ownership, the new holder may cash out the trans-authorized transaction funds that were hosted in the escrow contract. Specifically, the transfer authorization transaction system may calculate a usage duration of the target transfer authorization by the user after the ownership transfer is successful, calculate a cash-out amount according to the usage duration, and transfer funds corresponding to the cash-out amount to a new holder's fund account from the escrow contract. The calculation method of the prompt amount is described in detail in the above description, and is not described herein again.
In this embodiment, the transfer authorization transaction system may or may not support the emptying operation of the transfer authorization, and whether the emptying operation is supported by the transfer authorization transaction system or not may be implemented by setting in a system configuration item by the administrator or the transfer authorization transaction system.
If the re-authorization transaction system supports a clearing operation of the re-authorization, the new holder may reclaim the already transacted re-authorization after transferring ownership. Specifically, if the authorization transfer transaction system supports an emptying operation of authorization transfer, the authorization transfer transaction system receives an emptying request sent by a new holding party, wherein the emptying request comprises information of target authorization transfer and information of a user; clearing the use authority of the user for transferring the authorization to the target according to the clearing request; and calculating a reimbursement amount according to the use duration of the target transfer authorization of the user, and transferring funds corresponding to the reimbursement amount to a fund account of the user from the escrow contract. For example, when a new holder needs to reclaim the transfer authorization, the usage duration of the user reaches half of the authorization duration, and half of the transaction funds can be returned to the user.
In this embodiment, the third party may query the related information of the digital asset at any time, and the third party is a user of the re-authorization transaction system. For example, the third party may query an authorization record of a certain re-authorization, and may also verify whether a certain user has a certain re-authorized usage right. Specifically, the re-authorization transaction system receives a query request sent by a third party; when the query request comprises the information of the user, querying the transfer authorization granting the use authority to the user, and feeding back an authorization record containing the transfer authorization to the third party; and when the query request comprises the information of the user and the information of the transfer authorization, querying whether the user is granted the use authority of the transfer authorization or not, and feeding back the obtained query result to the third party.
In summary, the digital asset re-authorization transaction method provided in the embodiment of the present application can ensure the authenticity of the identity of the holding party and the compliance, validity and effectiveness of the business authorization for re-authorization of digital assets in a chain by authenticating the digital identity of the holding party.
By independently registering ownership and re-authorization of the digital assets, the re-authorization can be independently circulated, thereby providing the holder with more rights and interests besides selling ownership, and further providing more ways to motivate the holder. In addition, complete authorization chain information can be stored through an intelligent contract on the chain, and the rights and interests of a user are guaranteed through the intelligent contract, so that the influence of ownership change and the like is avoided.
The funds paid by the user are managed and locked in the managed contract, and the withdrawn funds are dynamically unlocked according to the use duration of the trans-authorization by the user, so that the new owner of the ownership can continuously extract the funds paid by the user after the ownership is transferred, and the rights and interests of the new owner and the user can be guaranteed simultaneously.
