The digital asset may further comprise: e-books, network application assets of the usage rights of video or audio, etc. In summary, the digital assets in this embodiment may be: various assets used in the internet are indicated with digital information.
In fig. 1, the central server and the distributed servers are connected in a star topology. In some embodiments, other topological connections between the central server and the distributed servers may also be employed. In this embodiment, the distributed server is also essentially the server of the ownership and/or usage rights transfer process of the digital asset. An information processing method regarding generation of an identification code is provided below in connection with the transaction platform shown in fig. 1.
The digital asset rights in this embodiment may include: ownership, usage rights, revenue and/or change rights, development rights, redemption rights, and the like. The redemption rights may be redeeming other digital assets or physical objects off-line.
The non-personal right of the digital asset in this embodiment is a right that can be transferred, for example, ownership of a game gold coin of a network game, etc., and for example, usage right of the digital asset for reading a certain electronic book or network video, etc.
As shown in fig. 2, the present embodiment provides a method for directional transfer of digital assets, which is applied to a central server, and includes:
step S110: receiving a directional transfer request and directional transfer information of a transfer party user request digital asset, wherein the directional transfer information at least comprises: a transferee user identification code of the transferee user;
step S120: based on the directional transfer request, a first certificate identification code of the digital asset held by the transferor user is sent to a distributed server for verification;
step S130: after the first credential identification code passes verification, freezing the digital asset corresponding to the first credential identification code;
step S140: sending a directional transfer notification to an account where the transferee user identifier is located; the directional transfer notification is used for being displayed on an account interface of the transferee user so as to perform directional transfer of the frozen digital asset when receiving an agreement instruction of the transferee user;
Step S150: when receiving the consent instruction of the transferee user, generating a second certificate identification code by combining the transferee user identification code and the asset identification code of the digital asset;
step S160: the first credential identification code is invalidated.
The directional transfer herein designates the transfer mode of at least a portion of the rights of a digital asset of the transferee user to the transferee user.
In this embodiment, the directional transfer request for the directional transfer is further issued by the user client of the transferor user. The directional transfer information may be received from the user client together with the directional transfer request, or may be received separately. Optionally: the directional transfer request carries the directional transfer information.
Specifically, the user client of the transferor user displays a directional transfer interface, where an input box for the transferor user to fill in various directional transfer information may be displayed, for example, the transferor user may input a user identifier of the transferee user in the directional transfer interface, where the user identifier may be a name, an identifier, or a search field of the transferee user, the transaction platform receives the search field, performs matching of the search field, and then outputs a user identifier of the transferee user that the transferee user wants to find, based on a result of matching the search field, and returns the user client of the transferee user; after receiving the search result, the user client displays the corresponding searched user identification codes as the candidate users of the transferee user in various forms such as a drop-down list.
At this time, the transferor user can input the transferor identification code to the transaction platform according to the fuzzy impression without precisely inputting the user identification code of the transferor user.
In some embodiments, the user client of the transferee user may scan the two-dimensional code of the transferee user by means of two-dimensional code scanning, and submit the scanned two-dimensional code to a transaction platform, and the transaction platform obtains the transferee user identification code through identification of the two-dimensional code.
In still other embodiments, a two-dimensional code identification module is built in a user client connected with the transaction platform, and after the user client of the transferor user scans the two-dimensional code of the transferee user, the scanned two-dimensional code is locally identified to obtain the transferee user identification code, and the transferee user identification code is displayed at the display position of the transferee user identification code of the directional transfer interface, so that the transferee user does not need to manually fill in the transferee user identification code.
After receiving the directional transfer information, the central server determines both sides of the current directional transfer based on the user identification code of the transmitting account transmitting the directional transfer information.
In order to ensure illegal transfer in the process of directional transfer, the certification of the corresponding certification identification code (namely the first certification identification code) of the digital asset is performed, and only if the first certification identification code is legal, the legitimacy of the digital asset can be ensured. In the embodiment, the legal first certificate identification codes are stored in the whole transaction platform in a distributed mode, and the distributed storage can increase the difficulty of falsifying the certificate identification codes and improve the safety of digital assets.
Before the directional transfer is carried out in the application, the first certificate identification code is sent to the distributed server, the distributed server verifies based on a consensus mechanism, and only after the number of enough distributed servers passes the verification or after more than half of distributed servers pass the verification of the first certificate identification code, the first certificate identification code is considered to be valid, and the digital asset corresponding to the first certificate identification code is considered to be really in the transaction platform.
Freezing the digital asset corresponding to the first credential identification code after the first credential identification code passes verification in step S130; specifically, a state field corresponding to the first certificate identification code is set, and specific content of the state field is set to be in a frozen state. When the status field of the first credential identification code is set to a frozen state, the digital asset corresponding to the first credential identification code is frozen and is not allowed to be transferred in a manner other than the directional transfer corresponding to the directional transfer request.
In some embodiments, after the central server receives the directional transfer request, setting a directional transfer identification code; and when the digital asset corresponding to the first credential identification code is frozen, storing the orientation transfer identification corresponding to the first credential identification code. And if the directional transfer identification codes corresponding to the first certificate identification codes are not consistent through comparison of the transfer identification codes when other transfer is carried out later, rejecting the corresponding transfer.
After verification and freezing are completed, a directional transfer notification is sent to the account where the transferee user identification code is located in step S140. Here, the directional transfer notification prompts the transferee user that the transferee user sent a directional transfer invitation to him. The invitation may carry information such as a user identification code of the transferor user. In some embodiments, the invitation also carries information such as asset types and asset numbers of the corresponding digital assets, so that the user is convenient for the transferee user to check.
In step S150, if the central server of the transaction platform receives the consent instruction of the transferee user, the transferee user identifier and the asset identifier of the digital asset are combined to generate a second certificate identifier by mixing through a preset algorithm after the consent instruction of the transferee user is informed about the direction; the binding of the digital asset and the transferee user is realized through the mixing of the transferee user identification code and the asset identification code through the second certificate identification code.
To avoid one digital asset being held by multiple users at the same time while the second credential identification code is validated, the central server may invalidate the first credential identification code.
Invalidation of the first credential identification code, comprising: and setting an identification status field of the first credential identification code to be invalid or directly deleting the first credential identification code.
Invalidating the first credential identification code of step S160 in this embodiment may include:
the central server deletes the locally stored first credential identification code;
broadcasting a deleting instruction to the distributed server;
and after the distributed server receives the deleting instruction, deleting the first credential identification code stored in the distributed server. In summary, the deletion instruction is configured to trigger the distributed server to delete the first credential identifier stored in the distributed server.
In some embodiments, upon invalidating the first credential identification code, validating the second credential identification code, the method may include:
broadcasting replacement instructions to all distributed servers in the transaction platform; the replacement instruction carries a first credential identification code which needs to be invalid and a second credential identification code which needs to be valid.
After receiving the replacement instruction, the distributed server invalidates the first credential identification code, and simultaneously validates the second credential identification code, so that the time difference for invalidating the first credential identification code and validating the second credential identification code is reduced as much as possible, and two credential identification codes of the right of one digital asset corresponding to the same type of digital asset are reduced.
The method in the embodiment provides a method for facilitating automatic selection of both transfer parties, and transfer is carried out on a transaction platform instead of off-line private transfer, and the credential identification code is generated through combination of the user identification code and the asset identification code, so that the holding switching of different users on the digital asset is realized through generation of the credential identification code, and the transfer security of the digital asset is ensured.
Optionally, as shown in fig. 3, the method further includes:
step S101: analyzing the first credential identification code to extract an asset identification code of the digital asset and a binding user identification code of the digital asset binding;
step S102: comparing the binding user identification code with a transferor user identification code of the transferor user;
step S103: based on the asset identification code, a determination is made as to whether the digital asset is in a transferable state.
The step S130 may include a step S131; the step S131 may include: and freezing the digital asset corresponding to the first credential identification code when the binding user identification code is consistent with the transferor user identification code and the digital asset is in a transferable state.
Before the corresponding digital asset is frozen in this embodiment, the first credential identifier code needs to be parsed to obtain the user identifier code and the asset identifier code that are generated by mixing, and the user identifier code extracted from the first credential identifier code is the binding user identifier code.
And comparing the binding user identification code of the first credential identification code with the identifier of the transferor requesting the directional transfer. If the two identification codes are matched, the transferee user requesting the directional transfer is considered to have the transfer right of at least part of the rights of the digital asset corresponding to the first certificate identification code; thereby completing the right confirmation before the directional transaction.
In some embodiments it may also be desirable to verify that the current status of the transferor user allows transfer of the digital asset. For example, the account of the transferor user is not frozen, no transfer is permitted, and so on.
Verification is also based on the asset identification code of the digital asset in this embodiment. In some cases, the digital asset purchased on the same day may be prohibited from being transferred, so it is desirable in this embodiment to determine that the corresponding digital asset is transferable.
Therefore, in step S130 of the present embodiment, if it is determined that the binding user identifier is consistent with the transferor user identifier, and the digital asset pointed to by the transfer request is transferable, the corresponding digital asset is frozen. This can reduce the subsequent unnecessary operations.
Optionally, the directional transfer information further includes: at least one of a transfer type, a transfer unit price, a transfer total price, a transfer number, and a transfer time limit;
the transfer category is a type of the digital asset for which transfer is requested;
the transfer unit price is a transfer price for a share of the digital asset;
the total transfer price is the total price of the digital resource transferred at this time;
the transfer time limit includes: the latest transfer time and the transfer time corresponding to the plurality of transfers.
There are a variety of digital assets in the trading platform, and a user may also hold a variety of digital assets.
In this embodiment, the user client of the transferor user submits type information to the transaction system indicating the type of digital asset specified to be transferred.
In some cases, the maximum number of one-time transfers is limited, e.g., related to the level of the transferor user; generally, the higher the level of the transferor user, the greater the maximum number of one-time transferables. In the present embodiment, therefore, if the number of transfers is large, it is impossible to complete the number of directional transfers at a time. The transferor user may also specify the number of transfers. And the central server of the trading platform receives the transfer quantity and the transfer times and determines the transfer quantity of each time. For example, the transfer amount of each time is determined by division operation, and when the transfer amount cannot be divided, the trigger remainder amount is dispersed to the partial transfer times, so long as the maximum amount is not ensured to be exceeded.
Optionally, the method further comprises:
transmitting the second certificate identification code to a distributed server for verification;
the step S160 may include:
and when the second certificate identification code is validated after passing the verification, invalidating the first certificate identification code.
In this embodiment, the second credential identification code needs to be verified, and only after verification is passed and validated, the first credential identification code is invalidated. When the second certificate identification codes are effective, the second certificate identification codes are stored in the central server and each distributed server in a distributed mode, so that one second certificate identification code can be kept in a plurality of servers, and at least a plurality of copies need to be tampered if illegal users need to tamper, so that the successful tampering can be ensured, and the security of the certificate identification codes is improved.
Optionally, the directional transfer information further includes: transfer number;
the method further comprises the steps of:
querying an account of the transferee user to determine whether the number of holds of the digital asset held by the transferee user is greater than the transfer number;
the step S120 may include:
and when the holding quantity is not smaller than the transfer quantity, sending the first certificate identification code which is equal to the transfer quantity to a distributed server for verification.
In this embodiment, if the transferor user specifies the transfer number, it needs to be ensured that the transfer number is not requested to exceed the amount held by the transferor user, so in this embodiment, the method further includes: comparing the holding quantity of the transferor users with the transfer quantity, if the holding quantity is not less than the transfer quantity, the subsequent operation can be performed, otherwise, an abnormal prompt is output to prompt the transferor users to transfer the transfer quantity downwards, and when the prompt is performed, the maximum quantity of transferor users which can be transferred is output, so that the transferor users can conveniently check.
Optionally, the method further comprises:
and outputting a directional transfer abnormality prompt to the account of the transferee user when the holding quantity is smaller than the transfer quantity.
In some embodiments, the transfer number may be defaulted in the directional transfer information. And the number of transfers may be determined by the transferee upon consent to receive the directional transfer.
In some embodiments, the consent instruction may further comprise: the number of assigned agreements to accept the transfer; the number of assigned users determined by the transferee user in this embodiment cannot be greater than the number of transferors of the transferor user or the number of holds or transfers of the transferor user.
In some embodiments, the method further comprises:
when the transferee user agrees to the transferee, outputting a first prompt to an account of the transferee user, wherein the first prompt is used for prompting the transferee user to accept the directional transfer;
and/or the number of the groups of groups,
and when the directional transfer is successful, outputting a second prompt to the transferor user and the transferee user respectively, wherein the second prompt is used for directional transfer.
In this embodiment, the verification of the first credential identification code and the second credential identification code may include: the first certificate identification code and the second certificate identification code are synchronously transmitted to the distributed server for verification; the distributed server can vote and verify the first credential identification code and the second credential identification code based on a consensus mechanism; only when more than half of the distributed servers are selected to consider that the first certificate identification code and the second certificate identification code pass verification, the first certificate identification code and the second certificate identification code pass verification. The first credential identification code may be directionally transferred through authentication, and only the second credential identification code may be validated if the second credential identification code is authenticated. On the one hand, the central server generates the new certificate identification code, so that the uniqueness of the generated new certificate identification code is ensured, and the distributed verification of the distributed server can ensure the reliability of the generated certificate identification code.
