There is a need for a simple and effective asset transfer method that is not complex, but also allows for asset security, and that maximizes the user's asset security even when the exchange runs. Based on the above, the method, the device and the server for transferring the digital asset, provided by the embodiment of the invention, can be applied to any digital asset transfer service; the absolute control right of the exchange to the digital asset can be reduced in the transfer process of the digital asset, so that the digital asset safety of the user is ensured.
The present invention is not limited to conventional blockchain virtual currency transactions, but is equally applicable to digital currency extension services such as blockchain integration, and the like.
For ease of understanding the present embodiment, a method for transferring digital assets disclosed in the present embodiment will be described in detail.
Embodiment one:
firstly, the embodiment of the invention provides a transfer method of digital assets, wherein a user of the digital assets is preset with a plurality of multi-sign addresses; assets in the multi-signature address are transferred after being signed by the multiparty private key; the multi-party private key comprises private keys of at least two parties in the user, the exchange and the third party credit facility; as shown in fig. 1, the method is executed by a transaction center, and specifically comprises the following steps:
step S102, receiving a digital asset transfer request from a first user and a first digital asset from a first preset digital asset address of the first user; wherein the digital asset transfer request includes a second digital asset to be transferred and a second user to whom the second digital asset belongs;
the exchange can provide different digital asset exchange services, and can provide a mechanism of the block chain encryption digital currency exchange service, and the mechanism has the functions of user authentication, matching transaction, hosting, multi-sign and the like; the third party credit mechanism is independent of the exchange and the user, is a fair third party mechanism and mainly provides services such as user authentication, multi-sign and the like; the multi-sign address may be an address commonly generated by a transaction center, a third-party credit institution, and a public key of the user; the first user may look up the types and the amounts of the digital assets that the different users want to transfer out and the types and the amounts of the digital assets that want to exchange according to the to-be-exchanged list provided by the exchange, and then select the user to actively transfer the assets according to the types and the amounts of the money owned by the user. The preset digital asset address may be used to store a corresponding digital asset, and each user may have a plurality of digital asset addresses, each of which may store a digital asset. The second digital asset to be transferred may be a digital asset to be sold in a to-be-exchanged list provided by the exchange, and the second user may be a user to whom the digital asset to be sold belongs in the to-be-exchanged list provided by the exchange.
Specifically, the first user may view the list to be exchanged provided by the exchange, and determine whether he wants to transfer according to the type and number of digital assets provided in the list and the type and number of digital assets that can be exchanged with the type of digital assets, and if so, determine transfer information of the transfer, including: the digital asset to be transferred, namely the second digital asset, the digital asset to be transferred, namely the first digital asset and the second user to whom the digital asset to be transferred belongs, are simultaneously used for establishing a digital asset transfer request by using the determined transfer information, so that the exchange transfers the first digital asset of the first user according to the second user and the second digital asset included in the digital asset transfer request.
Step S104, transferring the first digital asset to a first multi-sign address of a first user, and forwarding the digital asset request to a second user;
the first multi-sign address may be generated by public keys of the first user, the exchange, and the third party credit facility for storing the transferred first digital asset for common control of the asset by the third party; when a user selects to generate a multi-sign address, a plurality of third-party credit mechanisms and a plurality of exchanges can be added according to specific needs of the user in an actual scene, the user can select proper credit mechanisms and exchanges according to credit scores of the exchanges and the credit mechanisms, and the user can select proper third-party credit mechanisms and exchanges according to credit scores of the exchanges and the credit mechanisms, so that risks are dispersed; the above-mentioned forwarding of the digital asset request to the second user allows the second user to receive the asset transaction intended by himself, with whom the user is already ready to make this asset transaction, while the second user can learn that the user who is ready to make the transaction is the first user, based on the digital asset request.
Specifically, the exchange checks based on the type and quantity of the first digital asset received, transfers the first digital asset to the first multi-sign address of the first user if it matches the type and quantity of the mutually redeemed digital asset included in the digital asset transfer request, and then forwards the digital asset request to the second user.
Step S106, transferring the first digital asset to a second multi-sign address of a second user through private keys of at least two parties in the first user, the exchange and the third party credit organization; and transferring the second digital asset of the third multi-sign address of the second user to the fourth multi-sign address of the first user through private keys of at least two parties in the second user, the exchange and the third party credit facility.
After the first user transfers the first digital asset to the first multi-sign address through the exchange, indicating that the exchange has determined the users transferring the assets to each other; at this time, the first digital asset is transferred to a second multi-sign address of the second user, typically after being signed together by both private keys of the first user and the exchange; if the exchange cannot provide normal functions, such as network failure of the exchange, switching of the exchange, and the like, the first user can complain to the third-party credit organization independently, and the first digital asset is transferred to a second multi-sign address of the second user through the two private keys of the first user and the third-party credit organization together; or if the private key of the first user is lost, that is, the user cannot provide the private key for signing, the user cannot verify the identity of the user to the exchange and the third-party credit organization through the private key, in this case, the user can perform real-name authentication or other authentication modes such as short message authentication mobile phone number and the like to prove the ownership of the user to the multi-sign address when logging in the exchange account. And meanwhile, the third-party credit mechanism and the exchange can verify the real-name authentication of the user, and if the third-party credit mechanism and the exchange verify the real-name authentication of the user, the first digital asset can be transferred to a second multi-sign address of a second user through the common multi-sign of the private keys of the two parties of the third-party credit mechanism and the exchange.
Transferring the first digital asset to a second multi-sign address of a second user, and simultaneously, after the second user and a private key of two parties of a transaction center are signed together, transferring a second digital asset of a third multi-sign address of the second user to a fourth multi-sign address of the first user; if the exchange cannot provide normal functions, such as network failure of the exchange, switching of the exchange, and the like, the second user can complain to the third-party credit mechanism independently, and transfer the second digital asset of the third multi-sign address of the second user to the fourth multi-sign address of the first user through the common multi-sign of the two private keys of the second user and the third-party credit mechanism; or if the private key of the second user is lost, complaining can be carried out to the exchange and the third-party credit mechanism, the authenticity of the user identity is applied, and after the third-party credit mechanism and the exchange jointly confirm that the user application is true, the second digital asset of the third multi-sign address of the second user can be transferred to the fourth multi-sign address of the first user through the common multi-sign of the private keys of the two parties of the third-party credit mechanism and the exchange.
The embodiment of the invention provides a digital asset transfer method, which is used for receiving a digital asset transfer request from a first user and a first digital asset from a first preset digital asset address of the first user; transferring the first digital asset to a multi-sign address of the first user, and forwarding the digital asset request to the second user; the first digital asset is transferred to the multi-sign address of the first user and the second digital asset is transferred to the multi-sign address of the first user by private keys of at least two of the first user or the second user, the exchange and the third party credit facility. In the mode, in the transfer process of the digital asset, a plurality of multi-signature addresses are set, so that the assets in the multi-signature addresses can be transferred only by multi-party private key signature in the asset transfer process, the absolute control right of the exchange on the digital asset is reduced, and the digital asset safety of a user is further ensured.
Further, referring to another digital asset transfer method shown in fig. 2, a specific implementation procedure of a step before receiving a digital asset transfer request from a first user (implemented through steps S202-S206) and a specific implementation procedure of a step after transferring the first digital asset to a first multi-sign address of the first user (implemented through step S212) are described with emphasis, and as shown in fig. 2, the method includes the steps of:
step S202, receiving a digital asset exchange application from a second user and a second digital asset from a third preset digital asset address of the second user; wherein the digital asset redemption application includes a first digital asset to be redeemed;
typically, the exchange determines whether the user has a transaction requirement by receiving a digital asset redemption application from the user, while receiving a second digital asset that the user would like to transfer out; typically the digital asset redemption application includes a first digital asset that the user wants to transfer through a second digital asset. The first user can set the type of the digital assets which are wanted to be exchanged according to the actual demands, the type can be one type or multiple types, and then the amount of the exchanged currencies is determined by converting according to the real-time currency price.
Step S204, transferring the second digital asset to a third multi-sign address of the second user;
the multi-sign address may be generated by public keys of the second user, the exchange, and the third party credit facility for storing the transferred second digital asset for common control of the asset by the third party; after the exchange receives the digital asset exchange application sent by the second user and the second digital asset, firstly transferring the received second digital asset to a third multi-sign address of the second user.
Step S206, generating information to be converted according to the digital asset conversion application and the second digital asset;
the information to be redeemed is typically found by querying a list of transactions to be sold at a trade exchange, including the type and quantity of digital assets the user wants to sell, and the type and quantity of digital assets the user wants to redeem. Specifically, after the exchange transfers the second digital asset to the third multi-sign address of the second user, the exchange information can be generated according to the digital asset exchange application and the second digital asset, and the exchange information is uploaded to a to-be-sold transaction list provided by the exchange, so that other users can select the number of types of digital assets to be exchanged according to the exchange information in the list.
Step S208, receiving a digital asset transfer request from a first user and a first digital asset from a first preset digital asset address of the first user; wherein the digital asset transfer request includes a second digital asset to be transferred and a second user to whom the second digital asset belongs;
step S210, transferring the first digital asset to a first multi-sign address of a first user, and forwarding a digital asset transfer request to a second user;
step S212, deleting the information to be exchanged;
when the first digital asset of the first preset digital asset address of the first user is transferred to the first multi-sign address, the transaction is locked, and in order to avoid the repeated transaction of other users, the information to be exchanged is deleted from the to-be-sold list of the exchange, and other users cannot enter the transaction continuously.
Step S214, transferring the first digital asset to a second multi-sign address of a second user through private keys of at least two parties in the first user, the exchange and the third party credit organization; and transferring the second digital asset of the third multi-sign address of the second user to the fourth multi-sign address of the first user through private keys of at least two parties in the second user, the exchange and the third party credit facility.
Further, after transferring the first digital asset to the first multi-sign address of the first user, the method further comprises: if a digital asset transfer termination request is received from the first user and/or the second user, transferring the first digital asset to a first preset digital asset address or a designated account address of the first user and/or transferring the second digital asset to a third preset digital asset address or a designated account address of the second user by a private key of a third party credit facility and a transaction office.
Specifically, during the preparation of the transaction, during a predetermined period of time, for example, two days, five days, or seven days after transferring the first digital asset to the first multi-sign address of the first user, typically no longer than seven days, if the first user wants to terminate the transaction, the third party credit facility and the exchange may be applied for coordination arbitration, after the third party credit facility and the exchange agree, the first digital asset may be transferred to the first predetermined digital asset address of the first user through private keys of the third party credit facility and the exchange, or the first digital asset may be transferred to the account designated by the first user according to the requirement of the first user.
If the second user wants to terminate the transaction, the second user can apply for coordination arbitration to the third-party credit mechanism and the exchange, and after the third-party credit mechanism and the exchange agree, the second digital asset can be transferred to a third preset digital asset address of the second user through private keys of the third-party credit mechanism and the exchange, or the second digital asset can be transferred to an account appointed by the second user according to the requirement of the second user.
If the first user and the second user want to terminate the transaction, the coordination arbitration can be applied to the third-party credit mechanism and the exchange, after the third-party credit mechanism and the exchange agree, the first digital asset can be transferred to a first preset digital asset address of the first user through private keys of the third-party credit mechanism and the exchange, or the first digital asset can be transferred to an account appointed by the first user according to the requirement of the first user; and transferring the second digital asset to a third preset digital asset address of the second user at the same time, or transferring the second digital asset to an account appointed by the second user according to the requirement of the second user.
Further, referring to another method for transferring digital assets shown in fig. 3, a specific implementation procedure of a step (implemented by step S316) after transferring a second digital asset of a third multi-sign address of a second user to a fourth multi-sign address of a first user is described with emphasis, and as shown in fig. 3, the method includes the following steps:
step S302, receiving a digital asset exchange application from a second user and a second digital asset from a third preset digital asset address of the second user; wherein the digital asset redemption application includes a first digital asset to be redeemed;
step S304, transferring the second digital asset to a third multi-sign address of the second user;
step S306, generating information to be converted according to the digital asset conversion application and the second digital asset;
step S308, receiving a digital asset transfer request from a first user and a first digital asset from a first preset digital asset address of the first user; wherein the digital asset transfer request includes a second digital asset to be transferred and a second user to whom the second digital asset belongs;
step S310, transferring the first digital asset to a first multi-sign address of a first user, and forwarding a digital asset transfer request to a second user;
Step S312, deleting the information to be exchanged;
step S314, transferring the first digital asset to a second multi-sign address of a second user through private keys of at least two parties in the first user, the exchange and the third party credit organization; transferring a second digital asset of a third multi-sign address of the second user to a fourth multi-sign address of the first user through private keys of at least two parties in the second user, the exchange and the third party credit facility;
step S316, transferring the second digital asset to a fourth preset digital asset address of the first user through private keys of at least two parties in the first user, the exchange and the third party credit facility; transferring the first digital asset to a second preset digital asset address of the second user by private keys of at least two of the second user, the exchange and the third party credit facility.
After the first digital asset is transferred to the second multi-sign address of the second user and the second digital asset is transferred to the fourth multi-sign address of the first user, indicating that the asset transaction is completed; after the transfer is successful, the digital assets with the multi-signature addresses need to be transferred to other digital asset addresses of the user; at this time, the second digital asset is transferred to a fourth preset digital asset address of the first user, typically after being signed together by the first user and the two-party private key of the exchange; if the exchange cannot provide normal functions, such as network failure of the exchange, switching of the exchange, and the like, the first user can complain to the third-party credit organization independently, and the second digital asset is transferred to a fourth multi-sign address of the first user through the common multi-sign of the two private keys of the first user and the third-party credit organization; or if the private key of the first user is lost, complaining can be carried out to the exchange and the third-party credit mechanism, the authenticity of the user identity is applied, and after the third-party credit mechanism and the exchange jointly confirm that the user application is true, the second digital asset can be transferred to a fourth multi-sign address of the first user through the common multi-sign of the private keys of the third-party credit mechanism and the exchange.
Meanwhile, after the second user and the private keys of the exchange are signed together, the first digital asset is transferred to a second preset digital asset address of the second user; if the exchange cannot provide normal functions, such as network failure of the exchange, switching of the exchange, and the like, the second user can complain to the third-party credit organization independently, and the first digital asset is transferred to a second preset digital asset address of the second user through the common multi-sign of two private keys of the second user and the third-party credit organization; or if the private key of the second user is lost, complaining can be carried out to the exchange and the third-party credit mechanism, the authenticity of the user identity is applied, and after the third-party credit mechanism and the exchange jointly confirm that the user application is true, the first digital asset can be transferred to a second preset digital asset address of the second user through multiple signatures jointly carried out by the private keys of the third-party credit mechanism and the exchange.
Further, after transferring the second digital asset of the third multi-sign-on address of the second user to the fourth multi-sign-on address of the first user, the method further comprises: if a digital asset termination transfer request of the first user and/or the second user is received, transferring the first digital asset to a first preset digital asset address or a designated account address of the first user and/or transferring the second digital asset to a third preset digital asset address or a designated account address of the second user through a private key of a third party credit mechanism and a transaction center.
Specifically, during the period of the transaction, during a preset time, for example, two days, five days or seven days after transferring the second digital asset of the third multi-sign address of the second user to the fourth multi-sign address of the first user, usually no more than seven days, if the first user wants to terminate the transaction, the first user may apply for coordination arbitration to the third party credit facility and the exchange, and after the third party credit facility and the exchange agree, the first digital asset may be transferred to the first preset digital asset address of the first user through private keys of the third party credit facility and the exchange, or may also be transferred to the account designated by the first user according to the requirement of the first user.
If the second user wants to terminate the transaction, the second user can apply for coordination arbitration to the third-party credit mechanism and the exchange, and after the third-party credit mechanism and the exchange agree, the second digital asset can be transferred to a third preset digital asset address of the second user through private keys of the third-party credit mechanism and the exchange, or the second digital asset can be transferred to an account appointed by the second user according to the requirement of the second user.
If the first user and the second user want to terminate the transaction, the coordination arbitration can be applied to the third-party credit mechanism and the exchange, after the third-party credit mechanism and the exchange agree, the first digital asset can be transferred to a first preset digital asset address of the first user through private keys of the third-party credit mechanism and the exchange, or the first digital asset can be transferred to an account appointed by the first user according to the requirement of the first user; and transferring the second digital asset to a third preset digital asset address of the second user at the same time, or transferring the second digital asset to an account appointed by the second user according to the requirement of the second user.
In the mode, the common transaction address is replaced by the multi-signature address, and the third-party credit mechanism is introduced, so that the control right of the exchange to the digital assets of the user is weakened, the assets stored in the multi-signature account by the user can be ensured to be still safe when the exchange is closed or hacked, the digital assets used for the transaction by the user are stored in the multi-signature account, any single party cannot independently acquire the assets in the multi-signature account, and the digital assets in the multi-signature account can be transacted only by the approval of the appointed number of members which participate in the multi-signature. Under the extreme conditions of exchange switching, hacking and the like, the user asset safety can be ensured to the maximum extent. In addition, when the private key of the user is lost, the user can also find back in a multi-sign mode. When a dispute occurs in a transaction, the third-party credit facility can act as a mediator and referee, and the co-exchange transfers digital currency to the account of the party or returns the digital currency in the original way to terminate the transaction.
Further, referring to a schematic diagram of a to-be-redeemed list shown in fig. 4 and a flowchart of another method for transferring digital assets shown in fig. 5, this embodiment provides a specific implementation manner. Wherein, the user 1 corresponds to the second user; user 2 corresponds to the first user described above; address B1 corresponds to a third preset digital asset address of the second user; the multi-sign address M corresponds to a third multi-sign address of the second user; the multi-sign address N corresponds to a fourth multi-sign address of the first user; address B2 corresponds to a fourth preset digital asset address of the first user; the address E2 corresponds to a first preset digital asset address of the first user; the multi-sign address P corresponds to a first multi-sign address of the first user; the multi-sign address O corresponds to a second multi-sign address of the second user; the address E1 corresponds to a second preset digital asset address of the second user; the currency E corresponds to the first digital asset; currency B corresponds to the second digital asset described above.
Specifically, the user 1 needs to pay a certain amount of charges at the exchange, and the charges include the charges of operations such as user asset transfer charges and user refunds. The user 1 registers an exchange account, and generates multi-signature addresses corresponding to each platform with the exchange and a third-party credit mechanism, as shown in a structural schematic diagram of generating multi-signature addresses in fig. 6, wherein a dotted line indicates that digital assets in the multi-signature addresses can be transferred by multi-party signature. The user 2 registers the exchange account and generates a multi-sign address corresponding to each platform with the exchange and the third-party credit organization.
Firstly, a user 1 transfers 10B coins in an address B1 to a multi-signature address M through a trade station, meanwhile, the accepted exchange currency is sent to the trade station, the trade station is formally in a trade state at the moment, the trade station generates information to be exchanged according to the received information of the user 1, the information is sent to a list to be exchanged, as shown in fig. 4, in the exchange list of the trade station, other users can see the information of the B coins to be sold by the user 1, wherein the information comprises the number of the trade, the exchanged currency, the real-time price of the exchange of the B coins and the E coins; if the user 2 sees the first information in the list to be exchanged, deciding to transfer the asset, converting 200E coins to be paid according to the real-time price and the stable coins, and converting the 200E coins in the address E2 into a multi-label address P through a exchange, wherein the E coins correspond to an arrow 1 in the figure; in the process, the exchange firstly checks whether the quantity of the received E coins is matched with the quantity of the E coins corresponding to the list to be exchanged, if so, 200E coins in the address E2 are transferred to the multi-label address P, the preparation work of the transaction is completed, meanwhile, the information of the first row in the list to be exchanged is deleted, the transaction is locked, and other people cannot enter the transaction continuously. At this time, after the user 2 and the exchange sign more together, the E coin in the multi-sign address P is transferred out to the multi-sign address O, and the E coin corresponds to an arrow 3 in the figure; after the user 1 and the exchange sign more together, the B coin in the multi-sign address M is transferred out to the multi-sign address N, and the arrow 4 in the figure is corresponded. In this process, any party of the user 1 and the user 2 want to terminate the transaction, and can apply for coordination arbitration to the third-party credit mechanism and the exchange, and forcedly withdraw or forcedly roll out the assets in the multi-signature accounts to the designated accounts. The E coins in the multi-signature address O can be transferred out to the designated account address E1 by the signature of the user 1 and the signature of the exchange in the multi-signature address of the B coins and the E coins after the transaction, and the E coins correspond to an arrow 5 in the figure; the B coin in the multi-signature address N can be transferred to the appointed account address B2 by the signature of the user 2 and the signature of the exchange, and the arrow 6 in the diagram is corresponding.
In the whole transaction flow, if the exchange cannot provide normal functions, the exchange can singly complain to a third-party credit organization, and the user and the third-party credit organization jointly pick up a plurality of digital assets in a plurality of addresses, so that the risk is reduced. In addition, if the private key of the user is lost, the digital assets stored in the multi-signature accounts by the user are still safe, the digital assets can be told back to the exchange and the third-party credit organization, and after the third-party credit organization and the exchange confirm that the user application is true, the digital assets can be jointly and multi-signature transferred out to the user designated accounts.
