All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The blockchain technology is widely applied to the fields of electronic commerce, securities trading, internet of things and the like, and provides convenience for activities of users in payment clearing, financial trading and the like by means of the characteristics of decentralization, no tampering, traceability and the like. Meanwhile, the blockchain network can also realize the bulk transfer of assets.

At present, the asset batch transfer is carried out on a block chain platform, a mode of circularly initiating transfer requests by an application layer is mainly adopted, and when the number of the requests is too large, the cost of handling fees of users can be increased, so that the cost of the block chain is increased. Similarly, the operation performance of the blockchain has strong limitation, and the frequent initiation of the transfer request at the application layer can block the blockchain from arriving at the same time, thereby causing the problem of slow transfer confirmation.

In order to solve the above problems, the inventor proposes an asset transfer method, an asset transfer device, an electronic device, and a storage medium in the embodiments of the present application, and calls an intelligent contract when state information of an asset to be transferred satisfies preset state information, so that the intelligent contract transfers the asset to be transferred, thereby implementing batch transfer of the asset and saving block chain overhead.

In order to better understand the asset transfer method, device, electronic device, and storage medium provided in the embodiments of the present application, an application environment suitable for the embodiments of the present application will be described below.

Referring to fig. 1, fig. 1 is a schematic diagram illustrating an application environment suitable for the embodiment of the present application. The asset transfer method provided by the embodiment of the application can be applied to the asset transfer system 10 shown in fig. 1. As shown in fig. 1, the asset transfer system 10 includes electronic equipment and a blockchain service node 130.

The electronic device includes a transmitting end 110 and a receiving end 120. The sending end 110 and the receiving end 120 are named relatively only in one transaction process, and it can be understood that the sending end of the previous transaction in different transactions can also be used as the receiving end of the current transaction, and the receiving end of the previous transaction can also be used as the sending end of the current transaction. Specifically, taking a transfer transaction as an example for explanation, the electronic device that initiates the transaction request to transfer the amount may be denoted as the sending end 110, and the electronic device that receives the transferred amount may be denoted as the receiving end 120. Correspondingly, the user using the sender 110 is denoted as a sender user, and the user using the receiver 120 is denoted as a receiver user. In the embodiment of the present application, the number of the receiving ends 120 may be multiple. The sender 110 is communicatively coupled to the blockchain service node 130, and the receiver 120 is communicatively coupled to the blockchain service node 130 and the sender 110, respectively. Wherein, the intelligent contracts are deployed on the block chain network.

It should be noted that transactions conducted using blockchain techniques may include any type of electronic transaction, including transfers of digital currency (e.g., virtual amounts of bitcoin, legal currency, etc.) as well as other electronic transactions where there is a source address and a destination address, such as transfers of data. In other words, the asset transfer method, apparatus, electronic device, and storage medium provided by the embodiments of the present application may be applicable to various types of electronic transactions using a blockchain, and the asset transfer system 10 may be applicable to various types of electronic transactions, and is not limited to transactions of digital money. The following description will be made by taking the example of the transfer of digital money for convenience of description only.

In the asset transfer system 10, a sending end user may need to send a certain amount of digital currency or other digital, transferable data or digital assets to a receiving end user via a blockchain. The blockchain may be associated with a blockchain network, which may include a plurality of different blockchain service nodes 130, each blockchain service node 130 configured to receive a new transaction request, generate a blockchain, add a blockchain to the blockchain, and broadcast to the blockchain network, and may also authenticate a blockchain, and after a blockchain based on the transaction request is authenticated, the transaction corresponding to the transaction request is completed.

In one example, to perform an electronic transaction via a blockchain associated with a blockchain network, a sender user may initiate a transaction request using an electronic device (in this embodiment, the sender 110) associated with the sender user, where the transaction request is used to transfer a specified amount from a sending address of the sender 110 to a destination address, send a transaction record including the sending address, the destination address, and a transfer amount to the blockchain node 130, package the transaction record into blocks via the blockchain node 130, add a blockchain, broadcast to the blockchain network, and verify the transaction record via other blockchain nodes 130, and then complete a transaction corresponding to the transaction request, that is, transfer the specified amount from the sending address of the sender 110 to the destination address.

In some embodiments, the sender 110 may be a blockchain node in a blockchain network. In other embodiments, both the sender 110 and the receiver 120 may be a blockchain node in a blockchain network.

The above application environments are only examples for facilitating understanding, and it is to be understood that the embodiments of the present application are not limited to the above application environments.

The asset transfer method, device, electronic device and storage medium provided by the embodiments of the present application will be described in detail through specific embodiments.

Referring to fig. 2, fig. 2 is a timing diagram illustrating an asset transfer method according to an embodiment of the present application. The asset transfer method provided by the embodiment can be applied to the asset transfer system. The flow shown in fig. 2 will be described in detail below. The above-described asset transfer method may specifically comprise the steps of:

step S110: the sending terminal receives an asset transfer request, and the asset transfer request comprises asset information to be transferred.

In an embodiment of the present application, a sender may receive an asset transfer request. In some embodiments, a user at a sending end may operate in an interface of the sending end to input asset information to be transferred, and the sending end may generate an asset transfer request according to the asset information to be transferred input by the user. The asset information to be transferred may include asset information to be transferred, and the asset information to be transferred may include the amount of assets to be transferred, the number of transfers, the transfer mode, the type of assets to be transferred, social information, and the like. In some embodiments, the transfer number may refer to the number of assets to be transferred that the amount may be split. The transfer mode may include, for example, a uniform transfer or a random transfer, wherein the uniform transfer may mean that the amount of the asset received by each receiving end user is the same, and the random transfer may mean that the amount of the asset received by each receiving end user is randomly determined according to a predetermined rule. The social information may include message information of the sending-end user, and the message information may be used to provide some additional text messages to the receiving-end user, which is not limited herein.

In some embodiments, the assets to be transferred may be in digital currency. The type of the assets to be transferred may be a currency of digital currency, may be a native currency on a blockchain network, or may be a contract currency supported by the blockchain network, and may be at least one of an ethernet currency (ETH), a Bitcoin (BTC), a Bitcoin Cash (BCH), a leite currency (LTC), and a CoinEx token (CET), for example, but not limited thereto.

In one example, the asset transfer request may be a request for mass texting of a red packet, the amount of the asset to be transferred may be a total amount of the red packet, the transfer number may refer to the number of total amount splits of the red packet, i.e., the number of the red packet splits, the transfer manner may be a type of the red packet, such as a split red packet or a piecemeal red packet, the type of the asset to be transferred may be a currency of digital currency to be mass texted, and the social information may be remark information of the red packet.

In some embodiments, the sender may run a client of a trading platform, which may run in dependence on H5 pages, Applications (APPs), Decentralized applications (Dapp). The user at the sending end can input the asset transfer request through the transaction platform operated by the sending end, so that the sending end can acquire the asset transfer request. In one example, a trading platform may be developed based on the H5 page and may run in a social application. The social application program may be various application programs having a social function and realizing an inter-user information technique, and may be APP such as WeChat and Messenger.

In some embodiments, if the sending end determines that the account balance of the sending end user is less than the amount of the assets to be transferred, which is input by the sending end user, the sending end user may be provided with prompt information for response through an interface of the sending end.

Step S120: and the sending end responds to the asset transfer request and sends the asset information to be transferred and the address information of the sending end to the block chain service node.

In this embodiment of the present application, a sending end may send asset information to be transferred and address information of the sending end to a block chain service node in response to an asset transfer request. The address information of the sending end may be block chain address information corresponding to the sending end.

In some embodiments, the sending end, in response to the asset transfer request, may also send asset information to be transferred, address information of the sending end, and a user identifier of a user of the sending end to the block chain service node. The user identifier of the sending-end user can be authenticated by a decentralized online identity authentication system (i.e. OpenID), so that identity information of the sending-end user does not need to be authenticated by a central website.

Step S130: and the block chain service node stores the asset information to be transferred and the address information, and generates identification information of the asset to be transferred based on the asset information to be transferred and the address information.

After the sending end sends the asset information to be transferred and the address information of the sending end to the block chain service node, the block chain service node can store the asset information to be transferred and the address information, and can generate the identification information of the asset to be transferred based on the asset information to be transferred and the address information. In one example, the identification information of the asset to be transferred may be red-packed identification information.

Step S140: the sending end obtains identification information of the assets to be transferred, which is returned by the block chain service node, and obtains state information of the assets to be transferred based on the identification information of the assets to be transferred.

In the embodiment of the application, the sending end can obtain the identification information of the assets to be transferred, which is returned by the block chain service node, and obtain the state information of the assets to be transferred based on the identification information of the assets to be transferred. In some embodiments, the sending end may query the status information of the asset to be transferred according to the identification information of the asset to be transferred, or may send the identification information of the asset to be transferred and the query instruction to the blockchain service node, and the blockchain service node queries the status information of the current asset to be transferred. The status information of the asset to be transferred can be used to indicate whether the asset to be transferred has been transferred.

In an example, the asset to be transferred is a red packet sent in a group, then the sending end may obtain the state of the red packet according to the identification information of the red packet returned by the blockchain service node, and specifically, the blockchain service node may query whether the red packet is robbed up according to the identification information of the red packet.

In some embodiments, the sending end may poll to acquire the status information of the asset to be transferred based on the identification information of the asset to be transferred.

In some embodiments, after the sending end obtains the identification information of the asset to be transferred, which is returned by the blockchain service node, the following steps may also be performed:

step S141: and the sending end generates an asset transfer link based on the identification information of the asset to be transferred and the address information of the sending end.

After the sending end obtains the identification information of the assets to be transferred, which is returned by the block chain service node, the sending end can also generate an asset transfer link based on the identification information of the assets to be transferred and the address information of the sending end, wherein the asset transfer link at least comprises the identification information of the assets to be transferred and the address information of the sending end. In one example, the asset transfer link may be a red purse sharing link.

Step S142: the sending end sends the asset transfer link to the receiving end.

In an embodiment of the present application, a sending end may send an asset transfer link to a receiving end.

In one embodiment, a trading platform may be developed based on the H5 page and may run in a social application. Thus, the sender may send the generated asset transfer link to the receiver through the social application. In one example, the sending end may generate an asset transfer link (red packet sharing link) based on identification information of an asset to be transferred and address information of the sending end, and a user of the sending end sends the red packet sharing link to a wechat window corresponding to a user of the receiving end through a wechat message, or sends the red packet sharing link to a wechat window (e.g., a group chat window) including wechat windows corresponding to a plurality of users of the receiving end, so that the user of the receiving end may receive the asset transfer link and click the asset transfer link to realize asset transfer. Therefore, the block chain transaction can be completed without manually establishing a block chain address by a receiving end user and familiarizing the block chain technology, so that the user operation threshold and difficulty are greatly reduced, and the popularization range of the block chain technology is favorably expanded.

Step S143: and the receiving terminal acquires the identification information of the assets to be transferred based on the asset transfer link and generates a temporary address.

After the receiving end receives the asset transfer link, the receiving end can acquire the identification information of the asset to be transferred based on the asset transfer link and generate a temporary address. Wherein the temporary address is a block chain address.

In some embodiments, after the receiving end receives the asset transfer link, the receiving end user may click the asset transfer link, so that the receiving end may obtain the identification information of the asset to be transferred, and generate the temporary address. And the receiving end can send the identification information of the assets to be transferred to the block chain service node, and the block chain service node inquires the state information of the assets to be transferred according to the identification information of the assets to be transferred. In one example, a receiving end user can click the red packet sharing link, the receiving end obtains identification information of the red packet based on the red packet sharing link, sends the identification information of the red packet to the blockchain service node, and the blockchain service node inquires whether the red packet is robbed up according to the identification information of the red packet. Further, if the red packet is robbed up, the information that the red packet is robbed up can be displayed on the interface of the receiving end.

Step S144: and the receiving terminal sends the temporary address, the identification information of the asset to be transferred and the account information of the receiving terminal to the block chain service node.

In this embodiment of the application, the receiving end may send the generated temporary address, the identification information of the asset to be transferred, and the account information of the receiving end to the block chain service node.

In some embodiments, after the receiving end receives the asset transfer link, a user of the receiving end may click the asset transfer link, so that the receiving end may obtain the identification information of the asset to be transferred, and then the receiving end may send the identification information of the asset to be transferred to the blockchain service node, and the blockchain service node queries the state information of the asset to be transferred according to the identification information of the asset to be transferred. When the state information of the assets to be transferred does not meet the preset state information, the receiving end can generate a temporary address and send the temporary address, the identification information of the assets to be transferred and the account information of the receiving end to the block chain service node.

In one example, a receiving end user can click the red packet sharing link, the receiving end obtains identification information of the red packet based on the red packet sharing link, sends the identification information of the red packet to the blockchain service node, and the blockchain service node inquires whether the red packet is robbed up according to the identification information of the red packet. If the red packet is robbed, the information that the red packet is robbed can be displayed on the interface of the receiving end. If the red packet is not robbed up, the receiving end can generate a temporary address and send the temporary address, the identification information of the red packet and the account information of the receiving end to the block chain service node.

Step S145: and verifying the identification information of the assets to be transferred and the account information of the receiving end by the block chain service node to obtain a verification result.

In this embodiment of the application, the blockchain service node may check the identification information of the asset to be transferred and the account information of the receiving terminal to obtain a check result, so as to determine whether to transfer a part of the asset to be transferred to the account of the receiving terminal.

In some embodiments, the asset to be transferred information may include a validity period of the asset transfer request, and the receiving end may only receive a portion of the asset to be transferred within the validity period. For example, the validity period of the asset transfer request may be a red envelope validity period, and the receiving end user can only get the red envelope within the red envelope validity period. Therefore, after receiving the identification information of the assets to be transferred, the blockchain service node can obtain the validity period of the asset transfer request through the identification information of the assets to be transferred, so as to judge whether the asset transfer request is valid.

In some embodiments, the blockchain service node may check the account information of the receiving end to determine whether the receiving end has clicked on the asset transfer link. Specifically, the account information of the receiving end may be compared with the account information stored by the blockchain service node to determine whether the account information is already stored by the blockchain service node.

In an example, the account information of the receiving end may be checked, and whether the receiving end user has robbed the red packet of the current group transmission is determined. If the receiving end user snatches the red packet sent by the group, the account information of the receiving end is stored in the block chain service node.

Step S146: and when the verification result represents that the verification is correct, the block chain service node stores the temporary address and the account information of the receiving end.

In this embodiment of the application, when the verification result indicates that the verification is correct, the blockchain service node may store the temporary address and the account information of the receiving end.

In some embodiments, the verification may be performed through the above verification method, and when the verification result indicates that the verification is correct, the verification result may indicate that the asset transfer request is not expired, or the verification result indicates that the account information of the receiving end is not stored on the blockchain service node. The blockchain service node may then store the temporary address as well as the account information for the receiving end.

Step S150: and when the state information of the assets to be transferred meets the preset state information, the sending end calls the intelligent contract.

In the embodiment of the application, when the state information of the assets to be transferred meets the preset state information, the sending end can call the intelligent contract. The status information of the assets to be transferred can be used to indicate the number of the assets to be transferred that are picked up. The preset status information may be that the assets to be transferred have been fully picked up. When the state information of the assets to be transferred meets the preset state information, the sending end can call the intelligent contract when the assets to be transferred are all picked up.

In some embodiments, when the status information of the asset to be transferred meets the preset status information, a user of the sending end can send a request for forcibly sending the asset, and after receiving the request for forcibly sending the asset, the sending end can directly call the intelligent contract.

Step S160: and the intelligent contract transfers the assets to be transferred to the accounts of the multiple receiving ends respectively based on the asset information to be transferred.

In the embodiment of the application, the intelligent contract can respectively transfer the assets to be transferred to the accounts of the multiple receiving ends based on the asset information to be transferred.

In some embodiments, when the status information of the asset to be transferred meets the preset status information, the sending end may directly submit a transaction request to the smart contract to initiate the transfer transaction. And respectively transferring the assets to be transferred to accounts of a plurality of receiving ends by the intelligent contract based on the asset information to be transferred.

The transfer operation of the smart contract is slightly different due to the difference in the currency of the digital money. In some embodiments, when the asset to be transferred is stored in the account of the sending end, the transaction request may include a block chain address of the sending end, that is, address information of the sending end, asset information to be transferred, and account information of a plurality of receiving ends, so as to generate transaction records in which a part of the asset to be transferred is transferred from the address of the sending end to the plurality of receiving ends, and then the transaction records are verified through a block chain link point of a block chain network, and after the verification is passed, the part of the asset to be transferred can be transferred from the account of the sending end to the accounts of the plurality of receiving ends. Therefore, a plurality of account transfers are packaged into one transaction, and the expense of a block chain can be saved. For example, if the digital currency is one of Bitcoin (BTC), Bitcoin Cash (BCH), ledebut coin (LTC), the asset is stored in the sender's account when the asset is to be transferred.

In some embodiments, when the type of the asset to be transferred is a primary currency, such as Ethernet (ETH), and the asset to be transferred is stored in an account of the smart contract, the smart contract transfers the asset to be transferred from the account of the smart contract to the accounts of the multiple receiving ends respectively based on the transaction request, that is, the smart contract transmits the asset to be transferred in an internal loop.

In some embodiments, when the type of the asset to be transferred is ERC20 token, the asset to be transferred is transferred to the accounts of the multiple receiving ends respectively by circularly calling the transferFrom method inside the intelligent contract.

In some embodiments, when the sender initiates a transaction request, a corresponding Gas Fee (Gas Fee) needs to be paid to ensure that the transaction is normally performed. For example, when the sending end initiates a transaction request for transferring the asset to be transferred from the sending address to the receiving end address, a miner fee is paid for paying the computing resources consumed by miners for generating new blocks, adding uplink and the like. Where the miner fee may be stored in the sender's account.

In one example, when the user a wishes to send funds to a friend group, the user a may initiate an asset transfer request (red packet group sending request) through a Decentralized Application (Dapp) of the sending end, for example, the user a may select a chain of digital money to be sent in group at a group sending interface of the Dapp, enter a group sending information filling page, select a digital money type and a red packet mode at the group sending information filling page, and input a red packet amount, a red packet number and a remark. After the user A confirms the input mass red packet sending information, the block chain service node generates the identification information of the red packet according to the information, the sending end generates the red packet robbing link, and the user A can share the red packet robbing link to friends. And after receiving the red envelope robbing link at the Dapp client, the user B, the user C and the like click the link to enter the red envelope robbing interface, and then the block chain service node of the Dapp stores the client accounts of the red envelope robbing users of the user B, the user C and the like. After the friends participate in the credit, the user A can click to pay, and a certain amount of money is randomly allocated by the intelligent contract according to the input mass red packet sending information and transferred to client accounts of the user B, the user C and other users who grab the red packet. The user A and the user who robs the red envelope can check the account condition of the red envelope, the amount of the red envelope robbed by each person and the like through the red envelope detail page of the Dapp client.

In the asset transfer method provided by the above embodiment, the sending end receives an asset transfer request, where the asset transfer request includes asset information to be transferred; the sending end responds to the asset transfer request and sends the asset information to be transferred and the address information of the sending end to the block chain service node; the block chain service node stores the asset information to be transferred and the address information, and generates identification information of the asset to be transferred based on the asset information to be transferred and the address information; a sending end acquires identification information of assets to be transferred, which is returned by a block chain service node, and acquires state information of the assets to be transferred based on the identification information of the assets to be transferred; when the state information of the assets to be transferred meets the preset state information, the sending end calls an intelligent contract; and the intelligent contract transfers the assets to be transferred to the accounts of the multiple receiving ends respectively based on the asset information to be transferred. Therefore, when the state information of the assets to be transferred meets the preset state information, the intelligent contract is called, so that the assets to be transferred are transferred by the intelligent contract, the batch transfer of the assets is realized, the block chain overhead is saved, and the batch transfer of the assets is more rapid and convenient.

In some embodiments, when the type of asset is not a primary currency of the backbone, but an ERC20 token, the contract advance method of ERC20 token may be invoked to authorize the asset to be transferred so that the intelligent contract of the present application may conduct asset transfer transactions.

In some embodiments, the sender user may retrieve the asset that has been recharged at any time. Specifically, the extraction transaction request may be constructed, and if the type of the asset is the primary currency, the asset in the account of the intelligent contract may be extracted into the account of the sending end according to the extraction transaction request. If the asset type is ERC20 token, a transferFrom may be invoked to transfer the token to the sender's account based on the extract transaction request.
