Please refer to fig. 3, which is a flowchart illustrating an asset transfer method based on a blockchain according to an embodiment of the present application. As shown in fig. 3, the method may include:
step S101, asset transfer information sent by a first user terminal is obtained; the asset transfer information comprises first user information, asset transfer amount, second user information and transfer initiation time corresponding to the first user terminal.
In this application, the first user may be a donor who wants to perform asset donation, and the asset transfer information may be donation information input in the asset donation platform when the first user accesses the asset donation platform through the first user terminal. The first user terminal sends the access request of the first user to the block chain node, the block chain node can determine the user attribute information of the first user after detecting the access request, the user attribute information may include information such as a user ID, a user name, a user gender and a user address, according to the user attribute information of the user, the block link point can check the authority of the first user, such as passing the check, the block link point may determine that the first user is a qualified donor, the block link point may transmit an operation page for inputting asset transfer information to the first user terminal, the first user may input asset transfer information in the operation page, i.e., donation information, which includes donor information (i.e., first user information), the amount of donation (i.e., the asset transfer amount), the donated person (i.e., second user information), and the time of donation (i.e., the transfer initiation time), etc.
Step S102, according to the asset transfer information, triggering an intelligent contract to acquire a source asset belonging to the first user information; the source assets are the assets corresponding to the asset transfer amount.
In the method, a first user terminal can sign asset transfer information input by a first user based on a private key to obtain a digital signature, the first user terminal can send the asset transfer information carrying the digital signature to a block chain node, the block chain node can obtain a public key of the first user terminal, the public key is adopted to check and sign the asset transfer information, when the check and sign pass, the block chain node can determine the digital signature as a legal signature, and then the block chain node can trigger an intelligent contract according to the asset transfer information to obtain source assets belonging to the first user. The source asset corresponds to the asset transfer amount (donation amount), and if the asset transfer amount input by the first user is 1000 yuan, the block link point may obtain 1000 yuan from the account of the first user, and the 1000 yuan obtained from the first user is the source asset.
Step S103, sending the source asset to a second user terminal corresponding to the second user information, and acquiring response information returned by the second user terminal based on the source asset.
In this application, the block link point may send the source asset to a second user terminal corresponding to the second user information, so as to transfer the source asset, and the second user terminal may return response information to the block link point when receiving the source asset. If the second user terminal successfully receives the source asset and can use the source asset, the response message is that the source asset is successfully received; if the second user terminal receives the source asset but an abnormal condition occurs (for example, the second user information is abnormal, the source asset cannot be normally used, etc.), the response information is reception failure information to prompt the blockchain node that the source asset is failed to transfer.
Step S104, if the response message indicates that the source asset is successfully received, determining that the second user message has the right to use the source asset, determining a transfer route between the first user message and the second user message, the transfer initiation time, and the response message as first asset flow direction messages, and linking the first asset flow direction messages to a block chain.
In this application, when the response message is that the source asset is successfully received, the block link point may determine that the second user information has the usage right of the source asset, that is, the second user may normally use the source asset, and determine a transfer route between the first user information and the second user information, where the transfer route may be an asset transfer direction between the first user information and the second user information, the first user information, and the second user information, for example, the transfer route may be as shown in { user a, user B, an account address of user a points to an account address of user B } in the first asset transfer information in the embodiment corresponding to fig. 2, and the block link point may determine the transfer route, the transfer initiation time, and the response message as the first asset flow direction information, the blockchain node may send the first asset flow direction information to all consensus nodes in the blockchain, and after all consensus nodes pass consensus verification, the blockchain node may link the first asset flow direction information into the blockchain.
Optionally, if the first user selects anonymity after inputting the asset transfer information, the first user terminal generates an anonymity prompt message and sends the anonymity prompt message and the asset transfer information to a block link node, the block link node may obtain a public key of the first user terminal according to the anonymity prompt message, encrypt the first user information by using the public key to obtain a first user information ciphertext, and the block link node may determine the first user information ciphertext, the second user information, and an asset transfer direction between the first user information and the second user information as a transfer route.
The above description shows that, the asset transfer information of the first user terminal is obtained, the intelligent contract is triggered to send the source asset from the first user information to the second user terminal, and after the second user terminal successfully receives the source asset, the first user information can be linked to the asset flow direction information of the second user information.
Please refer to fig. 4a and fig. 4b, which are schematic scene diagrams of another block chain-based asset transfer method according to an embodiment of the present application. As shown in fig. 4a, terminal a may be a first user terminal, terminal a may send asset transfer information to a blockchain node, where the asset transfer information may be the asset transfer information in the embodiment corresponding to fig. 2, an asset transfer amount in the asset transfer information is 5000, and a blockchain node may obtain 5000 yuan of a source asset belonging to user a according to the asset transfer amount, and then send 5000 yuan to terminal B (i.e., a second user terminal), and after receiving response information that is successfully received and returned by terminal B, the blockchain node may compare the asset transfer amount with an asset transfer amount threshold, where the asset transfer amount threshold may be an artificially set value, and if the artificially set asset transfer amount threshold is 3000, the blockchain node may determine that the asset transfer amount 5000 is greater than the asset transfer amount threshold 3000, the blockchain node may generate an advertisement message based on the asset transfer amount, as shown in fig. 4a, the announcement message may be "thank you user a compelling for generous contribution of 5000 yuan", and the block link point may send the announcement message to the management background, so that the management background broadcasts the announcement message to the user terminal cluster "user terminal 100a, user terminals 100b, …, and user terminal 100 c", thereby achieving the advertising effect.
As shown in fig. 4a, a block chain node may obtain the usage of the source asset by the user B, so as to generate second asset flow information, as shown in fig. 4a, the second asset flow information transfers the source asset to the user C for the user B, that is, the asset flow of the source asset flows to the user C for the user B, and the block chain node may generate a block 1002 according to the second asset flow information, and chain the block 1002 to the block chain 100. When the block link point receives the request for querying the asset flow direction sent by the terminal a, the block link point may obtain the block 1002 from the block chain 100, so as to obtain the second asset flow direction information, and the block link point may send the second asset flow direction information to the terminal a, so that the terminal a determines the usage record of the terminal B for the source asset according to the second asset flow direction information.

The block chain node may acquire a transfer record from the second user terminal to another user terminal, and generate second asset flow direction information, and the block chain node may generate a block according to the second asset flow direction information and chain the block into the block chain.
Step S202, when receiving the request for inquiring the asset flow direction sent by the first user terminal, acquiring second asset flow direction information from the block chain based on the request for inquiring the asset flow direction.
