[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In one embodiment, if Figure 1 As shown, an asset transaction method based on a blockchain system is provided. The blockchain system includes multiple basic users and multiple blockchain transaction party nodes. Each of the basic users can belong to multiple blockchain transaction party nodes. The basic user is a user of the blockchain transaction party node. The basic user can be a user on multiple blockchain transaction party nodes. Blockchain transaction party nodes can conduct transactions through basic users.

[0030] Hereinafter, this method is described with the first blockchain transaction party node in the blockchain system as the execution subject, and the method includes the following steps:

[0031] S10, receiving a transaction request sent by a basic user.

[0032] Among them, the transaction request carries the user information of the basic user, the transaction goods and the transaction amount and transaction method information corresponding to the transaction goods; the basic user is the transaction user of the first blockchain transaction party node, and the transaction request is used to realize the transaction between the basic user and the first blockchain transaction party node. It should be noted that the basic user is an ordinary user on each transaction platform, and each basic user can apply for a corresponding user account on different platforms, that is, each basic user can belong to a different blockchain transaction party node. The user information of the basic user can specifically be the user's name, account number, delivery address, etc.; the transaction method information is specifically the payment method of the basic user for the transaction, which can be bank card payment, WeChat payment, Alipay payment, etc., which is not specifically limited in the embodiment of the present invention.

[0033] S20, obtaining user information and transaction method information of the basic user from the transaction request.

[0034] In one embodiment provided by the present invention, before receiving the transaction request sent by the basic user, the method further includes: obtaining a user account registration request sent by the basic user; the user account registration request includes the user information and the user account; verifying whether the user information and the user account correspond correctly; if the user information and the user account correspond correctly, the user information and user account of the basic user are stored in the first blockchain transaction party node. Among them, the user account is the payment account of the basic user, and the verification of the user information and user account is to determine whether the user information entered by the basic user can correspond to the user account, that is, to confirm whether the basic user has the authority to realize payment behavior through the user account.

[0035] Correspondingly, such as Figure 2 As shown, step S20 obtains the user information and transaction method information of the basic user from the transaction request, including:

[0036] S201, query whether there is user information and user account corresponding to the basic user in the first blockchain transaction party node.

[0037] In an embodiment of the present invention, after verifying that the user information and the user account correspond correctly, the first blockchain transaction party node stores the user information and user account of the basic user in the first blockchain transaction party node, so that after receiving the transaction request sent by the basic user, it is convenient to query whether the user information and user account corresponding to the basic user exist in the first blockchain transaction party node. If so, it means that the basic user is a registered user of the first blockchain transaction party node, and the user information and transaction method information of the basic user can be obtained from the transaction request in subsequent steps.

[0038] S202: If there is user information and a user account corresponding to the basic user, the user information and transaction method information of the basic user are obtained from the transaction request.

[0039] For the embodiment of the present invention, after receiving the transaction request sent by the basic user, it is queried whether there is user information and user account corresponding to the basic user. If there is user information and user account corresponding to the basic user, it means that the basic user is a registered user of the first blockchain transaction party node. At this time, the user information and transaction method information of the basic user are obtained from the transaction request, which can ensure the efficiency of obtaining the user information and transaction method information of the basic user, so as to realize the transaction between the basic user and the first blockchain transaction party node in the subsequent steps.

[0040] S30, determining the second blockchain transaction party node corresponding to the first blockchain transaction party node according to the transaction method information, and confirming whether the second blockchain transaction party node contains a user account corresponding to the user information of the basic user.

[0041] It should be noted that the transaction method identification information contained in the transaction method information, the transaction method information and the second blockchain transaction party node, can uniquely determine the corresponding second blockchain transaction party node through the transaction method information. After determining the second blockchain transaction party node corresponding to the transaction method information, check whether the second blockchain transaction party node contains the user account corresponding to the user information of the basic user. For example, after the basic user A sends a transaction request to the first blockchain transaction party node, the second blockchain transaction party node corresponding to the first blockchain transaction party node is determined according to the transaction method information in the transaction request, and then check whether the second transaction party node contains the user account of the basic user A.

[0042] S40, if it is confirmed that the second blockchain transaction party node contains a user account corresponding to the user information of the basic user, the transaction amount is obtained from the transaction request, and a smart contract is generated based on the user account corresponding to the user information in the second blockchain transaction party node as the payment account, transaction amount and the receiving account corresponding to the first blockchain transaction party node.

[0043] It should be noted that before generating a smart contract based on the user account corresponding to the user information in the second blockchain transaction party node as the payment account, the transaction amount and the receiving account corresponding to the first blockchain transaction party node, the method also includes: the second blockchain transaction party node sends a CA digital certificate acquisition request to the authoritative agency server, and the CA digital certificate acquisition request includes the user information of the basic user, so that the authoritative agency server performs KYC review on the basic user according to the user information of the basic user; the second blockchain transaction party node receives the CA digital certificate sent by the authoritative agency server, the CA digital certificate includes the user information of the basic user, and the CA digital certificate is a certificate that has passed the KYC review.

[0044] It should be noted that since the second blockchain transaction party is the node where the actual payment behavior occurs, the second blockchain transaction party node needs to obtain the CA digital certificate. Specifically, the CA digital certificate acquisition request sent by the second blockchain transaction party node to the authority server may contain the user information of multiple basic users, that is, the CA digital certificate acquisition request sent by the second blockchain transaction party node at one time can realize the KYC review of multiple basic users.

[0045] Correspondingly, such as Figure 3 As shown, the generating of a smart contract based on the user account corresponding to the user information in the second blockchain transaction party node as the payment account, the transaction amount and the payment account corresponding to the first blockchain transaction party node includes:

[0046] S401, obtain the CA digital certificate of the second blockchain transaction node, and detect whether the CA digital certificate contains user information of the basic user.

[0047] The CA digital certificate contains a public key. Users can trust the CA by verifying its signature. Anyone can obtain a CA digital certificate to verify the certificate it issued. The CA digital certificate binds the public key to the applicant's user identity information, signs it, and then forms a certificate and sends it to the applicant.

[0048] S402: If the CA digital certificate contains user information of the basic user, a smart contract is generated based on the user account corresponding to the user information in the second blockchain transaction party node as the payment account, transaction amount and the receiving account corresponding to the first blockchain transaction party node.

[0049] In the embodiment of the present invention, the CA digital certificate of the second blockchain transaction node is obtained, and it is detected whether the CA digital certificate contains the user information of the basic user. If the CA digital certificate contains the user information of the basic user, a smart contract is generated based on the user account corresponding to the user information in the second blockchain transaction party node as the payment account, transaction amount and the receiving account corresponding to the first blockchain transaction party node. In the subsequent steps, the second blockchain transaction party node can execute the operation of paying the transaction amount from the payment account to the receiving account according to the smart contract.

[0050] S50, sending the smart contract to the second blockchain transaction party node, so that the second blockchain transaction party node executes the operation of paying the transaction amount from the payment account to the payment account according to the smart contract.

[0051] S60: If it is determined that the operation of the payment account paying the transaction amount to the payment account is successful, then the transaction between the basic user and the first blockchain transaction party node is confirmed to be successful.

[0052] The present invention provides an asset transaction method based on a blockchain system. The blockchain system includes multiple basic users and multiple blockchain transaction party nodes. Each basic user can belong to multiple blockchain transaction party nodes. First, a transaction request sent by a basic user is received, and user information and transaction method information of the basic user are obtained from the transaction request; and a second blockchain transaction party node corresponding to a first blockchain transaction party node is determined according to the transaction method information; if it is confirmed that the second blockchain transaction party node contains a user account corresponding to the user information of the basic user, the transaction amount is obtained from the transaction request, and a smart contract is generated according to the user account corresponding to the user information in the second blockchain transaction party node as a payment account, a transaction amount and a receiving account corresponding to the first blockchain transaction party node; the smart contract is sent to the second blockchain transaction party node, so that the second blockchain transaction party node executes an operation of the payment account paying the transaction amount to the receiving account according to the smart contract; if it is determined that the operation of the payment account paying the transaction amount to the receiving account is successful, the transaction between the basic user and the first blockchain transaction party node is confirmed to be successful. Compared with the current process of asset transactions involving three parties in a blockchain system, which requires every two parties to confirm whether the transaction is successful, the present invention only needs to confirm that the transaction between the first blockchain transaction party node and the second blockchain transaction party node is successful, and then the asset transaction involving the three parties can be determined. Therefore, the asset transaction efficiency of the blockchain system can be improved through the present invention.

[0053] In one embodiment provided by the present invention, in order to ensure the security of the smart contract, after generating a smart contract based on the user account corresponding to the user information in the second blockchain transaction party node as the payment account, the transaction amount and the receiving account corresponding to the first blockchain transaction party node, the method also includes: performing a hash calculation based on the user information of the basic user and the receiving account corresponding to the first blockchain transaction party node to obtain a smart contract encryption key; and encrypting the smart contract using the smart contract encryption key.

[0054] Correspondingly, after receiving the encrypted smart contract, the second blockchain transaction party node first obtains the user information of the basic user and the receiving account corresponding to the first blockchain transaction party node that needs to make payment, and then performs hash calculation on the user information of the basic user and the receiving account corresponding to the first blockchain transaction party node to obtain the decryption key of the smart contract, and then decrypts the smart contract through the decryption key, and executes the operation of paying the transaction amount from the payment account to the receiving account based on the content in the smart contract, thereby ensuring the security of asset transactions.

[0055] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.
