That is, each resource management server 301 of the plurality of resource management servers 301 can access the blockchain system 302 . Each resource management server 301 of the plurality of resource management servers 301 is used for resource management. The resource may be a resource with circulating value, for example, the resource may be currency, in this case, the plurality of resource management servers 301 may be servers of various financial institutions (eg, banks).

In a possible scenario, any two resource management servers 301 in the multiple resource management servers 301 are located in different regions, and resources used in different regions are different. For example, any two resource management servers 301 in the multiple resource management servers 301 are located in different organizations or countries, and different organizations or countries have different currencies. In this case, the resource transfer between any two resource management servers 301 in the plurality of resource management servers 301 is a cross-border payment.

For any one resource management server 301 of the plurality of resource management servers 301, a user can register a resource account in the resource management server 301, and the user can deposit resources into the resource account or withdraw resources from the resource account. For example, a user may register a bank account in a server of a bank, and the user may deposit money into or withdraw money from the bank account. Each resource management server 301 may register a corresponding blockchain account for its resource account in the blockchain system 302 .

The plurality of resource management servers 301 include a target resource management server 3011 and other resource management servers 3012 except the target resource management server 3011 , and the number of other resource management servers 3012 may be greater than or equal to two. The target resource management server 3011 may be the token issuer's resource management server. Other resource management servers 3012 may be non-token issuer resource management servers. In this embodiment of the present application, the target resource management server 3011 may be deployed in a region qualified for token issuance, other resource management servers 3012 may be deployed in other regions, and different resource management servers 3012 may be deployed in different regions.

The target resource management server 3011 may register a resource account in each of the other resource management servers 3012, and the resource account may be called a target account or a settlement account. That is, the target resource management server 3011 has a plurality of target accounts. The target resource management server 3011 may register a blockchain account in the blockchain system 302, and the blockchain account may be referred to as a target blockchain account.

A blockchain account is an account that exists on the blockchain configured by the blockchain system 302 . That is, the account data of the blockchain account is stored in the blockchain configured by the blockchain system 302 . The account data of the blockchain account can include account address, balance, state variables, etc. The balance of the blockchain account represents the number of tokens owned by the blockchain account.

The other resource management servers 3012 include a first resource management server and a second resource management server. The first resource management server, the second resource management server, the target resource management server 3011 and the blockchain system 302 can execute the resource transfer method described in the embodiment of FIG. 4 below to realize the transfer between resource accounts in different resource management servers. resource transfer.

The resource transfer method provided by the embodiment of the present application will be explained in detail below.

FIG. 4 is a flowchart of a resource transfer method provided by an embodiment of the present application. Referring to Figure 4, the following steps are included.

The resource management server can register the corresponding blockchain account for the resource account in the blockchain system. The following takes the first resource management server and the second resource management server as examples to describe the blockchain account registration process, which may include the following steps 401-404. Among them, steps 401 and 402 are that the first resource management server registers the corresponding blockchain account for the first resource account in the blockchain system, and steps 403 and 404 are that the second resource management server is the second resource management server in the blockchain system. The resource account registers the corresponding blockchain account.

Step 401: The first resource management server sends a blockchain account registration request to the blockchain system, where the blockchain account registration request carries the first resource account identifier.

The blockchain account registration request is used to request to register the blockchain account corresponding to the first resource account. The first resource account identifier is used to identify the first resource account, for example, the first resource account identifier may be the serial number of the first resource account or the like. The first resource account is a resource account registered by the user in the first resource management server. For example, when the first resource management server is a server of a bank, the first resource account may be a bank account registered by the user in the server of the bank, and the first resource account identifier may be the account number of the bank account.

The user may initiate a blockchain account registration application to the first resource management server through the first resource management client, where the blockchain account registration application includes the first resource account identifier and user information. After receiving the blockchain account registration application, the first resource management server may send the blockchain account registration request to the blockchain system. Optionally, after receiving the blockchain account registration application, the first resource management server may review the blockchain account registration application first, and then send the blockchain account registration application to the blockchain system after the review is passed. ask.

The first resource management server may review the blockchain account registration application automatically. For example, the first resource management server may review the blockchain account registration application according to preset registration conditions. Specific business needs are preset. If the blockchain account registration application satisfies the registration conditions, the first resource management server determines that the blockchain account registration application is approved; if the blockchain account registration application does not meet the registration conditions, the first resource management server It is determined that the application for registration of the blockchain account has not been approved.

Alternatively, the first resource management server may review the blockchain account registration application manually, for example, the first resource management server may review the blockchain account registration application. When the staff member determines that there is no problem with the blockchain account registration application, he can trigger an approval instruction. After detecting the approval instruction, the first resource management server determines that the blockchain account registration application is approved; the staff member determines When there is a problem with the blockchain account registration application, a review failure instruction may be triggered, and the first resource management server determines that the blockchain account registration application review fails after detecting the review failure command.

Step 402: The blockchain system registers the corresponding first blockchain account for the first resource account.

Specifically, after receiving the blockchain account registration request sent by the first resource management server, the blockchain system can generate a first blockchain account, and the account data of the first blockchain account includes the account address and balance; The first resource account identifier carried in the blockchain account registration request is stored corresponding to the account address of the first blockchain account. After the first resource account identifier is stored corresponding to the account address of the first blockchain account, the first resource account is bound to the first blockchain account.

The operation of generating the first blockchain account by the blockchain system is similar to the operation of generating a certain blockchain account by the blockchain system in the related art, which is not described in detail in this embodiment of the present application.

Step 403: The second resource management server sends a blockchain account registration request to the blockchain system, where the blockchain account registration request carries the second resource account identifier.

The blockchain account registration request is used to request to register the blockchain account corresponding to the second resource account. The second resource management server and the first resource management server are different resource management servers. Optionally, the regions where the first resource management server and the second resource management server are located are different. For example, the first resource management server and the second resource management server may be deployed in different organizations or countries. In this case, the resource transfer between the resource account in the first resource management server and the resource account in the second resource management server is Cross-border payments.

The second resource account identifier is used to identify the second resource account, for example, the second resource account identifier may be the serial number of the second resource account or the like. The second resource account is a resource account registered by the user in the second resource management server. For example, when the second resource management server is a server of a bank, the second resource account may be a bank account registered by the user in the server of the bank, and the second resource account identifier may be the account number of the bank account.

The operation of the second resource management server sending the blockchain account registration request to the blockchain system is similar to the operation of the first resource management server sending the blockchain account registration request to the blockchain system in the above step 401. No longer.

Step 404: The blockchain system registers the corresponding second blockchain account for the second resource account.

The operation of step 404 is similar to the operation of the blockchain system to register the first blockchain account corresponding to the first resource account in the foregoing step 402, which is not described in detail in this embodiment of the present application.

Further, after the blockchain system registers the corresponding blockchain account for the resource account in the resource management server, the blockchain system can also set the resource account according to the resource transfer situation between the resource account and its corresponding target account. The balance of the corresponding blockchain account. The resource account is the first resource account or the second resource account.

The resource account and its corresponding target account are registered in the same resource management server. The resource account is obtained by the user registered with a resource management server, and the target account corresponding to the resource account is obtained by the target resource management server registered with the resource management server. All resource accounts in a resource management server correspond to a target account in the resource management server, that is, the target account corresponding to a resource account is the target account in the resource management server to which the resource account belongs. Resource transfer can be performed directly between resource accounts and target accounts belonging to the same resource management server. For example, transfers can be made directly between multiple bank accounts belonging to a server of the same bank.

In a possible situation, the blockchain system may set the balance of the blockchain account corresponding to the resource account according to the resource transfer situation between the resource account and the corresponding target account. The operation of recharging the resource account for the blockchain account. Funding the blockchain account is storing tokens in the blockchain account.

The following will take the user to which the first resource account belongs to recharge its corresponding blockchain account through the first resource account as an example for description, and the specific process may include the following steps 405-407. The process of recharging the corresponding blockchain account of the user to which the second resource account belongs through the second resource account is similar, which is not repeated in this embodiment of the present application.

Step 405: The first resource management server sends a token storage request to the blockchain system.

The token storage request carries the quantity of the second resource to be stored by the first resource account. Specifically, the token storage request may include a first resource account identifier and a second resource quantity.

The user can initiate a token storage application to the first resource management server through the first resource management client, and the token storage application includes the first resource account identifier, user information, and the quantity of the second resource to be stored. After receiving the token storage application, the first resource management server can send the token storage request to the blockchain system. Optionally, after receiving the token storage application, the first resource management server may review the token storage application first, and then send the token storage request to the blockchain system after the verification is passed.

The first resource management server may review the token storage application automatically. For example, the first resource management server may review the token storage application according to preset storage conditions, and the storage conditions may be based on specific business needs. Make a preset. If the token storage application satisfies the storage condition, the first resource management server determines that the token storage application is approved; if the token storage application does not meet the storage condition, the first resource management server determines the token storage application Review failed.

Alternatively, the first resource management server may review the token storage application manually, for example, the token storage application may be reviewed by the staff of the first resource management server. When the staff member determines that there is no problem with the token storage application, he can trigger the approval instruction. After detecting the approval instruction, the first resource management server determines that the token storage application is approved; the staff member confirms that the token storage application is approved. When there is a problem with the application, a review failure instruction can be triggered. After detecting the review failure instruction, the first resource management server determines that the token storage application has failed the review.

Step 406: After receiving the token storage request sent by the first resource management server, the blockchain system transfers the resources of the second resource quantity in the first resource account to the target account corresponding to the first resource account.

In this case, the resources in the first resource account are transferred to the target account in the same resource management server as the first resource account.

Specifically, after the blockchain system receives the token storage request sent by the first resource management server, the first resource account identifier, the second resource quantity and the target account corresponding to the first resource management server carried in the token storage request Identifies, and calls the resource transfer interface provided by the first resource management server to transfer the resources of the second resource quantity in the first resource account to the target account in the first resource management server, which is also transferred to the corresponding first resource account. in the target account.

A target account is registered in each resource management server. The blockchain system can pre-store the target account identifier corresponding to each resource management server. For a certain resource management server, the target account identifier corresponding to the resource management server is used to identify the target account in the resource management server. For example, the target account identifier may be the serial number of the target account. The target account in the resource management server is the target account corresponding to the resource account in the resource management server.

Step 407: The blockchain system determines the number of second tokens corresponding to the number of second resources, and transfers the tokens of the second number of tokens in the balance of the target blockchain account to the balance of the first blockchain account .

In this case, the tokens in the target blockchain account are transferred to the first blockchain account.

There can be a certain conversion rate between the number of resources and the number of tokens. For example, the conversion rate can be set to 1:1. In this case, the number of resources and the number of tokens are the same. Of course, other conversion rates may also be set, which may be specifically set according to business requirements, which are not limited in this embodiment of the present application.

Wherein, after receiving the token storage request sent by the first resource management server, the blockchain system can determine the account address corresponding to the first resource account identifier carried in the token storage request, and will determine the area to which the acquired account address belongs. The blockchain account is used as the first blockchain account corresponding to the first resource account.

Among them, the operation of the blockchain system to transfer the tokens of the second number of tokens in the balance of the target blockchain account to the balance of the first blockchain account is to reduce the number of tokens in the balance of the target blockchain account Tokens with the second number of tokens are added to the balance of the first blockchain account with the second number of tokens.

The target blockchain account is registered in the blockchain system by the target resource management server. As the resource management server of the token issuer, the target resource management server can pre-store a large number of tokens in the target blockchain account for use in resource transfer between resource accounts of different resource management servers.

In the embodiment of this application, the blockchain system may first transfer the resources in the first resource account to the target account in the same resource management server as the first resource account, and then transfer the tokens in the target blockchain account into the first blockchain account corresponding to the first resource account. In this way, the effect of using the resources in the first resource account to store tokens in the first blockchain account corresponding to the first resource account is achieved, that is, the recharging of the first blockchain account is realized.

Further, after the user who belongs to the resource account recharges the blockchain account corresponding to the resource account through the resource account, he can use the balance in the blockchain account to perform the resource transfer operation.

The following description will be given by taking the transfer of resources from the first resource account to the second resource account as an example, and the specific process may include the following steps 408-409. The process of transferring resources from the second resource account to the first resource account is similar, which is not repeated in this embodiment of the present application.

Step 408: The first resource management server sends a resource transfer request to the blockchain system.

The resource transfer request is used to request resource transfer. The resource transfer request carries the first resource quantity to be transferred from the first resource account to the second resource account. Specifically, the resource transfer request may carry the resource account identifier of the payer (that is, the first resource account identifier), the resource account identifier of the payee (that is, the second resource account identifier), and the quantity of the first resource to be transferred.

The user can initiate a resource transfer application to the first resource management server through the first resource management client, where the resource transfer application includes the first resource account identifier, the second resource account identifier, user information, and the quantity of the first resource to be transferred. After receiving the resource transfer application, the first resource management server may send the resource transfer request to the blockchain system. Optionally, after receiving the resource transfer application, the first resource management server may review the resource transfer application first, and then send the resource transfer request to the blockchain system after the review is passed.

The first resource management server may review the resource transfer application automatically. For example, the first resource management server may review the resource transfer application according to preset transfer conditions, and the transfer conditions may be pre-determined according to specific business requirements. set up. If the resource transfer application satisfies the transfer condition, the first resource management server determines that the resource transfer application is approved; if the resource transfer application does not meet the transfer condition, the first resource management server determines that the resource transfer application is not approved.

Alternatively, the first resource management server may review the resource transfer application manually, for example, the resource transfer application may be reviewed by the staff of the first resource management server. When the staff member determines that there is no problem with the resource transfer application, he can trigger an approval instruction. After detecting the approval instruction, the first resource management server determines that the resource transfer application is approved; the staff member determines that there is a problem with the resource transfer application. When the verification fails, the first resource management server determines that the resource transfer application fails to pass the verification after detecting the verification failure instruction.

Step 409: After receiving the resource transfer request sent by the first resource management server, the blockchain system determines the number of first tokens corresponding to the first resource quantity, and calculates the first token in the balance of the first blockchain account. A number of tokens are transferred to the balance of the second blockchain account.

Wherein, after receiving the resource transfer request sent by the first resource management server, the blockchain system can determine the account address corresponding to the first resource account identifier carried in the resource transfer request, and record the blockchain to which the acquired account address belongs. The account is used as the first blockchain account corresponding to the first resource account. And, the blockchain system can determine the account address corresponding to the second resource account identifier carried in the resource transfer request, and use the blockchain account to which the acquired account address belongs as the second blockchain account corresponding to the second resource account .

Among them, the operation of the blockchain system to transfer the tokens of the first number of tokens in the balance of the first blockchain account to the balance of the second blockchain account is in the balance of the first blockchain account Decrease the number of tokens of the first token and increase the number of tokens of the first token in the balance of the second blockchain account.

Further, after the blockchain system receives the resource transfer request sent by the first resource management server, after determining the number of first tokens corresponding to the first resource quantity, the first token is stored in the balance of the first blockchain account. Before the number of tokens is transferred to the balance of the second blockchain account, the resource transfer request can also be reviewed; after the resource transfer request is reviewed and approved, the first generation corresponding to the first resource number can be determined. The number of coins in the first blockchain account is transferred to the balance of the second blockchain account; after the resource transfer request fails to pass the review, the operation is ended.

For example, when the blockchain system audits the resource transfer request, the state of the resource transfer request may be set as pending, and the resource transfer request may be stored in the database. Then, the blockchain system can store the resource transfer request to the blockchain configured by the blockchain system, and after obtaining the execution result of the on-chain transaction, send the resource transfer request to the operation server, and the operation server will transfer the resource Request for review. After the operation server approves the resource transfer request, it can change the status of the resource transfer request to reviewed, and then send the resource transfer request to the blockchain system. After receiving the resource transfer request, the blockchain system can change the status of the resource transfer request stored in the database to reviewed.

Among them, when the blockchain system sends the resource transfer request to the operation server, it can pass the MQ (Message Queuing, message queue) message middleware sends the resource transfer request to the operation server. Of course, the blockchain system can also send the resource transfer request to the operation server in other ways, which is not limited in this embodiment of the present application.

The operation server can be a server of a third-party regulatory agency, and can be responsible for the audit of resource transfers between resource accounts in different resource management servers, so as to determine that the resource transfers between resource accounts in different resource management servers are normal and safe. .

Wherein, when the operation server examines the resource transfer request, the staff of the operation server may conduct an initial review of the resource transfer request, and after the initial review is passed, the operation server may send the resource transfer request to the second resource management server , the second resource management server conducts a second review of the resource transfer request, and after the second review is passed, the operation server may determine that the resource transfer request is approved.

For example, when the blockchain system transfers the first number of tokens in the balance of the first blockchain account to the balance of the second blockchain account, it can first determine whether the resource transfer request has been processed before. However, if it is determined that the resource transfer request has not been processed, the tokens of the first number of tokens in the balance of the first blockchain account can be transferred to the balance of the second blockchain account. Afterwards, if the tokens of the first number of tokens in the balance of the first blockchain account are successfully transferred to the balance of the second blockchain account, the blockchain system can modify the status of the resource transfer request to Processing is complete.

If the first number of tokens in the balance of the first blockchain account is not successfully transferred to the balance of the second blockchain account, the blockchain system can determine the reason for the transaction failure (such as transaction timeout), Retry to transfer the first number of tokens in the balance of the first blockchain account to the balance of the second blockchain account according to the reason for the transaction failure.

In the embodiment of this application, when the blockchain system receives a resource transfer request from the first resource account to the second resource account, it transfers the tokens in the first blockchain account corresponding to the first resource account to the second resource account. In the second blockchain account corresponding to the resource account. In this way, the resource transfer between resource accounts in different resource management servers is converted into the token transfer between different blockchain accounts in the blockchain system. On the one hand, it can speed up process processing, improve resource transfer efficiency, and at the same time avoid exchange losses in related technologies. On the other hand, the immutability of the blockchain can reduce the risk of resource transfer. Once a problem occurs, it can accurately trace the source and locate the specific process point and responsible person of the problem, which is safe and reliable.

In a possible situation, the blockchain system may set the balance of the blockchain account corresponding to the resource account according to the resource transfer situation between the resource account and the corresponding target account. The operation of withdrawing from the blockchain account to the resource account. Withdrawing to the resource account is to transfer resources to the resource account.

The following is an example of a user who belongs to the second resource account withdrawing money from the blockchain account corresponding to the second resource account to the second resource account. The specific process may include the following steps 410-412. The process of withdrawing money from the blockchain account corresponding to the first resource account to the first resource account by the user to which the first resource account belongs is similar, which is not repeated in this embodiment of the present application.

Step 410: The second resource management server sends a resource extraction request to the blockchain system.

The resource extraction request carries the quantity of the third resource to be extracted by the second resource account. Specifically, the resource extraction request may include a second resource account identifier and a third resource quantity.

The user can initiate a resource extraction application to the second resource management server through the second resource management client, where the resource extraction application includes the second resource account identifier, user information, and the quantity of the third resource to be extracted. After receiving the resource extraction application, the second resource management server may send the resource extraction request to the blockchain system. Optionally, after receiving the resource extraction application, the second resource management server may review the resource extraction application first, and then send the resource extraction request to the blockchain system after the review is passed. The operation of the second resource management server to review the resource extraction application is similar to the operation of the first resource management server to review the resource transfer application in the foregoing step 408 , which is not repeated in this embodiment of the present application.

Step 411: After receiving the resource extraction request sent by the second resource management server, the blockchain system determines the number of third tokens corresponding to the number of third resources, and calculates the number of third tokens in the balance of the second blockchain account. A number of tokens are transferred to the balance of the target blockchain account.

In this case, the tokens in the second blockchain account are transferred to the target blockchain account.

Wherein, after receiving the resource extraction request sent by the second resource management server, the blockchain system can determine the account address corresponding to the second resource account identifier carried in the resource extraction request, and record the blockchain to which the acquired account address belongs.

In this way, the effect of extracting the tokens in the second blockchain account corresponding to the second resource account as resources in the second resource account is achieved, that is, the withdrawal to the second resource account is realized.

Further, since the target account is the resource account registered by the target resource management server in other resource management servers, that is, the target resource management server is the resource management server to which the target account belongs, so in the embodiment of the present application, the relevant target account can also be The resource transfer record is notified to the target resource management server to facilitate subsequent account reconciliation by the target resource management server. Specifically, the following steps 413-414 may be included.

Step 413: The blockchain system generates a resource transfer record of the target account according to the resource transfer situation between the resource account and the corresponding target account.

The resource transfer record of the target account is used to record the resource transfer out and resource transfer in the target account. For example, the target account resource transfer record may record the above-mentioned situation of transferring resources in the first resource account to the target account, or the target account resource transfer record may record the above-mentioned situation of transferring resources in the target account to the second resource account. Every time a resource transfer occurs in the target account (including resource transfer or resource transfer), the blockchain system can generate a target account resource transfer record according to the current resource transfer situation of the target account.

Step 414: The blockchain system sends the target account resource transfer record to the target resource management server.

Specifically, the blockchain system can send the target account resource transfer record to the billing account (including but not limited to IB (interbank) account, etc.) in the target resource management service. The accounting account includes all resource transfer records of all target accounts corresponding to the target resource management server, so that the target resource management server can know its existence according to all the resource transfer records included in the accounting account.

In the embodiment of the present application, when the blockchain system receives a resource transfer request from the first resource account to the second resource account, it transfers the tokens in the first blockchain account corresponding to the first resource account to the second resource account. In the second blockchain account corresponding to the second resource account. In this way, the resource transfer between resource accounts in different resource management servers is converted into the token transfer between different blockchain accounts in the blockchain system. On the one hand, it can speed up the processing speed of the process, improve the efficiency of resource transfer, and at the same time avoid the problem of exchange loss in related technologies. On the other hand, the immutability of the blockchain can reduce the risk of resource transfer. Once a problem occurs, it can accurately trace the source and locate the specific process point and responsible person of the problem, which is safe and reliable.
