Background

Along with the increasing closeness of global economic communication, the cross-border trade is increased, and the demand of on-line cross-border payment is also increased.

At present, banks in different countries jointly establish a block chain-based cross-border payment system, and agree to use the currency of any country as the intermediary currency. When cross-border payment is carried out, a certain bank calls a block chain intelligent contract to purchase the intermediary currency by using the currency of the country, and the intermediary currency is paid to the bank where the payee is located through the cross-border payment system. After the bank where the payee is located receives the intermediary currency, the bank where the payee is located calls the block chain intelligent contract to sell the intermediary currency to obtain the currency of the country where the bank is located, and the obtained currency is added into the account of the payee.

The system architecture according to the embodiments of the present application is described below.

Fig. 3 is a schematic diagram of a resource transfer system according to an embodiment of the present application. Referring to fig. 3, the resource transfer system includes: a plurality of resource management servers 301 and a blockchain system 302.

The blockchain system 302 may be the blockchain system 100 described above in the embodiments of fig. 1-2. Each resource management server 301 of the plurality of resource management servers 301 and the blockchain system 302 may communicate over a wired network or a wireless network. That is, each resource management server 301 of the plurality of resource management servers 301 may access the blockchain system 302.

Each resource management server 301 of the plurality of resource management servers 301 is for performing resource management. The resource may be a resource having a value of circulation, for example, the resource may be money, in which case the plurality of resource management servers 301 may be servers of respective financial institutions (e.g., banks).

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

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

The plurality of resource management servers 301 include a target resource management server 3011 and other resource management servers 3012 other than the target resource management server 3011, and the number of the other resource management servers 3012 may be greater than or equal to 2. The target resource management server 3011 may be a resource management server of a token issuer. The other resource management server 3012 may be a resource management server that is not a token issuer. In the embodiment of the present application, the target resource management server 3011 may be deployed in a region qualified for issuing tokens, another resource management server 3012 may be deployed in another region, and a different resource management server 3012 may be deployed in a different region.

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

Blockchain accounts are accounts that exist on a blockchain that blockchain system 302 configures. That is, account data for blockchain accounts is stored in blockchains configured by blockchain system 302. The account data of the blockchain account may include an account address, a balance, a state variable, and the like, where the balance of the blockchain account indicates the number of tokens (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 may execute the resource transfer method described in the embodiment of fig. 4 below to implement resource transfer between resource accounts in different resource management servers.

The resource transfer method provided in the embodiments of the present application is explained in detail below.

Fig. 4 is a flowchart of a resource transfer method according to an embodiment of the present application. Referring to fig. 4, the method includes the following steps.

The resource management server may register a corresponding blockchain account for the resource account at the blockchain system. The following description will take the first resource management server and the second resource management server as an example to describe the blockchain account registration process, which may include the following steps 401 to 404. In step 401 and step 402, the first resource management server registers a corresponding blockchain account for the first resource account in the blockchain system, and in step 403 and step 404, the second resource management server registers a corresponding blockchain account for the second resource account in the blockchain system.

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

The blockchain account registration request is used for requesting registration of a 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 a number of the first resource account. The first resource account is a resource account that the user is registered with 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 in the server of the bank by the user, and the first resource account identifier may be an account number of the bank account.

The user can initiate a block chain account registration application to the first resource management server through the first resource management client, wherein the block chain account registration application comprises a first resource account identifier and user information.

After receiving the blockchain account registration request, the first resource management server may send the blockchain account registration request to a blockchain system. Optionally, after receiving the blockchain account registration application, the first resource management server may first perform an audit on the blockchain account registration application, and after the audit is passed, send the blockchain account registration request to the blockchain system.

The first resource management server may automatically check the blockchain account registration application, for example, the first resource management server may check the blockchain account registration application according to a preset registration condition, where the registration condition may be preset according to a specific service requirement. If the block chain account registration application meets the registration condition, the first resource management server determines that the block chain account registration application is approved; if the blockchain account registration application does not meet the registration condition, the first resource management server determines that the blockchain account registration application is not approved.

Alternatively, the review of the blockchain account registration request by the first resource management server may be performed manually, for example, the review of the blockchain account registration request may be performed by a staff member of the first resource management server. When the staff determines that the block chain account registration application has no problem, an audit passing instruction can be triggered, and after the first resource management server detects the audit passing instruction, the first resource management server determines that the block chain account registration application is approved; when the staff determines that the block chain account registration application has a problem, an auditing failure instruction can be triggered, and after the first resource management server detects the auditing failure instruction, the first resource management server determines that the block chain account registration application is not approved.

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

Specifically, after receiving a blockchain account registration request sent by a first resource management server, a blockchain system may generate a first blockchain account, where account data of the first blockchain account includes an account address and a balance; and correspondingly storing the first resource account identifier carried by the block chain account registration request and the account address of the first block chain account.

After the first resource account identifier is stored in correspondence with 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 the embodiments of the present application.

Step 403: and the second resource management server sends a block chain account registration request to the block chain system, wherein the block chain account registration request carries a second resource account identifier.

The blockchain account registration request is used for requesting registration of a blockchain account corresponding to the second resource account. The second resource management server is a different resource management server than the first resource management server. Optionally, the first resource management server and the second resource management server are located in different regions. For example, the first resource management server and the second resource management server may be deployed in different organizations or countries, and 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 payment.

The second resource account identifier is used to identify the second resource account, for example, the second resource account identifier may be a number of the second resource account. The second resource account is a resource account that the user is registered with 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 in the server of the bank by the user, and the second resource account identifier may be an account number of the bank account.

The user can initiate a block chain account registration application to the second resource management server through the second resource management client, wherein the block chain account registration application comprises a second resource account identifier and user information.

After receiving the blockchain account registration application, the second resource management server may send the blockchain account registration request to the blockchain system. Optionally, after receiving the blockchain account registration application, the second resource management server may first perform an audit on the blockchain account registration application, and after the audit is passed, send the blockchain account registration request to the blockchain system.

The second resource management server may automatically check the blockchain account registration application, for example, the second resource management server may check the blockchain account registration application according to a preset registration condition, and the registration condition may be preset according to a specific service requirement. If the block chain account registration application meets the registration condition, the second resource management server determines that the block chain account registration application is approved; and if the block chain account registration application does not meet the registration condition, the second resource management server determines that the block chain account registration application is not approved.

Alternatively, the second resource management server may perform the review of the blockchain account registration request manually, for example, a worker of the second resource management server may perform the review of the blockchain account registration request. When the staff determines that the block chain account registration application has no problem, an audit passing instruction can be triggered, and after the second resource management server detects the audit passing instruction, the second resource management server determines that the block chain account registration application is approved; when the staff determines that the block chain account registration application has a problem, an auditing failure instruction can be triggered, and after the second resource management server detects the auditing failure instruction, the second resource management server determines that the block chain account registration application is not approved.

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

Specifically, after receiving a blockchain account registration request sent by a second resource management server, the blockchain system may generate a second blockchain account, where account data of the second blockchain account includes an account address and a balance; and correspondingly storing the second resource account identifier carried by the block chain account registration request and the account address of the second block chain account.

After the second resource account identifier is stored in correspondence with the account address of the second blockchain account, the second resource account is bound to the second blockchain account.

The operation of generating the second 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 the embodiments 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 may also set the balance of the blockchain account corresponding to the resource account according to the resource transfer condition between the resource account and the corresponding target account. The resource account is a first resource account or a second resource account.

The resource account and the corresponding target account are registered in the same resource management server. The resource account is obtained by registering a user in a resource management server, and the target account corresponding to the resource account is obtained by registering a target resource management server in the resource management server. All resource accounts in one resource management server correspond to one target account in the resource management server, that is, the target account corresponding to a certain resource account is the target account in the resource management server to which the resource account belongs. Resource transfer can be directly carried out between the resource account and the target account which belong to the same resource management server. For example, transfers may be made directly between multiple bank accounts belonging to the same bank's server.

In a possible case, the operation of setting the balance of the blockchain account corresponding to the resource account by the blockchain system according to the resource transfer condition between the resource account and the corresponding target account may be an operation of charging the blockchain account by the user to which the resource account belongs through the resource account. Recharging the blockchain account stores tokens in the blockchain account.

Taking the example that the user to which the first resource account belongs charges the corresponding blockchain account through the first resource account as an example, the specific process may include the following steps 405 to 407. The process of recharging the corresponding blockchain account by the user to which the second resource account belongs through the second resource account is similar, and details of this embodiment are not repeated.

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

The token storage request carries a second amount of resources to be stored by the first resource account. In particular, the token store request may include a first resource account identification and a second resource amount.

The user can initiate a token storage application to the first resource management server through the first resource management client, wherein the token storage application comprises a first resource account identifier, user information and a second resource quantity to be stored.

The first resource management server may send the token storage request to the blockchain system after receiving the token storage request. Optionally, after receiving the token storage application, the first resource management server may perform an audit on the token storage application, and send the token storage request to the block chain system after the audit is passed.

The checking of the token storage application by the first resource management server may be performed automatically, for example, the first resource management server may check the token storage application according to a preset storage condition, and the storage condition may be preset according to a specific business requirement. If the token storage application meets the storage condition, the first resource management server determines that the token storage application passes the verification; if the token storage application does not meet the storage condition, the first resource management server determines that the token storage application is not approved.

Alternatively, the audit of the token storage application by the first resource management server may be performed manually, for example, the audit of the token storage application may be performed by a staff member of the first resource management server. When the staff determines that the token storage application has no problem, an audit passing instruction can be triggered, and after the first resource management server detects the audit passing instruction, the first resource management server determines that the token storage application is approved; when the staff determines that the token storage application has a problem, an auditing failure instruction can be triggered, and after the first resource management server detects the auditing failure instruction, the staff determines that the token storage application auditing failure occurs.

Step 406: and after receiving the token storage request sent by the first resource management server, the block chain system transfers the resources with the second resource quantity in the first resource account to the target account corresponding to the first resource account.

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

Specifically, after receiving a token storage request sent by a first resource management server, a block chain system calls a resource transfer interface provided by the first resource management server according to a first resource account identifier, a second resource amount and a target account identifier corresponding to the first resource management server carried in the token storage request, so as to transfer the resource of the second resource amount in the first resource account to the target account in the first resource management server, that is, to transfer the resource to the target account corresponding to the first resource account.

Each resource management server has a target account registered therein. The blockchain system may pre-store the target account id 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 a 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: and the blockchain system determines the number of second coins corresponding to the second resource quantity, and transfers the tokens of the second coins in the balance of the target blockchain account into the balance of the first blockchain account.

In this case, the token in the target blockchain account is transferred to the first blockchain account.

There may be a conversion rate between the number of resources and the number of tokens, for example a conversion rate that may be set to 1:1, in which case the number of resources and the number of tokens are the same. Of course, other conversion rates may also be set, and the setting may be specifically performed according to business requirements, which is not limited in this application embodiment.

After receiving a token storage request sent by a first resource management server, the block chain system may determine an account address corresponding to a first resource account identifier carried in the token storage request, and use a block chain account to which the acquired account address belongs as a first block chain account corresponding to the first resource account.

The operation of transferring the tokens of the second token number in the balance of the target blockchain account to the balance of the first blockchain account by the blockchain system is to reduce the tokens of the second token number in the balance of the target blockchain account and increase the tokens of the second token number in the balance of the first blockchain account.

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

In this embodiment, the block chain system may transfer the resource in the first resource account to a target account in a resource management server that belongs to the same resource account as the first resource account, and then transfer the token in the target block chain account to the first block chain account corresponding to the first resource account. Therefore, the effect of using the resources in the first resource account and storing the token in the first block chain account corresponding to the first resource account is achieved, and the recharging of the first block chain account is realized.

Further, after the user to which the resource account belongs recharges the blockchain account corresponding to the resource account through the resource account, the balance in the blockchain account can be used for resource transfer operation.

Taking the example of transferring resources from the first resource account to the second resource account as an example, the specific process may include the following steps 408 to 409. The process of transferring resources from the second resource account to the first resource account is similar, and details of this embodiment are not repeated.

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

The resource transfer request is used to request a resource transfer. The resource transfer request carries a first resource amount that the first resource account needs to transfer to the second resource account. Specifically, the resource transfer request may carry a resource account identifier of the payer (i.e., a first resource account identifier), a resource account identifier of the payee (i.e., a second resource account identifier), and a 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, wherein the resource transfer application comprises a first resource account identifier, a 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 first perform an audit on the resource transfer application, and after the audit is passed, send the resource transfer request to the blockchain system.

The first resource management server may automatically check the resource transfer application, for example, the first resource management server may check the resource transfer application according to a preset transfer condition, and the transfer condition may be preset according to a specific service requirement. If the resource transfer application meets the transfer condition, the first resource management server determines that the resource transfer application is approved; and 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 auditing of the resource transfer application by the first resource management server may be performed manually, for example, the auditing of the resource transfer application may be performed by a worker of the first resource management server. When the staff determines that the resource transfer application has no problem, an audit passing instruction can be triggered, and after the first resource management server detects the audit passing instruction, the first resource management server determines that the resource transfer application is approved; when the staff determines that the resource transfer application has a problem, an auditing failure instruction can be triggered, and after the first resource management server detects the auditing failure instruction, the first resource management server determines that the resource transfer application auditing failure.

Step 409: after receiving a resource transfer request sent by a first resource management server, the block chain system determines the number of first coins corresponding to the first resource number, and transfers the tokens of the first coin number in the balance of the first block chain account to the balance of a second block chain account.

After receiving the resource transfer request sent by the first resource management server, the blockchain system may determine an account address corresponding to the first resource account identifier carried in the resource transfer request, and use the blockchain account to which the acquired account address belongs as the first blockchain account corresponding to the first resource account. And the blockchain system can determine an account address corresponding to the second resource account identifier carried by the resource transfer request, and take the blockchain account to which the acquired account address belongs as the second blockchain account corresponding to the second resource account.

The operation of transferring the tokens of the first number of the tokens in the balance of the first blockchain account to the balance of the second blockchain account by the blockchain system is to reduce the tokens of the first number of the tokens in the balance of the first blockchain account and increase the tokens of the first number of the tokens in the balance of the second blockchain account.

Furthermore, after the block chain system receives the resource transfer request sent by the first resource management server, before determining the number of the first coins corresponding to the first resource quantity and transferring the tokens of the first coin number in the balance of the first block chain account to the balance of the second block chain account, the block chain system may also check the resource transfer request; after the resource transfer request is checked, determining the number of first coins corresponding to the first resource number, and transferring the tokens with the number of the first coins in the balance of the first block chain account into the balance of the second block chain account; and ending the operation after the resource transfer request is not approved.

For example, when the blockchain system performs an audit on the resource transfer request, the state of the resource transfer request may be set to be audited, and the resource transfer request may be stored in the database. Then, the blockchain system may store the resource transfer request to a blockchain configured by the blockchain system, and after obtaining an uplink transaction execution result, send the resource transfer request to an operation server, where the operation server performs an audit on the resource transfer request. After the resource transfer request is approved by the operation server, the state of the resource transfer request can be modified to be approved, and then the resource transfer request is sent to the block chain system. After receiving the resource transfer request, the blockchain system may modify the status of the resource transfer request stored in the database to be checked.

When the block chain system sends the resource transfer request to the operation server, the resource transfer request may be sent to the operation server through MQ (Message Queuing) Message middleware. Of course, the blockchain system may also send the resource transfer request to the operation server in other manners, which is not limited in this embodiment of the present application.

The operation server may be a server of a third party regulatory agency, and may be responsible for auditing resource transfer between resource accounts in different resource management servers to determine that resource transfer between resource accounts in different resource management servers is normal and safe.

When the operation server audits the resource transfer request, the operation server can perform primary audit on the resource transfer request by staff of the operation server, after the primary audit is passed, the operation server can send the resource transfer request to the second resource management server, the second resource management server performs secondary audit on the resource transfer request, and after the secondary audit is passed, the operation server can determine that the resource transfer request is approved.

For example, when the blockchain system transfers the tokens of the first number of tokens in the balance of the first blockchain account to the balance of the second blockchain account, it may be determined whether the resource transfer request has been processed before, and 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 may be transferred to the balance of the second blockchain account. Then, if the token of the first number of tokens in the balance of the first blockchain account is successfully transferred to the balance of the second blockchain account, the blockchain system may modify the status of the resource transfer request to be processing completion.

If the transfer of the tokens of the first number of coins in the balance of the first blockchain account to the balance of the second blockchain account is not successful, the blockchain system may determine a transaction failure reason (e.g., transaction timeout), and retry the transfer of the tokens of the first number of coins in the balance of the first blockchain account to the balance of the second blockchain account according to the transaction failure reason.

In the embodiment of the present application, when receiving a resource transfer request from a first resource account to a second resource account, a blockchain system transfers a token in the first blockchain account corresponding to the first resource account to the second blockchain account corresponding to the second resource account. As such, the resource transfer between resource accounts in different resource management servers is translated to a token transfer between different blockchain accounts in a blockchain system. On one hand, the method can accelerate the process processing speed, improve the resource transfer efficiency and simultaneously avoid the exchange loss problem in the related technology. On the other hand, the non-tamper property of the block chain can reduce the resource transfer risk, once a problem occurs, the tracing can be accurately tracked, the specific process point and responsible person of the problem can be positioned, and the method is safe and reliable.

In a possible case, the operation of setting the balance of the blockchain account corresponding to the resource account by the blockchain system according to the resource transfer condition between the resource account and the corresponding target account may be an operation of bringing up the user to which the resource account belongs from the blockchain account to the resource account. The withdrawal to the resource account is the transfer of the resource to the resource account.

Taking the example that the user to which the second resource account belongs withdraws from the blockchain account corresponding to the second resource account, the specific process may include the following steps 410 to 412. The process of presenting the user to which the first resource account belongs from the blockchain account corresponding to the first resource account is similar, and details of the process are not repeated in this embodiment of the application.

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

The resource extraction request carries a third resource quantity to be extracted by the second resource account. In particular, the resource extraction request may include a second resource account identification 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, wherein the resource extraction application comprises a second resource account identifier, user information and the number of third resources to be extracted.

The second resource management server may send the resource extraction request to the blockchain system after receiving the resource extraction request. Optionally, after receiving the resource extraction application, the second resource management server may first perform an audit on the resource extraction application, and after the audit is passed, send the resource extraction request to the block chain system.

The second resource management server may automatically check the resource extraction application, for example, the second resource management server may check the resource extraction application according to a preset extraction condition, and the extraction condition may be preset according to a specific service requirement. If the resource extraction application meets the extraction condition, the second resource management server determines that the resource extraction application is approved; and if the resource extraction application does not meet the extraction condition, the second resource management server determines that the resource extraction application is not approved.

Alternatively, the second resource management server may perform the review of the resource extraction application manually, for example, the second resource management server may perform the review of the resource extraction application by a worker. When the staff determines that the resource extraction application has no problem, an audit passing instruction can be triggered, and after the second resource management server detects the audit passing instruction, the second resource management server determines that the resource extraction application is approved; when the staff determines that the resource extraction application has a problem, an auditing failure instruction can be triggered, and after the second resource management server detects the auditing failure instruction, the staff determines that the resource extraction application auditing failure occurs.

Step 411: and after receiving the resource extraction request sent by the second resource management server, the block chain system determines the number of third coins corresponding to the third resource quantity, and transfers the tokens of the third coins in the balance of the second block chain account to the balance of the target block chain account.

In this case, the token in the second blockchain account is transferred to the target blockchain account.

After receiving the resource extraction request sent by the second resource management server, the blockchain system may determine an account address corresponding to a second resource account identifier carried in the resource extraction request, and use a blockchain account to which the acquired account address belongs as a second blockchain account corresponding to the second resource account.

The operation of transferring the tokens of the third generation of coins in the balance of the second block chain account to the balance of the target block chain account by the block chain system is to reduce the tokens of the third generation of coins in the balance of the third block chain account and increase the tokens of the second generation of coins in the balance of the target block chain account.

Step 412: and the block chain system transfers the resources of the third resource quantity in the target account corresponding to the second resource account.

In this case, the resource in the target account belonging to the same resource management server as the second resource account is transferred to the second resource account.

Specifically, the block chain system calls a resource transfer interface provided by the second resource management server according to the target account identifier corresponding to the second resource management server, the second resource account identifier carried in the resource extraction request, and the third resource quantity, so as to transfer the target account in the second resource management server, that is, the resource of the third resource quantity in the target account corresponding to the second resource account.

In this embodiment, the blockchain system may transfer the token in the second blockchain account to the target blockchain account, and then transfer the resource in the target account in the resource management server that belongs to the same resource account as the second resource account to the second resource account. Therefore, the effect of extracting the token in the second block chain account corresponding to the second resource account as the resource in the second resource account is achieved, namely the cash withdrawal to the second resource account is realized.

Further, since the target account is a resource account registered by the target resource management server in each of the other resource management servers, that is, the target resource management server is a resource management server to which the target account belongs, in this embodiment of the application, the resource transfer record related to the target account may also be notified to the target resource management server, so that the target resource management server can perform subsequent reconciliation conveniently. Specifically, steps 413 to 414 may be included as follows.

Step 413: and the block chain system generates a target account resource transfer record according to the resource transfer condition between the resource account and the corresponding target account.

The target account resource transfer record is used for recording the resource transfer-out condition and the resource transfer-in condition in the target account. For example, the target account resource transfer record may record the above-mentioned situation of transferring the resource in the first resource account to the target account, or the target account resource transfer record may record the above-mentioned situation of transferring the resource in the target account to the second resource account. When the target account has resource transfer (including resource transfer-out or resource transfer-in) once, the block chain system can generate a target account resource transfer record according to the current resource transfer condition of the target account.

Step 414: and the block chain system sends the target account resource transfer record to the target resource management server.

Specifically, the blockchain system may send the target account resource transfer records to accounting accounts (including but not limited to ib (internbank) accounts, etc.) in the target resource management service. The accounting account comprises all resource transfer records of all target accounts corresponding to the target resource management server, so that the target resource management server can know the resource transfer records in the accounting account according to all resource transfer records in the accounting account.

In this embodiment, when receiving a resource transfer request from a first resource account to a second resource account, the blockchain system transfers a token in the first blockchain account corresponding to the first resource account to the second blockchain account corresponding to the second resource account. As such, the resource transfer between resource accounts in different resource management servers is translated to a token transfer between different blockchain accounts in a blockchain system. On one hand, the method can accelerate the process processing speed, improve the resource transfer efficiency and simultaneously avoid the exchange loss problem in the related technology. On the other hand, the non-tamper property of the block chain can reduce the resource transfer risk, once a problem occurs, the tracing can be accurately tracked, the specific process point and responsible person of the problem can be positioned, and the method is safe and reliable.
