Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with one or more embodiments of the present specification. Rather, they are merely examples of apparatus and methods consistent with certain aspects of one or more embodiments of the specification, as detailed in the claims which follow.

It should be noted that: in other embodiments, the steps of the corresponding methods are not necessarily performed in the order shown and described herein. In some other embodiments, the method may include more or fewer steps than those described herein. Moreover, a single step described in this specification may be broken down into multiple steps for description in other embodiments; multiple steps described in this specification may be combined into a single step in other embodiments.

Cross-border resource transfer refers to providing resource transfer from one member's national border to another member's national border. The initiator and the receiver of the cross-border resource transfer are respectively positioned in different countries, and in the process of providing the cross-border resource transfer service, the service content per se crosses the national border, and the cross-border resource transfer can be realized through the networking of telecommunication and computers without the flow of personnel, materials and capital.

For example, in practical applications, a cross-border resource transfer may include a cross-border reservation remittance; the cross-border reservation remittance refers to that cross-country reservation students settle the reservation charges to the reservation and reading school through a cross-border remittance organization, so that cross-border transfer of the charges is completed.

In general, the existing process of cross-border reservation remittance can include data auditing and remittance settlement, and at present, the data auditing is mainly completed by entrusting a third party organization by a reservation remittance service provider (such as a school for students to read), which has the following problems:

problem 1: for the collection remittance service provider, each collection remittance needs to pay a verification fee to the third-party organization, the third-party organization has misjudgment, and customer complaints and fund loss caused by the misjudgment need to be borne by the collection remittance service provider.

Problem 2: for remittance users who are left to school, the third-party organization usually adopts a manual auditing mode, and the auditing period is too long, so that the users can not pay the fees in time, and the entrance is delayed.

Problem 3: for schools, the accuracy of payment information cannot be guaranteed by a third party institution alone, and usually the most authoritative payment information comes from the school, but the school party does not participate in cross-border reservation remittance audit.

In order to solve the above problems, the present specification aims to provide a technical solution for cross-border resource transfer authenticity audit based on a block chain and an intelligent contract.

When the cross-border resource transfer is realized, the cross-border resource transfer initiator, the cross-border resource transfer receiver and the cross-border resource transfer auditor are used as block chain members to be accessed into a block chain comprising a plurality of node devices.

Further, the node equipment in the block chain receives a first target transaction initiated by the cross-border resource transfer auditor; the first target transaction comprises resource transfer information initiated by a cross-border resource transfer initiator; and a trusted credential corresponding to the resource transfer information provided by the cross-border resource transfer recipient to the cross-border resource transfer initiator; the trusted voucher is an electronic voucher generated based on the certification information stored in the block chain.

And further, responding to the first target transaction, invoking a trusted certificate checking logic in an intelligent contract which is deployed on the block chain and used for verifying the authenticity of the resource transfer information, and verifying whether the trusted certificate is a trusted certificate generated based on the certification information which is stored in the block chain and corresponds to the resource transfer information.

Further, if yes, the authenticity verification of the resource transfer information is determined to be passed, and an authenticity verification result of the resource transfer information is returned to the cross-border resource transfer auditor.

Referring to fig. 1, fig. 1 is a flowchart of a cross-border resource transfer authenticity auditing method according to an exemplary embodiment, where the method is applied to a resource transfer management system built based on a block chain; the method specifically comprises the following steps:

102, receiving a first target transaction initiated by a cross-border resource transfer auditor; the first target transaction comprises resource transfer information initiated by a cross-border resource transfer initiator; and a trusted credential corresponding to the resource transfer information provided by the cross-border resource transfer recipient to the cross-border resource transfer initiator; the trusted voucher is an electronic voucher generated based on the certification information stored in the block chain.

And 104, responding to the first target transaction, calling a trusted certificate checking logic in an intelligent contract which is deployed on the block chain and used for verifying the authenticity of the resource transfer information, and verifying whether the trusted certificate is a trusted certificate generated based on the certification information which is stored in the block chain and corresponds to the resource transfer information.

And 106, if so, determining that the authenticity verification of the resource transfer information is passed, and returning an authenticity verification result of the resource transfer information to the cross-border resource transfer auditing party.

In this specification, the cross-border resource transfer includes any resource type cross-border resource transfer.

For example, in practical applications, the cross-border resource transfer may include a cross-border virtual resource transfer and a cross-border physical resource transfer. Wherein the cross-border virtual resources may include virtual tokens (bitcoin, etherhouse coin, etc.), points, stocks, etc.; the cross-border entity resource transfer may include cross-border remittance, etc.

In one illustrated embodiment, the cross-border resource transfer is a cross-border reservation remittance. Of course, in practical applications, the cross-border resource transfer may also include cross-border resource transfers of other service types.

In this specification, the cross-border resource transfer initiator may include a unit or an individual who initiates the cross-border resource transfer.

For example, in a cross-border reservation remittance scenario, the cross-border resource transfer initiator may be a reservation user for cross-border reservation remittance, and the reservation user may conduct a cross-border reservation remittance to a reservation organization through an on-hold client.

In this specification, the cross-border resource transfer recipient refers to a provider that provides an offline service corresponding to the cross-border resource transfer initiator online.

Taking the cross-border resource transfer as a cross-border reservation remittance and the cross-border resource transfer initiator as a cross-border reservation user as an example, the cross-border resource transfer receiver may provide a reservation organization corresponding to the cross-border reservation remittance for the cross-border reservation user on line, such as: a school for the study-keeping user to read or an intermediary organization for providing the study-keeping user with the study-keeping and reading, etc.

In this specification, the cross-border resource transfer auditor refers to an auditor for auditing the authenticity of the cross-border resource transfer in the cross-border resource transfer service performed by the cross-border resource transfer initiator to the cross-border resource transfer receiver;

the cross-border resource transfer auditor can comprise a cross-border resource transfer accepting party; or the cross-border resource transfer supervisor is in butt joint with the cross-border resource transfer party.

For example, in a cross-border reservation remittance scenario, the cross-border resource transfer acceptor may be any one or a combination of a paymate server, an domestic banking institution, an overseas banking institution and the like that provide the cross-border reservation remittance to the cross-border resource transfer recipient, and the cross-border resource transfer supervisor may specifically include a overseas and overseas supervisory institution and the like.

In this specification, the cross-border resource transfer initiator, the cross-border resource transfer receiver, and the cross-border resource transfer auditor may be accessed as members of a block chain to the block chain including a plurality of node devices; the block chain may specifically include any type of block chain network.

In an embodiment shown in the present disclosure, the blockchain is a federation chain, and the cross-border resource transfer initiator, the cross-border resource transfer receiver, and the cross-border resource transfer auditor may be added to the blockchain as member devices of the federation chain.

Taking the cross-border resource transfer as a cross-border study remittance as an example, the cross-border resource transfer initiator is a treasury client held by a study-reserving user, the cross-border resource transfer receiver is a school server of a school providing study-reserving and reading for the study-reserving user, and the cross-border resource transfer auditor is a treasury service end used for the study-reserving user to perform study-reserving remittance to the school through the treasury client and is added to the blockchain as a member device of the alliance chain.

Of course, in practical applications, besides that the cross-border resource transfer receiver may be directly added to the block chain as a member device of a federation chain, the cross-border resource transfer initiator may also be accessed to the cross-border resource transfer auditor through a client, and the cross-border resource transfer auditor may be directly added to the block chain as a member device of the federation chain.

Taking the cross-border resource transfer as the cross-border reservation remittance as an example, the cross-border resource transfer initiator may also access the paymate server through the paymate client, and the paymate server may be added to the blockchain as a member device of the alliance chain.

For ease of understanding, the underlying concepts related to the lower blockchain are briefly introduced here.

Blockchains are generally divided into three types: public chain (Public Blockchain), private chain (PrivateBlockchain) and alliance chain (Consortium Blockchain). Furthermore, there may be a combination of the above types, such as private chain + federation chain, federation chain + public chain, and so on.

Among them, the most decentralized is the public chain. The public chain is represented by bitcoin and ether house, and participants (also called nodes in the block chain) joining the public chain can read data records on the chain, participate in transactions, compete for accounting rights of new blocks, and the like. Moreover, each node can freely join or leave the network and perform related operations.

Private chains are the opposite, with the network's write rights controlled by an organization or organization and the data read rights specified by the organization. Briefly, a private chain may be a weakly centralized system with strict restrictions on nodes and a small number of nodes. This type of blockchain is more suitable for use within a particular establishment.

A federation chain is a block chain between a public chain and a private chain, and "partial decentralization" can be achieved. Each node in a federation chain typically has a physical organization or organization corresponding to it; the nodes are authorized to join the network and form a benefit-related alliance, and block chain operation is maintained together.

Based on the basic characteristics of a blockchain, a blockchain is usually composed of several blocks. The time stamps corresponding to the creation time of the block are recorded in the blocks respectively, and all the blocks form a time-ordered data chain according to the time stamps recorded in the blocks strictly.

The real data generated by the physical world can be constructed into a standard transaction (transaction) format supported by a block chain, then is issued to the block chain, the node equipment in the block chain performs consensus processing on the received transaction, and after the consensus is achieved, the node equipment serving as an accounting node in the block chain packs the transaction into a block and performs persistent evidence storage in the block chain.

The consensus algorithm supported in the blockchain may include:

the first kind of consensus algorithm, namely the consensus algorithm that the node device needs to contend for the accounting right of each round of accounting period; consensus algorithms such as Proof of Work (POW), Proof of equity (POS), Proof of commission rights (DPOS), etc.;

the second kind of consensus algorithm, namely the consensus algorithm which elects accounting nodes in advance for each accounting period (without competing for accounting right); for example, a consensus algorithm such as a Practical Byzantine Fault Tolerance (PBFT) is used.

In a blockchain network employing a first type of consensus algorithm, node devices competing for billing rights can execute a transaction upon receipt. One of the node devices competing for the accounting right may win in the process of competing for the accounting right in the current round, and become an accounting node. The accounting node may package the received transaction with other transactions to generate a latest block and send the generated latest block or a block header of the latest block to other node devices for consensus.

In the block chain network adopting the second type of consensus algorithm, the node equipment with the accounting right is agreed before accounting in the current round. Thus, the node device, after receiving the transaction, may send the transaction to the accounting node if it is not the accounting node of its own round. For the accounting node of the current round, the transaction may be performed during or before packaging the transaction with other transactions to generate the latest block. After generating the latest block, the accounting node may send the latest block or a block header of the latest block to other node devices for consensus.

As described above, regardless of which consensus algorithm is used by the blockchain, the accounting node of the current round may pack the received transaction to generate the latest block, and send the generated latest block or the block header of the latest block to other node devices for consensus verification. If no problem is verified after other node equipment receives the latest block or the block header of the latest block, the latest block can be added to the tail of the original block chain, so that the accounting process of the block chain is completed. The transaction contained in the block may also be performed by other nodes in verifying the new block or block header sent by the accounting node.

In this specification, the certification information refers to any form of certification data issued by the cross-border resource transfer recipient and used for certifying the authenticity of the cross-border resource transfer information, which is stored in the blockchain.

In an embodiment shown, the cross-border resource transfer certification information may be a chargeback payment certification information provided by a school party providing a chargeback reading for the chargeback user for performing a chargeback remittance;

the information of paying for leaving school at least includes the identification information of the school party and the user, and the data of paying for leaving school by the user. For example, the information of the leave-behind payment certification may specifically include a name of a school owner, information of a collection account, information of an identity of a leave-behind user, a leave-behind fee to be paid by the leave-behind user, and the like.

Of course, in practical applications, the information on the leave-behind payment certification may also include other KYC (knock money customer) information, a leave-behind remittance amount, and the like of the school party and the leave-behind user, and is not limited in this specification. It should be noted that the cross-border resource transfer certification information may be used to certify that the remittance relationship between the remitter (the cross-border resource transfer initiator) and the recipient (the cross-border resource transfer recipient) is authentic.

In this specification, a node device in the blockchain receives a second target transaction initiated by the cross-border resource transfer recipient; wherein the second target transaction includes the certification information provided by the cross-border resource transfer recipient;

taking the cross-border resource transfer as a cross-border reservation remittance as an example, the node equipment in the block chain receives a target transaction initiated by a school party who reserves the study and reads by a reservation user; the target transaction comprises the information of the payment for the reservation of the reservation for the reservation user to perform the money transfer for the reservation.

In this specification, the intelligent contract refers to an intelligent contract deployed in the blockchain and used for verifying the authenticity of the cross-border resource transfer.

For ease of understanding, the underlying concepts related to the intelligent contracts are briefly introduced here.

In practical applications, whether public, private, or alliance, it is possible to provide the functionality of a smart contract (Smartcontract). An intelligent contract on a blockchain is a contract on a blockchain that can be executed triggered by a transaction. An intelligent contract may be defined in the form of code.

Taking an Etherhouse as an example, a user is supported to create and call some complex logic in the Etherhouse network. The ethernet workshop is used as a programmable block chain, and the core of the ethernet workshop is an ethernet workshop virtual machine (EVM), and each ethernet workshop node can run the EVM. The EVM is a well-behaved virtual machine through which various complex logic can be implemented. The user issuing and invoking smart contracts in the etherhouse is running on the EVM. In fact, the EVM directly runs virtual machine code (virtual machine bytecode, hereinafter referred to as "bytecode"), so the intelligent contract deployed on the blockchain may be bytecode. After the EtherFang nodes reach the agreement through the consensus mechanism, the intelligent contract is successfully created, and the follow-up user can call the intelligent contract.

After the intelligent contract is created, a contract account corresponding to the intelligent contract appears on the blockchain and has a specific address. The contract Code (Code) and account store (Storage) will be maintained in the account store for that contract account. The behavior of the intelligent contract is controlled by the contract code, while the account storage of the intelligent contract preserves the state of the contract. In other words, the intelligent contract causes a virtual account to be generated on the blockchain that contains the contract code and account storage.

When developing an intelligent contract, a developer may select a high-level language for writing intelligent contract code. For example, the high-level language may employ a language such as Solidity, Serpent, LLL, and the like. For intelligent contract code written in a high-level language, the intelligent contract code can be compiled by a compiler to generate byte codes which can be deployed on a blockchain.

Taking the Solidity language as an example, the contract code written by it is very similar to a Class (Class) in the object-oriented programming language, and various members including state variables, functions, function modifiers, events, etc. can be declared in one contract. A state variable is a value permanently stored in an account Storage (Storage) field of an intelligent contract to save the state of the contract.

The intelligent contract can be independently executed at each node in the blockchain network in a specified mode, and all execution records and data are stored on the blockchain, so that after the transaction is executed, transaction certificates which cannot be tampered and lost are stored on the blockchain.

An intelligent contract is created in an Ethernet workshop and needs to be subjected to the processes of compiling the intelligent contract, changing the intelligent contract into byte codes, deploying the intelligent contract to a block chain and the like. The intelligent contract is called in the Ethernet workshop, a transaction pointing to the intelligent contract address is initiated, the EVM of each node can respectively execute the transaction, and the intelligent contract code is distributed and operated in the virtual machine of each node in the Ethernet workshop network.

Intelligent contracts deployed on blockchains can generally only refer to data contents stored on blockchains; in practical applications, for some complex business scenarios implemented based on the intelligent contract technology, the intelligent contract may need to refer to some external data on the data entities outside the chain.

The event mechanism of the intelligent contract is a mode for the interaction between the intelligent contract and the out-of-chain entity. For intelligent contracts deployed on blockchains, direct interaction with out-of-chain entities is generally not possible; for example, the intelligent contract cannot generally send the call result of the intelligent contract to the call initiator of the intelligent contract point to point after the call is completed.

The call results (including intermediate results and final call results) generated during the call of the intelligent contract are usually recorded in the form of events (events) to the transaction log (transactions logs) of the transaction that called the intelligent contract, and stored in the memory space of the node device. The entity outside the chain which needs to interact with the intelligent contract can acquire the calling result of the intelligent contract by monitoring the transaction log stored in the storage space of the node equipment;

for example, in the case of an Etherhouse, the transaction log will eventually be stored in the MPT receipt tree described above as part of the receipt (receipt) of the transaction pen transaction that invoked the smart contract. And the entity outside the chain interacting with the intelligent contract can monitor the transaction receipts stored in the storage space of the node device on the MPT receipt tree and acquire the events generated by the intelligent contract from the monitored transaction receipts.

In this specification, further, in response to the second target transaction, the node device in the block chain invokes a trusted credential generation logic in the intelligent contract to generate a trusted credential corresponding to the cross-border resource transfer certification information; wherein; the trusted voucher is an electronic voucher generated based on the certification information stored in the block chain.

For example, in practical applications, the node device in the blockchain may invoke a trusted credential generation logic in the intelligent contract, and generate a corresponding trusted credential based on the certification information stored in the blockchain; the trusted certificate is an electronic certificate generated based on the certification information stored in the block chain, and the electronic certificate may specifically be a Hash value generated based on a Hash algorithm and corresponding to the certification information.

In this specification, the node device in the block chain issues the certification information and the corresponding trusted voucher to the block chain for storage.

In one embodiment, in the process of issuing the certification information and the corresponding trusted voucher to the block chain for Storage, the node device in the block chain may store the certification information and the corresponding trusted voucher in an account Storage space (for example, in a Storage tree or a receipt tree of a contract account) of a corresponding contract account of the intelligent contract in the block chain.

In one embodiment, after storing the trusted voucher in the blockchain, the node device in the blockchain acquires the trusted voucher from the blockchain in response to an acquisition request for the trusted voucher, which is initiated by the cross-border resource transfer recipient, and initiates the trusted voucher to the cross-border resource transfer recipient, so that the cross-border resource transfer recipient provides the trusted voucher to the cross-border resource transfer initiator for initiating the cross-border resource transfer by the cross-border resource transfer initiator.

For example, in practical applications, in response to an acquisition request for the trusted credential initiated by the cross-border resource transfer recipient, the node device in the blockchain acquires the certified trusted credential from a block of the blockchain or from a Storage tree of a contract account of the intelligent contract and initiates the certified trusted credential to the cross-border resource transfer recipient, so that the cross-border resource transfer recipient provides the trusted credential to the cross-border resource transfer initiator to initiate a cross-border resource transfer.

In this specification, the cross-border resource transfer recipient may provide the trusted credential to the cross-border resource transfer initiator to initiate a cross-border resource transfer.

For example, in practical applications, the cross-border resource transfer recipient provides the trusted credential to the cross-border resource transfer initiator in a manner outside the blockchain, such as email, FTP, or USB dongle, to initiate the cross-border resource transfer.

Certainly, in an actual application, the cross-border resource transfer initiator may also obtain the trusted credential by monitoring a state database of the intelligent contract or reading a block chain of the trusted credential in a Storage tree of the contract account.

In this specification, after the certification information and the trusted voucher are stored in the blockchain, a node device in the blockchain receives a first target transaction initiated by the cross-border resource transfer initiator; wherein the first target transaction comprises resource transfer information initiated by the cross-border resource transfer initiator; and the cross-border resource transfer receiver provides the cross-border resource transfer initiator with the credible certificate corresponding to the resource transfer information.

Taking the cross-border resource transfer as a cross-border reservation remittance as an example, the node device in the block chain receives a first target transaction initiated by a payer server; wherein the first target transaction comprises a reservation remittance message initiated by a reservation user; and, a trusted voucher corresponding to the reservation remittance information provided by the reservation authority to the reservation user.

It should be noted that, during the data transmission, transmission and data storage process, the trusted credential provided by the cross-border resource transfer recipient to the cross-border resource transfer initiator and corresponding to the resource transfer information may have a data transmission error or data mismatch, or a data transmission damage, a data reading error caused by a storage medium, or a data malicious tampering or forgery.

In this specification, the node device in the block chain, in response to the first target transaction, invokes a trusted credential check logic in an intelligent contract, which is deployed on the block chain and used for performing authenticity verification on the resource transfer information, to verify whether the trusted credential is a trusted credential generated based on the attestation information corresponding to the resource transfer information stored in the block chain.

Taking the example of the cross-border resource transfer as cross-border reservation remittance, the node device in the blockchain invokes a trusted voucher verification logic in an intelligent contract for verifying the authenticity of reservation remittance information, which is deployed on the blockchain, in response to the first target transaction, to verify whether the trusted voucher in the first target transaction is a trusted voucher generated based on the certification information corresponding to the reservation remittance information stored in the blockchain.

In an embodiment shown, the certification information may include user identity information corresponding to the cross-border resource transfer initiator;

wherein the user identity information comprises any data that can uniquely indicate the user identity of the cross-border resource transfer initiator. For example, the user identity information may specifically include an identity card number, a passport number, a mobile phone number, and the like of the cross-border resource transfer initiator.

In this specification, further, the node device in the blockchain may query, based on the user identity information of the cross-border resource transfer initiator in the first target transaction, the certification information stored in the blockchain and corresponding to the resource transfer information.

Taking the cross-border resource transfer as the cross-border reservation remittance as an example, the node device in the blockchain may query the certification information corresponding to the reservation remittance information stored in the blockchain based on the user identity information of the reservation user in the first target transaction.

In this specification, further, a node device in the blockchain may invoke a trusted credential generation logic in an intelligent contract deployed on the blockchain for verifying the authenticity of the resource transfer information, and generate a trusted credential based on the queried attestation information.

Continuing the example above, a node device in the blockchain may invoke trust credential generation logic in an intelligent contract deployed on the blockchain for verifying authenticity of the lien remittance information, and generate a corresponding trust credential locally at the device based on the queried attestation information of the lien remittance.

In this specification, further, after generating the trusted voucher, the node device in the blockchain may further invoke trusted voucher check logic in an intelligent contract deployed on the blockchain and used for performing authenticity verification on the resource transfer information, to verify whether the generated trusted voucher matches the trusted voucher in the first target transaction; if yes, determining that the trusted certificate in the first target transaction is a trusted certificate generated based on the certification information stored in the block chain and corresponding to the resource transfer information.

Continuing the example from the above example, after the node device in the blockchain generates the trusted voucher a based on the certification information corresponding to the reservation remittance information stored in the blockchain, the node device in the blockchain verifies whether the generated trusted voucher a matches the trusted voucher B in the first target transaction (the trusted voucher corresponding to the resource transfer information provided by the cross-border resource transfer recipient to the cross-border resource transfer initiator); if the value of the trusted voucher a is the same as that of the trusted voucher B, the trusted voucher B in the first target transaction is a trusted voucher generated based on the certification information stored in the block chain and corresponding to the study-leaving remittance information, that is, the trusted voucher B in the first target transaction is trusted. If the value of the trusted credential A is different from the value of the trusted credential B, the trusted credential B in the first target transaction is not trusted.

In this specification, when the authenticity verification of the resource transfer information in the first target transaction is passed, the node device in the block chain may return an authenticity verification result for the resource transfer information to the cross-border resource transfer auditor.

Continuing the example above, after the authenticity verification for the trusted voucher B in the first target transaction passes, the node device in the block chain may return an authenticity verification result for the cross-border reservation remittance information to the payer server (for example, the trusted voucher B in the first target transaction is trusted or untrusted).

Of course, when the authenticity verification result of the resource transfer information is authentic, the cross-border resource transfer auditor may further transfer the cross-border resource from the cross-border resource transfer receiver to the cross-border resource transfer receiver.

Continuing the example above, when it is determined that the trusted voucher corresponding to the study-leaving remittance information for the study-leaving user to perform the study-leaving remittance to the study-leaving institution is trusted, the payment server transfers the study-leaving remittance amount related to the study-leaving remittance information to the study-leaving institution.

For ease of overall understanding, please refer to fig. 2, fig. 2 is a schematic diagram of a cross-border reservation remittance process according to an embodiment of the present disclosure.

As shown in fig. 2, the cross-border reservation remittance management system includes a blockchain constructed based on a number of node devices; the system comprises a payment treasure client side (held by a user side), a school service side (including a server or a server cluster of a school side) corresponding to the payment treasure service side and the school side can be connected to a blockchain network as a member of a blockchain, the payment treasure service side and the school side service side can perform chain interaction based on an intelligent contract which is deployed in the blockchain and used for cross-border reservation remittance management, and a reservation user can be connected to the payment treasure service side through the payment treasure client side to perform cross-border reservation remittance.

As shown in fig. 2, the school side server executes step S202 to submit the reservation payment certification information to the blockchain, and after receiving the reservation payment certification information, the blockchain executes step S204 based on the intelligent contract to generate a trusted certificate corresponding to the reservation payment certification information, and stores the reservation payment certification information and the trusted certificate in an account storage space of a contract account of the intelligent contract; further, the school side server executes step S206 to query the block chain for the trusted certificate, and accordingly, the block chain executes step S208 to return the trusted certificate to the school side server.

As shown in fig. 2, further, the school side server performs step S210 to provide the creditable user with the trusted voucher, the creditable user passes through the payment bank client after obtaining the trusted voucher, performs step S212 to submit remittance information and the trusted voucher to the payment bank server, accordingly, the payment bank server establishes a transaction for verifying the trusted voucher based on the obtained remittance information and the trusted voucher, performs step S214, submits the transaction to a block chain, and performs step S216 to verify the trusted voucher based on the intelligent contract.

As shown in fig. 2, further, the blockchain executes step S218 to return a verification result to the paymate server based on the intelligent contract. And after the verification result is that the transfer is passed, the payer server executes step S220 to initiate the transfer for the leaving school, and after the authenticity verification of the transfer for the leaving school based on the credible certificate is passed, transfers the money transfer amount transferred by the leaving school user into the account of the school student.

As can be seen from the above embodiments, the trans-border resource transfer initiator, the trans-border resource transfer receiver, and the trans-border resource transfer auditor are accessed to the block chain, and an intelligent contract deployed by the trans-border resource transfer auditor based on the block chain generates a trusted certificate for proving trans-border resource transfer information for the trans-border resource transfer receiver, so that in the process of performing resource transfer by the trans-border resource transfer initiator to the trans-border resource transfer receiver, the trans-border resource transfer initiator performs authenticity verification by the trans-border resource transfer auditor based on the trusted certificate provided by the trans-border resource transfer receiver. On one hand, manual participation in authenticity verification is avoided, and authenticity verification efficiency of cross-border resource transfer is improved; on the other hand, the authenticity and the credibility of cross-border resource transfer are ensured.
