The Blockchain is a serial transaction record (also called a block) which is connected in series and protects contents by means of cryptography, and is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and the like, and is an essentially decentralised database.
In this embodiment, "decentralization" is a phenomenon or structure that can only occur in systems with numerous users or nodes, each of which can connect to and affect other nodes. Colloquially, it is the center that everyone is, and everyone can connect to and affect other nodes. "decentralization" is one of the typical features of blockchains, which uses distributed storage and computation, the rights and obligations of the entire network node are the same, and the data in the system are essentially maintained together by the entire network node, so that the blockchain no longer depends on the central processing node, and distributed storage, recording and updating of the data are realized. Each blockchain follows a unified rule, the rule is based on a cryptographic algorithm instead of a credit certificate, and the data updating process requires user approval, so that the blockchain is laid down without an intermediary and a trust authority endorsing.
In this embodiment, the target database may be pre-deployed with a smart contract based on a blockchain technology, where the smart contract is implemented by a blockchain technology, and may be a set of digitally defined commitments, including agreements on which contract participants may execute the commitments.

In one embodiment, an intelligent contract can be deployed in advance in the blockchain according to actual needs, and a contract account corresponding to the intelligent contract can be used for recording and maintaining the resource transfer condition of each blockchain account, namely, the resource transfer condition of each blockchain account is recorded and maintained through the intelligent contract deployed in advance based on the blockchain technology. In some embodiments, individual resource transfer cases may also be recorded and maintained in respective blockchain accounts, i.e., individual users' resource transfer cases are recorded and maintained in respective external accounts for individual blockchain users. And in particular, may be determined according to practical situations, which is not limited by the present application.
S203: and sequentially executing a plurality of resource transfer instructions according to a preset sequence according to intelligent contracts deployed in a target database based on a blockchain technology.
In this embodiment, a plurality of resource transfer instructions may be sequentially executed according to the preset sequence according to the intelligent contracts that are pre-deployed in the target database based on the blockchain technology, so that a multi-link automatic resource penetrating transfer process may be completely and safely implemented, and it may be ensured that resources may be safely transferred to the extreme ends of the plurality of resource transfer instructions, and in this process, it may be ensured that information may not be tampered and resources may not be stolen.
In this embodiment, in order to ensure secure resource transfer, the above-mentioned intelligent contract may be configured to enable a next resource transfer instruction of a current resource transfer instruction only if it is determined that the current resource transfer instruction in the resource transfer request is successfully executed, so as to implement sequentially executing a plurality of resource transfer instructions according to the above-mentioned preset order, so as to ensure that resources can be transferred to an end node safely.
From the above description, it can be seen that the following technical effects are achieved in the embodiments of the present application: the resource transfer request can be obtained, wherein the resource transfer request comprises a plurality of resource transfer instructions arranged according to a preset sequence. Further, the resource transfer request may be sent to a target database implemented by using a blockchain technology, and a plurality of resource transfer instructions may be sequentially executed according to a preset sequence according to an intelligent contract deployed in the target database in advance based on the blockchain technology. Therefore, the multi-link resource penetrating transfer flow can be completely and safely realized, the final and safe transfer of the resources to the extreme ends of a plurality of resource transfer instructions can be ensured, and in the process, the information cannot be tampered and the resources cannot be stolen by utilizing the blockchain technology and the intelligent contract.
In one embodiment, according to the intelligent contract deployed in the target database based on the blockchain technology, executing the plurality of resource transfer instructions sequentially according to the preset sequence may include: according to the smart contract, in the case where it is determined that the current resource transfer instruction is the last-stage resource transfer instruction in the preset order, the current resource transfer node of the current resource transfer instruction may be determined according to the current resource transfer instruction. Further, the intelligent contract may forward the current resource transfer instruction to the current resource transfer node, where the current resource transfer node may execute the current resource transfer instruction, and may end a resource transfer flow corresponding to the resource transfer request if it is determined that the current resource transfer node successfully executes the current resource transfer instruction.
In this embodiment, if the current resource transfer instruction is the last-stage resource transfer instruction in the preset order, it is indicated that the resources in the resource transfer request have been transferred to the last link, and after the last-stage resource transfer instruction is completed, all the resource transfer flows requested by the resource transfer request may be ended.
In this embodiment, the current resource transfer node of the current resource transfer instruction may at least include: a resource transfer initiator node and a resource transfer receiver node. Correspondingly, the intelligent contract forwarding the current resource transfer instruction to the current resource transfer node may include forwarding the current resource transfer instruction to a resource transfer initiator node of the current resource transfer instruction, so that the resource transfer initiator node of the current resource transfer instruction may transfer resources to a resource transfer receiver node according to the current resource transfer instruction.
In this embodiment, the resource transfer node may be a node in an intelligent contract, and may be a bank, application software, or the like. When the resource transfer node is a bank, each bank can have an independent intelligent contract node in the process of communicating with the bank, and after the resource transfer is successfully completed, the node of the bank can be actively informed to update the resource transfer state.
In one embodiment, the resource transfer instruction may include: the method comprises the steps of a resource transfer initiator account number, a resource transfer initiator name, a resource transfer node number of the resource transfer initiator, a resource transfer node name of the resource transfer initiator, a resource transfer receiver account number, a resource transfer receiver name, a resource transfer node number of the resource transfer receiver, and a resource transfer node name of the resource transfer receiver. Of course, the information contained in the resource transfer instruction is not limited to the above examples, and other modifications may be made by those skilled in the art in light of the technical spirit of the present application, and it is intended to cover the present application as long as the functions and effects implemented are the same or similar to those of the present application.
In one embodiment, to ensure the reliability of the resource transfer process, before ending the resource transfer flow corresponding to the resource transfer request, the method may further include: and under the condition that the current resource transfer node successfully executes the current resource transfer instruction, the resource transfer state of the current resource transfer node can be updated. Further, the information that the resource transfer state of the current resource transfer node is updated successfully can be sent to the intelligent contract under the condition that the resource transfer state of the current resource transfer node is determined to be updated successfully.
In this embodiment, the current resource transfer node according to the current resource transfer instruction may include at least: the resource transfer initiator node and the resource transfer receiver node can update the resource transfer states of the resource transfer initiator node and the resource transfer receiver node at the same time under the condition that the current resource transfer node successfully executes the current resource transfer instruction, so that the transfer condition of the resource can be effectively recorded in the blockchain, and the safe and complete transfer of the resource can be ensured.
In this embodiment, the information that the resource transfer state of the current resource transfer node is updated successfully may be notified to the intelligent contract when it is determined that the resource transfer state of the current resource transfer node is updated successfully, so that the intelligent contract may trigger execution of a next resource transfer instruction or trigger an operation of ending a resource transfer flow corresponding to the resource transfer request when the information that the resource transfer state of the current resource transfer node is updated successfully is received.
In this embodiment, the information that the resource transfer state update is successful may include: information about the current resource transfer instruction, information that the resource transfer initiator node has initiated the resource transfer, information that the resource transfer receiver node has received the resource transferred by the resource transfer initiator node, and the like. Of course, the above information of successful update of the resource transfer status is not limited to the above examples, and other modifications are possible by those skilled in the art in light of the technical spirit of the present application, but all the functions and effects implemented by the above information are included in the protection scope of the present application as long as they are the same or similar to the present application.
In one embodiment, according to the intelligent contract deployed in the target database based on the blockchain technology, executing the plurality of resource transfer instructions sequentially according to the preset sequence may include: according to the intelligent contract, in the case that the current resource transfer instruction is determined not to be the last-stage resource transfer instruction in the preset sequence, the current resource transfer node of the current resource transfer instruction may be determined according to the current resource transfer instruction, and the intelligent contract may forward the current resource transfer instruction to the current resource transfer node.
Further, the current resource transfer node may execute the current resource transfer instruction, and in the event that it is determined that the current resource transfer node successfully executes the current resource transfer instruction, the intelligent contract may determine a next resource transfer instruction to the current resource transfer instruction. And taking the next resource transfer instruction of the current resource transfer instruction as the current resource transfer instruction, and executing the current resource transfer instruction according to the intelligent contract until the current resource transfer instruction is the last resource transfer instruction in the preset sequence.
In this embodiment, in the case where it is determined that the current resource transfer instruction is not the last resource transfer instruction in the preset order, it is explained that the resource transfer request has not yet been completely executed, and it is necessary to execute the next resource transfer instruction in the preset order in progress. Therefore, under the condition that the current resource transfer node successfully executes the current resource transfer instruction, the next resource transfer instruction of the current resource transfer instruction can be further determined, and the next resource transfer instruction of the current resource transfer instruction is used as the current resource transfer instruction to execute the current resource transfer instruction until the current resource transfer instruction is the last resource transfer instruction in the preset sequence.
In this embodiment, the current resource transfer node of the current resource transfer instruction may at least include: a resource transfer initiator node and a resource transfer receiver node. Correspondingly, the current resource transfer node determined according to the current resource transfer instruction may include: the intelligent contract may forward the current resource transfer instruction to the current resource transfer node, and may include forwarding the current resource transfer instruction to the resource transfer initiator node of the current resource transfer instruction such that the resource transfer initiator node of the current resource transfer instruction may transfer resources to the resource transfer receiver node in accordance with the current resource transfer instruction.
In some embodiments, the smart contract may also forward the current resource transfer instruction to the resource transfer receiver node of the current resource transfer instruction to inform the resource transfer receiver node to record the resource transfer status in time. And in particular, may be determined according to practical situations, which is not limited by the present application.
In one embodiment, to ensure the security of the resource transfer procedure, before the smart contract determines the next resource transfer instruction of the current resource transfer instruction, the method may further include: under the condition that the current resource transfer node successfully executes the current resource transfer instruction, the target resource corresponding to the current resource transfer instruction can be locked, and the resource transfer state of the current resource transfer node can be updated. Therefore, the resources can be effectively prevented from being stolen in the transfer process, and the security of resource transfer can be further enhanced.
In this embodiment, in the case where it is determined that the current resource transfer instruction is not the last-stage resource transfer instruction in the preset order, it is explained that the resource needs to be further transferred, and therefore, before the next resource transfer instruction of the current resource transfer instruction is executed, the target resource corresponding to the current resource transfer instruction may be locked to prevent being stolen.
In this embodiment, the manner of locking the target resource corresponding to the current resource transfer instruction may include: the target resource is marked as reserved resource, so that the target resource cannot be transferred through means such as an internet bank, a counter and the like, and only after the notification of the intelligent contract of the blockchain is received, the target resource can be locked and contacted, and the target resource can be continuously circulated downwards. Of course, the manner of locking the target resource corresponding to the current resource transfer instruction is not limited to the above examples, and other modifications may be made by those skilled in the art in light of the technical spirit of the present application, and all the functions and effects implemented by the present application are included in the protection scope of the present application as long as they are the same or similar to the present application.
In this embodiment, the resource transfer state of the current resource transfer node may be updated under the condition that it is determined that the current resource transfer node successfully executes the current resource transfer instruction, so that the transfer condition of the resource may be effectively recorded in the blockchain, so as to ensure that the resource may be safely and completely transferred. The resource transfer state may be that the target resource has been successfully transferred at the current resource transfer node.
In this embodiment, if an abnormality occurs when the current resource transfer node executes the current resource transfer instruction, or if the execution fails, the execution of the resource transfer may be directly terminated and information about the abnormality of the execution may be fed back to the initiator of the resource transfer request, or the execution of the resource transfer instruction that was executed before the execution may be retried. And in particular, may be determined according to practical situations, which is not limited by the present application.
In this embodiment, the information about the execution abnormality may include: execution progress of resource transfer, abnormality prompt information, cause of occurrence of abnormality, and the like. And in particular, may be determined according to practical situations, which is not limited by the present application. It will be appreciated that in the event of an exception or failure in execution of the current resource transfer instruction by the current resource transfer node, the next resource transfer instruction of the current resource transfer instruction cannot be triggered by the intelligent contract.
In one embodiment, after updating the resource transfer state of the smart contract, it may further include: under the condition that the successful update of the resource transfer state of the current resource transfer node is determined, the information of the successful update of the resource transfer state of the current resource transfer node is sent to the intelligent contract, and the intelligent contract can release the locking of the target resource after receiving the information of the successful update of the resource transfer state of the current resource transfer node. Further, the next resource transfer instruction of the current resource transfer instruction may be continuously executed based on the target resource according to the intelligent contract, thereby determining that the target resource is successfully transferred to the next node.
In one scenario example, as shown in fig. 3, the flow of the resource transfer method may be that the user side may apply for fund transfer according to the actual business flow, and after approval is successful, a set of resource transfer instructions with sequential dependency relationship may be generated, and in particular, the sequence between the plurality of resource transfer instructions may be determined according to the hierarchical relationship of the actual data. Wherein each resource transfer instruction may include payer and payee payment elements associated with the payer and payee for the funds transfer. The payment elements in the resource transfer instructions may include: payer account number, name, bank note number, bank note name and payee account number, name, bank note number, bank note name.
In this scenario example, a set of resource transfer instructions with sequential dependencies in fig. 3 may be sent to the blockchain and retained by a pre-configured intelligent contract in the blockchain, and the adoption of the decentralised intelligent contract may effectively guarantee traceability, non-falsification, and security of the payment order data on the blockchain.
In this scenario example, as shown in FIG. 3, the smart contract may sequentially identify bank features (banks) in the resource transfer instructions from the set of sequentially dependent resource transfer instructions and inform the banks to which the current resource transfer instruction pertains. After receiving the fund payment notice sent by the intelligent contract, the bank can call the transfer account interface to carry out fund payment. If the intelligent contract judges that the payee corresponding to the current resource transfer instruction is not the final node of the through type payment, the funds need to be continuously circulated downwards, the funds need to be locked and marked as reserved amount, so that the funds cannot be transferred through means such as an internet bank or a counter, and the funds can be continuously circulated downwards only under the condition of receiving the intelligent contract notification. If the intelligent contract judges that the collection corresponding to the current resource transfer instruction is the final node of the through payment, each bank involved in the current resource transfer instruction can be directly notified, and after receiving the fund payment notification sent by the intelligent contract, the bank can call a transfer account interface to carry out fund payment without locking the fund. This process loops through until a set of sequential dependent resource transfer instructions of FIG. 3 are executed to the end-most payee.
In this scenario example, as shown in fig. 3, the blockchain has its own independent smart contract node in the process of communicating with banks, and when the fund payment is completed, the smart contract node of the bank can be actively notified to update the state of the fund payment. And under the condition that the state update is successful, sending the information of the successful state update to the intelligent contract to trigger the intelligent contract to further inform the bank node corresponding to the next resource transfer instruction of the current resource transfer instruction to carry out fund payment. In the event that the status update fails, the attempt to update the status may continue until the update is successful.
In this scenario example, the process of the blockchain communicating with the bank may be implemented based on the mutual authentication of the digital certificate in addition to the security mechanism of the blockchain itself, so that the process of transferring the resource is safer and more reliable. The digital certificate based mutual authentication may include: when the bank transmits the state of fund payment to the blockchain, the bank needs to simultaneously transmit information such as SSL (Secure Socket Layer ) protocol version number, encryption algorithm type and the like. After the block link receives SSL information sent by the bank, the public key certificate of the block link end is returned to the bank. The bank uses the information returned by the blockchain to verify legitimacy (whether the public key can unwrap the signature in the certificate, whether the bank side certificate matches the bank side domain name, etc.). The blockchain requires the bank to send its own certificate to the blockchain at the same time; the blockchain verifies the certificate of the blockchain and then obtains the public key of the bank certificate; the bank sends the self-supported symmetrical encryption scheme to the blockchain for the blockchain to select; the block chain encrypts the encryption scheme by using the public key obtained before, and returns the encryption scheme to the bank; after receiving the ciphertext of the encryption mode, the bank decrypts the ciphertext by using the private key of the bank to obtain a specific encryption mode. Then, a random code of the encryption mode is generated and used as a key in the encryption process, and the random code is encrypted by using a public key acquired from the blockchain certificate before and then sent to the blockchain. After receiving the information sent by the bank, the blockchain decrypts the information by using the private key of the blockchain to obtain a symmetric encryption key, and in the subsequent session, the blockchain and the bank can use the key to carry out symmetric encryption to ensure the information security in the communication process.
