Example two
Referring to fig. 2, fig. 2 is a flowchart of a real-time update method for a blockchain-based fund transaction according to an embodiment of the invention. The blockchain-based fund transaction real-time updating method as shown in fig. 2 may include the following steps:
201. after the processing node processes the allocated sub-transaction, the processing node obtains a sub-processing result corresponding to the processing node, and broadcasts the sub-processing result corresponding to the processing node in the block chain.
In the embodiment of the present invention, the sub-processing result corresponding to the processing node is used to indicate whether the processing node is successful in processing the sub-transaction, where the processing node is any one of the participant nodes of the fund transaction in the blockchain, the fund transaction includes a plurality of sub-transactions, and the sub-transaction of the processing node is any one of the plurality of sub-transactions.
It is appreciated that blockchains are a novel mode of application for computer technology such as distributed data storage, point-to-point transmission, consensus mechanisms, encryption algorithms, and the like.
It is understood that the fund transaction is a circulation transfer activity performed by taking the fund as a buying and selling object and self-bearing the risk and income, and can be classified into an open fund and a closed fund according to whether the fund unit can be added or redeemed, and can be classified into a stock fund, a bond fund, a money market fund, a futures fund, and the like according to the investment object.
In the embodiment of the present invention, the above-mentioned transaction may be an open transaction and a closed transaction, or may be a stock transaction, a bond transaction, a money market transaction, a futures transaction, etc., which is not limited in the embodiment of the present invention.
In the embodiment of the invention, the participants of the fund transaction at least comprise a fund sales participant (such as sales network, individual users and third party sales), a payment participant, a fund management participant (such as a hosting bank) and a share registration participant (an open fund registration transit system, namely a TA system), and correspondingly, the nodes of the blockchain at least comprise a sales participant node, a payment participant node, a fund management participant node and a share registration participant node.
In the embodiment of the invention, the processing node is any party node of the fund transaction in the blockchain, so that the sub-processing results corresponding to the party nodes of the fund transaction are broadcast in the blockchain, each node in the blockchain can acquire the processing result of a certain party to a certain transaction in real time, and further can follow up the processing progress of the transaction.
As an alternative embodiment, step 201 may include:
after the processing node processes the allocated sub-transaction, the processing node performs a summary operation on sub-transaction data related in the process of processing the sub-transaction to obtain encrypted sub-transaction data, obtains a sub-processing result corresponding to the processing node, and broadcasts the sub-processing result corresponding to the processing node in a blockchain, wherein the sub-processing result corresponding to the processing node comprises the encrypted sub-transaction data.
Therefore, in implementing the embodiment, the sub-processing result corresponding to the processing node includes encrypted sub-transaction data, so that the node with decryption authority (having a key) can obtain the sub-transaction data related in the process of processing the sub-transaction by the processing node, and meanwhile, the confidentiality of the data can be ensured.
202. And the verification node verifies the validity of the sub-processing results corresponding to the processing nodes to obtain verification results, wherein the verification node is any party node except the processing nodes in the block chain.
In the embodiment of the present invention, the sub-processing result corresponding to the processing node may be a string of characters (e.g., yes or no), and the verification node verifies the validity of the sub-processing result corresponding to the processing node, that is, verifies whether the string of characters representing the sub-processing result corresponding to the processing node meets the requirement, for example, if the string of characters is scrambled, the string of characters does not meet the requirement, that is, the sub-processing result corresponding to the processing node is illegal.
203. When the verification result indicates that the sub-processing result corresponding to the processing node is legal, the verification node stores the sub-processing result corresponding to the processing node to a public account book in the blockchain.
In the embodiment of the invention, each participant of the fund transaction can inquire the data stored in the public account book.
204. The query node performs transaction query through the public account book to obtain a query result.
In the embodiment of the invention, the query node is any one of the participant nodes in the blockchain, the query result comprises a sub-processing result corresponding to any one of the participant nodes of the fund transaction or a transaction state of the fund transaction, the transaction state is obtained by an intelligent contract in the blockchain according to the sub-processing result of all the participant nodes of the fund transaction, wherein when all the participant nodes of the fund transaction process the respective sub-transactions successfully, the transaction state is a transaction success state, and when any one of the participant nodes of the fund transaction fails to process the sub-transactions, the transaction state is a transaction failure state.
It will be appreciated that a smart contract is a computer protocol that is intended to propagate, verify, or execute contracts in an informative manner. Smart contracts allow trusted transactions to be made without third parties, which transactions are traceable and irreversible.
In the embodiment of the invention, through the intelligent contract in the blockchain, when the fund transaction meets the condition of successful transaction or the condition of failed transaction, the marking work of the transaction state can be automatically executed, so that the state of one transaction can be updated in real time; in addition, the transaction status is saved in real-time in the public ledger of the blockchain, so that each participant of the fund transaction can query the transaction status of the fund transaction in real-time.
Therefore, after the corresponding sub-transaction is processed by any processing node, the sub-processing result of the sub-transaction is broadcasted in the blockchain, so that the verification node can verify the validity of the sub-processing result, and after the verification is successful, the sub-processing result is stored in the public account book, the transaction state of the fund transaction is updated in real time by the intelligent contract, so that all the participant nodes can query the sub-processing result of any one participant node of the fund transaction and the transaction state of the fund transaction in the public account book in the blockchain in real time, the current state of the fund transaction can be timely obtained by a user, the instantaneity is high, and the user experience is facilitated.
Example III
Referring to fig. 3, fig. 3 is a flowchart illustrating another real-time update method for a blockchain-based fund transaction according to an embodiment of the invention. As shown in fig. 3, the blockchain-based fund transaction real-time updating method may include the following steps:
301. after the processing node finishes processing the distributed sub-transactions, obtaining a sub-processing result corresponding to the processing node;
302. the processing node transmits the sub-processing results corresponding to the processing node to a verification node, wherein the verification node is any party node with verification authority in the block chain fund transaction.
In the embodiment of the invention, any one of the above-mentioned participant nodes with verification authority is a participant node with a computing resource in a blockchain greater than a preset computing resource threshold; or any party node with verification authority stores all transaction data of the fund transaction for the account book maintained in the blockchain.
As an alternative embodiment, the participant node with the computing resource greater than the preset computing resource threshold in the blockchain is an authorized node, and the type of the authorized node may at least include: sales party authorization node, payment party authorization node, funds management party authorization node, and share registration party authorization node; the verification node may be an authorized node of a specific type, and therefore, before the processing node transmits the sub-processing result corresponding to the processing node to the verification node, the method may further include the following steps:
The selection node selects an authorized node of a preset type as a verification node, and the selection node is any party node of the fund transaction in the blockchain.
Therefore, by implementing the embodiment, the lightweight node (such as the client node corresponding to the purchase of the personal fund) can not participate in the verification of the processing result, so that the calculation pressure of the lightweight node can be reduced, and the verification efficiency can be improved.
As another alternative implementation manner, considering that the authorized node has more computing resources, it may be limited that only the ledger maintained by the authorized node in the blockchain may store all transaction data of the fund transaction, and the other ledgers maintained by nodes other than the authorized node only store transaction data related to the participant corresponding to the node.
Therefore, by implementing the embodiment, the data privacy can be improved, and the calculation pressure of the lightweight node can be reduced.
303. The processing node broadcasts notification information within the blockchain.
In the embodiment of the present invention, the notification information is used to indicate that the processing node has completed sending the sub-processing result corresponding to the processing node to the verification node.
304. The verification node verifies the validity of the sub-processing results corresponding to the processing node, obtains the verification results, and broadcasts the verification results in the block chain.
305. When the verification result indicates that the sub-processing result corresponding to the processing node is legal, the verification node stores the sub-processing result corresponding to the processing node to a public account book in the blockchain.
As an optional implementation manner, when the verification result indicates that the sub-processing result corresponding to the processing node is illegal, the processing node sends the sub-processing result corresponding to the processing node to another party node with verification authority.
It can be understood that the reasons for the illegal sub-processing results corresponding to the processing nodes indicated by the verification results are various, and may be due to abnormal operation of the verification nodes in addition to the abnormality of the sub-processing results corresponding to the processing nodes, so that by implementing the embodiment, the influence of abnormal operation of the verification nodes can be eliminated by sending the sub-processing results corresponding to the processing nodes to another party node with verification authority by the processing nodes, and further, the influence of downtime of a certain verification node on the whole transaction process is reduced.
As an alternative embodiment, the verifying result includes a node identifier of the verifying node, and when the verifying result indicates that the sub-processing result corresponding to the processing node is illegal, the sending, by the processing node, the sub-processing result corresponding to the processing node to another party node with the verifying authority may include:
And when the verification result indicates that the sub-processing result corresponding to the processing node is illegal, the processing node sends the sub-processing result corresponding to the processing node to another party node with verification authority according to the node identification of the verification node. It can be seen that, by implementing the embodiment, the verification node can be identified by the node identifier, and the sub-processing result corresponding to the processing node is sent to the participant node with verification authority, where the node identifier is not the node identifier carried by the verification result.
306. The query node performs transaction query through the public account book to obtain a query result.
Therefore, by implementing the method described in fig. 3, all the participant nodes of the fund transaction can query the sub-processing result of any one participant node of the fund transaction and the transaction state of the fund transaction in the public account book in the blockchain in real time, so that the user can know the current state of the fund transaction in time, the instantaneity is high, and the user experience is facilitated to be improved; in addition, the verification node is limited to be a participant node with verification authority in the block chain fund transaction, so that not only can the data privacy be improved, but also the lightweight node (such as a client node corresponding to the purchase of the personal fund) can not participate in the verification of the processing result, thereby reducing the calculation pressure of the lightweight node and improving the verification efficiency; in addition, when the verification result indicates that the sub-processing result corresponding to the processing node is illegal, the processing node sends the sub-processing result corresponding to the processing node to another party node with verification authority, so that whether the sub-processing result corresponding to the processing node is illegal or not caused by abnormal operation of the verification node can be judged, and the accuracy of the verification result can be improved.
Example IV
Referring to fig. 4, fig. 4 is a flowchart illustrating a method for updating a blockchain-based fund transaction in real time according to an embodiment of the invention. The blockchain-based fund transaction real-time updating method as shown in fig. 4 may include the following steps:
401. after the processing node processes the allocated sub-transaction, the processing node obtains a sub-processing result corresponding to the processing node, and broadcasts the sub-processing result corresponding to the processing node in the block chain.
In the embodiment of the invention, the processing node is a sales participant node of a fund transaction.
As an optional implementation manner, after the processing node processes the allocated sub-transaction, the processing node obtains a sub-processing result corresponding to the processing node, and broadcasts the sub-processing result corresponding to the processing node in the blockchain, and then the processing node may further include the following steps:
the monitoring node identifies whether the fund transaction is in a subscription stage or not through the intelligent contract; if the fund transaction is in the subscription stage, the monitoring node judges whether the time difference between the current time and the subscription ending time is smaller than the preset duration through the intelligent contract; if the time difference between the current time and the subscription ending time is smaller than the preset duration, the monitoring node pushes the fund transaction to the next participant node of the sales participant node through the intelligent contract.
In the embodiment of the invention, the monitoring node is any party node of the fund transaction in the blockchain.
It will be appreciated that the fund transaction may be in an underwriting stage, i.e., the fund is in a recruitment period, with open investors buying the fund for a period of time, and with actual capital operations performed after the underwriting stage has ended.
It can be seen that, by implementing the embodiment, the fund transaction can be pushed to the next participant node of the participant nodes when approaching the subscription ending time, so that the blockchain can preferentially process the fund transaction needing to be processed immediately.
As an alternative embodiment, if the time difference between the current time and the subscription ending time is not less than the preset duration, the method may further include the following steps:
