Description
Technical Field
The present invention relates to the field of blockchain technologies, and in particular, to a method and an apparatus for confirming a fund transaction based on a blockchain, an electronic device, and a computer-readable storage medium.
Background
The parties typically involved in the fund-seller transaction include: sales channel parties, transaction processing systems, bank paying parties, ta (transfer agent) share registrars.
The current fund sale transaction flow generally means that after a fund investor initiates a transaction (purchase, redemption and the like) on a sale channel side, the sale channel side sends the transaction to a transaction processing system, the transaction processing system processes the transaction, checks and verifies the validity of the transaction, and then sends the transaction to a bank payer to perform corresponding payment processing (deduction during purchase and payment during redemption); and when the day is over, the selling channel party sends the transaction data to the transaction processing system through a file, the bank paying party sends the paid transaction data to the transaction processing system through a file, the transaction processing system checks the daily and over transaction data according to the result of the selling channel party and the result of bank payment, then sends the transaction to the TA share registration party for share registration, and sends the confirmed share to the fund selling end the next day after the share registration.
The current fund sale transaction flow has the following two defects: (1) for investors, when partial system states in a multi-party system do not inform other participant systems in time, the front end of the investor cannot see the final state of the transaction in time, and the final state of the transaction can be updated only after the system of the transaction participant is checked at the end of the day. (2) For system clearing personnel, if more transactions needing intervention processing occur when account checking is finished at the end of the day, the clearing personnel need to coordinate corresponding personnel for processing, more time is spent for processing, clearing time delay is caused, and the timeliness of clearing of a downstream system is influenced by the delay of the clearing time.
In summary, the timeliness of the current fund sales transaction process needs to be improved.

The block chain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like. A block chain (Blockchain), which is essentially a decentralized database, is a series of data blocks associated by using a cryptographic method, and each data block contains information of a batch of network transactions, so as to verify the validity (anti-counterfeiting) of the information and generate a next block. The blockchain may include a blockchain underlying platform, a platform product service layer, an application service layer, and the like.
The embodiment of the application can acquire and process related data based on an artificial intelligence technology. Among them, Artificial Intelligence (AI) is a theory, method, technique and application system that simulates, extends and expands human Intelligence using a digital computer or a machine controlled by a digital computer, senses the environment, acquires knowledge and uses the knowledge to obtain the best result.
Furthermore, it is obvious that the word "comprising" does not exclude other elements or steps, and the singular does not exclude the plural. A plurality of units or means recited in the system claims may also be implemented by one unit or means in software or hardware. The terms first, second, etc. are used to denote names, but not any particular order.
Finally, it should be noted that the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
