the bank transaction platform 200 is configured to, when receiving each product uploaded by the product issuing end 100, obtain product information of each product, and send the product information of each product to the alliance chain framework 400; when a product purchasing instruction sent by a purchaser is received, adding a product corresponding to the product purchasing instruction to a product list of the purchaser, wherein the product list is used for recording various products purchased by the purchaser corresponding to the product purchasing instruction;
the monitoring platform 300 is configured to monitor a product list of the purchaser in real time, generate operation information corresponding to each product when the purchaser performs a business operation on each product in the product list, and upload the operation information to the alliance chain framework 400, where the operation information includes a random number of the purchaser performing the business operation on the product corresponding to the operation information and product information of the product corresponding to the operation information;
the alliance chain framework 400 is configured to, when receiving the information of each product sent by the bank transaction platform 200, sort the information of each product according to a receiving order; carrying out validity check on each piece of product information, and generating a alliance chain block corresponding to each piece of product information when the validity check of each piece of product information is passed; when the operation information of each product sent by the monitoring platform 300 is received, performing validity check on each operation information, and when the operation information passes the validity check of each operation information, setting each operation information as the transaction data of the product corresponding to the operation information, and generating a alliance chain block corresponding to each transaction data; generating actual second transaction information of each product based on each transaction data of each product in the time period, and sending the second transaction information of each product to the bank reconciliation platform 500;
the bank reconciliation platform 500 is configured to receive first transaction information corresponding to each product sent by the product sending end 100 and second transaction information corresponding to each product sent by the alliance chain framework 400; checking the first transaction information and the second transaction information of each product; if the first transaction information and the second transaction information of any product are matched, marking that the product transaction is normal; and if the first transaction information and the second transaction information of any product are not matched, marking the product transaction abnormity and feeding back the abnormity information.
In the intelligent transaction system provided by the embodiment of the invention, the product issuing end 100 generates a corresponding product after receiving the product data uploaded by the user, wherein the product can be a financial product, a fund product or a bond and the like; the product is uploaded to the banking transaction platform 200. The bank transaction platform 200 acquires product information of each product when receiving each product uploaded by the product issuing end 100, wherein the product information includes a product number, a customer number, a serial number, a date, and the like. The serial number of the product is counted by adding 1 to the cancellation number of times of release, which represents that the client tries to release the product for the second time, for example, if the product is released for the first time, the serial number of the product is 0; the product issuing end can put the product off shelf at any time, and when the product issuing end issues the product again, the serial number of the product is the serial number issued last time plus 1. The banking transaction platform 200 issues product information of each product to the alliance chain framework 400, and the purchaser can inquire the product information of each product through the alliance chain framework 400. When the purchaser needs to purchase any product, the purchasing operation is performed only on the banking transaction platform 200. When the purchaser purchases a product issued by the product issuing terminal 100, the banking transaction platform adds the product to the product list of the purchaser. The monitoring platform 300 monitors the list of products of the purchaser in real time to determine whether the purchaser performs a business operation on any of the products in the list. When a certain product is clicked by a purchaser, operation information corresponding to the product is generated and uploaded to the alliance chain framework 400. The alliance chain framework 400 is actually an alliance block chain, and after receiving information of each product sent by the bank transaction platform 200 and information of each operation sent by the monitoring platform 300, the alliance chain framework sorts the received information according to a receiving sequence and performs validity check. And when the product information passes the validity check, generating a alliance chain block corresponding to each product information and each operation information according to the sequencing order. When receiving each operation information, the alliance link framework sets each operation information as transaction data of a product corresponding to the operation information, generates second transaction information of the product based on a preset time period and each transaction data of each product, and sends the second transaction information to the bank reconciliation platform 500, wherein the second transaction information is actual transaction information of the product and cannot be tampered. Similarly, the product issuing end 100 will also account for the first transaction information of each product issued by the product issuing end 100 according to the time period, where the first transaction information is transaction data that the product issuing end 100 performs accounting according to data uploaded by the user, and send the first transaction data to the bank reconciliation platform 500 for reconciliation.
The bank reconciliation platform 500 checks the first transaction information and the second transaction information of each product in the reconciliation process of each product, if the two transaction information are consistent, the user representing the product issuing end does not tamper the transaction information of the product, and marks that the product transaction is normal; otherwise, the transaction information of the product can be tampered, the transaction exception of the product is marked, and the exception information is fed back. And the bank core system checks the reason of the abnormity again according to the abnormal information and checks the abnormity again with the product issuing end.
The system provided by the embodiment of the invention can provide the alliance chain framework for storing the transaction information, and verify whether the product issuing end falsifies the transaction information of the product or not by taking the transaction information in the alliance chain framework as standard information so as to ensure the authenticity of product transaction and operation.

It can be understood that when the push module 201 receives a product, the product is pushed, and meanwhile, product information of the product is sent to the alliance chain framework 400 for storage, so that a purchaser can view each product on a banking transaction platform. When a purchaser checks a certain product, the purchaser can select to check product information of the product, and the query module 202 connects the alliance chain frame to obtain product information of a product corresponding to the product query information according to the product query information sent by the purchaser. When the purchase selects to purchase the product, the product is added to the purchaser's product list.
Optionally, the banking platform 200 may further include a transaction module for maintaining information of all buyers at the banking platform 200.
It should be noted that, since all products issued by the product issuer can be put on and taken off the shelf many times, and the serial number of each product put on the shelf is different from that of the previous one, when the purchaser inquires the product information of a certain product, the product information of the product which is put on the shelf most recently is acquired.
Specifically, when a buyer needs to purchase any product, a purchase agreement between a product distributor and the buyer needs to be constructed, that is, an intelligent contract between the product distributor and the buyer is established, and a benefit between the product distributor and the buyer is maintained through the contract, which specifically includes:
when the purchaser sends a product purchase instruction, sending the product purchase instruction to the product issuing end via the query module 202; when receiving an intelligent contract corresponding to the product purchasing instruction sent by the product issuing end, forwarding the intelligent contract to the purchaser via the pushing module 201; and when the buyer performs a confirmation operation on the intelligent contract, changing the product state of the product corresponding to the product purchase instruction, and adding the product corresponding to the product purchase instruction into the product list of the buyer.
In the intelligent transaction system provided by the embodiment of the present invention, when a purchaser sends a product purchase instruction corresponding to an arbitrary product, an inquiry module sends a product issuing end 100 to which the product purchase instruction is sent, after the product issuing end receives the product purchase instruction, an intelligent contract of the product corresponding to the product purchase instruction is generated and sent to a banking transaction platform 200, a push module 201 in the banking transaction platform 200 pushes the intelligent contract to the purchaser, and after the purchaser receives the intelligent contract and performs a confirmation operation, the inquiry module 202 changes a product state of the product into a sold state and adds the product to a product list of the purchaser.
By applying the system provided by the embodiment of the invention, the transaction of each product is realized through the pushing module and the query module of the bank transaction platform.
Referring to fig. 2, in the intelligent transaction system provided in the embodiment of the present invention, the monitoring platform 300 includes:
a monitoring module 301 and a data generating module 302;
the monitoring module 301 is configured to monitor each product in the product list of the buyer in real time, and determine whether the buyer performs a business operation on any product;
the data generating module 302 is configured to monitor, at the monitoring module 301, that a buyer performs a business operation on any product, determine that a product corresponding to the business operation is a target product, and generate a random number of the target product; acquiring a product serial number corresponding to the target product contained in the product information of the target product; based on the random number and the product serial number, operation information corresponding to the target product is generated, and each operation information is uploaded to the alliance chain framework 400.
In the intelligent transaction system provided by the embodiment of the present invention, in order to ensure the authenticity of the operation performed by the purchaser on the product and prevent the transaction information of each product from being tampered by the user, the monitoring module 301 of the monitoring platform 300 monitors each product in the product list of the purchaser to determine whether a certain product is subjected to a business operation, where the business operation is actually a click operation performed by the purchaser on the product. When a purchaser performs a business operation on a certain product, the data generation module 302 determines the product as a target product, generates a random number corresponding to the target product, associates the random number with the product requirement, generates operation information corresponding to the target product, and sends the operation information to the alliance chain framework 400.
Further, in the process of generating the random number, in order to prevent the random from being tampered, before the data generation module 302 uploads the operation information to the federation chain framework 400, the hash signature is performed on the random number, and the specific process includes:
when the data generation module 302 generates the random number of the target product, a preset monotonically increasing function is embedded in the random number, a hash value corresponding to the random number is calculated, and the hash value is sent to the alliance chain framework 400, so that the alliance chain framework verifies the random number based on the hash value.
