The customers can be divided into individual users and enterprise users, and initiate transaction requests in various ways such as money transfer, payment and the like.

The transaction system is usually an Enterprise ERP (Enterprise Resource Planning) system or a third party payment system, and provides transaction service for customers by accessing a bank system.

A transaction bank refers to a financial institution that operates monetary credit services in accordance with the establishment of a law, typically a customer's bank of accounts, as a payer of a financial exchange.

The bank system refers to a bank card network transaction transfer clearing platform created by China Union Pay and commercial banks, and all banks realize transaction intercommunication among different banks through the bank cross-bank transaction clearing system.

The adversary bank refers to a financial institution that operates a monetary credit business in which the law is established, as a payee of a fund transaction.

In the embodiment of the invention, the blockchain can be regarded as a fund transaction data sharing database, records fund circulation in a blockchain transaction mode, stores transaction details and can provide account checking service according to the non-tampering characteristic of the blockchain.

For further understanding of the embodiments of the present invention, the following describes an application scenario based on the system architecture shown in fig. 4.

1. Transaction request submission scenario

The client submits a cross-bank transaction request in the transaction system, the transaction system submits an instruction to a transaction bank, the transaction bank calculates the blockchain identifier according to the instruction data, the instruction containing the blockchain identifier is submitted to the Unionpay system after various verifications are carried out, and the Unionpay system submits the instruction containing the blockchain identifier to an opponent bank for settlement. Each system stores the blockchain identification locally for subsequent reconciliation scenario use.

2. Transaction result confirmation scenario

And the Unionpay system returns the transaction information to the transaction bank after settlement. In the settlement process, the fund increase is carried out on the opponent bank, the fund deduction is carried out on the transaction bank, and the two processing results are kept consistent. And the transaction bank uploads the transaction information to the block after receiving the successful command of the Unionpay system, and then writes the block transaction information record into the block chain.

3. Transaction reconciliation scenario

The reconciliation process widely exists between a client and a transaction system, between the transaction system and a transaction bank, between the transaction bank and a unionpay system, and between the unionpay system and an opponent bank. In the embodiment of the invention, each system searches each block in the block chain by using the block chain identifier as the key word, if the record exists, the record is successfully processed, other detailed information can be further selected by self definition, and if the block chain record does not exist, the corresponding accounting processing fails. By the system, account checking logic can be simplified, and state consistency among multiple systems is ensured.

In practice, a plurality of transaction data (or called transaction records) are stored in a block, and the block storing the transaction data may be called a block transaction.

Fig. 5 is a schematic structural diagram of each block transaction, as shown in fig. 5, the block transaction includes: last chunk hash value 501, mercker root 502, timestamp 503, transaction content 504, where:

last chunk hash value 501: calculating the last block (Tx)_pre) As the last transaction ID input, the SHA-256 algorithm based hash value of (a).

Mercker root 502: and performing two-group Hash calculation on all the transaction information to obtain a final Hash value, wherein the Hash value can quickly verify the integrity of the transaction data.

Time stamp 503: the time of production of this block is recorded. Generally, each time a block is generated, a corresponding time stamp is attached to ensure that the blocks on the entire chain are arranged in time sequence.

Transaction content 504: the transaction content is composed of transaction related fields, user transaction Data is recorded in detail, different transaction contents can be generated in a configurable mode according to different transaction service types, and a Data Encryption mode can be set according to customer requirements, and the Data Encryption mode is usually a symmetric Encryption algorithm, such as Data Encryption Standard (DES), Advanced Encryption Standard (AES) and the like.

In one embodiment, when a customer initiates a transaction, the transaction data may include money transfer remittance, surreptitious wages, shopping payments, and the like. Each transaction datum contains payer information, payee information, transaction currency, usage summary, transaction time, etc., which are stored in transaction content 504.

As can be seen from the above description, the operation data processing system based on the block chain according to the embodiment of the present invention can solve the problem of tedious reconciliation between multiple systems, and improve the reconciliation efficiency. Particularly, the design of transaction record and account checking is carried out based on the block chain technology, so that the data safety and convenient and fast traceability of the account checking can be realized, and the accuracy and timeliness of the account checking are ensured to the maximum extent. The method has the following specific advantages:

1. and (3) data security: the safety and the privacy of transaction data are guaranteed by a blockchain technology, the transaction information is stored and encrypted on private information of a blockchain and can be checked only through a secret key, and therefore the safety and the privacy of the transaction data of a client are guaranteed. On the other hand, the non-tamperable nature of the blockchain itself also avoids manual alteration of the transaction information.

2. Transaction traceability: the transaction data is recorded on the block chain, so that the source, the use and the circulation path of the transaction are determined, the transaction record can be ensured to be accurate and traceable, and each transaction data is traceable.

3. Account checking is convenient: by adopting a centralized account checking mode, each system takes the block chain system as a unified account checking reference, the transmission consumption of account checking between every two systems in the conventional account checking can be reduced, the comparison efficiency is improved, and the account checking efficiency can be improved.

Based on similar inventive concepts, the embodiment of the present invention further provides a method for processing job data based on a block chain, and the method is preferably applicable to the above apparatus.
