Embodiment Construction

[0054] Exemplary embodiments of the present invention are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present invention to facilitate understanding, and they should be regarded as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

[0055]The essence of the blockchain is a shared database. The data or information stored in the blockchain has the characteristics of "unforgeable" and "retaining traces throughout the process". Based on this, the blockchain can be integrated into the transfer process of the traditional banking system. For example, in the scenario of cross-border payment, the blockchain ca...

Abstract

The invention discloses a transaction consistency processing method and device based on a block chain, and relates to the technical field of block chains. A specific embodiment of the method comprises the steps of receiving a first transaction request, wherein the first transaction request indicates a transaction amount; sending the first transaction request to a transaction system, so that the transaction system performs transaction according to the transaction amount; in response to transaction abnormity of the transaction system, executing asynchronous processing corresponding to the first transaction request by adopting a first asynchronous processing thread; in response to successful transaction of the transaction system, sending a second transaction request to the block chain according to an execution result of the first transaction request, the second transaction request indicating a transaction amount; and in response to transaction abnormity of the block chain, executing asynchronous processing corresponding to the second transaction request by adopting the first asynchronous processing thread. According to the embodiment, the consistency guarantee of the transaction between the transaction system and the block chain is enhanced, so that generation of wrong accounts in a special abnormal scene is avoided or reduced.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a method and device for processing transaction consistency based on block chains. Background technique [0002] There are two scenarios for integrating the blockchain into the transfer process of traditional banks: 1) first debit the bank account, and then enter the account on the blockchain, which is called deposit; 2) first perform the blockchain The off-chain deduction, and then the bank account entry, is called withdrawal. [0003] In the above transfer process, due to the different bookkeeping parties, one is the banking system and the other is the blockchain, it is impossible to use the traditional bank record method or the traditional third-party organization method for bookkeeping. Therefore, the deduction between the banking system and the blockchain It is difficult to guarantee the transaction consistency with the account. Contents of the invention [0...
