Block chain data rollback processing method and processing system thereof

Abstract

The invention provides a block chain data rollback processing method and system, and the method comprises the steps: firstly detecting and verifying the newly-added business data of a user, writing the newly-added business data into a preset database, verifying whether the business data is abnormal or not in the writing process, transmitting the business data to a verification node for confirmation, and writing a block confirmed by the verification node into a block chain; if the block chain is abnormal, the consensus node generating and sending a data rollback request to the consensus leader node for verification, and the consensus leader node generating a data rollback structural body, signing the data rollback structural body and sending the signed data rollback structural body to the block chain network; the consensus node receiving and verifying the data rollback structural body, and if the verification is passed, generating a sponsored ticket; and the consensus leader node counting the number of sponsored tickets and judging whether rollback operation can be carried out or not. According to the block chain data rollback processing method and the processing system thereof provided by the invention, the risk of dirty data problem is reduced, the data rollback of the block chain is conveniently realized, and the user loss caused by rollback can be subjected to insurance compensation.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a block chain data rollback processing method and a processing system thereof. Background technique [0002] In traditional databases, administrators have the right to modify the database arbitrarily, which means that the data in the database is abnormal, and the administrator can correct the data by himself. The essence of the blockchain is a chained database, but in the blockchain, there is no such administrator. It can only add and check data, but cannot delete or modify it. To achieve data correction, all users must agree to it. Yes, so once the data is on the chain, it cannot be tampered with. Moreover, when processing new business data, the first is to execute the chain write operation of the blockchain, and then execute the database write operation. When an exception occurs in the database write database, it often needs to cause the rollback operation of the blockcha...

The essence of the blockchain is a chained database, but in the blockchain, there is no such administrator. It can only add and check data, but cannot delete or modify it. To achieve data correction, all users must agree to it. Yes, so once the data is on the chain, it cannot be tampered with

Moreover, when processing new business data, the chain write operation of the blockchain is first performed, and then the database write operation is performed. When an exception occurs in the database write database, it often needs to cause a rollback operation of the blockchain. At this time, due to The blockchain fails to increase transaction processing, and there will be problems with dirty data. When the blockchain is rolled back, the losses caused by users are often not compensated by insurance. Therefore, a new blockchain data rollback processing method is designed. and its processing system is very necessary
