Abstract

The invention relates to a block chain data backup method and device, a storage medium and electronic equipment. The method comprises the following steps: obtaining state information of block chain data of a target node; under the condition that the state information represents that the block chain data of the target node is changed, obtaining change data of the block chain data; adding the change data as to-be-backed-up data into a backup processing sequence; and asynchronously storing the data to be backed up in the backup processing sequence into a backup data space. According to the technical scheme, the effect of backing up the block chain data of the target node can be achieved. Moreover, the backup mode is independent of the block chain data processing logic of the target node, so that the influence of the backup process on the block chain data processing performance of the target node can be reduced.

Description

technical field [0001] The present disclosure relates to the technical field of blockchain, and in particular, to a blockchain data backup method, device, storage medium and electronic equipment. Background technique [0002] Blockchain technology is a technology that can collectively maintain a reliable database through decentralization and trustlessness. Due to the non-tamperable and traceable properties of blockchain ledgers, blockchain technology has broad application scenarios in cross-border payment, credential business and financial fields. [0003] In related scenarios, the blockchain ledger may also be damaged, which will affect the related transaction process. Contents of the invention [0004] The purpose of the present disclosure is to provide a blockchain data backup method, device, storage medium and electronic equipment to solve the above-mentioned related technical problems. [0005] In order to achieve the above purpose, according to the first aspect of ...
