Abstract

The invention provides a blockchain data archiving method and device, and the method is applied to a blockchain node, and comprises the steps: generating an archiving data set based on the block dataof a blockchain system; storing the archived data set in a distributed file storage system; and deleting the archived data set and the block data corresponding to the archived data set. According to the scheme, the block data is packaged and archived to the distributed file storage system, and meanwhile, the locally archived block data is deleted, so that the disk use space of the block chain system can be effectively saved.

Description

technical field [0001] The present application relates to the technical field of blockchain, in particular to a method and device for archiving blockchain data. Background technique [0002] At present, in the actual use of blockchain technology, blockchain nodes generally store data in full. Usually, the bottom layer of the blockchain directly uses a key-value (keyword-value) type database (for example, LevelDB) to store block data and state data. Generally, when using this type of database, it is used directly. Although some key-value databases have a certain compression and archiving function, they only compress storage space to a limited extent. [0003] However, when the blockchain system gradually uses more space in the application, the pressure on the disk will increase. If the blockchain is used to store data unrestrainedly, the storage cost and disk space will become constraints for the blockchain system. the bottleneck. [0004] For the above problems, no effec...
