Abstract

The present application proposes a data backup method, which includes: when a first condition is satisfied, querying and obtaining unused transaction output information from a first block in a first block chain, where the first block includes all All blocks in the first blockchain; generate transaction information according to the unused transaction output information obtained by the query, and the transaction information is used to describe the account address to which the unused transaction output information belongs without changing the transaction operation; record the generated transaction information in the second block and publish the second block, and record the consensus second block on the second blockchain; and The first blockchain is backed up in the storage system connected to itself, and the first blockchain is deleted. The present application also proposes a corresponding data backup device, storage medium and computing device. Adopting the above scheme can save the storage space of the blockchain node.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular, to a data backup method, apparatus, storage medium, and computing device. Background technique [0002] The so-called blockchain technology, referred to as BT (Blockchain Technology), also known as distributed ledger technology, is an Internet database technology, which is characterized by decentralization, openness and transparency, allowing everyone to participate in database records. Blockchain technology is used in various fields such as finance. Since each node device in the blockchain will store all the data on the entire blockchain, it will occupy a lot of storage space and affect the performance of the blockchain system. SUMMARY OF THE INVENTION [0003] The embodiments of the present application propose the following technical solutions to save the storage space of blockchain nodes and improve the performance of the blockchain system. [0004] An exampl...
