Abstract

The invention provides a data backup method and device in a block chain system, the block chain system comprises a first fragment, the first fragment comprises a first fragment node, the first fragment has a corresponding first standby node, and the method is applied to the first fragment node, and the method comprises the following steps: generating state information in a process of executing a first block; and sending the state information to the first standby node. Therefore, the state data generated by the first fragment node can be effectively backed up on the premise of not influencing the performance and throughput of the block chain system.

Description

Technical field [0001] One or more embodiments of the present specification relate to the field of block chains, and more particularly to methods and apparatus for data backups in a block chain system. Background technique [0002] The block chain is a new application model of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technology. From essentially, it is a shared database, stored in it, has difficult to tamper, go to the center Features. Block chain technology has great application potential in financial, public welfare, justice, transactions and other scenes. [0003] Currently, in the block chain system, the data of the block chain is usually backed up by deploying a node with backup functions. The node is involved in consensus and also participates in the implementation of the transaction. After performing any of the blocks, the node can back up the data of the block. Therefore, the performance and throug...
