Block chain peer-to-peer network data synchronization method based on height

Abstract

The invention discloses a height-based block chain peer-to-peer network data synchronization method, which comprises the following steps of: calculating an account book data set height which needs to be formally recorded in an account book, wherein an account book recorder broadcasts the account book data set height and an account book data set to an adjacent account book recorder through message broadcasting; the close account book recorder receives the broadcasted message and stores the broadcasted message locally; and each account book recorder sends a node height query request to the surrounding accounting nodes at regular time, compares the height of a request return node with the height of a local node, and starts a difference compensation mechanism to perform data synchronization if the height of the request return node is greater than the height of the local node. According to the invention, on the premise that the block chain network system allows free access of any node, whether the node data is in the latest calculation baseline in the distributed peer-to-peer network system is rapidly and accurately judged; and meanwhile, a synchronization standard and a synchronization range are defined for data replication among different nodes in the peer-to-peer network.

Description

technical field [0001] The invention relates to the technical field of blockchain, in particular to a method for synchronizing data in a blockchain peer-to-peer network based on height, which is suitable for blockchain peer-to-peer network and consensus-consistent blockchain data synchronization. Background technique [0002] The existence of data synchronization is because when the computer stores data, the read and write efficiency of different storage media is quite different, so the cache design is adopted by most computer systems. For a computer with a cache mechanism, when writing data, the system will not immediately write the data to a storage medium with slow read and write speed (such as external memory), but save it in a storage medium with fast read and write speed (such as memory ); when reading data, the system will check whether there is a backup of the data in the storage medium with fast reading and writing speed, and if so, it can directly read the backup. ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a blockchain peer-to-peer network data synchronization method based on height. On the premise that the consensus of the blockchain is consistent, the height can be used to judge whether the unknown data set is consistent, which can effectively Solve the problems of data synchronization and data consistency between blockchain network nodes
