Abstract

The invention discloses a blockchain state data synchronization method based on Rsync, and the method comprises the steps: packaging the state data of all block nodes in a blockchain into an object, storing the object in a message queue, and reading the data of each block node from the message queue one by one; based on the block data of each block node, uniformly dividing the block node into a plurality of sub-data blocks according to the size of the data volume, and numbering the plurality of sub-data blocks; based on an Rsync algorithm, calculating a strong verification value and a weak verification value of each sub-data block; inputting the sub-data blocks and the corresponding strong check values and weak check values to the Rsync client; based on a synchronous source file of the Rsync client, searching for a corresponding weak verification value and a strong verification value, and screening out sub-data blocks lacking the weak verification value and/or the strong verification value; on the basis of the synchronous source file, replacing the sub-data block without the verification value. The problem of unbalanced node load in the blockchain data synchronization process is solved, the data synchronization performance in the block network can be improved, and the required computing resources are less.

Description

Technical field [0001] The present invention relates to the field of block chain data synchronous techniques, and more particularly to a block chain state data synchronization method and system based on RSYNC. Background technique [0002] Data synchronization is a very important process in the block chain, from functionality to transaction synchronization and status synchronization. The existing block chain status data synchronization method is: Backward block nodes need to download blocks from other nodes by request, other nodes respond after receiving the request, that is, send missing data to backward block nodes. . Since there is a plurality of nodes in the block chain, there is a large number of requests-response processes during the existing status data synchronization process, which requires a lot of information in the request - the response process, which means that a large amount of resources need to be consumed. In addition, the process of request-responding is random,...
