Problems solved by technology

[0004] In existing data synchronization technologies, such as Ethereum, Enterprise Operating System (EOS), etc., light nodes cannot self-verify the acquired data. If there are malicious behaviors in the blockchain network, then light nodes It is impossible to determine the accuracy of the obtained data, and thus cannot guarantee the legality of the synchronized data

Abstract

The invention discloses a data synchronization method, a device and a computer readable storage medium. The method comprises the steps that: a data synchronization request transmitted by a light nodeis obtained, wherein the request comprises a block identifier; synchronous transaction data in a synchronous block is acquired according to the block identifier, wherein the synchronous transaction data comprises transaction detail data and contract information; a target data set corresponding to the synchronous transaction data is obtained from a full-volume database, wherein the target data setcomprises read data or result data obtained when the transaction detail data is executed based on the contract information; and verification data of the synchronous transaction data is obtained, and the synchronous transaction data, the verification data and the target data set arereturned to the light node, so that the light node verifies the legality of to-be-verified result data corresponding to the synchronous transaction data and the transaction detail data according to the verification data and the target data set. By the adoption of the data synchronization method, the device and computer readable storage medium, legality verification can be conducted on the synchronized data, and then legality of the synchronized data can be guaranteed.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular to a data synchronization method, device and computer-readable storage medium. Background technique [0002] With the rapid development of network technology and the emphasis on data security by the government and enterprises, the blockchain has received great attention and application. [0003] The blockchain includes full nodes and light nodes. Full nodes have full data and participate in bookkeeping consensus. Light nodes mainly perform business execution and do not participate in bookkeeping consensus. Instead, they obtain block headers from the consensus network through identity authentication. data and block data that is partially authorized to be visible. Therefore, the full number of nodes need to broadcast the block header of the new block after consensus through the peer-to-peer (Peer-to-Peer, P2P) network layer, so that the light nodes can synchronize ...
