Problems solved by technology

[0005] When the local node is configured as a non-full record node, it needs to obtain the required data from other nodes in the blockchain network when performing data synchronization. The current existing data synchronization methods are difficult to achieve safe and efficient in the above scenarios. data synchronization

Abstract

The invention provides a data synchronism method and a system. The data synchronism method comprises the steps of: requesting account book data which comprises target data from a destination node, wherein the target data correspond to a data unit which contains a plurality of checking information which connect the each target data to forming the data link by checking data; receiving the account book data being requested and checking; according to the checking information of the data link, the each target datum in the account book datum is orderly connected with each other to form the data link, proceeding the data synchronism one by one according to the each target datum in the data link. In the each account book data stored in a block link by a deal and the target data corresponded to the data unit (such as a data table), some checking information of the data link used for connecting the each target datum to form the data links by checking is deployed by the data synchronism method and the system, which achieves an orderly test for the each acquire target datum and the test for the acquire account book datum, and provides multiple security assurance for the data synchronism.

Description

technical field [0001] This application relates to the technical field of blockchain, and in particular to a data synchronization method and system. Background technique [0002] The blockchain network is a network system based on the distributed principle. Theoretically speaking, the content on each network node is consistent. If you want to obtain the data in the blockchain, you only need to obtain it from any node or a local node. [0003] However, in practical applications, the local node can freely configure the type of the current local node. For example, a local node can be selectively configured as a full-record node (full-node) containing full blockchain data, or a non-full-record node (n-full-node) containing partial blockchain data. [0004] What data is stored locally can be determined by the current local node type and specific configuration, so the blockchain of the local node does not necessarily store all the data of the complete blockchain in the current ne...
