Abstract

The invention provides a data synchronization method and device for a business data block chain, and relates to the technical field of block chains, and the method comprises the steps that a block chain node receives a to-be-synchronized block, the to-be-synchronized block comprises a block head and a block body, the block head comprises a tree root of a first state tree, and the block body comprises block data; a third state tree is created according to the block data and the second state tree of the local current block; the root of the third state tree is calculated through a preset rule; and the tree root of the first state tree is compared with the tree root of the third state tree, if the tree roots are the same, the second state tree is updated into the third state tree by the blockchain node, and the to-be-synchronized block is linked behind the local current block. Therefore, based on the generation logic of the state tree, the completeness of the synchronized data, whether thesynchronized data is tampered or not and other conditions can be verified. The data synchronization efficiency is improved, the data tampering cost is increased, and the data security is ensured.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a data synchronization method and device for block chains of business data. Background technique [0002] At present, blockchain technology is a distributed storage ledger that uses technologies such as encryption algorithms and consensus mechanisms. With the application of blockchain technology, more and more Internet data will be stored on the blockchain. [0003] In the existing blockchain, only transaction data can be stored, and the transaction data includes the address of the transfer party, the address of the receiver, and the transfer amount; for various business data (such as: deposit data, traceability data, financial data, travel data, search data, self-media data, research data, advertising data, e-commerce data, community data, knowledge quiz data, knowledge payment data, shared bicycle data, recruitment data, life service data, rental data, voting data, OTO da...
