Problems solved by technology

During the block synchronization process, the newly added node needs to verify the digital signature of each transaction in the downloaded block, and the block will be added to the node's own blockchain copy only if the verification is passed In general, the time it takes to verify the digital signatures of all transactions is several times that of downloading blocks, and it is very time-consuming, making the entire block synchronization time very long

Abstract

The invention discloses a block synchronization method and system, wherein the method is applied to a block chain network; furthermore, according to block mark numbers of block chains, snapshot blocksand snapshot intervals formed by separation of the snapshot blocks are pre-defined; a miner node judges whether a current block to be packaged is a snapshot block or not according to the block mark number of the current block to be packaged; if the current block to be packaged is the snapshot block, the snapshot block, the block head of which includes snapshot field information, is generated; a conventional node verifies the snapshot block and the snapshot field information; the snapshot block passing verification is added into a block chain copy of the node itself; a newly increased node downloads a pre-set number of blocks from the conventional node, wherein the snapshot block is included in the pre-set number of blocks; the snapshot field information in the block head of the snapshot block is utilized for verifying trade information in the downloaded blocks; therefore, the check time of transaction signature in the existing technical scheme is reduced; and furthermore, the block synchronization speed of the newly increased node is also greatly increased.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a block synchronization method and system. Background technique [0002] Blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is a cryptographically guaranteed non-tamperable and unforgeable distributed ledger. Wherein, each block is also a data block, and each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block. [0003] In the blockchain network, after the miner node produces a new block, it broadcasts the block. After receiving the block, other regular nodes in the network will verify its legitimacy; if it passes the verification, the regular node will add the block to the local blockchain. Each node in the blockchain network stores a blockchain. [0004] For a node newly added...
