Node synchronization method and apparatus of blockchain

Abstract

The invention provides a node synchronization method and apparatus of a blockchain. The method comprises the following steps: obtaining the information of a plurality of nodes adjacent to a node to besynchronized and the information of a plurality of nodes adjacent to an XOR node of the node to be synchronized, and determining candidate nodes according to the obtained information of the nodes; selecting a first predefined number of nodes from the candidate nodes to serve as newly added nodes; updating a routing table of the node to be synchronized according to the information of the newly added nodes to obtain an updated routing table; and synchronizing the node to be synchronized according to the updated routing table. More node information can be obtained, and the most ideal node can beselected from more nodes to perform synchronization and to update the routing table, so that the synchronization effect is locally optimal. Therefore, it can ensure that the node can obtain the currently confirmed or forked transaction faster and more stably, and the security and reliability of account book recording are ensured. At the same time, the node routing table is also optimized.

Description

technical field [0001] The invention relates to the technical fields of computer applications and block chains, in particular to a block chain node synchronization method and device. Background technique [0002] Currently, the most important blockchain platforms include the Bitcoin platform and the Ethereum platform. Among them, the Ethereum platform expands a generation of encrypted digital currency into a programmable currency, supports third-party developers to develop smart contract applications and issue digital tokens (tokens) in its platform, thus greatly expanding the application scenarios of the blockchain. At present, the Ethereum platform has become the most popular public chain system in the blockchain industry. [0003] An important feature of the blockchain is that each node saves the block information of the entire blockchain. Therefore, it is necessary to update the block data of all nodes on the entire platform synchronously. In the Ethereum platform, a n...

AI Technical Summary

Problems solved by technology

Therefore, when the network status of the adjacent nodes of the current node is not good, such as when the network is often disconnected or the network throughput is limited, node synchronization failures often occur

Once the synchronization fails, the transaction status of the current node will not be the latest status, which will bring great security problems
