Embodiment Construction

[0069] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0070] figure 1 It is a schematic diagram of the network communication mode of the blockchain system. Each node 200 is connected through the Internet. Generally speaking, the blockchain system uses P2P network technology to connect peer nodes for networking, thus forming a decentralized network structure. For example, the blockchain system of Ethereum adopts the Kademelia P2P communication protocol based on DHT (Distributed Hash Table, Distributed Hash Table) at the network layer to realize communication between nodes.

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...
