Realization method, system, terminal and medium of blockchain distribution network

Abstract

A method and system for implementing a block chain distribution network, each node measures the connection quality between it and other peer nodes, and shares the obtained link state information with the peer nodes; calculates the network topology according to the link state information information, and calculate the adjacent bandwidth resource index of each node; divide the network topology map into k parts, and select the nodes with the highest adjacent bandwidth resource index in each part; use these nodes as root nodes to generate broadcast trees and non-leaf nodes Transmission scheduling scheme; distribute the corresponding routing and transmission scheduling methods to each node. When it is necessary to broadcast in the blockchain network, the node first entrusts the message to the root node, and then broadcasts according to the broadcast tree. At the same time provide the corresponding terminals and media. The present invention reduces the time delay and message complexity overhead of broadcasting in the blockchain network through the design and transmission planning of the blockchain distribution network, and provides an efficient, reliable and universal broadcast protocol for the blockchain system.

Description

technical field [0001] The present invention relates to the technical field of blockchain network and overlay network, in particular, to a method, system, terminal and medium for realizing a blockchain distribution network. Background technique [0002] Blockchain technology efficiently stores and verifies data through data structures, and uses consensus algorithms to ensure the security, traceability and non-repudiation of data in distributed storage. In recent years, blockchain technology has become a key technology for realizing distributed trust systems, and has received more and more research attention. [0003] A blockchain system needs an underlying network to support its members communicating with each other, exchanging consensus protocol messages and synchronously sharing unconfirmed transaction pools. Therefore, the normal work of the blockchain consensus system depends on the data transmission at the network layer, and the vulnerability of the network layer will ...

AI Technical Summary

Problems solved by technology

However, the message complexity of the system is not considered in this process

When the number of nodes served by the system is large, it will generate higher transmission overhead, which will lead to an increase in the confirmation delay of the consensus protocol

[0005] At present, there is no description or report of the similar technology of the present invention, and no similar data at home and abroad have been collected yet.
