Abstract

The invention discloses an implementation method and system of a blockchain distribution network, and the method comprises the steps: enabling each node to measure the connection quality between the node and other peer nodes, and enabling the obtained link state information to be shared with the peer nodes; calculating network topology information according to the link state information, and calculating an adjacent bandwidth resource index of each node; segmenting the network topological graph into k parts, and selecting a node with the highest adjacent bandwidth resource index in each part; taking the nodes as root nodes, and generating a transmission scheduling scheme of the broadcast tree and the non-leaf nodes; issuing a corresponding routing and transmission scheduling method to eachnode, and when broadcasting needs to be carried out in a block chain network, enabling the node to delegate a message to a root node and then carry out broadcasting according to a broadcasting tree. Meanwhile, a corresponding terminal and a medium are provided. According to the invention, through the design and sending planning of the blockchain distribution network, the broadcast delay and message complexity overhead in the blockchain network are reduced, and an efficient, reliable and universal broadcast protocol is provided for a 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 ...
