Block chain bottom network transaction synchronization optimization method

Abstract

The invention discloses a block chain bottom network transaction synchronization optimization method, which relates to the technical field of block chain bottom P2P network data transmission. A user transmits a transaction to a block chain node 1 in a transaction pool through a client. According to the block chain bottom network transaction synchronization optimization method disclosed in the invention, a transaction which is received but not yet broadcasted can be stored in a transaction buffer pool, transaction information which is already broadcasted and batch hash values can be stored in ahistorical buffer pool, batch transaction hash values which are completed synchronously can be recorded through the received historical transaction hash values, the hash values can be calculated forthe batch transactions through a Merkle tree, only one hash value message is sent when the transaction is subjected to secondary broadcasting, the bandwidth occupancy of the bottom P2P network is greatly reduced, and through building a buffer pool on each node of the block chain and performing hash value calculation on the transaction pool through the Merkle tree, the effect of removing redundanttransaction information is further achieved.

Description

technical field [0001] The invention relates to the technical field of P2P network data transmission at the bottom layer of the block chain, in particular to a method for synchronously optimizing network transactions at the bottom layer of the block chain. Background technique [0002] Blockchain, also known as distributed ledger technology, is an Internet database technology, which is characterized by decentralization, openness and transparency, allowing everyone to participate in database records. P2P is a new network technology that relies on Participants' computing power and bandwidth, instead of relying on a few servers, P2P networks are usually used to connect nodes through AdHoc connections. These types of networks can be used for a variety of purposes, and various file-sharing software are widely used. [0003] In the current blockchain system, as the number of nodes in the entire network increases, the underlying P2P network information of the blockchain will be re...

AI Technical Summary

Problems solved by technology

[0003] In the current blockchain system, as the number of nodes in the entire network increases, the underlying P2P network information of the blockchain will be repeatedly transmitted on the network. These redundant transaction information will occupy a large amount of CPU and bandwidth resources.
