Blockchain-based Consensus Method for Internet of Vehicles Node Consensus

Abstract

The invention relates to a block chain-based vehicle networking node consistency consensus method, which divides the nodes in the network into verification nodes and general nodes, and performs identity verification and identity conversion for the two types of nodes; FMC clustering is used to realize four types of nodes Credit rating division, giving different rights to nodes according to credit rating; determining the verification nodes and number participating in the block consensus according to the scope of the transaction, and establishing a communicable list and a trusted list; the consensus is mainly divided into transaction set consensus and block competition construction Two parts, the consensus of the transaction set is determined by the voting results of the nodes on the trusted list, and the block competition construction is calculated by the nodes with credit rating A on the transaction consensus results, and verified by other nodes that do not participate in the block construction . The method of the invention is suitable for the network environment under large-scale transactions, improves the enthusiasm of nodes to participate in block consensus, improves the consensus throughput of large-scale transactions, and reduces the time for transaction consensus.

Description

Technical field: [0001] The present invention relates to the field of blockchain, in particular to a method for consensus consensus of Internet of Vehicles nodes based on blockchain. Background technique: [0002] With the development of 5G (5th-Generation, 5G) technology with more efficient network speed, low power consumption, low latency and other characteristics, major changes will take place in the Internet of Vehicles (Internet of Vehicles) and other fields, that is, vehicles with Internet of Vehicles 5G technology can be used to realize rapid perception and real-time decision-making on complex road sections with serious roadside facilities defects, irregular deployment, large traffic flow and fast vehicle speed. And thanks to my country's leading advantages in the field of 5G technology and the huge scale of the automobile market, my country's Internet of Vehicles industry has entered the "fast lane". According to data from China Unicom, it is estimated that in 2020,...

Problems solved by technology

[0005] In short, the block consensus speed of the current POS mechanism is relatively slow, and nodes need to waste a lot of computing resources. Based on the POS mechanism and DPOS mechanism, there are problems such as the power of the richest node is relatively large, and it is prone to cumulative attacks or poor node voting enthusiasm.

None of the above existing methods are suitable for network environments with large real-time transaction volume
