Block chain consensus mechanism based on credibility model

Abstract

The invention discloses a block chain consensus mechanism based on a credibility model, and the mechanism comprises the steps: employing a weighted average method to calculate the credibility of nodes, taking the credibility of other nodes voted by a certain node as a weight, calculating the final vote number for each node participating in voting, carrying out the sorting of the final scores of all nodes from high to low, taking the scores in front of preset values as candidates for packaging nodes, after the voting process and the packaging process are successfully finished, rewarding the nodes participating in packaging and successful in packaging and the nodes voting for the nodes, punishing the nodes failed in packaging, the nodes disable in packaging and the nodes voting for the nodes, and combining the rewarding and punishing of the node credibility to update the credibility value. According to the invention, during election, voting is carried out by taking the credibility value as a weight, and the packaging nodes are randomly selected, so that the condition of direct selection is prevented; and a reward and punishment mechanism is introduced, so that the probability of malicious node discovering can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of block chain consensus mechanism, in particular to a block chain consensus mechanism based on reputation model. Background technique [0002] In recent years, service credit has developed rapidly, but there have been some problems in the process of development. The advent of blockchain technology has brought good news to the credit field. Blockchain technology establishes a decentralized consensus mechanism. Through encryption algorithms and consensus mechanisms, participants form A credible environment that checks each other. Blockchain has important application value in solving credit problems. [0003] At present, the consensus mechanisms widely used in the industry are PoW algorithm, PoS algorithm and DPoS algorithm, but all of them have certain shortcomings. The PoW algorithm relies on computing power to compete, which consumes a lot of energy; the PoS algorithm relies on nodes to hold income to fi...

AI Technical Summary

Problems solved by technology

The PoW algorithm relies on computing power to compete, which consumes a lot of energy; the PoS algorithm relies on nodes to hold income to fight for bookkeeping rights, which is easy to cause token hoarding; the DPoS algorithm elects several agents through nodes, and the agents verify and keep accounts. Possibility of malicious nodes and bribery
