Full association voting method based on block chain equity authorization certification consensus mechanism

Abstract

The invention relates to a full-association voting method based on a block chain equity authorization certification consensus mechanism. The method comprises the following steps: firstly, selecting preference information of each node for a certain node from a symmetric language term set to vote; voting information of all block chain nodes is collected, probability distribution information of language terms is calculated, and a proportional hesitant fuzzy language term set is used for modeling group voting information of each block chain node; group voting information of n block chain nodes in the block chain network can be expressed as n proportional hesitant fuzzy language term sets; performing pairwise comparison on all block chain nodes to obtain a second-level possibility degree matrix; calculating the cumulative possibility degree of each block chain node i; sorting the accumulated possibility degrees of the n block chain nodes in a descending order; and finally, according to the preset number m of agent nodes, selecting the block chain nodes with the accumulated possibility ranked in the first m as representatives, and by adopting the technical scheme, the fairness of an equity authorization certification consensus mechanism is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of block chain consensus, in particular to a fully associated voting method based on block chain equity authorization certificate consensus mechanism. Background technique [0002] Blockchain can provide a trusted, secure and efficient environment for different application scenarios. It has been successfully applied in transportation systems, industrial Internet of Things systems, medical information sharing platforms, and smart cities. [0003] Blockchain consists of four core technologies: distributed ledger, asymmetric encryption, smart contract and consensus mechanism. The distributed ledger adopts a decentralized design concept and builds a blockchain platform as a distributed network. Users are free to join the distributed blockchain network and participate in transaction recording activities. At the same time, when the number of people involved is constantly increasing, there is often no co...

Problems solved by technology

[0005] So far, only the research of Xu Guangxia's team at Chongqing University of Posts and Telecommunications has focused on how to represent the group voting information of the voted blockchain nodes, but it still faces a major challenge, that is, it does not take into account the strength of "support" and "opposition". In this case, it may lead to the problem of information loss, thereby reducing the accuracy of knowledge representation
