Blockchain representative node selection method and device, computer equipment and storage medium

Abstract

The invention relates to a blockchain representative node selection method and device, computer equipment and a storage medium. The method comprises the following steps: obtaining an opportunity value corresponding to each node in a node set composed of a plurality of nodes participating in the round of election, and determining at least one quasi-representative node from the node set according to the opportunity value corresponding to each node, wherein the opportunity value of the quasi-representative node is greater than a predetermined target value; obtaining a guessing value of each quasi-representative node during random number guessing in the current round of competition, and determining the representative node of the current round of competition from at least one quasi-representative node according to the guessing value. Compared with a conventional method for determining representative nodes through a voting mechanism, the method has the advantages that an excitation mechanism is set for node competitions, the representative nodes of each round of competitions are determined through opportunity values of the nodes and an introduced random number guessing mechanism, and therefore the centrality of the representative nodes is weakened, and the centralization degree of the representative nodes in the blockchain is reduced.

Description

technical field [0001] The present application relates to the technical field of blockchain, in particular to a method, device, computer equipment and storage medium for selecting a representative node of blockchain. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. It is essentially a distributed shared ledger and database. The blockchain has the characteristics of decentralization. However, in the blockchain, there are usually problems with low participation of certain nodes and invalid or malicious blocks. This leads to a high degree of centralization of the blockchain, so it is necessary to reduce the generation of invalid blocks or malicious blocks in the blockchain network. At present, the elimination of malicious blocks or invalid blocks usually adopts a voting mechanism to eliminate inactive nodes. However, this met...

AI Technical Summary

Problems solved by technology

It is essentially a distributed shared ledger and database. The blockchain has the characteristics of decentralization. However, in the blockchain, there are usually problems with low participation of certain nodes and invalid or malicious blocks. This leads to a high degree of centralization of the blockchain, so it is necessary to reduce the generation of invalid blocks or malicious blocks in the blockchain network

At present, the elimination of malicious blocks or invalid blocks usually adopts a voting mechanism to eliminate inactive nodes. However, this method still cannot avoid the problem of low participation of nodes, resulting in a high degree of centralization in the blockchain

[0003] Therefore, the selection of representative nodes in the current blockchain has the defect of a high degree of centralization
