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

Abstract

The present application relates to a method, device, computer equipment and storage medium for selecting a blockchain representative node. By obtaining the chance value corresponding to each node in the node set composed of multiple nodes participating in this round of election, and according to the chance value corresponding to each node, at least one quasi-representative node is determined from the node set, wherein the quasi-representative node The chance value is greater than the predetermined target value, and then obtain the guess value of each quasi-representative node when guessing the random number in this round of election, and determine the representative node of this round of election from at least one quasi-representative node according to the guess value. Compared with the traditional method of determining representative nodes through a voting mechanism, this scheme sets an incentive mechanism for node elections, uses the node's chance value and the introduced random number guessing mechanism to determine the representative nodes for each round of elections, thereby weakening the The centralization of representative nodes reduces the centralization of representative nodes in the blockchain.

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...

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
