Problems solved by technology

At present, the selection of consensus nodes is usually done through DPoS (Delegated Proof of Stake, Proxy Proof of Interest) or PBFT (Practical Byzantine Fault Tolerance, Practical Byzantine Fault Tolerance Algorithm). Cyber ​​attack, destroying the consistency of blockchain nodes
[0004] Therefore, the current blockchain consensus node selection method has the defect of low security

Embodiment Construction

[0068] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0069] The blockchain consensus node selection method provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the server 102 and the server 104 may be nodes set in the same block chain, the server 102 may be a node, and the server 104 may be formed by a server cluster composed of multiple nodes. Server 102 communicates with server 104 over a network. When the server 102 needs to select a node in the block chain, such as when the block chain task starts, it can obtain the verification information corresponding to the ...

Abstract

The invention relates to a block chain consensus node selection method and device, computer equipment and a storage medium. The method comprises the steps of broadcasting verification information of the node to other nodes in the block chain, and when a set number of first verification passing information is received, determining the node as a candidate node; and when the node is a candidate node, broadcasting verification information of the candidate node to a plurality of candidate nodes in the candidate node set, and when a set number of second verification passing information is received, determining that the candidate node is a main node. Compared with a traditional method for selecting nodes through proven of rights and interests or a practical Byzantine fault-tolerant algorithm, according to the scheme, multiple rounds of verification are carried out by utilizing verification information formed based on various node information and a verifiable random function, the randomness of node selection is improved, network attacks carried out through predicted nodes are prevented, and the effect of improving the node security is achieved.

Description

technical field [0001] The present application relates to the technical field of block chains, in particular to a block chain consensus node selection method, device, computer equipment and storage medium. Background technique [0002] Blockchain is a decentralized distributed system. All nodes in the network jointly maintain a public ledger that holds all data in the network. Therefore, the consensus algorithm is the core of blockchain. Its function is to fairly select designated nodes to pack transactions into blocks and add the blocks to the blockchain. Other nodes in the network agree with this operation, so that all nodes in the blockchain network maintain the same consistency. A chain, the consensus algorithm allows the blockchain to run stably without a central authority, so its security directly determines the security of the blockchain system. [0003] With more and more nodes and transaction volume in the blockchain network, the speed of consensus and transaction ...
