Embodiment Construction

[0053] In order to make the object, technical solution and advantages of the present invention clearer, the present invention 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 invention, not to limit the present invention.

[0054] The trusted blockchain network model is constructed as an undirected graph G=(V,E), each vertex describes a node in the network, and each edge connects two nodes within the transmission range of each other, such as figure 1 As shown, in this model, two entities are defined, which are formalized as a set of eigenvectors

[0055] Network Node includes a node attribute vector (Node Attributes) and a node capability vector (Node Capacity); the node attribute vector includes trust evaluation, transaction times, successful transaction times, stable running time, total running time and processing t...

Abstract

The present invention is applicable to the field of block chain technology, and provides a trust degree calculation method based on trust block chain nodes, including the following steps: S1, for nodes in the trust block chain network, based on the transaction trust value C of the node d and behavior trust value F b to calculate the comprehensive trust value of the node; S2, adding a time stamp to the comprehensive trust value of the node to form a comprehensive trust value with a time stamp. The trust value generated by the comprehensive node transaction and the trust value generated by the node behavior are used to calculate the comprehensive trust value of the node, and the trusted node is selected based on the comprehensive trust value to effectively ensure the security of the blockchain network environment, while reducing the average transaction delay and improving Block rate.

Description

technical field [0001] The invention belongs to the technical field of block chains and provides a trust degree calculation method based on trusted block chain nodes. Background technique [0002] The blockchain network is a decentralized P2P network. Each node needs to perform operations with the nodes connected to itself, and there will be trust problems in the process of node interaction. The blockchain is considered to be the value of the Internet, and it exists to solve the trust problem of production relations. The problem is that so-called "trustless" blockchains don't improve people's trusting relationships with them. Although there are many technical advantages about blockchain, distributed ledgers and smart contracts, among which there are characteristics such as non-tamperable, traceable, open, transparent, encryption algorithm and trust relationship, but still need to face the trust of blockchain technology itself Crisis, that is, whether the behavior of blockc...
