In order to improve the effectiveness of safe, high-quality, and efficient communication mechanism ideological political courses in new media perspective, path perspective based on blockchain technology is designed. Mainly through organic combination online communication, offline-online dynamic feedback, offline structure, an information transmission leading feedback formed. this path, network ...

Although the current Domain Name System (DNS) has been able to satisfy use of network services, there are still many challenges in future development Internet. The centralized management traditional domain name systems risks, and cannot defend against Distributed Denial Service (DDoS) attacks single points failure. As a decentralized tool, blockchain provides innovative ideas for improvement sy...

This paper uses blockchain technology to conduct in-depth research and analysis on enterprise cost optimization control. Based the of control status in enterprises, concept target specific ideas are proposed. And study under based genetic algorithm is carried out combination with current three major controls quality, schedule, cost. It provides technical basis for realization profit enterprise....

The extensive application of the Internet Things in industrial field has formed (IIoT). By analyzing and training data from Things, intelligent manufacturing can be realized. Due to privacy concerns, various institutions cannot shared, which forms islands. To address this challenge, we propose a privacy-preserving aggregation federated learning (PPDAFL) scheme for IIoT. In learning, is adopted ...

We present new protocols for Byzantine state machine replication and Byzantine agreement in the synchronous and authenticated setting. The celebrated PBFT state machine replication protocol tolerates f Byzantine faults in an asynchronous setting using 3f +1 replicas, and has since been studied or deployed by numerous works. In this work, we improve the Byzantine fault tolerance threshold to n =...

conclusions the results of this study show that narrative therapy is a suitable approach for solving couples’ conflicts. background conflict among couples is one of the most important issues in the family and often causes wives to refer for therapy. one of the most important therapeutic approaches is narrative therapy, the efficacy of which is investigated in this paper. objectives the aim of t...

background treatment for psychological disorders is generally based on signs and symptoms, and research in this area has shown that major depression has become one of the most significant psychiatric disorders of the last decade. objectives this study was conducted to compare the effects of schema therapy and cognitive group therapy on women with depression who were engaging in high-risk sexual...

Causal consistency is a widely used weak model and there are plenty of research prototypes industrial deployments causally consistent distributed systems. However, none them consider Byzantine faults, except Byz-RCM proposed by Tseng et al. achieves causal in the client-server with \(3f + 1\) servers where up to f may suffer but assumes that clients non-Byzantine. In this work, we present Byz-G...

Abstract In the context of integrating modern information technology and new engineering, this paper first sets up alternative controller nodes data in whole blockchain network, which no longer requires administrators to maintain platform eliminates problem centralized trust crisis. Then are optimized through RP-PBFT consensus according technology, pack encrypt transaction based on an elliptic ...
