ABSTRACT = { Internet of Everything (IoE) has emerged as a promising paradigm for 
the purpose of connecting and exchanging data among physical objects and 
humans over the Internet, and it can be widely applied in the fields of industry, 
transportation, commerce, and education. Recently, the emergence of 6G-enabled 
cybertwin network architecture provides the technical and theoretical foundation 
for the realization of IoE paradigm. However, the IoE has three open issues in the 
6G-enabled cybertwin architecture, i.e., data authenticity, data storage and node 
reliability. To address these issues, we propose a blockchain-based decentralized 
reputation management system (BC-DRMS) for IoE in 6G-enabled Cybertwin 
architecture. In the proposed BC-DRMS, the traffic data collected from end nodes 
is stored on the blockchain and the decentralized file system, i.e., InterPlanetary 
File System (IPFS), to resist data tampering, and then the data is further processed 
by the edge clouds and core clouds to provide services to users. Also, a multi-level 
reputation evaluation scheme is designed to compute the reputation scores of IoE 
nodes to prevent malicious node attacks. The experiment results and analysis 
demonstrate that, compared to the traditional centralized reputation management 
systems (CRMS), the proposed BC-DRMS cannot only address the issues of data 
authenticity and storage, but also provides high reliability for IoE in 6G-enabled 
cybertwin architecture.},
