Abstract:: In the era of big data, either enterprises or personal users have more demand for data storage, and the flexible expansion characteristics of the distributed storage architecture have become an ideal storage solution. Based on the needs of users, this paper proposes a decentralized storage mechanism and adopts the P2P storage architecture of blockchain. This paper uses a simulation test to simulate the data storage process in the system. The purpose of this paper is to explore how factors such as file size, storage system design differences, and trust scoring mechanism design affect system storage performance. This paper adds a trust evaluation model to the system to reduce the failure probability caused by malicious nodes when the system accesses data. Moreover, it can enhance system performance and user experience as well . Furthermore, combined with the P2P storage characteristics of the blockchain, cloud vendors can provide this storage service in the sharing economy. The academic contribution of this paper is to adopt the blockchain P2P storage architecture and design the trust evaluation model to enhance the storage performance of the system. Practical contribution is to find variables that affect system performance through experimental design and provide cloud vendors with reference to system design for different designs and results.
