FIBPRO: Peer-to-peer data management and sharing cloud storage system based on blockchain

With the continuous and rapid development of cloud-based data services, the total volume of Internet data is experiencing explosive growth. Nevertheless, contemporary centralized cloud storage-oriented data service providers encounter significant challenges in fully satisfying the requirements for user data security, fine-grained access control, and consistently high-performance standards. In this paper, we propose and implement an efficient peer-to-peer data storage and sharing system to address the challenges faced by service providers. Our solution utilizes the modified EOSIO blockchain and the InterPlanetary File System (IPFS) distributed storage as the underlying data storage framework. We employ hybrid encryption to ensure the secrecy of the shared data of the users and also to facilitate multiple uses and persistent storage of the shared data of the users. Moreover, with the expansion of the blockchain component, we provide a flexible transaction information audit solution that helps to trace the source of malicious behavior and reduces the cost of using blockchain information. In system analysis and experimental evaluation, compared to traditional blockchain storage, FIBPRO has theoretically achieved a 98.76% reduction in on-chain storage consumption. In practical concurrency testing, it achieved a comprehensive performance of approximately 1300 TPS (transactions per second), with an average upload efficiency of about 2.31MB/s and a download rate of about 5.29MB/s. These results demonstrate the system’s availability and scalability.
