Insights into Blockchain-Based Decentralized Storage Networks: Security Analysis

Abstract

The spectacular development of information technology (IT) led to massive data proliferation. Management systems such as big servers and cloud computing failed to satisfy current requirements engendered by this tricky challenge. The most remarkable shortcomings concern bottlenecks that are the principal causes of security attacks (Denial of Service attacks, confidentiality, integrity, and availability harms) and resource constraints (scarce storage space and computational efficiency). The emergence of decentralized systems (blockchain and decentralized storage) opens new perspectives in handling security and privacy, scalability, and storage shortcomings. The aim of this paper is to conduct a review on works built by the cooperation of the distributed ledger and decentralized storage. After, we define the main concepts, present works made in this field, and analyze recent papers investigated. The discussion demonstrates the relevance of the emerging technology blockchain-based decentralized storage networks in enhancing security and privacy aspects of stored data. In order to sharpen this creative approach, future directions are explored.
