Blockchain-based distributed file system security and privacy: A systematic mapping study

Abstract

Blockchain-based distributed file system is an emerging, decentralized technology that enhances blockchain for storing data and general-purpose files off-chain. The platform integrates blockchain technology with the distributed file system to give users the ability to store data and content respectively on the technology which offers distributed access to data safe and secure among a community of trusted or untrusted networks. This advancement is gaining traction in researchers, with a growing number of research papers and applications being built based on this technology. However, the combination raises doubt on the security and privacy issues of the system. The blockchain-based distributed file system also is still young, unstructured, and in its early stages of research. Thus, a systematic mapping study was carried out and 23 primary studies were identified. Extraction of data is then carried out based on their research type and contribution type facets to gain a wide overview of blockchain and distributed file systems focusing on security and privacy.
