A Systematic Review of Blockchain Hardware Acceleration Architectures

The aim of this paper is to provide a systematic literature review of blockchain hardware acceleration. Blockchain technology has achieved significant attention in recent years particularly in the area of cryptocurrency however it is gaining popularity in other applications such as supply chain management and e-government. Based on a structured, systematic review of the relevant literature, we present a classification of the primary areas in blockchain technology that make use of heterogeneous hardware for accelerating certain blockchain functions. Based on these findings, we identify various research gaps and future exploratory directions that are anticipated to be of significant value both for academics and industry practitioners.
