Systematic Literature Review of Blockchain Applications: Smart Contracts

Abstract

Blockchain technology has received extensive attention recently, but still a large of technical challenges such as scalability and security. This paper helps to find where recent studies have been focused on and offers a broad perspective relating blockchain applications and smart contracts, their main problems and corresponding solutions and will help to specify gaps and future research. The study extracted 292 articles from top Digital Libraries such as IEEE, ACM, Science Direct and Springer. After a detailed review process only 28 publications were considered based on defined inclusion and exclusion criteria.
