Research Area:  Blockchain Technology
With the increase in connectivity, the popularization of cloud services, and the rise of the Internet of Things (IoT), decentralized approaches for trust management are gaining momentum. Since blockchain technologies provide a distributed ledger, they are receiving massive attention from the research community in different application fields. However, this technology does not provide with cybersecurity by itself. Thus, this survey aims to provide with a comprehensive review of techniques and elements that have been proposed to achieve cybersecurity in blockchain-based systems. The analysis is intended to target area researchers, cybersecurity specialists and blockchain developers. For this purpose, we analyze 272 papers from 2013 to 2020 and 128 industrial applications. We summarize the lessons learned and identify several matters to foster further research in this area.
