Blockchain Technology: Characteristics, Security and Privacy; Issues and Solutions

The Blockchain technology is the most widely used and known of the cybersecurity techniques in recent years. This technology contained a lot of techniques, which are economic models, mathematics, cryptography, and algorithms. It is vital for several reasons, which are solving the synchronization problem and does not require the presence of more than two parties. In this paper, we survey Blockchain technology in terms of the consensus algorithms, the architecture, and the main features of this technology. This survey is constructed by explaining the importance of the privacy and security of the blockchain, issues, and some solutions if possible exists. This paper contributes to supporting the researchers who want to study the Blockchain Technology in terms of concept, applications, "security and privacy issues and solutions", and work mechanism of it.
