Currently, blockchain as a core technology of many application has received attention. It is actually a distributed database which maintains a data record list that continuously grows. The secured distributed key behind of blockchain have the potential to address many online transactional applications such as Bitcoin. Due to increasing the usage of blockchain technology, especially in security- based applications, in this paper, we provide an analysis of security issues in the blockchain. Furthermore, we will discuss some use cases as well as challenges in this area
