Abstract

The new Blockchain technology provides a new format for storing information in a database, and the transaction processing method in this technology allows for a high level of decentralization. Therefore, the application of this technology in different fields, due to the distributed and decentralized control of data, makes possible safe, scalable and efficient management of resources. A Blockchain can be thought of as a sequence of connected data blocks, each of which depends on the previous block and forms a continuous chain-like data structure. In this article, after a brief introduction to the Blockchain, the framework and components of this technology and its unique features besides its consensus algorithms are described. Due to the features of Blockchain, this technology is used in various fields such as IoT, Big Data, cloud computing, identity management, smart contracts, supply chains, medical informatics and communications. In this article, we try to introduce these applications and review related research in this field. Also, considering the security vulnerabilities of the Blockchain as well as its operational limitations, various challenges to the implementation of this technology are reviewed. Since transaction processing rate or throughput of Blockchain systems are relatively low comparing to other databases, and on the other hand, transaction latency or response time in this technology is relatively high, improving the performance of the Blockchain is an important issue. Various solutions are proposed in this field, one of which is the use of Blockchain databases such as Bigchain DB.
