Over the last years, extensive research has been done in the field of blockchain technology and there are a growing number of areas to which blockchain is being applied, creating broad knowledge in this field. Classifying the subfields and identifying new topics and research trends in the area of blockchain would be of significant help to researchers. The present study aims to review and categorize studies on blockchain technology, identify subfields, and achieve a coherent view of its research process. using bibliometric analyses. The data used in this research has been collected from 423 articles in the Scopus database. Then, the bibliographic coupling analysis and keyword co-occurrence have been performed.According to the findings of this study, researches on blockchain technology are divided into 5 clusters: 1. Computer systems, 2. Financial sciences, 3. Smart contracts, 4. Data management and authentication, and 5. Electronic cash. In recent years, topics such as machine learning, trust, deep learning, risk assessment, edge computing, Ethereum, and consensus have drawn the attention of the research community. This research provides a comprehensive classification of the main concepts and topics discussed in blockchain-related research, designated to help researchers in this field choose a line of research.

While electronic government could help the development of the country and also boost the security and decrease the corruption, but, at the same time it can prepare an infrastructure for other types of crimes and facilitate some type of corruptions. This paper attempts to identify and prioritize the security features and necessities that Government Service Bus(GSB) should have as an electronic government infrastructure. Afterwards vast literature review and interview with the designers and users of this system, the security requirements of different stakeholders were identified. After that by content analysis, these requirements were refined and codified. Three categories of requirements are strategic,, technical and legal or national security requirements. Then adopting Kano model and quality function deployment (QFD) the requirements were processed and prioritized. The results and findings of this research showed that GSB is better than other systems like peer to peer(P2P) and physical document interchange and outperformed them in all dimensions. The main concern of all of respondents and experts were in the area of security. They are unanimous that security framework and standards of the system should be developed and implemented. This also emphasizes the importance of this type of researches.
