Emerging Trends in Blockchain Technology and Applications

At present times, Blockchain technology is gaining more attraction with every passing day, as it has revolutionized the traditional trade due to its distributed ledger feature, every record in this ledger is secured by rules of cryptography which makes it more secure and tamper-free. This naturally led to the emergence of various types of cryptocurrency, such as Bitcoin, which builds on a technology commonly known as Blockchain. The rapid evolution of research on Blockchain calls for more research studies for investigating and analyzing the current knowledge in this field through a systematic technical study that shows the impact and significance of the related literature since the inception of the technology in 2013. From this point, in this paper, a state-of-the-art review is conducted on the most influential articles, conference papers, and review papers related to Blockchain published from 2013 to 2020 and indexed by the Web of Science Core CollectionTM (WoS) world’s literature database. To attain the desired objective, after presenting an inevitable, brief overview of Blockchain technology, the collected papers have closely been analyzed along seven key research questions. Subsequently, vital valuable findings, such as the top 10 influential papers, yearly publications and citation trends, the favorite publication venues, the hottest research areas, and the most supportive funding bodies are reported, which may offer several implications about the status quo and emerging trends and frontiers of Blockchain, to guide towards establishing a baseline for both fresh and experienced researchers and practitioners before initiating a future research project on Blockchain. Furthermore, a rigorous discussion is provided on Blockchain application in diversified domains, along with different versatile use cases. Lastly, a brief insight is presented into open challenges and potential future advancements in the field of Blockchain. Summing up, this paper is meant to assist newbies in exploring and designing new Blockchain solutions, bearing in mind existing demands and challenges.To get more news about blockchain field survey, you can visit wikifx.com official website.

Since the digital cryptocurrency, so-called Bitcoin, has been innovated in 2008 (Nakamoto, 2008), a diverse range of researchers and practitioners have paid considerable interest to Blockchain technology. Blockchain technology acts as the ledger used for taking records of all Bitcoin transactions as seen in Bitcoin applications (Fanning and Centers, 2016). The records of transactions are made justly public within the Blockchain framework, putting the aspect of privacy to the test. Everyone within the modern business technology environment would be able to ascertain the details of transactions because the current traditional banking system can maintain this form of privacy through confidential record-keeping.
2. Blockchain overview
In principle, Blockchain can be defined as a digitalized public ledger, in which all digital transactions would be recorded as a data structure “Completed Transaction Blocks” or in chronological order, and this is stored across a network in a distributed manner.
3. Research methodology
First, we present the motives behind this study and the research questions derived from such motives. Second, we describe a number of required consecutive steps that we followed to identify relevant studies. The methodology identifies detailed steps to collect the initial set of articles as well as the inclusion and exclusion criteria to obtain a filtered set of studies.
4. Descriptive analysis
To find satisfactory answers to the RQs presented in Section 3.1, a descriptive analysis was conducted after retrieving and selecting papers.
