Technically cryptocurrencies often have Distributed Ledger Technology (DLT) and encryption based on infrastructure called blockchain that allows all nodes to verify the validity of a transaction. In terms of monetary theory, cryptocurrencies are currently the most developed virtual currencies that cannot perform all the basic functions of money such as the account, exchange and capital accumulation.The price of cryptocurrency is based on supply and demand, without an intervention of a central authority. Dynamics that affect the value of cryptocurrencies can be classified as internal and external variables. The internal dynamics of cryptocurrencies have been examined under the headings of economic infrastructure and technological infrastructure. External factors that are effective in determining the value are observed as popularity, security, volume, inflation, tax, crypto exchange accidents, perception, speculations / manipulations and news.

Blockchain is a developing innovation that can possibly reform the worldwide business and make a confided in relationship in a multi-party business organize. Square chain is one of the steadiest open records that jelly exchange data, and is hard to produce. Since, the data put away in square chain is not identified with by and by recognizable data, it has the attributes of namelessness. There are various reasonable use situations where blockchain has been applied. All through the instructive course, students get different sort of execution certificates, score transcripts, marksheets and so on which can turn into a critical ascribe for having admissions to new schools or new works. Because of hostile to manufacture mechanism, its simple to make fraud documents. So, as to take care of the issue of falsifying testaments, the advanced authentication framework dependent on blockchain innovation would be proposed. By the unmodifiable property of blockchain, the computerized authentication with hostile to fake and unquestionable status could be made. Through the unmodifiable properties of the blockchain, the framework not just improves the believability of different paper-based endorsements, yet additionally electronically decreases the misfortune dangers of different sorts of authentications.

Motivated by the large frequent price fluctuation and excessive volatility observed in the cryptocurrency market, this study adopts Bai and Perron’s structural change model by incorporating the trading volume and autoregressive variables to examine the number and location of change points in daily closing price, return and volatility proxied by the squared return of Cryptocurrency Index, Cryptocurrency Index 30, and the top 10 cryptocurrencies ranked according to market capitalisation. Results show that the structural changes occur very frequently for the price series, followed by squared return and return series which were consistently observed between December 2017 to April 2018. In addition, the results also reveal that the two cryptocurrency indices may not be beneficial as an indicator to reflect the whole cryptocurrency market for the entire studied period as these two indices do not display consistent structural change in contrast to the top 10 cryptocurrencies that might have significant implications for modelling the cryptocurrency data.

Blockchain is using in every aspect now because of its distributed ledger which is immutable. It provides the information to the users directly without any third party involvement. It mediates the transactions directly between the interacting parties securely. It also eliminates the friction and also the cost of current intermediaries. It is now using in healthcare system to provide the interoperability, security, decentralization and other. EMR is presently using in healthcare which has some issues. The issues in healthcare are patient cannot access the data of his/her own health information. So by this healthcare has issues like interoperability and delay in communication and some other. These issues can be solved by using the Blockchain in healthcare. By this Blockchain provide security by giving the patients to access their own data rather than provider.

Can cryptocurrency mining (crypto-mining) be a practical ad-free monetization approach for mobile app developers? We conducted a lab experiment and a user study with 228 real Android users to investigate different aspects of mobile crypto-mining. In particular, we show that mobile devices have computational resources to spare and that these can be utilized for crypto-mining with minimal impact on the mobile user experience. We also examined the profitability of mobile crypto-mining and its stability as compared to mobile advertising. In many cases, the profit of mining can exceed mobile advertising's. Most importantly, our study shows that the majority (72%) of the participants are willing to allow crypto-mining as means to replace ads to trade-off for benefits such as a better user experience.

The latest technologies are shifting how businesses capture, analyse and distribute data from the individual users' online activity. Therefore, this contribution critically reviews the latest developments on big data analytics and programmatic advertising. Moreover, it sheds light on the use of blockchain; as this distributed ledger technology provides secure, verified transactions among marketplace stakeholders. The findings suggest that the service providers are increasingly utilising data-driven technologies including programmatic advertising tools to target and re-target individuals online or on their mobile. However, individuals and organisations are becoming increasingly aware on data protection issues, as they often block marketers from tracking them and serving them ads. In conclusion, this contribution puts forward a theoretical framework that explains how, why, where and when practitioners are capturing, analysing and distributing data. In sum, it implies that the data-driven technologies are facilitating the businesses' customer-centric marketing.

이 연구는 웹보메트릭스 빅데이터 기법을 활용한 암호화폐 온라인 영향력을 조사했다. 구체적으로 2017년 12월 시가총액 톱50개 화폐를 대상으로 온라인연결망을 측정했다. 웹보메트릭스에 기반한 빅데이터 분석을 실시해 암호화폐 홈페이지와 연결된 외부링크를 조사하여 각 암호화폐의 대중적 인지도를 파악하고, 나아가 암호화폐들의 관계적 특성을 분석했다. 연구결과 bitcoin.org, bitcoin.com, steemit.com의 온라인 영향력이 가장 강한 것으로 나타났다. 특히 steemit.com이 외부로부터의 링크 수가 가장 많았으며 상호링크 관계망에서 중개자의 위치를 점하고 있었다. bitcoin.org은 외향중심성 값이 가장 높게 나타나 적극적인 정보전송자로 자리매김하고 있는 반면 bitcoin.com은 내향중심성에서 1등을 차지하면서 권위적 정보허브로서 기능하고 있음을 발견했다. 나아가 사회연결망 지표와 와이스(Weiss) 평가점수와의 통계적 상관성을 발견하여 빅데이터 분석이 시장 예측도 가능하다는 것을 시사한다. 암호화폐를 둘러싼 정부규제가 계량화된 데이터 없이 주관적 비평과 정성적 측면에서 접근되면서 논란이 있는 가운데, 이 논문은 암호화폐의 현황을 웹보메트릭스 방법으로 측정하여 정책지원의 과학적 수단을 제공한다.This study explored presence and influence of cryptocurrencies on the web. A network of top 50 cryptocurrencies in terms of market capitalization was mapped on December 12, 2017. Webometric analytics was conducted to examine online presence and influence of each cryptocurrency as well as the relations between cryptocurrencies by tracing the external links from each site. The results suggest that bitcoin.org, bitcoin.com and steemit.com were the most influential sites based on the number of hit counts. Interestingly, steemit.com received the largest amount of links from other sites and bridged the sites of the other cryptocurrencies in the network. It is noteworthy that bitcoin.org with the highest outdegree centrality played a role as an active informant while bitcoin.com with the highest indegree centrality was a hub in the network. This study also found positive correlations between the results of Weiss ratings and key social network analysis indicators, including hit counts, Betweeness centrality, Out2Step, OutARD, InARD and 2StepBet. The result implies that webometric analytics is useful to predict a market. This data-driven approach to online influence and presence of cryptocurrencies is valuable to policy-makers who continue to debate about the societal impact and the regulations of cryptocurrencies.

All bettors, including the ???House,??? experience losing streaks and winning streaks. The House typically has a ???bankroll??? that is orders of magnitude larger than that of any individual bettor, and so can survive losing streaks without going bankrupt, thus remaining solvent long enough to win. Online wagering provides a new twist to this age-old scenario. We use elementary mathematical principles together with the idea of a virtual infinite sample size and the elimination of time as a constraint to develop a fail-proof system that generates the greatest possible exponential growth of capital. Let ?? (stake) be the amount you wish to invest or wager each time and ?? (return) be your return or odds on a proposition. Let n (number) be the sum of consecutive loosing investments or number of times you can loose on an identical proposition before depleting a specified amount of investment capital called ?? ( bankroll). The resultant equation, which I call the: Investment Betters Algorithm (click on thesis to view)
\nprovides the answer to remaining solvent long enough to outlast the irrationality of the simulated online ??? wagers open market ??? through a geometric progression. The augmented bankroll ?? , calculated slightly higher than the typical sum of the Geometric Series, can serve as a safeguard to capital ruin by it extreme disproportion to. Consider further the expected value of even money propositions, a virtual infinite sample size, and the elimination of time as a constraint and you have a no fail system to generate the greatest progressive exponential growth of capital. Current problems associated with financial return optimization algorithms are identified and discussed. Probable solutions to those problems are also prescribed along with improvements to diversified portfolio design.
