Although CASE tools and other technologies were coming up, computer programming had still not become a real engineering product for many reasons. This resulted in high software creation costs and significant failure rates. The next revolutionary thing came up in when the US government released internet technology to the world.
Until then, the internet was available to the US Defense personnel, Defense agencies, and some major universities. The Internet started a revolution of information technology. It was a problem created by programmers. In those days, a computer program had to be short and crisp, as computer memory was a major concern.
As a result, programmers had to compress the four-digit year to two digits, which was alright in the 80s and 90s until , but as comes, the two-digit year which would become 00 will screw up the programs. That was a real shock wave among the computer corporations, government, and financial institutions. They spent a substantial amount of money redesigning programs. This presented many opportunities for Asian immigrants especially Indians to come to the United States to work on the Y2K, leading to the first wave of IT people coming to the US and the Western world.
The real revolution of the Internet started at the beginning of Y2K surplus funds were available, and a lot of companies promised to produce nice products, but nothing much happened. However, the ingenuity of people prevailed. From , during the last 18 years, the internet has reached every corner of the world.
Today, there are more than four billion people connected to the internet. The Internet was able to function by the integration of information technology, telecommunication technology, and software engineering. The infrastructure was built everywhere so that TCP data transfer was never a problem for the programmers. Read: Lure of Bitcoins: Greed blinds even the wise to risks February 24, The rest of the edifice was much easier to be built. Today, every conceivable application has already been migrated from the legacy system to the internet.
However, the internet is not very reliable, secure, safe or protected. With the advent of more computer applications, and the opening of the internet, data security problems became a real challenge. Computer privacy and data security have also entered the realms of espionage. Russians could log into American computer systems and influence the US elections. To resolve this problem, we must design new innovative technologies. Emerging technologies are promising to be a major solution provider in this field.
The most promising among emerging technologies is blockchain. The concept was originally proposed through a white paper in , it is implemented for the first time in by Satoshi Nakamoto. Bitcoin is a blockchain based development platform to mine cryptocurrency floated by him and his associates. It enabled Bitcoin system to transfer funds between registered users.
Only sovereign countries are authorized to issue currencies but these bitcoin founders who believe in less governments created the first cryptocurrency, the popular bitcoin brand. As a result, undisclosed funds from various individuals and corporations went into cryptocurrencies like Bitcoin. The design and development of Bitcoin is done using blockchain. It is one of the most secure internet systems today.
For example, in the early days of the internet, email facility was not standardized. As a result, one could not communicate with another with a different email system. But later, a standard called SMTP Simple Mail Transfer Protocol was designed, which standardized all protocols within the email system, and enabled inter-communication between different email systems.
Peer-to-peer communication is a new concept in information technology. In the past, all IT devices were connected to a central processing system, a central computer, and everything else was connected to it. All information was stored in this central computer.
In the current internet system, this central computer is distributed all over the world. In the peer-to-peer communication architecture, there is no central computer. Each computer node is equal to another node and is connected to each other on an equal status basis. This is accomplished with the help of cryptographically accessible data structures. The data in the blockchain is transmitted cryptographically, to circumvent security and privacy concerns, i. In addition to that, there is a private key and a public key to access any data in blockchain technology.
An interesting feature of blockchain is that it is an open-source technology. Nobody is centrally controlled. There is a group of people who provide open-source programming code, available to everybody. Anyone can participate and contribute to the design and development, which will be evaluated and accepted.
The two keys are each about bit long in alphanumeric characters. While the private key is safe for individual usage and need not be disclosed to anybody unless they are accessing the transaction, the public key is for the system to distribute the data across the network. Thus, blockchain is very robust in terms of data transmission and data recording.
Another aspect of blockchain technology is that data is written in the form of a block. The physical data is first transcribed and then converted cryptographically. The key, date, and timestamp of the record are also created and stored cryptographically. So, a record contains all this information, and the next record refers to this record, and so on, a chain of records is systematically created. There cannot be any record added in between or deleted.
This chained record of blocks together forms a ledger, which is open and available in the network for everybody to use. Anybody who has access to this network can view it but will not know who this record belongs to or what information it contains, as the recording is cryptographic. Only the owner of that device or node can interpret what his data is. Bitcoin is essentially for financial transactions only. So, Bitcoin is nothing but a speculative currency. Despite its instability, many people who want to circumvent government control and knowledge about their funding, are fascinated with Bitcoin.
Today, there are more than 10, cryptocurrencies in the marketplace. Of late there is another company called Ethereum, whose principles also worked on Bitcoin Foundation, which also came up with the similar framework. Their framework can be used not only for financial transactions but also asset-based transactions. Any asset-based online system can be developed using Ethereum. Again, Ethereum and Bitcoin, are essentially platforms. Thus, Ethereum, which is also open source, has become the second most popular platform among the blockchain developers now.
As peer-to-peer architecture is not ideal for all kinds of data processing needs on the internet, migrating and transferring all existing applications to the blockchain is a real challenge. So, a third group under the leadership of Unix, Linux, and IBM came out with a new open-source framework called the Hyperledger Fabric.
Hyperledger Fabric is a foundation framework to be used for developing applications rapidly. It provides a virtual cloud computing environment with tools for data analysis, database design, screen design, logic design, etc. Earlier, a technology called the client-server model was used, in which a client serves a group of users, without the need to know who the client and the server are.
In cloud computing, the computer can be used without the need to know its location. Cloud computing can also be customized for a specific application, called virtual cloud computing. It also allows database access. Normally, blockchain does not have an interface with outside programs.
Hence, we should apply the sub-sample test to investigate the mutual influences between these two-time series. Balcilar et al. The selection of the width is complex matter. A small width may not ensure the robustness of the results, and although the large width can enhance the correctness of the results, but it may decrease the times of scrolls.
We follow Pesaran and Timmermann in this regard who ascertain that this width cannot be less than 20 if the parameters in the VAR system are non-stable andthe separated small parts are scrolled from the start to the end of the entire time series.
We assume that the extent of the entire sample is L and the rolling-window width is w. Each sub-sample can obtain a Granger causality result through applying the RB -based modified- LR statistic. Next, we can obtain the outcomes of the sub-sample test. N b is the frequency of bootstrap repetitions. In this paper, we consider the monthly data from M7 to M1 to explore the Granger causal relationship between Bitcoin and oil prices, then evidence whether Bitcoin and oil are in the same boat.
As we have explained earlier, BP and OP may have certain relationships, which means that there may be interactions between the digital currency and international oil markets. We can observe that Bitcoin and oil are not always in the same boat. When Bitcoin first appeared, BP increased slightly due to the fact that there were few traders and no formal Bitcoin exchange existed at that time. President Barack H. The Syrian war and Cyprus crisis in led investors to be more willing to hold digital currencies, immediately after which, the rise in demand drove BP to soar.
Since the unstable situation in the Middle East during this period, there are certain restrictions on oil production, which has kept OP at a high level. In the second half of , the U. In addition, the U. The U. Thus, Bitcoin and oil are in the same boat during these periods. This dramatic growth trend does not continue and there is a sharp decrease in BP in , while OP has experienced a rise and then a decline.
Although the situation in the Middle East has deteriorated in , its impacts on OP are short-lived. However, the global trade wars, especially the Sino-U. Additionally, the increasing demand for Bitcoin as a hedging asset drives BP to soar.
Hence, Bitcoin and oil are not always in the same boat. An interest rate cut may decrease the value of the U. Thus, the U. Table 1 reports descriptive statistics. The kurtosis of BP is greater than 3, thereby this series is satisfying the conditions of leptokurtic distributions. Meanwhile, OP and USDX satisfy the identification criteria of platykurtic distributions, since the kurtosis is less than 3.
Therefore, it is not appropriate to employ the traditional Granger test. Then, we use the first differences of these three variables to construct the Granger causality test models, which can ensure the stationary of the time series. Notes: The number in parenthesis indicates the lag order which is selected based on the SIC.
The number in the brackets indicates the bandwidth which uses Bartlett Kernel as suggested by the Newey-West test The VAR system, based on Eq. We choose the optimal lag order of 2 based on the SIC. These findings are not consistent with the previous studies Panagiotidis et al. Notes: To calculate p -values using 10, bootstrap repetitions. The full-sample estimation in the bivariate VAR system assumes that the parameters are constant and there is only one Granger causality in the whole period.
We employ Sup-F, Ave-F and Exp-F tests Andrews, ; Andrews and Ploberger, to examine the parameter stability, and also use the L c statistics test Nyblom, ; Hansen, to examine whether the parameters follow a random walk process. The results of parameter stability test are highlighted in Table 4. Therefore, through the parameter stability test, we can conclude that there is a non-stable interrelationship between BP and OP, and the full-sample test is not suitable for this paper.
Subsequently, we apply the bootstrap sub-sample rolling-window Granger causality test to investigate the time-varying interaction between these two variables. Also, we choose the rolling-window width of months, 6 in order to ensure the accuracy of the Granger causal relationship analysis. Bootstrap p -values of rolling test statistic testing the null hypothesis that OP does not Granger cause BP. Bootstrap estimates of the sum of the rolling-window coefficients for the impact of OP on BP.
The slow recovery of the global economy has increased the demand for oil Hammou et al. The instability in the Middle East e. All of these cause OP to be at a high level during the period of M1—M There are three reasons that can explain the transmission mechanism from OP to BP. Firstly, the rise in OP may trigger inflation, reduce the real income of residents and the profit margins of companies, especially in oil-importing countries Salisu et al.
Then, the public confidence declines, which in turn stimulates them to hold hedging assets e. Thereby, the increasing demand for Bitcoin drives BP to rise. Secondly, the instability in the Middle East and the Cyprus crisis not only cause OP to increase, but also make the investor sentiment low.
They are more willing to purchase Bitcoin to avoid the risks of geopolitical events, which drives BP to soar Ciaian et al. Thirdly, BP is also denominated in U. Although the U. Also, the value of the U. On the basis of above explanations, the positive influence from OP to BP during the period of M1—M10 can be proved and rationalized.
From , oil has experienced a rise in its price. Federal Reserve Board has announced that it would keep its Federal Funds Rate unchanged, causing the dollar to depreciate. The OPEC has agreed to cut the production in its member states, also the geopolitical events e. Although other events, such as the Brexit and the U. Trump v. Hillary D. Clinton , lead OP to fluctuate slightly, the overall upward trend is unchanged. We can explain the rise in BP caused by OP in four ways.
Firstly, the high OP may trigger inflation, reduce the real income of residents and the profit margins of companies, as well as the public confidence, especially in oil-importing countries Salisu et al. Then, they are more willing to hold Bitcoin to avoid the risks of the high OP, which drives BP to increase.
Thirdly, the geopolitical events in the Middle East increase OP, and also reduce the consumer confidence and investor sentiment. Then, they tend to store assets with hedging ability to reduce losses, increasing the demand for Bitcoin the price of which is already on an upward trend, and then BP increases Ciaian et al.
Also, the Brexit and the U. However, the view that Bitcoin and oil are in the same boat cannot be supported by the negative influence of both variables on each other. There are three reasons to explain the rise in OP. Firstly, the Federal Reserve Board has signalled interest rate cuts, and the yen has experienced huge fluctuations against most G10 7 and some emerging markets e.
All of them lead investors to be more inclined to invest in another asset, such as the oil and its related products, which in turn drives OP to rise. Secondly, on December 1, , China and the U. As a result, the economy is expected to be improved, which leads to the demand for oil and OP to further increase Hammou et al. Thirdly, due to the resolute implementation of production reduction agreements by major oil-producing countries, such as Saudi Arabia and Russia, oil supply has continued to decline, which causes OP to rise especially during the period of M12—M1.
Nevertheless, BP does not move in the same direction as OP to be helpful in avoiding the risks, and it can be explained from three aspects. To begin with, the Bitcoin bubble bursts in , and since then BP decreases sharply Li et al. This burst is mainly caused by the massive sell-off of Bitcoin asset in Mt. Gox, a bitcoin exchange based in Japan, and the subsequent herd behaviour 8 of investors, as well as government policy constraints e.
Securities and Exchange Commission has hinted at strengthening supervision and crackdown on unregistered online digital asset trading platforms. Additionally, the economy was expected to be improved, as a result there was a positive reinforcement for public and countries to purchase more oil but which decreases the demand for Bitcoin to avoid the risks of trade policy uncertainty Ciaian et al.
Furthermore, the rise in OP and the sharp decline in BP make the public less willing to hold Bitcoin, since it is not as valuable as oil and its related products. Hence, we can argue that these reasons provide sufficient justification for the negative influence from OP to BP during the period of M12—M1. After the outbreak of the Cyprus crisis, the public was in danger and they rushed to exchange their currencies for Bitcoin to avoid policy risks. Also, Bitcoin was increasingly recognized by investors around the world, especially after Germany officially admitted the legal and tax status of Bitcoin on August 19, Therefore we can say, the rising BP attracts more investors to invest in the Bitcoin market, which leads it to further increase during the periods of M12—M1.
The public also considers that Bitcoin has more investment prospects than oil, and they seem more willing to hold Bitcoin, which causes the oil demand and OP to decrease during this period. Then, the whole of society has been brought to a high degree of uncertainty, which has continued to put downward pressure on OP.
Bootstrap p -values of rolling test statistic testing the null hypothesis that BP does not Granger cause OP. Bootstrap estimates of the sum of the rolling-window coefficients for the impact of BP on OP. To sum up, the results of the bootstrap full-sample Granger causality test suggest that OP Granger causes BP, but the opposite is not significantly established. However, this result may not be comprehensive as the parameters in the VAR system are supposed to be stable.
The parameter stability tests prove that these two variables and the VAR system have sudden structural changes. Hence, in this paper, we apply the sub-sample test to explore the time-varying interrelationship between BP and OP. The empirical results evidence that there are both positive and negative influences from OP to BP. The positive effect indicates that Bitcoin can be viewed as an asset to avoid the risks of the high OP, also we can conclude that Bitcoin and oil are in the same boat since the value of Bitcoin will enhance if OP is high.
However, this view cannot be supported by the negative effects. The burst of the bubble makes Bitcoin incapacitated to hedge the risks of the high OP, which also highlights that there is a negative effect from OP to BP. In turn, BP has a negative influence on OP, revealing that oil has fewer investment prospects than Bitcoin during the few periods, which also indicates that high BP may threaten the demand for oil to invest and also OP.
As one of the core factors of the Fourth Industrial Revolution, Bitcoin has certain interactions with the global economy e. With the continuous progress of blockchain, Internet of Things, cloud computing, big data, artificial intelligence and other technologies, the transformation of society has increased dramatically.
Amongst all above mentioned technologies, cryptocurrencies have enormous potential to promote the reduction of international transaction fees and liquidity costs, and efficiently complete the movement of international wealth. Secondly, the improvement of the encryption technology and the reinforcement of the market supervision reduce the large fluctuations in the prices of cryptocurrencies, which makes them more acceptable to the public. Thereby, the view that Bitcoin can be considered as a hedging asset is becoming more reliable over time.
Thirdly, Bitcoin is the first Internet-scale open platform for value exchange. With blockchain technology supporting a wide range of value exchanges, it will inevitably bring about an explosion of tradable assets and spawn a greater industry wave which in conjunction with many innovative forces could promote the progress of human society. This paper explores the Granger causality between the Bitcoin and oil markets, in order to evidence whether or not Bitcoin and oil are in the same boat.
We perform the sub-sample test to investigate the mutual influence between BP and OP. The empirical results establish that there are both positive and negative influences from OP to BP. On the one hand, the positive effect indicates that Bitcoin can be considered as an asset to hedge the risks of the high OP, and we can also evidence that Bitcoin and oil are in the same boat.
On the other hand, the negative influences are not consistent with this view particularly when we see the negative effect from OP to BP, which can be explained by the burst of the Bitcoin bubble that has weakened its hedging ability. In addition, OP can be negatively affected by BP, pointing out that Bitcoin has more investment prospects than oil during several periods, which also reveals that the demand for oil to invest can be threatened by the high OP.
By analysing the time-varying interrelationship between BP and OP, we can conclude that Bitcoin and oil are in the same boat during certain periods, but this is not always the case. Clarifying the demand for Bitcoin to avoid the risks of the fluctuations in the oil market and the transmission mechanism between BP and OP can give lessons to investors and governments. On the one hand, OP can affect BP during certain periods.
Thus, investors can predict BP more accurately according to the fluctuations in OP and determine the amount to invest in the Bitcoin market. Also, they can consider Bitcoin as an asset in the portfolio, in order to diversify the risks and optimize their investment. More importantly, they should beware of the Bitcoin bubbles to avoid herd behaviour, reduce the losses and maintain their returns.
The government can also grasp the trend of BP based on OP, in order to implement related policies to prevent the Bitcoin bubbles or the plunge in BP which may reduce the public confidence and hinder the economic stability. By this way, relevant authorities can promote the healthy growth of the Bitcoin market. On the other hand, the increase in BP may lead OP to fall during a few periods. Hence, investors should decide the amount to invest in the oil market by considering the changes in BP, then they can obtain the optimal proportion of the portfolio and make it more profitable, in order to maximize their revenues.
In addition, oil-importing countries can grasp the trend of OP to increase or reduce the amount to import, then they can prevent inflation and minimize the costs. Others can avoid the overcapacity and maintain national wealth-income by adjusting production, especially for countries or regions where oil is the pillar industry e.
Also, the government is able to capture the fluctuations in the oil market, then, taking measures in advance to ensure the stable development of its energy system and national economy. In the future study, we will consider whether the Fourth Industrial Revolution can strengthen the hedging ability of Bitcoin. Also, the relationships between Bitcoin market and other energy or energy assets e. Ran Tao: Visualization, Investigation. Muhammad Umar : Writing, Reviewing and Editing.

From smart technology to cyber-physical systems, this age of technology seems to be more about pushing the limits of what digital technology can do throughout any possible field.
This is another thing it shares with the Digital Revolution; while the First Industrial Revolution was primarily for agriculture, both the Third and Fourth Industrial Revolutions are marked by technological advancements that can affect all industries in astonishing ways.
Certainly it wasn't difficult to call it the Fourth Industrial Revolution, considering there were three before it. So who decided that we had officially entered this new era? The person who coined it in its most relevant sense was Professor Klaus Schwab, the founder and executive chairman of the World Economic Forum, using it as the title of a book. Due to the high-tech nature of this age, it has also been referred to as Industry 4.
We're being told we're entering a Fourth Industrial Revolution, but the technology we use the most - our computers, our phones, our video game consoles - are part of the Digital Revolution. What burgeoning technology of Industry 4. Some of the more fascinating advancements that have already begun are virtual reality and artificial intelligence, or VR and AI.
In addition to the VR technology now available in video games, most notable with Oculus Go, it is now available for live television. BBC made it possible to watch the World Cup via virtual reality. A VR headset wasn't a necessary purchase, as it worked through smartphones and tablets as well. AI, meanwhile, has gone from a crazy futuristic thing in movies to something that autocompletes sentences and responds when you ask for Siri on your smartphone.
It has been casually integrated into your everyday technology, and will be integral to self-driving cars, a technological advancement that people have anticipated for years. It's an interesting quirk to contemporary society that AI went from something many feared to something that corporations gave a cute human name to so you'd feel comfortable asking it to help you shop.
In the Fourth Industrial Revolution, we've applied the internet to our outside lives. Report or a pizza from Domino's? Report Now you can stare at your computer or phone and track it from start to finish. The rapid advancements of technology's capabilities are affecting our warehouses, farms and hospitals as robotics gets more and more impressive.
It has, though, led to ethical questions about automation. In many ways, these advances can bring incredible innovations. Information is more convenient to find, and new strides are being made in productivity and efficiency in a number of industries. Communication is faster and more readily available around the world. Some have high hopes of using the technology from this era to improve the world in ways like limiting carbon emissions. There are lots of ways to look at the way technology is advancing and teeming with potential to better our earth.
However, we would be wearing some awfully rose-tinted glasses by saying that is all it can do. There is tremendous risk in all of this. There is fear that continued automation in so many industries could lead to millions finding themselves out of work. This is also arguably true about aspects of Industry 4. With all the data used to enhance and personalize AI, we have also become a far less private society.
This data can include personal information, and data breaches in large companies are more common than anyone would prefer.
