ABSTRACT
Bitcoin is widely represented in the popular press, but far less so in serious academic inquiry. Researchers have
analyzed Bitcoin from various discipline-specific perspectives using their own sets of theories and jargon. Yet
cross-disciplinary research has been muddled by the inaccurate interpretation of terminology across fields of
research. This results in polarized assessments. In an effort to examine the Bitcoin phenomenon in a more
holistic and multidisciplinary manner, this paper compares Bitcoin with another innovative technology the
World Wide Web as first envisioned by Tim Berners-Lee. By exploring the early development of the World
Wide Web, we seek to compare and contrast its development with that of Bitcoin and blockchain technology.
The goal of this study is to show similarities and differences in their historic development, in order to identify key
success factors related to the adoption of these technologies. Through identification of these factors we seek to
guide both academics and practitioners towards fruitful avenues of research and development.
Key Words: Bitcoin, blockchain, World Wide Web, WWW, internet, technology, technology acceptance
1. INTRODUCTION
Bitcoin is a new technology, with a novel combination of features and attributes, and yet technological
developments of similar magnitude and potential have happened with a certain regularity. It may thus prove
beneficial to analyze the phenomenon of Bitcoin in the context of previous developments of a similar qualitative
nature. The particular historical development that we feel shares many of the characteristics of Bitcoin is that of
the World Wide Web, developed and pioneered by Tim Berners-Lee back in the early 1990s. We are not the first
researchers to observe these similarities. Dr. Jerry Brito, formerly of the Mercatus Center at George Mason
University in his testimony before the New Jersey Assembly's Financial Institutions and Insurance Committee
made this analogy (Brito, 2015). In this paper we will explore the historical parallels in much greater detail in
order to determine how these parallels may aid us in understanding the Bitcoin phenomena.
2. WORLD WIDE WEB FORMATION
In March 1989, Berners-Lee submitted the first official proposal to develop the World Wide Web (at the time
simply referred to as "Mesh"), to his bosses at CERN - The European Organization for Nuclear Research -
where he was a contractor working on documentation systems (Berners-Lee, 1989). His goal was conceptually
simple: create a platform independent, hypertext based system that would enable all the world’s scientific
articles to be linked to one another (Berners-Lee, 1998). He desired a system in which repetitive questions could
be replaced with a FAQ (or Frequently Asked Questions) page so as to avoid redundancy and increase
efficiency in the distribution of information (Berners-Lee, 2015). Yet the World Wide Web (hereafter WWW) was
not entirely new. Rather, like most successful technological developments, Berners-Lee’s creation, to
paraphrase Newton, “rested on the shoulders of giants".
The key technologies underlying the proposed WWW, the Internet and its TCP/IP protocols, and the idea of
hypertext, were by that time decades old. The Internet protocols were developed by Vinton Cerf, Robert Kahn,
and others in 1970s (Cerf & Kahn, 1974), and have been used for information exchange over higher-level
protocols (such as FTP, news, email) for many years. The idea of hypertext, that of having links from within text
to other documents, is even older, with the basic idea in computer context described by Nelson (1965), and
presaged even earlier by Bush (1945) in the context of microfilm, and used in many software document
organization systems since. The actual network that carried Berners-Lee’s WWW creation had been originally
developed as a project by the US Defense Department in the 1960s (Hafner, 1998).
The key innovation of the WWW was to develop protocols to allow for easy hypertext linking between disparate
systems over arbitrary distances, relying on the Internet as a transport mechanism. Though there were several
hypertext systems in existence, Berners-Lee was unsuccessful in convincing any of them to add Internet
functionality. Instead, similar to old-fashioned CD-ROM based encyclopedias, these “walled garden” hypertext
Volume X Number 2 2015 ISSN 2326-3636
Journal of Strategic and International Studies
83
systems existed solely within their own environment. Unlike Berners-Lee, these hypertext system creators
lacked the vision to understand the potential for creating value if hyperlinks could be made to data housed
anywhere in the world (Berners-Lee, 1996). Through a process of “technological grafting” (Lennon, 2008),
Berners-Lee was able to integrate his new hypertext protocols onto the existing Internet hardware and software
technologies and incorporate their functionality to create a novel and extraordinarily valuable method of sharing
information in the form of web pages.
The protocols and specifications that enabled these web pages HTTP (HyperText Transfer Protocol), HTML
(HyperText Markup Language), and the URI (Uniform Resource Identifier) were developed by Berners-Lee in
the space of several months in 1990 on the NeXT platform. This code for the browser and the server became
the de-facto implementation standard. HTTP specified a protocol for orderly request/response data interchange
over the Internet; HTML was a simplified version of the existing SGML (Standard Generalized Markup
Language) specification (ISO, 1986), which allowed for an easy, portable way to define document structure; and
the URI specification defined how a pointer to external resources is to be interpreted and followed (Berners-Lee,
Cailliau, Groff, & Pollermann, 1992).
While these various software terms and acronyms may seem arcane, these components are in fact all relatively
straightforward, with minimal complexity. For instance, basic HTML (hypertext markup language) is quite easy to
learn, and can be written with a plain text editor. Any computer user can readily make a basic web page. While
separately they may be conceptually simple, together these technologies form a sophisticated system of great
value.
Combined, all of these components allow for a portable, "universal" way to link disparate systems together.
Where other systems for information organization failed to take off in a meaningful way, the WWW succeeded,
for a number of reasons. In addition to its simplicity, it has a deliberately decentralized nature. Nobody needs to
ask permission to create a webpage and link to other websites. There is no central database or authority which
needed to be updated or maintained. It was a lack of such a central database that gave rise to Internet search
engines like Google (Brin & Page, 1998). Yet another reason was its ability to link multiple sources of information
across the world with the help of the Internet, and its embrace of previously existing protocols as part of the URI
specification.
2.1. OPEN SOURCE KEY TO DISRUPTION
Another important move by Berners-Lee was the deliberate choice of open licensing the protocols and the
software implementation thereof was released by CERN into the public domain, at his request (Berners-Lee,
2015). A competing protocol for information linking and organization, "Gopher", which was developed by the
University of Minnesota (Anklesaria et al., 1993), was also a product of the late 1980s, and by early 1990s when
the WWW was in its nascent stages, was relatively more established and widespread. One major reason why
Gopher was largely abandoned in favor of the WWW was the decision in early 1993 by the University of
Minnesota to charge licensing fees for the use of its implementation of the gopher server. This led to broad
concerns that the University might go after independent implementations as well, which in turn pushed people to
look for alternative technologies (Ward, 2006).
Learning from this experience, Berners-Lee petitioned for and received a declaration from CERN, allowing
anyone to use the Web software and protocols without any constraints. This caused the WWW to act as a
“disruptive technology” (Bower & Christensen, 1995) and enabled it to unseat Gopher as the predominant
technology. In 2000, the University of Minnesota backpedaled and released its gopher software under the
permissive share-alike GNU General Public License (GPL), but by that time, Gopher had turned into merely a
footnote in the annals of Internet history (Frana, 2004).
Despite its ascendency over its rival gopher, like other new technologies and products, the WWW initially had a
classic slow start. As a new product with a limited number of users and benefits, it had issues related to network
externalities (Liebowitz & Margolis, 1994) and the technology acceptance model (Venkatesh & Davis, 2000). The
value of the WWW to a potential new user depended on the amount of information accessible via the medium,
and how easy it was to access it. At the same time the usefulness of making information available via the Web
and making it easy to use depended on the number of users one could reach on the WWW.
An additional bottleneck was the fact that the initial implementation by Berners-Lee was on the NeXTStep
system, a computer platform that was relatively less widespread than the PC, Mac, and Unix systems at that

time. Through continuous efforts of Berners-Lee and his team to promote the WWW technology, port the
software to other systems, and, very importantly, through tapping the broader Internet community to help with
the project, via alt.hypertext and other newsgroups, adoption of the WWW technology gradually snowballed
(Ward, 2006).
2.2. ESTABLISHMENT OF WWW STANDARDS BODY
Several key events occurred which promoted the proliferation of the WWW. First, a number of third-party web
browsers for various platforms were created, among them NCSA Mosaic (Andreessen, 1993), the precursor to
the (in)famous Netscape, which later became one of the first dot-com era IPOs (Kelly, 2005). Since different
browsers could support different components of the Web protocols, and thus could potentially cause
fragmentation of the WWW ecosystem, in 1994 Berners-Lee started an independent standards body to maintain
and further develop the protocol specifications for common use. Known as the World Wide Web Consortium
(W3C), it exists to serve this function to this day (Giampietro, 2014).
Additionally, the growth of the WWW as a "universal" mechanism for information access, even in its early days,
caused disruption to several connectivity and information providers that existed at the time, such as those of
Prodigy and Compuserve (Fleming, 1995). These companies provided communication and access to their
subscribers, but rather than providing general-purpose Internet access, they created their own "walled gardens"
of information, via proprietary forums, message boards, messaging, and even e-commerce. As the Web grew,
these service providers started offering general purpose Internet connectivity, and over time their walled-garden
communities atrophied (Carlson, 2003). In response to this “disruptive technology” of the WWW, all of these
firms were forced to change their business models (Johnson, Christensen, & Kagermann, 2008)
3. BITCOIN FORMATION
The creation and development of Bitcoin mirror that of the WWW in a number of respects. Just like the Web,
Bitcoin had a multitude of precursors, relied on a unique combination of existing technologies, and succeeded
where others failed for many similar reasons.
On November 1, 2008, the cryptography mailing list received a post from one Satoshi Nakamoto, describing a
proposal for a new kind of digital currency one that would be decentralized, and would not rely on any central
authority or record-keeper a first for a digital currency (Nakamoto, 2008). Some discussion ensued, with most
being skeptical, but in early 2009, the first version of the Bitcoin software was released, and the Bitcoin
blockchain was born with the first (genesis) block containing the message "The Times 03/Jan/2009 Chancellor
on brink of second bailout for banks", which was a headline on the front page of the London Times on January 3,
2009 (Brito & Castillo, 2013). While the blockchain, the decentralized, public ledger is a novel concept, much like
the WWW Bitcoin relied on a number of existing technologies.
The actual cryptographic algorithms used in Bitcoin are US Government standards that had been developed
nearly a decade earlier. Bitcoin relies on the Elliptic Curve DSA as the transaction signing mechanism (Johnson,
Menezes, & Vanstone, 2001), the SHA-256 as the hash function (FIPS, 2002) and the Hashcash technique as
its proof of work mechanism (Back, 2002). Just as the innovation in the WWW is not hypertext, the innovation of
Bitcoin was not in novel cryptography.
Instead the true innovation was in an ingenious combination of existing tools and techniques, which together
defines the "blockchain protocol", which assured transaction authenticity, integrity, and ordering. Even the idea
itself was not new similar proposals (but not implementations) for virtual currencies had been discussed on
mailing lists (Cypherphunks, 1999) and written about (Dai, 1998) as far back as the late 1990s. Just like with
Berners-Lee and his integration of the hypertext related protocols onto existing Internet technologies,
Nakamoto’s genius was to “technology graft” (Lennon, 2008) these existing cryptographic technologies together
to form something unique, the blockchain public ledger and its system of record keeping and maintenance.
3.1. BITCOIN TECHNICAL ACHIEVEMENT: NO CENTRAL AUTHORITY
Nakamoto (2008)’s major technological contribution is to solve the "double spending problem" inherent in digital
currency (Jacobs, 2011), without relying on a central clearing house. With physical currency, giving someone a
unit of money automatically removes it from ones possession. With money usually having the property of being
difficult to reproduce, this maintains a limited supply of currency and thus maintains its value and purchasing

Journal of Strategic and International Studies
85
power. In an entirely digital currency scheme, where a currency unit is simply a string of bits, duplication of
currency becomes trivial, wherein you can give a copy of a currency unit to multiple parties. This would obviously
destroy any value the scheme might have as a currency (ECB, 2012).
One ready solution, first employed by a number of early electronic currency systems, such as DigiCash, eGold,
loom.cc, and others (Weiner, 1999) is to maintain a central database of who owns how many units of currency.
This replicates a traditional banking system in which both the spender and receiver must register with a central
third party system. When a spender sends a unit of currency to a receiver, the central authority will deduct the
unit from the source and add it to the target's account. Just like a traditional bank ledger, the central authority
must manage the debits and credits for all parties (Grinberg, 2011).
But the requirement for a central authority brings with it a number of problems, including the ability for the central
issuer to arbitrarily inflate the money supply (Brito & Castillo, 2013), and the dependence of the entire scheme
on the continual survival of the central authority (Grinberg, 2011). Nakamoto (2008) proposes an ingenious and
elegant solution to the "double spending problem" without the use of a centralized third party record keeper. By
putting together known cryptographic functions already widely used by the US government and adopted as a
standard by the US Commerce Department (Jacobs, 2011), he develops an algorithm which allows multiple
parties to use CPU power to agree on a unique sequence of events, and lock it in an auditable ledger, the
"blockchain" (Becker et al., 2013). This auditing process is automatically conducted by all participants in the
network who are running the Bitcoin software; agreement on new transaction sequencing is locked in by "bitcoin
mining", wherein processing power is used to "cast your vote" for your view of the timeline (Velde, 2013).
Crucially, the system also has a reward mechanism built in to encourage users to participate in the consensus
building process. A "miner" who successfully creates a new blockchain entry (a "block") that everyone can agree
upon, is rewarded with a quantity of newly-issued coins (Nakamoto, 2008). Additionally, the algorithm enforces a
geometrically declining rate of new bitcoin issuance, with a finite total number of units that will ever be issued,
thus offering a guarantee against future devaluation. This is in contrast to previously tried centralized systems,
where there was scant incentive for people to use the new currency, besides maybe whatever rewards the
central issuer proffered using its VC funding, and no guarantees whatsoever about inflation (Trautman, 2014).
Just like the World Wide Web, which allowed for decentralized, permissionless participation and innovation in
the information space (Thierer, 2014), the Bitcoin system allowed for the same in the currency space. Shortly
after the publication of the 2008 paper, Nakamoto released a software implementation of the system, licensed
under the liberal MIT software license which allows the use, modification, and distribution of the software with no
restrictions. As we saw earlier in the comparison between gopher and WWW, this licensing clarity was an
important component in encouraging community participation. Table 1 summaries the parallel success factors
between the WWW and Bitcoin.

3.2. CHALLENGES FOR BITCOIN
Similar to the WWW, Bitcoin had (and still has) issues of network externalities and technology adoption: why
should someone use bitcoins if no one else is using them? The mechanism of payment is useful to the buyer if
many sellers accept it, but only useful to the merchant to bother accepting if he can count on many buyers to use
it (Jacobs, 2011). The reward mechanisms mentioned earlier, along with its decentralized nature, have certainly
helped take Bitcoin further than any other digital currency has gone before, but only time will tell whether it will
achieve greater acceptance (Brito & Castillo, 2013; Grinberg, 2011; Velde, 2013).
The Bitcoin community has also followed the steps of Berners-Lee in setting up an organization to shepherd the
course of the digital currency ecosystem, fund development, interface with regulatory authorities, and try to avoid
fragmentation. Founded in September 2012, about four years after the creation of the Bitcoin system (amusingly
enough, about the same time between the creation of the WWW and the founding of the W3C), the foundation's
mission was to "standardize, protect and promote the use of Bitcoin" (Bitcoinfoundation.org, 2012)
Compared to the WWW, however, which was a nascent technology that initially presented relatively non-
controversial text based web pages, the acceptance of Bitcoin technology has been far more problematic. Given
its financial nature, critics ranging from Nobel Prize Winning Economists like Paul Krugman have denounced
Bitcoins as ‘Evil” (Krugman, 2013) and famed investors like Warren Buffet have condemned them as “a mirage”
(Hurlburt & Bojanova, 2014) as they perceive nefarious motives by the pseudonymous inventor Nakamoto. The
technology continues to be plagued by an image problem due to its use in illicit web based transactions
(Christin, 2013; Meiklejohn et al., 2013) and high profile failures of early trading exchanges like MT Gox in Tokyo
(Ron & Shamir, 2013; Villar, Knight, & Wolf, 2014). The proliferation of Bitcoin in comparison to the WWW has
also been hampered by the desire by regulators to create legal mechanisms for consumer protection as bitcoins
are integrated into the rest of the financial system (Kaplanov, 2012).
4. MARKET REACTIONS
The emergence of the World Wide Web, like that of many past technology innovations, has caught the attention
of businesses and investors. Since Netscape, the producer of the first mass-market browser, went public in the
summer of 1995, investment in Internet-related business soared over the next few years, as have market
valuations of technology companies. The NASDAQ Composite index, heavy in Internet technology firms, rose
rapidly from 1,005 on August 9, 1995, the date of Netscape's IPO, to a high of 5048 on March 10, 2000. From
then, it only took a few weeks for the prices to crash to 3321 on April 14, 2000.(Finance.Yahoo.com, 2015)
Market "bubbles" are by far not a new phenomenon, with the most famous example being the Dutch Tulip Mania,
back in the 1600s. According to the Minsky (1992)’s model of the credit cycle, a typical bubble goes through five
stages: displacement (technological disruption), boom (increase in investment), euphoria ("irrational
exuberance"), profit taking, and finally, panic. Many market manias, unlike the Tulip Bubble, happen in response
to actually productive new technological developments. While manias/bubbles result in an exciting speculative
roller coaster, and a certain amount of mal-investment, at the end of the day if the underlying technology is
useful, the built-up infrastructure ends up beneficial in the long run.
For instance, the British Canal Mania of the late 1700s/early 1800s was a response to the gradually improving
canal technology, which resulted in significant overinvestment in canal-building, causing plenty of financial
losses when the bubble popped (Dyos & Aldcroft, 1969). But at the end of the day, the country was left with

significantly improved transportation network. A similar pattern can be observed with the railway mania of the
mid-1800s in Britain (McCartney & Arnold, 2003) and that in the United states in the late 1800s (Shachmurove,
2011), which financed the build-out of railroad networks in the respective countries which were beneficial in the
long run. Likewise, the Florida land boom of the 1920s (Vanderblue, 1927) left a lot of real estate improvements
in its wake.
Similarly, the Internet boom (also known as the "dot-com bubble") that culminated in 2000 was no exception.
During the boom, companies invested heavily in Internet infrastructure, not least of which was investment in
long-range fiber optic connectivity (Odlyzko, 2010). The easy availability of low-cost bandwidth in subsequent
years was a boon to post-bubble companies seeking Internet capacity, and is oft cited as a driving facilitator for
globalization (Friedman, 2006).
The case of Bitcoin is similar to other technological investment bubbles. The Bitcoin system uses its own
currency unit, the eponymous bitcoin, to keep its ledger of accounts, so one must control some bitcoins in order
to have the privilege of making an entry in the distributed blockchain. With bitcoins being in limited supply by
design, investing in the units of currency is an obvious mechanism to speculate on the future prospects and
usefulness of the Bitcoin system.
Since Bitcoin's release in January 2009, bitcoins could be mined easily with consumer-grade CPUs, or had for
free for the asking on the discussion forums, for about a year. The watershed event in the history of bitcoin price
is the first exchange of bitcoins for something of value a trade of 10,000 bitcoins for two large pizzas
(Bitcointalk.org, 2010), although there were occasional trades in exchange for money some months earlier. In
October 2009, a bitcoin dealer posted an exchange rate of $1 for 1300 bitcoin (En.Bitcoin.it, 2010)..
The price history of bitcoin, as short as it is as of this writing, has already undergone three investment cycles.
Rising from nothing in January 2009, to $30 in June 2011, then back down to $2 by November 2011, completes
the first cycle. From there, rising to $250 in April 2013, and then dropping back down to $60 in short order within
the same month and meandering there until July 2013, marks the second cycle. Finally, rising from $60 in July
2013 to $1200 in December 2013, then falling to $230 by January 2015, marks our third cycle
(Bitcoincharts.com, 2015).
5. FUTURE OF BITCOIN
While these price gyrations are exciting and news-worthy, there are more important things afoot. A lot of real
infrastructure development has taken place, with a number of companies developing easier-to-use wallets,
merchant payment systems, and other innovations using the Bitcoin blockchain system. In 2014, more than
$300 million of VC funding has been invested in bitcoin-related companies, which is triple the amount invested in
2013 (Wong, 2014). Both merchant and user populations are gradually increasing, now including even such
household names as Dell and Microsoft (Hayes, 2014).
Alternative uses for the blockchain technology beyond just a remittance system are also under development,
with emerging academic research about it. Possible blockchain applications include the creation of smart
contracts (Buterin, 2014), the tracking of real property and securities (Rosenfeld, 2012), and crowd funding and
tracking of donations (Brito & Castillo, 2013). The potential applications are only starting to be appreciated.
The WWW has transformed the world in many ways that Berners-Lee did not foresee as he was developing the
Web. And even though many of the early dot-com firms, including Netscape, no longer exist even as a browser
the creation of the WWW truly was a “creative gale of destruction” (Schumpeter, 1934) which left in its wake
unimaginable products, services, and industries. Like Netscape, Bitcoin as a particular system/currency may or
may not survive for the long term. But like the WWW, the blockchain technology upon which Bitcoin is built, with
the ability to validate and timestamp events without relying on a central authority, is here to stay. It is a platform
for innovation whose history is only beginning.

... Sociotechnical imaginaries can be unifying visions, such as those that led from ubiquitous computing to IoT or those that led from the promise of the Internet to P2P software [1] to blockchain technology [42]. At the same time, proponents of a technology can have conflicting imaginaries; imaginaries branching [69] leads to technology forks as seen with the aftermaths of the Bitcoin scaling debate and the Ethereum DAO "hack". ...

Sociotechnical imaginaries are futures that people envision might be possible and desirable. They have a real impact on how systems are designed and what values they have embedded in their design. This article examines imaginaries about autonomous systems, decentralized systems, and decentralized autonomous systems. Through a discussion of the literature on autonomous and decentralized systems and how these imaginaries play out in the blockchain community based on my qualitative research, I demonstrate how decentralized autonomous systems are related to imaginaries about the organization of and the future of work. I identify three framings of imaginaries about autonomous systems: (1) autonomous technology as physical objects, (2) as mathematical rules, and (3) as artificial mangers. I also identify two sometimes conflicting framings of imaginaries about distributed and decentralized technology: these technologies as a new form of production and as freedom from control. These imaginaries intersect in decentralized autonomous systems, and I examine what they can tell us about the design and governance of such technologies. Lastly, I suggest ways of using the concept of imaginaries in participatory design.
... The fact that multiple cases of the theme "Financial disruption" were identified in this study reinforces this notion. Bitcoin has also been described as a "technological development of similar magnitude and potential" as the Internet [105]. However, media's role is complex as they "simultaneously may act as constructors of unique frames as well as a conduit for the public communiqués of others", as Callaghan and Schnell [106] phrases it. ...

Bitcoin, a decentralized cryptocurrency, has not only given rise to a wave of digital innovations but also stirred up considerable controversy. Some have hailed it as the most significant innovation since the Internet, while others have dismissed it as a Ponzi scheme that should be abandoned and forbidden. Regardless of these varying views, this is an innovation in need of scrutiny. In this paper we present a metastory of Bitcoin, based on an interpretative study of 737 news articles between 2011–2019. Through our analysis, we identified five narratives, including The Dark Side, The Bright Side, The Tulip Mania, The Idea, and The Normality. Our analysis demonstrates the interpretive flexibility of technology as influenced by ideologies, and we construct a theoretical model demonstrating media’s role as constructor and conduit. The metastory provides an institutional look at the broader interpretations of digital innovations as well as the multifaceted nature of digital innovations and how their interpretation evolve over time.

... The dynamics of cryptocurrencies since their creation seems to be similar to the DotCom phenomena in the 2000's (Ofek and Richardson, 2003). The success of cryptocurrencies is compared to the one of the World Wide Web as their share similar innovative features (Folkinshteyn et al., 2015) such as a lead-user 4 via a white paper, a technology that gathers several IT innovations, a nature combining ubiquity, open-source and decentralization, as well as the creation of new standards. These characteristics seems to be factors of bubbles creation similar to the DotCom ones . ...

The innovation introduced by cryptocurrencies and their underlying technology, blockchain, opens new avenues for research in finance. This PhD dissertation proposes three essays on cryptocurrencies, essays that use the theoretical framework of markets' informational efficiency.The first study aims to explain how the blockchain developed in informal communities is adopted and incorporated by organizations. This study uses the contractual and cognitive approaches of the organization theory in order to provide a theoretical framework for the blockchain technology. Through an illustrated literature review, a two-level analysis presents the potential uses of blockchain based on information access for participants. The objective of the second study is twofold. First, it raises the question about the true nature of Bitcoin. After comparing Bitcoin with currencies, gold and common stocks, we base our analysis on the assumption that cryptocurrencies may be assimilated to common stocks. Second, the financial performance (risk-adjusted return) of Bitcoin is empirically assessed using traditional models such as the CAPM and Fama-French three-factor models. We find that while integrating Bitcoin in portfolio highly improves its diversification, it also provides positive and significant risk-adjusted returns in the World, European and Asia-Pacific regions. The high Bitcoin's volatility and performance lead us naturally to focus on the speculative bubble aspect of cryptocurrencies, which is the focus of the third study. The analysis uses the PSY model of Phillips and Shi, 2018. Second, we focus the analysis on the main peak/burst of the cryptocurrency market at the end of 2017 using the Log Periodic Power Law (LPPL) model. The results suggest periods of bubbles implying a contagion effect between cryptocurrencies. The conceptual and empirical findings of this dissertation contribute to prior literature on cryptocurrencies on academic grounds. Our findings are also important for businesses and for investors that are interested in the cryptocurrency and blockchain potential as well as for policymakers in charge of their regulation.
... Cryptocurrencies such as bitcoins have been hailed as pioneering and potentially disruptive financial technologies. Bitcoin's blockchain technology allowed for a novel way of solving the "double spending problem" intrinsic to digital currencies, without relying on a central clearinghouse or trusted third party (Folkinshteyn et al. 2015;Böhme et al. 2015). Active support for Bitcoin may hence be understood as being fundamentally related to opportunities enabled from these differentiating technologies; making it an attractive substitute to traditional currencies for groups of users (Athey et al. 2016;Ermakova et al. 2017). ...

A vast digital ecosystem of entrepreneurship and exchange has sprung up with Bitcoin’s digital infrastructure at its core. We explore the worldwide spread of infrastructure necessary to maintain and grow Bitcoin as a system (Bitcoin nodes) and infrastructure enabling the use of bitcoins for everyday economic transactions (Bitcoin merchants). Specifically, we investigate the role of legal, criminal, financial, and social determinants of the adoption of Bitcoin infrastructure. We offer some support for the view that the adoption of cryptocurrency infrastructure is driven by perceived failings of traditional financial systems, in that the spread of Bitcoin infrastructure is associated with low trust in banks and the financial system among inhabitants of a region, and with the occurrence of country-level inflation crises. On the other hand, our findings also suggest that active support for Bitcoin is higher in locations with well-developed banking services. Finally, we find support for the view that bitcoin adoption is also partly driven by cryptocurrencies’ usefulness in engaging in illicit trade.

Although information technology has positively influenced operations in the Ghanaian financial sector, there is still a high operational cost in performing KYC procedures due to duplication of efforts during clients' onboarding. The decentralized nature of blockchains makes them ideal for addressing these challenges. In this paper, the blockchain maturity model was used to assess the maturity and readiness of Ghanaian banks to adopt blockchain technology for KYC processes. Using primary data obtained via questionnaires and interviews, the individual components of the blockchain maturity model were assessed. The results indicate that the network, hardware, and software components are at repeatable, defined, and managed stages, respectively, while the people component lags in the initial stage due to a lack of adequate staff training. Finally, security and privacy are at the defined stage, whereas policy and regulations are at the initial stage.

Digital currencies are rapidly evolving Internet currencies that have been increasingly attracting academic, governmental, banking, and business interest. This paper aims to present the commercial perspective towards the adoption of digital currencies as a means of daily transactions. Considering digital currencies as a pioneering technological innovation, this study proposes a research model that combines the innovation decision process model with the technology acceptance model, adding the construct of perceived security in order to investigate the factors that affect the actual use of digital currencies. The collected data from 254 respondents, derived from an online questionnaire-based survey addressed to commercial users, were further analyzed by using structural equation modeling. The findings of this research have significant implications for academics by bridging the gap in the literature about the factors affecting digital currencies’ commercial adoption and for practitioners concerning decision-making on their adoption and use. More specifically, this study stresses the role of perceived security and the fact that managers need to build their policies regarding transactions in digital currencies on the basis of security. Perceived usefulness was also found to be a significant factor, meaning that commercial users should be aware of the advantages of digital currencies regarding businesses. Moreover, compatibility with existing values and practices affects indirectly the actual use of digital currencies, implying that managers need to perceive that the use of digital currencies should be compatible with existing practices.

We perform a comprehensive measurement analysis of Silk Road, an anonymous, international online marketplace that operates as a Tor hidden service and uses Bitcoin as its exchange currency. We gather and analyze data over eight months between the end of 2011 and 2012, including daily crawls of the marketplace for nearly six months in 2012. We obtain a detailed picture of the type of goods sold on Silk Road, and of the revenues made both by sellers and Silk Road operators. Through examining over 24,400 separate items sold on the site, we show that Silk Road is overwhelmingly used as a market for controlled substances and narcotics, and that most items sold are available for less than three weeks. The majority of sellers disappears within roughly three months of their arrival, but a core of 112 sellers has been present throughout our measurement interval. We evaluate the total revenue made by all sellers, from public listings, to slightly over USD 1.2 million per month; this corresponds to about USD 92,000 per month in commissions for the Silk Road operators. We further show that the marketplace has been operating steadily, with daily sales and number of sellers overall increasing over our measurement interval. We discuss economic and policy implications of our analysis and results, including ethical considerations for future research in this area.

During 2013, the U.S. Treasury Department evoked the first use of the 2001 Patriot Act to exclude virtual currency provider Liberty Reserve from the U.S. financial system. This article will discuss: the regulation of virtual currencies; cybercrimes and payment systems; darknets, Tor and the “deep web”; Bitcoin; Liberty Reserve; Silk Road and Mt. Gox. Virtual currencies have quickly become a reality, gaining significant traction in a very short period of time, and are evolving rapidly. Virtual currencies present particularly difficult law enforcement challenges because of their: ability to transcend national borders in the fraction of a second; unique jurisdictional issues; and anonymity due to encryption. Due primarily to their anonymous characteristic, virtual currencies have been linked to numerous types of crimes, including facilitating marketplaces for: assassins; attacks on businesses; child exploitation (including pornography); corporate espionage; counterfeit currencies; drugs; fake IDs and passports; high yield investment schemes (Ponzi schemes and other financial frauds); sexual exploitation; stolen credit cards and credit card numbers; and weapons. Innovation in the pace of development of new currencies and technologies continue to create ongoing challenges for responsible users of technology and regulators alike. While technological advances create great opportunities to improve the health, living conditions, and general wellbeing of mankind; new technologies also create great challenges for nation states.

Bitcoin is a purely online virtual currency, unbacked by either physical commodities or sovereign obligation; instead, it relies on a combination of cryptographic protection and a peer-to-peer protocol for witnessing settlements. Consequently, Bitcoin has the unintuitive property that while the ownership of money is implicitly anonymous, its flow is globally visible. In this paper we explore this unique characteristic further, using heuristic clustering to group Bitcoin wallets based on evidence of shared authority, and then using re-identification attacks (i.e., empirical purchasing of goods and services) to classify the operators of those clusters. From this analysis, we characterize longitudinal changes in the Bitcoin market, the stresses these changes are placing on the system, and the challenges for those seeking to use Bitcoin for criminal or fraudulent purposes at scale.

Gullibility is the principal cause of bubbles. Investors and the general public get snared by a "beautiful illusion" and throw caution to the wind. Attempts to identify and control bubbles are complicated by the fact that the authorities who might naturally be expected to take action have often (especially in recent years) been among the most gullible, and were cheerleaders for the exuberant behavior. Hence what is needed is an objective measure of gullibility. This paper argues that it should be possible to develop such a measure. Examples demonstrate, contrary to the efficient market dogma, that in some manias, even top business and technology leaders fall prey to collective hallucinations and become irrational in objective terms. During the Internet bubble, for example large classes of them first became unable to comprehend compound interest, and then lost even the ability to do simple arithmetic, to the point of not being able to distinguish 2 from 10. This phenomenon, together with advances in analysis of social networks and related areas, points to possible ways to develop objective and quantitative tools for measuring gullibility and other aspects of human behavior implicated in bubbles. It cannot be expected to infallibly detect all destructive bubbles, and may trigger false alarms, but it ought to alert observers to periods where collective investment behavior is becoming irrational. The proposed gullibility index might help in developing realistic economic models. It should also assist in illuminating and guiding decision-making.

Why is it so difficult for established companies to pull off the new growth that business model innovation can bring? Here's why: They don't understand their current business model well enough to know if it would suit a new opportunity or hinder it, and they don't know how to build a new model when they need it. Drawing on their vast knowledge of disruptive innovation and experience in helping established companies capture game-changing opportunities, consultant Johnson, Harvard Business School professor Christensen, and SAP co-CEO Kagermann set out the tools that executives need to do both. Successful companies already operate according to a business model that can be broken down into four elements: a customer value proposition that fulfills an important job for the customer in a better way than competitors' offerings do; a profit formula that lays out how the company makes money delivering the value proposition; and the key resources and key processes needed to deliver that proposition. Game-changing opportunities deliver radically new customer value propositions: They fulfill a job to be done in a dramatically better way (as P&G did with its Swiffer mops), solve a problem that's never been solved before (as Apple did with its iPod and iTunes electronic entertainment delivery system), or serve an entirely unaddressed customer base (as Tata Motors is doing with its Nano - the $2,500 car aimed at Indian families who use scooters to get around). Capitalizing on such opportunities doesn't always require a new business model: P&G, for instance, didn't need a new one to lever-age its product innovation strengths to develop the Swiffer. A new model is often needed, however, to leverage a new technology (as in Apple's case); is generally required when the opportunity addresses an entirely new group of customers (as with the Nano); and is surely in order when an established company needs to fend off a successful disruptor (as the Nano's competitors may now need to do).

In March 1989 at CERN, Tim Berners-Lee submitted his proposal to develop a radical new way of linking and sharing information over the internet. The document was entitled "Information Management: A Proposal" (CERN Courier May 2009 p24). And so the web was born. Now, Berners-Lee, the World Wide Web Consortium (W3C) and the World Wide Web Foundation are launching a series of initiatives to mark the 25th anniversary of the original proposal, and to raise awareness of themes linked to the web, such as freedom, accessibility and privacy.

The World Wide Web, universally well known today, was preceded by an efficient software tool that was fondly named Gopher. The Internet Gopher, much like the Web, enabled users to obtain information quickly and easily. Why, then, did it disappear but the Web did not? Gopher faded into obscurity for two main reasons: hypertext and commerce.

The new world of mobile devices offers reasonable likelihood that virtual currency will prevail on a global scale. Currently, the bitcoin crypto-currency model appears to be a forerunner. Bitcoin, a highly disruptive technology, has both supporters and detractors. Nonetheless, in concert with other trends, some form of virtual currency, even if a successor to bitcoin, appears to have a path forward. Virtual currencies will likely gain in stature as other novel, unspecified, and disruptive innovations take hold in a world of increasingly autonomous systems. This department is part of a special issue on mobile commerce.
