Today, there exist several thousands of cryptocurrencies and the market value of all these coins has recently broken the two-trillion-dollar mark. Central banks are addressing the issue, the general public is discussing its pros and cons, and current price fluctuations have become part of mainstream news. All of this serves as undeniable evidence that cryptocurrencies have become much more significant than their creators had likely ever imagined some 15 years ago. But how did this technological innovation actually come about — who were the people behind this project, what was their motivation, and how did all of this unfold? Part one dealt with the early days of cryptocurrencies through to the emergence of Bitcoin.

Bitcoin as an Innovative Payment Currency in Germany: Development of the e-Gold Standard

Designed by an anonymous creator, Bitcoin is an intriguing to modern technology and payment transaction infrastructure that has the potential to become a game changer within the sector of virtual payments.

But as with any new technology, there are many obstacles and threats on the path towards mainstream acceptance. In this thesis we analyze key shortcomings of the Bitcoin protocol and Bitcoin as a currency. Moreover, we explore competitors that may one day be able surpass Bitcoin and even make it obsolete. The key question we as is if a suitable competitor can replace Bitcoin or can the open source virtual currency be improved itself in other to make competition obsolete.

My gratefulness goes first and foremost to the people who supported me during the research and writing phases of this diploma thesis. Getting a closer look at the technological innovation that Bitcoin represents and the potential benefits that it could offer was a very valuable experience that guided me through the process of creating this thesis.

Furthermore, I want to thank Univ. Likewise, I want to thank Univ. Next, I want to acknowledge the outstanding work that MMag. Matthias Korp has provided with his diploma thesis about Bitcoin in , which represented the basis for my thesis. Additional thanks and appreciation go to family and friends who kept me motivated and provided me with valuable input during this phase of my life. This thesis aims to look at the virtual currency Bitcoin in order to investigate some of the potential of cryptocurrencies.

Traditional classifications for currencies do not adequately apply to Bitcoin. Regulators and banks currently share this view on cryptocurrencies. Existing currencies have certain common characteristics that Bitcoin does not share. It is a new type of financial technology that entered the global market in and has since been able to draw the attention of investors, business leaders, regulators and politicians.

Whereas a Dollar, Yen, Yuan or Euro can be hold like a currency, they cannot be secured and transacted simply by itself. Individuals have to rely on third party intermediaries in order to transfer funds for them and in order to store them securely. Contrary to that, one cannot focus on Bitcoin as a currency without acknowledging that it is also a transaction system in itself and would not be able to function is one part of this duality is gone. In fact it is even more precise to look at Bitcoin as a decentralized transaction and financial services system, with a currency function being only one aspect of the technology.

In this thesis, we evaluate not only the technological characteristics of decentralized, cryptographic currencies, but also the current applications that are in development and which can result into a number of decentralized financial services that are not subject to financial institutions.

Third party intermediaries, such as banks and payment providers and other non-bank entities all essentially rely on trust. They provide security, confidentiality, fraud protection, transaction infrastructure, payment disputes and reversals, access to financial products and services, international money transfers and the like. In order to be able to provide these services, they have to charge fees and interest from customers.

In many cases, these customers must meet a set of criteria in order to have access to banking services. Moreover, they have to provide institutions with a significant amount of personal information, private information and confidential data about them and their financial characteristics.

Thus customers have to enter a costly, trust-based relationship with institutions in order to engage into financial activities and benefit from financial services. So what are the prospects of a technology that was invented and designed in order to provide most of these services at a low-cost, trust-less basis? Do financial intermediaries have reasons to ignore this technology and expect that cryptocurrencies will remain only present within niche markets for nerdy or technologically savvy people, or should they make use of the open-source code and incorporate some of its features into their systems?

This thesis attempts to provide some answers to these questions and give an outlook for what can potentially be expected by cryptocurrencies. We discuss how cryptography is employed by the system as well as how it facilitates secure transactions.

We explain the significance of the solution to the Byzantine Generals problem that the cryptocurrency represents and that of decentralized networks. Chapter four goes into detail about current and persistent shortcomings that can be identified. We discuss issues concerning network delay, incentive schemes of the decentralized network, transaction confirmation delays, energy consumption and the like. In chapter five we discuss a number of alternative cryptocurrencies that emerged after Bitcoin was developed and discuss some of their features that address certain weaknesses of Bitcoin that we discussed in chapter four.

Moreover, the question whether there is a Bitcoin 2. Chapter six details a special type of cryptocurrency that is already in use within a few banks. Ripple is a network, a distributed exchange and a cryptocurrency that is very akin to Bitcoin, but differs in some key aspects. It provides a different solution to the Byzantine Generals problem and is specifically targeted towards being used as a transaction system for banks and financial institutions. Chapter seven gives an outlook on a proposal made by key people within the cryptography scene that is currently in development.

Bitcoin side chains are alternative block chains that give Bitcoin additional features. These could incorporate features of alternative cryptocurrencies without altering the Bitcoin protocol itself. We discuss the influence that side chains could have on the cryptographic currency market.

Bitcoin is a peer-to-peer version of electronic currency that allows direct payments between two parties without a financial intermediary. It is based on a decentralized network that facilitates and verifies transactions.

It allows users to verify valid transactions and generate bitcoins by solving complex mathematical puzzles, which are based on a proof-of-work PoW concept. Bitcoin is both a special type of virtual currency and a peer-to-peer transaction system. It is based on a network of nodes that all share data and hardware resources in order to form a chain of transactions that are stored on the so-called block chain.

Nakamoto described Bitcoin as a purely peer-to-peer version of electronic cash which allows sending transactions from one person to another without relying on a third party payment transmitter.

The first bitcoins were created on January 3rd by solving the so-called genesis block, which was accomplished by Satoshi Nakamoto.

What makes Bitcoin a significant innovation are two main reasons. First, it is the first successful attempt to establishing a cryptocurrency which has managed to gather a significant following behind it. Secondly, Bitcoin offers important technological innovations to the field of financial transactions that were previously inexistent.

It solves the so-called Byzantine Generals problem in a way that enables the creation of a payment transaction system that does not rely on trust and therefore does not require a number of services that traditional financial intermediaries provide, as the software itself is designed to provide these functions.

It is a decentralized, global means of payment that does not require financial intermediaries in order to conduct them. Bitcoin transactions are significantly less expensive than currently existing payment transaction services. These forms of transactions rely on financial intermediaries and provide services to customers, such as security, facilitation, verification. Many of these services are, however, necessary to provide the current electronic payment infrastructure.

Financial intermediaries are also present within the Bitcoin ecosystem. Examples such as Coinbase or Bitpay provide wallets services to securely store bitcoins or facilitate instant fiat conversion of received bitcoin transactions in order to hedge against price volatility. With these intermediaries present, transaction fees are still considerably lower than those of almost all current transaction services providers, which would broadly require 0.

Bitcoin must be seen as both a type of virtual currency and a decentralized transaction system. A clear differentiation from either use is not a simple task. Central banks of several countries have already stated that Bitcoin cannot be defined as a currency but rather resembles a commodity. Contrary to what is often believed, bitcoins are not simply ordinary computer files that are stored on a hard drive and can thus be treated like any other data.

Bitcoins exist in a shared, globally networked database, which is stored simultaneously on a great many of servers across the world. All of these network nodes maintain identical copies of the same database.

Bitcoins therefore exist in many locations simultaneously and can by itself be moved between locations or exchanged between peers.

Ownership of bitcoins is represented by possessing the knowledge about a cryptographic key that allows access to bitcoin funds and enables transactions of bitcoins between Bitcoin addresses. Cryptographic keys are strings of alphanumeric characters that allow users to edit the shared database, e.

Nakamoto described how Bitcoin relies on a peer-to-peer decentralized network that enables verifying transactions with a proof-of-work PoW method. PoW is used as a verifier to ensure that a enough computational effort has been performed in order to enable secure payments.

A simple peer-to-peer financial payment network would still be vulnerable to malicious attacks and theft. In fact, it would be very easy to do so within decentralized networks. The key innovation about Bitcoin that it provides security to the network and also provides similar benefits that financial intermediaries offer to financial networks.

Transactions are verified based on a proof-ofwork PoW concept that distributes financial funds and prevents manipulation of the financial network. PoW imposes costs and resource requirements that prevent malicious attacks due to making them very resource-intensive and therefore unprofitable.

Bitcoin is based on a SHA algorithm and designed to create new blocks every 10 minutes for which miners are competing against each other in order to solve a block and broadcast it to the remaining network first. Bitcoin and many other virtual currencies are, however, also subject to features that are less desirable and could cause them to fall under intense scrutiny by regulators, politics and law enforcement.

Virtual currencies can also be misused to facilitate tax avoidance, money laundering, illegal goods purchases, fraud, and terrorism finance. Gup also noted that Bitcoin could be used as a secure store of value. This, however, is currently very questionable, as virtual currencies are still unregulated, highly speculative assets that are subject to limited liquidity, intense volatility and considerable operational risk theft, business failure, hacking, etc.

Money can be distinguished into informational and non-informational depending on e. They acknowledged that Bitcoin could also be a hybrid class of informational money that exhibits aspects of both technically informational money TIM and exclusively informational money EXIM.

When attempting to analyze Bitcoin, it is fundamentally important to understand that the underlying technology. Digital currencies have been proposed and developed long before the invention of Bitcoin.

Tanaka described the different aspects of digital cash just two years after the first online shops were opened and internet banking was still in its infancy.

Cost Reduction: transferring funds through the internet is significantly less expensive when compared to the traditional banking system, as online payments do not, or only to a very limited extend, require physical presences, human resources and electronic transaction systems.

Moreover, digital cash payments can be done through already existing internet infrastructure, such as personal computers and already active online presences. Cross-country money transfers: In the absence of national borders in the Internet, money can be transferred across countries without international money transfer infrastructure. Digital cash eliminates transfer fees as well as currency exchange fees.

Moreover, in certain aspects of cross-country money transfers, digital cash would eliminate currency exchange risks. Accessibility: Digital cash systems could be accessed and used by anyone who is connected to the internet, whereas conventional banking and non-bank financial service providers limit accessibility of their services. Limits as to who can use credit card payments or from which region in the world the payment can originate are not present with digital currency payments.

Due to these reasons digital cash certainly offers the potential for more efficient and broader financial services that are not present within the walled-garden architecture of the global financial market. Tanaka , however, also points out obvious drawbacks for digital cash.

Internet currencies, due to its anonymity and the potential for untraceable money transfers could facilitate tax evasion and money laundering. Moreover, due to the absence of a central bank or institution backing the value of digital cash the exchange rate of digital currencies would be inherently unstable and there is a potential for financial crises as operations on the internet are subject to the thread of power outages, theft and malicious software.

Why nobody can withdraw bitcoins from one of the currency’s largest exchanges

Cryptocurrencies are distributed systems that allow exchanges of native and non- tokens between participants. The availability of the complete historical bookkeeping opens up an unprecedented possibility: that of understanding the evolution of a cryptocurrency's network structure while gaining useful insights into the relationships between users' behavior and cryptocurrency pricing in exchange markets. In this article we review some recent results concerning the structural properties of the Bitcoin Transaction Networks , a generic name referring to a set of three different constructs: the Bitcoin Address Network , the Bitcoin User Network , and the Bitcoin Lightning Network. The picture that emerges is of a system growing over time, which becomes increasingly sparse and whose mesoscopic structural organization is characterized by the presence of an increasingly significant core-periphery structure. Such a peculiar topology is accompanied by a highly uneven distribution of bitcoins, a result suggesting that Bitcoin is becoming an increasingly centralized system at different levels.

Financial media eagerly covers each new dramatic high and stomach churning decline, making Bitcoin an inescapable part of the landscape. While the wild volatility might produce great headlines, it hardly makes Bitcoin the best choice for novice investors or people looking for a stable store of value. Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Since its public launch in , Bitcoin has risen dramatically in value. Because its supply is limited to 21 million coins, many expect its price to only keep rising as time goes on, especially as more large, institutional investors begin treating it as a sort of digital gold to hedge against market volatility and inflation. We've combed through the leading exchange offerings, and reams of data, to determine the best crypto exchanges.

Now, tens of thousands of Quadriga CX users are wondering if they will ever see their funds again. Its meltdown shook investors in the volatile emerging marketplace - but the calamity at the Tokyo-based company proved a boon for a new Canadian online cryptocurrency exchange. Some five years later, Cotten's sudden, untimely death has left thousands of his customers scrambling for information about their own missing funds. This month, Quadriga - which had grown to become Canada's largest cryptocurrency exchange - was granted temporary bankruptcy protection in a Canadian court. The firm said it had spent the weeks since Cotten's death trying desperately to "locate and secure our very significant cryptocurrency reserves".
