Do consumers really trust cryptocurrencies?
The progress of change in society through digitization, globalization and the rapid de- velopment of technology prompts new and innovative opportunities for companies across the world. Over the past few years, nearly everything is based on smart devices that are able to communicate among themselves.
As a result, new technologies have arisen, been published and are able to be used by people around the world. One of the recently-released and most popular topics is blockchain. This term earned its attention through its innovative and unpresented form of technology and has motivated several parties to learn more about this issue, examine it more closely and develop it further.
Particularly the range of potential applicability makes it interesting for companies to analyse possibilities for implementation with respect to their own business.
In addition, blockchain is related to another term that has arisen along with this technol- ogy, namely cryptocurrency. Especially Bitcoin is the forefather in the world of digital currencies.
Over the past few years, Bitcoin has skyrocketed in popularity and value since its founding in There are many pros and cons and some powerful businessmen have published their own opinions based upon the respective commercial interests.
It is understandable that the CEO of one of the largest financial institutes clas- sify cryptocurrencies as a counterparty to the banking business. We create Bitcoins. What does it cost to create a U. Which one is the fraud? It's called proof of work. Taking a step back, the ubiquitous digitization can be stated as the baseline for compa- nies to research potential implementable innovations to digitalize their processes.
In this context, the term Industry 4. It implies a complex technical revolution that has led to an entire redesign of the industrial value chains. Ultimately, this involves a paradigm shift, namely the combination of virtual and real production chains in the form of a cyber physical system or the "Internet of Things".
Furthermore, the most suc- cessful digital firms across all industries are distinguished by the degree to which digital is integrated at all levels and functions of the enterprise. Digital informs everything from strategy and organizational structure to day-to-day operations and workplace cul- ture. Besides the already-mentioned blockchain technology, the central question in this study is based in the field of cryptocurrencies.
Essentially, currencies are the specific financial unit of a state, e. Dollar for the US or Yen for Japan.
Research methods can be distinguished into two main terms, namely quantitative and qualitative research. In addition, both methods imply research questions that ultimately have to be answered. Quantita- tive research is an explanation of phenomena that are analyzed by using numbers and statistically-based methods.
As a result, quantitative methods are empirical investiga- tions of phenomena that can be observed. Qualitative research tends to be concerned with words rather than numbers. In this thesis, a qualitative research approach is chosen, which allows a holistic view of the object of investigation and enables a general understanding of relevance and risks concerning blockchain and cryptocurrencies. Essentially, there are two major approaches to analyzing qualitative data.
On the one hand, there is the strategy of reducing large sets of data or the complexity in the data. The most common methodological step is to code the data. On the other hand, there is the most prominent way called content analysis. This strategy aims rather at expanding the material by producing one or more interpretations. In general, there are two fundamental approaches for the generation of scientific state- ments, namely deduction and induction.
Deductive theory is the most common view of the relation between theory and research. The researcher must skillfully deduce a hypothesis and translate it into operational terms.
Hence, there is a need to specify how data can be collected in relation to the con- cepts that make up the hypothesis. By contrast, an inductive approach includes state- ments regarding experiments or observations that are referred to general hypothesis and theories.
The findings are fed back into the stock of theory and the research findings are associated with a certain domain of enquiry. The methodological approach adopted in this study is the deductive approach. This the- sis aims to investigate a hypothesis with reference to qualitative research.
Moreover, the relevant literature is based upon secondary data, which has been initially produced by others for other research questions and not for the topic named in this thesis. The second part refers to corporate finance, whereby the fundamental char- acteristics and circumstances will be illuminated. Furthermore, Bitcoin will be investi- gated to declare the major differences and similarities in the context of corporate fi- nance. Subsequently, the core findings and results are valuated, whose explanation forms the baseline for answering the research question.
Finally, the outlook for future develop- ments in this technological area forms the conclusion of this study. In this chapter, the meaning of blockchain is explained based on technological charac- teristics and the current state of the art.
Possibilities of implementations for companies are emphasized and practical examples of successful applied processes based on this new technology show the advantage of future attention in this area. Additionally, the uniqueness of cryptocurrencies is explained and will be compared to usual currencies. Essentially, this section explains the technical concepts that make up blockchain and examples of business-relevant applications, as well as bridging the gap between a tech- nical and practical explanation.
The blockchain first emerged — largely unheralded — in Indeed, attention was di- rected towards the application based on the existence of which blockchain technology was made possible. The focal application and the first to run on this technology was the cryptocurrency Bitcoin.
Simply put, a blockchain is a ledger of transactions of digital assets: of who owns what, who transacts what, of what is transacted and when. Globally distributed nodes are linked by a peer-to-peer P2P communication network with its own layer of proto- col messages for node communication and peer discovery. They comprise individual computers called nodes that make their computational resources e.
In order to make the uniqueness of the technology of blockchain more tangible, it is necessary to understand the differences between centralized, decentralized and distrib- uted networks. In a centralized network Fig. Computers nodes need to be connected to the central computer to access these computing resources whenever they need it.
The control of the nodes is carried out centrally from the central computer. Therefore, it is guaranteed that every application runs on every single node in the same way. It is simply less time to breach a sin- gle node than it is to write exploit for more than one node.
In comparison to centralized computing systems, decentralized or distributed computing systems exploit a set of autonomous computers. Computers in the network have to co- ordinate the required tasks autonomously due to the absence of a central node. Conse- quently, every node in a decentralized computing system must be able to make its own decisions.
They can be based on their own information, interactions with or information from other nodes. The tasks are split up between nodes in a distributed network and all nodes are up-to-date with the current state of all other nodes. However, in decentralized computing, the resources are split up between nodes and each node queries for a resource and finds respective node on which needed resource exist. Based upon the connection of two or more partic pants, there is no central computer necessary to share the infor- mation between the participants.
Overall, centralized, decentralized and distributed networks are all networking frame- works that work effectively in various business or industrial sectors. The distributed structure of the blockchain network enables an independent exchange of information between nodes where one node does not depend on other nodes for information re- quired. All nodes only have to ensure that they are up to date by synchronizing with all other participants.
Resources and computing power are not shared but are independently distributed across all nodes. In order to explain the particularities of transactions, first and foremost the following facts can be seen as already derivate. First, the blockchain can be stated as a distributed P2P system made of the computational resources contributed by its users. Second, the P2P system uses the internet as a network for connecting the individual nodes. As already described in the previous section, blockchain is the ledger of transactions and forms the baseline of the authentication and verification technology for transac- tions.
Therefore, a distinction between users and nodes is necessary. This is possible as each of the nodes maintains a database of all historical, valid transactions that have been sent between the nodes of the network.
Blockchain uses cryptography as a base technology for uniquely identifying users with- in the blockchain and protecting their property. The idea is to treat the accounts of users like mailboxes. In the context of transactions, whenever a member of the network decides to send funds, they would follow a proce- dure similar to signing a check, except here the signing is done by using public and pri- vate keys.
A public key can be compared with an email address. In all these cases, the security concept is based on a separation of two kinds of information: first, publicly known information that serves as an address to a trapdoor-like box; and second, private information that serves as the key for opening the box and accessing the things it contains.
To sign the transaction, the private key is necessary. It can be compared with the password to an email account and the digital signature is similar to signing a check when the user is making a transfer.
Given that blockchain is a P2P system and it provides an open decentralized database of any transaction involving value, such as money, goods, property, work or even votes, it is not desirable for everyone to access the property assigned to the accounts managed by the blockchain.
Thus, the challenge is to protect the property assigned to the account without restricting the open architecture of the system. At this point, the term cryptog- raphy gains relevance. In order to enable a general understanding of the uniqueness of transactions processed within the distributed system, it is necessary to explain the different terms of cryptog- raphy from a more technical perspective. Essentially, cryptography has a long history of protecting secrets and messages that can be traced back thousands of years.
Modern cryptography has come a long way from its origins, although the principle is similar: it is about encrypting the original message by replacing letters and numbers so that the original message cannot be read unless the targeted person has the code or method to decrypt it. Simply put, the digital equivalent to close a lock is encryption, whereas the digital equivalent to open a lock is decryption.
In terms of blockchain, encrypted data is called cypher text. It is an extensive, incomprehensive pile of letters and figures to everyone who does not know how to decrypt this combination. In comparison to encrypted cy- pher text, decrypted cypher text contains the original data that has been encrypted. The symmetric approach can be practically explained as a safe with a strong lock, where the message is stored inside.

Research Proposal: Cryptocurrency User Attitudes Towards the Environmental Impact of Proof-of-Work
Muhammad Saad , University of Central Florida. Blockchains enable secure asset exchange in a distributed system, thereby facilitating innovative applications such as cryptocurrencies and smart contracts. Although the cryptographic constructs of blockchains are highly secure, however, their practical deployments are vulnerable to various attacks due to their application-specific policies, and their peer-to-peer P2P network intricacies. In this work, we take a top-down approach towards exploring those attacks, starting with the application-specific abuse of blockchain-based cryptocurrencies and concluding with the network conditions that violate the blockchain consistency. In the top-down approach, we first analyze the application-specific abuse of blockchain-based cryptocurrencies by uncovering 1 covert cryptocurrency mining in the web browsers, and 2 artificially inflating the transaction fee by attacking the blockchain memory pools. For both attacks, we show how the application policies are exploited to affect benign users.

Among experts, the vast energy demand associated with the rising popularity of cryptocurrencies and the potential impact on climate change have been discussed extensively. It is, however, unclear what attitudes the users of cryptocurrencies themselves have towards the consequences of its growing energy demand. Conducting the study will reveal whether cryptocurrency users themselves consider their energy needs to be problematic, and which stakeholders they hold accountable to reduce consumption.
