Virtual Wallet Compatible with Cryptocurrency
Marušin, Marek ; Rychlý, Marek (referee) ; Očenášek, Pavel (advisor)
The purpose of this thesis is to identify differences between classical payment systems and cryptocurrencies. A paper also compares the most well-known cryptocurrencies and explains how they work. By analyzing the principles of cryptocurrencies focused mainly on the Ethereum, we can see how virtual wallets for these digital tokens can be implemented and how we can work with custom tokens. A demonstration of created virtual wallet for Ethereum and custom ERC20 tokens is shown. Implemented practical example using Python programming language covers principles as generating private and public keys with appropriate addresses, manipulation with tokens and transactions or providing tests.

The Profitability of Standard Trading Strategies in Cryptocurrency Markets
Duda, Miroslav ; Krištoufek, Ladislav (advisor) ; Brož, Václav (referee)
The thesis attempts to determine how strategies used for forecasting and trad- ing on foreign exchange and stock markets perform when applied to cryptocur- rency markets. The approaches explored are ARIMA, VAR, MA Crossover, and Granger Causality using gold prices and S&P 500. The currencies traded are Bitcoin, Ethereum, Binance Coin, and Basic Attention Token. The models are trained on logarithmically transformed and differenced time series composed of the currencies' daily and hourly closing prices. Applying these strategies mostly leads to ambiguous results, with MA Crossover generally performing better than VAR, which in turn performs better than ARIMA. However, every strategy was moderately successful for at least one of the currencies examined. Trading on the hourly dataset was negatively influenced by sudden price jumps. ARIMA and VAR perform better in the inter-bubble periods. No significant Granger causality was found.

Examining the relationships among cryptocurrencies using Google Trends
Heller, Michael ; Krištoufek, Ladislav (advisor) ; Džmuráňová, Hana (referee)
The topic of our thesis is the examination of the relationships among cryptocur- rencies using Google Trends. In our thesis, we concentrated on four cryptocur- rencies, namely: Bitcoin, Litecoin, Ethereum Classic and Ethereum. We obtained the data of daily opening prices, daily trading volumes and daily Google Trends queries in order to examine the relationships among the four cryptocurrencies. Applying the Vector autoregression model and Vector error correction model, we constructed four models. The first model contains only four time series of daily prices of cryptocurrencies. The second model is the first model enriched by the respective four time series of Google Trends queries. The third model contains the four time series of daily trading volumes of the four cryptocurrencies. The fourth model is the third model enriched by the four time series of Google Trends queries of respective cryptocurrencies. Then we applied the Impulse response analysis and the Forecast error variance decomposition in order to find some relationships among the variables. We found that there is some correlation among prices, volumes and Google Trends queries containing the names of the four cryptocurrencies. According to our results acquired by the Forecast error variance decomposition, in all our models, Bitcoin has the...

Blockchain at the European Level
Drašković, Teodora ; Kunertová, Tereza (advisor) ; Vondráčková, Aneta (referee)
Blockchain at the European Level Abstract The objective of this master thesis is to provide a basic overview of the blockchain technology, its features and its potential utilization, including an overview of European legal regulations that might be applicable to the technology, under certain conditions. In the first chapter, the master's thesis sets forth the legal framework of the EU primary law that establishes or can establish the EU's competence to act in the matters of blockchain technology, depending on its legal qualification (especially in the context of the internal market - namely the free movement of services and capital). The second and third chapters provide essential description of features of blockchain and cryptocurrency and related services. A more detailed description is provided in Annexes I-IV of this thesis. Further, the legal status and applicable regulation of cryptocurrencies are assessed at the European and national levels and in terms of other global jurisdictions. The assessment also includes the recent CJEU's judgment in the case Hedqvist, according to which bidirectional exchange services (purchase of cryptocurrency for fiat currency and vice versa) are to be exempted from VAT obligation under the VAT directive. In line with the CJEU's reasoning and the Advocate General's...

Cryptocurrencies are becoming popular and the demand for monitoring transactions inside them increases alongside with it. In this thesis, I describe few of the most widespread cryptocurrencies built on top of a blockchain and how to obtain information of their transactions in order to raise alarms. I discuss existing solutions and describe application Cryptoalarm designed for monitoring transactions involving specific addresses in order to raise alarms. Cryptoalarm scans blockchains of cryptocurrencies such as Bitcoin, Bitcoin Cash, Litecoin, Zcash, Dash, Ethereum and raises alarms about address activities in real-time.

Changes of financial system in the context of financial crisis
Karan, Boris ; Šíma, Ondřej (advisor) ; Pour, Jiří (referee)
In this paper, we analyse the relation between financial system and financial crises. Our goal is to find how, on the one hand, changes in the financial system affect the prospects for financial crises and, on the other hand, how the occurrence of financial crises shape the core elements of the financial system. We start by defining the financial crisis from three different perspectives. After it, we present the comprehensive history of financial crises that will allow us to continue by drawing some common patterns that are universal. Universal patterns in crises give us the ground for contemplating on some universal policy responses where we again follow different approaches. Taking into account the specifics of modern times and using the young and promising economy based on the blockchain, we are asking the question is this time different?. Analysis of initial development steps in the digital, trustless world gives us the basis for drawing parallels with the reality and the history. Our results suggest that there are many similarities throughout history and between the real and digital world. Instead of providing an exact answer on the question is this time different we conclude that there is a present strong feeling of Deja vu.
