Ronald Coase by rád Bitcoin? Jak Blockchain snižuje náklady na transakci a mění koasijskou firmu
Kaid, Amira ; Stroukal, Dominik (advisor) ; Prokop, Jaromír (referee)
The rising popularity of blockchain technology otherwise known as the technology that underlies the Bitcoin protocol has been the subject of a lot of investigation and enthusiasm among financial organizations for its potentially revolutionary properties that will likely change how the economy works in the future. The blockchain is a decentralized open source ledger that records bitcoin transactions and is maintained by a distributed network of miners. Blockchain technology however has many applications beyond currency and can be applied in various areas including the firm organizational structure and law. This thesis examines how blockchain technology would lower the transaction costs involved in organizing the firm and how it would thus change the role of the firm. Coase (1937) in his article (The Nature of the Firm) explained that firms exist and continue to operate in a hierarchal manner because of the transaction costs that are involved in using the market mechanism. This paper also examines how the blockchain would lower the transaction costs of resolving disputes through carrying out market transactions that were mentioned by Coase (1960) in (The Problem of Social Cost). In order to achieve this aim Coases framework is used to theoretically model a future firm and legal system which are blockchain-based and that use bitcoin in their transactions. The results indicate that blockchain technology would reduce the transaction costs pointed out by Coase in such a way that it would cause the firm to become less hierarchal in nature and would allow it to adopt a more inclusive and distributed management system. Similarly in the case of law the transaction costs would fall making it easier for parties to resolve their disputes using the market mechanism instead of having to rely on a central authority.

Automatizace nákupu
Cizner, Pavel ; Vinš, Marek (advisor) ; Jirsák, Petr (referee)
The research goal was to find out the current and possible level of procurement automation and its contribution to less routine and more creative jobs. The goal was accomplished by literature review and data collection via survey. The data collected evaluated enterprises in developing and developed countries. The research hypothesis of developing countries automating more than developed ones was not supported by the data tested via Mann-Whithey U test. The data collected was from 146 respondents from all around the world. Therefore, there are limitations of the conclusions. The thesis and its survey contributes to the knowledge about the level of procurement automation.

Bitcoin as the currency of the future?
Jaroš, Ondřej ; Vopátek, Jiří (advisor) ; Bína, Vladislav (referee)
This bachelor's thesis focuses on the digital currency called Bitcoin. The theoretical part discusses the concept of money (its history, issuance, the gold standard, etc.) as well as central banking and local currencies. It also tackles the concept of Bitcoin itself, the way it functions, its advantages and disadvantages and its issuance (so-called mining). The practical part discusses whether or not it is possible to profit through bitcoin mining, by speculating on its relative value to the (US) dollar and if it is possible for Bitcoin to replace traditional payment systems and currencies in the future (or at least prove itself to be a potent competitor).

Model ocenenia virtuálnej meny
Martiček, Matúš
Bachalor thesis defines main factors, that influence final value of digital currency Bitcoin. By means of comparing bitcoin with traditional currencies and other assets are defined differences, which exist among them. He points out the fact, that it is necessary to look at Bitcoin from different perspectives in order to value its price. Based on this fact, are created two models which value Bitcoin. First model is created on whole network's level and he reflects market price of Bitcoin. Second model is specified according to conditions of individual miner. By creating this model, it is possible to explain individual fundaments necessary for mining. By author is characterised and eventually included to these specific valuation models impact of demand on this currency, which has significant impact on its value.

Analysis and implementation of application for digital currency Bitcoin
DRDÁK, František
The thesis is focused on the topic of virtual cryptocurrency Bitcoin. The theoretical part is divided into several chapters. First of all, there is a chapter containing basic information about the currency's history, its development to the present, as well as principles of operation of this currency. Because it is a currency based on cryptographic principles next chapter summarizing cryptographic techniques, which is necessary to know for subsequent analysis of this currency. In other parts is elaborated a detailed analysis of the principles of Bitcoin. The main point of this analysis is a system of transactions, decentralized history, then joining the transactions into blocks and in the end creating blockchain. It also explains the principle of P2P networks. The practical part of this work focuses on the analysis and design of payment applications for mobile devices. There used open-source libraries such BitcoinJ. The application is developed in Java programming language with plugin for portable devices, which work under the operating system Android. For the purposes of analysis and design of graphical user interface is used UML diagrams. The specification of the UML diagrams was utilized by freely available graphics software and the result is also included in this work.
