▼ A tecnologia Bitcoin, desenvolvida no final da década passada, em plena crise financeira, pretendeu ser, desde a origem, uma alternativa ao sistema financeiro vigente. Para Nakamoto, o criador do Bitcoin, o principal problema deste sistema reside no facto de ser necessária a presença de intermediários de confiança (v.g., instituições financeiras), para que as pessoas possam realizar transações financeiras. Esta configuração trilateral, paradigmática das transacções financeiras, leva a um aumento dos custos de transacção (desde logo, pela presença de uma terceira parte) mas também à necessidade de partilhar informação sobre as partes envolvidas (o que faz perigar a privacidade das pessoas). Nakamoto apresenta, então, em 2008, um sistema de pagamentos online alternativo, baseado em código criptográfico e informático, mediante o qual seria possível (no seu entendimento) substituir os intermediários de confiança por uma confiança no código matemático. Por outro lado, e posto que as transações realizadas neste sistema alternativo são denominadas numa unidade própria, o Bitcoin, o sistema assume uma natureza dual: é simultaneamente um sistema de pagamentos, de troca, e uma moeda digital. Com a presente dissertação pretendemos, por um lado, fazer uma revisão da literatura existente sobre o Bitcoin, e com isso perceber o estado da arte. Por outro lado, pretendemos também confrontar os objectivos que orientaram Nakamoto, no desenho do protocolo, com as evidências sobre o seu funcionamento. Resumidamente, Nakamoto pretendeu desenvolver um sistema que fosse descentralizado, e acessível a qualquer pessoa: disso fez depender, inclusivamente, a segurança do próprio sistema. Não obstante, a arquitectura do sistema, a sua complexidade para o homem médio e as dinâmicas próprias do capitalismo parecem estimular a centralização. Com base na revisão de bibliografia realizada concluímos que existem vários níveis de centralização no sistema. Ademais, ao escrever o protocolo do Bitcoin, Nakamoto introduziu um limite de emissão monetária, que será atingido em 2140, num total de 21 milhões de Bitcoins. Esta natureza deflacionária, da própria moeda, leva muitas pessoas a comprar Bitcoins como um investimento financeiro, aguardando a sua futura valorização. Ou seja, da já reduzida oferta monetária, uma grande parte não é utilizada para realizar transacções, resultando num mercado pouco líquido, e numa hipervalorização do Bitcoin (por confronto com outras moedas).

Denna uppsats undersöker nyttan som uppfylls i bytesmedlet Bitcoin i förhållande till densvenska kronan i allmänhet och de makroekonomiska konsekvenserna av sådannyttouppfyllelse i synnerhet. Undersökningen utgår från att nyttan som kan härledas urpengar kommer av dess inneboende kvalitéer, främst i form av dess möjligheter att bevaravärde i samt dess möjligheter att generera låga transaktionskostnader. Undersökningenfinner att det finns möjligheter för Bitcoin att generera högre nytta än den svenska kronanunder vissa omständigheter. Detta främst i avseendet värdelagring till följd av denregelföljda penningmängdsutveckling som Bitcoin karaktäriseras av och i tider där densvenska kronans monetära bas expanderas när penningpolitik förs och inflation uppstårsom följd. I sådana tider finner undersökningen att Bitcoins ökade nytta i jämförelse medden svenska kronan skapar incitament för individer att byta valuta från den svenskakronan till Bitcoin om vinsterna i nytta är stor nog. I detta uppkommer den centralaanalysen om huruvida Bitcoin och dess användning introducerar systemrisker i denmakroekonomiska politiken. Om det finns en god och lättillgänglig möjlighet att bytavaluta när penningpolitik skapar inflation i den svenska kronan kan också risk finnas attpenningpolitiken misslyckas. Detta till följd av det köpkraftsbortfall som sker i densvenska kronan när dess efterfrågan minskar om människor byter valuta. Undersökningenfinner att resultatet beror på vilket teoretiskt perspektiv som anläggs i analysen och att detfaktiskt råder tydliga systemrisker av Bitcoin i ett keynesianskt perspektiv, medanmotsatsen, att systemriskerna finns inneboende i den svenska kronan och att Bitcoin kanvara en väg från dessa systemrisker, är slutsatsen av en analys utgående från denösterrikiska konjunkturcykelteorin. Trots de uppfattade systemriskerna med enkeynesiansk syn, föreslås reformer för att Bitcoin ska kunna samexistera medkeynesianska penninginstitut för att kunna ta vara på den nytta som kan resultera avBitcoins användning som bytesmedel.

This paper investigates the fulfillment of utility in the currency Bitcoin in relation to the Swedish krona in general andthe macroeconomic consequences of such fulfillment of utility in particular. The paper starts with the assumption thatthe utility generated by money is deduced from its qualities, mainly the quality in storage of value and the currency´spossibilities of generating low transaction costs. The investigation finds that there are possibilities that Bitcoin maygenerate a higher utility for its users than the Swedish krona under some circumstances. This mainly from Bitcoinsqualities in storage of value due to its predetermined change in money supply and in times when the Swedish krona´smonetary base is expanded by monetary policy and its subsequent inflation. In such periods when monetary expansionis undergoing in the Swedish krona, the investigation finds that the expected higher utility in Bitcoin in relation to theSwedish krona may cause a change of individuals…

Opinnäytetyön tarkoituksena on tutkia lohkoketjuteknologiaa ja selvittää kuinka sitä voidaan soveltaa tiedostojen tallentamiseen ja aikaleimaamiseen käyttäen Factom lohkoketjua. Samalla käydään läpi lohkoketjuteknologian mahdollistavia tekijöitä. Lohkoketju on yksinkertaisesti selitettynä hajautettu, muuttamaton tietokanta. Nämä ominaisuudet saavutetaan käyttäen P2P verkkomallia, kryptografiaa ja peliteoriaa. P2P verkko pitää huolen lohkoketjun hajautuneisuudesta ja kryptografia takaa lohkoketjun rakenteen. Uusien lohkojen luomisesta ja sääntöjen noudattamisesta vastaa konsensus algoritmi, johon on sovellettu peliteoriaa. Lohkoketju muuttamattoman luonteensa takia soveltuu hyvin virtuaalisten valuuttojen luontiin. Jokainen valuutansiirtotapahtuma voidaan jäljittää valuutan luomishetkestä nykypäivään, mikä takaa sen, että saman valuuttayksikön käyttäminen kahteen kertaan on vaikeaa. Virtuaalisten valuuttojen lisäksi lohkoketju soveltuu hyvin tärkeiden dokumenttien varmentamiseen. Jokainen lohko sisältää luomishetken aikaleiman, joten lohkoon tallennettu data on sidottu tähän ajanhetkeen. Tämä tekee dokumenttien auditoinneista helppoa, sillä lohkoketjussa on todiste dokumentin olemassaolosta tietyssä muodossa tiettynä ajankohtana. Factom lohkoketju tarjoaa helpon ja halvan tavan aikaleimata tiedostoja luotettavasti. Hinta yhden kilotavun tallentamiseen on 0.001 dollaria. Yhteen kilotavuun mahtuu täydellisesti dokumentista hajautusalgoritmilla tuotettu tiiviste, joka toimii dokumentin sormenjälkenä. Factom lohkoketju myös ankkuroi tallennetun datan Bitcoin lohkoketjuun, varmistaen sen muuttamattomuuden. Lohkoketjuteknologia on vielä nuori ja nopeasti kehittyvä ala. Suurin osa lohkoketjuista ja niiden päälle rakennetuista palveluista on vielä kesken. Siitä huolimatta teknologian potentiaali arvon varastointiin ja datan varmentamiseen on kiistämätön.

The goal of this thesis is to explore the possibilities of blockchain technology and explain how it can be used to store and timestamp data using Factom blockchain. It also explains the key principles that enables the blockchain technology. Blockchain is simply explained decentralized and immutable database. These qualities are achieved by using P2P networking, cryptography and game theory. P2P network makes sure that blockchain is decentralized and cryptography secures the structure. Consensus algorithm makes sure that every participant plays by same rules and ensures the decentralization of block creation process. This is achieved with smart usage of game theory. Because of its immutable nature, blockchain makes it possible to create virtual currencies. Every transaction can be validated from the very beginning which makes blockchain based currencies scarce, open and hard to double spend. In addition to virtual currencies, blockchain makes it possible to store and timestamp data. Every block contains the timestamp of when it was created. Data inside the block gets automatically timestamped because of this. This makes document auditing process…

▼ The aim of this study was to illustrate an unexplored illegal exploitation of legal businesses, with the purpose of limiting this market and especially the related transactions. The issue of transactions regarding illegal material executed with credit cards was solved through involving the companies who issues the credit cards, making the market more transparent and thus preventing this kind of transactions. The thesis will illustrate how cryptocurrencies, such as Bitcoin, are being exploited regarding illegal transactions and more specifically, transactions regarding selling and purchasing Child Abusive Material within file hosting services (cyberlockers). The analyzed data was gathered using a webcrawler and different methods for analyzing correlation were implemented on the data to find relationships between different data points. The data points were then clustered, using an algorithm to create a relationship network. The developed model analyzed the data to identify trends and patterns regarding the illegal transactions and the results can be used to find the most prominent users who are potential perpetrators that actively distributes illegal material. A deeper analysis is then performed on the, according to the model, most interesting users in an attempt to identify their underlying identity. When cryptocurrencies are used by perpetrators to pay and get paid for illegal material, the transaction flows cannot immediately be connected to specific identities and therefore it is required to first identify potential perpetrators and track their transactions, to later compare them with the transactions that has already been identified as payments for illegal material. Apart from this model, a framework has been created to identify certain patterns and trends regarding the cyberlockers’ transaction flows. This was performed through analysis of the transaction flows connected to cyberlockers that were suspected to contain Child Abusive Material or other illegal material. With the results from the first and second model, the most interesting cyberlockers for future investigations were discovered, according to the trends and patterns in their surrounding transaction flows. When that analysis was performed and the first model was implemented, potential perpetrators was identified through collaborations between the investigating unit, the Police, the cyberlockers in question and the relevant exchange services. Through this collaboration the identities of the perpetrators are revealed and the transaction flows can then be analyzed to limit further distribution of Child Abusive Material within cyberlockers and consequently limit the illegal transactions with cryptocurrencies. Keywords: Bitcoin, Child Abusive Material, Cyberlockers, Illegal payments, Cryptocurrency, Webcrawler, Correlation, Relationship network.

▼ Payment channels secured with cryptocurrency as collateral enable users to make many transactions with few blockchain broadcasts. Networks of payment channels have emerged as a proposed solution to Bitcoin’s scaling problem. Since the proposal of the first payment channel network, the Lightning Network, alternatives promising significant improvements, such as the Sprites protocol, have been proposed. Without at-scale implementations to analyze in situ, it is difficult to make meaningful comparisons of payment channel network protocols. In order to bridge this gap, we introduce a new simulation framework that can be used to evaluate how different payment channel network protocols will perform in both the expected and worst cases. Our framework is generic and accommodates benchmarking across different variants of payment channel network protocols, network topologies, routing algorithms, and user behaviors. User spending behavior in our payment channel network simulator is generated based on behavioral modeling techniques used in credit card fraud research. Our simulation is the first payment channel network simulator to seed user behaviors with data from real-world credit card users. Our framework can be used to evaluate expected case performance and resiliency to attacks across different payment channel network protocols and routing algorithms. We demonstrate the utility of our framework through comparisons of the Lightning Network to Sprites. We also compare the proposed decentralized routing algorithm, Flare, to an ideal centralized routing algorithm. Our results reveal that if spending behaviors are similar to those of credit card users, scale-free network topologies achieve higher throughput and resiliency compared to small-world networks. We also confirm that the Sprites protocol enjoys numerous advantages over the Lightning Network including smaller durations, shorter path length payments, and greater resiliency, all of which are most significant in decentralized topologies using decentralized routing algorithms.

▼ A tecnologia Bitcoin, desenvolvida no final da década passada, em plena crise financeira, pretendeu ser, desde a origem, uma alternativa ao sistema financeiro vigente. Para Nakamoto, o criador do Bitcoin, o principal problema deste sistema reside no facto de ser necessária a presença de intermediários de confiança (v.g., instituições financeiras), para que as pessoas possam realizar transações financeiras. Esta configuração trilateral, paradigmática das transacções financeiras, leva a um aumento dos custos de transacção (desde logo, pela presença de uma terceira parte) mas também à necessidade de partilhar informação sobre as partes envolvidas (o que faz perigar a privacidade das pessoas). Nakamoto apresenta, então, em 2008, um sistema de pagamentos online alternativo, baseado em código criptográfico e informático, mediante o qual seria possível (no seu entendimento) substituir os intermediários de confiança por uma confiança no código matemático. Por outro lado, e posto que as transações realizadas neste sistema alternativo são denominadas numa unidade própria, o Bitcoin, o sistema assume uma natureza dual: é simultaneamente um sistema de pagamentos, de troca, e uma moeda digital. Com a presente dissertação pretendemos, por um lado, fazer uma revisão da literatura existente sobre o Bitcoin, e com isso perceber o estado da arte. Por outro lado, pretendemos também confrontar os objectivos que orientaram Nakamoto, no desenho do protocolo, com as evidências sobre o seu funcionamento. Resumidamente, Nakamoto pretendeu desenvolver um sistema que fosse descentralizado, e acessível a qualquer pessoa: disso fez depender, inclusivamente, a segurança do próprio sistema. Não obstante, a arquitectura do sistema, a sua complexidade para o homem médio e as dinâmicas próprias do capitalismo parecem estimular a centralização. Com base na revisão de bibliografia realizada concluímos que existem vários níveis de centralização no sistema. Ademais, ao escrever o protocolo do Bitcoin, Nakamoto introduziu um limite de emissão monetária, que será atingido em 2140, num total de 21 milhões de Bitcoins. Esta natureza deflacionária, da própria moeda, leva muitas pessoas a comprar Bitcoins como um investimento financeiro, aguardando a sua futura valorização. Ou seja, da já reduzida oferta monetária, uma grande parte não é utilizada para realizar transacções, resultando num mercado pouco líquido, e numa hipervalorização do Bitcoin (por confronto com outras moedas).

▼ Every time we place a bet, we implicitly trust the other participant to pay in the case we win. For this reason if we deal with people we do not know or trust, we do not bet directly with them, and instead we use a casino or other gambling sites. We expect the law or even casino reputation to help us to enforce good behavior. Cryptocurrencies made possible to store and transfer value easily without using centralized control. Given its recent popularity, many decentralized applications have been proposed and implemented on top of them. Among them, gambling. It is currently possible to safely bet with a stranger on random events using cryptocurrencies. We can bet on the value of digital dice, cards or roulette. Neither trust nor centralized entities are required. In this work we propose a protocol on top of Bitcoin to place bets on real world events in a decentralized and trustless fashion. Our protocol uses a set of oracles to bring the outcome of the event on which the bet depends into the blockchain. When a certain threshold of the oracles have reported the same outcome for the event, we unlock the winner s prize. The protocol was designed to automatically move the money to one of the players in that case, so oracles do not take control of the prize, they only decide between two possible outcomes. Economic incentives are placed to encourage good behavior on the participants. Oracles get paid if and only if they provide the right answer, where right is defined as the answer provided by the majority of them. Also, oracles are required to place a deposit to participate. This allows the protocol to establish economic penalties if the oracle fails to answer. Once the bet is placed, the prize is locked waiting for the oracles answer. Players relinquish their control over the money until the oracles decide the winner or a previously defined ti- meout expires. In case of timeout, each player gets half of the prize. Using Bitcoin scripting language, the protocol guarantees fairness and execution correctness with both, a dishonest minority of oracles as well as a dishonest peer, at least once the bet is placed. Before that a dishonest peer can cause limited economic damage to an honest player. Yet the attack produces no net gain: it costs the attacker as much as the amount of the damage done to the victim. Dishonest oracles, before the bet is placed, can cause small economic damage to both players equally, although the cost for this attack is a parameter set by the players. The protocol was implemented and run in the Bitcoin testnet using the official client to ve- rify the transactions. Our implementation is currently available as an Open Source project. Discussion on the trade off between the protocol cost and economic incentives for the par- ticipants are included in this work. We also provide a detailed cost analysis of running the protocol. We believe this work s contribution is a novel way of reasoning and deciding about real world events while integrating the outcome into the blockchain. The protocol can be… Advisors/Committee Members: Hevia Angulo, Alejandro (advisor).

▼ The ability to predict financial markets has tremendous potential to limit exposure to risk and provide better assurances of annualized gains. In this thesis, a model for predicting the future daily price of Bitcoin is proposed and evaluated in comparison to that of a purely random model. Bitcoin is a novel digital currency that relies on cryptography instead of a central authority to verify transactions. Without a central authority, Bitcoin requires a complete list of all transactions to be made public so that they can be verified by all users. This unique feature of Bitcoin, where all transactions are public, is exploited by the model to predict the future price directions based on the actions of Bitcoin users. The daily activity of the markets, aggregate network features, and the actions of major network influencers are all used as features for the predictive model. Where major network influencers are defined as users that accumulate a disproportionate amount of wealth within the Bitcoin network compared to others. The information about the actions of all Bitcoin users are extracted from the blockchain and stored in a relational database for ease of use. Two metrics were created to identify the major network influencers based on the history of their actions recorded on the blockchain. The first metric, based on the concept of an h-index, often used in academia to rank authors by their citations, is used to rank users by the amount of wealth they accumulate monthly. The second metric is based on the optimization of multiple objectives, the maximum increase in wealth with the least amount of activity using Pareto optimization. All of the major network influencers identified were then used as features, in combination with aggregate network features, and market data, to test and evaluate several predictive models. The models created were based on non-linear equations, support vector machines, decision trees, and XGBoost; all evaluated and compared using the same data. The XGBoost model consistently proved to be much more accurate than all other models and was used for the final set of experiments. The XGBoost model was compared to that of a purely random Monte Carlo model using the entire history of data for the period of 2013???2016. The first set of experiments were conducted using various sizes of training and testing data, in each case the XGBoost model had an accuracy 20% greater than that of the Monte Carlo model. For the final experiments, the model was tested in a realistic scenario, predicting the price direction for each future day, while also being re-trained using the results of each new day. The XGBoost model achieved a much better performance in comparison to the Monte Carlo model, which had approximately 50% accuracy, whereas the XGBoost model had 70%???79% accuracy.

▼ Created in 2008 and rising to prominence in 2017, Bitcoin continues to generate controversy as to whether it is a speculative asset or the harbinger of a future of global, decentralized commerce. The focus of this paper is to investigate the properties of Bitcoin and its market by assessing asset specific factors (users, hash rate, etc.) and traditional market factors (market risk, currency risk, etc.). The objective is to quantify the impacts of these forces as drivers of Bitcoin returns and to develop a risk measurement framework with the potential to inform future use cases. The analysis is broken out into two parts. The first seeks to quantify the impact of asset specific "supply and demand" factors with respect to Bitcoin's daily price return and volatility and to determine the relative efficiency of the nascent Bitcoin market. To do this a GARCH model is specified which enables the measurement of return impacts and volatility within a single model. A back test and forecast are then conducted to determine if the conditional value at risk and expected shortfall can be accurately captured by the model. We determine the Bitcoin market is weakly efficient, returns are highly impacted by supply and demand factors and that the specified value at risk model accurately describes the exceptional volatility. The second part incorporates a set of macro-financial variables into the model to determine Bitcoin's exposure to traditional sources of risk; such as stock and currency market returns. The results show that Bitcoin is largely unimpacted by broad macro-financial variables once supply and demand variables are properly accounted for. This suggests that although Bitcoin is a weakly efficient market it is generally disconnected from worldwide capital and currencies market. This further suggests that Bitcoin may have currently limited "real world" use cases which is an important consideration for investors.

Notre recherche part du constat empirique de l’omniprésence et de l’extension permanente des techniques numériques dans des domaines variés de la vie sociale contemporaine, et ce alors que ces techniques ne se déploient tous azimuts que depuis le tournant des années 1960. Jusqu’à cette date, leur conception et leur mise au point étaient menées en vue d’améliorer la productivité de tâches calculatoires bien spécifiques, dans les domaines scientifique, militaire et statistique. Ce constat d’un déferlement numérique nous amène à nous interroger sur les ressorts de sa dynamique, notamment en lien avec ceux de la production marchande qui constitue le contexte particulier de son avènement. Notre démarche consiste à concevoir un modèle socio-technique de l’informatique qui puisse rendre compte de ces spécificités et qui s’appuie sur une analyse formelle des propriétés de la machine au coeur de l’informatique, à savoir l’ordinateur, que nous caractérisons par la forme bifide abstrait/concret de son fonctionnement. Après avoir fixé le cadre théorique dans lequel peut être saisi la rencontre entre numérique et capital, il s’agira pour nous de proposer une mise à l’épreuve de ce cadre sur des objets qui animent aujourd’hui les débats au sein des sciences de l’information et de la communication, avec l’étude de cas d’une application numérique démarrée en 2009 et qui a initiée une nouvelle classe de plateformes, à savoir respectivement Bitcoin et les cryptomonnaies.

Our research starts from the empirical observation of the omnipresence and the permanent extension of the digital techniques in various domains of the contemporary social life, and that these techniques spread all over the place since the turn of the 1960s. At that time, their design and development was carried out with a view to improving the productivity of very specific computational tasks in the scientific, military and statistical fields. This observation of a digital surge leads us to question its dynamics, particularly in relation to those of commodity production which constitutes the particular context of its advent. Our approach is to design a socio-technical model of computing that can account for these features and which is based on a formal analysis of the properties of the machine at the heart of computing, namely the computer, which wecharacterize by the simultaneous abstract and concrete forms of its running. After having set up the theoretical framework in which the meeting between digital and capital can be grasped, it will be for us to propose a test of this framework on objects that animate the debates today in the information and communication sciences, with the case study of Bitcoin, a digital application started in 2009 and which initiated cryptocurrencies as a new class of platforms.
