In this paper I discuss how blockchains potentially could affect the way credit risk is modeled, and how the improved trust and timing associated with blockchain-enabled real-time accounting could improve default prediction. To demonstrate the (quite substantial) effect the change would have on well-known credit risk measures, a simple case-study compares Z-scores and Merton distances to default computed using typical accounting data of today to the same risk measures computed under a hypothetical future blockchain regime.
Compared to initial public offerings (IPOs) that are sales of company ownerships, and loans that are sales of debt claims, initial coin offerings (ICOs) are sales of promises of cryptocurrency appreciation. However, regulatory uncertainties continue to prohibit successful widespread adoption. This paper examines ICOs with varying levels of success, including Mastercoin (now Omni) and Kin, as well as fraudulent ICOs, like REcoin and OneCoin. The discussion of the benefits and flaws within the ICO market examines regulatory challenges concerning risks transferred to investors through information asymmetry, while questioning the ability of regulations to enhance investor protection mechanisms without undermining the fundamental value of cryptocurrencies and ICOs as a viable funding structure.
The article aims to bring to light the limits and contradictions of cryptocurrencies, as well as to investigate possible alternative uses of them. Particularly focusing on Bitcoin, understood as a benchmark for the entire sector, the authors seek to answer the following questions: Should Bitcoin be considered a currency, an investment vehicle, or a speculative asset? On which factors does Bitcoin volatility depend? Do Central Banks effectively have no power to influence/stabilize Bitcoin volatility? Following the empirical strategy proposed by Baek and Elbeck, the article shows that Bitcoin returns merely depend on financial conventions and that the cryptocurrency is acting as a highly speculative asset. Sociotechnical innovations introduced by Bitcoin, the authors argue, have concretely opened the possibility of deeply rethinking money. However, several factors are currently negatively affecting the possibility of the cryptocurrency to function as an effective means of payment. Whether this experience can pave the way for the birth of new and more democratic monetary instruments, as the article discusses, is an issue that calls into question a whole combination of political, technical and social elements.
The theoretical foundations of bitcoin have been frequently traced back to the Austrian school of economics. To the extent that cryptocurrencies are not issued by a centralized authority and do not rely on an official legal tender status for their acceptance, they may indeed appear as a dramatic departure from the historical trend that has led, over the past few centuries, to the making of national money and as a decisive step toward the “denationalization of money” advocated by F. A. von Hayek. This article investigates to what extent bitcoin truly embodies the principles of stable money prescribed by Hayek and whether the proliferation of cryptocurrencies constitutes a Hayekian monetary competition.
Cryptocurrencies aim at substituting the operations of trusted financial institutions with decentralized operations, including the monetary functions provided by central banks. This article addresses some fundamental questions. Can cryptocurrencies, with no institutions behind them, really function as useful money? Can cryptocurrencies improve our payment system? What are the risks? And how should central banks and other policy makers respond to cryptocurrencies? <b>TOPICS:</b>Currency, portfolio construction, wealth management
Blockchain ilk defa 2009 yılında ortaya çıkan bir alt yapı teknolojisi olsa da finans dünyası tarafından keşfedilip araştırılmaya başlanması 2014 yılının ilk aylarını bulmuştur. Bugün gelinen noktada, mevcut ekonomik ve iş modellerini bozma gücüyle radikal bir inovasyon olduğunu ispatlamış, yeni ve heyecan verici bir teknoloji olduğu söylenebilir. Finans sektöründen enerji piyasalarına, tedarik zinciri süreçlerine, fikri mülkiyet yönetimine, kamu sektörüne ve bunlar gibi çok çeşitli alanlara verimlilik artışı sağlama potansiyeline sahiptir. Blockchain teknolojisi sağladığı tam otomatik, şeffaf, güvenli ve minimum aracı alt yapısı ile pek çok sektörün ve devletin ilgisini çekmektedir. Yapılan bu çalışmada Blockchain’in taşıdığı potansiyelin daha iyi anlaşılabilmesi için uygulama alanlarına genel bir bakış ile Türkiye’nin bu teknolojiye olan yaklaşımı incelenmiştir.

Abstract This chapter considers whether the principles and practices employed by traditional banks may be reconciled with the trading and holding of Bitcoin and other cryptocurrencies. It examines three basic functions of traditional banking — storing value, making payments and lending — and the extent to which they can be performed through cryptocurrency transactions. In analysing the extent to which cryptocurrencies operate as stores of value, the chapter asks whether a cryptocurrency itself stores monetary value and how the economic value in cryptocurrencies is stored in digital wallets. It also discusses four duties that arise from drawing an analogy between digital wallets and bank accounts in the context of bank-customer relationships: the duty to act in accordance with one's mandate; the duty to keep information confidential; the duty to act with reasonable skill and care; and the fiduciary duties (or disabilities) relating to unauthorised conflicts of interest and profit-making.
Weaknesses in investor control over their investments and in warehousing systemic risk in modern Financial Market Infrastructure (FMI) are the result of a combination of market failures and of structural flaws deeply ingrained in modern financial markets. Yet the utility of complex FMI comprising long custodial chains and large global Central Counterparties (CCPs) for the operation of modern markets is not seriously disputed. The change in the technology paradigm with the introduction of DLT systems for securities and derivatives FMI can increase investor control, the efficiency of risk management and, to some extent, augment the distribution of systemic risk. It can thus create a more diverse and resilient financial ecosystem. This cross-disciplinary paper identifies a multitude of reasons that favour a paradigm shift in FMI technology. It also sketches a comprehensive blockchain-based framework for the development of permission-based platforms for derivatives clearing and settlement and the handling of liquidity shortages within DLT systems. Arguably, the impact of technological change should lead to a reduction of industry rents for the benefit of end investors and of the end users of finance (entrepreneurs and businesses) enhancing market welfare. Therefore, the use of blockchain technology in FMI can transform the structure and future direction of the financial services industry as a whole.
This Note recommends a viable way for the Securities and Exchange Commission (SEC) to apply the Regulation S foreign-issuer safe harbor to Initial Coin Offerings (ICOs). In the last two years, cryptocurrencies and blockchain-based companies have witnessed dramatic rises in price and value. New entrants to the crypto-markets often use ICOs as virtual public offerings to earn capital and develop their projects. The SEC has signaled that they plan to fold ICOs and blockchain offerings into existing securities law. How these new virtual capital-raising mechanisms will fit into this framework is still largely unknown. As a defensive measure, many ICOs have banned US investors in an attempt to become foreign offerings that are outside the SEC's reach. Regulation S is the existing safe harbor that conventional securities offerings utilize to ensure that they are "foreign offerings." While ICOs are novel and do not fit perfectly into Regulation S's language, the safe harbor can be adapted to appropriately set parameters for ICOs. This Note suggests the correct interpretation that both protects US consumers and sets acceptable requirements for corporations seeking to fall within Regulation S.
High-tech enables payment evolution and global competition. The ambiguities surrounding of the digital currency still leave enough space for the analysis of its unreserved acceptance, trust and anticipation, which are the main driver for the spread of the network. Banks should carefully consider the technology underlying these cryptocurrencies as a potential generic new way of transferring ownership of the value over the long term. The chapter provides an analysis of the use of cryptocurrencies in general, especially Bitcoin as the technology adoption in the presence of network externalities. The objective attitude is the future of the digital currency in the moment is still unsolved issue due to the existence of “critical mass”. Further, the chapter explores financial privacy which is very sensitive issue in using digital currency (or cryptocurrency) and discuss about private choices versus political rules. The research has shown that the future of cryptocurrencies can be bright if some institutional-formal conditions are met due to the fact that success evolution of e-money requires building safety payments through three criteria–standardization, compatibility and innovation.

It is argued here that because a cryptocurrency has no intrinsic value, problems relating to day-to-day valuation and pricing arise. It is shown how these lead to the reversal of the conventional relationship between supply and demand and the susceptibility of the cryptocurrency markets to irrationality and speculative bubbles arising from the herding instinct. Also, as the cryptocurrency markets are largely free of regulation and the desire for privacy by founders, owners and developers is so great, accountability and disclosure requirements are either minimal or non-existent, leading to the manipulation of cryptocurrency prices, volume and market capitalisation information. Another consequence of their freedom from regulation, particularly surprising given the importance placed on their security through the use of blockchain, is the magnitude of thefts of cryptocurrency (both in terms of frequency and size) levels of which would neither be expected nor tolerated in regulated financial markets.
Since Bitcoin was introduced in 2008, blockchains have established as a tool for speculation as well as decentralized applications. In 2014, Ethereum, a so-called second-generation blockchain, introduced the concept of smart contracts, which allows the decentralization and disintermediation of a wide range of use cases and industries. In the context of financial instruments or securities, smart contracts allow increased transparency, liquidity, availability, and auditability, while significantly reducing the barrier to entry for potential investors. In recent months, numerous projects and standard proposals have aimed to facilitate the tokenization of securities. However, regulatory compliance imposes a major challenge for security token platforms. Current realizations of legally required user verifications lack scalability, flexibility, and reusability. Furthermore, potential investors are confronted with tedious redundant processes to disclose private data per investment opportunity. We address these challenges by proposing a smart contract architecture that generally solves legal compliance. Immutable logic, the upgradability of compliances, as well as structuring evaluation logic in hierarchies allow the realization of arbitrary regulatory clauses. Our design addresses both the primary and secondary market, and can easily be extended, e.g. to allow secondary offerings or legal enforcement. Furthermore, we envision a network of trust realized via identity management on the blockchain. Hereby, conventions between platforms, regulators, and exchanges fully automate legal checks throughout atomic transactions on the Ethereum blockchain. Furthermore, we use so-called oracles to bridge blockchain-based logic with regulatory definitions, e.g. investment limits in Euro. We compare our proposal to existing implementations and extensively discuss design decisions. Furthermore, we evaluate our proposal with exemplary use cases. Specifically, we fully implement a fictive compliance to demonstrate general concepts, as well as evaluate real-world challenges derived from legal frameworks. Our work aims to complement existing work related to security token in order to accelerate the adoption of asset tokenization.
Günümüzde teknolojinin hızla gelişmesi hayatımıza birçok alanda yenilik getirmeye başlamıştır. Özellikle finansal açıdan yenilikler hayatımızı direkt olarak etkilemektedir. Yapılan mal veya hizmet harcamaları internet üzerinden yapılmaya başlanmış olması geleneksel ödeme yöntemlerini değişikliğe uğratmış ve elektronik ödeme yöntemlerini hayatımıza sokmuştur. Bununla beraber geleneksel paralar evrimleşerek sanal paralara dönüşmüştür. Sanal para olgusu 2009 yılında Nakamoto isimli kimliği henüz belli olmayan kişi ya da kuruluş tarafından çıkarılmış bitcoin isimli bir para birimi ile hayatımıza girmiş olup günümüzde popülerliğini arttırarak devam etmektedir. Blok zinciri teknolojisine sahip olan bu para birimi tamamen sanal olarak ve herhangi bir kuruluşa bağlı olmaksızın tarafların birbirine para transferleri yapmalarına imkân tanımaktadır. Bu para birimi devletlerce çıkarılmadığından dolayı para arzı, madencilik denilen bir süreç ile çıkmakta olup bir kişi ya da kuruluş fark etmeksizin gerekli donanım ve yazılım ile isteyen herkes bu para biriminin arzını sağlamaktadır. Herhangi bir kuruluşa bağlı olmadığı için de devletler bu paralar ile alakalı düzenlemeler getirmeye ve bazı ülkeler kontrolleri dışı geliştiğinden dolayı bu para birimini kullanımı yasaklamaya çalışmaktadır. Bu bağlamda, bu çalışmada finansal yenilikler ele alınmış özellikle elektronik ödeme yöntemleri ve sanal para olarak bitcoin üzerinde durulmuştur. Çalışmada konu ile ilgili literatür taranmış olup, sanal para kavramı açıklanmış, bu paranın kullandığı günümüzün en yeni teknolojisi olan blok zinciri ele alınmış, sanal para madenciliği ve bu paraya getirilen eleştiriler açıklanmıştır. Sonuç olarak hızla gelişen teknolojiye karşı koyulamayacağı için finansal açıdan değişikliklere hızlı cevap verilmesi ve bu yeniliklerden doğan avantaj ve dezavantajlar iyi belirlenmelidir.
Bitcoin is a tremendously debated phenomenon in the world of finance and in recent the scientific literature on the topic has expanded. In this thesis,the bitcoin to US dollar exchange rate is examined through various conditional variance models to describe its highly volatile nature. We examine whether the introduction of bitcoin futurescontractsin late 2017 has had a decreasing impact on price volatility by estimatingthe unconditional variance. The log-return of the bitcoin exchange rate is analysed,and there is evidence of volatility clustering and time-varying volatility. Consequently, the variance is modelled through the GARCH(1,1), EGARCH(1,1) and GJR-GARCH(1,1) modelswith innovations followingthree distributions. The in-sample selection method selectedthe EGARCH(1,1) model where innovation terms follow a generalizederror distribution as the most parsimonious model. The findings show that volatilityhas not decreased after the introduction of bitcoin futures on regulated exchanges. \nKeywords: Bitcoin, conditional variancemodelling, bitcoin futures, price volatility exchange rate, statistical analysis
Security Token Offerings (STOs) are a very recent phenomenon that has started to replace the Initial Coin Offering (ICO) one for financing companies through blockchain networks. Contrary to ICOs, which are based on “utility tokens”, STOs issue “security tokens” that are likely to achieve revenues in the same way that bonds or shares do. However, because they utilize the blockchain network, they are expected to benefit from lower intermediary and transaction costs. The objective of this paper is to examine, for the first time in financial research, to what extent this nascent market can become a liquid one, adapted for small and medium-sized enterprises (SMEs). To address this still unexplored issue, we proceed in two stages. First, we develop the technical characteristics of security tokens. Then, we analyze the trading volumes of a very few ones, although it has proved difficult to conduct a relevant empirical analysis. Our results are that, as for ICOs, the technical nature of security tokens can greatly facilitate their listing and exchange. However, there are significant disparities in their use and, for the moment, most of them remain locked in the wallet of so-called accredited investors. As a result, the potential of the blockchain-based equity market is still uncertain: STOs are likely to represent a growing and liquid alternative to IPOs, private equity and crowd funding to finance SMEs. Nevertheless, the liquidity of their digital assets strongly depends on the quality of their issuers and on the existence of specialized trading platforms.
Smart contracts are the key component in Ethereum. They hold the logic to be executed on the network, keep track of their own state, and can interact with other smart contracts as well. However, they have some limitations, such as limited computation per transaction and expensive storage costs. They also cannot initiate new transactions – they depend on external accounts to trigger them. And since they run on the Ethereum network, they cannot directly interact with anything outside it. In this chapter, we will
