The objective of this research is to provide the reader an overview of the distributed ledger technology (DLT), its fundamental challenges, the current and potential future uses in the financial industry, and to suggest future fields of the topic to be researched. The first task of this thesis is trying to answer, âhow will the distributed ledger technology impact the financial industryâ. Although the thesis will not cover exhaustively all the financial industryâs needs towards the distributed ledger technology, it will give an overview of the DLTs probable usage in the industry. By reading the thesis and especially its use cases from the fields of private equity, and settlement and clearing of public securitiesâ trading, the reader should get a more accurate answer to the secondary question âhow can the public securities and private equity markets use distributed ledger technology in the near futureâ. The question about the distributed ledger technologyâs impact on the whole market is complicated. Despite the amount of financing this technology has acquired in the recent years, there are no new, disruptive or widespread usages for the DLT in the financial industry. However, it is expected that during the next five years, the DLTs become reality. This is due to their enormous potentiality in security, efficiency and automation, which all could save the financial industry up to 50% of their current costs. Additionally, during the same time period, it is highly expectable that some financial service applications, basing on the DLT, will be presented for the consumers by the players from outside the traditional markets. To answer the secondary question, the both markets will face significant changes during the upcoming years: public securitiesâ post-trade processes will benefit from the more secure and rapid settlement, whereas the private equity marketâs whole nature can become a more accessible for both the investors and the businesses seeking for financing.

Currently, business processes become more and more complicated. Data used in these processes circulates mainly through the digital communications. Due to these conditions some kind of electronic contracts for business deals becomes necessary. Smart contracts should describe a set of conditions, implemented through some events in the real world and digital systems. The most important requirement for this technology is privacy ensuring. In this work we have explored existing projects of privacy-preserving smart contracts, defined comparison criteria, compared projects and made a conclusion about options required for smart contract frameworks.

This paper explains the main features of and motivation for the âreport onceâ demonstrator1 shown at the 2017 Data For Policy conference. It shows how Ethereum2 smart contracts, based on the semantics and algorithmic representations defined in ACTUS3 can implement âdigital doppelgängersâ of financial contracts. <br> <br> The implementation makes use of a private4 Ethereum blockchain, with smart contracts written in Solidity.5 The limitations of using ACTUS in a semi real-time scenario are explored, as well as how to overcome these limitations. <br> <br> The major innovation, visualized by the demonstrator, is that compliance reports can be generated in semi realtime, using the information present in the âdigital doppelgängersâ, residing in the blockchain. <br> <br> The demonstrator supports various use cases, illustrated through the narration of stories. In these stories, Alice, Bob and Eve are contracting parties, Romeo acts as regulator, and the narrator tells the stories. The stories cover trading a Bond, trading an Interest Rate Swap (IRS), the defaulting of a party (i.e. a payment stop), and various types of regulatory reports. <br>

Blockchain technology allows the creation of distributed ledgers. These distribute control among the players rather than requiring a centralized database, and so can reduce costs and speed-up transactions. However, when it is used for assets which exist outside the blockchain itself, an unmodified adoption of the technology would bypass legal and regulatory requirements which, for these kinds of assets, cannot be bypassed without fundamental change to the law. Building those requirements into any blockchain-based system introduces features which are not necessary for performing its core functions, and we call these âlegal impuritiesâ. The most important legal impurities required are those relating to identification of the parties, and introducing the ability of a trusted third party to make modifications to the ledger. Not only does introducing these legal impurities make fundamental changes to the concept behind blockchain, but it is also essential that they are implemented in ways which do not threaten the integrity of the blockchain as evidence.

Cryptocurrencies allow users to securely transfer money without relying on a trusted intermediary, \nand the transparency of their underlying ledgers also enables public verifiability. This openness, \nhowever, comes at a cost to privacy, as even though the pseudonyms users go by are not linked to their \nreal-world identities, all movement of money among these pseudonyms is traceable. In this paper, \nwe present M¨obius, an Ethereum-based tumbler or mixing service. M¨obius achieves strong notions of \nanonymity, as even malicious senders cannot identify which pseudonyms belong to the recipients to \nwhom they sent money, and is able to resist denial-of-service attacks. It also achieves a much lower \noff-chain communication complexity than all existing tumblers, with senders and recipients needing \nto send only two initial messages in order to engage in an arbitrary number of transactions.
Best known for their role in the creation of cryptocurrencies like bitcoin, blockchains are revolutionizing the way technology entrepreneurs finance their business enterprises. In 2017 alone, tech entrepreneurs raised over $6 billion through the sale of blockchain-based digital tokens, with some sales lasting mere seconds before selling out. In a token sale, also referred to as an âinitial coin offeringâ or âICO,â organizers of a project sell digital tokens to members of the public to finance the development of new technological platforms and services. After the initial sale, cryptocurrency exchanges scattered across the globe list tokens for trading and facilitate an active secondary market in which wild price fluctuations are common.\nThe recent explosion of token sales could mark the beginning of a broader shift in public capital markets. Blockchains drastically reduce the cost of exchanging value and enable anyone to transmit digitized assets around the globe in a highly trusted manner, stoking dreams of truly global capital markets that leverage the power of a blockchain and the Internet to facilitate capital formation. Lacking homogeneity, the status of tokens under U.S. securities laws is unclear. Although the SEC recently issued a Report of Investigation and has initiated several enforcement actions in which it has found that tokens are securities, confusion still surrounds the boundaries between the types of tokens that will be treated as securities and those that will not.\nIn this Article, we argue that the SEC and Congress should provide token sellers and the exchanges that facilitate token sales with additional regulatory certainty and a sensible path to compliance. Specifically, we outline extrinsic and intrinsic factors that courts and regulators should consider when applying the Howey test to digital tokens, adoption of which would help resolve the uncertainty surrounding tokens that mix aspects of consumption and use with the potential for profit. We further propose that lawmakers adopt both a compliance-driven safe harbor for online exchanges that list tokens with a reasonable belief that the public sale of such tokens is not a violation of section 5 of the Securities Act of 1933 as well as an exemption to the section 5 registration requirement that has been tailored to digital tokens.
Abstract Distributed ledger technology, a variant of which is blockchain technology, represents one of the most important innovations of the FinTech revolution. Academics, policy-makers, and market participants are experimenting with the technology with the aim of enhancing the functioning of financial markets. Industry consortia are being formed by the biggest financial institutions in the world seeking to leverage the use of the technology, in order to improve the clearing and settlement process. Furthermore, central banks in advanced and developing economies are examining the potential of using the technology in market infrastructures operated by central banks and are even exploring the possibility of issuing digital base money. Nevertheless, the widespread adoption of distributed ledger technology as envisioned by its ardent supporters encounters considerable legal obstacles, including the numerous new regulations imposed on financial markets and market participants in the aftermath of the Global Financial Crisis. This chapter seeks to disentangle the myths from the realities of the so-called distributed ledger technology or blockchain revolution and discusses how the legal regime can act both as an impediment and a catalyst to the widespread adoption of the technology.
This article analyses the existing institutions and infrastructure for payments. Authoritative settlement based on central bank support is seen as being essential for both large value and retail payment systems; and, in the EU, UK, and US, the importance of regulating for the protection of consumers who use retail payment systems is recognised. In this institutional context, payment innovations (including Bitcoin and distributed ledger or autonomous organisation technologies) are assessed. It is suggested that, while competition at certain levels is likely to bring social benefits through commercial developments, the maintenance of public interest objectives necessarily delineates the scope of competition. While this might limit the disruptive impact of payment innovations, it is argued that, in the light of the public policy needs for a stable and efficient public infrastructure and the social needs of confidence and trust in a predictable and regulated payment system that meets commercial and social expectations such as in consumer protection, this is not necessarily undesirable.
Abstract This paper aims to propound a thorough and circumspect analysis of the implications of blockchain technology in the accounting profession and its broader industry. The analysis begins with a summary of early developments by first movers and how they are harnessing blockchain technology to improve business practices. Concomitantly, the paper will go on to discuss how this technology will streamline accounting processes, specifically as the technology approaches critical mass. Finally, a discussion of its longâterm implications will follow through a more philosophical and conceptual dialogue. Throughout the paper, criticisms will be raised to address concerns regarding blockchain's widespread use.
Abstract Smart contracts on a blockchain behave exactly as specified by their code. To be sure that a smart contract behaves as expected, the end-user has to either analyze its code or trust a potentially anonymous developer or auditor to do so. This approach proposes a smart contract deployment and management platform that can execute development tools and code quality tools in a trusted way and uses this to reduce the trust required into the smart contract developer or auditor. Additionally, such a platform can provide new capabilities for developers aiding them in the creation of smart contracts.

In this paper, we present Velocity, a decentralized market deployed on Ethereum for trading a custom type of derivative option. To enable the smart contract to work, we also implement a price fetching tool called PriceGeth. We present this as a case study, noting challenges in development of the system that might be of independent interest to whose working on smart contract implementations. We also apply recent academic results on the security of the Solidity smart contract language in validating our codes security. Finally, we discuss more generally the use of smart contracts in modelling financial derivatives.
An appealing feature of blockchain technology is smart contracts. A smart contract is executable code that runs on top of the blockchain to facilitate, execute and enforce an agreement between untrusted parties without the involvement of a trusted third party. In this paper, we conduct a systematic mapping study to collect all research that is relevant to smart contracts from a technical perspective. The aim of doing so is to identify current research topics and open challenges for future studies in smart contract research. We extract 24 papers from different scientific databases. The results show that about two thirds of the papers focus on identifying and tackling smart contract issues. Four key issues are identified, namely, codifying, security, privacy and performance issues. The rest of the papers focuses on smart contract applications or other smart contract related topics. Research gaps that need to be addressed in future studies are provided. http://aircconline.com/ijcsit/V9N5/9517ijcsit11.pdf
Cryptocurrency, most notably Bitcoin, has continued to attract attention and consequently substantial investment from businesses, consumers, and the media. Understanding what drives consumer adoption of the technology, however, is not understood. This study uses the UTAUT2 technology adoption theory in order to fill this research gap. A conceptual model is built through a review of the technical aspects of cryptocurrency, an analysis of the technology as currency, and finally a review of technology adoption theory to date. UTAUT2 is found to be the most appropriate adoption theory directly dealing with consumer context. The model conceptualised is tested using multiple linear regression analyses on primary survey data. The findings indicate that facilitating conditions have the highest explanatory effect on actual usage ahead of behavioural intention to use cryptocurrency. Behavioural intention was predicted most strongly by hedonic motivation, followed by perceived trust, and social influence. Interestingly, effort expectancy and performance expectancy were found to be non-significant, contrary to much of the studies in related fields. The study also aimed to identify the primary use-case finding that investment was the primary consumer use. Due to characteristics of the sample collected, the studyĂs findings are limited to the South African context.
