Studies of legitimacy have typically looked at the creation and maintenance of legitimacy by both established and new organisations. This paper looks at how a set of entrepreneurs use the legitimacy of one, Alternative, community as a scaffold to build legitimacy in a more Mainstream one, despite the fact that norms between the two were often contradictory. Studying Bitcoin entrepreneurs in Europe, we find that the distributed, digital community of Bitcoin operates as a kind of MNC: the larger decentralised (and Alternative) community acts as the headquarters, while the local entrepreneurs seeking Mainstream legitimacy behave like subsidiaries. This allow them to rely on the legitimacy of the community at large, while simultaneously distinguishing themselves from the broader Bitcoin community as they seek legitimacy.
Technology innovation and new consumers’ habits are fostering two interesting experiences in the payments’ landscape: the increasing use of mobile payment instruments and the emergence of alternative payment schemes without fiat or banking money, like Bitcoin. This contribution considers both cases as useful drivers for innovation, but at present their positive outcomes are unclear. A synthetic economic analysis highlights costs and benefits for consumers and third-party operators, arguing that mobile payments could improve competition and force banks to rethink their strategies. More controversial issues concern bitcoin: on this topic enthusiastic expectations of financial operators are jointly considered with cautious positions expressed by regulatory and monetary authorities. Recent tendencies in Bitcoin’s informal infrastructure are confirming that an effective decentralized and peer-to-peer payments system is rather hard to build.

Tema ovog rada su kriptovalute. Budući da većina ljudi nije pravodobno upoznata s ovom temom, ovaj rad prikazuje i opisuje kriptovalute te način na koji se upotrjebljuju u svakodnevnom životu. Kriptovalute (eng. cryptocurrency) digitalne su valute dizajnirane kao sredstvo razmjene. Poznate su po tome što su državne agencije i banke isključene iz procesa razmjene. Kriptovalute omogućuju jednostavnu, jeftinu i brzu transakciju na području cijeloga svijeta. Trenutno najisplativije kriptovalute su Bitcoin i Ethereum, a u radu je opisana njihova korisnost, prednosti i mane. Budući da se Bitcoinu predviđa uspješna budućnost i sve je prisutniji i prihvatljiviji na tržištu, u radu su navedeni primjeri iz Hrvatske koji to potvrđuju. Sve veći broj poduzetnika odlučuje se za uvođenje kriptovaluta. U primjerima je obuhvaćen širok spektar djelatnosti, od frizerskih usluga, preko raznih tvrtki koji se bave prodajom računalne opreme, ugostiteljskih usluga preko mogućnosti brzog i lakog podizana gotovine na kripto bankomatima pa sve do plaćanja komunalnih usluga, pa čak i humanitarno djelovanje. Mnogi smatraju da su kriptovalute samo sinonim za prijevare i pranje novca, no programeri tvrde da su kriptovalute samo jedna vrsta tehnologije, alat koji sam po sebi ne može biti ni dobar ni loš, ovisno o tome za što se koristi. Autor ovoga rada proveo je istraživanje o tome kako se može besplatno započeti trgovanje kriptovalutama te je anketom ispitao stavove ispitanika o implementaciji kriptovaluta u društvu.
In this article, we review the recent developments in the digital currency landscape. We survey the economic drivers that led to the creation of digital currencies and show that they are a natural step in the evolution of means of payment. We overview two major classes of digital currencies, cryptocurrencies and platform-based digital currencies and discuss how the design of such currencies affects the incentives of their users and ultimately their popularity. Finally, we discuss competition in the digital currency market.
This paper reports the outcome of a series of interviews and focus group meetings with professionals working in post-trade processing and the provision of mutual distributed ledger services. The objective was to elicit and document views on three research hypotheses about the potential impact of mutual distributed ledger technology (‘blockchain’) on post-trade processing global securities markets. \n\nThese hypotheses are (a) on the appropriate access to mutual distributed ledger; (b) on whether change would be piecemeal or ‘big bang’; and (c) on the extent to which applying mutual distributed ledger in securities settlement would require major changes in business processes. Our research finds that while the use of blockchain to validate operational data in mutual distributed ledgers can yield substantial reductions in both cost and risk, the concept of data sharing itself is far from new. Current interest in mutual distributed ledgers has established significant momentum, but there is a danger of building unrealistic expectations of the extent to which the technology on its own will address the underlying need for co-ordination of business processes both within and between firms. Achieving all the potential benefits from mutual distributed ledgers will require board level buy-in to a substantial commitment of time and resource, and active regulatory support for process reform, with relatively little short term payoff.

This paper explains the functioning of “blockchain technology” and critically assesses its potential role in improving services in banking, contracts, and database systems. Comparing blockchain to the current best practice technology in these fields reveals several barriers to successful commercial implementation: Blockchain technology involves costly redundancies and irreversibility, faces serious scaling problems and significant barriers to complying with regulations, and is a security liability unless secured with its own freely trading currency. A survey of the state of the blockchain industry shows that in eight years since blockchain technology was invented, it has had no commercial applications other than digital cash. The paper concludes that a blockchain is a peculiar engineering design whose only advantage is in removing third party intermediation to allow for the creation of digital cash, and is unlikely to offer economic advantages for any commercial problem other than the one it was specifically engineered to solve.

The blockchain (i.e., a decentralized and encrypted digital ledger) has the potential to disrupt many traditional business models. This study investigates the emerging blockchain business-application landscape by analyzing its industry, venture capital funding, and regional distribution. By matching four venture databases on blockchain-based startups we create a unique database to analyze the technology from a diffusion of innovation theoretical perspective. First, our results show that blockchain startups are present across all industry segments and are most prominently represented in the Finance & Insurance and Information & Communication industries. A fine-grained analysis of financial services yields increasing novel applications in existing service offerings. Second, we find that mainly Finance & Insurance and Information & Communication industries are funded by venture capital, but that blockchain startups are present across all industries. Third, our regional distribution analysis of the emerging ventures identifies two leading geographical blockchain clusters (i.e., the US and UK).
Distributed ledgers, and in particular blockchain technologies, promise to be revolutionary to financial markets, and the uptake of Bitcoin shows that it can also influence wider society. This paper examines the suggested uses of the technology, as well as the possible regulatory concerns that the technology raises. It looks at various regulatory measures that have been developed by jurisdictions to combat it, as well as possible applications of current regulatory frameworks. The paper then frames the issues in a regulatory lens, and looks at what lessons can be learned for regulation going forward.
Abstract Since the emergence of the virtual currency Bitcoin in 2009, a new, Internet‐based way of recording entitlements and enforcing rights has increasingly captured the interest of businesses and governments. The technology is commonly called ‘blockchain’ and is often associated with a closely related phenomenon, the ‘smart contract’. The market is now exploring ways of using these concepts for financial assets, such as securities, fiat money and derivative contracts. This article develops a conceptual framework for the governance of blockchain‐based networks in financial markets. It constructs a vision of how financial regulation and private law should set the boundaries of this new technology in order to protect market participants and societies at large, while at the same time allowing the necessary room for innovation.
Cryptocurrencies record transactions in a decentralized data structure called a blockchain. Two of the most popular cryptocurrencies, Bitcoin and Ethereum, support the feature to encode rules or scripts for processing transactions. This feature has evolved to give practical shape to the ideas of smart contracts, or full-fledged programs that are run on blockchains. Recently, Ethereum's smart contract system has seen steady adoption, supporting tens of thousands of contracts, holding millions dollars worth of virtual coins. In this paper, we investigate the security of running smart contracts based on Ethereum in an open distributed network like those of cryptocurrencies. We introduce several new security problems in which an adversary can manipulate smart contract execution to gain profit. These bugs suggest subtle gaps in the understanding of the distributed semantics of the underlying platform. As a refinement, we propose ways to enhance the operational semantics of Ethereum to make contracts less vulnerable. For developers writing contracts for the existing Ethereum system, we build a symbolic execution tool called Oyente to find potential security bugs. Among 19, 336 existing Ethereum contracts, Oyente flags 8, 833 of them as vulnerable, including the TheDAO bug which led to a 60 million US dollar loss in June 2016. We also discuss the severity of other attacks for several case studies which have source code available and confirm the attacks (which target only our accounts) in the main Ethereum network.
The decentralized digital currency Bitcoin - and its underlying "blockchain" technology - has created much excitement in the technology community, but its potential for building truly empowering social and solidarity-based finance has yet to be tested. This paper provides a primer on the basics of Bitcoin and discusses the existent narratives about the technology´s potential to facilitate remittances, financial inclusion, cooperative structures and even micro-insurance systems. It also flags up potential points of concern and conflict; such as the tech-from-above "solutionism" and conservative libertarian political dynamics of some of the technology start-up community that surrounds Bitcoin. As a way of contrast the paper considers "blockchain 2.0" technologies with more overtly communitarian ideals and their potential for creating "cooperation at scale". It concludes with suggestions for future research.
The new technology Bitcoin has got a lot of attention since it was presented in late 2008 and implemented early 2009. However, the main attention has been to the currency and not so much the underlying blockchain technology. This paper argues that we need to look beyond the currency and investigate the potential use of the blockchain technology to enable smarter governments by utilizing the secure, distributed, open, and inexpensive database technology. The technology is discussed in the perspective of an information infrastructure to investigate its full potential. After a literature review of Bitcoin publications, with a special emphasis on eGovernment literature, the paper presents a relevant use case highlighting the innovation potential of the new technology. The literature review shows that Bitcoin is absent from the e-Government literature. The use case presented shows that Bitcoin could be a promising technology for validating many types of persistent documents in public sector.
Over recent years, the innovative decentralized payment system Bitcoin has received much attention in practice and academia. Despite a growth of transaction volume and an increasing attention in the area of e-commerce, there is little academic research examining the factors influencing adoption. To fill this research gap, this paper documents an exploratory study of the key determinants and inhibitors of Bitcoin use. Drawing upon the Technology Acceptance Model and a literature review, we integrate various benefits and risks of Bitcoin use to form the multidimensional constructs Perceived Benefit and Perceived Risk. We propose and empirically test a theoretical model that explains the use of Bitcoin as an online payment system for legitimate purchases and money transfers. Furthermore, we recognize several conceptual and methodological development potentialities for technology acceptance theories in the context of decentralized and sharing economy systems.
At the World Economic Forum more than 800 executive and technology experts were asked when they thought a particular “tipping point” would be reached – when would we see a government collect tax with blockchain? The agreed date was 2023 (on average). A full 73% of the respondents however, expected the tipping point to have been reached by 2025. This paper argues that the EU VAT will be an early adopter, if not the earliest adopter of blockchain. There are a number of reasons why. Blockchain will bring substantial efficiencies to VAT collection. It will reduce costs, and build critical inter-governmental trust relationships. Most importantly, blockchain will immediately end revenue losses well in excess of €50 to €60 billion per year in missing trader intra-community fraud (MTIC). Blockchain will also be essential for making the EU Commission’s April 2016 Action Plan on VAT work. Blockchain should be a critical part of the detailed legislative proposal (expected in 2017). This plan will bring in a “definitive VAT system” dealing with intra-EU cross-border trade, which will be based on taxation in the country of destination. This paper predicts that the EU will bring in the “definitive system” on the back of blockchain technology. Blockchain is a revolutionary improvement on any centralized data system. Tax administrations are inherently based upon centralized repositories of taxpayer data. They are prime candidates for the kinds of efficiency improvements that come through blockchain. This is particularly the case for transaction taxes, and even more so for a VAT fraud prevention application, like the Digital Invoice Customs Exchange (DICE), which relies on a real-time exchange of encrypted data.
Over the last decade, information technology has contributed significantly to the evolution of financial markets, without, however, revolutionising the way in which financial institutions interact with one another. This may be about to change, as some market players are now predicting that new database technologies, such as blockchain and other distributed ledger technologies (DLTs), could be the source of an imminent revolution. This paper analyses the main features of DLTs that could influence their potential adoption by financial institutions and discusses how the use of these technologies could affect the European post-trade market for securities. The original protocol underlying DLTs has its roots in the anarchic world of virtual currencies, which operate outside the conventional financial system. The public debate on DLTs has also been very much focused on the revolutionary potential of the technology. This paper concludes that, irrespective of the technology used and the market players involved, certain processes that feature in the post-trade market for securities will still need to be performed by institutions. DLTs could, however, stimulate a reorganisation of financial markets, which could in turn: (i) reduce reconciliation costs, (ii) streamline the post-trade value chain, and (iii) allow more efficient use to be made of collateral and regulatory capital. It should, nevertheless, be remembered that research into DLTs and their uses is at an early stage. The scope for financial institutions to adopt DLTs and their potential impact on mainstream financial markets are still unclear. This paper discusses three potential models of how market players could adopt DLTs for performing core post-trade functions. The DLT could be adopted either: (i) in clusters, (ii) collectively, or (iii) peer to peer. The evaluation of the three adoption models assumes that they are all equally compatible with the regulatory framework. It shows that, assuming this to be the case, they would each have different advantages and costs. JEL Classification: G21, G23, L15, O33

Distributed ledger technology, invented for cryptocurrencies, is increasingly understood as a new general-purpose technology for a broad range of economic activities that rely on consensus of a database of transactions or records. However, blockchains are more than just a disruptive new ICT. Rather, they are a new institutional technology of governance that competes with other economic institutions of capitalism, namely firms, markets, networks, and even governments. We present this view of blockchains through a case study of Backfeed, an Ethereum-based platform for creating new types of commons-based collaborative economies.
