This paper explores how entrepreneurs can use fungible tokens—whereby they issue digital assets and commit to only accept those tokens as payment for future products or services—to fund venture development. We show that tokens can acquire value through a mechanism where entrepreneurs generate buyer competition by setting divide-the-money prices, despite lacking traditional equity-like cash flow rights. However, we uncover a fundamental tension: when ventures face ongoing operational costs, they must retain tokens to credibly commit to fair pricing, yet this conflicts with their need to sell tokens to raise development capital. We prove this leads to an impossibility result for simple token structures and demonstrate how observed practices such as vesting schedules, multi-stage offerings, and pre-committed buybacks resolve this tension. Our analysis reveals that while venture returns are independent of token supply growth, initial fundraising is maximized by setting that growth to zero. Beyond traditional ICOs, our model applies to various token-based financing mechanisms including layer-1 protocols, DeFi platforms, and Web3 applications, providing insight into how these mechanisms facilitate coordination among stakeholders in digital ecosystems.
"Cryptocurrency market has been growing fast since its emergence in recent years. Moreover, digital finance has forged the convergence of profit motives with social objectives creating a class of large FinTech companies. In addition, the underlying technology innovation may be applied to a wide range of industries, not limited to financial sector. Yet, few researches have been done to study these phenomena. Hence, it is the task of this book to shed light on the introduction and trends in FinTech, blockchain and token sales. Inclusive FinTech: Blockchain, Cryptocurrency and ICO hopes to dispel the many misconceptions about blockchain and cryptocurrencies (especially bitcoin, Initial Crypto-Token Offering or ICO), as well as the idea that businesses can be sustainable without a social dimension going forward. It is written for those who are looking for a switch from their career to something more meaningful and sustainable, as well as those who want a deeper understanding of where to search for business opportunities. Most important of all, this book seeks to change the mindset of a whole new generation that is familiar with digital economy and yearns for a more just and equitable world."--Publisher's website
Purpose The purpose of this paper is to analyze underpricing in initial coin offerings (ICO). It bridges the gap between findings in initial public offering (IPO) literature and empirical results from ICOs. Design/methodology/approach The sample set consists of 279 ICOs between April 2013 and January 2018. A regression analysis is performed with data from the ICOs. Findings The results show an average level of underpricing of ICOs of 123 percent in the USA and 97 percent in the other countries. The results for the US ICOs are significantly higher than for US IPOs on average and also higher than US IPOs at the beginning of the dot.com bubble. The authors also study the determinants of ICO underpricing. The authors use proxies based on asymmetric information from the IPO literature as well as ICO-related variables. First-day trading volume and a good sentiment on the ICO market go together with more ICO underpricing. Moreover, hot markets make first-day investors to benefit less. Finally, companies that use a large issue size or a pre-ICO (a sale of cryptocurrencies before the ICO) leave less money on the table. Research limitations/implications A first restriction is that the authors focus on ICOs and not on crowdfunding, though there are similarities in that both of them are novel ways to finance projects. A second restriction is that the authors had to decide on the definition of a listing day. Cryptocurrencies are traded on many exchanges, and if the exchange is tailored to the cryptocurrency itself, the data on, e.g., close prices are not necessarily to be trusted. The authors, therefore, decided to use close price data from coinmarketcap.com, which requires a listing on two exchanges. This choice implies that there may have been trades before the listing day itself. A third restriction arises from the relative newness of the ICO phenomenon. The authors gathered data on underpricing from coinmarketcap.com and combined that with project information from icobench.com. However, the data were not simply matched and they required manual adjustments based on several other sources. The authors hope that in due time data on ICOs will be as adequate as data on IPOs and that they become more readily available. It might help if regulators or the crypto community would institute publication requirements. Adherence to such requirements would also reduce the extent of fraud and of asymmetric information, so that solid issuers with good projects might benefit from less underpricing. Practical implications The research may help in reducing underpricing, as the authors find that issuers can reduce it by holding a pre-ICO and by considering larger issue sizes. If they do so, investors will get fewer opportunities to benefit from underpricing. Investors can, nevertheless, also profit from the knowledge generated in this paper. When market sentiment is positive and first-day trading volume is expected to be high, investing in ICOs is likely to give them higher first-day returns. Finally, the authors hope that this paper will serve as a basis for further research into the exciting and dynamic world of cryptocurrencies. Originality/value There is hardly any research on underpricing of ICOs. The paper is interesting for its table with a brief comparison of ICOs and IPOs. It also searches for variables from the asymmetric information theory behind IPOs to be applied in explaining ICOs. It shows high levels of ICO underpricing in comparison to IPOs. It also gives suggestions for issuers of (and investors in) ICOs.

In financial trading, cryptocurrencies like bitcoin use decentralization, traceability, and anonymity features to perform transactional activities. These digital currencies, using the emerging blockchain technologies, are forming the basis of the largest unregulated markets in the world. This creates various regulatory challenges, including the illicit purchase of drugs and weapons, money laundering, and funding terrorist activities. This chapter analyzes various legal and ethical implications, their effects, and various solutions to overcome the inherent issues that are currently faced by the policymakers and regulators. The authors present the result of an analysis of 30 recently published peer-reviewed scientific publications and suggest various mechanisms that can help in the detection and prevention of illegal activities that currently account for a substantial proportion of cryptocurrency trading. They suggest methods and applications that can also be used to identify the dark marketplaces in the future.
The evolution of money has accompanied the development of civilizations and technological innovations, leading to today’s cryptocurrencies. Cryptocurrencies have become a popular mode of payment globally because of their low cost, high-speed transferability and a decentralized tracking network that provides secure transactions and a high degree of anonymity. However, the decentralized system of cryptocurrencies has made global monetary systems more dynamic and therefore more prone to misuse as well as posing a threat to financial stability. Cryptocurrencies are also gaining popularity in Pakistan: its first cryptocurrency, named ‘Pakcoin’, was launched in 2015. The State Bank of Pakistan does not recognize any digital currency, and the Federal Board of Revenue and Federal Investigation Agency have taken legal action against local and internationally traded cryptocurrencies. This article reviews these risks and provides various regulatory solutions so that methods can be developed to improve the management of financial innovations and create a safer environment in which financial innovation can continue. Furthermore, developing countries such as Pakistan can take advantage of distributed ledger technology (used in cryptocurrencies) in applications including: microfinance to help the unbanked, in data identification systems and in land registries to help enforce property rights.
In the past decade, many blockchain and DLT frameworks have flooded the market, but Ethereum is still the favorite of most blockchain lovers. As per a recent report, “Ethereum currently has the most active developer community in the space and has 30 times more developers than the second most active community.” The Ethereum blockchain does have some issues, yet it’s the market leader in its space, and no other framework is anywhere even close to this framework.
Using tick-level bitcoin data from February 2013 through April 2018, we show substantial arbitrage spreads between global bitcoin markets. Spreads follow multiple consistent patterns. Minimum and maximum prices show significant clustering. Spreads increase during the early hours of a day (according to coordinated universal time), when new exchanges enter markets, and following bitcoin heists and hacks. The full year 2017 and the first quarter of 2018 each had exploitable net arbitrage profit opportunities of at least USD380 million that smart money failed to capture. Based on long-term analyses, we also found that bitcoin market inefficiency has increased over time.
Aim/Purpose: This paper explored the factors (enablers and barriers) that affect Bitcoin adoption in South Africa, a Sub-Saharan country with the high potential for Bitcoin adoption. Background: In recent years, Bitcoin has seen a rapid growth as a virtual cryptocurrency throughout the world. Bitcoin is a protocol which allows value to be exchanged over the internet without a central bank or intermediary. Cryptocurrencies such as Bitcoin are technological tools that arguably can contribute to reducing transactions costs. This paper explored the factors that affect Bitcoin adoption in South Africa, a Sub-Saharan country with the high potential for Bitcoin adoption, as little is known about the factors that affect Bitcoin adoption and the barriers to adoption. Methodology: A quantitative questionnaire was distributed to South African virtual communities where Bitcoin is a topic of interest, and 237 quantitative responses were received, along with 212 open-ended comments. Contribution: This research contributes to the body of knowledge in information systems by providing insights into factors that affect Bitcoin adoption in South Africa. It raises awareness of incentives and barriers to Bitcoin adoption at a time when financial literacy is a crucial issue both in South Africa and worldwide. Findings: The results indicate that perceived benefit, attitude towards Bitcoin, subjective norm, and perceived behavioral control directly affected the participants’ intentions to use Bitcoin. Perceived benefit, usefulness, ease of use, and trust-related risk were found to indirectly affect intention to use Bitcoin. Further, it emerges that the barriers to Bitcoin adoption in South Africa consist of the complex nature of Bitcoin and its high degree of volatility. Recommendations for Practitioners: Bitcoin can contribute to reducing transactions costs, but factors that affect adoption and the barriers to adoption should be taken into consideration. These findings can inform systems and software developers to develop applications that make managing Bitcoin keys and transacting using Bitcoin less complex and more intuitive for end users. Recommendation for Researchers: Bitcoin adoption in South Africa is a topic that has not been previously researched. Researchers could research similarities or differences in the various constructs that were used in this research model. Impact on Society: South African Bitcoin users consider it as a universal currency that makes cross-border payments cheaper. A large number of refugees and workers in South Africa make regular payments across borders. Bitcoin could reduce the costs of these transfers. Future Research: Future research could explore Bitcoin (and other cryptocurrencies) adoption in other developing countries. Researchers could look at factors that influence cryptocurrency adoption in general. The factors affecting adoption of other cryptocurrencies can be compared to the results of this study, and similarities and differences can thus be identified.
This article presents a brief overview of the Distributed Ledger Technology, Token Offering and their regulation, if any, in four main jurisdictions, the United States (U.S.), Switzerland, the European Union (EU), and Singapore. It should be noted that is expected to have new developments on the regulatory side, in this and other jurisdictions, of Distributed Ledger Technology and token offerings, Malta, for example, has recently officially stated the creation of the Malta Digital Innovation Authority that will be responsible to regulate and incentivize this industry in Malta and the EU. Distributed Ledger Technology and token offerings are fairly new concepts and are revolutionizing different industries at an incredibly fast pace. The regulators, as well as all other stakeholders, must maintain attention and remain vigilant to any developments in this regard. Conclusively, the Distributed Ledger Technology will, undoubtedly, bring innovative solutions to different industries, especially the financial services industry. As analyzed in the present article, key components previous to launching a token offering, are: define the jurisdiction that will be used for the corporate structure; the categorization of the token; and the applicable regulation accordingly.
The blockchain could be the most consequential development in information technology since the Internet. Created to support the Bitcoin digital currency, the blockchain is actually something deeper: a novel solution to the age-old human problem of trust. Its potential is extraordinary. Yet, this approach may not promote trust at all without effective governance. Wholly divorced from legal enforcement, blockchain-based systems may be counterproductive or even dangerous. And they are less insulated from the law’s reach than it seems. The central question is not how to regulate blockchains but how blockchains regulate. They may supplement, complement, or substitute for legal enforcement. Excessive or premature application of rigid legal obligations will stymie innovation and forego opportunities to leverage technology to achieve public policy objectives. Blockchain developers and legal institutions can work together. Each must recognize the unique affordances of the other system.
This paper presents an introduction to the current state of art of the Blockchain and Smart Contract technologies. Blockchain is a fast-disruptive technology becoming a key instrument in share economy. The Blockchain-based Smart Contract aim to automatically and securely execute the needed responsibilities of a contract without the support of a centralized execution authority. The Smart Contract runs on top of the Blockchain to facilitate, execute and enforce an agreement between un-trusted parties without the interfere of third party to trust it as this Smart Contract is an executable code that runs with rules on the Blockchain. Smart Contracts have some features that serve the goals of social justice and fairness. The paper presents the basic important information about the structures of the Blockchain and Smart Contract technologies and conduct a comparison between the different methodologies used in the Smart Contracts. The issues faced within the Smart Contract technology are surveyed. The four key issues are identified as: codifying, security, privacy and performance issues. We survey case cases of usage of the Blockchain in various business sectors like real estate, voting system and supply chain. The paper aims to assist a developer to grasp the big picture of the Blockchain technology and to further assist in the decision process of suitability of the technology to a specific application area.
Smart contracts, self-executing agreements based on blockchain technology, have the capacity to create trust in what we term no-trust contracting environments. We argue that using them in such environments is the path to unleash the full potential of smart contracts. Compared to the contract enforcement mechanisms characterized by traditional contract law or relational contracts, smart contracts can offer a superior solution for facilitating trade.
Several lawyers and economists have debated whether smart contracts might offer the prospect of cheaper, faster and better transactions. As we discuss below, contract law scholars caution that they neither replicate the relational context essential for the day-to-day practice of contracting nor offer a superior solution to problems addressed by traditional contract law, such as contract validity and legality. We clarify and systematize the current thinking on the legal nature and reliability of smart contracts, and address the concerns of contract law scholars. While doing that, we suggest a step forward in characterizing contracting environments, contract enforcement mechanisms and the trust relationship underlying contracts.
Current shareholder engagement systems face large classical inefficiencies. First, due to the large chains of intermediaries in the current securities models, transaction costs are high and shareholder votes and other information are not always correctly transmitted between shareholders and issuers. Recent cases including DNick Holding and T. Rowe Price show the ‘absurdness’ of the current systems. The Shareholder Rights Directive II addresses these problems and the Implementing Regulation already hints at modern technologies to increase the transparency and verifiability of shareholder engagement. Next, the current shareholder engagement system enables different opportunities for different types of shareholders, creating inequalities and hindering shareholder democracy. The solution to these substantial problems lies in a state-of-the-art technology: in this contribution we argue that blockchain technology can solve these current inefficiencies that shareholders and companies face. Using a permissioned blockchain, information can be stored in a verifiable and immutable way, with a consensus mechanism tailored to its purpose. The large amount of initiatives and prototypes of blockchain proxy voting and trading, including the legislative initiatives that were initiated in the past 2 years, show the merits of using this state-of-the-art technology. The Europe Union should incorporate this technology in its legislation, like the CSD regulation, for remaining technology-proof in this globalized market.

This article offers a normative analysis of key blockchain technology concepts from the perspective of copyright law. Some features of blockchain technologies—scarcity, trust, transparency, decentralized public records and smart contracts—seem to make this technology compatible with the fundamentals of copyright. Authors can publish works on blockchain creating a quasi-immutable record of initial ownership, and encode ‘smart’ contracts to license the use of works. Remuneration may happen on online distribution platforms where the smart contracts reside. In theory, such an automated setup allows for the private ordering of copyright. Blockchain technology, like Digital Rights Management 20 years ago, is thus presented as an opportunity to reduce market friction, and increase both licensing efficiency and the autonomy of creators. Yet, some of the old problems remain. The article examines the differences between new, smart-contract-based private ordering regime and the fundamental components of copyright law, such as exceptions and limitations, the doctrine of exhaustion, restrictions on formalities, the public domain and fair remuneration.
There is an immense need of a proof of delivery (PoD) of today's digital media and content, especially those that are subject to payment. Current PoD systems are mostly centralized and heavily dependent on a trusted third party (TTP) especially for payment. Such existing PoD systems often lack security, transparency, and visibility, and are not highly credible, as the TTP can be subject to failure, manipulation, corruption, compromise, and hacking. In this paper, we propose a decentralized PoD solution for PoD of digital assets. Our solution leverages key features of blockchain and Ethereum smart contracts to provide immutable and tamper-proof logs, accountability, and traceability. Ethereum smart contracts are used to orchestrate and govern all interactions and transactions including automatic payments in Ether cryptocurrency between customers, digital-content provider, and the file server hosting the digital content. All entities are incentivized to act honestly, and our solution has a mechanism to handle dispute if arisen among participants. The solution has an off-chain secure download phase involving the file server and customers. Moreover, our solution leverages the benefits of interplanetary file system to store the agreed upon terms and conditions between the smart contract actors. A security analysis of our proposed system has been provided. The full code of the smart contract has been publicly made available on Github.

Blockchain-based smart contracts are emerging as a disruptive force that may change the way financial statement audits are performed and delivered. With their potential ability to autonomously execute audit procedures on behalf of the auditor and disclose the results of these audit procedures, blockchain-based smart contracts have the potential to improve audit quality and meet the information demands of various vested parties for more timely and transparent audit reporting. This paper proposes the application of smart contracts to auditing as an enabler for improved audit data analytics and close to real-time audit reporting.
A smart contract is hard to patch for bugs once it is deployed, irrespective of the money it holds. A recent bug caused losses worth around $50 million of cryptocurrency. We present ZEUS-a framework to verify the correctness and validate the fairness of smart contracts. We consider correctness as adherence to safe programming practices, while fairness is adherence to agreed upon higher-level business logic. ZEUS leverages both abstract interpretation and symbolic model checking, along with the power of constrained horn clauses to quickly verify contracts for safety. We have built a prototype of ZEUS for Ethereum and Fabric blockchain platforms, and evaluated it with over 22.4K smart contracts. Our evaluation indicates that about 94.6% of contracts (containing cryptocurrency worth more than $0.5 billion) are vulnerable. ZEUS is sound with zero false negatives and has a low false positive rate, with an order of magnitude improvement in analysis time as compared to prior art.
The question of regulation in the domain of cryptocurrencies has been tackled in various ways, exhibiting therein a desire to strike a balance between fostering innovation and promoting oversight. This chapter examines the case of BitLicense, issued by the New York Department of Financial Services (DFS), with the aim of contextualizing the relative merits of regulatory and oversight initiatives in the domain of cryptocurrencies. This includes an examination of the impact and critiques regarding BitLicense since its promulgation, along with the use of perspectives from public value theory (PVT) to contextualize the value creation efforts of the DFS using BitLicense as a regulatory instrument. The findings of the chapter suggest that contrasting views exist on the value creation of cryptocurrency regulations, and this is reflected both in a PVT approach as well as the evolving praxis of virtual currency regulatory and oversight efforts.
Drawing on an empirical study of cryptocurrency white papers, this paper proposes an actor-based taxonomy of cryptocurrency blockchains. First, it describes the evolution of blockchain architecture with reference to the economic services that blockchains supply. Second, it discusses the socio-technical platform of blockchains as proposed in cryptocurrency white papers. Third, it analyses the socio-economic consequences of these technically diverse blockchain platforms, by proposing a taxonomy of their digital architectures in reference to two groups of actors that maintain blockchain infrastructure: transactioners and accountants. Defining cryptocurrency as data money, and locating cryptocurrency ownership as the possession of an exclusive right to move data privately in a public or private space, the paper describes a blockchain as a digital actor-network platform that makes it possible to define and distribute these data transfer rights.

In this paper, we present a method for predicting changes in Bitcoin and Ethereum prices utilizing Twitter data and Google Trends data. Bitcoin and Ethereum, the two largest cryptocurrencies in terms of market capitalization represent over \$160 billion dollars in combined value. However, both Bitcoin and Ethereum have experienced significant price swings on both daily and long term valuations. Twitter is increasingly used as a news source influencing purchase decisions by informing users of the currency and its increasing popularity. As a result, quickly understanding the impact of tweets on price direction can provide a purchasing and selling advantage to a cryptocurrency user or a trader. By analyzing tweets, we found that tweet volume, rather than tweet sentiment (which is invariably overall positive regardless of price direction), is a predictor of price direction. By utilizing a linear model that takes as input tweets and Google Trends data, we were able to accurately predict the direction of price changes. By utilizing this model, a person is able to make better informed purchase and selling decisions related to Bitcoin and Ethereum.
