Abstract: With the increasing digitalization of health data, patients need to make informed decisions about the online sharing of their protected health information. This necessitates a robust technical infrastructure that enables patients to self-manage consent and the trusted exchange of this information across sharing entities. Unfortu nately, current health information exchange systems in the U.S. are limited in both these regards. While there is recent work on digital patient consent management, there is limited work that provides effective solutions for patient self-management of consent. Further, interoperability issues in the way health information exchanges are currently architected and differences in regulations across localities exacerbate the challenges of consent man agement. In this research, we survey potential patients' willingness to self-manage healthcare-related consent. Having established the desire for consent self-management, we propose a solution that enables the seamless sharing of patient consent across different healthcare providers and health information exchanges. Specifically, we use a rigorous design science approach to create a blockchain-based, self-managed patient consent system and we evaluate the design through an instantiated prototype. The results of our study should be useful to researchers in healthcare information management as well as to practitioners designing consent management systems. Our research contributes to design science research with an innovative, rigorously evaluated, design principles-based artifact that addresses a critical problem of sharing protected health information.

A Taxonomy of Violations in Digital Asset Markets

Abstract: Numerous frauds, market manipulations and other violations have recently shaken investor confidence in digital asset markets and digital assets themselves. Yet, investor confidence and market integrity are key requirements for the continued success of crypto and other digital assets. In order to facilitate the integrity of digital asset markets and avoid integrity incidents in the future, a systematic overview of violations and their main characteristics is needed to develop appropriate countermeasures. Therefore, we develop a taxonomy of violations in digital asset markets and evaluate the taxonomy based on real-world cases. Our results show that many types of market manipulation in traditional financial markets can also be observed in digital asset markets. However, there are new and additional violations in digital asset markets. We also find that many violations depend on specific capabilities of the violator, certain trading conditions, and asset-specific characteristics.

Patient Consent for Health Information Exchange: Blockchain-driven Innovation

Abstract: Health information exchange (HIE) is vital to improving care delivery and outcomes, and patient consent is an important component of HIE. Existing consent processes that involve completing forms at a provider, along with poor interoperability between HIEs, give patients limited control of their consent management. We developed and deployed a survey to assess how people perceive the value of HIE, the importance of controlling access to their protected health information (PHI), and how they would prefer to manage consent for the exchange of their PHI. Given the option, 70% of the participants would prefer to use a consent application (app) to manage their consent. Based on the current U.S. HIE environment, we argue that the most viable architecture for implementing an HIE consent app would be a permissioned blockchain. We describe and illustrate a consent management app prototype that is blockchain-based as an effective alternative to current HIE consent practices.

Abstract: Enabled by blockchain technology, token sales (TSs) have emerged as a new type of crowdfunding. Startups raise money through the sale of crypto tokens, which grant rights on a future application. In contrast to traditional forms of crowdfunding, issuers and buyers transact directly in TSs using blockchain technology. Owing to the absence of trust-creating intermediaries and control instances, a socalled 'trust frontier' emerges. Thus, the role and formation of trust in the context of TSs is an interesting field of study. Through an explorative qualitative study, we identify and analyse trustestablishing technological artefacts in TSs. We find that while some factors equally create trust in traditional crowdfunding and in TSs, TSs give rise to new trust-building technological artefacts (e.g., code hosting services, crypto exchanges) or increase the importance of existing artefacts (e.g., social media platforms). Our study contributes to research on blockchain and crowdfunding and provides guidance for issuers, buyers, and regulators in understanding the mechanisms of trust formation in the context of TSs.2 Contrarily, TSs cut out these traditional intermediaries. The underlying blockchain and its selfexecuting software, so-called smart contracts, serve as the "trust machine" (The Economist, 2015), disabling double spending and record manipulation through a consensus mechanism and cryptography. While TSs offer various advantages to issuers and buyers, buyers face high levels of risk due to the decentralized nature and technologic novelty underlying TSs in addition to risks known from established types of crowdfunding (Bannerman, 2013;Werbach, 2018). Risks related to technological vulnerabilities, buyers' impeded due diligence abilities, and fraud have given reason for distrust in this new form of peer-to-peer venture funding model (Amsden and Schweizer, 2018;Kaal and Dell'Erba, 2017). In extreme cases, so-called exit scams have occurred, wherein the collected funds were stolen and the founders "disappeared" (Elendner et al, 2016;Kaal and Dell'Erba, 2017). In this case, the blockchain features of pseudonymity and decentralization turn into an escape route for scammers. Thus, studying how trust is established between market participants in such an environment is of special interest. Building upon extant research, we suggest that technological artefacts arise to mediate between the interacting parties and help bridge the trust frontier in TSs. Given, the novelty of the TS phenomenon, our study objective is the identification of the technological artefacts used for creating trust in TS processes. We further discuss in which ways they help overcome trust issues in TSs. This paper is exploratory in nature as research on the emergent phenomenon of creating trust in blockchain-based crowdfunding is embryonic. In the space of time between March 2018 and November 2019, we conducted 22 interviews with TS consultants, TS issuers, and TS buyers to investigate by which technological artefacts (Iivary, 2007) trust through ability, integrity, and benevolence (Mayer et al, 1995) is created in startups that seek to raise capital by blockchain-based crowdfunding. We find that beyond trust mechanisms known from traditional, intermediary-based crowdfunding, TSs bring about new trust-building technological artefacts (e.g., code hosting services) and sustainably increase the importance of existing mechanisms (e.g., social media platforms).Our study contributes to research on information technology (IT) affordances in crowdfunding (Choy et al, 2016) as well as to the emerging stream of information systems (IS) research on blockchain technology (Avital et al, 2016;Beck et al, 2017;Nagel et al, 2019) and TSs (Catalini and Gans, 2018;Conley, 2017). The long-term impact that TSs will have in the field of entrepreneurial finance is still open. Regulators are currently challenged by the question of how and to which extent to seize control over TSs for buyer protection purposes (Zetzsche et al, 2018). In this context, our research topic is of especial relevance, disclosing mechanisms that are central to the issuer-buyer relationship. Our findings help startups, buyers, regulators, and other stakeholders understand the IT-afforded mechanisms of trust formation in the context of TSs (Venegas, 2017). They are further relevant for other markets that face disintermediation due to blockchain technology, such as sharing economy (Hawlitschek et al, 2018;Pazaitis et al, 2017). The remainder of this paper is structured as follows. First, we introduce TSs as novel types of crowdfunding. We then review literature on the role of trust in crowdfunding to develop a theoretical understanding of the challenges that may arise in the absence of an intermediary. The role of technological artefacts in trust formation completes the theoretical foundation. We then explain our methodology and present our findings along the identified technological artefacts. Last, we refer to the study's contributions and implications for researchers and practitioners.
