A patient suffering from a severe illness that is entering its terminal stage is forced to develop a coping process. Of all the coping patterns, the religious one stands out as being a psychological resource available to all patients regardless of culture, learning, and any age. Religious coping interacts with other values or practices of society, for example the model of a society that takes care of it's elder members among family or in an institutionalized environment or the way the (...) health system offers or not psychological support for a terminally ill patient. Health care providers should have at least some psychological coping patterns training because not all patterns of religious coping are equally effective, and some have been described as increasing the level of stress or producing other negative psychological effects on the patient. This article aims to review the complex models of religious coping that are unanimously accepted in psychooncology, arguments in favor of religious coping, the types of patients that use this model, ethical dilemmas that could be reinterpreted using religious arguments. Finally, we will also discuss the need of Romanian patients to embrace a religious coping in case of an incurable illness, and also the support that they can receive from both curative and palliative health care providers.  .

With DLT’s success in driving the development of cryptocurrency (such as Bitcoin), the technology bridged to a myriad of knowledge-based applications, most notably in the areas of commerce, industry and government . In the language of technology sector insiders, these areas were ‘disrupted’ by Blockchain. Some higher education analysts, technology industry insiders and futurists have claimed that Blockchain technology will inevitably disrupt higher education in a similarly dramatic fashion. The aim of this commentary is to introduce a healthy (...) dose of realism into the hype-filled atmosphere of the Blockchain-for-higher-education narrative. A postdigital approach is taken because it treats digital and non-digital technologies as having equal material and cultural standing as candidates to transform higher education. (shrink)

This paper argues that many so-called digital technologies can be construed as notational technologies, explored through the example of Monegraph, an art and digital asset management platform built on top of the blockchain system originally developed for the cryptocurrency bitcoin. As the paper characterizes it, a notational technology is the performance of syntactic notation within a field of reference, a technologized version of what Nelson Goodman called a “notational system.” Notational technologies produce abstracted entities through positive and reliable, or (...) constitutive, tests of socially acceptable meaning. Accordingly, this account deviates from typical narratives of blockchains, instead demonstrating that blockchain technologies are effective at managing digital assets because they produce abstracted identities through the performance of notation. Since notational technologies rely on configurations of socially acceptable meaning, this paper also provides a philosophical account of how blockchain technologies are socially embedded. (shrink)

Recent advances in medical and information technologies, the availability of new types of medical data, the requirement of increasing numbers of study participants, as well as difficulties in recruitment and retention, all present serious problems for traditional models of specific and informed consent to medical research. However, these advances also enable novel ways to securely share and analyse data. This paper introduces one of these advances—blockchain technologies—and argues that they can be used to share medical data in a secure (...) and auditable fashion. In addition, some aspects of consent and data collection, as well as data access management and analysis, can be automated using blockchain-based smart contracts. This paper demonstrates how blockchain technologies can be used to further all three of the bioethical principles underlying consent requirements: the autonomy of patients, by giving them much greater control over their data; beneficence, by greatly facilitating medical research efficiency and by reducing biases and opportunities for errors; and justice, by enabling patients with rare or under-researched conditions to pseudonymously aggregate their data for analysis. Finally, we coin and describe the novel concept of prosent, by which we mean the blockchain-enabled ability of all stakeholders in the research process to pseudonymously and proactively consent to data release or exchange under specific conditions, such as trial completion.

This paper argues that the practical implementation of blockchain technology can be considered an institution of property similar to legal institutions. Invoking Penner's theory of property and Hegel's system of property rights, and using the example of bitcoin, it is possible to demonstrate that blockchain effectively implements all necessary and sufficient criteria for property without reliance on legal means. Blockchains eliminate the need for a third-party authority to enforce exclusion rights, and provide a system of universal access to (...) knowledge and discoverability about the property rights of all participants and how the system functions. The implications of these findings are that traditional property relations in society could be replaced by or supplemented with blockchain models, and implemented in new domains. (shrink)

The central theme of this paper is that the development of a technology that is predicted to have a major impact on the way we transact with each other should be a matter where the needs of society at large are taken into account. Where the technology is one that emerges from the domain of the Internet, inclusivity becomes even more acute in order to avoid widening the already existing gap in reaping the “digital dividend.” With blockchain, the obligation (...) could even be seen as a moral one, as blockchain is said to have the potential to negate the scope for the abuse of trust by states and institutions. This could be a game changer in areas such as public procurement and the conduct of elections where abuse can lead to the denial of essential resources and a concomitant loss of life, or to conflict and mass killings. Blockchain presents an opportunity for the Internet development community to claim a degree of recognition in the human rights realm by aiding civil intervention in areas where military intervention has been deemed inappropriate.

Participation in research is supposed to be voluntary and informed. Yet it is difficult to ensure people are adequately informed about the potential uses of their biological materials when they donate samples for future research. We propose a novel consent framework which we call “demonstrated consent” that leverages blockchain technology and generative AI to address this problem. In a demonstrated consent model, each donated sample is associated with a unique non-fungible token (NFT) on a blockchain, which records in (...) its metadata information about the planned and past uses of the sample in research, and is updated with each use of the sample. This information is accessible to a large language model (LLM) customized to present this information in an understandable and interactive manner. Thus, our model uses blockchain and generative AI technologies to track, make available, and explain information regarding planned and past uses of donated samples. (shrink)

One of the early, non-financial uses of blockchain technologies around which several startups have developed was to help manage, monetize, and make the sharing of genomic data more private. Because deidentified genomic data are excluded from HIPAA and many other regulatory contexts worldwide—and is already a widely traded commodity for science valued in the hundreds of millions over the past decade—genomic blockchains proved a promising entry point for using the benefits of blockchains for dissemination and remuneration of data. Several (...) models have been tried, and most have touted their abilities to make users the “owners” of the genomic data in ways in which current models fail. This paper will explore the various existing and potential models for genomic blockchains, review some shortcomings and unmet needs, and explain why no technical solution alone will fulfill the promise of genomic data ownership without regulation.

The rise of blockchain as a techno-solution in the development sector underscores the critical imbalances of data power under ‘computational capitalism’. This article will consider the political economy of techno-solutionist and blockchain discourses in the developing world, using as its object of study blockchain projects in Pacific Island nations. Backed by US State Department soft power initiatives such as Tech Camp, these projects inculcate tech-driven notions of economic and political development, or ICT4D, while opening up new terrains (...) for data accumulation and platform control. Blockchain developers in search of proof of concept have found the development sector a fecund space for tech experimentation as they leverage a desire for tech-development and exploit regulatory weakness. The material implications of blockchain projects and discourse have been to create governance solutions which bypass the developing world state as a largely corrupting intermediary. In the Pacific, this has meant blockchain supply-chain management systems, proprietary financial innovation in humanitarian relief and an Asian Development Bank project to manage indigenous Fijian lands exclusively on the blockchain. In all these instances, discourses of solutionism, innovation and data empowerment have been deployed in aid of blockchain cartographies of control. (shrink)

There is no question about the innovation force and the economic potential of blockchain technology. As the basis for new currencies, financial services, and smart contracts, blockchain technology can be seen as the fifth disruptive computing paradigm, after mainframes, personal computers, the Internet, and mobile devices. However, there are questions about its ethical implications, which have the potential to also impact the economic success of blockchain technology. This article aims to provide ethical guidance on blockchain technology. (...) In order to reach this goal, the focus of the ethical analysis will first concentrate on the unique characteristics of blockchain technology compared to other technology-based innovations. The unique nucleus of blockchain technology can be defined as a move from the trust in people to a trust in math, as a move from an internet of information to an internet of value, or—as I would propose—a shift from an intermediated network to an immediate network. Second, the ethical opportunities (e.g., transparency, participation, global access to services) and risks (e.g., ecological impact, lack of legal monitoring and enforcement) associated with this unique nucleus of blockchain technology will be discussed. Third, an outlook on possible concrete solutions will be provided. (shrink)

A sustainable supply chain management strategy reduces risks and meets environmental, economic and social objectives by integrating environmental and financial practices. In an ever-changing environment, supply chains have become vulnerable at many levels. In a global supply chain, carefully tracing a product is of great importance to avoid future problems. This paper describes a self-updating smart contract, which includes data validation, for tracing global supply chains using blockchains. Our proposal uses a machine learning model to detect anomalies on traceable data, (...) which helps supply chain operators detect anomalous behavior at any point in the chain in real time. Hyperledger Caliper has been used to evaluate our proposal, and obtained a combined average throughput of 184 transactions per second and an average latency of 0.41 seconds, ensuring that our proposal does not negatively impact supply chain processes while improving supply chain management through data anomaly detection.

In discussions on the ethics of genome collections and biobanks, the main worry about whether we are permitted to collect and use individuals’ genomic and genetic data is the potential for the violation of individuals’ right to informational privacy. Yet, if we do not permit these endeavors, we risk giving up on the future benefits of biomedical research. In this paper, I describe a private venture in blockchain genomics that seeks to provide an apt solution to concerns about potential (...) privacy violations in genome collections and biobanks. I then provide some reasons to doubt the kind of solution to the dilemma that such start-ups propose. I argue that the sort of autonomy that grounds the value of the right to informational privacy cannot be secured with blockchain technology alone. So, blockchain genomics ventures are insufficient to establish the permissibility of genome collections and biobanks. I then discuss an additional ethical challenge to genomic biobanks. This challenge takes the form of doubting that future benefits that result from biomedical research dependent on genomic databases will outweigh the costs. Despite criticisms of genomic research, I claim that it is reasonable to think that future net benefits will be gained from research on such databases. Therefore, I conclude that there remains a dilemma in the ethics of genomic biobanks. (shrink)

Logistics services involve a wide range of transport operations between distributors and clients. Currently, the large number of intermediaries are a challenge for this sector, as it makes all the processes more complicated. To face that problem, we propose a system that uses smart contracts to remove intermediaries and speed up logistics activities. Our new model combines smart contracts and a multi-agent system in a single platform to improve the current logistics system by increasing organization, security and getting rid of (...) several human intermediaries to automate its processes, making distribution times significantly faster. Also, with this kind of approach, it is possible to apply penalties to parties that do not comply with the terms of using this platform. (shrink)

Randomization is an integral part of well-designed statistical trials, and is also a required procedure in legal systems. Implementation of honest, unbiased, understandable, secure, traceable, auditable and collusion resistant randomization procedures is a mater of great legal, social and political importance. Given the juridical and social importance of randomization, it is important to develop procedures in full compliance with the following desiderata: (a) Statistical soundness and computational efficiency; (b) Procedural, cryptographical and computational security; (c) Complete auditability and traceability; (d) Any (...) attempt by participating parties or coalitions to spuriously influence the procedure should be either unsuccessful or be detected; (e) Open-source programming; (f) Multiple hardware platform and operating system implementation; (g) User friendliness and transparency; (h) Flexibility and adaptability for the needs and requirements of multiple application areas (like, for example, clinical trials, selection of jury or judges in legal proceedings, and draft lotteries). This paper presents a simple and easy to implement randomization protocol that assures, in a formal mathematical setting, full compliance to the aforementioned desiderata for randomization procedures.

This article introduces the symposium “Toward a Philosophy of Blockchain,” which provides a philosophical contemplation of blockchain technology, the digital ledger software underlying cryptocurrencies such as bitcoin, for the secure transfer of money, assets, and information via the Internet without needing a third-party intermediary. The symposium offers philosophical scholarship on a new topic, blockchain technology, from a variety of perspectives. The philosophical themes discussed include mathematical models of reality, signification, and the sociopolitical institutions that structure human life (...) and interaction. The symposium also investigates the metaphilosophical theme of how to create a philosophy of anything, specifically a new topic such as blockchain technology. Repeated themes are identified, in all areas of philosophical inquiry, and conceptual resources are elaborated to contribute to a philosophical understanding of blockchain technology. Thus, philosophy as a metaphilosophical approach is shown to be able to provide an understanding of the conceptual, theoretical, and foundational dimensions of novelty and emergence in the world, with a particular focus on blockchain technology.

The paper focuses on the philosophical challenges of governance over trustless ledgers, namely Bitcoin Layer 2 solutions in El Salvador. Blockchain adoption in El Salvador is an example of policy based on a ‘frontier epistemology’ (Nickles 2009 ), creating a situation where “facts are uncertain, values are in dispute, stakes are high, and decisions are urgent” (Funtowicz and Ravetz 1993 ). Trustless ledgers play a role of such ‘frontiers’ of knowledge and governance that support a variety of technocratic, heuristic, (...) and experimental policy approaches. They challenge the traditional knowledge frameworks and governance processes responsible for attempts to embed (align) predetermined ideologies (values and stakes) into the technology over standards. Instead, as amalgams of social, political, legal, and economic interventions, ledgers function simultaneously as a contract, a monetary system, a political value commitment, and a governance structure. By integrating facts, values, and stakes into algorithms, they define the frontiers of epistemology and governance in two opposing ways. On the one hand, trustless ledgers embody Augustine’s Civitas Dei (the City of God) as a new design (novum consilium) that promises a future world (futurum saeculum) (Augustine 1968 ). With a promise of a system, where everyone is ‘free’ to not being able to ‘sin’ (non posse peccare - delet the res non peccare), social agency is reduced to a code of a trustless infrastructure. On the other hand, ledgers support experimental (Sabel and Zeitlin 2012 ) and heuristic policymaking (Nickles 2009 ) that saves social agency and cuts ‘through traditional discovery/justification and descriptive/ normative distinctions’ (Nickles 2009 ). The distributed ledgers as governance experiments then redefine Civitas Terrena’s governance as a challenge of ‘heuristic appraisal’ (Nickles 2009 ), ‘directly deliberative polyarchy’ (Cohen and Sabel 1997 ), and ‘experimentalist governance’ (Sabel and Zeitlin 2012 ). To elaborate on the blockchain governance experiments, we will use two Bitcoin initiatives in El Salvador (Bitcoin City and Bitcoin Beach) and discuss them in the context of a broader adoption of blockchain in South America.

This paper explores the potential of blockchain technology in revolutionizing intellectual property (IP) protection and its implications for sustainable development goals, particularly those related to peace, justice, and strong institutions. By providing a transparent and immutable ledger for tracking IP ownership, blockchain offers a secure platform to combat fraud and misrepresentation in IP transactions. Additionally, smart contracts can automate IP enforcement, further enhancing protection measures. Beyond IP protection, blockchain fosters transparency in copyright ownership and transactions, facilitating fair (...) compensation for creators and discouraging piracy. However, challenges such as accessibility and regulatory hurdles remain. Despite these limitations, integrating blockchain in IP protection offers transformative opportunities to establish equitable systems, enhance trust, and streamline processes. Collaboration and standardized frameworks are essential for maximizing blockchain's potential in IP protection and advancing sustainable development goals. (shrink)

The following lines aim at two goals: firstly, connecting the three blind spots that Katrin Becker's article has identified in the analysis of society promoted by advocates of blockchain technology; secondly, reflecting on the possible hybridization between classical and digital forms of legal procedures. What we are witnessing is a transfer of legality from a spatial and linguistic order to a non-spatial, non-linguistic one which is based on out-of-space lines of written code. The interpretation of what space means for (...) justice becomes therefore a crucial social stake in the possible hybridization of classical and digital procedures. (shrink)

Purpose The purpose of this paper is to understand the dark side of blockchain technology (BCT) adoption in small and mid-size enterprises. The focus of the authors is to decode the intricate relationship among the selected variables missing in the existing literature. Design/methodology/approach A focused group approach is initiated by the authors to identify the barriers. Total interpretive structural modeling, Matrice d'impacts croisés multiplication appliquée á un classment, that is, matrix multiplication applied to classification and decision-making trial and evaluation (...) laboratory are used to analyze the complex relationships among identified barriers. Findings This study finds that implementation of BCT reduces maintenance cost by withdrawing manual effort, as BCT has better capability to quantify the internal status of the system (observability characteristic). The observability characteristic of BCT provides high compatibility to the system. This study also finds that the compatibility of BCT with the organization reduces implementation cost and facilitates project management. The findings of this study recommend analyzing maintenance cost and compatibility of BCT before implementing it. Small and mid-size enterprises can select complex BCT depending on the sophistication level of IT usage and IT project management capabilities. Research limitations/implications This study comes with various limitations, where the model developed by the authors may not be conclusive, as it is based exclusively on expert opinion. The samples collected may not help in validating the model statistically. Though the model has its limitations, it can still be considered as a nascent initiative for further investigation using structural equation modeling. Originality/value The outcomes of the theoretical and managerial contributions of the study can be categorized into three levels. This study can be used both by the industrialists and researchers to understand the barriers and the recovery methods thereafter. Suggestions that serve as future directives are also discussed by the authors. (shrink)

Decentralised ledgers are gaining momentum following the interest of industries and people in smart contracts. Major attention is paid to blockchain applications intended for trading assets that exploit digital cryptographic certificates called tokens. Particularly relevant tokens are the non-fungible tokens (NFTs), namely, unique and non-replicable tokens used to represent the cryptographic counterpart of assets ranging from pieces of art through to licenses and certifications. A relevant consequence of the hard-coded nature of blockchains is the hardness of probing, in particular (...) when advanced searchers involving the capabilities of the smart contracts or the assets digitised by NFTs are required. For this purpose, a formal representation for the operational semantics of smart contracts and of tokens has become particularly urgent, especially in economy and finance, where blockchains become increasingly relevant. Hence, we feel the need to tailor Semantic Web technologies to achieve that semantic representation at least for NFTS. This article reports on an ontology that leverages the Ontology for Agents, Systems, and Integration of Services (“OASIS”) towards the semantic representation of smart contracts responsible for managing ERC721-compliant NFTs and running on the Ethereum blockchain. Called Ether-OASIS, the proposed ontology adopts OASIS and tailors its behaviouristic approach to the Ethereum blockchain by conceiving smart contracts as agents running on the blockchain and, consequently, smart contract interactions as agent commitments. Smart contracts are represented in terms of their actions, purposes and tokens that they manage, thus realising a blockchain that is more usable both by users and automated applications. The ontology is evaluated using standard ontological metrics and applied on a case study concerning the minting and transferring of NFTs that digitise batches of wheat. (shrink)

This paper looks at the development of blockchain technologies that promise to bring new tools for the management of private data, providing enhanced security and privacy to individuals. Particular interest present solutions aimed at reorganizing data flows in the Internet of Things architectures, enabling the secure and decentralized exchange of data between network participants. However, as this paper argues, the promised benefits are counterbalanced by a significant shift towards the propertization of private data, underlying these proposals. Considering the unique (...) capacity of blockchain technology applications to imitate and even replace traditional institutions, this aspect may present certain challenges, both of technical and ethical character. In order to highlight these challenges and associated concerns, this paper identifies the underlying techno-economic factors and normative assumptions defining the development of these solutions amounting to technologically enabled propertization. It is argued that without careful consideration of a wider impact, such blockchain applications could have effects opposite to the intended ones, thus contributing to the erosion of privacy for IoT users.

Definition of the problem Biomedical research based on big data offers immense benefits. Large multisite research that integrates large amounts of personal health data, especially genomic and genetic data, might contribute to a more personalized medicine. This type of research requires the transfer and storage of highly sensitive data, which raises the question of how to protect data subjects against data harm, such as privacy breach, disempowerment, disenfranchisement, and exploitation. As a result, there is a trade-off between reaping the benefits (...) of big-data-based biomedical research and protecting data subjects’ right to informational privacy. Arguments Blockchain technologies are often discussed as a technical fix for the abovementioned trade-off due to their specific features, namely data provenance, decentralization, immutability, and access and governance system. However, implementing blockchain technologies in biomedical research also raises questions regarding consent, legal frameworks, and workflow integration. Hence, accompanying measures, which I call enablers, are necessary to unleash the potential of blockchain technologies. These enablers are innovative models of consent, data ownership models, and regulatory models. Conclusion Blockchain technologies as a technical fix alone is insufficient to resolve the aforementioned trade-off. Combining this technical fix with the enablers outlined above might be the best way to perform biomedical research based on big data and at the same time protect the informational privacy of data subjects.

An intelligent climate and watering agriculture system is presented that is controlled with Android application for smart water consumption considering small and medium ruler agricultural fields. Data privacy and security as a big challenge in current Internet of Things (IoT) applications, as with the increase in number of connecting devices, these devices are now more vulnerable to security threats. An intelligent fuzzy logic and blockchain technology is implemented for timely analysis and securing the network. The proposed design consists of (...) various sensors that collect real-time data from environment and field such as temperature, soil moisture, light intensity, and humidity. The sensed field information is stored in IoT cloud platform, and after the analysis of entries, watering is scheduled by implementing the intelligent fuzzy logic and blockchain. The intelligent fuzzy logic based on different set of rules for making smart decisions to meet the watering requirements of plant and blockchain technology provides necessary security to the IoT-enabled system. The implementation of blockchain technology allows access only to the trusted devices and manages the network. From the experimentation, it is observed that the proposed system is highly scalable and secure. Multiple users at the same time can monitor and interact with the system remotely by using the proposed intelligent agricultural system. The decisions are taken by applying intelligent fuzzy logic based on input variables, and an alert is transmitted about watering requirements of a field to the user. The proposed system is capable of notifying users for turning water motor on and off. The experimental outcomes of the proposed system also reveal that it is an efficient and highly secure application, which is capable of handling the process of watering the plants. (shrink)

Counterfeiting is common in many industries. For the authenticity of online channel products and to combat counterfeiting, many companies have begun to use blockchain technology to trace product information. This paper investigates a dual-channel supply chain consisting of one manufacturer and one retailer, in which the manufacturer sells its standard products through the retailer and adopts blockchain technology to launch the online channel to sell the traceable products. A Stackelberg game is developed to depict the pricing decision and (...) channel strategy choice for the manufacturer. It shows that both the manufacturer and the retailer can benefit from blockchain adoption. And the longer it takes for product traceability, the lower the price of online traceable products. It is beneficial for the manufacturer when consumers in the market are less concerned about information transparency. For consumer sensitivity, as consumers’ acceptance of direct sales channels increases, the selling prices of online traceable products have risen. Furthermore, as the traceability time-sensitivity coefficient increases, the sales price of the traceable products decreases, and the retail price of offline standard products rises. The conclusion of this paper has a certain guiding role for the dominant manufacturers in choosing whether to apply blockchain technology to improve the demand for traceable products. (shrink)

This paper proposes a novel way to understand trust in blockchain technology by analogy with trust placed in institutions. In support of the analysis, a detailed investigation of institutional trust is provided, which is then used as the basis for understanding the nature and ethical limits of blockchain trust. Two interrelated arguments are presented. First, given blockchains’ capacity for being institution-like entities by inviting expectations similar to those invited by traditional institutions, blockchain trust is argued to be (...) best conceptualized as a specialized form of trust in institutions. Keeping only the core functionality and certain normative ideas of institutions, this technology broadens our understanding of trust by removing the need for third parties while retaining the value of trust for the trustor. Second, the paper argues that blockchains’ decentralized nature and the implications and effects of this decentralization on trust issues are double-edged. With the erasure of central points, the systems simultaneously crowd out the pivotal role played by traditional institutions and a cadre of representatives in meeting their assigned obligations and securing the functional systems’ trustworthy performances. As such, blockchain is positioned as a technology containing both disruptive features that can be embedded with meaningful normative values and inherent ethical limits that pose a direct challenge to the actual trustworthiness of blockchain implementations. Such limits are proposed to be ameliorated by facilitating a shift of responsibility to the groups of people directly associated with the engendering of trust in the blockchain context. (shrink)

A blockchain can be considered a technological phenomenon that is made up of different interconnected and autonomous systems. Such systems are referred to here as cyber-physical systems: complex interconnections of cyber and physical components. When cyber-physical systems are interconnected, a new whole consisting of a system of systems is created by the autonomous systems and their intercommunication and interaction. In a blockchain, individual systems can independently make decisions on joint information transactions. The decision-making procedures needed for this are (...) executed based on fault-tolerant communication and voting and consensus procedures, while the results of these decision-making procedures are stored in distributed ledgers. Due to the intercommunication, interaction, and independent decision making by autonomous systems, the new whole of a blockchain is a complex entity. Complexity science rather than the usual reductionist scientific approach can help us better understand the behaviour of the new and continuously developing whole of a blockchain as a technological phenomenon.

Given a countable model of set theory, we study the structure of its generic multiverse, the collection of its forcing extensions and ground models, ordered by inclusion. Mostowski showed that any finite poset embeds into the generic multiverse while preserving the nonexistence of upper bounds. We obtain several improvements of his result, using what we call the blockchain construction to build generic objects with varying degrees of mutual genericity. The method accommodates certain infinite posets, and we can realize these (...) embeddings via a wide variety of forcing notions, while providing control over lower bounds as well. We also give a generalization to class forcing in the context of second-order set theory, and exhibit some further structure in the generic multiverse, such as the existence of exact pairs. (shrink)

Few recent developments in information technology have been as hyped as blockchain, the first implementation of which was the cryptocurrency Bitcoin. Such hype furnishes ample reason to be skeptical about the promise of blockchain implementations, but I contend that there’s something to the hype. In particular, I think that certain blockchain implementations, in the right material, social, and political conditions, constitute excellent bases for common knowledge. As a case study, I focus on trust in election outcomes, where (...) the ledger records not financial transactions but vote tallies. I argue that blockchain implementations could foster warranted trust in vote tallies and thereby trust in the democratic process. Finally, I argue that if the promise of blockchain implementations as democratic infrastructure is to be realized, then democracies first need to ensure that these material, social, and political conditions obtain.

Self-sovereign identity solutions implemented on the basis of blockchain technology are seen as alternatives to existing digital identification systems, or even as a foundation of standards for the new global infrastructures for identity management systems. It is argued that ‘self-sovereignty' in this context can be understood as the concept of individual control over identity relevant private data, capacity to choose where such data is stored, and the ability to provide it to those who need to validate it. It is (...) also argued that while it might be appealing to operationalise the concept of ‘self-sovereignty’ in a narrow technical sense, depreciation of moral semantics obscures key challenges and long-term repercussions. Closer attention to the normative substance of the ‘sovereignty’ concept helps to highlight a range of ethical issues pertaining to the changing nature of human identity in the context of ubiquitous private data collection.

Complex technology has become an essential aspect of everyday life. We rely on technology as part of basic infrastructure and repeatedly for tasks throughout the day. Yet, in many cases the relation surpasses mere reliance and evolves to trust in technology. A new, disruptive technology is blockchain. It claims to introduce trustless relationships among its users, aiming to eliminate the need for trust altogether—even being described as “the trust machine”. This paper presents a proposal to adjust the concept of (...) trust in blockchain applications with the tools provided by conceptual engineering. Its goal is to propose a concept of trust, that offers more than a halo term, devoid of the normative depth that the original, philosophical term actually carries. To evaluate possible concepts of trust in blockchain applications, five criteria are proposed: These criteria ensure that the conceptual relation indeed embodies trust, thereby being richer than mere reliance, and that the chosen concept highlights the active role of the trustor. While the concepts of trust in engineers and trust in algorithms have to be discarded, institutional trust emerges as a viable candidate, given some refinements. Ultimately, the concept of trust by normative expectations and attribution is suggested to capture the essence of trust in blockchain applications. (shrink)

In this paper we use a similar approach to assist users in their journey for a more sustainable lifestyle, starting with food. We employ Action Design Research (ADR) methodology to develop an application and subsequently propose design principles for developing blockchain-based applications for assisting users on their path to eating environmentally friendly food. The path to a sustainable lifestyle can be hard as individuals often do (...) not realize their personal impact towards achieving a net zero carbon future. To address this shortcoming, this study conducts an ADR experiment to create affordances for users to learn, create impact and realize that they are not alone in this journey thus motivating users to a sustainable lifestyle. The design principles that emerged from the project are design for categories and labels, design for measuring collective impact, and design for rewards and redemption. (shrink)

This paper explores the implications of tokens in the legal discourse when it comes to blockchain networks and the Fourth Industrial Revolution. In doing so, reference is made to the functioning and requirements of blockchain networks opposite to that of Statehood. Methodologically, the argument is built on the semiotic relationship between signifier and signified as outlined in De Saussure (1916) as further developed in the comprehensive work done by Lacan (Écrits (trans. Alan Sheridan), Routledge, 1977). Apparently, the factors (...) that influence this choice are considered to be of a non-legal nature. More properly, current gaps in regulation and the lack of cooperation at international level require resorting to extra-legal approaches. In contrast, the fact that economic and strategic motives play a role, does not in itself make the legal discourse devoid of any meaning. In what follows, I will concentrate on the study of factors that explain why such approach can be fruitful to establish new strategies to adjust the legal discourse to advances in technology and society. I have three reasons for selecting this topic. The first is a more pragmatic reason, based on my current research of law as a linguistic and societal phenomenon. Secondly, the topic does also touch the existing entanglement between law and economy whereby results intersect with the protection of rights inherent to members of blockchain communities. Lastly, this article relies on a dynamic concept of legal validity as a continuous process of constructing, negotiating, and reconstructing the array of blockchain communities’ interactions and transactions. Overall, these suggested methodological approaches aim at providing non-mutually exclusive reading keys to a prospective evolution of legal thought as of the Fourth Industrial Revolution changes. In contrast, they concur to provide new frames of enquiry instead of approaching these topics as objects of analysis from a sole exegetic standpoint. As a matter of fact, textualism lacks the capabilities to achieve consistent and categorial selections along with methodological exclusions that certain variants of its theories claim to accomplish. When understood against the background of a careful delineation of the choices that legal studies require, their purpose helps to give shape to a fundamental question; given the functioning of legal studies to direct choices among otherwise plausible significance of legal meaning, should they make use of an exclusively legal, or a cross-disciplinary approach? This study advocates the latter method. In this context, reference is made to the relational and representational components of property, contracts, and tokens to frame the contextual rather than the strict textual meaning of tokenisation. In this context, the above elements concur to bridge the gap among _referents_ pertaining to separate realms. Differently put, the recourse to these extra-legal categories corresponds to levels of abstraction (Tanenbaum, 1976) functioning. They refer to the structured representation of information, ranging from detailed specifics to broader concepts. Abstraction aids in comprehending complex phenomena by allowing analysis at varying granularities. Employing multiple levels facilitates a systematic understanding, enabling individuals to delve into intricate systems, discern patterns, and derive insights, thereby fostering a comprehensive grasp of multi-layered phenomena.

Modern humanities are in an ambiguous situation. Their organization is experiencing a radical challenge from the expansion of science-based assessment methods from modern business. We are talking about evaluating the results of researchers’ work on indicators from scientometrics. As a result, the evaluation subject is not the content of the research result, but their popularity and relevance to dominant views and approaches. The science organization turned upside down: it turns out not scientometrics for science, but rather science for the sake (...) of scientometrics. At the same time, digitalization and related information and communication technologies are a great achievement of civilization. Therefore, it is all the more important and useful to resist the thoughtless digitized bureaucracy using the digitization itself. This article is an attempt not to criticize digital methods, but to consider the possibilities of using blockchain technology, its advantages and the problems it generates. There are such opportunities as transparent self-organization of scientific communities, assessing the contribution and its priority, encouraging researchers. At the same time, the implementation of the blockchain implies the interest of a critically significant group of scientists with a high reputation. It is equally important to demonstrate the convenience and effectiveness of scientific work using the blockchain. The article draw attention to the significance to propose and discuss approaches to methods for assessing the quality of humanitarian and interdisciplinary studies that are adequate to the scientific practice itself, that arouse the general confidence of scientists.

This chapter discusses cryptocurrency, distributed ledger technology and blockchain tokens within the context of technological innovation, the history of money and accounting practices, and their multiple functionalities beyond those of standard currencies. This discussion is motivated by the design of cryptocurrencies for specific community needs, and to reflect anti-rival, positive sum value.

The philosophy of blockchain technology is concerned, among other things, with blockchain ontology, how it might be characterised, how it is being created, implemented, and adopted, how it operates in the world, and how it evolves over time. This paper concentrates on whether Bitcoin/blockchain can be considered a complex system and, if so, whether it is a chaotic one. Beyond mere academic curiosity, a positive response would raise concerns about the likelihood of Bitcoin/blockchain entering a 2010-Flash-Crash-type (...) of chaotic regime, with catastrophic consequences for financial systems based on it. The paper starts by highlighting the relevant details of the Bitcoin/blockchain ecosystem formed by the blockchain itself, bitcoin end users, capital gains seekers, miners, full nodes maintainers, and developers, and their interactions. Then the Information Theory of Complex Systems is briefly discussed for later use. Finally, the blockchain is investigated with the help of Crutchfield's Statistical Complexity measure. The low non-null statistical complexity value obtained suggests that the blockchain may be considered algorithmically complicated but hardly a complex system and unlikely to enter a chaotic regime.

The role that trust plays in blockchain-based systems is understood and portrayed in various manners. The blockchain technology is said to enable and establish trust as well as to redirect it, to substitute for it, and to make it obsolete. Furthermore, there is disagreement on whom or what users have to trust when using the blockchain technology: code, math, algorithms, and machines, or still human actors. This paper hypothesizes that the divergences of the depictions largely rest on (...) implicitly adhering to different accounts of trust. Thus, the goal of this paper is to outline how the current lack of a shared understanding of the term “trust” leads to diverging interpretations of the blockchain technology’s core features. Furthermore, it shows how this lack of common understanding obstructs scholars from referring to one another meaningfully in the discourse on blockchain technology. To do so, this paper outlines the most prominent depictions of the setup of relevant trust relationships within blockchain-based systems and traces their roots to different underlying assumptions on the nature of trust.

Blockchain’s language and terminology is confusing, contested, and rapidly changing. As a hype-driven technology, Blockchain is critical to an increasing number of projects that exist in a space of regulatory uncertainty. As communities of blockchain develop and evolve, the language they use to describe these functions changes. This causes concerns when attempting to have global regulatory certainty and clarity. Regulators and communities have different approaches to blockchain language, and this causes problems because of the translation between (...) practical use in a community, and the legal effects created by regulators. Of particular concern is the lack of clear expression amongst the broader community regarding the concept of blockchain-related assets as these ‘tokens’, ‘coins’, and ‘assets’ form a key part of financial regulation. This project uses semiotics to study the diverse language associated with blockchain. This analyzes a series of self-proclaimed ‘dictionaries of blockchain’ to assess key definitions, themes, perceptions, and misconceptions present in these communities. The study involved a case analysis of the terminology used in Australia’s proposed response to blockchain in comparison with that of wider communities. When comparing this to regulatory definitions and approaches, it becomes clear that this is an area that requires further attention. This project highlights the need for regulators to understand and use common terms in blockchain regulation. It is argued that this approach facilitates a better understanding of poorly understood concepts and clearly connects the law with those it intends to target. (shrink)

Blockchain technology applied to cryptocurrencies is the dominant factor in maintaining the security of cryptocurrencies. This article reviews the technological implementation of cryptocurrency and the security and stability of cryptocurrency and analyzes the security support from blockchain technology and its platforms based on empirical case studies. Our results show that the security support from blockchain technology platforms is significantly insufficient and immature. In addition, we further Zyskind and Nathan and Choi and find that the top ten platforms (...) play critical roles in security support and have significant advantages in terms of funds, duration, and human resources. Moreover, these platforms provide computational resources and benefits to the consensus algorithm selection for blockchain practitioners. Second, encryption ensures the security of cryptocurrencies. On the one hand, the digital signatures identify the identity of the signatory and the transaction. However, the principle of the hash algorithm confirms ownership. Meanwhile, SHA256 is infeasible to compute in the reverse direction and is difficult to attack. Furthermore, the records in the blockchain can be queried by every participant, making the system information transparent and open reliable. Third, compared to the study of Fu and Fang 2016, we find that the blockchain structure is composed of security components and basic components of six layers that are independent and cannot be extended completely and have a certain coupling among them. Fourth, the underlying ledger structures of Bitcoin and DAG are highly correlated to their security. Specifically, we follow Sompolinsky et al. and detect that the structure of SPECTRE ensures network security and robustness from its block production, conflict resolution, and generated trusted transaction sets. Meanwhile, the voting algorithm of SPECTRE makes resolving conflicting transactions by calculating votes and ensuring the transaction information that is virtually unable to be tampered with possible. In particular, the security calculation power of SPECTRE can reach 51% and resist “double-spend attacks” and “censorship attacks” effectively. In addition, the RDL framework of SPECTRE achieves security confirmation of transferring funds. Moreover, PHANTOM identifies evil blocks by employing block connectivity analysis and ensures its security. Eventually, we also expand the studies of and compare the basic characteristics of the protocols of Bitcoin, SPECTRE, and PHANTOM and find that protocols play imperative roles throughout the implementation process of cryptocurrency. In addition, the underlying ledger structure and consensus mechanism make up a blockchain while the confirmation time, throughput limit, and ordering are prerequisites for smart contracts. (shrink)
