A way to enable full decentralisation in our P2P- oriented economy are âSmart Contractsâ,a term coined by Nick Szabo.<br> These smart contracts enforce a set ofpredefined rules which are coded as logic to orchestrate agreement between different entities. .The current implementation makes the use of smart contracts deployed on the Ethereum blockchain that provides full-fledged car sharing functionalities along with various countermeasures to tackle malicious behaviour.

Bitcoin is part of the so-called crypto-currencies and can be defined as a universal decentralized public electronic payment system based on Blockchain technology. The problem it faces is trust in its use; therefore, the objective of this research is to analyze the factors that influence the adoption and use of Bitcoin in Mexico. For this purpose, the UTAUT2 model integrated with the trust variable, is used. The model was empirically tested by applying a survey of 106 questionnaires, under the partial least squareâs method, with structural equation models (PLS-SEM). The main results indicate that performance expectation, hedonistic motivation, habit, and its decentralization; are the main factors that influence confidence for the adoption and use of Bitcoin. The results illustrate to companies and any interested party the advantages of using Bitcoin.

In this commentary, we argue that studies similar to Cennamo, Marchesi, and Meyer (2020) should distinguish four dimensions of control in blockchain governance, all of which could be more or less decentralized. For some of these dimensions, decentralization is likely beneficial, while for others centralization may be preferable. Cennamo et al. (2020) provide evidence that the initial design stages of blockchain systems benefit from centralization. Future research is needed to provide empirical insights for other dimensions of control in blockchain governance.

Zusammenfassung Blockchain verspricht, IntermediĂ€re wie Banken ĂŒberflĂŒssig zu machen und durch dezentrale Peer-to-Peer-Netzwerke zu ersetzen. Dieser Beitrag stellt die Frage nach der Realisierbarkeit dieser AnkĂŒndigung sowie danach, welche gesellschaftlichen Implikationen damit verbunden sind. Eine historisch informierte theoretische Analyse zeigt, dass die Erzeugung von Kreditgeld durch Banken ein fĂŒr kapitalistische Gesellschaften existenzieller Vorgang ist. Die Fiktion des Geldwerts bedarf ihrerseits glaubwĂŒrdiger IntermediĂ€re, die dauerhaft in der Lage sind, die zeitliche und rĂ€umliche StabilitĂ€t des Geldes zu inszenieren. Explorative Interviews mit Akteuren im Finanzsektor in Kombination mit einer inhaltsanalytischen Auswertung von einschlĂ€gigen Blogs, White Papers und Artikeln der Wirtschaftspresse lassen vermuten, dass Blockchain IntermediĂ€re keineswegs ausschaltet, sondern diejenigen mĂ€chtiger werden lĂ€sst, die in der Lage sind, die Technologie ihren BedĂŒrfnissen entsprechend umzugestalten.

Abstract In this paper, we envision to illustrate the process to be used in developing a mobile application on the smart contract. We start by looking at what other researchers have accomplished and how we can improve on what already exists. The paper highlights the requirement gathering process, the methodology for data collection to streamline and validate the requirement, the architecture and implementation phase by analyzing the technological stack to achieve the business goal.

Blockchains as digitized, decentralized ledgers allow recordkeeping of peer-to-peer transactions, thus eliminating the need for intervening trusted third parties. This makes the technology useful in altering business processes and transactions not just across industrial sectors but also across economies. However, little research exists on the factors that impede and sponsor blockchain technology adoption in developed relative to developing country contexts. We highlight blockchain technology issues which sponsor/impede its adoption across developing/developed economic contexts. We focus on assessing the flow of money and land registries in these contexts in relation to the propensity to deploy blockchain systems. We then apply our analytical frame resting on real options principles to explore the decision point at which blockchain would be adopted relative to economic development.

As they have become leading topics of meetings, events and conferences, real-world blockchain applications have turned niche literature into a vast and complex plethora of books, articles and papers. Unlike digital payments, however, real-world applications are dependent on oracles, whose roles and implications are often neglected in the literature. The presence of oracles negatively affects decentralization and trustless consensus, generating faulty thinking or overly positive expectations. This paper aims to enlighten the state of the art of real-world blockchain applications through a systematic literature review, exploiting the oracle problem as a lens of analysis. The results support the view that almost 90% of the inspected literature is biased or incomplete.

Abstract Organizations investing in supply chain information systems struggle to ensure successful adoption and implementation. Projects fail because of technical caveats, inability to meet business needs, and poor management of implementation. Implementation of blockchain technologies across a network of supply chain partners is more complex than internally focused technologies. It is necessary for partner firms to implement, contribute, and share information, and employees to actively use the capabilities of the technology to realize potential. Blockchain technologies can substitute for traditional interfirm intermediaries acting as an unbiased software agent embedded in the supply chain network. Understanding managersâ perceptions of and willingness to use blockchain technologies is crucial for successful implementation. Integrating design theory with classic diffusion processes, we conducted a scenarioâbased roleâplaying experiment with industry professionals to examine managersâ perceptions of blockchain technologies and willingness to use. We find that trustworthiness with regard to competence and perceived distributive justice is the focal drivers of managersâ willingness to use the technology. Additionally, both risk and interactional justice are not drivers of willingness to use blockchain technology despite significant claims to that effect. We provide implications for how managers can leverage these drivers to influence supply chain partnersâ willingness to use the technology.

Abstract Existing information systems research thoroughly explains how task-technology fit and appropriation affect performance on an individual or group level. This was appropriate for many years, as technology is typically used to fulfill a certain task on these levels. Today, however, companies are tightly interconnected and rely on business networks to develop, produce, and deliver products and services. They collaboratively engage in joint implementation and utilization of new technologies that are applied and integrated into their business processes. These technologies, such as the newly introduced blockchain technology, operate across business networks and, thus, unfold their benefits not only on an individual or group level, but ideally on a network level. On this level, though, knowledge of the application and performance of information technology is still scarce. To drive the performance of technology in such networks, we investigate the impact of fit and technology appropriation on a network level. Due to the technologyâs expected impact and characteristics, we select blockchain technology to explore potential factors, impacting fit, appropriation and, in turn, performance. We draw upon a set of interviews with experts that have implemented blockchain solutions in large business network settings. Based on our analysis, we propose a comprehensive model elevating the Fit-Appropriation Model to a network level. We contribute to the general understanding of technology utilization and performance by extending existing theory to a network-level perspective. Using insights on blockchain implementations as our empirical base, we also provide guidance to business leaders, intending to connect their partners through blockchain technology.

In the post-Bitcoin era, many cryptocurrencies with a variety of goals and purposes have emerged in the digital arena. This article aims to map cryptocurrency protocols across three main defining dimensions, which are governance decentralization, security, and scalability. We theorize about the organizational and technological features that impact these three dimensions. Such features encompass roles permissiveness, validation network size, resource expenditure, and number of transactions per second. We map the different cryptocurrency constellations based on their consensus mechanisms, discussing the organizational and technological features of the various protocols applications and how they experience and play with the tradeoffs among governance decentralization, security, and scalability.

What is an economic platform? I address this question by focusing on the case of cryptocurrency exchange platforms. The research draws on interviews with platform actors, fieldwork in one exchange, and computational text analysis of the terms of service of all cryptocurrency exchanges in the world. I argue that cryptocurrency exchange platforms go beyond market processes by fulfilling a variety of functions including banking, infrastructure development, gift-giving, barter, money making, payment system operation, software production, security providing, and centralized extra-blockchain accounting. I propose the concept of âstackâ to describe such a process of socio-digital economization that takes place in these data money exchanges. Demonstrating that it is inadequate to describe platforms as mere digital infrastructures, devices, places or markets, I argue that cryptocurrency exchange platforms can best be understood as economization stacks that weave multiple layers and types of interaction, and facilitate an empirically observable range of variegated economic activities.

The importance of platformâbased businesses in the modern economy is growing continuously and becoming increasingly relevant. Specifically, the deployment of digital technologies has enhanced the applicability of twoâsided business models, enabling companies to act not just as builders and owners of assets, but also as orchestrators of external resources. Management research has, therefore, focused increasingly on the unique aspects of this model. At the center of a twoâsided platform there is a platform provider that enables a transaction between the sides, reducing the relative transaction costs. However, in recent years, a new technology emerged that challenges some of the underlying assumptions of this model: the blockchain. Blockchain enables the creation of a peerâtoâpeer network that is able to authenticate transactions, upon which applications and services may be built. It allows users to conduct transactions without the need for a central platform. We explore how blockchain technology reshapes twoâsided platforms, focusing in particular on the role of the platform provider. The research is based upon multiple case studies, using an inductive approach to explore this emerging phenomenon. Our findings show there is a significant shift in the role of the central player that links the two sides of a transaction using blockchain. We frame this as a shift from a âplatform providerâ to a âservice provider,â leveraging the blockchain as a PlatformâasâaâService. Our work examines the peculiarities of this model, unveiling new dynamics in these businesses. Specifically, we show that different variables must be considered to classify twoâsided platforms using blockchain. Furthermore, the essential characteristics of twoâsided platforms must also be enlarged. For example, traditional platform theories emphasize the importance of crossâside network externalities in creating value. In blockchainâenabled platforms however, we show the use of âtokensâ play a key role in creating different types of externalities between the two sides.

The recent emergence of blockchains may be considered a critical turning point in organizing collaborations. We outline the historical background and the fundamental features of blockchains and present an analysis with a focus on their role as governance mechanisms. Specifically, we argue that blockchains offer a way to enforce agreements and achieve cooperation and coordination that is distinct from both traditional contractual and relational governance as well as from other information technology solutions. We also examine the scope of blockchains as efficient governance mechanisms and highlight the tacitness of the transaction as a key boundary condition. We then discuss how blockchain governance interacts with traditional governance mechanisms in both substitutive and complementary ways. We pay particular attention to blockchainsâ social implications as well as their inherent challenges and limitations. Our analysis culminates in a research agenda that explores how blockchains may change the way to organize collaborations, including issues of what different types of blockchains may emerge, who is involved and impacted by blockchain governance, why actors may want blockchains, when and where blockchains can be more (versus less) effective, and how blockchains influence a number of important organizational outcomes.

We investigate the phenomenon of solidarity cryptocurrencies by combining the societal and communitarian aspects of the traditional community currencies with the the blockchain architecture chosen in a cryptocurrency project. We classify and analyze 20 selected solidarity cryptocurrencies from different countries according to three critical aspects of solidarity cryptocurrencies: scale, territorial scope and price stability. Analysis of these aspects is critical to understand the solidarity cryptocurrency concept that connects the originally separated universes of traditional community currencies and cryptocurrencies. This paper contributes to explain the emergent solidarity cryptocurrencies phenomenon by describing particular types captured by our classification. The main findings about solidarity cryptocurrencies in this study are, first, the alignment between type of governance and the respective architecture platform; second, those with closed governance are more likely to be pegged on fiat currencies or other stable measures; third, those focused on local issues tend to have a higher level of adoption.
