Summary: The usage of blockchain technology has been significantly expanded with the introduction of smart contracts and blockchain oracles. However, the validity and accuracy of off-chain data provided by oracles can be questionable, compromising the transparency and immutability of blockchain. In this paper, a graph-based profiling method is proposed to determine the trustworthiness of blockchain oracles by constructing a graph with oracles as nodes and cumulative average discrepancies of data as edge weights. The evaluation study conducted on the Ethereum network demonstrates an accuracy of around 93% in identifying trustworthy data sources.

Summary: Blockchain technology has been successfully used in various applications for international asset transfers and domestic payments, leading to a paradigm shift in the payment industry with more liquidated and automated payment processes. While BCT tends to replace conventional payment methods in supply chain, some payment conditions, such as arrears, remain unresolved. A new architecture based on smart contracts has been proposed to improve payment flexibility, with significant theoretical and practical significance in allowing enterprises to fully utilize future resources.

Summary: In this paper, a blockchain-based framework for the online sale of pharmaceutical products is proposed. It eliminates intermediaries such as hospitals or pharmacies and utilizes Ethereum smart contracts to monitor interactions, track transactions, and ensure secure payment dispersal. The smart contracts also regulate the interaction between sellers and consumers, monitor IoT container status, and provide full notification to consumers. Special cases such as consumer refunds are handled to ensure the safe delivery of medicines.

Summary: Blockchains are blind to the real world and rely on third-party oracles for external data. The implementation of oracles is controversial and brings back issues of trust and single points of failure. Blockchains also lack interoperability, preventing the flow of liquidity between different chains. Wrapped tokens are one solution to achieve interoperability, but their issuance involves considerations of trust and third-party involvement.

Summary: Digital transformation at the micro level involves changes in roles, skills, leadership styles, and managerial approaches within organizations. Therefore, understanding individual attitudes and behaviors that drive digital transformation is crucial. This study examines digital transformation at the micro level by conducting a multiple-case study of 38 Italian firms, including seven large firms and 31 small and medium-sized enterprises (SMEs), allowing for cross-case analysis. Findings suggest that approaches differ for managers in SMEs and large firms, with large firms employing a conductor approach and SMEs adopting a peer-tutor approach characterized by bottom-up, informal, persuasive, and empathic methods.

Summary: Grounded in dynamic capabilities theory, this study examines the impact of firms' technological orientation (TO) on their resilience to the Covid-19 pandemic (RTC), taking into account the mediating role of their digital strategy maturity (MDS). The study surveyed 186 firms operating in Germany and Italy and used covariance-based structural equation modeling (CB-SEM) and bootstrapped regression analysis to test the hypotheses. The results suggest that TO positively affects MDS, leading to higher RTC, while the relationship between TO and RTC is not significant. The study contributes to the knowledge of dynamic capabilities theory and emphasizes the importance of developing a mature digital strategy for organizational resilience in the face of disruptive changes.

Summary: Public management reforms have resulted in re-stratification of professions and the emergence of administrative elites. We examine this phenomenon in English publicly owned hospitals and find that the social status hierarchy of medicine has adapted to management demands. However, the establishment of a management criterion for seniority is only evident under certain conditions, supporting the status position of elite doctors.

Summary: Innovation is important for economic growth, and the role of disruptive innovation in promoting growth is highly regarded. This study examines the impact of entrepreneurial orientation (EO) and digitalization strategy on firms' ability to develop disruptive innovation. Based on survey data from 242 firms, the results show that EO has a significant positive effect on disruptive innovation. However, highly entrepreneurially oriented firms perceive a digitalization strategy as a metaphorical cage for disruptive innovation. On the other hand, a digitalization strategy supports disruptive innovation when firms have lower entrepreneurial orientation. The findings suggest that firms should focus on EO to enable disruptive innovation and adjust digitalization strategy based on the level of EO.

Summary: Before alternative blockchains like Ethereum emerged, Bitcoin held the future of decentralization. Early developers aimed to decentralize traditionally centralized applications using Bitcoin's potential, but faced challenges with unsuitable non-trustless oracles. This paper retraces the birth of oracles on Bitcoin by interviewing early developers and examining early forums and repositories, discussing the evolution of protocols and encountered difficulties. It also analyzes technical and social barriers to building oracles on Bitcoin and the transition to Ethereum.
