At present, blockchain technology has been applied in different fields such as finance, Internet of Things, logistics, digital copyright, and public services, but it is less used in the field of paper-cut animation. Therefore, the use of blockchain to design a copyright protection model for paper-cut animation design based on blockchain is crucial to the progress of paper-cut animation design. This work combines various technologies such as blockchain technology, InterPlanetary File System (IPFS) technology, and Node.js technology for integrated design and construction. In the construction of the system model, the relevant characteristics of the blockchain technology show that the blockchain can provide a new and effective method for digital copyright protection; IPFS technology provides distributed and secure storage for massive amounts of oil and gas knowledge and achievement data; and the relevant development framework and technical characteristics of Node.js technology provide a reliable programming foundation for the realization of the system. Through the construction of the digital copyright protection system model based on the blockchain, the blockchain technology is used to realize the protection of the digital copyright of the knowledge achievement data of paper-cut animation. The results show that the model has high security and is more economical and practical than other existing models. In a word, the copyright protection model of paper-cut animation design based on blockchain can fully protect the rights and interests of creative talents of paper-cut animation, thereby promoting the progress of paper-cut animation industry.

These days, we receive most information through digital mediums such as emails and social networking applications. Investigating the characteristics of human-paper interactions can help us design more meaningful interactions and better understand why people use paper documents in the age of digitalization. In this study, the interaction of people with physical documents was studied through a mixed-method of conducting a literature review, gathering expert opinions, interviewing subjects, and analysing Instagram photos. By codifying the gathered information, the human-paper interaction framework was developed. This framework articulates the advantages of physical documents compared to electronic documents and serves researchers and practitioners by providing insightful human factors about human-document interaction. Finally, we propose six design themes as the solutions to the findings of this study. These implications can provide practical foundations for future design and research.

Governance for centralized organizational structures has long roots and well-developed frameworks, including for various specialty areas, such as IT or data governance. However, the introduction of blockchain technology as a supportive tool for implementing decentralized organizations requires a renewed focus for research in the area. The paper utilizes empirical data from blockchain ecosystems in the form of white papers (public communique of intention) to analyze their governance intentions. The empirical findings are based on a review of 241 blockchains and distributed ledger technology white papers, out of which 67 include explicit descriptions of how governance should be organized in the ecosystem. Our empirical research distinguishes between three categories of governance: objectives, mechanisms, and stakeholders. We further identify 28 features for these categories, which are described in an open encoding format. Hence, the paper contributes to the emerging blockchain research field, particularly to the decentralized aspects of blockchain governance research. This research also reveals that blockchain governance does not receive the attention it should as a large majority of ecosystems have not disclosed their governance intentions. The results can be utilized as a framework for future research. The results can also be helpful for industry when designing and developing governance systems.

The present study aims to highlight the features of Connected Papers, a visual tool that can help researchers find and explore academic papers in their literature search. The authors describe how Connected Papers allow to create a network of all the literature available related to a chosen paper. One can use Connected Papers to pull together related papers on a chosen topic and see prior and derivative works based on that topic. Using the Connected Papers tool authors attempt to visualize the key literature on the topic "Blockchain in libraries." To date, most Blockchain technology applications in libraries are still in the conceptual stage. However, sooner or later, the development and implementation of the technology are expected to facilitate the transformation of how libraries provide services and organize information. This study contributes to examining the research being done to explore the potential of Blockchain technology in libraries through mapping and visualization. The paper is original in terms of the Visual tool used "Connected Papers." [ABSTRACT FROM AUTHOR]

With the rapid development of the autonomous world, local decision making between devices is becoming important. This article provides a new paradigm (Rock-Paper-Scissors-Hammer: RPSH) that can reduce the number of conflicts or decision draws and thus increase the throughput of autonomous devices while reducing the kept number of records or transactions. The paradigm requires a sealed envelope protocol and sequential message passing between both parties to decide unanimously a winner between the two participants without a third-party mediation. The message passing proposes a detailed record in a blockchain-like format that is not corruptible and is verifiable for conflict resolution. A simulated IoT environment is created to show the advantage of the proposed protocol and it shows significant reduction in mean efforts due to the elimination of draws or undecided situations. Autonomous devices, such as cars, need to maintain meticulous, lightweight, but blockchain-like record keeping for insurance settlements or conflict resolutions; that archival data size is significantly reduced by the RPSH protocol.

Abstract Blockchain can be thought of as a distributed database allowing tracing of the origin of data, and who has manipulated a given data set in the past. Medical applications of blockchain technology are emerging. Blockchain has many potential applications in medical imaging, typically making use of the tracking of radiological or clinical data. Clinical applications of blockchain technology include the documentation of the contribution of different “authors” including AI algorithms to multipart reports, the documentation of the use of AI algorithms towards the diagnosis, the possibility to enhance the accessibility of relevant information in electronic medical records, and a better control of users over their personal health records. Applications of blockchain in research include a better traceability of image data within clinical trials, a better traceability of the contributions of image and annotation data for the training of AI algorithms, thus enhancing privacy and fairness, and potentially make imaging data for AI available in larger quantities. Blockchain also allows for dynamic consenting and has the potential to empower patients and giving them a better control who has accessed their health data. There are also many potential applications of blockchain technology for administrative purposes, like keeping track of learning achievements or the surveillance of medical devices. This article gives a brief introduction in the basic technology and terminology of blockchain technology and concentrates on the potential applications of blockchain in medical imaging.

Clear legal content of white papers provides certainty, stability and trust in the relations between all the participants in initial coins offering (ICO) procedures and contributes to the successful introduction of blockchain technologies in business. A white paper defines the relationship and interaction between a regulated social reality and program code, which is by itself not susceptible to legal regulation. This article investigates the legal conditions of the white papers that describe the projects of ICO. The author provides a legal analysis of numerous white papers published during ICO implementation around the world. Based on extensive data on implemented ICO projects, the correlation between the legal content of a white paper and the amount of funds collected as a result of the ICO is considered. Having analysed the determinants of the white paper legal content, the author suggests the legal provisions that any ICO white paper should have. [ABSTRACT FROM AUTHOR]

This study explored the association between renewable energy uptake and digitalization in the sector by reviewing relevant literature (published 2010–2022), with the aim of identifying the existing utilization of digital technologies within the sector, challenges to adoption, and future prospects. Different search engines (SCOPUS, Web of Science, and Google Scholar) were used to locate relevant papers and documents. The results revealed the high significance of digital technologies in supporting the renewable energy sector, with high costs and security risks representing the key challenges. Most papers reviewed had a positive outlook, but recommended further research and development for effective energy transition and resilient infrastructure. The current drivers of the integration of digital technologies to support the diffusion of renewable energy sources appear to extend beyond energy demand and involve many aspects of sustainability and sustainable development. Compared with previous reviews, this work has unique scope and novelty since it considers the bigger picture of the coupling between digitalization and the renewable energy sector, with a greater focus on critical areas in these two interconnected bodies that need to be addressed. The relatively small sample of relevant papers (69 from 836 hits) located in the literature review confirms the need for more research covering the subject in greater depth. [ABSTRACT FROM AUTHOR]

By utilizing smart contracts, which are essentially scripts that are anchored in a decentralized manner on blockchains or other similar infrastructures, it is possible to make the execution of predetermined procedures visible to the outside world. The programmability of previously unrealized assets, such as money, and the automation of previously manual business logic are both made possible by smart contracts. This revelation inspired us to analyze smart contracts in blockchain technologies written in English between 2012 and 2022. The scope of research is limited to the journal. Reviews, conferences, book chapters, theses, monographs, and interview-based works, and also articles in the press, are eliminated. This review comprises 252 articles over the last ten years with "Blockchain", "block-chain", "smart contracts", and "smart contracts" as keywords. This paper discusses smart contracts' present status and significance in blockchain technology. The gaps and challenges in the relevant literature have also been discussed, particularly emphasizing the limitations. Based on these findings, several research problems and prospective research routes for future study that will likely be valuable to academics and professionals are identified. [ABSTRACT FROM AUTHOR]
