In today’s world almost all hospital uses hardcopy for patient data store and for booking appointment. All patient data is available on paper and user need to manage that all over he goes. Consider ’A’ patient got admitted in City Pune, all his data is stored on paper and what medicines he took. All the info about his health is stored there. After someday ‘A’ patient gone to another city far away without carrying any documents and there he got and health emergency and is not in condition of speaking and need urgently help. But due to lack of info available about patient doctor could not urgently take decisions. So, to reduce this risk our system is developed. The distribution of Health records becomes a time consuming and expensive process when we use the traditional client-server healthcare data management system where each hospital/clinic maintains its own database of patients’ medical records. A patient’s treatment is further delayed if the patient moves from one hospital to another hospital across different regions or countries. Moreover, most of the time a patient must repeat several laboratory and radiology tests. So, to address this the patient’s medical data from different hospitals are stored in a Blockchain based storage making it easily accessible by patients and the hospitals. And the pharma company will be able to store the information of medicines and medicals will be available to verify the medicines if they are from trustworthy companies.

The greatest advantage that Web3 applications offer over Web 2.0 is the evolution of the data access layer. Opaque, centralized services that compelled trust from users are replaced by trustless, decentralized systems of smart contracts. However, the public nature of blockchain-based databases, on which smart contracts transact, has typically presented a challenge for applications that depend on data privacy or that rely on participants having incomplete information. This has changed with the introduction of confidential smart contract networks that encrypt the memory state of active contracts as well as their databases stored on-chain. With confidentiality, contracts can more readily implement novel interaction mechanisms that were previously infeasible. Meanwhile, in both Web 2.0 and Web3 applications the user interface continues to play a crucial role in translating user intent into actionable requests. In many cases, developers have shifted intelligence and autonomy into the client-side, leveraging Web technologies for compute, graphics, and networking. Web3's reliance on such frontends has revealed a pain point though, namely that decentralized applications are not accessible to end users without a persistent host serving the application. Here we introduce the Non-Fungible Program (NFP) model for developing self-contained frontend applications that are distributed via blockchain, powered by Web technology, and backed by private databases persisted in encrypted smart contracts. Access to frontend code, as well as backend services, is controlled and guaranteed by smart contracts according to the NFT ownership model, eliminating the need for a separate host. By extension, NFP applications bring interactivity to token owners and enable new functionalities, such as authorization mechanisms for oracles, supplementary Web services, and overlay networks in a secure manner. In addition...

Introduction: Scientists use donated biospecimens to create organoids, which are miniature copies of patient tumors that are revolutionizing precision medicine and drug discovery. However, biobanking platforms remove donor identifiers to protect privacy, precluding patients from benefiting from their contributions or sharing information that may be relevant to research outcomes. Decentralized biobanking (de-bi) leverages blockchain technology to empower patient engagement in biospecimen research. We describe the creation of the first de-bi prototype for an organoid biobanking use case. Methods: We designed and developed a proof-of-concept non-fungible tokens (NFTs) framework for an organoid research network of patients, physicians, and scientists within a synthetic dataset modeled on a real-world breast cancer organoid ecosystem. Our implementation deployed multiple smart contracts on Ethereum test networks, minting NFTs representing each stakeholder, biospecimen, and organoid. The system architecture was designed to be composable with established biobanking programs. Results: Our de-bi prototype demonstrated how NFTs representing patients, physicians, scientists, and organoids may be united in a privacy-preserving platform that builds upon relationships and transactions of existing biobank research networks. The mobile application simulated key features, enabling patients to track their biospecimens, view organoid images and research updates from scientists, and allow physicians to participate in peer-to-peer communications with basic scientists and patients alike, all while ensuring compliance with de-identification requirements. Discussion: We demonstrate proof-of-concept for a web3 platform engaging patients, physicians, and scientists in a dynamic research community, unlocking value for a model organoid ecosystem. This initial prototype is a critical first step for advancing paradigm-shifting de-bi technology that provides unprecedented transparency and suggests new standards for equity and inclusion in biobanking. Further research must address feasibility and acceptability considering the ethical, legal, economic, and technical complexities of organoid research and clinical translation.

Web 3.0 or Web3 is the next-generation Internet paradigm, which aims to realize the vision of a decentralized and open Web that provides greater utility to users. Due to the rapid development of technologies, such as augmented reality (AR) and extended reality (XR), the industrial metaverse, which is an immersive and interactive simulation mirroring real-world processes, systems, and objects, is gradually becoming a reality. Simultaneously, the industrial metaverse represents a new paradigm for the next generation of industrial transformation. However, data communications supporting the industrial meta-verse require extremely high reliability and low latency to ensure a high level of quality of service (QoS). Therefore, achieving an immersive and interactive industrial metaverse poses significant challenges to data communications. In this article, we first review the big picture of the industry and high-tech companies of industrial metaverse. Subsequently, we explore the application potential of sixth-generation (6G) communication technology and various enabling technologies, such as ultra-reliable and low-latency communication (URLLC) and reconfigurable intelligent surfaces (RIS) in the industrial metaverse. Then, we propose an RIS-enhanced communication paradigm to solve the challenges of privacy, security, reliability, and latency for industrial meta-verse applications. Finally, we discuss potential communication research directions for the industrial metaverse.
Boletus have become popular in recent years. However, as a kind of food, its edible safety has been widely concerned. Therefore, it is necessary to trace its origin. In this paper, a total of 1195 samples of 8 kinds of common boletus in southwest China were collected. Its Infrared Spectroscopy were obtained by FTIR spectrophotometer and converted into 2DCOS spectral images. The dataset was pre-processed and sent into ResNet-20 model for training. The model achieved an accuracy rate approaching $100 \%$ with minimal loss. By building a blockchain on the FISCO BCOS platform, a traceability framework for the supply chain of Boletus based on a consortium blockchain and a smart contract was established. Based on the results of ResNet-20 model, an Android app was developed and deployed using Java in Android Studio. After detecting Boletus products, upload the information to the blockchain to generate a traceability ID. Users can input these traceability IDs in the app to access Boletus information. Additionally, a visualization platform was developed using Echarts and Python, which utilizes Web3.js to retrieve and display relevant data from the blockchain. This research can be utilized as a point of reference for tracing Boletus.
Web3 is leading a wave of the next generation of web services that even many Web2 applications are keen to ride. However, the lack of Web3 background for Web2 developers hinders easy and effective access and transition. On the other hand, Web3 applications desire encouragement and advertisement from conventional Web2 companies and projects due to their low market shares. In this article, we propose a seamless transition framework that transits Web2 to Web3, named WEBTTCOM [WEBTTCOM stands for Web2 (two)–Web3 (three) Communicator], after exploring the connotation of Web3 and the key differences betweenWeb2 andWeb3 applications.We also provide a full-stack implementation as a use case to support the proposed framework, followed by performance evaluation and surveys with ~1000 participants that show ~80% positive and ~20% neutral responses. We confirm that the proposed framework WEBTTCOM addresses the defined research question, and the implementation well satisfies the framework WEBTTCOM in terms of strong necessity,usability, andcompletenessbased on the survey results.
Technology formally entered academia around 1450s AD when the printing press started being used for making books available to learners. Long after about seven centuries, gradual adoption of information, communication, and digital technologies brought overwhelming changes for speedier, more effective, and impactful teaching, learning, training, and evaluation. These rendered both synchronous and asynchronous modes much smarter and more exciting particularly for generations Y and Z. The advent and evolution of Web1 to Web3 has made globally accessible distance learning an indispensable part of contemporary education management development systems. Efforts have been made to narrate certain major dimensions and the collective effects of all these technologies culminating in EdTech. It has also deleneated the taxonomies behind and the impacts of AI and Generative AI on EdTech.
The penetration of electric vehicles (EVs) in the energy market has become a immersive paradigm for facilitating greener environment by mitigating the disadvantages of the fossil-fuel vehicles. Nevertheless, it becomes critical for charging station (CS) to handle huge number of EVs further leading to the uncoordinated and inefficient charging. Moreover, none of the authors have considered the possible EV charging scenarios for allocation at the CS. Thus, we have designed an Ethereum blockchain-based decentralized application for EV charging at the CS along with the energy trading between prosumer and consumer EVs. Further, we have formulated charging scenarios based on the energy demand and type of EV (emergency and high authority). We have deployed the smart contract in Remix Integrated Development Environment (IDE) and further built a decentralized application using Web3 to made charging allocation accessible to the EVs. Finally, the simulation results of the proposed smart contract for the application is evaluated in terms of gas consumption and cost analysis with the help of deployed smart contract in the Remix IDE.

This paper presents the design, deployment and qualitative study of a large-scale, public, generative art exhibition, through which passers-by could create artworks, and mint a non-fungible-token (NFT). Following the month-long exhibition, during which 229 anonymous participants produced artworks, 69 non-transferable NFTs were minted, we surveyed (33) and interviewed (14) expert and novice participants about their experiences. We explored contemporary challenges of owning digital things, and the extent to which NFTs, and 'Web3' technologies offer meaningful forms of ownership. Our findings describe how the inability to trade this NFT, and its unique circumstances of acquisition, made it meaningful in ways that extended beyond its immediate (limited) utility and offered participants something through which to construct identity. Reflecting on the aspirations, contradictions, and misconceptions of forms of ownership enabled by NFTs, we conclude with proposals for renewed attention in HCI to the nature of digital possessions, and the potential for 'ownership design'.
In this article, Erik Bordeleau presents, as a form of anarchic resistance to the capitalist logic, The Sphere project in which he is involved. For the author, The Sphere can be understood as a virtual space for exchanges between artistic processes and financing practices, whose root comes from a need to give new understanding to the meaning and use of digital media. He also states that the project is specifically interested in promoting the integration of creators, producers and the public, enabling an ecosystem that facilitates the alignment between interests and purposes through a spirit of speculative generosity. Therefore, the author uses reflections from renowned figures in the intellectual world, such as, for example, Deleuze and Guattari, Hito Steyerl, Jean-Luc Nancy, Jacques Rancière and Yuk Hui fundamentally to propose the defense of the need for a new look at crypto and blockchain technology, considering the decentralization provided by DAOs and Web3. Generating new forms of rhizomatic organization, instead of nostalgic notions of mass organization, ends up producing the possibility of codifying relations of equity through vectors of mutual participation.
This chapter explores the evolving legal context surrounding the ownership of digital assets, delving into the ramifications of legal frameworks such as property law, copyright, and data protection for the creative digital industry. We underline the importance of the nexus between ownership technology and legal reform, which will bear profound implications for the digital creative economy. Focusing on the recent consultation and recommendations by the Law Commission of England and Wales on this topic (2022–3), we suggest incremental legal adjustments as alternative strategies. We juxtapose this backdrop with a case study on non-fungible tokens (NFTs), which are envisioned as a “property layer” in the emerging Web3 Internet. The ascent of NFTs, evidenced by eye-catching transactions in the art world, underscores a paradigm shift in digital ownership. However, NFTs and decentralised technologies, while holding substantial promise, do not yet fully align with creatives’ desired rights. In order to provide legal certainty, we emphasise the need for nuanced understanding and collaboration among legal scholars, computer scientists, and creative industry stakeholders in order to reimagine property rights in the digital sphere, shaping the future of digital assets and their place within the creative economy together.
Web services that use a blockchain and crypto-assets (Web3 services) improve user privacy by anonymous logins using wallet addresses. However, since many users list their account identities (IDs) on social networking service (SNS) profile pages and reuse their account IDs for self-branding and curation purposes, which increases the risk of de-anonymization on Web3 services by linking these accounts. If such high-risk SNS accounts hold large amounts of crypto-assets, they are subject to account hijacking and spoofing attacks for financial gain. In this study, we proposed a method to discover highly relevant SNS accounts from a seed account on Web2 and Web3 SNSs and estimate their account ownership. We applied our method to 480 seed accounts of 9 different SNSs and discovered 1,233 new accounts. We found that SNSs with multiple URL input forms on their profile setting pages linked more accounts and revealed that 207 out of 253 (81.8%) users reused their IDs across different SNSs. We identified 26 accounts linked to personal and crypto-asset information that are at risk of de-anonymization. Our user study using crowdsourcing services showed that as many as 232 (40.8%) out of 568 respondents do not understand the traceability of blockchain transaction histories. We examined the security and privacy risks caused by account listing and ID reuse, and made recommendations for service providers and users based on our findings.
An all-encompassing and flexible framework that links theoretical principles and actual execution is required for the creation of hardware for Web3.0 and edge intelligence. Decentralized identification, semantic data, blockchain, and zero-knowledge proofs are just few of the concepts that are examined in depth to provide the groundwork for this technique. The main goal is to figure out what kinds of hardware are needed to implement these theoretical principles. Subsequently, the technique continues to extract the hardware requirements, distinguishing the unique demands, problems, and performance criteria important for enabling Web3.0 and edge intelligence. These needs include a wide range of topics, including performance, safety, efficiency, scalability, and even compatibility. Once the theoretical principles and hardware requirements are fully understood, the technique moves on to the design step. Key to realizing these abstract ideas is the development of specialized hardware architectures and components. Based on the outcomes of the performance assessment, iterative refinement is carried out to fix the hardware's flaws and enhance its functionality. As a result of this iterative process, hardware is kept up to date to suit the ever-shifting requirements of Web3.0 and edge intelligence. The suggested technique concludes with an emphasis on flexibility and future-proofing in light of the everchanging nature of Web3.0 and edge intelligence. Keeping up with technology developments and reevaluating the hardware design as needed are both part of this process.

Since the early developments of Web3 and the Metaverse, the fashion industry has been actively launching initiatives, especially through gamification, Non-Fungible Tokens (NFTs) and shopping experience. Up until now the academic literature relating to the implications for fashion brands in a digital fashion marketing context has been scarce. Through a systematic content analysis of 235 articles published between 2021 and 2023 in Vogue Business and The Business of Fashion, this research has focused on the main brands and uses of the Metaverse, as well as their real applications. Through a thorough analysis, this research reveals that the most active fashion sub-industries on the Metaverse are those relating to luxury, sportswear and beauty, with Nike, Gucci and Hermès emerging as the leading brands. Furthermore, when it comes to fashion and the Metaverse, the most popular topics relate to NFTs and gamification, to the point that they are used as synonyms of the Metaverse. This practice creates confusion, not only in terms of the meaning of the term “metaverse”, but also regarding its implications for fashion brands. Finally, the study identifies issues that demand further analysis in subsequent academic research regarding the notion of falsity and the Metaverse.
The blockchain ecosystem, particularly with the rise of Web3 and Non-Fungible Tokens (NFTs), has experienced a significant increase in users and applications. However, this expansion is challenged by the need to connect early adopters with a wider user base. A notable difficulty in this process is the complex interfaces of blockchain wallets, which can be daunting for those familiar with traditional payment methods. To address this issue, the category of "embedded wallets" has emerged as a promising solution. These wallets are seamlessly integrated into the front-end of decentralized applications (Dapps), simplifying the onboarding process for users and making access more widely available. However, our insights indicate that this simplification introduces a trade-off between ease of use and security. Embedded wallets lack transparency and auditability, leading to obscured transactions by the front end and a pronounced risk of fraud and phishing attacks. This paper proposes a new protocol to enhance the security of embedded wallets. Our VELLET protocol introduces a wallet verifier that can match the audit trail of embedded wallets on smart contracts, incorporating a process to verify authenticity and integrity. In the implementation architecture of the VELLET protocol, we suggest using the Text Record feature of the Ethereum Name Service (ENS), known as a decentralized domain name service, to serve as a repository for managing the audit trails of smart contracts. This approach has been demonstrated to reduce the necessity for new smart contract development and operational costs, proving cost-effective through a proof-of-concept. This protocol is a vital step in reducing security risks associated with embedded wallets, ensuring their convenience does not undermine user security and trust.
Abstract: Criminal activities in India are on the rise, with many incidents going unreported. Despite the availability of an online portal for storing the First Information Reports (FIRs) handwritten FIRs always will remain common due to some of the traditional methods and practices. And probably in most cases, the complainants should personally visit the police stations in order to file a offense report. Crime and Criminal Tracking Network and Systems (CCTNS) was launched in 2010 for national wide e-governance, it will operates on a centralized system and it is particularly limited to some individual states. Therefore, there is a need for the decentralized solution in order to ensure failure of a single point and secure managing of criminal complaints from the unauthorized access.
Distributed ledger technology (DLT) as an rising alternative for improving safety and transparency in reportsharing structures is very promising. In this regard, the existing have a look at is providing a blockchain-based system for file sharing where allotted ledgers may be used to conquer the restrictions of centralized structures. To make certain that the records shared is secure, unchangeable, and necessary, the gadget applies consensus, hashing, and encryption strategies. The use of clever contracts lets in for automatic execution of documentsharing transactions in a steady manner, thus lowering the capability risks associated with fraud or prison troubles. Furthermore, users are furnished with more control by letting them specify permissions and get right of entry to constraints for his or her documents. To make it smooth to use the blockchain and combine those technologies, the system makes use of decentralized file storage primarily based on Blockchain. Also, the databases used by this machine are FileCoin for login information and Web3 Token for document sharing and storing, which brings protection into the scene, makes storage decentralized, and increases transparency.
