With the advent of the Internet of Things (IoT), a new transformation is predominant in the manufacturing industry, termed Industry 4.0. The revolution of IoT with artificial intelligence, Web3, robotics, and automation has transformed the traditional manufacturing system into a smart manufacturing system (SMS) by adding an intelligent component capable of automatic data collection through using sensors, processing data autonomously, and controlling machines remotely. However, adding automated intelligence, autonomous systems, and real-time data processing presents an insecure surface to cyber attackers to penetrate these cyber-physical systems (CPSs) and cause physical damage. This chapter presents a detailed discussion of cyber threats and incidents in the intelligent manufacturing industry, along with the available acceptable mitigation strategies. A taxonomy of cyber attacks on intelligent manufacturing systems clearly shows the difference between information technology threats and smart manufacturing cyber-threats. A detailed discussion on the limitations of SMSs in implementing cyber security is presented. Finally, some innovative machine learning–based security mechanisms (ML-based intrusion detection systems) are discussed that promise to detect anomalies/intrusions in such systems.
The secure management and sale of digital assets has become a critical problem in an increasingly digitized environment. This project intends to address this issue by creating decentralized applications (dApps) that use blockchain technology to provide secure and efficient digital asset management, with a focus on NFTs. The NFT marketplace includes secure wallet connections, NFT image creation, minting, the marketplace, and profile management. Solidity-based smart contracts are utilized to create the NFT Marketplace back end, and IPFS is used for storage. The NFT Marketplace's front-end development uses React JSX and the web3js framework, allowing developers to connect to the Ethereum network. NFT Marketplace may assist creators in selling their art through a smart contract system, in which the artwork's ownership transfers to the new owner upon submission of a digital certificate.
During the COVID-19 outbreak, due to the lockdown, all museums and galleries were closed for more than a year. So, the buying and selling of physical arts have dropped. This project aims to overcome this challenge by developing a decentralized application called Decentralized NFT Exchange. The decentralized non-fungible token (NFT)exchange includes features such as secure wallet connections, NFT creations, buying, selling, and profile management. The back-end of the decentralized NFT exchange is implemented using Solidity-based smart contracts, while InterPlanetary File System (IPFS)is used for decentralized storage. Front-end development of decentralized NFT exchange is implemented using React JSX and framework web3.js that helps developers connect to the Ethereum network. Decentralized NFT can help art creators sell their artworks using a smart contract system where the ownership of the work will become the property of the new owner with proof of a digital certificate. The project demonstrates the practical application of blockchain technology in developing decentralized applications (DApps)for secure and decentralized digital asset management. Overall, Decentralized NFT might be a solution for the copyright of work in the future and the project contributes to secure and decentralized digital asset management

Differential privacy offers rigorous protections for emerging paradigms like federated machine learning, decentralized analytics, and web3 applications. The parameters E (epsilon) and5)-differential privacy while sustaining utility with an average error of only 4.5% compared to non-private histograms, underscoring the importance of formally tracking cumulative privacy loss. Our framework provides a practical solution for measurable privacy-preserving machine learning pipelines without degrading accuracy or utility. By interfacing with diverse mechanisms and adapting noise to empirical sensitivities, we facilitate precise reasoning of privacy risks throughout model life cycles. We also analyze privacy parameter implications across application domains. This paper lays a rigorous foundation for developing trustworthy AI systems that protect sensitive data.
Blockchain and Web3 technologies were originally understood in a narrowly financial context, associated with cryptocurrencies such as Bitcoin. Non-fungible tokens, or NFTs, have put music (and other creative economy use cases such as art and gaming) center stage. Yet there remains a widespread misconception that speculative investments in cryptocurrencies and NFTs are the be-all and end-all of Web3. This chapter examines the potential impact of blockchain technology on the music industry from a more holistic perspective. Specifically, its contribution lies in proposing four lenses through which we can view Web3 music: financial, social, environmental and experiential. By examining the value of tokens – fungible as well as non-fungible – in terms that go beyond short-term price fluctuations, I hope to deepen our understanding of cultural value in Web3 and beyond.
Abstract In Web3 social platforms, i.e. social web applications that rely on blockchain technology to support their functionalities, interactions among users are usually multimodal, from common social interactions such as following, liking, or posting, to specific relations given by crypto-token transfers facilitated by the blockchain. In this dynamic and intertwined networked context, modeled as a financial network, our main goals are (i) to predict whether a pair of users will be involved in a financial transaction, i.e. the transaction prediction task , even using textual information produced by users, and (ii) to verify whether performances may be enhanced by textual content. To address the above issues, we compared current snapshot-based temporal graph learning methods and developed T3GNN, a solution based on state-of-the-art temporal graph neural networks’ design, which integrates fine-tuned sentence embeddings and a simple yet effective graph-augmentation strategy for representing content, and historical negative sampling. We evaluated models in a Web3 context by leveraging a novel high-resolution temporal dataset, collected from one of the most used Web3 social platforms, which spans more than one year of financial interactions as well as published textual content. The experimental evaluation has shown that T3GNN consistently achieved the best performance over time and for most of the snapshots. Furthermore, through an extensive analysis of the performance of our model, we show that, despite the graph structure being crucial for making predictions, textual content contains useful information for forecasting transactions, highlighting an interplay between users’ interests and economic relationships in Web3 platforms. Finally, the evaluation has also highlighted the importance of adopting sampling methods alternative to random negative sampling when dealing with prediction tasks on temporal networks.
The global transition towards Web3 is giving rise to many blockchain networks, each with its native cryptocurrency. Ethereum is used for decentralized applications, Bitcoin is used for investment, and Polygon is used for scalability solutions. Furthermore, a few well-known blockchain platforms have implemented interoperability features, meaning users can now send wrapped tokens around different blockchains. User assets are then distributed across multiple blockchain networks and wallets. This means user assets are already distributed across multiple tokens on different blockchain networks. This work presents a web application that allows you to visualize your assets distributed across different blockchain networks and wallets. Notably, this work supports the straightforward integration of secondary wallets with user accounts. In addition, this work supports tracking the historical user asset transfer requests, including incoming and outgoing ones, and storing the metadata associated with each asset transfer, including its corresponding proof’s Content Identifier (CID) after zkSNARKs proof generation by hosting it on the InterPlanetary File System (IPFS).

Blockchain is at present the most well-known innovation. Blockchain offers your applications a safer, changeless, and decentralized stage. Web 3.0 is another new innovation. A ton of tremendous enterprises control a ton of the web and figure out what is and isn’t permitted. Web3 is unmistakable in that clients make, make due, and own it as opposed to being represented by a solitary element. This suggests that instead of an incorporated government, commoners have more control. Non-Fungible Tokens, or NFTs, are basically a pristine strategy for computerized thing assortment. They don’t need agents and give direct help to vocalists, competitors, and craftsmen. NFTs give makers a new chance to share and adapt their work.Digital products were challenging to showcase in the past since they were effectively duplicated and guaranteed by others. Our goal is to foster a stage that permits clients to look for, rundown, or buy NFTs without the requirement for a focal body to screen purchaser vender collaborations. It’s more decentralized and evenhanded along these lines. This study researches the production of an instinctive NFT commercial center application that consolidates Ethereum, Metamask, and Ganache IPFS. Further developing client communications inside the NFT biological system is the principal objective.
This extended abstract paper presents a vision for data and AI requirements governance in distributed System-of-Systems (SoS) that involve multiple parties and dynamic alliances, such as in the defense domain (e.g. different weapon systems on the battlefield). The paper proposes to use web3 technologies, such as distributed ledger and secure multi-party computation, to enable collaborative analytics and data interoperability among the SoS members, while preserving their sovereignty and privacy. The paper also suggests a model-driven approach that can generate executable code and workflows from a common ontology and a semantic mapping tool, which can facilitate the alignment and verification of the data and AI requirements among the coalition members. The paper demonstrates the feasibility and effectiveness of the approach through a prototype implementation in the defense domain and a case study involving a multi-party coalition of the willing to detect a SA-8 anti-aircraft battery that in essence is a sensor-Data Fusion with different sensors on different weapon systems.

Conventional crowdfunding methods frequently involve intermediaries, lack transparency, encounter regulatory challenges, and are not highly secure. Instead, a blockchain-based agreement can be formed, carried out, and enforced between members without the assistance of a third party. To achieve this, creating smart contracts, with blockchain-compatible executable code, is crucial. Additionally, cryptocurrency can be used, for which crypto wallets can securely store private keys, giving users access, control, and ownership over their digital assets while also encouraging decentralization and interoperability. Crypto wallets protect users’ assets against cyber threats and unauthorized access by utilizing technologies like encryption, two-factor authentication, and multi-signature support to provide strong authentication and protection. Using a web3 platform like Thirdweb eliminates the need for an administrator by providing automated tools and infrastructure that streamline the creation, management, and deployment of decentralized applications. This study proposes the use of web3 technology to create a multi-user cross-platform blockchain-based crowdfunding DApp which employs Ethereum, smart contracts via solidity and crypto wallets for decentralized fundraising.
The emergence of blockchain technology spawned numerous experiments in alternative ownership and value creation. Uniting these was a singular thesis: That decentralized infrastructures could birth a new, user operated and owned Internet. This vision is what drives the otherwise inchoate collection of actors and activities called “Web3.” Web3’s infancy has been a wobbly one. Despite persistent claims to the contrary, many of its projects had echoes of practices that had emerged in different places and times – many of which were snuffed out by the relentless march of colonial capitalism. These same forces remain at play within Web3 and are most pronounced at its intersection with centralized and/or highly speculative financial services and products. There is a risk of building alternative’ digital spaces, modes of governance, and value systems, which are blind to history. In this chapter, I describe how my own blockchain alternative payment company offers an anthropology-based intervention, and how an anthropologist such as myself might guide these nascent projects away from building more technologically complex architectures of colonial capitalism, directing them instead toward alternatives which bulwark against the most pernicious harms of our time – from climate change to wealth inequality.
Although hardware trojans impose a relevant threat to the hardware security of RISC-V and Web3 applications, existing datasets have a limited set of examples, as the most famous hardware trojan dataset TrustHub has 106 different trojans. RISC-V specifically has study cases of three and four different hardware trojans, and no research was found regarding Web3 hardware trojans in modules such as a hardware wallet. This research presents a dataset of 290 Verilog examples generated with ChatGPT-4 Large Language Model (LLM) based on 29 golden models and the TrustHub taxonomy. It is expected that this dataset supports future research endeavors regarding defense mechanisms against hardware trojans in RISC-V, hardware wallet, and hardware Proof of Work (PoW) miner.

INTRODUCCIÓN: Los objetivos del desarrollo sostenible nos invita a cuidar el planeta y asegurar la prosperidad para todos. Frente a los cambiantes patrones de producción y consumo en torno al agua, energía y alimentos, resulta de gran interés estudiar la disponibilidad alimentaria, con el fin de implementar acciones que lleven a garantizar las necesidades de la población, permitiendo el desarrollo sustentable sin comprometer las generaciones futuras1,2. El objetivo del trabajo fue determinar la proporción de alimentos de origen vegetal (AOV) en relación al suministro total de energía para Argentina, Chile y Uruguay e inspeccionar su evolución en los últimos 60 años. MATERIAL Y MÉTODOS: estudio descriptivo, longitudinal. La proporción de AOV en la disponibilidad total de energía se consideró como el suministro de energía (kcal/persona/día) de los siguientes grupos de alimentos: cereales, tubérculos, legumbres, frutas, verduras, aceites, semillas, frutas secas y azúcar (excepto miel). Dicha información se extrajo de las Hojas de Balance de Alimentos (HBA), instrumento diseñado y elaborado por la Organización de las Naciones Unidas, para la Agricultura y la Alimentación (FAO), a partir de información estadística confiable disponible desde su sitio web3. Se consideró el período de 1961, 1990 y 2020 de las HBA para Argentina, Chile y Uruguay. Se tomaron estos años como referencia por la existencia de información proveniente de estos años y tomando ciclos de 30 años para evaluar posibles cambios en la disponibilidad alimentaria. CONSIDERACIONES ÉTICAS: los datos fueron extraídos de fuentes secundarias, todas las bases de datos son de dominio público y no requiere evaluación de comité de ética. RESULTADOS: El suministro de energía promedio durante el 2020 en los tres países fue 3232 ±95,1 Kcal/persona/día. En relación a la proporción de energía proveniente de AOV, fue mayor en Chile y Uruguay (68%), mientras que Argentina presentó un porcentaje menor (65,1%). El grupo de los cereales fue el que aportó la mayor cantidad de energía de AOV. La contribución de AOV a la energía total, aumentó en Uruguay y en Argentina, 14,5% y 2,8% respectivamente y disminuyó en Chile 9,6% entre 1961 y 2020. CONCLUSIONES: Si bien se evidenciaría algún incremento de disponibilidad de AOV principalmente en Uruguay, se requiere continuar trabajando en nuevas estrategias que garanticen la seguridad alimentaria y nutricional y permitan la conservación de recursos naturales.
Abstract This paper explores the influence of financialization in the post-2008 credit crisis, which led to a general mistrust in financial institutions and states. Simultaneously, Web3 and digital finance emerged as a way to navigate this problematic state of affairs, and many individuals were drawn to the agency of machines, code, and algorithms in making a deviation from austerity toward some form of liberation. Taking the form of an oracle reading, this paper uses the “Gambler” archetype to explore the subjective movement of those who engage with digital finance as a strategy to face the generalized climate of austerity and to claim their share of the economy, now that work has ceased to be a lifetime calling.
Abstract A Web3 lifeworld consists of an imaginary and a shared commons. A Web3 imaginary is shown to include most, if not all, of the following: (i) the stated goal or purpose of the community, (ii) the behavioral norms, (iii) the lore or history, and (iv) what is opposed. A typical Web3 commons is shown to involve three elements: hash (technical), bash (social) and cash (finance). When changes come in Web3, the response is enacted using an available lever from the hash, bash, cash model of decentralized organization, but the response must not be in friction with the community’s imaginary, or it will most likely grind to a halt. Effective response to change becomes part of the Web3 lifeworld’s toolkit.
Abstract Like an online carnival, Web3 aims to turn the internet’s social order upside down. Unlike a carnival, Web3 wants to be more than a weeklong party and morph into a legitimate substitute for the internet’s status quo. Web3’s secret sauce for upheaval is decentralized, permissionless technologies, in particular blockchain technologies. In this exploratory paper, we draw on the concept of institutional isomorphism to muse about Web3’s future and to highlight the inherent tension between striving to be different from Web2 yet wanting to become more legitimate. We argue that technical merits are hardly enough to realize Web3’s high aspirations. Regulatory pressures, rampant uncertainty, and the professional norms of Web3 participants drive the space to adopt many of the organizational structures and practices that it aims to displace. To maintain divergence from Web2, despite isomorphic pressures, we suggest that it is important to increase the overall diversity of people in Web3, to double down on the value of decentralization, and to reaffirm Web3’s commitment to creatively re-imagine various institutional arrangements.
Today the term Web3 (as distinct from Web 3.0) exists as a challenger to name the overall space variously known as cryptocurrency, Crypto or blockchain. It has an especial appeal to the post-2021 generation swept in under a wave of innovation in blockchain primitives. These primitives – Decentralised Autonomous Organisations (DAOs), Decentralised Finance (DeFi) and Non-Fungible Tokens (NFTs) – captured the imaginations of a new kind of user, one not necessarily plugged into the cypherpunk or crypto-anarchist ideals of Bitcoin. The term appears to partially reflect a desire to move beyond Bitcoin’s strictly monetary focus. The targets for blockchain decentralisation increasingly became the tech giants of Web 2.0, whose reputation had plummeted in this era.
Abstract Web3 reflects and instantiates the “ludic turn” of the last few decades, where identity is increasingly forged through play and games rather than through work. The ludic is especially evident in the Bitcoin ecosystem, where the elements of the carnivalesque – play, anarchy, dissimulation, vulgar language, and excessive consumption – are pervasive. These elements may also be divined in Web3, though they are less ubiquitous, which suggests that Web3 is perhaps best seen as a gentrified carnival.
