WPA2 is the most used wireless communication protocol in the world (2023). It first appeared in 2006, and now several vulnerabilities have been identified. To use WPA2-EAP or WPA3 (2018), which were released to compensate for the vulnerabilities of WPA2, additional equipment upgrades are required for STA (station) and AP (access point, router), which are connecting devices. We are currently living in the Web3 era. In the future society, people will have more than one NFT each. It is possible to improve the security of WPA2 by using this as an authentication means. In this paper, see the principles of WPA2 crack tools that are currently used today and suggest a way to defend against them using NFT. An experiment was carried out on the security of WPA2, which is widely used in SOHO environments, using only SBC (Single Board Computer) and NFT without expensive routers or additional authentication means. Hacking time, Internet connection delay time, download speed, etc. were compared on various PCs. In conclusion, this proposal demonstrated that representative WPA2 cracking tools can be defended without performance degradation compared to existing WPA2.
With the advent of the Web3.0 era, virtual assets have gained prominence in individuals’ asset portfolios, making Non-Fungible Tokens (NFTs) increasingly significant within the financial trading landscape. To address the issue of multicollinearity in regression analysis, this paper employs Principal Component Analysis (PCA) to perform dimensionality reduction on five correlated foundational sectors. Moreover, to enhance the accuracy and reliability of predictive outcomes, the study combines the Long Short-Term Memory (LSTM) model with the Autoregressive Moving Average-Generalized Autoregressive Conditional Heteroskedasticity (ARMA-GARCH) model. Through the application of these methods and practical implementation, the study forecasts the NFT index of the Hong Kong stock market for the next 30 days. This forecasting of return volatility contributes vital insights for investment decision-making. The research complements and offers application recommendations in financial innovation, deepening, and regulation. By devising novel products and tools to meet investor demands, providing risk management and investment opportunities, the model’s predictive outcomes can be utilized in regulatory and risk management strategies within the national financial trading market. This study provides regulatory guidance, policy formulation insights, and envisions further refinements of the research methodology by integrating information shock effects.
The rise of Web 3.0, which is based on independent technologies like blockchain and smart contracts, marks a big change in the financial technology field. This research looks at all the different ways that Web 3.0 can be used in FinTech by looking at real-life examples from Ethereum, Betterment, Wealthfront, DeversiFi, Synthetix, Kyber Network, and Curve Finance. By combining ideas from McKinsey's research, the study shows that Web3 lending sites are growing quickly. In 2021 alone, they gave out over $200 billion in loans. The study shows how Ethereum can be used for smart contracts, how Betterment and Wealthfront's robo-advisory services use AI and machine learning, how DeversiFi's decentralized exchange handles privacy issues, how Synthetix creates on-chain digital assets, how Kyber Network's blockchain-based liquidity protocol is put into use, and how Curve Finance's decentralized platform handles stablecoin transactions. Although there has been success, integrating these technologies is still very hard. The main problems are unclear regulations and technical issues with security, scalability, and interoperability. The final success of Web 3.0 in FinTech will depend on how well these problems are solved, which will help find a good balance between fast technological progress and strong risk management.
<p>In order for tokenized asset networks to be accountable as Web3 marketplaces for token-related transactions, identity verification must be conducted by gateways into those token networks. This includes the identity validation and legal status verification of the originators and beneficiaries, the gateway owners/operators, and other relevant service providers. The classic identity provider model could be enhanced to support anti-money laundering regulations, notably the Travel Rule. A privacy-preserving IdP model in combination with a legal service provider is explored where the IdP becomes the issuer of a blinded attestation regarding the user attribute, and where the legal representative with attorney-client privilege becomes the first point of contact for requests for the disclosure of the blinded attestations.</p>
Web3, the next generation of the Internet, represents a decentralized and democratized web. Although it has garnered significant public interest and found numerous real-world applications, there is a limited understanding of people's perceptions and experiences with Web3. In this study, we conducted an empirical study to investigate the categories of Web3 applications and their popularity, as well as the potential challenges and opportunities within this emerging landscape. Our research was carried out in two phases. In the first phase, we analyzed 200 popular Web3 projects associated with 10 leading Web3 venture capital firms. In the second phase, we collected and examined code-related data from GitHub and market-related data from blockchain browsers (e.g., Etherscan) for these projects. Our analysis revealed that the Web3 ecosystem can be categorized into two groups, i.e., Web3 infrastructure and Web3 applications, with each consisting of several subcategories or subdomains. We also gained insights into the popularity of these Web3 projects at both the code and market levels and pointed out the challenges in the Web3 ecosystem at the system, developer, and user levels, as well as the opportunities it presents. Our findings contribute to a better understanding of Web3 for researchers and developers, which in turn promotes further exploration and advancement in this innovative field.
The promise of a fully decentralized web is too big to ignore. The bridging of Web2 and Web3 infrastructure is crucial for realizing this decentralized future. However, the current computational and storage demands in blockchain systems often result in challenges for users, leading to reliance on centralized endpoint API services in Web3 application designs. This dependence raises concerns about privacy, availability, and security. This doctoral study aims to enhance the accessibility and decentralization of blockchains, especially by facilitating the participation of resource-constrained devices such as smartphones and browsers. The goal is to facilitate the widespread adoption of decentralized systems that are secure, reliable, and scalable.
The Non Fungible Tokens are assets that have exploded wisely in recent years. One area where NFTs are yet to impact is in pet's life. Therefore, an NFT Marketplace for pets can be created so that pets can be embraced. This marketplace allows customers to list, sell, and buy NFTs. Marketplace will contain images or videos of pets as NFTs, that will be uploaded by the owner of the pet. There will also be a listing amount that can be mentioned by the owner and also it will have a minimum value of 0.01ETH. This value can be increased by the owner according to his/her interest. There will be several benefits to using NFTs as pets will get a secure environment and health care. The user can register to the marketplace with his Web3 wallet. This paper explains that these NFTs can be used to store and track important information about pets, such as their health records, and ownership. Owners or users will be able to develop their interest in the marketplace as it provides a gamified view. This marketplace will help in maintaining transparency and help owners to get informed about their pet's related vital information.
The ROSA Journal focuses on three primary areas: (1) the examination of blockchain and Web3 research within societal contexts; (2) the application of quantitative methodologies in the fields of the humanities and social sciences; and (3) the provision of research-driven reviews of current social, political, and economic issues. We support the promotion of interdisciplinary collaboration between individuals from the natural sciences and the social sciences in order to produce a body of scientific knowledge that exceeds the capacity of a conventional academic journal.
Blockchain technology contributes to achieving the Sustainable Development Goals. Education for sustainable development (ESD) is UNESCO’s education sector response to the urgent and dramatic challenges the planet faces. The traditional way of donating money to charitable causes, such as education, has been through centralized methods and organizations that lack transparency, and donors often do not have a clear understanding of how their contributions are being utilized. Blockchain technology, particularly, platforms like Ethereum and Polygon, has the potential to address the issues associated with traditional donation systems. This paper proposes a decentralized web3 application that utilizes blockchain technology to enhance transparency and efficiency in educational donations in the context of sustainable development. The platform leverages decentralized protocols and smart contracts to ensure secure and transparent transactions, enabling donors to track the utilization of their contributions and ensuring their funds reach their intended beneficiaries. This paper discusses the design and implementation of the platform, highlighting its features and potential for transforming the landscape of charitable donations. This software application can be used in education, and a demo plus some scenarios/work cases are presented/analyzed. The main results and contributions open other future research directions for not only authors.
Non-Fungible Token (NFT) is a carrier of unique identity as a virtual currency. Its indivisible, unique, and verifiable characteristics can truly reflect personal assets and virtual assets to a certain extent. It is widely applied by users in art, games, collectibles and other areas. NFT is stored on the blockchain. The user's digital signature is embedded into the NFT record, which is distributed through a smart contract and verified by the blockchain consensus mechanism, thus solving the problem of identity confirmation in digital asset transactions. This paper makes a review of the main processes and key technologies in NFT applications. First, it introduces the life of NFT: minting, distribution, storage and circulation. Then, the key technologies of NFT are explained, including the blockchain smart contracts and consensus mechanisms in NFT distribution and transaction, the token standards that the minting and transaction process of NFT needs to use, and the important role of NFT in the field of web3. Finally, through the evaluation system of NFT, the problems existing in the current NFT applications and the future research direction are drawn out.
Web3 applications based on blockchains regularly need access to randomness that is unbiased, unpredictable, and publicly verifiable. For Web3 gaming applications, this becomes a crucial selling point to attract more users by providing credibility to the "random reward" distribution feature. A verifiable random function (VRF) protocol satisfies these requirements naturally, and there is a tremendous rise in the use of VRF services. As most blockchains cannot maintain the secret keys required for VRFs, Web3 applications interact with external VRF services via a smart contract where a VRF output is exchanged for a fee. While this smart contract-based plain-text exchange offers the much-needed public verifiability immediately, it severely limits the way the requester can employ the VRF service: the requests cannot be made in advance, and the output cannot be reused. This introduces significant latency and monetary overhead.

We present ColorFloat, a family of O(1) space complexity algorithms that solve the problem of attributing (coloring) fungible tokens to the entity that minted them (minter). Tagging fungible tokens with metadata is not a new problem and was first formalized in the Colored Coins protocol. In certain contexts, practical solutions to this challenge have been implemented and deployed such as NFT. We define the fungible token coloring problem, one specific aspect of the Colored Coins problem, to be the problem of retaining fungible characteristics of the underlying token while accurately tracking the attribution of fungible tokens to their respective minters. Fungible token coloring has a wide range of Web3 applications. One application which we highlight in this paper is the onchain yield-sharing collateral-based stablecoin.
The advent of Web3 has ushered in a new era of decentralized digital economy, promising a shift from centralized authority to distributed, peer-to-peer interactions. However, the underlying infrastructure of this decentralized ecosystem often relies on centralized cloud providers, creating a paradoxical concentration of value and power. This paper investigates the mechanics of value accrual and extraction within the Web3 ecosystem, focusing on the roles and revenues of centralized clouds. Through an analysis of publicly available material, we elucidate the financial implications of cloud services in purportedly decentralized contexts. We further explore the individual's perspective of value creation and accumulation, examining the interplay between user participation and centralized monetization strategies. Key findings indicate that while blockchain technology has the potential to significantly reduce infrastructure costs for financial services, the current Web3 landscape is marked by a substantial reliance on cloud providers for hosting, scalability, and performance.
Decentralized physical infrastructure network (DePIN) is an emerging research topic in Web3 and blockchain. By combining blockchain, IoT and tokenomics, DePINs are expected to disrupt existing IoT business models and enable Web3 communities to build innovative, machine-driven and decentralized IoT networks and applications. Due to the characteristics of DePINs such as the large number of smart devices and network scale as well as the interactions with blockchain, scalability remains to be one of the key challenges. In this position paper, we outline the core ideas and components for building a rollup-centric scalable architecture for DePINs. The proposed architecture takes a modular design approach and leverages off-chain computing and zero-knowledge proofs to address the scalability challenge. This work is expected to highlight the importance of this new research direction and shed some light on potential solutions.
Blockchains have inspired imaginaries of a new iteration of the internet, hailed as Web3, where the power of centralized platform companies would be limited and the ownership of personal data and content could be retained by their individual owners and creators. Web3 is expected to facilitate the emergence of novel protocols and platforms that enable decentralized coordination of data and digital assets. This article examines critically the experiences and imaginaries of creators working on two blockchain-based video-sharing platforms: Theta.tv and Odysee. Building on the studies of creator culture and institutionalist blockchain economics and based on open-ended interviews with the early adopters of these platforms, the paper investigates how the creators experience these decentralized social media applications in terms of their processes of governance, community creation, and career development. We show how the affordances of blockchains and creator expectations can result in further convergence of community management and career-building functions potentially benefiting creators. We also show that the new wave of decentralization, against optimistic blockchain visions, has not yet led to the distributed ‘ownership’ of social media networks. Rather, while blockchains seem to have increased creator autonomy and added career opportunities, novel forms of platform governance and power have also introduced new perceptions of precarity among creators.

The importance of developing software that keeps pace with Web3 technologies is crucial in fostering discussions about their utilization in the current scientific landscape. Within this context, this research aims to present the development of a "criptogame" that utilizes blockchain technology to incorporate NFTs (Non-Fungible Tokens) into its mechanics. The text addresses fundamental concepts of Web3, making references to relevant literature. Subsequently, the development process is described, including specific methodologies and models. The obtained results consist of a puzzle game that incorporates NFTs as playable characters and enables the transfer of these assets between digital wallets.
Web3 systems expose a fundamentally different security landscape from centralized platforms, characterized by composability, pseudonymous identities, decentralized governance, and rapidly evolving attack strategies that span social, application, and protocol layers. Existing security mechanisms, such as static smart contract analysis, blacklist-based phishing detection, and network-level mitigation, operate in isolation and assume fixed threat models, limiting their effectiveness against adaptive, cross-layer adversaries. This position paper argues that securing Web3 requires a shift from static, tool-centric defenses to learning-driven security primitives capable of continuous reasoning, adaptation, and actuation. We introduce AI-powered smart certificates as a new security abstraction: programmable, continuously updated trust artifacts that integrate on-chain verifiability with off-chain machine learning signals derived from user behavior, transaction dynamics, and social context. Unlike traditional certificates or audits, these certificates maintain state, learn under distribution shift, and support automated policy enforcement and revocation in response to evolving threats. We argue that existing paradigms, formal verification, threat modeling, and isolated anomaly detection, are structurally limited in capturing the non-stationary and socio-technical nature of Web3 attacks. We outline an architecture in which AI-powered smart certificates serve as cross-layer sentinels that coordinate heterogeneous security signals in real time, and position smart certificates as a research direction, raising questions around learning under partial observability, adversarial adaptation, and trustworthy ML deployment in decentralized systems.
Decentralized Finance (DeFi) is a prominent application of smart contracts, representing a novel financial paradigm in contrast to centralized finance. While DeFi applications are rapidly emerging on mainstream blockchain platforms, their quality varies greatly, presenting numerous challenges, particularly in terms of their governance mechanisms. In this paper, we present a comprehensive study of governance issues in DeFi applications. Initially, we collected 3,165 academic papers and numerous industry reports. After thorough screening, we selected 44 academic papers and 11 industry reports for detailed analysis. Drawing upon insights from industry reports and academic research articles, we develop a taxonomy to categorize these governance issues. We collect and build a dataset of 4,446 audit reports from seventeen Web3 security companies, categorizing their governance issues according to our constructed taxonomy. We conducted a thorough analysis of governance issues and identified vulnerabilities in the governance design and implementation, e.g., voting sybil attack and proposal front-running. Our statistical analysis indicates that a significant portion (35.48%) of governance-related issues is classified as severe. Within these, ownership-related problems constitute the largest share (65.38%). Despite DeFi governance being essential for the long-term success of DeFi projects, our data shows that both auditors and development teams have not fully grasped its significance. Based on audit reports, we also analyzed common vulnerabilities and issues in the governance domain. Our research identifies two primary categories of DeFi governance issues: technology-centric and human-centric. Technology-centric issues can be addressed through technology updates and iterations, whereas human-centric issues are influenced not only by the development team's technical skills but also by their understanding of DeFi governance. Data analysis reveals that design and implementation issues are frequently overlooked; although not directly associated with vulnerabilities, these issues can impact the equitable distribution of project benefits. Furthermore, our analysis of 104 projects’ tokenomics configurations, including 15 collected from DeFi platforms, uncovered 27 inconsistent configurations, with only two projects exhibiting no issues. This suggests that such issues are relatively common. We therefore advise project teams to ensure consistency between their tokenomics design and the actual code. Our study culminates in providing several key practical implications for various DeFi stakeholders, including developers, users, researchers, and regulators, aiming to deepen the understanding of DeFi governance issues and contribute to the robust growth of DeFi systems.
Non-Fungible Tokens (NFTs) have emerged as the most representative application of blockchain technology in recent years, fostering the development of the Web3. Nonetheless, while the interest in NFTs rapidly boomed, creating unprecedented fervour in traders and creators, the demand for highly representative and up-to-date data to shed light on such an intriguing yet complex domain mostly remained unmet. To pursue this objective, we introduce a large collection of NFT transactions and associated metadata that correspond to trading operations between 2021 and 2023. Our developed dataset is the most extensive and representative in the NFT landscape to date, as it contains more than 70 M transactions performed by more than 6 M users across 36.3 M NFTs and 281 K collections. Moreover, this dataset boasts a wealth of metadata, including encoded textual descriptions and multimedia content, thus being suitable for a plethora of tasks relevant to database systems, AI, data science, Web and network science fields. This dataset represents a unique resource for researchers and industry practitioners to delve into the inner workings of NFTs through a multitude of perspectives, paving the way for unprecedented opportunities across multiple research fields.
Web3 and AI have been among the most discussed fields over the recent years, with substantial hype surrounding each field's potential to transform the world as we know it. However, as the hype settles, it's evident that neither AI nor Web3 can address all challenges independently. Consequently, the intersection of AI and Web3 is gaining increased attention, emerging as a new field with the potential to address the limitations of each. In this article, we will focus on the integration of web3 and the AI marketplace, where AI services and products can be provided in a decentralized manner (DeAI). A comprehensive review is provided by summarizing the opportunities and challenges on this topic. Additionally, we offer analyses and solutions to address these challenges. We've developed a framework that lets users pay with any kind of cryptocurrency to get AI services. Additionally, they can also enjoy AI services for free on our platform by simply locking up their assets temporarily in the protocol. This unique approach is a first in the industry. Before this, offering free AI services in the web3 community wasn't possible. Our solution opens up exciting opportunities for the AI marketplace in the web3 space to grow and be widely adopted.
On 8 September 2022, the American artist Frank Stella launched a series of twenty-two digital art works minted as Non-Fungible Tokens (NFTs) in collaboration with Arsnl, the in-house platform by the Artist Rights Society (ARS). Titled Geometries, each “package,” included the NFT that would affirm ownership and the corresponding geometric model designed by Stella in JPG (image), MP4 (video), SLS (3D printing), GLB (virtual reality and model manipulation), and USDZ (augmented reality). This range of digital formats alludes to two of Stella’s innovations in this space: the license to remix and manipulate his models, and the ability to 3D print Geometries at any color, scale, and material. Taking Stella’s foray into the NFT-space as a starting point, my article focuses on an emergent trend by artists engaging with Web3: the effort to bridge the physical and the digital by giving tangible form to NFT artworks and what this suggests for the future of digital materiality. The paper at its core seeks to examine the relationship between the physical referents to NFTs at the very moment when new media returns to historical forms.

Maritime transportation plays a critical role for many Arab countries and their food security and has evolved into a complex system that involves a plethora of supply chain stakeholders spread around the globe. This inherent complexity brings huge security challenges, including cargo loss and high burdens in cargo document inspection. The emerging blockchain technology provides a promising tool to build a unified maritime cargo tracking system critical for cargo security. This is because blockchains are a tamper-proof distributed ledger technology that can store and track data in a secure and transparent manner. Using the State of Qatar as a case study, this research introduces the Global Maritime Ledger (GM-Ledger), which will aid authorities in verifying, signing and transacting food certificates in an efficient manner. The methodology of this research includes reviewing past publications, identifying the requirements of various players in the Qatari food import-export industry and then creating a smart contract framework that will efficiently manage the work with necessary human intervention as and when required. The result of this work is the formation of a solid framework that can be employed in future works. This work realized that employing web3 solutions for the food import sector is highly viable and that with the right social, economic and policy reforms, it is possible to transform the entire food system to bear healthy transparency and power balance in global supply chains. In conclusion, this study argues that BCT has the ability to assist the government and other players to minimize fraud and maximize food supply chain stakeholder participation.
