ABSTRACT Forgery of academic and professional certificates remains a major concern across institutions. Traditional centralized systems are prone to manipulation and single points of failure. This work presents a blockchain-based certificate issuance and verification platform developed using Spring Boot and the Ethereum Sepolia test network. The system supports multiple organizations where issuers register and are approved by an administrator before generating certificates. Each certificate is assigned a unique identifier, and a SHA-256 hash of its data is stored on the blockchain through smart contracts. The platform also automates PDF certificate creation with embedded QR codes and sends them via email. Additional features include bulk certificate generation, revocation support, and public verification without requiring a blockchain wallet. Experimental observations indicate an average issuance time of around 4 seconds and verification within 1.5 seconds. Keywords: Blockchain, Ethereum, Smart Contracts, SHA-256, Certificate Verification, Spring Boot, Web3j, PDF Automation

Among the most influential technologies that predetermine the current digital society, artificial intelligence (AI) and blockchain have emerged as fast as the digitalization of technologies. This review examines the conceptual and practical implications and applications of AI and blockchain with particular attention to how the two can be used in the framework of digital governance, cybersecurity, and socio-cultural change. The analysis synthesizes existing literature to explore how AI enhances data processing, predictive analytics, and automated decision-making, while blockchain strengthens transparency, decentralization, and data integrity in digital systems. Their integration is shown to support more efficient governance frameworks, improved policy decision-making, secure digital infrastructures, and reliable identity management. At the same time, the review highlights broader societal impacts, including changes in digital trust, ownership structures, and creative and media industries. Despite these opportunities, several challenges remain, including governance fragmentation, ethical concerns, privacy risks, and limitations related to interoperability and institutional readiness. New research directions are also outlined in the form of trustworthy and explainable AI, sustainable technological infrastructures, and the adoption of AI and blockchain systems of Web3 and decentralized digital ecosystems. Altogether, AI and blockchain convergence is an important change in the structure of the digital space, and it will need harmonized governance structures and responsible innovation to establish safe, transparent and inclusive digital societies.
Abstract This study presents a structured dataset of blockchain-registered artificial intelligence agents under the ERC-8004 standard on Ethereum. The dataset integrates on-chain identity records, minting transactions, transfer events, reputation summaries, and individual feedback records, together with resolved off-chain metadata where available. Data were collected from Ethereum mainnet using Web3 RPC queries and processed into tabular form to enable reproducible analysis. The dataset covers 10,000 agents within a defined block range and includes both event-level records and aggregated summaries. It enables empirical research on agent identity formation, reputation systems, service exposure, and early-stage decentralized AI ecosystems. This resource supports studies in blockchain analytics, decentralized trust infrastructure, and the emerging agentic economy.

The increasing reliance on digital systems in law enforcement has emphasized the need for secure, transparent, and reliable mechanisms to manage crime evidence. In existing systems, evidence management is typically handled through centralized databases and manual record-keeping, where crime reports, officer details, and evidentiary materials are stored in a single controlled environment. This approach introduces critical challenges such as data tampering, unauthorized access, loss of sensitive information, and lack of transparency, which can weaken trust and complicate legal proceedings. Furthermore, storing evidence in physical formats or unsecured digital systems makes it difficult to ensure authenticity and maintain a proper Chain of Custody (CoC). These limitations highlight the necessity for a system that ensures data integrity, traceability, and secure verification. To overcome these issues, the proposed framework adopts a decentralized architecture using Blockchain technology and Smart Contracts to provide immutability, transparency, and enhanced security of evidence records. The system leverages Ethereum for decentralized data storage, Web3 for enabling interaction between the application and the blockchain network, and Django as the web framework for managing the user interface, file handling, and administrative functionalities. Authorized officers can securely upload, access, and manage evidence, while administrators can monitor and verify transactions in real time. Each evidence record is assigned a unique identifier and permanently stored on the blockchain, preventing unauthorized modification and ensuring a verifiable audit trail. Although the system does not utilize Machine Learning (ML) or Deep Learning (DL), it effectively employs smart contracts-based automation for secure evidence tracking, thereby improving accountability, legal reliability, and operational efficiency.

The evolution of blockchain technology has introduced innovative approaches for managing digital assets and transforming fundraising models through Non-Fungible Tokens (NFTs). However, many existing charity platforms continue to operate on centralized systems that restrict transparency, limit accountability, and fail to provide donors with verifiable proof of their contributions. In such systems, donors often have minimal visibility into fund utilization, and there is no direct linkage between their contributions and any traceable digital asset. Moreover, traditional charity and auction mechanisms rely heavily on intermediaries for transaction validation, data management, and operational control, making them susceptible to data manipulation, reduced auditability, and diminished user trust, while also lacking mechanisms to encourage active participation. To address these limitations, this research proposes a decentralized charity auction framework that integrates Blockchain technology with NFTs to ensure secure, transparent, and verifiable transactions. The system is developed using the Django Web Framework and leverages Web3 Technology along with Smart Contracts to automate and manage auction processes. Each auction item is uniquely tokenized as an NFT, guaranteeing authenticity and non-replicability. Users can register as donors or auction organizers, create NFTbased auctions, and participate through bidding or direct contributions. All transactions are permanently recorded on the blockchain, and NFT ownership is automatically transferred to the highest bidder or contributor, serving as a verifiable digital proof of participation. By removing intermediaries and ensuring immutable record-keeping, the system enhances trust, strengthens security, and introduces an incentive-driven participation model, thereby improving transparency, accountability, and efficiency in modern charity and fundraising ecosystems.
Abstract Web3 infrastructure has demonstrated that decentralized coordination is technically feasible. Yet the dominant governance model — token-weighted voting — produces structural concentration of decision-making authority over time, and has not proved well-suited to real-world economic coordination. This paper argues that the missing element is constitutional ownership geometry: a structural arrangement of bounded roles and non-dilutable stakeholder balance that persists as participation evolves. We introduce the Vessel Compartment System (VCS), developed within the Mycelia Inclusive Networks (MIN) framework, as one such approach. VCS distributes governance authority across fixed ownership compartments representing distinct stakeholder roles — community participants, operators, capital providers, and ecosystem partners — each non-dilutable relative to the others. Participants within compartments may change; the balance among compartments does not. Web3 infrastructure provides the enforcement and portability layer this model requires: smart contracts encode compartment boundaries, tokenized roles enable exit without requiring dissolution of institutional structure, and composable systems support cross-vessel coordination. Together, these features allow governance to remain internally stable while evolving externally through participant migration across structurally stable governance units. The paper situates VCS within established governance theory, contrasts it with token-weighted and procedural governance models, and examines its implications for real-world economic coordination and Web3 system design. Keywords: Web3 governance, token-weighted voting, decentralized autonomous organizations, ownership geometry, Vessel Compartment System, constitutional governance, exit-driven evolution, real-world economic coordination, multi-stakeholder governance
This research presents a blockchain-enabled freelancing platform that integrates smart contract-based escrow, decentralized identity, and intelligent freelancer matching to promote trust, transparency, and automation in digital labor markets. The system uses an Ethereum-compatible smart contract called Freelance Escrow, which manages the funding of projects securely, restricts interactions between employers and freelancers to a few specific roles, and automates the release of payments based on the verifiable completion of work. A Python-based blockchain interface developed using Web3.py is used to deploy contracts, sign transactions, and retrieve the current states, while a Streamlit front end provides authentication for user, project, and wallet operations. The platform includes a TF-IDF similarity model that matches freelancers to projects based on relevant skills and semantic similarity, as well as a structured database using SQLite, in which all users, profiles, and project metadata are stored. Comprehensive analysis reveals that the application has strengths in automation, transparency, and enforcement of workflow, while addressing privacy concerns around private key handling, file path inconsistencies, and Web3 library compatibility. The research demonstrates a working end-to-end architecture for decentralized freelance contracting and establishes a foundation for building further secure, scalable, and trust-preserving digital marketplaces.

The rapid expansion of blockchain infrastructures, Web3 architectures, and immersive metaverse environments has reignited calls for a Universal Code of Digital Ethics. International organizations, technology leaders, and multilateral forums increasingly advocate for global standards capable of guiding decentralized innovation toward inclusion, transparency, and social good. Yet the normative ambition of universality confronts a structural contradiction: digital access, connectivity quality, and technological literacy remain profoundly unequal across the Global South.Ethical frameworks for Web3 and the metaverse often presuppose a baseline of connectivity, computational capacity, and institutional stability that large segments of humanity do not possess. The COVID-19 pandemic amplified these asymmetries, accelerating digital transformation in high-income countries while deepening infrastructural gaps elsewhere. Concurrently, geopolitical tensions and emerging techno-nationalist strategies have repoliticized digital infrastructure as a domain of strategic competition rather than global solidarity.This Opinion article argues that any claim to a "universal" digital ethics framework is normatively fragile unless it incorporates a structural critique of global capitalism, technological acceleration, and asymmetrical power. Drawing on critical theory-particularly Herbert Marcuse's concept of the "one-dimensional man"-as well as Marxian analyses of technology and capital, I contend that ethical discourse risks becoming ideologically functional to market expansion if it fails to address material inequalities in connectivity and digital capability (Marcuse, 1972;Marx, 2005;García Ramírez, 2021).proposals but also problematizes the concept of universality itself as a normative and political construct.Global ethics initiatives often frame digital transformation as inherently democratizing. Blockchain is described as decentralized, Web3 as user-empowering, and the metaverse as participatory. However, decentralization at the protocol level does not necessarily translate into equitable access at the societal level.In regions of the Global South, access to stable broadband remains limited, mobile data costs are disproportionate to income, and digital literacy gaps persist. Under such conditions, the ethical vocabulary of autonomy, self-sovereign identity, and tokenized participation becomes aspirational rather than operative.Marx's analysis of technology as a force embedded within relations of production remains instructive. Technology is not neutral; it is shaped by capital accumulation dynamics (Marx, 2005). Fumikazu (1983) similarly emphasized that technological evolution must be understood historically and politically. When applied to Web3 ecosystems, this suggests that blockchain infrastructures operate within global financial logics that may reproduce, rather than dissolve, structural dependency.Contemporary Science and Technology Studies (STS) and critical philosophy of technology further reinforce this perspective. Feenberg (1999) argues that technology is not merely instrumental but socially constructed and politically conditioned, shaped by dominant interests yet open to democratic transformation. Similarly, Yuk Hui (2020) challenges the presumed universality of technological rationality, proposing the concept of "technodiversity" to account for plural technological trajectories rooted in different cultural and cosmological traditions. These perspectives suggest that any ethical framework for digital technologies must recognize the multiplicity of socio-technical realities rather than assume a homogeneous global condition.Thus, a universal code of digital ethics risks functioning as what critical theory would describe as ideological abstraction-detached from the material preconditions required for ethical agency.Herbert Marcuse's One-Dimensional Man (1972) provides a compelling lens through which to interpret contemporary digital governance. Marcuse argued that advanced industrial societies generate a form of technological rationality that integrates dissent by absorbing it into the logic of efficiency and consumption.In the context of Web3 and the metaverse, ethical discourse may become one-dimensional when it focuses on procedural compliance (privacy standards, transparency metrics, algorithmic audits) while neglecting structural exclusion. The language of inclusion becomes embedded within market expansion strategies. As Daum (2018) argues, digital capitalism increasingly converts users into capital itself-data, attention, and participation become monetizable assets.From a constructivist perspective, technologies such as blockchain are not inherently emancipatory but acquire meaning through their social embedding (Bijker, 1995). This implies that ethical claims about decentralization and empowerment must be evaluated in relation to the socio-economic contexts in which these technologies are deployed. Without such contextualization, ethical discourse risks overstating the transformative potential of technological architectures. This dynamic is particularly visible when global institutions promote digital entrepreneurship and blockchain adoption in developing regions without parallel investments in public infrastructure, education, and regulatory sovereignty. The rhetoric of empowerment may conceal asymmetric dependency.Cañas Quirós (2023) emphasizes that ethics cannot be separated from political structures; morality detached from power analysis risks legitimizing unjust arrangements. In this sense, digital ethics frameworks must confront the political economy of connectivity rather than merely codify behavioral norms for technology developers.Digital governance is increasingly entangled with geopolitical competition. Infrastructure financing, cloud sovereignty, semiconductor supply chains, and cybersecurity alliances shape technological ecosystems. In this context, international organizations often advocate regulatory harmonization to "facilitate innovation" and "reduce market friction".While harmonization may lower barriers for cross-border digital services, it can simultaneously constrain policy autonomy in developing nations. Ethical frameworks that prioritize market efficiency risk subordinating universal connectivity goals to investor confidence and capital mobility.García Ramírez (2021) calls for a "Marx in the South," reinterpreting technology through the lens of rights, education, and structural inequality. From this perspective, Web3 adoption without universal broadband is analogous to building virtual property rights atop infrastructural scarcity. The promise of decentralized finance or immersive governance becomes utopian-or dystopian-when foundational digital rights remain unrealized.The acceleration principle of technological evolution -where innovation in wealthy nations compounds exponentially-renders access in peripheral regions inversely proportional to global advancement. Ethical frameworks that ignore this asymmetry may inadvertently normalize a tiered digital citizenship.The assumption that a single set of ethical principles can be universally applicable across diverse socio-cultural and technological contexts has been widely debated. From decolonial and pluralist perspectives, ethical frameworks are historically situated and epistemically conditioned (Escobar, 2018). What is considered "ethical" in one context may not translate directly into another, particularly when technological infrastructures, cultural values, and political systems differ significantly.In this sense, the concept of a Universal Code of Digital Ethics may be inherently paradoxical. Rather than a fixed and homogeneous set of principles, digital ethics may need to be understood as a plural and adaptive framework, capable of accommodating different technological ontologies and social priorities. This does not imply abandoning normative aspirations, but rather rethinking universality as negotiated, situated, and contingent.If a global digital ethics framework is to be normatively defensible-whether universal or plural-it must integrate structural and contextual dimensions:If universality is to be normatively defensible, digital ethics must integrate at least five structural components:If universality is to be normatively defensible, digital ethics must integrate at least five structural components:1.Material Preconditions Clause: Ethical standards should explicitly recognize connectivity, affordability, and digital literacy as prerequisites for meaningful participation.Political Economy Transparency: Frameworks must disclose how market incentives shape technological deployment.Geopolitical Reflexivity: Digital governance should account for power asymmetries between states and corporations.Public Infrastructure Commitment: Ethical guidelines must prioritize universal broadband as a public good, not merely a commercial opportunity.Critical Participation Mechanisms: Inclusion must extend beyond tokenized representation toward substantive decision-making capacity.5.6. Epistemic Pluralism: Ethical frameworks must recognize diverse knowledge systems, cultural values, and technological imaginaries, particularly from the Global South.Such principles align ethics with transformative social justice rather than technocratic governance.The aspiration to develop a Universal Code of Digital Ethics for Web3 and the metaverse is commendable. However, without structural critique, universality risks becoming rhetorical. Critical theory reminds us that technological systems embed power relations (Marcuse, 1972). Marxian perspectives reveal how capital shapes technological deployment (Marx, 2005). Contemporary analyses from the Global South highlight the need to situate ethics within historical and geopolitical realities (García Ramírez, 2021;Cañas Quirós, 2023). The ethical question is not merely how to regulate blockchain or ensure transparency in virtual worlds. It is whether digital transformation reproduces one-dimensional rationality-where market logic absorbs ethical discourse-or fosters multidimensional emancipation grounded in material equality.A truly global digital ethics must therefore begin not with code, but with conditions. Without universal connectivity and critical capacity, Web3 and the metaverse risk becoming architectures of selective participation. Ethics, to be universal, must first be infrastructural. Ethics, whether conceived as universal or plural, must first be infrastructural, contextual, and politically grounded.
The rapid collapse of decentralized game economies, often characterized by the \textit{death spiral,} remains the most formidable barrier to the mass adoption of Web3 gaming. This paper proposes that the sustainability of an open game economy is predicated on three necessary and sufficient conditions: Anti-Sybil Resilience, Anti-Capital Dominance, and Anti-Inflationary Saturation. The first section establishes a theoretical proof of these conditions, arguing that the absence of any single dimension leads to systemic failure. The second section explores the dialectical relationship between these dimensions, illustrating how unchecked automation and capital-driven monopolies accelerate asset hyperinflation. In the third section, we introduce the Identity-Bound Asset Integrity Model (IBAIM) as a comprehensive technical solution. IBAIM utilizes Zero-Knowledge (ZK) biometric hashing and Account Abstraction (AA) to anchor asset utility to unique human identities through a privacy-preserving and regulatory-compliant architecture. By exogenizing biometric verification to trusted local environments and utilizing Zero-Knowledge Proofs of Identity (zk-PoI), the model ensures absolute user privacy. Furthermore, by implementing an Asymmetric Utility Decay (AUD) engine-whereby assets suffer a vertical 50% utility cliff upon secondary transfer-and an entropy-driven thermodynamic degradation mechanism., the model successfully decouples financial speculation from in-game merit. Finally, we apply this framework to analyze prominent historical failures in the GameFi sector, demonstrating that their collapse was an inevitable consequence of violating these core economic constraints. Our findings suggest that trading a degree of asset liquidity for system integrity is the only viable path toward long-term economic viability in decentralized virtual worlds.

This study analyzes the influence of Digital Leadership, Digital Literacy, and Digital Competency on Innovative W This study examines the influence of Digital Leadership, Digital Literacy, and Digital Competency on Innovative Work Behavior (IWB) among Web3 remote workers in Surabaya City. The research is grounded in the transformation of remote work within the Web3 ecosystem, which presents innovation challenges due to limited spontaneous social interaction. This study addresses both a contextual gap, focusing on the underexplored population of Web3 workers, and a methodological gap by integrating three key digital factors into a single analytical framework. A quantitative approach was employed using purposive sampling, involving 70 Web3 remote workers in Surabaya. Data were analyzed using multiple linear regression with SPSS software. The results show that Digital Leadership (β = 0.330), Digital Literacy (β = 0.322), and Digital Competency (β = 0.301) have a positive and significant effect on Innovative Work Behavior (p < 0.05). Simultaneously, the variables significantly influence IWB (F = 45.646), with a coefficient of determination (R²) of 0.675, indicating that 67.5% of the variation in IWB is explained by the model. These findings confirm that the integration of digital leadership, strong digital literacy, and well-developed digital competency plays a critical role in enhancing innovative work behavior in Web3 remote work environments. The study contributes to the development of Upper Echelons Theory in the context of decentralized digital work and provides practical insights for organizations in designing effective digital talent strategies.

This study synthesizes Web3-based governance strategies in closed supply chains for electric vehicle batteries in Indonesia, focusing on reducing environmental impacts and improving resource efficiency. It includes a theoretical framework and case studies to address the overall issues in empirical validation and contextual adaptation. This paper aims to expand the governance framework, compare digital product passport implementations, identify incentive mechanisms including CSR integration, quantify regulatory models, and analyze practical case studies. An integrated analysis of multidisciplinary literature, using theoretical modeling, game theory, and empirical case studies, reveals that blockchain-based digital product passports improve transparency and lifecycle traceability but face challenges in large-scale implementation and data standardization. Incentive mechanisms based on game-theoretic frameworks and CSR promote resource efficiency, although empirical evidence in Indonesia remains limited and its social dimensions remain underexplored. A comparative regulatory analysis highlights the relevance of EU policies as a benchmark while also highlighting regulatory gaps and enforcement challenges in Indonesia. The case studies demonstrate the feasibility of Web3 technologies in improving environmental outcomes and operational efficiency, but scalability and stakeholder coordination require further investigation. These findings highlight the need for an integrated, multi-stakeholder governance model that bridges theoretical innovation with practical implementation in Indonesia's unique socio-regulatory context. This study informs future research and policy development to optimize sustainable battery supply chains through digital governance and circular-economy principles.
Academic credential fraud poses a critical challenge to Indonesian higher education, with approximately 30% of job applicants providing false academic qualifications while conventional verification processes require 2–4 weeks with significant administrative costs. This research addresses the gap where 77% of blockchain education research remains conceptual by proposing and evaluating a four-layer blockchain system architecture for academic diploma authentication. Using Design Science Research Methodology (DSRM), the study designs and implements a layered architecture comprising a Presentation Layer (React 18.2.0 with client-side SHA-256 hashing), Application Layer (Node.js 18.20.8 with Web3.js), Data Layer (PostgreSQL 14.5 for off-chain metadata), and Blockchain Layer (DiplomaValidator smart contract in Solidity 0.8.19 on Ganache 2.7.1). The architectural design enforces separation of concerns, enabling tamper-evident credential storage through immutable on-chain hash registration and trustless public verification through zero-gas view functions. Comprehensive evaluation through 38 functional tests, performance benchmarking, security auditing, and integration testing demonstrates 100% pass rate across all categories. Performance metrics show registration in 15.23 ms (240,082 gas units) and verification in 9.47 ms at zero gas cost, achieving 51.81 TPS throughput. Security audit yields 95/100 with zero high or medium vulnerabilities. The primary contribution of this research is a formally documented four-layer blockchain architecture for academic credential authentication validated through DSRM providing a replicable architectural model and quantified performance baselines for the Computer Science community and Indonesian higher education institutions considering blockchain adoption
This paper examines Web3 ecosystems not merely as markets for digital assets, but as networked social spaces where economic transactions give rise to enduring social ties, shared narratives, and collective identities. Leveraging large-scale data mining of fused on-chain blockchain transactions and off-chain social media activity, we analyze over one hundred NFT collections to uncover how different forms of participation structure community formation in decentralized environments. Using network analysis, we identify distinct ecosystem roles, such as long-term holders, active traders, and short-term speculators, and demonstrate how each produces markedly different network topologies, levels of cohesion, and pathways for influence. We complement this structural analysis with discourse analysis of social media engagement, revealing how narrative production, visibility, and sustained interaction persist even as transactional activity declines. Our findings show that communities centered on holding behavior evolve from transactional networks into socially embedded ecosystems characterized by dense ties, decentralized influence, and ongoing cultural participation, while trader- and speculator-dominated networks remain fragmented and transactional. By linking network structure with discursive dynamics, this study provides a sociotechnical framework for understanding how value, identity, and inequality are negotiated in Web3 spaces. The approach offers a scalable method for detecting patterns of inclusion, exclusion, and representational imbalance, advancing network-based research on digital communities beyond purely economic or technical accounts.
As Web3 architecture, artificial intelligence (AI), immersive environments, and connected devices converge, societies are moving from digitally mediated interaction to digitally programmed organisations, reshaping how value, labour, identity, learning, and participation are produced and governed. Programmable money, decentralised identity, AI-driven avatars, digital twins, and immersive environments illustrate how programmability collapses traditional distinctions between infrastructure, governance, and social behaviour. While these systems offer significant potential for inclusion, efficiency, and innovation, they also introduce profound ethical risks. This means that ethical challenges should become core governance elements, as code, data, and automated systems increasingly mediate trust, agency, and power at scale. Ethical failures in digital systems can scale across platforms, populations, and jurisdictions. This paper conceptualises a structural shift in which institutional rules, incentives, and governance functions are increasingly executed directly within programmable digital infrastructure, making ethics, accountability, and trust intrinsic properties of system design.
Blockchain-Driven Healthcare Platform with Access-Controlled Record Management is a decentralized application designed to enhance the security, privacy, and accessibility of medical records. Traditional healthcare systems rely on centralized storage, making sensitive patient data vulnerable to breaches, manipulation, and unauthorized access. This project utilizes blockchain technology to provide a secure and tamper-proof environment for storing and managing healthcare data. Smart contracts are implemented to enforce access control, allowing patients to grant or revoke permission to doctors and healthcare providers. Medical records are securely stored using decentralized storage mechanisms, while blockchain maintains immutable references to ensure data integrity. The platform integrates Web3 technologies for secure user authentication and seamless interaction with the blockchain network. By eliminating intermediaries, the system improves transparency and trust among stakeholders. This solution demonstrates an efficient approach to managing healthcare data, ensuring confidentiality, integrity, and availability while addressing the limitations of traditional healthcare record systems in a modern, digital environment.
O estudo investiga barreiras de usabilidade em aplicações de Finanças Descentralizadas (DeFi) executadas em redes compatíveis com a Ethereum Virtual Machine (EVM), mostrando que problemas de fluxo, terminologia e feedback comprometem a adoção, especialmente entre iniciantes. Para enfrentar essas limitações, o trabalho propõe uma interface de usuário aprimorada e a compara a uma versão não otimizada usando métricas de desempenho, número de cliques e o questionário NASA-TLX. Os resultados indicam que a interface melhorada elevou a taxa de conclusão de tarefas de 76% para 89%, reduziu os cliques excedentes de 221 para 186 e diminuiu a carga cognitiva global aferida pelo NASA-TLX em todas as seis dimensões avaliadas, com destaque para demanda mental e frustração, inclusive entre usuários experientes, que relataram maior fluidez e previsibilidade. O artigo conclui que refinamentos de usabilidade voltados para aplicações financeiras descentralizadas são determinantes para elevar confiança e adoção, recomendando a padronização de processos, mensagens menos técnicas e a redução de etapas críticas para mitigar a fadiga de operações e ampliar o alcance da Web3.

The rapid growth of the event management industry has exposed significant challenges in traditional ticketing systems, including ticket fraud, duplication, unauthorized resale, and lack of transparency, as centralized platforms often fail to provide verifiable ownership and are vulnerable to manipulation. This paper proposes an NFT-Based Ticketing System that leverages blockchain technology to create a secure, decentralized, and transparent solution where each ticket is represented as a unique Non-Fungible Token (NFT) on the Polygon blockchain, ensuring immutability and authenticity. Smart contracts automate ticket minting, ownership transfer, resale regulation, and royalty distribution, enabling fair secondary market practices while maintaining control for event organizers. The system also incorporates a QR-based verification mechanism for real-time validation at event venues, preventing duplication and unauthorized access. Implemented as a decentralized application (DApp) using Web3 technologies and tested on the Polygon Mumbai testnet, the system demonstrates improved security, reduced fraud, efficient transaction handling, and enhanced user experience, thereby transforming traditional ticketing into a reliable and trustless digital ecosystem.
Web3 prediction markets, exemplified by Polymarket, have gained prominence for leveraging collective intelligence to forecast a wide range of social, political, and sports events. However, among the thousands of prediction market events, consensus disputes still arise due to imperfections in market mechanisms. On Polymarket alone, the trading volume involving disputed events has reached $972,370,804.71, underscoring the critical need for objective and efficient dispute resolution. In this study, we introduce large language models (LLMs) to: (1) evaluate whether web-enabled LLMs can reproduce the decision quality of UMA's on-chain voting process once a dispute has been raised, and (2) predict, based on event rules, which market events are likely to face future disputes before they occur. Our findings show that LLMs are unable to reliably predict which events will become disputed in advance; however, once a dispute is initiated, web-enabled LLMs achieve 89.58% agreement with UMA's final resolutions and demonstrate strong stability.
India’s aspiration to emerge as a developed nation by 2047 under the vision of Viksit Bharat necessitates the identification and scaling of localized innovations. Odisha, characterized by its socio-cultural diversity and rapid technological transition, presents a compelling case as a living laboratory for future-ready developmental models. This study positions Odisha at the intersection of three transformative domains: algorithmic welfare systems, governance challenges arising from silent urbanization, and the digitization of cultural heritage through Web3 technologies such as NFTs. By integrating quantitative modeling, qualitative fieldwork, and policy analysis, the study proposes a framework for culturally rooted, inclusive, and decentralized development. The findings suggest that Odisha’s experiments in adaptive welfare delivery, the recognition of hybrid urban spaces, and digital cultural economies not only address local challenges but also offer scalable insights for national policy. The state thus emerges as a microcosm of a technologically empowered, socially equitable, and culturally vibrant Viksit Bharat.
Purpose - This study examines how Web3 technologies—including blockchain, non-fungible tokens (NFTs), and decentralized finance (DeFi)—affect the business models of sports organizations and the engagement behavior of fans. The research evaluates both the revenue and loyalty opportunities created by digital assets and the financial risks and regulatory challenges they introduce. Design/methodology/approach - A mixed-methods approach is employed, combining blockchain analytics, big data and social media monitoring, expert interviews, ethnographic observation of online fan communities, and systematic case analysis of NBA Top Shot, Chiliz/Socios.com, Sorare, and related platforms. Theoretical grounding draws on the Stimulus-Organism-Response (S-O-R) paradigm, the Fan Attitude Network (FAN) model, and Social Identity Theory (SIT). Findings - Fan tokens and NFTs create new revenue streams and deepen supporter loyalty through exclusive access, participatory governance, and gamified interactions. However, empirical evidence reveals high price volatility, speculative investor behavior, misleading marketing, and an unclear regulatory environment that expose fans to financial risk. Emerging markets such as Azerbaijan face additional structural barriers—limited fan culture depth, nascent regulation, and underdeveloped digital infrastructure—that preclude near-term viability of NFT-based fan engagement. Originality/value - This article is among the first to systematically integrate governance, financial risk, and regulatory dimensions of Web3 in sports within a single framework, moving beyond prior work focused narrowly on marketing and financial performance. It offers actionable implications for sports organizations, regulators, and platform developers. Research limitations/implications - The study is constrained by the rapidly evolving nature of Web3 technologies, jurisdictional variation in regulatory frameworks, and limited blockchain data accessibility for some platforms.
