Electronic First Information Report (e-FIR) is a basic document filed to the police stations by a victim or someone on his/her behalf when a cognizable offense such as murder, kidnapping, rape, theft, etc. is committed. In the e-FIR database, the offense&s;s record can be compromised due to its centralized nature, and further the intentional registration of false e-FIR can occur. Thus, data integrity and transparency are key concerns in e-FIR database. In this paper, e-FIR data integrity and false registration appended with police stations in a centralized database are addressed via a consensus-based distributed blockchain solution, as an integral part of a smart city environment. Specifically, a smart contract based intelligent framework has been utilized to explore the potential of Ethereum blockchain in providing integrity to e-FIR data stored in a police station&s;s database. Local database is interfaced with Ethereum blockchain using Web3 Remote Procedure Call (RPC) protocol. Multiple simulations have been performed to evaluate the performance of the proposed framework. Our results show a trade-off between different hashing algorithm security level for the offenses data and number of transactions stored in a single block on blockchain ledger.
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.

The metaverse, as a rapidly evolving socio-technical phenomenon, exhibits significant potential across diverse domains by leveraging Web3 (a.k.a. Web 3.0) technologies such as blockchain, smart contracts, and non-fungible tokens (NFTs). This survey aims to provide a comprehensive overview of the Web3 metaverse from a human-centered perspective. We (i) systematically review the development of the metaverse over the past 30 years, highlighting the balanced contributions from its core components: Web3, immersive convergence, and crowd intelligence communities, (ii) define the metaverse that integrates the Web3 community as the Web3 metaverse and propose an analysis framework from the community, society, and human layers to describe the features, missions, and relationships for each community and their overlapping sections, (iii) survey the state-of-the-art of the Web3 metaverse from a human-centered perspective, namely, the identity, field, and behavior aspects, and (iv) provide supplementary technical reviews. To the best of our knowledge, this work represents the first systematic, interdisciplinary survey on the Web3 metaverse. Specifically, we commence by discussing the potential for establishing decentralized identities (DID) utilizing mechanisms such as profile picture (PFP) NFTs, domain name NFTs, and soulbound tokens (SBTs). Subsequently, we examine land, utility, and equipment NFTs within the Web3 metaverse, highlighting interoperable and full on-chain solutions for existing centralization challenges. Lastly, we spotlight current research and practices about individual, intra-group, and inter-group behaviors within the Web3 metaverse, such as Creative Commons Zero license (CC0) NFTs, decentralized education, decentralized science (DeSci), and decentralized autonomous organizations (DAO). Furthermore, we share our insights into several promising directions, encompassing three key socio-technical facets of Web3 metaverse development.
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.

The quantity and diversity of stakeholders in space is increasing and centralised management of their assets is becoming more complex. New technologies in Web3 such as Decentralised Autonomous Organisations (DAOs) can bridge the communication gap with neutral and automated systems, and distribute currently centralised processes that are inherently decentralised by nature. One of these processes is Satellite-based Emergency Mapping (SEM) for Disaster Response Management (DRM). With automated decision strategies and transparent ledgers, a fairer and more accessible system can be built to handle the increase in stakeholders as well as the increasing number of natural disasters occurring. A DAO also address' the key issue with the current SEM process, such as decreasing the current three days wait, required to produce the necessary processed and analysed data for end users, after the disaster occurs. Moreover, with fleets of satellites belonging to different governmental and private organisations, a specific central authority cannot be identified to manage the process in an efficient and equitable way. The paper discusses the need for a more decentralised and automated system for DRM by presenting evidence of current bottlenecks and lays the foundations of the first DAO for on-orbit assets management and demonstrates which Web3 technologies could further improve SEM in this first phase of charter activation.

This paper presents a proof-of-concept (PoC) that leverages Web3 technology, specifically blockchain and Non-Fungible Tokens (NFTs), to create a secure, transparent, and fair reseller market without the need for a trusted third party. The PoC demonstrates that NFTs can be used to authenticate items, build trust between parties and establish verifiable product own-ership. By paralleling NFT transfers with the sale of items, the practicality of selling counterfeit goods is reduced. Furthermore, the blockchain-based storage of product information enables verification of origin, history, and authenticity by any involved party, fostering transparency and equal access to information for buyers and sellers. We demonstrate that Web3 technology can effectively address critical issues in traditional reseller markets, offering substantial benefits to all parties involved.

The advancements of the metaverse has validated a new world of possibilities with Web2 and Web3 technologies that are increasingly immersive, interconnected, spatial and decentralized. One of the key Web3 technologies that is intersecting with the metaverse is blockchain technology, that has now imbued metaverse worlds and platform as what are now identified as Layer-1 and Layer-2 metaverse, and in tandem the intersecting of decentralized Web3 technologies including but not limited to metaverse currencies and cryptocurrencies, non-fungible tokens and tokenization, marketplaces, digital wallets, and blockchain main and side-chain networks. In combination with interoperable and interconnected avatars, the metaverse is evolving beyond phygital experiences and asset architecting into financial experiences and asset trading. This research paper investigates the intersections between the metaverse and Web3 emerging technologies by firstly conducting a systematic literature review of the metaverse and its intersection with emerging technologies which currently has a dearth in academic and research literature despite the developments of the Web3 metaverse and its Layer-1 Layer-2 protocol. The review is followed by pilot-testing the metaverse platforms intersecting with Web3 technologies in real-world, particularly on the use of buy-and-sell, trading and item ownership under decentralized finance and financial technology. Finally, the research assesses the resulting metaverse based on user reviews and experiences on the feasibility of Web3 metaverse. The intersection of Web3 and the metaverse is still an early adoption of IR4.0 emerging technologies, yet the convergence of the metaverse, blockchain technologies and advancements in artificial intelligence is ultimately the precursor to the future Web4.
Finansal piyasaların eksiklikleri, merkezi finansal aracı kurumların gerekliliğini ortaya koymuş ve bu kurumlar, müşterilerinin ihtiyaçlarını karşılamada başarılı olmuştur. Ancak hala ülkelerarası para transferi gibi bazı hizmetler için yüksek masraflar ödenmektedir. Ayrıca, çağımızın hızlı ve verimli yeni uygulamalara ve iş modellerine ihtiyacı vardır ve mevcut kurumlar bu gereksinimlere tam olarak yanıt verememektedir. Özellikle COVID-19 ile birlikte dijitalleşmeye geçiş süreci hızlanmış ve finansal piyasalar hızlı bir değişim geçirmiştir. Kripto paralar, yapay zekâ ve blok zincir gibi Web3 bileşenleri, finansal piyasalarda önemli değişikliklere neden olmuş ve merkezi olmayan finansal ekosistemlerin gelişmesine olanak tanımıştır. Bu teknolojik gelişmeler, finansal hizmetlere daha fazla erişim sağlamış ve rekabeti artırmıştır. DeFi merkeziyetsiz finans anlamına gelmektedir ve de merkeziyetli finansa (CeFi)’ye göre birçok üstünlük barındırmaktadır. Kurumsal DeFi ise DeFi ekosisteminin yarattığı ürünlerin finansal kurumlarda kullanılmaya başlanmasını ve kurumların bu sürece uyum sağlayacak teknolojik altyapıyı edinmesini gerektirmektedir. DeFi, şirketlerin varlıklarını dijital tokenlara dönüştürerek bu ekosisteme entegre etmelerine ve finansal işlemlerini merkezi olmayan bir platform üzerinde gerçekleştirmelerine olanak tanır. Bu şekilde işlemler daha hızlı ve düşük maliyetli bir şekilde gerçekleştirilir ve piyasalardaki likidite artar. Bu çalışmanın amacı, DeFi kavramını ve DeFi'nin iş dünyasında nasıl uygulanabileceğini açıklamaktır. Bu çerçevede, DeFi'nin şirketler için potansiyel avantajları ve uygulanması adımları ele alınacak ve finansal kurumların bu dönüşümü başarıyla gerçekleştirmek için göz önünde bulundurmaları gereken faktörler açıklanacaktır. Ayrıca, DeFi'nin kurumsal düzeyde uygulanması sırasında ortaya çıkabilecek riskler ve bu riskleri etkili bir şekilde yönetmek için izlenmesi gereken stratejiler de incelenecektir.

The Morphogenetic Régulation approach (MR) contributes to the Morphogenetic Approach by explaining the material and ideational origins of change and stasis in agency, structure, and culture. In this paper, we focus on the expressive quality of ideas and systemic persistence in three research projects. The first demystifies inclusive governance and its adverse impacts. It shows how, contrary to institutions of governance, inclusiveness is not simply a norm but actually the explication of corporate agents’ ideas about rational choice institutionalism which leads to adverse impacts on vulnerable groups and ecologies known as adverse inclusion. The second investigates the role of ideas as adequacy and self-explication in guiding Palestinian actors’ actions towards the deepening of neoliberalization in Palestine. The third explains the relevance of the systemic persistence problematique for understanding how three juxtaposed themes – Web2, Web3, and Artificial Intelligence (AI) – are shaping the political economy and infrastructure of the Internet.

One of the most important paradigm shifts nowa-days regarding future 6G communication is related, from one side to the desire of bringing services and data as close as possible to the end users, and from another side, to empower the user with control over their data and personal information. In this vision, private 6G networks will shape trusted zones where data center services are placed at the edge of the network. The services will follow a Web3 approach, where decentralization and zero-trust mechanisms are predominant. In this environment, a decen-tralized authentication mechanism is needed. In this paper, we propose a 6G architecture and a blockchain-like authentication scheme based on Verifiable Credentials. Our model uses zero-trust technology for a better and more trusted Internet.
Randomness plays a pivotal role in modern online gaming, but disputes have arisen over the accuracy of stated winning chances, resulting in legal issues and financial setbacks for gaming companies. Fortunately, blockchain-based games offer a solution to the transparency and fairness issue regarding randomness. Furthermore, emerging blockchain technology like Sui Network enhances the efficiency of smart contracts by eliminating traditional web3 barriers, such as inefficiencies and expensive transaction fees. This unlocks the potential for extensive decentralized gaming applications. This paper aims to provide insights into designing a fair, verifiable, and efficient smart contract game on blockchain by the example of building raffles on the Sui Network. We explore efficient methods for implementing randomness on smart contracts, including DRAND committee-based decentralized random beacons and single private-key-based verifiable random functions (VRF). Then, progress from basic to comprehensive smart contract design. We addressed limitations in developing blockchain games in general, such as data input and storage space constraints. We propose corresponding solutions, encompassing the utilization of Object Tables, Delegate Object Creation, and Zero-Knowledge Proofs (ZKP) to optimize storage and input efficiency. After testing our designs, we found that the transaction fees for DRAND beacons and private-key-based VRFs are similar. Moreover, Object Tables incur higher overall transaction fees, while the ZKP setup fee is cheap but becomes very expensive during the verification process. Moreover, we identified suitable designs for different application scenarios by comparing the pros and cons of different smart contract implementations. Our findings provide valuable guidance for future researchers and developers in building random, fair, and verifiable games with smart contracts.

The growing popularity of Internet of Things (IoT) has triggered several researches in the industry and academic world. The objective is finding a good trade-off between security, privacy and reliability, without loosing scalability potential. To this end, blockchain technology, previously only applied in the context of cryptocurrencies, has been integrated with IoT applications (BIoT) to fulfill all these needs, bringing a decentralized approach and promoting new business logic ideas to the field. Despite the promising benefits of this integration, BIoT has faced scalability concerns, due to the complex task of handling massive data transactions that can be generated in monitoring IoT applications. In order to contribute with an alternative solution to this problem, this paper proposes a completely decentralized architecture designed for Smart Agriculture. It explores the InterPlanetary Name System (IPNS), as a name system that can be updated over time; the InterPlanetary File System (IPFS), as a Distributed File System (DFS) to store the IoT data; and a multichain network, built with public and private blockchains, delivering a full Web3 approach that can be applied in IoT data marketplace. Results obtained from evaluating a simulated Smart Vineyard scenario demonstrated that IoChain is capable of effectively managing massive data transmissions and dealing with the appearances of new IoT devices, without increasing transaction fees or transaction processing time.
We consider the problem of researcher output identification and its verification.Nowadays, researcher outputs verification is a challenging problem faced by institutions that want, for example, employ such a researcher.Usually, there is no verification, and the aforementioned institutions rely on trust that the received documents are authentic.Our solution is a based on blockchain technology, a public ledger with smart contracts, that is the root of emerging web3.We use the public wallet address as the researcher identification number and the wallet as the store of all researcher credentials.This paper presents ERC-721 standard-based solution and addresses the conference certification case.The solution proposed in this paper addresses two challenges that arise in collecting and verifying data on research output for managing, monitoring, and evaluating purposes.We show that the public wallet address can be successfully used as the researcher identification number, and the wallet can be used as a vault of all the researcher credentials.
The peer-to-peer (P2P) based distributed file system known as IPFS (InterPlanetary File System) has recently garnered significant attention as a decentralized storage solution in the Web3 landscape. However, IPFS operates on a voluntary participation basis, which can limit data availability. To enhance automated data availability on IPFS, an extended solution known as IPFS Cluster is being developed. This solution leverages a data replication approach. This paper proposes a Reed-Solomon based distributed content storage mechanism for IPFS, enhancing data availability and significantly improving storage efficiency compared to traditional replication methods. This technology is anticipated to serve as a fundamental building block for efficiently storing, managing, and utilizing large-scale, high-capacity digital content in various Web3 environments.

Programming has always been at the heart of technological innovation in the 21st century. With the advent of blockchain technologies and the proliferation of web3 paradigms of decentralised applications, smart contracts have been very instrumental in enabling developers to build applications that reside on decentralised blockchains. Despite the huge interest and potential of smart contracts, there is still a significant knowledge and skill gap that developers need to cross in order to build web3 applications. In light of this, we introduce MazzumaGPT, a large language model that has been optimised to generate smart contract code and aid developers to scaffold development and improve productivity. As part of this research, we outline the optimisation and fine-tuning parameters, evaluate the model's performance on functional correctness and address the limitations and broader impacts of our research.

Concerns over data confidentiality and security have become increasingly critical in the healthcare sector, given the need for immediate data accessibility. Traditional centralized systems face accessibility issues, necessitating a transformative solution, and blockchain technology emerges as a promising candidate. This research introduces a patient-controlled, blockchain-based system that efficiently manages and safeguards individuals' health-related data. By harnessing the Ethereum network and utilizing tools such as Ganache, Solidity, and web3.js, this system takes a systematic approach to overcome the limitations of centralized systems. Smart contracts, the basis of blockchain technology, serve as the backbone for storing and processing patients' data in a decentralized manner. Transactions are conducted securely through these smart contracts, ensuring patient privacy and data security. Notably, any modifications to transactions can be verified and propagated across the entire distributed network, enhancing data integrity. Complementing this system is a cryptocurrency wallet like MetaMask, providing a centrally controlled repository where records can be swiftly accessed and secured by authorized individuals, including doctors and patients. This integration significantly improves data accessibility and security within the healthcare domain. Ultimately, this research aims to leverage blockchain technology for simultaneous data retrieval, enhancing efficiency, credibility, and accessibility. It offers a robust framework for securely storing data with tailored access permissions and facilitates the safe transfer of patient medical records. In essence, it introduces a swift and secure health record system and an innovative protocol, promoting greater transparency and ownership of sensitive data in the healthcare sector through blockchain integration.
