The project's goal is to create an application that assures consumers don't have to rely solely on merchants to determine whether or not products are authentic. It also assures that producer may use this system to supply genuine products without having to run direct operated outlets, lowering product quality assurance costs dramatically. The trade in counterfeit goods is expanding, hurting the sales and earnings of businesses who are affected. This project proposes a fully-functional blockchain system to prevent product counterfeiting to ensure the identification and traceability of real products throughout the supply chain. Establishments only need to pay minimal transaction fees, and they no longer need to be concerned about the probability of obtaining counterfeit products. This project utilizes Ethereum blockchain and Remix to develop the application code in the form of a Smart Contract. For testing and implementation, Ganache and MetaMask are used, which simulates the blockchain environment and user account respectively. The Client-Side application leverages with Reactjs and Web3js to interact with smart contract and provide its functionalities to the users, maintaining the integrity of the system. Key Words: Ethereum, Anti-Counterfeit, Solidity, Web3js, Reactjs, Ganache

AI requires heavy amounts of storage and compute. As a result, AI developers are regular users of centralised cloud services such as AWS, GCP and Azure, compute environments such as Jupyter and Colab notebooks, and AI Hubs such as HuggingFace and ActiveLoop. There services are associated with certain benefits and limitations that stem from the underlying infrastructure and governance systems with which they are built. These limitations include high costs, lack of monetization and reward, lack of control and difficulty of reproducibility. At the same time, there are few libraries that allow data scientists to interact with decentralised storage in the language that data scientists are used to, and few hubs where they can discover and interact with AI assets. In this report, we explore the potential of decentralized technologies - such as Web3 wallets, peer-to-peer marketplaces, decentralized storage (IPFS and Filecoin) and compute, and DAOs - to address some of the above limitations. We showcase some of the libraries and integrations that we have built to tackle these issues, as well as a proof of concept of a decentralized AI Hub app, that all use IPFS as a core infrastructural component.
Recent developments in machine learning have shown that successful models do not rely only on huge amounts of data but the right kind of data. We show in this paper how this data-centric approach can be facilitated in a decentralized manner to enable efficient data collection for algorithms. Face detectors are a class of models that suffer heavily from bias issues as they have to work on a large variety of different data. We also propose a face detection and anonymization approach using a hybrid MultiTask Cascaded CNN with FaceNet Embeddings to benchmark multiple datasets to describe and evaluate the bias in the models towards different ethnicities, gender, and age groups along with ways to enrich fairness in a decentralized system of data labeling, correction, and verification by users to create a robust pipeline for model retraining.
Oil IT Journal editor Neil McNaughton reviews over 20 years of attempts to find a useful application for virtual reality technologies. From the Cave, fancy headsets of the last millennium, through Second Life, Google Glass and into the metaverse. But what exactly is the metaverse? Is it Web3? Is it blockchain? Will it be a closed world managed by Meta/Facebook. Or, as many in the IT universe seem to be hoping, an ‘open’ environment where all the GAFAMs can cash-in?

Novac je kao sredstvo plaćanja potreban oduvijek. Tijekom povijesti način i sredstvo kojim su se vršile zamjene mijenjao se mnogo puta pa je postala neophodna ideja novca kao sredstva plaćanja. Iako je novac danas nužan u svakodnevnom životu, postoje brojni problemi koje takva imovina donosi, primjerice inflaciju koja uništava ušteđevine brojnih građana. Do takve današnje situacije dovele su brojne loše odluke vladajućih tijekom povijest. Kako živimo u digitalnoj eri kada tehnologija napreduje kao nikad prije, mnogi očekuju da će novac potpuno prijeći u digitalni oblik. Ovaj rad u uvodu ima istaknute ciljeve, sadržaj i metodologiju istraživanja. Definirani su problem i predmet istraživanja. U drugom poglavlju koje zauzima najveći dio rada definiran je nastanak prve kriptovalute i objašnjena je blockchain tehnologija. Ta tehnologija ključ je za rad kriptovaluta i preko nje se događaju ključni procesi koji kriptovalute čine onim što one jesu. U ovom je poglavlju također objašnjen proces rudarenja koji pomoću rudara potpuno zamjenjuje potrebu bilo kakve treće strane kod procesa slanja i primanja kriptovaluta. Prikazani su brojni drugi sektori u kojima se blockchain tehnologija danas također primjenjuje. Ovo poglavlje pobliže prikazuje najveću svjetsku kriptovalutu bitcoin te navodi kako je nastao, koje mogućnosti pruža, gdje se danas nalazi u očima velikih i malih ulagača i kakva su očekivanja daljnjeg kretanja cijene i njegovog prihvaćanja. Nadalje se prikazuju sve ostale kriptovalute, odnosno altcoini. Navodi se koje su sve mogućnosti danas dostupne i kako se kripto tržište naglo razvilo u posljednje dvije godine, zbog decentraliziranog financiranja, NFT-ova, stablecoina, metaversa, web3-a i brojnih drugih mogućnosti koje to mlado tržište nudi. Treće poglavlje otkriva ulogu kriptovaluta u suvremenom poslovanju, pobliže prikazuje pravni i ekonomski aspekt kriptovaluta, kao i zabludu da su kriptovalute namijenjene za ilegalne radnje. U četvrtom poglavlju prikazana je metodologija rada i provedeno je istraživanje 61 ispitanika preko online upitnika. Od tri postavljene hipoteze prve dvije su odbačene, a treća je prihvaćena. Na temelju cjelokupnog rada otkrilo se čemu sve kriptovalute služe i kako se mogu podijeliti, došlo se do temeljnih zaključaka o kriptovalutama i globalnom mišljenju te do brojnih istraživačkih zaključaka i preporuka za buduća istraživanja.

Since the widespread use of cryptocurrency, blockchain technology start to be adapted in various applications. Some businesses are already adopting blockchain technology because of its advantages such as data integrity and privacy. One of them is Web 3.0. Web 3.0 puts forward data decentralization so that users can choose what data will be sent to the server. User data is provided locally with the help of a crypto wallet and the server just receives wallet info. With this mechanism, user privacy can be maintained directly by the user himself. All data will be processed at the users' end first before being sent to the server. With the new mechanism of web 3.0 and the advantages of blockchain, we build an application to authenticate students' login activities and grant roles to them based on their wallets. In this paper, we use the prototyping model as the method to build the application. We managed to utilize students’ wallet addresses as credentials. And with the help of Web3 module, we managed to decentralize the authentication process. And as a result of the successful authentication process, students can access their data based on their roles.

The design of tokenomics, i.e., distribution and circulation mechanisms of cryptocurrency tokens, is a top priority for almost all Web3 applications which relates to their own economic systems via native cryptocurrency tokens. Unfortunately, while the sustainability of tokenomics largely determines the long-term development of a Web3 application, the tooling support for the design of it has been far too insufficient. A common practice at the time of writing is to specify tokenomics with a combination of documents, spreadsheets, code scripts etc.. In this paper, we introduce the TMI development platform for the modelling and analysis of Web3 tokenomics. TMI creates a domain-specific language and its graphical development environment for developers to succinctly model crypto-economic relations in a drag-and-drop way. Based on created models, TMI allows developers to formally analyse their tokenomics via checking fundamental economic properties, e.g., The core team of a project holds less than 20% of the project token in 36 months. A demonstration video of TMI is available at https://youtu.be/LDn-eRxPMTw.
Many people donate money to fund organizations, but very rarely do those donors have information about where those donations go. Donation platforms are both non-transparent and also leave a large portion of potential donors unnoticed: gamers [1]. This paper explores the concept of utilizing blockchain technology and its existence as a web3 token-based platform in order to provide transparency for donation routes, showing donors and other companies exactly where donations are coming from and where that money is going. Our application utilizes HTTP requests in order to greatly increase compatibility, and also uses multiple private key encryptions in order to ensure that any user data or information and monetary transactions are kept secure and private [2].

Over time, distribution systems have begun to include increased distributed energy resources (DERs) due to the advancement of auxiliary power electronics, information and communication technologies (ICT), and cost reductions. Electric vehicles (EVs) will undoubtedly join the energy community alongside DERs, and energy transfers from vehicles to grids and vice versa will become more extensive in the future. Virtual power plants (VPPs) will also play a key role in integrating these systems and participating in wholesale markets. Energy trading on a peer-to-peer (P2P) basis is a promising business model for transactive energy that aids in balancing local supply and demand. Moreover, a market scheme between VPPs can help DER owners make more profit while reducing renewable energy waste. For this purpose, an inter-VPP P2P trading scheme is proposed. The scheme utilizes cutting-edge technologies of the Avalanche blockchain platform, developed from scratch with decentralized finance (DeFi), decentralized applications (DApps), and Web3 workflows in mind. Avalanche is more scalable and has faster transaction finality than its layer-1 predecessors. It provides interoperability abilities among other common blockchain networks, facilitating inter-VPP P2P trading between different blockchain-based VPPs. The merits of DeFi contribute significantly to the workflow in this type of energy trading scenario, as the price mechanism can be determined using open market-like instruments. A detailed case study was used to examine the effectiveness of the proposed scheme and flow, and important conclusions were drawn.
<ns4:p>Scientists write research articles, process ethics reviews, evaluate proposals and research, and seek funding. Several strategies have been proposed to optimize these operations and to decentralize access to research resources and opportunities. For instance, we previously proposed the trinity review method, combining registered reports with financing and research ethics assessments. However, previously proposed systems have a number of shortcomings, including how to implement them, e.g., who manages them, how incentives for reviewers are paid, etc. Various solutions have been proposed to address these issues, employing methods based on blockchain technologies, called “decentralized science (DeSci)”. Decentralized approaches that exploit these developments offer potentially profound improvements to the troubled scientific ecosystem. Here, we propose a system that integrates ethics reviews, peer reviews, and funding in a decentralized manner, based on Web3 technology. This new method, named ABCDEF publishing, would enhance the speed, fairness, and transparency of scientific research and publishing.</ns4:p>
Web3, one of the novel paradigms which may drive the evolution of the future Web, is offering an invaluable volume of data stored in the supporting blockchains. Researchers from different fields such as network science, computational social science and data mining, might benefit from these large collections of temporal and heterogeneous data capturing different kinds of interaction among people and between people and the platforms. In this study we focus on a specific issue related to these modern techno-social systems, i.e. the understanding of the rules driving their growth. To reach this goal, we performed an analysis based on graph evolution rules - GERs - on different networks gathered from Web3 platforms such as Steemit or OpenSea. Graph evolution rules mining is a frequency-based method for evaluating network evolution which does not require any prior growth process for disentangling how networks evolve. By comparing the evolution rules of social network platforms and asset trading services through GER profiles, we observe that some evolution rules are common to all Web3 platforms, regardless of the system specificity. On the other hand, in specific cases, the frequency of graph evolution rules is influenced by the nature of the platform: whereas social and token-transfer networks are characterized by rules which increase network transitivity and reciprocity, NFT trading networks, especially those specialized in a specific type of digital asset, are driven by rules which form trading chains. These findings suggest that the GER approach and the GER profiles are a good starting point to get insights into the evolutionary behavior of a network and to define a classification of graph evolution rules.
Web3 is leading a wave of the next generation of web services that even many Web2 applications are keen to ride. However, the lack of Web3 background for Web2 developers hinders easy and effective access and transition. On the other hand, Web3 applications desire for encouragement and advertisement from conventional Web2 companies and projects due to their low market shares. In this paper, we propose a seamless transition framework that transits Web2 to Web3, named WebttCom, after exploring the connotation of Web3 and the key differences between Web2 and Web3 applications. We also provide a full-stack implementation as a use case to support the proposed framework, followed by interviews with five participants that show four positive and one natural response. We confirm that the proposed framework WebttCom addresses the defined research question, and the implementation well satisfies the framework WebttCom in terms of strong necessity, usability, and completeness based on the interview results.
Sustainable, immutable, and affordable data storage to leading universities, research institutions, enterprises, and Web3 organizations.

In order to reduce limitations and as a practical substitute for voting on paper, electronic voting has developed gradually as a feasible alternative. The last decade's worth of related studies implies that, building a secure e-voting system using web 2.0 technology that assures the integrity of the votes while also giving transparency has been a long-standing difficulty. In a network of centralized systems, a single party has the right to administer data sources. Since the centralized voting systems are more vulnerable to data manipulation issues, the trust has faded in the voters on behalf of the entire process. In this paper authors discuss the solution with blockchain which is secured. The proposed implementation is ideal for small or medium-scale elections, and this includes several basic components of our methodology in three fictitious modules: the administrative module, the Voters module, and the Blockchain module. Node JS, Ganache, and Web3 JS are used as the main technologies. In conclusion, it is expected to implement a secure system for conducting web-based digital voting that ensures the integrity of the votes registered. Furthermore, it intends to enhance the system in the future to accommodate large-scale elections with a viable solution to the blockchain trilemma issues.
The rise of Web3 and related regulations have brought data privacy concerns to the forefront for brands and marketers. With the rise in legislation, the deprecation of third-party cookies and an eye towards transparency, Web3 promises a more open, permissionless online environment. This has implications, from ad targeting to the storage and collection of user data. New concepts including zero-party data, micro-experiences and non-fungible tokens (NFTs) represent trends that are emerging with Web3, but the future is still to be defined. Marketers must understand the implications of the changing data privacy landscape and discover new and creative ways of sourcing and collecting data that follow the new guidelines that are being established by legislators, as well as by walled gardens such as Apple, Meta and Google. To do so, they will have to experiment and innovate. Here, we will explore the evolution of the web from its earliest version into the future. We will also review the different ways marketers currently collect and use customer data. Finally, we will explore new ways for brands and marketers to stay relevant in this evolving digital ecosystem with zero-party data, integrated marketing technology, customer-centric governance and NFTs.
