With the growing interest in blockchain in both academic research and industry, the security and privacy of blockchains have attracted huge interest, even though only a small part of the blockchain platforms can achieve the set of abovementioned security goals in practice. Leveraging from the state-of-the-art security paradigms, we propose 5irechain protective covering which has the ability to continuously identify, map, scan, assess, and grade the risk portfolio of all the assets, vendors, and acquisitions of a company giving a hackers perspective to the company. The dashboard gives visibility of not just only the web2 infrastructure in place, but also covers the web3 space and allows 5ire to monitor all of its nodes and their activities including historical data, tracking large wallets, monitoring bot activity, detecting transaction stats and volume along with the ability to block possible large scale attacks.

Pod koniec 2021 roku szacowano, że 300 milionów osób na całym świecie posiadało jakąś formę kryptowaluty. Dwie największe dźwignie popularności kryptowalut to DeFi i NFT. Gdy na początku 2021 roku NFT, czyli niewymienialne tokeny, wzbudziły lawinę transakcji detalicznych, duże marki zaczęły zwracać na to uwagę. NFT dają możliwość zachowania cyfrowego IP i aktywowania społeczności internetowych w sposób, który nigdy wcześniej nie był osiągalny. Jednakże, jak dotąd, nie obserwuje się "web3-natywnego" podejścia do NFT ze strony dużych marek. Oznacza to, że żadna marka nie zmieniła swojej architektury Web 2.0 i nie zastąpiła jej całkowicie strukturą Web 3.0. Zamiast tego, globalne firmy przyjęły bardziej ostrożne podejście, udostępniając kolekcje NFT jako odrębne człony swojej oferty, a zarazem stymulując rozwój skupionych wokół nich społeczności. Tę fazę, którą można określić mianem Web 2.5, cechuje stopniowe wdrażanie nowych technologii, takich jak NFT, z korzyścią zarówno do samej lansującej je marki, jak i dla konsumentów. Producenci połączyli to, co najlepsze w Web 3.0, ze sprawdzonymi modelami rozwoju i promocji Web 2.0. Zasadniczo tym właśnie jest Web 2.5: stapianiem innowacyjnych technologii web3, m.in. NFT, z infrastrukturą Web 2.0 i tworzeniem środowiska, które zapewnia odbiorcom silne immersyjne doświadczenia kształtujące więź z marką. Procesy te przedstawiam w artykule na przykładzie marek z sektora mody i sztuki.

ABSTRACT The period from the mid-1990s to the mid-2000s saw the transformation of information and communication infrastructure. In the same period, TPRC evolved from a narrower focus on conventional telecommunications and information policy to “The Research Conference on Communications, Information, and Internet Policy.” Through the lens of my own interdisciplinary work on Internet policy and intersecting TPRC activity, this retrospective describes an arc of change that began at the 1994 TPRC and continued for about a decade. It combines description, commentary, and reflections on what this history might bode for TPRC as metaverses and Web3 progress from today’s hype to tomorrow’s Internet.

With the continuous development of web technology, Web 3.0 has attracted a considerable amount of attention due to its unique decentralized characteristics. The digital economy is an important driver of high-quality economic development and is currently in a rapid development stage. In the digital economy scenario, the centralized nature of the Internet and other characteristics usually bring about security issues such as infringement and privacy leakage. Therefore, it is necessary to investigate how to use Web 3.0 technologies to solve the pain points encountered in the development of the digital economy by fully exploring the critical technologies of digital economy and Web 3.0. In this paper, we discuss the aspects of Web 3.0 that should be integrated with the digital economy to better find the entry point to solve the problems by examining the latest advances of Web 3.0 in machine learning, finance, and data management. We hope this research will inspire those who are involved in both academia and industry, and finally help to build a favourable ecology for the digital economy.

The software industry's history is also its future. Its history has been defined by both abundance and scarcity, and its future will be, too. In the 1970s and 80s, perceived software scarcity led U.S. legislators to formally grant intellectual property protections to software creators. Later, a different kind of scarcity-a lack of access to source code-led the founders of the free and open source software movement to flip intellectual property protections on their head in an effort to better promote abundance. That movement proved wildly successful, with today's software industry based on vast amounts of freely available open source software resources that both organizations and individuals collaboratively build. Abundance and scarcity will also define software's future, but in different ways. The abundance that the open source software movement spawned is in the midst of a significant commercial phase. That sometimes means that commercial competitors bring to the table a scarcity mindset that conflicts with the norms that made that movement so successful. Intellectual property concerns at times derail what may otherwise be even greater software abundance. And because so much software is moving into the Cloud, trade secrecy may become the software industry's most important form of intellectual property to the extent the industry abandons open models of innovation. The software industry's growing dependence on artificial intelligence (AI) is likely to contribute to these trends. The software industry is increasingly becoming synonymous with the AI industry, as more and more software companies either rely on AI in running their services or provide AI products to the public. As with all software, these AI technologies are increasingly provided from the Cloud, where trade secrecy is not only possible, but often preferable. But trade secrecy may be even more likely in the AI context because much of the magic in implementing AI systems lies in the know-how to piece them together from available open source software resources, decades-old AI techniques, and data. Hence, to the extent that software and AI technologists spurn open innovation in favor of a scarcity mindset, trade secrecy is likely to become its dominant form of legal protection. The advent of web3 technologies may eventually change some of these trends. But for now, increasing secrecy seems the most likely outcome. I conclude by arguing that this shift to secrecy is likely preferable to other forms of intellectual property.

By supporting decentralized applications (DApps), modern blockchains have become the technology of choice for the Web3, a decentralized way for people to interact with each other. As the popularity of DApps is growing, the challenge is now to allocate shard or subnetwork resources to face the associated demand of individual DApps. Unfortunately, most sharding proposals are inherently static as they cannot be adjusted at runtime. Given that blockchains are expected to run for years without interruption, these proposals are insufficient to cope with the upcoming demand. In this paper, we present dynamic blockchain sharding, a new way to create and close shards on-demand, and adjust their size at runtime without requiring to hard fork (i.e., creating duplicated instances of the same blockchain). The novel idea is to reconfigure sharding through dedicated smart contract invocations: not only does it strengthen the security of the sharding reconfiguration, it also makes it inherently transparent as any other blockchain data. Similarly to classic sharding, our protocol relies on randomness to cope with shard-takeover attacks and on rotating nodes to cope with the bribery of a slowly-adaptive adversary. By contrast, however, our protocol is ideally suited for open networks as it does not require fully synchronous communications. To demonstrate its efficiency, we deploy it in 10 countries over 5 continents and demonstrate that its performance increases quasi-linearly with the number of shards as it reaches close to 14,000 TPS on only 8 shards.

Nowadays, connected devices are growing exponen-tially; their produced data traffic has increased unprecedent-edly. Information systems security and cybersecurity are critical because data typically contain sensitive personal information, requiring high data protection. An authentication system manages and controls access to this data allowing the system to ensure the legitimacy of the access request. Most of the current identification and authentication systems are based on a centralized architec-ture. However, some concepts as Cloud computing and Blockchain use respectively distributed and decentralized architectures. Users without a central server will own platforms and applications of the next generation of Internet and Web3. This paper proposes AuSDiDe, a new authentication system for the distributed and decentralized structure. This solution aims to divide and share keys toward different and distributed nodes. The main objective of AuSDiDe is to securely store and manage passwords, private keys, and authentication based on the Shamir secret sharing algo-rithm. This new proposal significantly reinforces data protection in information security.

In the last few years, the technological future becoming apparent by the introduction of smart contracts into mainstream technology, specifically in the development of Web3 and the metaverse. Smart contracts will play a vital role in the decentralization and autonomy of the day-to-day tasks that must be completed. Several literature reviews, considered secondary sources, highlight the current state of testing methods for smart contracts made for Blockchain applications. In this paper, we present the results from a systematic mapping study to give structure to the information found from primary sources. Systematic mapping is a well-known method to identify and categorize research papers in a field with an increasing amount of literature. For this systematic mapping, we searched for studies between 2017 and present-day (March 2022) and were able to find 303 results, from which 47 were selected, by specific inclusion and exclusion criteria, to be relevant to this study. A concept map was created from the information gathered from primary sources to the attributes such as research type, contribution type, blockchain network, smart contract language, development process, testing methods, and testing environment. We also categorized the trends and demographics found in the selected papers based on publication year, author’s country, and more. The results of this systematic mapping showed that this field is very new and quickly increasing with new research. The researchers that are interested in this field could use the results found to create opportunities for their future work.

Financial literacy among Generation Z is alarmingly low, especially around compound interest and credit. This paper presents an innovative, Web3-based gamified learning system that uses low-cost 3-D avatars and visual narratives to teach compounding concepts. By integrating NFTs for identity, interactive missions, and real-time compounding simulation within a metaverse environment, the platform aims to engage 18–24-year-olds intuitively and enhance knowledge retention. A prototype was implemented and evaluated with a randomized controlled trial (N = 100) comparing it to traditional text-based instruction. The Web3 gamified group outperformed the control group significantly (75 % vs 55 %, p < 0.01), with higher engagement scores and intent to apply concepts. Qualitative feedback highlighted the motivational effect of avatar growth and NFT rewards. Results show that Web3 gamification can meaningfully improve compound interest learning while remaining low-cost and scalable. Limitations include gas-cost friction and novelty bias. Future work includes deploying advanced financial topics, refining UX to mitigate over-gamification, and evaluating long-term retention and cross-cultural adoption.

<p>Since its introduction with Bitcoin in 2009, blockchain technology has received tremendous attention by academia, industry, politics and media alike, in particular, through extended blockchain-based visions such as smart contracts, decentralized finance, and, most recently, Web3. The critical prerequisite for any such blockchain-based vision to be turned into reality is uncapped scalability. Furthermore, and equally important, blockchain technology needs to transcend the stage of specialized tokens into an adaptive, heterogeneous tokenization platform. In this paper, we explain the Alphabill family of technologies that addresses both unlimited scalability and unrestricted adaptivity. We deliver a sharded blockchain technology with unlimited scalability and performance, called KSI Cash, which is based on a new form of electronic money scheme, the bill scheme. We present performance tests of KSI Cash that we have conducted with the European Central Bank and a group of eight national central banks from the Eurosystem in order to assess the technological feasibility of a digital euro, showing the system operating with 100 million wallets and 15 thousand transactions per second (under simulation of realistic usage), having an estimated carbon footprint of 0.0001g CO2 per transaction (Bitcoin = 100 kg and more); furthermore, showing the system operating with up to 2 million payment orders per second, an equivalent of more than 300.000 transactions per second (in a laboratory setting with the central components of KSI Cash), scaling linearly in terms of the number of deployed shards. We explain, in detail, the key concepts that unlock this performance (i.e., the concepts of the bill money scheme). The results provide evidence that the scalability of our technology is unlimited in both permissioned and permissionless scenarios, resulting into the Alphabill Money technology. Next, we contribute the architecture of a universal tokenization platform that allows for universal asset tokenization, transfer and exchange as a global medium of exchange, called Alphabill platform. We reveal the crucial conceptual and technical contributions of the platform's architecture and their interplay, including the data structures of KSI Cash and Alphabill Money, the dust collection solution of Alphabill Money, and the atomic swap solution of the Alphabill platform.</p>

Digital organizations form part of the new wave of blockchain technologies, following Bitcoin and related cryptocurrencies. “Utopia of Abstraction” offers an analysis of the utopian promise of digital organizations through a reading of one such project, Colony. We provide a critique of the ideology of Colony's white paper, supplemented by readings of pages from its website, as a member of a genre of texts that promote their products through seemingly neutral, technical descriptions. Colony's texts suggest an abstract, contextless and scaleless organizational solution—powered by smart contracts on a blockchain—that, according to its proponents, might be applied to any social situation, from small firm to state-level governance. For its users, this organization combines a promise of sovereignty removed from that of the state, as well as implied financial returns. Our reading of Colony echoes the critiques of scholars arguing that cyberlibertarianism is a dominant politic of blockchain technologies. Furthermore, drawing on critiques of code as law and the elision of the social in smart contracts, we argue that Colony's vision presents a model of technical organization that substitutes for the state in the context of waning popular sovereignty. We ultimately suggest an understanding of digital organizations reminiscent of the settler colonial situation: the assumption of an empty social space to be filled, and the promise of sovereignty and riches for those occupying it. Analysis of these logics is relevant as hype increases around non-fungible tokens, Web3, and the corporate metaverse as well as data practices more widely.
