Mundane is the New Radical: The Resurgence of Energy Megaprojects and Implications for the Global South [Opinion]
NFT-Based Blockchain-Oriented Security Framework for Metaverse Applications
The Metaverse is rapidly evolving, bringing us closer to its imminent
reality. However, the widespread adoption of this new automated technology
poses significant research challenges in terms of authenticity, integrity,
interoperability, and efficiency. These challenges originate from the core
technologies underlying the Metaverse and are exacerbated by its complex
nature. As a solution to these challenges, this paper presents a novel
framework based on Non-Fungible Tokens (NFTs). The framework employs the
Proof-of-Stake consensus algorithm, a blockchain-based technology, for data
transaction, validation, and resource management. PoS efficiently consume
energy and provide a streamlined validation approach instead of
resource-intensive mining. This ability makes PoS an ideal candidate for
Metaverse applications. By combining NFTs for user authentication and PoS for
data integrity, enhanced transaction throughput, and improved scalability, the
proposed blockchain mechanism demonstrates noteworthy advantages. Through
security analysis, experimental and simulation results, it is established that
the NFT-based approach coupled with the PoS algorithm is secure and efficient
for Metaverse applications.Comment: 10 page
Money & Trust in Digital Society, Bitcoin and Stablecoins in ML enabled Metaverse Telecollaboration
We present a state of the art and positioning book, about Digital society
tools, namely; Web3, Bitcoin, Metaverse, AI/ML, accessibility, safeguarding and
telecollaboration. A high level overview of Web3 technologies leads to a
description of blockchain, and the Bitcoin network is specifically selected for
detailed examination. Suitable components of the extended Bitcoin ecosystem are
described in more depth. Other mechanisms for native digital value transfer are
described, with a focus on `money'. Metaverse technology is over-viewed,
primarily from the perspective of Bitcoin and extended reality. Bitcoin is
selected as the best contender for value transfer in metaverses because of it's
free and open source nature, and network effect. Challenges and risks of this
approach are identified. A cloud deployable virtual machine based technology
stack deployment guide with a focus on cybersecurity best practice can be
downloaded from GitHub to experiment with the technologies. This deployable lab
is designed to inform development of secure value transaction, for small and
medium sized companies
Socially Beneficial Metaverse: Framework, Technologies, Applications, and Challenges
In recent years, the maturation of emerging technologies such as Virtual
Reality, Digital twins, and Blockchain has accelerated the realization of the
metaverse. As a virtual world independent of the real world, the metaverse will
provide users with a variety of virtual activities that bring great convenience
to society. In addition, the metaverse can facilitate digital twins, which
offers transformative possibilities for the industry. Thus, the metaverse has
attracted the attention of the industry, and a huge amount of capital is about
to be invested. However, the development of the metaverse is still in its
infancy and little research has been undertaken so far. We describe the
development of the metaverse. Next, we introduce the architecture of the
socially beneficial metaverse (SB-Metaverse) and we focus on the technologies
that support the operation of SB-Metaverse. In addition, we also present the
applications of SB-Metaverse. Finally, we discuss several challenges faced by
SB-Metaverse which must be addressed in the future.Comment: 28 pages, 6 figures, 3 table

Runtime Management of Artificial Intelligence Applications for Smart Eyewears
Artificial Intelligence (AI) applications are gaining popularity as they
seamlessly integrate into end-user devices, enhancing the quality of life.
In recent years, there has been a growing focus on designing Smart EyeWear (SEW) that can optimize user experiences based on specific usage
domains. However, SEWs face limitations in computational capacity and
battery life. This paper investigates SEW and proposes an algorithm
to minimize energy consumption and 5G connection costs while ensuring high Quality-of-Experience. To achieve this, a management software,
based on Q-learning, offloads some Deep Neural Network (DNN) computations to the user’s smartphone and/or the cloud, leveraging the possibility
to partition the DNNs. Performance evaluation considers variability in 5G
and WiFi bandwidth as well as in the cloud latency. Results indicate execution time violations below 14%, demonstrating that the approach is
promising for efficient resource allocation and user satisfaction
The Metaverse: Survey, Trends, Novel Pipeline Ecosystem & Future Directions
The Metaverse offers a second world beyond reality, where boundaries are
non-existent, and possibilities are endless through engagement and immersive
experiences using the virtual reality (VR) technology. Many disciplines can
benefit from the advancement of the Metaverse when accurately developed,
including the fields of technology, gaming, education, art, and culture.
Nevertheless, developing the Metaverse environment to its full potential is an
ambiguous task that needs proper guidance and directions. Existing surveys on
the Metaverse focus only on a specific aspect and discipline of the Metaverse
and lack a holistic view of the entire process. To this end, a more holistic,
multi-disciplinary, in-depth, and academic and industry-oriented review is
required to provide a thorough study of the Metaverse development pipeline. To
address these issues, we present in this survey a novel multi-layered pipeline
ecosystem composed of (1) the Metaverse computing, networking, communications
and hardware infrastructure, (2) environment digitization, and (3) user
interactions. For every layer, we discuss the components that detail the steps
of its development. Also, for each of these components, we examine the impact
of a set of enabling technologies and empowering domains (e.g., Artificial
Intelligence, Security & Privacy, Blockchain, Business, Ethics, and Social) on
its advancement. In addition, we explain the importance of these technologies
to support decentralization, interoperability, user experiences, interactions,
and monetization. Our presented study highlights the existing challenges for
each component, followed by research directions and potential solutions. To the
best of our knowledge, this survey is the most comprehensive and allows users,
scholars, and entrepreneurs to get an in-depth understanding of the Metaverse
ecosystem to find their opportunities and potentials for contribution
Metaverse: A Vision, Architectural Elements, and Future Directions for Scalable and Realtime Virtual Worlds
With the emergence of Cloud computing, Internet of Things-enabled
Human-Computer Interfaces, Generative Artificial Intelligence, and
high-accurate Machine and Deep-learning recognition and predictive models,
along with the Post Covid-19 proliferation of social networking, and remote
communications, the Metaverse gained a lot of popularity. Metaverse has the
prospective to extend the physical world using virtual and augmented reality so
the users can interact seamlessly with the real and virtual worlds using
avatars and holograms. It has the potential to impact people in the way they
interact on social media, collaborate in their work, perform marketing and
business, teach, learn, and even access personalized healthcare. Several works
in the literature examine Metaverse in terms of hardware wearable devices, and
virtual reality gaming applications. However, the requirements of realizing the
Metaverse in realtime and at a large-scale need yet to be examined for the
technology to be usable. To address this limitation, this paper presents the
temporal evolution of Metaverse definitions and captures its evolving
requirements. Consequently, we provide insights into Metaverse requirements. In
addition to enabling technologies, we lay out architectural elements for
scalable, reliable, and efficient Metaverse systems, and a classification of
existing Metaverse applications along with proposing required future research
directions
