Introduction
Museums are institutions that collect, preserve, and display cultural, historical, artistic, and scientific artifacts and specimens for public education and enjoyment.They play a pivotal role in conserving and presenting the diversity of human accomplishments and natural wonders.Museums often facilitate educational and research opportunities, enabling the public to engage with and appreciate the richness of human culture and the natural world.Serving as invaluable repositories of history, they provide insights into ancient civilizations, lifestyles, and cultural evolutions [1].Through exhibits and artifacts, museums vividly illustrate how people lived across different eras, showcasing technological advancements, artistic achievements, and historical events.Visitors and students gain tangible connections to history, deepening their understanding of their cultural heritage.By exploring museum collections, people engage in experiential learning, grasp historical contexts, and develop an appreciation for the multifaceted aspects of human civilization, thereby reinforcing museums as dynamic educational tools that enrich our understanding of history and foster a lifelong respect for our shared heritage [2].
The term Metaverse refers to a collective of fully immersive digital environments where users interact through 3D avatars [3].Characterized by sociality, multitechnology convergence, and hyper-spatio-temporality, the Metaverse employs major technologies such as Artificial Intelligence, Augmented Reality, Virtual Reality, Mixed Reality, Blockchain, Edge Computing, Networking, and the Internet of Things [4].The term gained prominence when Facebook's CEO rebranded the company as Meta.In this virtual space, users engage in a myriad of activities including socializing, connecting, learning, working, shopping, playing, and more [5].Users can also purchase property or assets within the virtual world.Metaverse applications are increasingly popular across various domains such as education, gaming, shopping, industrial practices, concerts, and amusement parks.
The decline in interest and attendance among younger generations in traditional museums is primarily due to their growing use of digital devices and social media platforms.Accustomed to digital experiences, this generation may find traditional museums less appealing.Moreover, traditional museum collections are often scattered, requiring specific times and spaces for exhibitions [6].The gradual decline in museum attendance reflects shifting leisure preferences, a trend that predates the COVID-19 pandemic but was exacerbated by it, leading to prolonged closures of museums.This shift pushed people further into digital spaces, prompting institutions to explore innovative methods such as augmented reality and interactive exhibits to create immersive and engaging experiences that resonate with visitors' interests.A control group was established to analyze the performance of the digital museum setup.Two museums were selected for comparison: Museum-A, which uses a traditional display mode, and Museum-B, which employs a digital display.The study compared outcomes across four dimensions: interactive comparison, entertainment comparison, experience comparison, and content richness comparison.Results indicated that the digital museum outperformed the traditional museum in each aspect.
Metaverse Museums, like their traditional counterparts, utilize modern digital technologies to present history, culture, and art in immersive ways.They are crucial for engaging a generation that increasingly favors digital spaces over traditional learning methods.Metaverse Museums are globally accessible, breaking geographical barriers and allowing worldwide exploration of collections.They prioritize visitor participation and interaction, facilitating collaboration on projects and participation in virtual events and lectures.These digital venues also contribute to the preservation of cultural heritage, ensuring accessibility for future generations and promoting long-term cultural sustainability by mitigating risks associated with physical decay or destruction.
The declining interest and reduced attendance among the younger generation in traditional museums pose a significant challenge.This trend, compounded by an increased focus on social apps and digital devices, diminishes the appeal of cultural institutions.The situation worsened during the COVID-19 pandemic with the enforced closure of museums.Addressing this disengagement and finding effective strategies to attract and retain younger visitors through the incorporation of innovative technologies and the creation of compelling, immersive experiences is imperative.This study addresses the following research questions:   The paper is structured into five sections, each contributing to the exploration of digital reconstruction and virtual reality for cultural heritage preservation.Section "Introduction" introduces the research, underscoring its significance and outlining its objectives.Section "Literature review" presents a comprehensive review of existing literature, setting the stage for the study.Section "Proposed framework" describes the proposed framework, detailing the methodologies chosen for digital reconstruction and virtual reality development.Section "Implementation and Deployment" presents the research results, showcasing findings derived from the framework's application.Finally, Section "Evaluation" offers a summary, discussing key findings, their implications, and suggesting future research directions.References are meticulously cited throughout the paper to ensure proper attribution.

This section provides a detailed overview of all selected papers.The selected articles were thoroughly researched to assess their relevance and contributions.It begins by discussing the search results obtained through the defined search string.The section then addresses the evaluation scores assigned to the selected papers.Finally, it offers comprehensive discussions aimed at analyzing the findings and integrating key insights from the literature.The related research in the field of Metaverse museums or Digital Museums encompasses a broad array of strategies and implementations.Some studies focus on theoretical frameworks, while others concentrate on practical design considerations for virtual spaces.Our review utilizes information from multiple research articles to better understand and develop Metaverse museums.Examples of Metaverse museums examined in this paper include the Louvre in Virtual Reality, the Museum of Other Realities, and the British Museum in Augmented Reality.VR Visionaries: Exhibition Hall of Contemporary Art, Los Angeles, also provides unique experiences and insights for our study of the evolving landscape of virtual cultural institutions.
Museums are embracing the digital era, a transformation accelerated by the impact of COVID-19.Museums currently offer virtual events like tours and lectures on their websites, but they have not yet constructed a complete museum in Virtual Reality or the Metaverse.The shift from real to digital could be cost-effective, eliminating expenses for labels, text on walls, and reducing the need for visitors to crowd close to artworks to read physical communication.Since the pandemic, individual screen time has increased, with smart devices becoming a major part of people's lives.The Metaverse offers fresh opportunities for museums to reach a broader and more diverse audience.The alignment of real and virtual aspects of museums can enhance the visitor's experience, reducing the historical separation and inequality between museums and visitors [7].
The use of technology to modernize culture and heritage spaces is gaining attention and popularity.The field of museology is undergoing changes due to advancements in digital technology, with immersive exhibitions becoming particularly popular.Web 3.0 is more advanced and creates challenges for the museum community.Virtual spaces allow users to socialize, build their own structures, and even create buildings, such as museums.This paper [8] explores the potential of 3D environments in museums, emphasizing how they offer a more immersive and social experience compared to the conventional web.It also discusses examples of cultural institutions thriving in these virtual spaces.
In this paper [9], a virtual platform is designed for the Chime Bells of Marquis Yi of Zeng, one of China's most treasured cultural heritage sites.The Chime Bells are available for tourists to view only from a distance; they are not allowed to touch or manipulate the chime bells and other exhibits in any manner while viewing.The paper creates an engaging and instructive museum environment in which visitors can fully immerse in the real hall of Chime Bells and even create music by ringing the bells.Laser scanning techniques are employed to visualize the Chime Bells of Marquis Yi of Zeng and all other displays.3D models are constructed and optimized using the PBR (Physically Based Rendering) workflow.Utilizing LOD (Level of Detail) for specific elements ensures consistent detail while minimizing rendering costs.A roaming system for scenes is implemented, facilitating user interaction with exhibits for multimedia information and enhancing overall interactivity and orientation.A multiplayer mode is also provided to encourage multiple visitors to communicate and share their experiences.
The Metaverse, viewed as the internet's next evolution, provides an open virtual shared environment.It's the perfect platform for showcasing virtual realities, bridging the gap between the actual and virtual worlds, and offering immersive experiences that transcend time and place.This study [10] focuses on the digitization, reconstruction, and virtual reality development of Meret-Neith's tomb in Umm El Qa'ab, the First Dynasty King's cemetery in Abydos, Egypt.The tomb is precisely digitally recreated using photogrammetry.In light of the current digital revolution, the study investigates the use of virtual reality to convey important historical events and remote examples of ancient architecture.The aim is to fully immerse guests in a virtual environment, giving them the opportunity to actively participate and form opinions by taking on the role of characters in the historical setting.The study focuses on the rebuilding of early dynastic Egyptian archaeological sites; Queen Meret-Neith's tomb in Umm el Qa'ab, which dates to 2950 BC, serves as an example.Remote architectural and cultural heritage that has been digitized makes previously inaccessible places virtually accessible.Virtual exhibitions have the power to transform the way that cultural heritage is experienced and communicated in the realms of education and entertainment by fostering emotional bonds between viewers and the artifacts on display [11].
In this paper [12], the authors propose ArtVerse, a novel human-machine collaborative creation paradigm for art in the Metaverse.The system utilizes machines to perform creation, exploration, and evaluation, assuming the human role within the artistic process.It establishes a decentralized art organization within the Metaverse comprising Human Painters, Digital Painters, and Robotic Painters.Human Painters provide training to machines, while Robotic and Digital painters collaborate as a unified machine entity.NFTs are employed to secure users' assets, like artwork, and track the steps involved in the creation of masterpieces.They also designed a group for digital painters to mimic the social collaboration seen among human painters.This adds a social aspect to the artistic platform.Participants can work together on art projects by sharing their painting knowledge and models, and they also vote on painting experiments.To secure these collaborations, they used Smart contracts (Table 1).
Navarrete Trilce [16] integrated digital technology with heritage museums, allowing cultural heritage to be shared digitally.This approach aims to attract more people to engage in cultural tourism while enhancing the transmission of cultural heritage.
CyArk, a non-profit organization, is committed to the widespread dissemination of cultural heritage through digital channels.Their mission aims to connect diverse audiences with heritage by leveraging digital documentation and creating immersive experiences across web, mobile, and other platforms.This initiative is designed to spark reflection, conversation, and imagination.As part of their Resonant project, CyArk has developed a remarkable virtual reality (VR) experience centered around the Balcony House at Mesa Verde National Park.This virtual reconstruction, achieved through advanced techniques like photogrammetry and LIDAR, offers a unique opportunity for users to engage deeply with the narratives embedded within the historical site.By navigating the digital replica of Balcony House, users interact with a virtual notebook and a walkie-talkie, exploring various narratives and completing missions.This immersive journey allows individuals to traverse the reconstructed structure, connecting with stories that span time and cultures, thereby providing a captivating and educational experience [22].
Mason Marco [23] created a digital museum using 3D display technology, which offers more interaction with visitors compared to traditional museums.Visitors can experience 3D animation elements in this 3D-based digital museum.Extended reality (XR) and virtual museums (VM) have been adopted by museums over the past two decades to support neurodiverse populations and meet varying generational expectations while focusing on community engagement and inclusivity.Initially, XR technologies enhanced exhibits in physical museums for educational purposes, but soon expanded to entire virtual museums and room-sized environments.It is now increasingly common for museums and UNESCO World Heritage Sites to feature digital twins.These virtual experiences assist neurodiverse visitors in preparing for their physical visits.This chapter explores how XR experiences and existing methods such as social stories and sensory maps can support neurodiverse visitors and their families both before and during museum visits [24].Techniques such as digital storytelling, sensory maps, and adaptive extended reality (XR) reach individuals with autism, ADHD, ADD, and other cognitive challenges.The proposed "story map" combines these elements into a personalized, narrative-driven digital expression of museum collections, offering support prior to the visit.Additionally, head-mounted displays (HMDs) and virtual reality (VR), which minimize external distractions and are particularly beneficial for those with stimuli sensitivity, allow individuals with sensory processing disorders to navigate the museum environment more comfortably, enhancing   1, The novelty of our proposed framework ArchaeoMeta lies in its holistic approach.Where individual papers have examined components such as 3D visualization, interactive platforms, or digital curation, ArchaeoMeta synthesizes these into a unified framework.It embodies a comprehensive strategy that begins with user interface optimization, extends through application and integration modules designed for immersive content interaction, and culminates in a museum showcase that leverages advanced rendering techniques.Crucially, ArchaeoMeta extends the narrative by incorporating governing bodies within its ecosystem, ensuring that virtual spaces adhere to curatorial and ethical standards akin to their physical counterparts.The inclusion of smart contracts for artifact security marks a pioneering step towards integrating Web 3.0 technologies with cultural dissemination, offering a forward-thinking approach to museum design and management.

Performance evaluation
In evaluating the "ArchaeoMeta" framework, we deployed its smart contracts on Ethereum's Sepolia testnet, focusing on scalability and latency as the number of users increased.

Evaluation setup
To assess the operational efficacy of the "ArchaeoMeta" framework, we deployed its associated smart contracts on the Ethereum Sepolia testnet.Our primary objectives were to determine the impact of increased visitor numbers on blockchain size and system latency.As shown in Table 2, We simulated visitor interactions, scaling up to 10,000 concurrent users, to analyze how the system manages heightened activity and data load.
We utilized a staged approach, beginning with a baseline of minimal activity (100 users) and incrementally increasing the load in phases-500, 1000, 5000, and finally 10,000 users.Each user was simulated by automated scripts that interacted with the smart contracts to mimic actions such as accessing, interacting with exhibits, and logging activities.Key performance metrics included transaction latency, gas costs, and block size growth (Table 2).
The results indicated that with a baseline of 100 users, the average transaction latency was approximately 15 s.However, as user numbers expanded to 10,000, the latency experienced a substantial increase, averaging around 2 min per transaction.This rise in latency corresponded with the increased demand for transaction processing and data recording on the blockchain as presented in Fig. 5.The analysis revealed that while ArchaeoMeta is capable of handling a significant number of users, the scalability of the Ethereum platform, as evidenced by increased latency with higher numbers of transactions, could pose challenges.The growing size of the blockchain with more users also suggests that ongoing costs and performance optimization will be crucial, especially for maintaining fast response times and managing network fees as presented in Fig. 6.
The ArchaeoMeta framework, while innovative and effective in a controlled environment, requires further optimization to handle large-scale deployments effectively.Future work will focus on refining transaction efficiency, perhaps through layer-2 scaling solutions or alternative consensus mechanisms that can offer quicker confirmations and reduced costs.The results indicated a linear increase in block size and gas usage as the number of users escalated as presented in Fig. 7.
