“…The term Metaverse refers to next-generation Internet applications that aim to create virtual 3D environments where humans can interact with each other as well as the applications' functionalities via digital avatars [1]. Although the original concept dates back to 1992 [1], Metaverse has recently attracted paramount attention due to a huge potential for future Internet. Facebook has recently announced a $10 billion investment for Metaverse development, and at the same time, Microsoft has developed a Metaverse meeting framework [2].…”

“…To address the aforementioned challenges, blockchain has been considered to be a promising solution [1]. In particular, thanks to the smart contract mechanisms [10], blockchain can manage and automate complex interactions among various entities in Metaverse, such as Metaverse Service Providers (MSPs), users, and digital content creators.…”

“…Moreover, with outstanding benefits of immutability and transparency [8], blockchain can play a key role in ensuring data integrity and protecting digital assets in Metaverse applications. Furthermore, with the asymmetric key and digital signature mechanisms [8], blockchain can enhance the users' privacy and anonymity [1]. However, blockchain, especially when applied in Metaverse, also faces various challenges [1].…”

“…Furthermore, with the asymmetric key and digital signature mechanisms [8], blockchain can enhance the users' privacy and anonymity [1]. However, blockchain, especially when applied in Metaverse, also faces various challenges [1]. Particularly, most of the current blockchain networks have been employing the Proof-of-Work (PoW) [7] consensus mechanism which has a significant delay, e.g., Bitcoin requires roughly one hour to confirm a transaction [8].…”

Metaverse has recently attracted paramount attention due to its potential for future Internet. However, to fully realize such potential, Metaverse applications have to overcome various challenges such as massive resource demands, interoperability among applications, and security and privacy concerns. In this paper, we propose MetaChain, a novel blockchain-based framework to address emerging challenges for the development of Metaverse applications. In particular, by utilizing the smart contract mechanism, MetaChain can effectively manage and automate complex interactions among the Metaverse Service Provider (MSP) and the Metaverse users (MUs). In addition, to allow the MSP to efficiently allocate its resources for Metaverse applications and MUs' demands, we design a novel sharding scheme to improve the underlying blockchain's scalability. Moreover, to leverage MUs' resources as well as to attract more MUs to support Metaverse operations, we develop an incentive mechanism using the Stackelberg game theory that rewards MUs' contributions to the Metaverse. Through numerical experiments, we clearly show the impacts of the MUs' behaviors and how the incentive mechanism can attract more MUs and resources to the Metaverse.

“…With the continually improving device hardware and the upgraded network capabilities brought by 5G, companies envision the development of large-scale XR environments. From the Niantic planet-scale AR alliance 1 to Facebook's metaverse, major industry actors envision the future of XR as pervasive, shared, and permanent environments where digital and physical are closely interleaved [20].…”

Driven by the recent improvements in device and networks capabilities, Extended Reality (XR) is becoming more pervasive; industry and academia alike envision ambitious projects such as the metaverse. However, XR is still limited by the current architecture of mobile systems. This paper makes the case for an XR-specific operating system (XROS). Such an XROS integrates hardware-support, computer vision algorithms, and XR-specific networking as the primitives supporting XR technology. These primitives represent the physicaldigital world as a single shared resource among applications. Such an XROS allows for the development of coherent and system-wide interaction and display methods, systematic privacy preservation on sensor data, and performance improvement while simplifying application development.

We present two digital-based educative games aiming to engage students and the general public with battery sciences. The first one is a multiscale simulator in Mixed Reality of a battery-powered Electric Vehicle (EV) interacting with an Electrical Grid. One of the players drives the EV in a Virtual Reality (VR) environment where the EV can be recharged, and the other players control the electricity produced, distributed, consumed and stored by interacting with 3D-printed devices.
