“…In terms of personal finance, possible use cases for the metaverse include lending, borrowing, saving and investment in the virtual world. The authors in [55] proposed an architecture using Hyperledger Fabric as a trusted service to enhance the reliability and security of the peer-to-peer lending process. While loan transactions are collected and submitted to the blockchain network by Order nodes, smart contracts regulate the registration process, making it automatic with trust establishment.…”

Envisioned to be the next-generation Internet, the metaverse has been attracting enormous attention from both the academia and industry. The metaverse can be viewed as a 3D immersive virtual world, where people use Augmented/Virtual Reality (AR/VR) devices to access and interact with others through digital avatars. While early versions of the metaverse exist in several Massively Multiplayer Online (MMO) games, the full-flesh metaverse is expected to be more complex and enabled by various advanced technologies. Blockchain is one of the crucial technologies that could revolutionize the metaverse to become a decentralized and democratic virtual society with its own economic and governance system. Realizing the importance of blockchain for the metaverse, our goal in this paper is to provide a comprehensive survey that clarifies the role of blockchain in the metaverse including in-depth analysis of digital asset management. To this end, we discuss how blockchain can enable the metaverse from different perspectives, ranging from user applications to virtual services and the blockchain-enabled economic system. Furthermore, we describe how blockchain can shape the metaverse from the system perspective, including various solutions for the decentralized governance system and data management. The potential of blockchain for security and privacy aspects of the metaverse infrastructure is also figured out, while a full flow of blockchain-based digital asset management for the metaverse is investigated. Finally, we discuss a wide range of open challenges of the blockchain-empowered metaverse.

“…Therefore, all nodes in the blockchain system jointly maintain the data information, which ensures the consistency and integrity of the data. At present, according to different application scenarios, blockchains are divided into three categories: public blockchain, private blockchain, and consortium blockchain [18] . The public chain is open to all nodes, and each node is equal.…”

The existing research on the Internet of Vehicles (IoV) based on blockchain adopts the single chain mode. However, in the face of large-scale data environment, it is difficult to ensure the security and efficiency of large-scale data storage by using single chain. Thus, this paper is devoted to the research on the master-slave multi-chain IoV architecture. In the proposed architecture, there are two major innovations: 1) By defining three different data structures, micro-block, key-block and verification-block, the master-slave multi-chain model based on hash anchoring is designed to break through the data of the whole network. It ensures the consistency and integrity of IoV data, and solves the problem of privacy disclosure caused by insecure data storage; 2) A data upload and access mechanism based on attribute encryption is designed between users and RSU nodes. It solves the problem of privacy disclosure caused by insecure transmission outside the data chain. Finally, we verify that the proposed architecture is more suitable for large-scale data scenario by simulation analysis of system response time and encryption/decryption overhead.

“…(1) Preparation stage. After the client sends the transaction to the master node [5] , the node generates a pre-prepared message according to the transaction request and broadcasts it to each slave node, the message content is 𝑃𝑅𝐸 𝑃𝑅𝐸𝑃𝐴𝑅𝐸, 𝑣, 𝑛, 𝑑 _𝑠, 𝑚 . Where 𝑣 is the view in which the message is sent, _𝑠 is the signature, and m is the client Request message at the end, 𝑑 is the summary of 𝑚.…”
