Can you make clear the role of decentralized technology in Metaverse? What is the critical feature that Blockchain can provide?
Sir, here we are discuss how blockchain is applied in the metaverse.
A. Data storage: - In the metaverse, various kinds of user data are digitized, collected, and stored. How to store such a massive amount of data is a crucial problem. Traditional data storage systems usually adopt the centralized architecture, which requires transmitting all data to a data center. Considering such amount of data, extremely high storage capacity is essential, which is usually very expensive. Moreover, sensitive information may be included in such data, which may lead to potential privacy leakage issues. Blockchain, as a distributed database is just enough to handle sensitive data issues and IPFS could be used to store the non-sensitive data. Users with blockchains can create data blocks and validate and record transactions cooperatively. A distributive personal data management system based on blockchain. There is a secure channel for data accessing. The data owner shares a key with all other users requesting the data. The authentication of requesters is done through blockchain, which guarantees the security of the data.
B. Data sharing: - Blockchain-based data storage systems are of high scalability and flexibility. Metaverse users contribute their storage resources in blockchains. Each user could be both a data requester and a data provider. Moreover, the data is encrypted and relocated to an anonymous node for storage, further enhancing data security. All nodes in blockchains record the data location. Thus, data owners can access their data very conveniently.
C. Data interoperability: - Privacy and security are of utmost importance for managing the data in the metaverse. However, it is inevitable to access and operate on such data by multiple parties. Consequently, conflicts occur. Blockchain provides a data platform with extremely high security, enabling different companies to share data. For example, banks and insurance companies can share the same customer data for their separate business through blockchain for interoperability. A typical application scenario of blockchain on data interoperability is smart healthcare. Digital twins would be created for patients based on their profile data for precise healthcare. Such digital twins could be accessed by multiple doctors. Some literatures have proved the feasibility of applying distributed ledgers to storing patients’ information from a theoretical aspect.
