Abstract
Metaverse is the new virtual world that runs in parallel to the physical world. Multiple verses come together to form a large metaverse where various users, avatars, and devices communicate with one another using various technologies like AR, VR, XR, and MR. The traditional way of implementing these solutions is in a centralized way. Consequently, the authentication mechanisms used in the Metaverse are also centralized. The centralized nature of authentication has many limitations and is prone to authentication security threats. As users and avatars move across various verses in the metaverse, it becomes critical to have a decentralized mechanism for authentication. There are certain decentralized solutions proposed in the literature. But they come with their own limitations. Blockchain is a decentralized ledger technology that can provide an anonymous identity mechanism. In this paper, we propose a Blockchain-enabled architecture for the authentication of Avatars and users. This framework will ensure the decentralized authentication and traceability of the Avatar across the Metaverse. It will help in resolving security issues like impersonation, sever spoofing, identity interoperability, mutual authentication issues, replay, etc.
