## 4 Proposed Framework
These VCs are given to users, who keep complete control over who can access them by storing them in their Identity Wallet. * Authentication Request: The service provider asks for authentication when a user wants to use a service inside the Metaverse. The credentials that are needed to gain access are listed in this request (e.g., age verification and membership status). The request reaches the user's Identity Wallet, which asks for permission to share particular VCs. * Consent and Privacy Management: Users can examine the authentication request and decide which credentials to share using the Identity Wallet as a Consent Layer. Users have the option to divulge only the information required to complete the transaction. By using zero-knowledge proofs, the framework enables users to validate identity claims without disclosing the actual credentials. * End-to-end Encryption: Every exchange of credentials and personal data within the framework, in particular, is end-to-end encrypted. This prevents information from being intercepted or accessed by unauthorized parties because only the intended recipient can decrypt and view the data. * Zero-Knowledge Proofs: A party can prove to another that a statement is true without revealing any information except that the statement is true by employing cryptography. Within the framework of SSI, it permits users to authenticate themselves or certain aspects of their identity without disclosing their personal information. * Blockchain Technology: A decentralized, unchangeable ledger is made possible by using blockchain technology to record DIDs and VCs. This stops historical records from being altered or tampered with, in addition to guaranteeing the authenticity and non-repudiation of the identity data. * Minimising Data and Obtaining Consent: The framework processes personal data only to the extent necessary for the specific purpose for which the user has granted consent, in accordance with the data minimization principle. Users are guaranteed fine-grained control over what data they share and with whom thanks to the Consent Layer. * Anonymity and Pseudonymity: Pseudonyms are a convenient way for users to communicate in the Metaverse without having to reveal their true identities. This makes it possible to engage in digital activities while protecting one's privacy. **Interoperability and Standardization:** The framework conforms to the World Wide Web Consortium's (W3C) global standards for DIDs and VCs in order to guarantee a seamless user experience throughout the Metaverse. Open protocols and APIs make it simple for service providers to be integrated. Cross-chain interoperability is present to enable DIDs and VC verification between various blockchain networks governed by international laws. Standardization and interoperability are essential to the SSI framework's functionality and broad acceptance across various Metaverse platforms. The following measures are proposed:
* Adherence to W3C Standards: The framework will be developed in accordance with the standards for DIDs and VCs set forth by the World Wide Web Consortium (W3C), guaranteeing a standardized and open model for digital identities that is suitable for widespread adoption. * Open APIs and Protocols: The framework makes it simple for different service providers to integrate with the Metaverse by offering open APIs and standardized protocols, which promotes a consistent user experience across platforms and services. * Cross-Chain Compatibility: Cross-chain interoperability will be supported by the framework, making it possible to verify DIDs and VCs between various blockchain networks. This guarantees that users, irrespective of the blockchain technology utilized, can preserve a singular identity on various platforms. **Governance and Evolution** The framework will be governed by a decentralized autonomous organization (DAO), in which decision-making will involve participation from stakeholders from all over the Metaverse. The development of protocols and standards will be supervised by the DAO.
