## 4 Proposed Framework
### Simulation  
Figure 3 shows our simulation of a primarily Self-Sovereign Identity (SSI)-based authentication system for the Metaverse using Hyperledger Aries. The process follows in the following sequence.  
* **Setting Up the Simulation Environment** First, we install Git, Python, and Docker. In containerized environments, Docker is essential for navigating Hyperledger Aries and streamlining the setup and deployment process. Next, we use Git to clone the essential Hyperledger Aries repositories. The hardware and scripts required for our simulation are contained in these repositories.
* **Launching Aries Agents** Docker Compose, which is found inside the cloned repositories, is used to launch multiple Aries sellers. Within the SSI version, each agent represents a unique entity, such as an identity holder, issuer, or verifier. We set each agent up to perform specific tasks within the SSI environment. For example, one agent acts on behalf of the identity company, another acts as the verifier, and a third represents an individual within the Metaverse.
* **Simulating SSI Scenarios** Using the issuer agent and their attractiveness via the user agent, we simulate the issuance of digital credentials. This is an essential step in verifying the credential issuance procedure within the Metaverse. The integrity and validity of the SSI model are then confirmed through testing the verification process of these credentials with the help of the verifier agent. Furthermore, we replicate credential revocation and confirm that the verifier agent can properly encounter and handle revoked credentials.
* **Integration with the Metaverse** We combine the Aries retailers to control authentication inside a digital environment (such as one created in Unity or Unreal Engine)

for the Metaverse. Through APIs or SDKs, this integration makes it possible for the Metaverse utility and the Aries dealers to communicate with one another.
* **Development and Testing** We expand custom scripts or applications that utilize Aries dealers to model accurate interactions in the Metaverse, specifically designed to meet the requirements of the SSI version. The marketers are controlled programmatically by the Hyperledger Aries APIs, which replicate different SSI operations relevant to the Metaverse.
* **Performance Monitoring and Analysis** To gain insight into the SSI interactions and transactions, we monitor the Aries sellers' logs and outputs throughout the simulation. The scalability and efficiency of the SSI version in a Metaverse environment are assessed using key performance metrics like response time, throughput, and aid utilization.
* **Utilizing Community Resources** We refer to the Hyperledger Aries documentation when looking for exact instructions and best practices. Part of our strategy involves interacting with the Hyperledger community, especially for troubleshooting and obtaining insights unique to the current state of the Metaverse.  
Through this comprehensive setup and simulation technique, we aim to comprehensively check and validate the SSI-based total authentication model for the Metaverse, making sure it meets the necessary requirements for security, scalability, and personal experience.
