Verify the authenticity of a user's identity: This operation ensures that a user is who they claim to be by requiring them to provide valid identification credentials, such as a username and password, during the login process.↵↵2. Confirm the user's authority to access specific resources: After verifying the user's identity, the AuthenticateCapability operation checks if the user has the necessary permissions to access certain resources on the blockchain network. This helps maintain security and prevent unauthorized access to sensitive information or functions.↵↵3. Secure communication between nodes: By authenticating a user's identity, this operation enables secure communication between nodes (peers) in the blockchain network. This is crucial for maintaining the integrity and privacy of the data exchanged between nodes.↵↵4.
