Issue #8: Access Control & Permission System #211
Description
Description
Develop a comprehensive access control system with role-based permissions, modular access rights, and security features.
Tasks
- Create Role model with permission levels:
- role_id (u32)
- role_name (felt252)
- permissions (u256 bitmask)
- min_reputation_required (u256)
- Create UserRole mapping system
- Implement permission checking functions
- Build role assignment and revocation system
- Create admin role management
- Add emergency access controls
- Implement time-based permissions (temporary roles)
- Create permission inheritance system
- Add multi-signature requirements for critical operations
Acceptance Criteria
- Role-based permissions are properly enforced
- Admin functions require appropriate authorization
- Emergency controls can be activated when needed
- Temporary permissions expire correctly
- Multi-signature requirements work for critical operations
- Permission changes are properly logged
- System is resilient against privilege escalation attacks
