How Does Role-Based Access Control (RBAC) Improve Security over Single Ownership?

Role-Based Access Control (RBAC) improves security by assigning specific permissions to different roles (e.g. Admin, Pauser, Minter) rather than granting full, unrestricted power to a single owner.

Instead of a single address controlling everything, the contract logic only allows addresses with the 'Minter' role to mint tokens, or those with the 'Pauser' role to halt the contract. This compartmentalizes risk, ensuring that a compromise of one key only grants access to a limited set of functions, minimizing potential damage.
