OpenZeppelin Contracts provides AccessControl for implementing role-based access control. However, with this innovation comes the need to manage access control, which is where role-based access control (RBAC) comes in.

Smart contracts have been used to revolutionize the way transactions are performed on blockchain networks. In a system with a fixed number of roles, this can be achieved by querying the account for all known roles, but this doesn't work as well if dynamic roles are involved. 0) (access/IAccessControl.
