The system shall provider a mechanism for Entities to delegate some functions to trusted Service Providers. Examples are the use of Identity Providers for proof of authorization, or the use of Storage Providers to keep data in Storages they own safe. Some interactions may require a trust relationship between Service Providers and Entities.

In general, this should not impede the ability of an Entity to operate or self-host a service. Also, trust relationship are not transitive, in the sense that if an Entity trusts a Service Provider, e.g. an Identity Provider, it does not follow that another Service Provider the Entity interacts with, e.g. a Storage Provider, is under any obligation to trust said Identity Provider.
