• Decentralized ownership

Thoughts from earlier about ownership: dFed participant vs. dFed provider.

The terminology here is complex and needs to be elegantly delivered otherwise it will be totally lost on the reader.

In my head dFed participants take part in the formulation of the dFed. That is, they select which providers to include, what the workflows are, what tasks and objectives are a priority. They choose the providers.

The dFed providers expose their services for inclusion in a workflow. Providers also have concerns for things like QoS and security and availability, but we refer to those as contracts to delineate the difference from the participant concerns. Contracts are enforceable (they are being adhered to or not), participant concerns may not be so clearcut.

With that mindset dFed participants own the federation, and dFed providers own the services. Of course there are exceptions. For example, a specific type of service may only be exposed to the dFed (its a secret or a time-sensitive service only available for a crisis). It's still owned by a specific provider, but its created for the dFed participants.
