Exchange Hubs and their functionalities

An exchange hub is an entity available on the asset's (and therefore byteball) network whose responsibility is to provide bytes (necessary for creating new transactions) to asset's clients who need or require them. Funding hubs:

• Hubs work as an exchange office: they propose to exchange assets for bytes at a certain rate

•They work, similarly to witnesses, independently from each other in a way that anyone can has the possibility to become a hub. Potentially any client has this possibility.

• Their service can't be centralized or controller completely by anyone

• Offer exchange rates: client may choose the best offer.
