Today your data has to travel to whoever wants to use it. Once it leaves, you have no say in where it goes next.
Freehold turns that around. Your data stays where it is. The question comes to it, the calculation happens there, and only the answer leaves, carrying a label that says where it came from and what it may be used for.
That is what the name means. A freehold is land you hold outright, owing nothing to anyone. You sell what it produces. The ground stays yours.
You trade the harvest, not the field.
