Many Trees. One currency.
Each qualifying mine is a separately identifiable Tree. The mines are not blended together as though all underground ounces were economically identical.
GFC remains the single principal currency of the system. Separate project coins are not required. Each Tree keeps its own technical identity, economic identity, legal identity, GFC participation and verification history.
As the number of qualifying Trees grows, the monetary foundation may become more diversified across mines, project stages and jurisdictions, reducing dependence upon any single mining asset.
