# Node Operators

### **Definition**: 

Rewards are distributed based on an operator’s proportion of total PoC in each category.

### **Formula:**

$$
T\_E=T\_C×I\_P/T\_P
$$

Where:

$$T\_E$$ = Tokens earned by the node operator. 

$$T\_C$$ = Total tokens allocated for the category. 

$$I\_P$$ = Individual PoC of the node operator. 

$$T\_P$$ = Total PoC generated in that category.

### **Coefficient Definitions:**

$$C\_N,C\_G,C\_C,C\_I:$$ Device-specific coefficients (Network, GPU, Computation, IoT). 

$$C\_D$$: Delegate coefficient (represents efficiency in delegation). 

$$C\_A$$: Aggregation coefficient (represents effectiveness in managing multiple devices). 

$$C\_DC$$: Data Center coefficient (specific for PoC within data centers).

$$C\_SD$$: Supply and demand coefficient (used for Service Delivery PoC).
