# Service Delivery PoC

Service Delivery PoC is based on two payment models:

* **aZen token burning**
* s**tablecoin payments**

### **aZen Token Burning Definition**: 

When clients burn aZen tokens to access services, node operators earn PoC based on the burned tokens.

### **Formula:**

$$
P\_S D=Burned,aZen,Tokens×C\_S D
$$

Where:

Burned aZen Tokens = Amount burned by clients. 

$$C\_SD$$ = Supply-demand-based coefficient.

### **Stablecoin Payment Definition**: 

If services are paid in stablecoins, a platform fee is converted into aZen tokens and burned to determine the PoC.

### **Formula:**

$$
P\_S D=Platform\~Fee×C\_S D
$$

Where:

Platform Fee = Portion of stablecoin payment converted to aZen tokens and burned (e.g., 5%). 

$$C\_SD$$ = Supply-demand-based coefficient.
