# 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
