# Proof of Contribution (PoC)

The Proof of Contribution (PoC) is the mechanism aZen rewards Suppliers for supplying Computation Resources.

The aZen DePIN PoC algorithm is structured to optimize decentralized infrastructure participation by:

* Rewarding **uptime** and **quality** of computing resources.
* Encouraging **delegation**, **aggregation**, and **data center operations** for better resource utilization.
* Enabling flexible service payments via **token burning** or **stablecoin** payments.
* Ensuring a **transparent** and **fair distribution of rewards** based on real contributions.
