# PoW（Edge Node）

**PoW Rewards**:

* A total of 350,000,000 $EX tokens will be allocated for PoW mining rewards.
* The number of tokens issued each quarter will decrease by 3%, with a total cycle of 16 years.

**Quarterly Token Release**

The number of tokens released each quarter (Qt) will be calculated using the following formula:

* Q0: Initial quarterly token release amount.
* r: Quarterly decrease rate (3%).
* t: Quarter number (starting from 0).

***

**Daily Token Release**

* The number of tokens released daily (Dd) will be calculated using the following formula:

* Qt: Current quarter’s token release amount.
* nd: Total number of days in the current quarter (e.g., 90 or 91 days).
* α: Dynamic adjustment coefficient, used to balance the daily release ratio.

***

**Introducing Dynamic Variables**

Introduce a dynamic variable **β**: β will be used to adjust the reward factor in real-time. Specific application scenarios include:

* **Network Load**: Increase the reward ratio during network peak times to encourage nodes to provide services at critical moments.
* **Node Performance**: Dynamically optimize rewards based on node performance metrics such as task success rate and response time.

***

**PoW Node Reward Distribution**

Daily token distribution will be based on node weight (w) and task completion (c) to ensure fairness:

* Ri: Token reward for node i.
* wi: Weight of node i.
* ci: Task completion rate of node i.
