# Emission Schedule & Decay Model

DNAi adopts a **gradual emission model with predefined decay**, designed to balance early participation incentives with long-term sustainability and scarcity.

All token issuance originates exclusively from the **Health Data Mining Reserve**, which accounts for **70% of the total $DNAi supply**. No additional minting channels exist.

#### **Annual Emission Framework**

The protocol enforces a **hard annual emission cap**, calculated as a percentage of the remaining mining reserve.

* **Initial annual emission rate:** 10%
* **Annual decay factor:** 0.90
* **Formula:** Year *N* emission = Mining Reserve × 10% × (0.90)^(N − 1)

This ensures that token issuance decreases predictably over time, preventing excessive dilution while preserving incentives for early contributors.

#### **Epoch-Based Distribution**

Each annual emission amount is evenly distributed across **weekly epochs**, creating a transparent and continuous issuance schedule.

* **Epoch length:** 7 days
* **Epoch reward pool:** Annual emission ÷ 52
* **Distribution rule:** Each participant receives a proportional share based on their **Credit contribution relative to total network Credit during that epoch**

This design allows issuance to respond dynamically to real participation rather than fixed allocations.

#### **Claim Mechanism**

Epoch rewards require an **active user claiming**.

* Rewards become claimable at the end of each epoch
* **Unclaimed rewards are not burned, redistributed, or reassigned**
* Unclaimed tokens remain permanently in the public reward pool address, preserving supply integrity and transparency

This mechanism prevents forced distribution and ensures that only engaged participants receive rewards.

#### **Design Rationale**

The emission and decay model is designed to:

* Encourage early participation without exhausting long-term incentives
* Align token issuance with real, verifiable health data contributions
* Maintain a predictable monetary policy for long-term ecosystem participants
* Avoid sudden supply shocks or discretionary minting

By combining **epoch-based distribution** with a **declining emission curve**, DNAi establishes a sustainable incentive framework that supports continuous network growth while reinforcing long-term scarcity.
