# Desktop (Full Core License required)

The Full Core License is required to operate a Datagram desktop node and participate fully in the earning structure of the Datagram Network. This license is ideal for users who want to earn from both node uptime and resource-sharing activities. It offers maximum earning potential within the system.

### License Activation & Duration

The Full Core License must be purchased after the testnet phase via an official Datagram node sale. Once purchased:

* The license is locked in your Datagram account wallet for **365 days**.
* After the lock-in period, it becomes **transferable**.

### Reward Eligibility

Holders of the Full Core License are eligible to earn from **50% of daily DGRAM emissions**, divided into

* **80% allocated to uptime rewards**
* **20% allocated to resource sharing rewards**

This means a Full Core node can earn rewards for both being online and actively sharing network resources.

### Uptime Reward Calculation

Uptime rewards are based on how long your node stays connected compared to total network uptime. The formula is:

{% hint style="warning" %}
(Your Node Uptime / Total Network Uptime) × 80% × 0.0625% of daily DGRAM emissions
{% endhint %}

This rewards users for consistently keeping their node online and contributing to network stability.

### Resource Sharing Rewards

The remaining **20% of the 0.0625%** of daily emissions is used for rewarding resource sharing:

* Datagram will calculate the value of shared services like **UDP**, **AI**, **TCP**, etc.
* That value will be swapped into DGRAM tokens and distributed to node operators accordingly.

If the shared rewards exceed the available daily allocation, the difference is covered using a **Special Rewards Pool**.

### Special Rewards Pool

Any unused resource-sharing rewards are transferred into a reserve pool. This pool is used when future daily emissions are not enough to cover the total rewards with Full Core License holders.
