# Start Node

{% hint style="warning" %}
The Overwatch Node documentation is under construction. Stay tuned for more information!
{% endhint %}

To start an **Overwatch Node**, you must be a trusted participant in the network.

Each coldkey in the Hypertensor network has its reputation tracked on-chain based on its subnet validator node activity.

#### To become an Overwatch Node:

* **Your coldkey's reputation must:**
  * Have the **minimum required reputation weight**
  * Have a **minimum age in the network**
  * Have the **minimum average attestation ratio**
* **Must be diversified:**
  * For example, an Overwatch Node **must be an active subnet in a minimum of 51% of the total subnets** in the network.
  * This ensures each Overwatch Node wants the **success of the overall network** and not just specific subnets.

***

### The reputation of a coldkey uses multiple factors:

#### Start Epoch

The epoch when the node was first elected subnet validator node to submit consensus. 

#### Weight

Current reputation weight, i.e., the score of the coldkey.

#### Lifetime Node Count

Track total nodes under a coldkey ever; this can only increase.

#### Total Active Nodes

Track total nodes under a coldkey.

#### Total Increases

Number of times the node's weight increased (i.e., successful validation).

#### Total Decreases

Number of times the node's weight decreased (i.e., failed validation).

#### Average Attestation

The average attestation rate across all subnets when the elected validator.

#### Last Validator Epoch

The most recent epoch the node was elected as the validator.
