# Nodes

### What Is a Node

A node is a key digital asset on hashed.farm that mines (generates) $HASH tokens when deployed to a datacenter. 

### Node Lifecycle

A node follows a clear lifecycle:

1. Built by selecting a tier and paying SOL
2. Deployed to a datacenter to begin mining
3. Deteriorates over time, reducing effective hashrate
4. Repaired or fused (upgraded) to maintain long-term value
5. Extracted to claim accumulated $HASH and redeploy to another datacenter for effectiveness.

Nodes that are **not** actively managed become less efficient over time.

### Node Tiers 

There are five tiers, each tier has 

* a randomized range of hashrate
* a chance to get a passive skill 

| **Node Tier** | **Build Cost (SOL)** | **Hashrate Range (MH/s)** | **Passive Skill Chance** |
| ------------- | -------------------- | ------------------------- | ------------------------ |
| Common        | 0.125                | 18–30                     | 25%                      |
| Uncommon      | 0.25                 | 40–65                     | 50%                      |
| Rare          | 0.5                  | 85–135                    | 75%                      |
| Ultra         | 1                    | 180–280                   | 100%                     |
| Superior      | 2                    | 370–590                   | 100%                     |

To build a node you need to have a corresponding amount of $SOL in your wallet. Make sure to deploy it to the datacenter, otherwise the node won’t generate the hashrate.
