# Node Deterioration & Repair

Hashed simulated the way equipment works. Nodes can deteriorate with time and slowly lose crumbles of power after repairs.

#### Power Deterioration

While a node is deployed in a datacenter, **it experiences constant wear!**

Nodes lose power at a base rate of <mark style="color:green;">1% per hour while active.</mark> This loss directly reduces the node's effective hashrate for mining (rewards as well.)&#x20;

{% hint style="danger" %}
**To ensure a node always contributes some value, power cannot drop below a minimum floor of 25% of its base power.**
{% endhint %}

[The Deterioration Reducer passive skill](https://docs.hashed.tech/core-concepts/passive-skills) can lower this hourly decay rate based on the skill's specific percentage.

### Automatic Extraction Rules

The system enforces a "maintenance minimum" to prevent nodes from running at critically low efficiency.

If a deployed node's power drops below 25%, it is automatically extracted from the datacenter and accumulated $HASHED are sent to the wallet (minus the 10% penalty fee).

### Repair System Overview

Nodes require repairs to restore their effective hashrate to 100%.

Repairing a node that is not deployed is free.&#x20;

Any $HASH spent on repairs is auto burned, helping to regulate the token supply.

**Repair Cost Formula**

For nodes currently deployed, the repair cost is tied to your unclaimed rewards, it will be shown before transaction.

***Example***

If power is 60% (0.6), missing power is 40%, so 40 units. Cost = 0.01 × 40 × unclaimed = 40% of unclaimed rewards.

• Formula: `repairCost = unclaimedRewards × 0.01 × missingPowerUnit`s.

• Calculation: `missingPowerUnits` is defined as the percentage of power lost divided by 0.01 (e.g., 30% lost = 30 units).

### Permanent Hashrate Degradation

Repairing a node is not a perfect restoration, it causes permanent structural damage to the node's base hashrate.

A node permanently loses 1% of its base hashrate for every 100% of power restored.

• Degradation Formula: `newBaseHashrate = oldBaseHashrate × (1 - powerRepaired × 0.01)`

• Cumulative Effect: This degradation accumulates over time.&#x20;

***Example***

If you repeatedly let a 100 MH/s node drop to 25% and repair it, its base hashrate will drop to approximately 99.25 MH/s after the first repair and roughly 8.3 MH/s after ten such repairs.

> Managing deterioration is vital for maintaining a profitable mining operation over the long term.

#### Tips:&#x20;

Repairing when power is still high (e.g., above 80%) results in smaller degradation per repair, preserving more of the node's absolute hashrate value for a longer period.

Strategic players use [Deterioration Reducer skills](https://docs.hashed.tech/core-concepts/passive-skills) or [Flux Expanders](https://docs.hashed.tech/core-concepts/items-and-inventory) to add maintenance-related skills, minimizing repair frequency.

*Because nodes eventually lose value through degradation, there is a natural demand to build new nodes or use the Fusion system to replace older, less efficient hardware.*
