# Mining CryptoCash

Anyone can mine for CryptoCash by sending a `mine` transaction to the CryptoCash smart contract on the Stacks blockchain.

There are no hardware requirements and the protocol is open source, so anyone can build a web app/site that interacts with it.

{% hint style="warning" %}
**Miners can only participate once per block.** 
{% endhint %}

{% hint style="warning" %}
**Once STX is sent for mining CryptoCash, it is not returned.**\
\[STX is distributed to CryptoCash Stackers(95%) & Foundation (5%)**.**]
{% endhint %}

## **How it Works**

CryptoCash miners spend STX while competing to earn the CryptoCash block reward, which follows are halving emission schedule and begins at 3,200 CryptoCash per block.

* 95% of the STX that miners spend is are distributed to the people who Stacked their CryptoCash (Stackers)
* 5% of the STX that miners spend is sent directly the Foundation wallet.

{% hint style="warning" %}
**There is only one winning Miner per block that can claim the CryptoCash reward.**
