Everything you need to know about Chia and how to farm it

Cryptocurrency is a love and hate relationship with the big coins (Bitcoin and Ethereum) receiving flak for high energy demand and GPU shortages, but the technology of blockchains is still incredible and has a bright future. There are countless other cryptocurrencies, but a new one called Chia could change things with the environment in mind.

What is Chia?

Chia is a new cryptocurrency that, unlike Bitcoin and Ethereum, doesn’t use Proof of Work (PoW) for mining new coins. Instead, Chia utilizes what’s known as Proof of Space and Time (PoST). Instead of requiring beefy computers or the best graphics cards to solve calculations, Chia requires empty hard drives to “farm” the cryptocurrency with minimal resources.

The blockchain was created by Bram Cohen, one of the founders of BitTorrent and the brain behind the entire concept of peer-to-peer torrents. Proof of Space is a cryptographic technique that requires unused hard disk space to be used with the Proof of Time, which together ensures that block times have consistency in the time between them and increases the overall security of the blockchain.

This is but a simplistic explanation of this particular blockchain technology. I’d highly recommend reading the FAQ on the official website.

How to farm Chia

You notice we use the term farm and not mine, which is representative of what we’re actually doing here and sets it apart from dirty methods used for Bitcoin. In order to farm Chia, we need to prove (Proof of Space) that we’re dedicating storage space to Chia by downloading and installing software to seed unused storage space. A collection of cryptographic numbers will be stored, called “plots.”

Instead of miners, we’ll be called “farmers.” When the blockchain broadcasts a challenge for the next block, farmers will earn a reward if they have a hash that is closest to the challenge in a plot. A farmer’s probability of winning a block is the percentage of the total space that a farmer has compared to the entire network. The more plots, the higher the probability.

You can check how much you’ll earn farming Chia using this Chia Calculator. To start farming, you’ll need a Windows PC with an SSD — macOS and Linux are also supported.

  1. Visit the Chia website.
  2. Click on “Install Chia Blockchain“.
  3. Scroll down to the Windows version and download the Chia Blockchain for Windows.
  4. Install and run Chia Blockchain.
  5. Click on “Create a new private key.” (Write down the provided 24-word mnemonic. You’ll need this to recover your wallet and Chia.)
  6. Click on “Plots.”

  7. Click “Add a Plot.”
  8. Fill out the necessary information (k=32 is pretty safe with the below PC build).
  9. Wait for the plots to be filled in.
  10. Profit.

The Temporary Directory is where storage is temporarily used to write a plot file. Once this has been written, it’s moved to the Final Directory, and the temporary Directory space is freed up for the next plot. The Final Directory is where the plot files come to rest until deleted. These are constantly farmed for new coin rewards until removed from the farm.

Recommended PC builds

A good Chia farm needs all the usual PC parts. The Temporary Directory, which is where your plots will be filled in, will need to be a capable SSD. Using anything less will be slow or likely fail. You can use SSDs or HDDs for the Final Destination plot drives; however, these will need to be considerable in size. I’d go with hard drives unless you have the spare cash for expensive flash storage.

I’ve put together a build that will serve you well for starting out with Chia farming, but really you can just use your Windows 10 PC.

So long as you have a decent processor, plenty of RAM, and a very good SSD, you should be good to go with nothing but your gaming PC. Simply buy an expansive set of HDDs and you’ll be ready to farm some Chia.
