What is Chia?
Chia is a new cryptocurrency that works on hard-drives.
Instead of mining, Chia uses plots.
Plotting is how hard drives are added to the network. Plotting requires high end equipment and can take a long time. Once plots are created, they are farmed. Farmers process information on their hard-drives and get rewarded in Chia's Token (XCH). The more space farmed on, the higher chance of receiving a Token.
