Chia (XCH) is a digital currency created by Bram Cohen, the founder of BitTorrent. It operates on a proof-of-space and time consensus mechanism, which aims to be more energy-efficient and environmentally friendly compared to traditional proof-of-work cryptocurrencies like Bitcoin. Users can “farm” Chia by allocating unused storage space on their computers. Chia has gained popularity for its unique approach to mining and its focus on sustainability in the cryptocurrency space.
