Chia (XCH) officially launched for trading on May 3, 2021, immediately capturing market attention. Its unique hard drive-based mining approach has driven increased demand for both HDDs (traditional hard drives) and SSDs (solid-state drives), significantly boosting prices of related stocks. This comprehensive guide explores Chia's technology, advantages, and why it's being called the "Green Bitcoin."
Understanding Chia (XCH)
Founded in August 2017 with the cryptocurrency code XCH (note: "Chia" is the name, not the ticker), Chia was created by Bram Cohen—the inventor of BitTorrent (BT download) and contributor to Steam's early code. Cohen's tech industry prominence helped Chia gain significant traction, securing approximately $16 million in funding since launch.
Unlike Bitcoin, Chia has no maximum supply cap, though it undergoes halving every three years. Its primary mission is to improve global financial and payment systems through its developing Chia Network, which aims to become the first enterprise-grade cryptocurrency.

Key Differentiators:
- No ICO plans—the team intends to take the company public in the U.S.
- Eco-friendly design using Proof of Space and Time (PoST) instead of energy-intensive Proof of Work (PoW)
What Is Proof of Space and Time (PoST)?
PoST combines two mechanisms:
Proof of Space (aka Proof of Capacity):
- Uses storage space instead of computational power
- Users allocate unused HDD space via plotting
- Mining probability = (Your provided space / Total network space)
- Example: 10TB allocated in a 100TB network = 10% block reward chance
Proof of Time:
- Uses Verifiable Delay Functions (VDFs) to synchronize blocks
- Requires just one efficient VDF server per blockchain
Consensus Mechanism Comparison:
| Type | Validation Criteria |
|---|---|
| PoW | Computer processing power |
| PoS | Coin ownership duration/amount |
| PoST | Provided hard drive space |
Chia's approach enables mining ("farming") with just HDD space and internet access—no expensive GPU rigs required.
Why "Farming" Instead of Mining?
Chia's terminology reflects its agricultural metaphor:
- Plotting: Preparing storage space (called "plowing" in China)
- Plots: Storage proof files (K32 plots require 340-350GB temp space)
- Farmers: Instead of miners
- Farming: Instead of mining
This terminology reinforces Chia's green energy positioning—its blockchain farming consumes minimal electricity (though SSD wear is a concern).
Is Chia Truly Eco-Friendly?
Energy Consumption
Chia claims "green money" status with:
- Estimated 8,993 kWh daily global usage (May 2021)—less than one American's annual consumption
- Compared to Bitcoin's 144.28 TWh yearly usage
Hardware Considerations
While energy-efficient, farming impacts hardware:
- SSDs: Consumer-grade models last just 30-160 days when plotting versus 8-10 years normal use
- HDDs: Minimal wear as storage devices; reusable if Chia adoption declines
Founder Bram Cohen recommends enterprise-grade SSDs for plotting to reduce e-waste. The network's storage capacity exceeded 7EB (7,340,032GB) within a month of launch.
Future Outlook
As a new cryptocurrency (trading at $986 at writing, with $2,500 ATH), Chia's long-term viability remains uncertain. Its success hinges on:
- Mainstream adoption beyond current listings (MEXC, OKX)
- Balancing eco-benefits with hardware sustainability
- Competing with Ethereum's upcoming PoS transition

FAQ
How does Chia farming differ from traditional mining?
Chia uses hard drive space instead of GPU/CPU power, making it more accessible but requiring significant storage.
What's the best hardware for Chia farming?
Enterprise SSDs for plotting + high-capacity HDDs for storage. Consumer SSDs wear out too quickly.
Will Chia replace Bitcoin?
Unlikely in the short term due to Bitcoin's first-mover advantage, but Chia positions itself as a sustainable alternative.
Where can I buy Chia (XCH)?
Currently on MEXC and OKEx. More exchanges may list as adoption grows.
Is Chia farming profitable?
Profitability depends on XCH price, network size, and hardware costs—calculate carefully before investing.
