Chia Network is a blockchain platform utilizing a combination of proof of space and proof-of-time mechanisms to issue its digital currency known as Chia (XCH). Established in 2017 by Bram Cohen, the creator of BitTorrent, along with Ryan Singer, the company is based in South San Francisco, California.
History
In 2017, Bram Cohen and Ryan Singer co-established Chia Network. Cohen's objective was to tackle the environmental concerns linked to cryptocurrency mining, especially the substantial energy consumption involved in bitcoin mining, by leveraging unused hard disk capacity rather than relying on the energy-heavy proof of work system. The blockchain is developed using Chialisp, the firm’s proprietary programming language.
During 2018, Chia Network secured $3.4 million through seed investment. By April 2019, a beta release of its blockchain and XCH token was made available to developers. The network expanded to approximately 1,700 nodes by late 2020. After raising $61 million in early 2021, the company’s valuation reached $500 million, attracting investors such as Andreessen Horowitz, Naval Ravikant, and Breyer Capital.
By 2021, participants had dedicated nearly 40 billion gigabytes of storage to support Chia's network. Rather than conducting an initial coin offering, Chia Network opted for venture capital funding while retaining pre-farmed tokens. The company revealed intentions for either a conventional IPO or merging via a special-purpose acquisition company. When XCH commenced trading on May 3, 2021, Chia held a reserve of 21 million tokens. This token launch spurred heightened demand and price increases for hard disk drives (HDDs) and solid-state drives (SSDs).
In April 2023, Chia Network submitted a draft registration statement with the U.S. Securities and Exchange Commission, indicating advancement toward an initial public offering.
Ahead of Chia’s launch in May 2021, surging demand for storage devices led to shortages and price hikes for HDDs and SSDs, particularly affecting markets in China and Vietnam. Seagate, a leading manufacturer, reported robust order volumes and efforts to fulfill demand. Gene Hoffman, serving as president at that time and now CEO, acknowledged that short-term hard drive supply chains experienced disruption.
Concerns emerged regarding the plotting method in Chia farming significantly shortening SSD lifespan. By late 2024 and early 2025, incidents were reported involving fraudulent resale of used hard drives marketed as new; investigations linked these activities to Chia farms which had reportedly shut down due to diminishing profitability in Chia mining.
Chia token
The native cryptocurrency of Chia Network is the Chia (XCH) token. Instead of utilizing computational power like proof of work cryptocurrencies such as Bitcoin, users contribute unused storage capacity from their devices to maintain the blockchain through a combined proof-of-space-and-time consensus mechanism. This procedure, referred to as "farming," incentivizes participants with XCH rewards.
Partnerships
In August 2022, the International Finance Corporation collaborated with Chia Network, Aspiration, Inc., and Cultivo to establish a fund dedicated to tokenizing and monitoring carbon offset initiatives. Additionally, Chia supports the Climate Action Data Trust—a joint effort involving the International Emissions Trading Association, World Bank, and the Government of Singapore—which aims to enhance transparency and integrity within carbon markets.
