Chia (XCH)

Overview

Chia is a public blockchain with a native coin called XCH. People can send XCH, use it to pay network fees, and build applications that record and move digital assets. The network is best known for proof of space and time. Instead of competing through constant, intensive computing, participants called farmers dedicate storage space and check it for answers to the network’s challenges. A separate process proves that time has passed between steps in the chain. (docs.chia.net)

Chia also supports programmable transactions. Its design brings together a payment coin, a way to issue other assets, and tools for exchanging them. Understanding XCH therefore means looking at both the farming system that secures the chain and the applications built on top of it. (docs.chia.net)

History & Team

From BitTorrent to Chia

Bram Cohen, the inventor of the BitTorrent file-sharing protocol, founded Chia Network in 2017. The company develops software and services around the public Chia blockchain. Mainnet began on March 19, 2021. At first, farmers could earn rewards; transactions and Chialisp features followed in May 2021. (chia.net)

Cohen serves as chairman and chief technology officer. Gene Hoffman is the company’s chief executive officer and president. Chia Network has raised money by selling company equity to investors, including Richmond Global Ventures, a16z Crypto, Slow Ventures, Naval Ravikant, and Breyer Capital. Those investments helped fund the company’s development work; company shares and XCH are different assets. (chia.net)

Technology & How It Works

Farming with storage space

A farmer first creates files called plots. Plotting fills storage with data prepared for Chia’s proof-of-space system. Once a plot is made, it can be checked repeatedly as the network produces new challenges. A farmer whose plot contains a qualifying proof can propose a block and earn a reward. In broad terms, a farmer’s chance of finding a proof grows with the share of eligible storage they contribute. (docs.chia.net)

The “time” part uses verifiable delay functions, or VDFs. Computers called timelords carry out calculations that take time to finish but are quick for others to check. The network combines these proofs of elapsed time with farmers’ proofs of stored space to order blocks. Full nodes then check blocks and transactions against the chain’s rules. (docs.chia.net)

Farmers can work alone or join a pool. Pool members submit smaller proofs to show the storage they contribute and receive portions of rewards when their pool wins. Chia’s pooling system lets a farmer with portable plots change pools through a blockchain object called a plot NFT. The farmer who finds a winning proof still creates the block. (docs.chia.net)

Programmable coins

Chia records ownership through a coin-set model, similar to the unspent-output model used by Bitcoin. Each coin has rules governing how it can be spent. Developers write these rules as programs called puzzles in Chialisp. When a coin is spent, a valid solution satisfies its puzzle, and the transaction can create new coins. This structure supports ordinary transfers as well as more detailed conditions, such as releasing funds after a set time. (docs.chia.net)

Tokenomics & Utility

XCH pays transaction fees and rewards farmers who help secure the network. Its smallest unit is a mojo; one XCH contains one trillion mojos. A reward is divided into two parts: one-eighth goes directly to the farmer who finds the block, while seven-eighths goes to that farmer or, for pooled plots, to the pool for distribution. Farmers also receive the fees attached to transactions in the blocks they produce. (docs.chia.net)

At launch, Chia Network created 21 million XCH as a company-controlled strategic reserve, often called the pre-farm. Coins earned through farming follow a separate issuance schedule. The block reward began at 2 XCH, fell to 1 XCH after the first halving, and is designed to halve every three years for four halvings in total. After that, the schedule continues at 0.125 XCH per block. These changes occur at specified block heights, so calendar dates are estimates. (docs.chia.net)

The reserve makes the company’s decisions about its use an important part of Chia’s economic model. Meanwhile, continuing farming rewards provide an incentive for people to maintain plots and participate in block production. XCH also serves as the native asset people can transfer or exchange for assets issued on Chia. (chia.net)

Ecosystem & Use Cases

Assets, trades, and records

Developers can issue Chia Asset Tokens, or CATs, using the network’s programmable coin rules. These tokens can represent digital assets with their own terms. Chia also supports non-fungible tokens, which can be used to record ownership of distinct items. An Offer lets one person propose an exchange of assets that settles together when another person accepts it. This gives applications a way to arrange trades directly on the blockchain. (docs.chia.net)

Chia’s tools have uses beyond transfers. The Climate Action Data Trust uses Chia’s Data Layer to help connect carbon-credit registry information. Participating organizations keep their data locally, while proofs recorded on the blockchain help others check that shared records match. Chia has also reported carbon-credit tokenization and retirement transactions on its chain. These are examples of how the network can support records as well as digital assets.

Financial applications are another area of development. In 2026, Permuto introduced a production platform built on Chia for a type of volatility-based financial contract. Together with CATs, NFTs, and Offers, such projects show the range of applications that can use Chia’s programming tools. They do not all use XCH in the same way: some rely on it for fees, while others also use it in transactions. (chia.net)

Advantages & Challenges

Proof of space allows a farmer to reuse a plot rather than perform a new round of intensive computation for every challenge. Plots can be kept on hard drives, and farming generally involves checking them as challenges arrive. Chia’s pool design also gives smaller farmers a way to receive portions of rewards more regularly than they might when farming alone. (docs.chia.net)

Creating plots takes computing resources and can involve substantial temporary disk writes. Repeated plotting can wear consumer SSDs, while a finished plot has a different, lighter workload during farming. Storage capacity, hardware costs, and the time needed to create plots all shape participation. Small solo farms can also wait a long time between block wins. On the application side, developers must learn Chia’s coin-set model and Chialisp to make full use of the network. (docs.chia.net)

Where to Buy & Wallets

XCH is available on exchanges including OKX, KuCoin, and MEXC. Availability depends on the exchange and the user’s location. Chia’s own Cloud Wallet also supports XCH purchases through eligible U.S. bank accounts using ACH transfers. (okx.com)

The Chia Cloud Wallet is a web-based wallet used with Chia Signer. The downloadable Chia App includes a wallet alongside tools for running a node and farming. Both provide ways to manage XCH on its native blockchain. Wallet choice often comes down to whether a person wants a web-based way to transact or software for local network participation. (chia.net)

Regulatory & Compliance

Chia Network has stated that it seeks to operate within financial rules and has submitted a confidential draft registration statement for a proposed public offering of company stock in the United States. Rules affecting XCH transactions, exchanges, and services depend on the activity and jurisdiction. In the United States, the Internal Revenue Service applies property-tax principles to digital assets. In the European Union, the Markets in Crypto-Assets framework sets rules for crypto-asset activities and service providers. (chia.net)

Islamic-finance treatment calls for attention to both the asset and the transaction. Malaysia’s Securities Commission Shariah Advisory Council recognizes that certain digital assets can qualify as assets under Shariah and sets conditions for permissible investment and trading within its regulatory scope. For XCH, a direct transfer, an exchange, and a financial contract built on Chia can raise different questions about how each arrangement works. The Council’s framework does not give every cryptocurrency a single, automatic halal classification. (sc.com.my)

Future Outlook

Chia’s development work continues across its core protocol, wallets, and application tools. One proposed change is a new proof-of-space format called Proof of Space 2, intended for Chia 3.0. Chia Network has described it as a way to tie farming more closely to storage actually used and to phase out the original plot format after activation. The proposal includes a transition in which continuing farmers would create new plots. (chia.net)

The network’s longer-term role will also depend on what people build and use: asset exchanges, financial tools, shared records, and other applications all draw on its programmable coins in different ways. The continued development of those tools, alongside the farming system, will shape how broadly Chia is used. (docs.chia.net)

Summary

Chia combines storage-based farming with a programmable public blockchain. XCH rewards farmers, pays fees, and moves between users and applications. Chialisp, asset tokens, and Offers extend the chain beyond basic payments, while projects involving shared data and financial products show practical uses of those tools. Its distinctive place in cryptocurrency comes from the pairing of proof of space and time with a coin-set approach to digital assets. (docs.chia.net)
