Pi Network is a mobile-first cryptocurrency (a type of digital currency) that lets anyone mine its native coin, PI, by tapping a button in a free smartphone app once every 24 hours. Founded on March 14, 2019, by two Stanford University PhD graduates, Pi Network has grown to over 60 million registered users and launched its Open Mainnet on February 20, 2025.

Cryptocurrency is digital money. It exists only online, is secured by mathematics, and is not controlled by any government or bank. Pi Network runs its own blockchain, a shared digital record book where, instead of one bank keeping track of transactions, thousands of computers around the world verify and store them together. Pi Network is part of the broader Web3 movement, the idea of building an internet where users, rather than corporations, own their digital assets.

The native token of the platform is called PI, or Pi coin. The platform (Pi Network) and the coin (PI) are distinct: Pi Network is the app and ecosystem, while PI is the specific cryptocurrency you mine and spend within it.

Pi Network was co-founded by Dr. Nicolas Kokkalis, who holds a PhD in Computer Science from Stanford University and specializes in distributed systems and human-computer interaction. His co-founder, Dr. Chengdiao Fan, holds a PhD in Computational Anthropology from Stanford, with expertise in how technology shapes human communities. Their academic backgrounds are publicly verifiable through Stanford's records and the Pi Network official website. The project is headquartered in San Francisco, California.

How Does Pi Network Work?

Pi Network operates on a fundamentally different model from Bitcoin and most other cryptocurrencies. Instead of requiring powerful computers to validate transactions, it lets anyone participate through a free smartphone app with no computational work involved.

The term "mining" in Pi Network does not mean what it means in Bitcoin. No cryptographic calculations occur on your phone. Pi Network uses the word to describe your daily participation in the network's trust and validation process. Understanding this distinction is the key to understanding the whole project.

Mobile Mining: How Pi Mining Works on Your Phone

Pi mining is like earning loyalty points on your phone. You check in once a day and earn a reward without doing any heavy lifting.

Your phone performs no mathematical calculations. No processor power is used, no battery is drained beyond a normal app open, and no specialized equipment is needed. Your mining rate, measured in PI per hour, accumulates for 24 hours after each tap. Once that session expires, your rate stops until you tap again.

How to start mining Pi:

1. Download the Pi Network app from the iOS App Store or Google Play Store
2. Create your account using a referral code from an existing Pi Network member
3. Open the app once daily and tap the lightning bolt icon to start a 24-hour mining session
4. Add trusted contacts to your Security Circle to increase your mining rate

Unlike Bitcoin's Proof of Work mining, which requires specialized ASIC hardware and consumes large amounts of electricity, Pi Network's approach uses no computational power at all.

Ways to increase your mining rate:

• Add 3 to 5 trusted people to your Security Circle
• Invite new users with your referral link
• Complete KYC identity verification
• Run a Pi node (an advanced option for technically inclined users)

Security Circles: Pi Network's Trust System

A Security Circle in Pi Network is a group of 3 to 5 trusted people you add to your account to help verify your identity and increase your mining rate.

Security Circles are what make Pi Network fundamentally different from every other cryptocurrency. Rather than using energy-intensive hardware to secure the network, Pi Network uses a social trust graph. Picture overlapping circles: your circle connects to your contacts' circles, which connect to their contacts' circles, forming a web of verified human relationships across the entire network. When enough interconnected circles vouch for participants, the network can confirm that each user is a genuine person rather than a bot.

Security Circles work like vouching for someone. You are telling the network: I know this person, they are real, and I trust them.

This mechanism serves a specific security purpose: preventing Sybil attacks, where one person creates thousands of fake accounts to accumulate mining rewards fraudulently. A fake account cannot easily build a web of trusted human connections, so the trust graph filters them out naturally. Only add people you personally know and trust, because adding strangers defeats the security purpose and weakens your contribution to the network.

The protocol behind this system is called the Stellar Consensus Protocol (SCP). A consensus mechanism is the set of rules that helps all participants in a network agree on which transactions are valid. Pi Network uses a modified version of SCP, which is based on Federated Byzantine Agreement (FBA). FBA allows participants to reach network consensus without trusting every other node globally, meaning the network does not need energy-intensive computation to function. Pi Network adapted SCP to work with mobile devices and the Security Circle trust graph, placing it in a different category from Bitcoin (which uses Proof of Work) and Ethereum (which uses Proof of Stake).

SCP was originally developed by the Stellar Development Foundation for the Stellar blockchain. Pi Network's implementation is a modified adaptation. The two are entirely separate projects that happen to share a protocol foundation, not the same blockchain or ecosystem.

Pi Network vs. Bitcoin: Key Differences

Pi Network and Bitcoin share the same basic purpose: enabling people to send digital money without a bank. They take completely different approaches to how that works.

For a deeper look at how proof-of-work cryptocurrencies like Bitcoin operate at the technical level, see What Is Bitcoin: Complete BTC Guide and Ecosystem.

Is Pi Network Legitimate?

It is a reasonable question. The crypto space has seen many fraudulent projects, and Pi Network deserves the same scrutiny you would apply to anything asking for your personal data.

Yes, Pi Network is a real blockchain project. It has its own native cryptocurrency (PI coin), a published technical whitepaper, verified founders with traceable credentials, and a launched mainnet as of February 2025.

When evaluating any cryptocurrency project for legitimacy, the standard checklist includes: a verifiable team, a published whitepaper explaining the technology, a real and functioning product, and a network that has actually launched. Fraudulent projects typically fail on at least one of these counts. Pi Network passes each. Pi Network has not been officially classified as a scam or fraudulent project by any regulatory authority, including the FTC or SEC, as of 2025. The Pi Network Whitepaper is publicly available and details the project's technical design, consensus mechanism, and token supply structure.

On the question of how Pi Network generates revenue: Pi Network has not publicly detailed a formal revenue model. Known mechanisms include in-app advertising and ecosystem transaction fees following the Open Mainnet launch. Future revenue may come from enterprise partnerships and developer fees within the dApp ecosystem, though these remain unconfirmed. This lack of a publicly stated revenue model is worth noting when evaluating the project's long-term commercial sustainability.

That said, passing a legitimacy checklist is not the same as guaranteeing future value or endorsing participation. The sections below lay out both sides of the evidence.

Signals That Support Legitimacy

Several attributes of Pi Network align with what distinguishes legitimate blockchain projects from fraudulent ones.

• Stanford-educated founders with verifiable academic credentials: Dr. Nicolas Kokkalis (PhD, Computer Science) and Dr. Chengdiao Fan (PhD, Computational Anthropology)
• Published whitepaper detailing the technical design, consensus mechanism, and token economics
• Over 60 million registered users as of 2025, making it one of the largest cryptocurrency communities by user count
• Open Mainnet launched on February 20, 2025, enabling real external blockchain connectivity for the first time
• PI coin listed and actively traded on OKX and Gate.io exchanges following the mainnet launch
• No money required to join: no ICO, no token sale, and no purchase is necessary
• App available on both the iOS App Store and Google Play with tens of millions of downloads

Legitimate Criticisms Worth Understanding

Pi Network also faces real criticisms that any prospective user should weigh honestly before participating.

• Centralization concerns: The Pi Core Team holds approximately 20% of the total token supply, giving the founding team significant influence over the ecosystem
• Delayed development timeline: The project spent years in an enclosed state before the Open Mainnet launched, and users had no guaranteed delivery date during that period
• KYC data collection: Submitting a government-issued ID and a selfie to a mobile app raises privacy questions, and users should review Pi Network's privacy policy before proceeding
• Large token supply: The 100 billion maximum PI token supply is orders of magnitude larger than Bitcoin's 21 million cap, a difference critics argue limits the potential per-token value
• Uncertain long-term value: PI coin's price has fluctuated since listing, and future value depends entirely on ecosystem adoption, which remains unproven at scale

Both the positive signals and the criticisms are real. The value section covers current PI coin pricing with the appropriate context.

Pi Network in 2025: The Open Mainnet Launch

Pi Network launched its Open Mainnet on February 20, 2025, marking the first time the project's blockchain connected to the broader cryptocurrency ecosystem after six years of development. This milestone separates Pi Network from cryptocurrency projects that promised a launch but never delivered one.

From Testnet to Open Mainnet: Pi Network's Development Stages

Pi Network moved through three key development stages from its 2019 founding to its 2025 Open Mainnet launch. Think of the progression like a software product moving from internal testing to a full public release.

Stage 1: Testnet (pre-2021). A testnet is an internal testing environment where transactions take place but carry no real-world value. Coins accumulated during this period were placeholders with no transferability outside the Pi ecosystem.

Stage 2: Enclosed Mainnet (2021 to 2025). Pi Network ran its own live blockchain during this phase. A mainnet is a live, fully operational blockchain, as opposed to a testnet, which is only a testing environment. During the Enclosed Mainnet phase, however, Pi's blockchain had no external connectivity. Coins could not be traded on exchanges, transferred to external wallets, or interacted with by outside parties.

Stage 3: Open Mainnet (February 20, 2025 to present). Full external connectivity launched. KYC-verified users can now migrate mined coins to their Pi Wallet. PI coin became tradeable on exchanges, and third-party applications can interact with the Pi blockchain for the first time.

This stage progression answers the frequently searched question about whether Pi Network has launched. It has. As of February 2025, Pi Network operates a fully open, externally connected blockchain.

Pi Network Roadmap After Open Mainnet

Pi Network's publicly stated roadmap targets several development goals following the Open Mainnet launch. These items reflect officially communicated plans and should not be taken as guarantees.

• Broader exchange listings beyond OKX and Gate.io
• dApp (decentralized application) ecosystem expansion through Pi Browser and Pi Apps
• Decentralized finance (DeFi) applications on the Pi blockchain, a long-term roadmap goal where financial services such as lending and borrowing would be built directly on the network
• Merchant adoption and broader PI coin spending utility
• Pi SDK for third-party developers building applications on the Pi network

Pi Coin Value and Tokenomics

PI coin became publicly tradeable for the first time following the Open Mainnet launch on February 20, 2025, with listings appearing on OKX and Gate.io.

Price disclaimer: Cryptocurrency prices change rapidly. The figures in this section reflect data available at the time of publication. For current PI coin price, market cap, and trading volume, check CoinMarketCap or CoinGecko. This article does not constitute investment advice.

PI Coin Price and Exchange Listings

PI coin trades on select cryptocurrency exchanges following the Open Mainnet launch.

A crypto exchange listing means a coin can be bought and sold on a public trading platform, where market participants set the price through supply and demand. Before the Open Mainnet, some exchanges listed PI as an IOU (I Owe You) token, a speculative instrument representing a future claim on PI rather than real PI coin. Those IOU listings were not backed by actual PI. Post-mainnet listings on OKX and Gate.io represent real PI coin trading.

PI is not yet listed on the largest global exchanges, such as Binance or Coinbase, as of this publication. The editorial team should verify current listing status before publishing, as the exchange landscape changes frequently. For current exchange listings and live price data, check the current PI coin price on CoinMarketCap.

PI coin's market cap is calculated by multiplying the current coin price by the number of coins in circulation. [Editorial: Insert current PI market cap from CoinMarketCap at publication time.] The fully diluted market cap uses the 100 billion maximum supply figure. Both metrics change daily and should be pulled from live data sources at publication.

For those asking whether PI coin's price will rise: no reliable prediction is possible. The coin launched on open exchanges in February 2025, the ecosystem is at an early stage of development, and the large token supply introduces variables that make forecasting inherently unreliable. The factors that could influence value over time include broader exchange adoption, growth of the Pi Browser dApp ecosystem, and general cryptocurrency market conditions.

Pi Network Tokenomics

Tokenomics refers to the economic rules governing a cryptocurrency's supply and distribution, along with the incentives built into the system. Think of it as the financial blueprint for how a coin works.

Pi Network's tokenomics are structured around a maximum supply of 100 billion PI tokens, allocated across four categories. The table below reflects figures from Pi Network's published whitepaper. Verify exact percentages against the current whitepaper before publication, as these figures are subject to update.

*Verify exact percentages against the current Pi Network Whitepaper before publication.

The mining reward rate decreases as the Pi Network grows, an approach analogous to Bitcoin's halving mechanism, where reward rates fall as the network matures. This is by design: early participants mine at higher rates, and the rate reduces as adoption expands.

The 100 billion maximum supply is significantly larger than Bitcoin's 21 million cap. Pi Network's stated design rationale is that mass adoption requires a supply accessible to billions of people. Whether that design choice benefits or limits per-token value is a question the market will answer over time.

What Can You Do With Pi Coins?

PI coins have four primary uses as of 2025.

1. Trade PI on cryptocurrency exchanges. OKX and Gate.io list PI for trading as of this publication. Verify current exchange availability before acting on this information.
2. Send PI peer-to-peer to other Pi Network users. Once coins are in your Pi Wallet, you can transfer PI directly to other users within the Pi ecosystem, with no bank or intermediary involved.
3. Spend PI in the Pi Browser marketplace. Pi Browser is a web3 browser integrated with the Pi Network ecosystem. Pi Apps is a growing marketplace of third-party decentralized applications (dApps, meaning apps built on a blockchain rather than on a company's private servers) where PI coins are accepted for goods and services. Pi Network's long-term goal is to build a dApp ecosystem similar to Ethereum's, though the Pi ecosystem is at an earlier stage of development.
4. Hold PI in your Pi Wallet while the ecosystem expands and broader merchant acceptance develops.

For those wondering whether PI can generate real money: it trades on exchanges at a market-determined price, so it carries monetary value in the same way any traded cryptocurrency does. Future value is uncertain, and no investment advice is offered here.

How to Get Started With Pi Network

Joining Pi Network takes about five minutes and costs nothing. No credit card, no cryptocurrency purchase, and no technical knowledge is required.

How to Join Pi Network: Step-by-Step

Follow these seven steps to download the app, create your account, and start mining PI coin.

1. Download the Pi Network app from the iOS App Store or Google Play Store (search "Pi Network")
2. Tap "Sign Up" and enter your phone number or connect via Facebook
3. Enter an invitation code from an existing Pi Network member (this step is required at registration)
4. Verify your phone number using the SMS code sent to your device
5. Tap the lightning bolt icon on the home screen to start your first 24-hour mining session
6. Add 3 to 5 trusted contacts to your Security Circle to increase your mining rate
7. Return to the app daily and tap the lightning bolt to keep your mining session active

On the invitation code: Pi Network requires a referral code from an existing member to register. This is not a marketing gimmick. The invitation-only system is part of Pi's Sybil resistance mechanism: only people with real human connections can join, which prevents mass fake account creation. If you do not have a code, ask any existing Pi user for theirs.

How to Complete Pi Network KYC

Yes, Pi Network requires all users to complete KYC (Know Your Customer) identity verification before mined coins can be accessed or transferred on the Open Mainnet.

KYC (Know Your Customer) is an identity verification step used by financial services worldwide, similar to what a bank requires when you open a new account. Pi Network uses KYC for two specific reasons: to prevent Sybil attacks (fake accounts fraudulently accumulating mining rewards) and to meet regulatory compliance standards that apply to financial services.

The KYC process collects a government-issued ID and a selfie. This is standard practice for financial apps. Data submitted for KYC is processed according to Pi Network's privacy policy, available at minepi.com.

How to complete Pi Network KYC:

1. Open the Pi Network app and navigate to the profile section
2. Locate the KYC verification option and tap to begin
3. Prepare a government-issued ID (passport, driver's license, or national identity card)
4. Follow the in-app prompts to scan your ID and take a selfie
5. Submit the verification and wait for review, as processing time varies by region
6. Upon approval, your mined PI coins become eligible for migration to your Pi Wallet

You can download the app and start mining without completing KYC. KYC is only required when you want to access and transfer your mined coins on the Open Mainnet.

Setting Up Your Pi Wallet

After completing KYC, you will set up a Pi Wallet, a non-custodial cryptocurrency wallet built into the Pi app where your mined coins are stored.

A crypto wallet is a digital tool that stores your cryptocurrency. The Pi Wallet is non-custodial, meaning you are the only person who controls your coins. Pi Network cannot access them. Think of it as a personal safe that only you hold the key to.

The key to your wallet is a 24-word passphrase generated inside the Pi app. Write this passphrase down and store it somewhere secure and offline. Losing the passphrase means permanent loss of access to your funds, with no recovery option, because no central authority holds a backup. Once your wallet is set up, migrate your mined PI balance from your mining account to the wallet. From there, you can send PI peer-to-peer to other users using their Pi username or wallet address.

Frequently Asked Questions About Pi Network

What is Pi Network and how does it work?

Pi Network is a mobile-first cryptocurrency project that lets users mine its native coin, PI, by tapping a button in a free smartphone app once every 24 hours. No hardware, electricity, or upfront cost is required. The network uses Security Circles (groups of 3 to 5 trusted contacts) and the Stellar Consensus Protocol to validate transactions. Pi Network launched its Open Mainnet on February 20, 2025, and PI coin is now tradeable on select exchanges.

Is Pi Network a legitimate cryptocurrency?

Pi Network is a real cryptocurrency project. It has Stanford-educated, verifiable founders (Dr. Nicolas Kokkalis and Dr. Chengdiao Fan), a published whitepaper, a live mobile app with over 60 million users, and an Open Mainnet that launched in February 2025. No regulatory authority has classified it as fraudulent as of 2025. Legitimate criticisms exist around centralization and uncertain future value, but these do not disqualify it as a real blockchain project.

Can you make real money with Pi Network?

PI coin has been publicly tradeable on OKX and Gate.io since the Open Mainnet launch in February 2025, so it holds real market value determined by supply and demand. Whether mining PI generates meaningful income depends on the coin's market price at the time you trade it. No returns are guaranteed. Future value is uncertain. Check CoinMarketCap for current pricing before making any financial decisions.

What is Pi Network used for?

PI coins have four current uses: trading on cryptocurrency exchanges (OKX, Gate.io), sending peer-to-peer transfers to other Pi Network users, spending PI in the Pi Browser marketplace (a growing library of third-party dApps), and holding PI in a Pi Wallet. Pi Network's long-term roadmap includes decentralized finance (DeFi) applications and broader merchant acceptance, though these remain aspirational goals as of 2025.

Is Pi Network free to use?

Yes. Pi Network is completely free. The app costs nothing to download, there are no fees to start mining, and no cryptocurrency purchase is required to participate. The only cost is time: roughly 30 seconds per day to tap the mining button. KYC verification (required to access mined coins) is also free, though it does require a government-issued ID.

How do I start mining Pi?

To start mining Pi, download the Pi Network app from the App Store or Google Play, sign up using an invitation code from an existing Pi member, and tap the lightning bolt icon on the home screen. This starts a 24-hour mining session. Return to the app once daily and tap again to keep your session active. Building a Security Circle of trusted contacts increases your mining rate.

What is a Security Circle in Pi Network?

A Security Circle in Pi Network is a group of 3 to 5 trusted people you add to your account. It forms the foundation of Pi's trust-based consensus system, the Stellar Consensus Protocol. Adding trusted people increases your mining rate and helps the network verify that all participants are genuine humans rather than automated fake accounts. Only add people you know personally, because adding strangers weakens the security of the network.

Has Pi Network launched its mainnet?

Yes. Pi Network launched its Open Mainnet on February 20, 2025, enabling external blockchain connectivity for the first time in the project's history. Before this launch, Pi operated in an Enclosed Mainnet phase (2021 to 2025) where its blockchain was live but had no external connectivity. The Open Mainnet allows KYC-verified users to migrate coins, trade PI on exchanges, and interact with third-party applications.

Is Pi Network available on crypto exchanges?

Yes. Following the Open Mainnet launch in February 2025, PI coin became tradeable on OKX and Gate.io. Before the Open Mainnet, some exchanges listed PI as IOU tokens, which were speculative proxies not backed by real PI coin. Those pre-mainnet listings are distinct from post-mainnet real PI coin listings. PI is not yet listed on major exchanges such as Binance or Coinbase as of this publication. Verify current listings at CoinMarketCap.

Who created Pi Network?

Pi Network was co-founded by Dr. Nicolas Kokkalis and Dr. Chengdiao Fan on March 14, 2019. Dr. Kokkalis holds a PhD in Computer Science from Stanford University and specializes in distributed systems. Dr. Fan holds a PhD in Computational Anthropology from Stanford, with expertise in how technology shapes human communities. Both founders' credentials are verifiable through Stanford University and the Pi Network official team page at minepi.com.

What is the Pi coin price?

PI coin's price is determined by market trading on OKX and Gate.io. Because cryptocurrency prices change continuously, no static figure in this article will remain accurate. For the current PI coin price, market cap, and 24-hour trading volume, check CoinMarketCap or CoinGecko directly. This article does not make price predictions or investment recommendations.

What is the difference between Pi Network testnet and mainnet?

Pi Network moved through three key stages: (1) Testnet (before 2021), an internal testing environment where coins had no real value; (2) Enclosed Mainnet (2021 to 2025), where Pi's own live blockchain ran but had no external connectivity or exchange trading; and (3) Open Mainnet (February 20, 2025 to present), where the blockchain connects to the broader crypto ecosystem, enabling exchange listings and real coin transfers. The Open Mainnet is the live, fully operational stage.

How many people use Pi Network?

Pi Network reports over 60 million registered users, referred to as Pioneers, as of 2025. This makes Pi Network one of the largest cryptocurrency communities by user count globally. The 60 million figure comes from Pi Network's official communications. Independent verification of active versus registered users is not available through third-party sources.

What can you buy with Pi coins?

As of 2025, PI coins can be used to trade on cryptocurrency exchanges (OKX and Gate.io), send peer-to-peer transfers to other Pi Network users within the Pi ecosystem, and spend PI in the Pi Browser marketplace on third-party dApps, including marketplaces, games, service apps, and more. Broader merchant acceptance and retail purchasing options are part of Pi Network's stated roadmap but are not yet widely available outside the Pi ecosystem.

Does Pi Network require KYC?

Yes. Pi Network requires all users to complete KYC (Know Your Customer) identity verification before mined coins can be accessed or transferred on the Open Mainnet. The KYC process involves submitting a government-issued ID and a selfie through the Pi app. You can download the app and mine without completing KYC, but KYC is mandatory before your mined coins become accessible. The process is handled within the Pi app and is free to complete.
