The long-awaited Open Mainnet launch of Pi Network on February 20, 2025, marks a pivotal moment in the history of decentralized digital currencies. After six years of community-driven development, technical refinement, and global expansion, Pi Network is transitioning from a closed ecosystem to a fully operational, open blockchain. This milestone isn’t just significant for its 70 million users—it represents a bold step toward democratizing cryptocurrency access for everyday people.
From its roots at Stanford University to becoming one of the most widely adopted mobile-first blockchain projects, Pi Network has redefined how individuals interact with crypto. Unlike traditional mining models that require costly hardware and massive energy consumption, Pi’s mobile mining model enables anyone with a smartphone to participate—ushering in a new era of inclusive finance.

The Origins of Pi Network
Launched on Pi Day (March 14, 2019), Pi Network was founded by Stanford graduates Dr. Nicolas Kokkalis and Dr. Chengdiao Fan. Their vision was simple but revolutionary: create a cryptocurrency that could be mined on mobile devices without draining battery or data. By doing so, they aimed to break down the financial and technological barriers that have historically excluded mainstream users from participating in blockchain ecosystems.
The project began as an experiment in decentralized trust, using a unique consensus mechanism based on social connections—known as the Social Consensus Algorithm—to secure the network without energy-intensive proof-of-work systems.
From day one, Pi Network emphasized accessibility, security, and community ownership. The referral system encouraged organic growth, allowing early adopters to earn additional rewards by inviting trusted friends and family. This grassroots expansion helped Pi grow to over 70 million users worldwide by 2025, with more than 19 million completing KYC verification and over 10 million successfully migrating balances to the Mainnet.
A Vision Realized: Building a People-Powered Blockchain
At its core, Pi Network was built on the belief that blockchain technology should not be controlled solely by mining farms or institutional investors. Instead, the founders championed the idea of a "cryptocurrency secured and operated by everyday people."
This philosophy shaped every phase of development. Rather than rushing to launch a token on exchanges, Pi took a deliberate, phased approach:
- Focused on building real utility before enabling trading
- Prioritized user verification (KYC) to ensure authenticity
- Developed tools for developers and businesses to build within the ecosystem
- Maintained full decentralization goals through community node participation
This cautious strategy paid off. By the time of the Open Mainnet launch, Pi Network already had a mature user base, a working economy, and hundreds of decentralized applications (dApps) ready for deployment.
Key Milestones Leading to Open Mainnet
Beta Phase (2019–2020): Laying the Foundation
The initial phase focused on testing the core concept: can millions of users mine a cryptocurrency securely via their phones?
- Launched mobile app in December 2018; official network launch on March 14, 2019
- Developed mobile mining infrastructure using low-power background processes
- Built the Trust Graph, a social consensus model where users verify each other’s legitimacy
- Reached over 3.5 million engaged Pioneers across 233 countries
- Established foundational security protocols to prevent botting and fraud
Testnet Phase (2020–2021): Validating the Blockchain
In March 2020, Pi launched its Testnet, marking the first live deployment of its blockchain architecture.
Key achievements during this stage:
- Rolled out distributed node infrastructure
- Released the Pi Browser and Software Development Kit (SDK)
- Enabled smart contract functionality for dApp creation
- Hosted the first Pioneer Hackathon, fostering developer engagement
- Grew to over 10,000 functional community-run nodes
This phase proved that Pi’s blockchain could scale and operate reliably under real-world conditions.
Mainnet Phase (2021–2025): Preparing for Global Adoption
The Mainnet rollout was divided into two strategic periods:
Enclosed Network Period (2021–2025)
- Implemented systematic KYC verification to ensure human participation
- Gradually migrated user balances from the legacy app to the secure Mainnet wallet
- Launched pilot programs for real-world transactions (e.g., Pi Fest)
- Tested economic models and inflation controls
- Refined security systems against Sybil attacks and fraud
Open Network Period (Starting February 20, 2025)
- Full external connectivity enabled
- Community nodes can now validate transactions
- Cross-chain integrations unlocked
- dApps can interact freely with external blockchains and services
- Public trading of PI tokens begins on major exchanges

What the Mainnet Launch Means for Users
For the millions of Pioneers who have mined Pi over the years, the Open Mainnet is more than just a technical upgrade—it’s a gateway to real-world value.
1. Global Accessibility and Liquidity
With the removal of restrictions, Pi coins (PI) can now be transferred freely outside the app ecosystem. This opens doors for:
- Listings on major cryptocurrency exchanges like OKX
- Peer-to-peer trading and remittances
- Integration with wallets and payment platforms
- Interoperability with other blockchains via bridges
Users who completed KYC and migrated their balances are now able to use PI as a functional digital asset.
2. Real-World Utility Is Here
Over 100 Mainnet-ready applications are already live, enabling Pioneers to spend PI on goods and services. Events like Pi Fest—where 950,000 buyers made purchases through 27,000 merchants—demonstrate growing adoption.
Use cases include:
- Online shopping and digital subscriptions
- Charity donations and tipping creators
- Local marketplace transactions
- In-game purchases in Pi-integrated games
3. Market Value Emerges
While no official price was set before Mainnet, market dynamics will now determine PI’s value based on supply, demand, and utility. Though speculative predictions range wildly—from fractions of a cent to thousands of dollars—the actual valuation will depend on sustained adoption and developer activity.

Opportunities for Developers and Entrepreneurs
The Open Mainnet isn’t just about users—it’s a launchpad for innovation.
Build dApps That Matter
Developers can now deploy smart contracts and decentralized applications directly on the Pi blockchain. With SDKs and APIs readily available, integrating Pi into existing dApps or creating new ones has never been easier.
Operate Community Nodes
Anyone can run a node to help secure the network and earn rewards. The Pi Core Team prioritizes verified contributors for node migration, ensuring decentralization remains robust.
Enable Business Adoption
Through Know Your Business (KYB) verification, companies can join the Pi ecosystem as official merchants. This allows them to accept PI payments, expand customer reach, and tap into a global user base.
Challenges and Criticisms Addressed
No project of this scale avoids scrutiny. Over the years, Pi Network has faced questions about:
- Delays in Mainnet launch
- Slow KYC processing times
- Concerns about centralization during early phases
- Misconceptions around referral incentives resembling pyramid schemes
However, transparency reports, open governance forums, and progressive decentralization have helped address these concerns. The successful migration of millions of users and the launch of a functional economy underscore Pi’s legitimacy.
Frequently Asked Questions (FAQ)
Q: Can I trade Pi coins now?
A: Yes—after completing KYC and migrating your balance to the Mainnet wallet, you can transfer PI to supported exchanges like OKX for trading.
Q: Is Pi Network a scam?
A: No. Pi Network is a legitimate blockchain project developed by Stanford PhDs with verifiable code, public testnets, and real-world use cases. It does not charge users to mine or withdraw funds.
Q: How much is one Pi coin worth?
A: The value is determined by market demand. There is no fixed price set by the Pi Core Team. Trading activity on exchanges will establish fair market value.
Q: Do I need to pay to complete KYC?
A: No. KYC verification is free. Beware of scams asking for payment—only use official Pi Network channels.
Q: Can I still mine Pi after Mainnet?
A: Mining continues during the Open Network phase but at a decreasing rate over time, following a predetermined emission schedule.
Q: What happens if I haven’t migrated my balance?
A: You must migrate your mined Pi from the old app to the Mainnet wallet via the official process. Unmigrated balances remain inactive until migration is completed.
