From Pi's Previous Dreams to Pi Ecosystem Reality: An In-Depth Review of Pi Network's Five-Year Development History

Before Pi, there was no truly mobile cryptocurrency in the internet era. Now, Pi Network has hundreds of millions of users worldwide. What story does this five-year transformation tell? This article will explore the project’s development from its innovative starting point, explosive growth, technological breakthroughs, to controversy and responses.

The Dilemma Before Pi: Two Stanford Doctors’ Innovative Thinking

In the crypto world before Pi, mining meant high energy consumption and high barriers to entry. Bitcoin mining rigs consumed more electricity annually than the entire country of Argentina, sparking thoughts among two Stanford PhDs.

Nicolas Kokkalis holds a PhD in computer science from Stanford, where he was a blockchain instructor and active member of the Blockchain Research Center. He graduated with a bachelor’s in computer science from the University of Crete in Greece, then earned a master’s in computer science from the University of Toronto.

Alongside him is Chengdiao Fan, a Stanford PhD in Human Behavior and Social Sciences, focusing on human-computer interaction and social computing—how technology can positively influence human behavior and society. She is Chinese; among her Stanford classmates is a well-known figure, Priscilla Chan, wife of Facebook founder Mark Zuckerberg.

Their core idea: can citizens worldwide participate in a crypto network using only their phones? This previously unmentioned idea became the engine behind Pi Network’s birth. The core team also includes Stanford alumni like Vincent McPhillip.

The Social Fission Era: From 3 to 33 Million Users

Launch and Early Expansion (2019-2020)

On March 14, 2019, Pi Network officially launched its iOS beta app on Pi Day, pioneering mobile mining—users could earn tokens by tapping a lightning button once every 24 hours. This design was unheard of in the crypto world before Pi.

Two months later, on May 22, the Android version launched, surpassing 100,000 users globally. But the real explosion was just beginning.

The concept of “mining by daily tapping” spread rapidly. From Shibuya Station in Tokyo, Bangalore, Lagos, users shared QR codes at cafes, dorms, offices. By day seven, Hanoi, Vietnam, saw its first “mobile farm”—twenty old phones charging in a cafe, screens flashing lightning icons. By day 90, Spanish tutorial videos had over a million views, and housewives in Argentina formed the “Pi Moms Alliance.”

By Christmas 2020, Pi Network covered 170 countries with over 3.5 million registered users. Offline parties appeared even in Seoul’s Gangnam district, while regulators in Manila had already issued warnings unnoticed.

White Paper and Testnet Era (2019-2021)

In December 2019, Pi released White Paper V1, outlining a three-phase roadmap: Phase 1 for token distribution (closed mainnet), Phase 2 for testnet (launched March 2020), and Phase 3 for mainnet launch.

By March 2020, testnet nodes exceeded 10,000. Crucially, this phase introduced the “security circle” mechanism, requiring users to link 3-5 real contacts to enhance network security. This design was unprecedented before Pi and unexpectedly fueled explosive user growth.

In April 2021, the Pi Browser (a decentralized app browser) launched. In June, KYC solutions using machine learning combined with manual verification were introduced. In November, White Paper V2 was released, announcing the mainnet launch in December.

Technological Breakthroughs: From Testing to Reality

On December 28, 2021, after years of preparation, the Pi mainnet officially went live, still in a closed network state, without free transfer capabilities. This was a promise made before Pi and a milestone for the project.

By March 2022, user count exceeded 33 million, but mainnet transfers remained limited to verified members for testing. In September, Pi Ad Network was launched, promising to distribute 50% of ad revenue to node operators.

Controversies and Reflection: How Pre-Pi Skepticism Turned

Regulatory Challenges and Community Disputes

As scale increased, doubts arose. In January 2023, South Korea’s Financial Services Commission listed Pi Network as a high-risk investment warning. By June, the core team announced 35% completion of the mainnet migration checklist. In October, reports emerged of offline merchants in Vietnam, Indonesia accepting PI as payment, later confirmed mostly as community-driven actions—highlighting the tension between community enthusiasm and cautious regulation.

Analysts pointed out that Pi’s dissemination structure is ten times more complex than multi-level marketing, which was a common criticism before Pi.

The Reality of Expectations: From Dream to Reality

In February 2025, PI was listed on top-tier exchanges as scheduled. The deposit opening was on February 12, with auction bidding from 3 PM to 4 PM on February 20, and spot trading officially started at 4 PM, synchronized with Pi Network’s mainnet launch. Five minutes before spot trading, market orders were prohibited; maximum limit orders and holdings were capped at $10,000.

This marked Pi’s transition from pre-launch expectations to reality, and the community’s faith was somewhat validated by the market.

Current Evaluation: The Truth After Dream Realization

As of March 2026, PI’s market data:

• Current Price: $0.20 per coin
• 24-hour Change: +0.53%
• 24-hour Trading Volume: $6.47 million
• Market Cap: $1.95 billion
• Circulating Supply: about 9.7 billion coins
• Total Supply: about 14.9 billion coins
• Circulation Rate: 9.71%

Compared to the original report’s circulating supply of 6.04 billion and total supply of 9.29 billion, the current circulating amount has increased by about 61%, reflecting ongoing development and a stable user base. The circulation rate is only 9.71%, indicating most PI tokens are still not in circulation, leaving significant room for future market movements.

Community Perspectives

Some believe that after years of effort, the Pi community has reached top exchanges with strong conviction, high consensus, and serves as a model for other communities.

Others, including industry insiders like Ben Zhou, express concern. They worry that the community’s trust might be too strong, and whether such enthusiasm can withstand market volatility.

The expectations for mobile crypto before Pi have been realized, but whether this success can withstand market tests remains to be seen. Time will tell.
