$PI Here is a concise, coherent, and engaging summary of the entrepreneurial story of Fan Chengdiao & Dr. Nicholas, suitable for reading.

1. Meeting: The "Technology + Humanity" Combo at Stanford

Fan Chengdiao was born in Anshun, Guizhou. He studied at Minzu University of China for his undergraduate, then went to Stanford for a Ph.D. in Human-Centered Computing, focusing on the relationship between people, society, trust, group behavior, and technology.

Nicholas is of Greek descent, with a Ph.D. in Computer Science from Stanford, specializing in distributed systems, blockchain, and smart contracts. He researched similar smart contracts before Ethereum existed and taught a blockchain course CS359B at Stanford.

They met, fell in love, and became a married couple at Stanford. People around them say:

- Nicholas: A technical idealist, understands code, systems, and how to make technology stable.
- Fan Chengdiao: A human-centered designer, understands users, culture, and how to make technology accessible to ordinary people.

Their shared pain point:

"Blockchain is too energy-consuming, too elitist, too speculative—ordinary people simply can't get in."

2. Original Aspiration: Creating a "Blockchain Usable by Ordinary People" (2017–2018)

In 2017, Bitcoin exploded in popularity, but Nicholas saw:

- Mining farms roaring, huge electricity consumption
- Only the wealthy and tech-savvy could participate
- Ordinary people being shut out

Fan Chengdiao proposed from an anthropological perspective:

"Why not replace expensive mining rigs with mobile phones + social trust?"

Over late-night talks in Stanford cafes and labs, they gradually formed an idea:

- No mining rigs, mobile phone mining
- No energy-intensive computation, use social trust circles for consensus
- Not just for trading, but for inclusive, fair, and accessible digital identities for everyone

In 2018, they officially decided to start a project named Pi Network (π), symbolizing "Pi: accessible to all, infinite, decentralized."

3. Starting Out: No Money, No People, Not Promising (2018–2019)

Early days were very tough:

- No big capital, relying on Stanford's StartX incubator and their savings
- Investors questioned: "Social mining? Violates blockchain's anonymity spirit, won't grow big."
- Small team: just the couple plus 1–2 Stanford alumni, sketching models on shared office whiteboards

Fan Chengdiao handled:

- Product design, user mechanisms, trust circles (trust mining)
- Turning anthropological theories into executable rules: preventing monopolies, cheating, ensuring fair distribution

Nicholas handled:

- Underlying blockchain architecture, consensus algorithms, security
- Insisted on no backdoors, no pre-mining, no large team holdings

On Pi Day, March 14, 2019, Pi Network officially launched with a simple mobile app:

- Tap once daily for quick, free mining
- No data traffic, no energy, no hardware needed

4. Explosion: From Zero to Tens of Millions of Users (2019–2021)

After launch, growth relied entirely on word of mouth:

- No ads, no marketing expenses
- Viral spread from the US → China → Southeast Asia → Africa → Latin America

Fan Chengdiao’s social design played a huge role:

- Inviting friends, building trust circles
- More users = safer network, more stable mining
- Turning "social connections" into "network security," not pyramid schemes

Nicholas withstood pressure:

- Refused short-term profit collaborations
- Rejected capital control demands: "We want decentralization, not capital centralization."

By 2021, global users exceeded 30 million across 200+ countries, becoming one of the largest inclusive blockchain communities worldwide.

5. Staying True: The Tug Between Ideals and Reality (2021–2026)

After gaining fame, controversy and temptations arose:

Temptations:

- Many exchanges and capital looking to list: "Get listed, cash out, make a quick profit."
- The team could instantly become wealthy

Their choices:

- Refused to list on exchanges, private placements, fundraising, pre-mining
- Stuck to: build an ecosystem, prioritize decentralization, develop practical applications before discussing value

Fan Chengdiao often says:

"We're not here to issue tokens; we're here to build an internet value layer that ordinary people can use."

Nicholas emphasizes:

"If blockchain is just a casino, it loses its meaning. What we want is technological democracy, digital fairness, and participation for everyone."

In recent years, they focused on:

- KYC (identity verification)
- Wallets, browsers, DApp ecosystems
- Transition from closed mainnet to open network
- Governance decentralization, community autonomy

6. Today: A Long-term Vision of a Scholar Couple

By 2026:

- Over 33 million Pi users worldwide
- Still not listed on mainstream exchanges
- The team remains committed to no exit scams, no hype, no promises of quick riches
- Goal unchanged: a truly decentralized public chain owned by ordinary people

Their entrepreneurial story boils down to one core idea:

Two Stanford PhDs, abandoning the elite shortcut, choosing the hardest path—restoring blockchain to the hands of ordinary people.
