Unlocking Bitmain: The Hidden Empire Across the Bitcoin Ecosystem

·

In the fast-moving world of cryptocurrency, few companies have shaped the landscape as profoundly as Bitmain. From its humble beginnings to becoming a dominant force in the Bitcoin mining industry, Bitmain has quietly built an empire that spans hardware, mining pools, and even artificial intelligence. This is the story of how two visionaries turned a niche opportunity into a global powerhouse.

The Rise of Bitmain

Founded in 2013, Bitmain quickly rose to prominence by producing highly efficient ASIC (Application-Specific Integrated Circuit) chips tailored for Bitcoin mining. Today, seven out of every ten Bitcoin miners worldwide use Bitmain’s Antminer devices. More than half of all newly mined Bitcoins originate from Bitmain-affiliated mining farms. In just five years, the company climbed from obscurity to become one of China’s top chip design firms by revenue.

Its influence even reached Taiwan Semiconductor Manufacturing Company (TSMC). A $1.5 billion order from Bitmain in 2017 boosted TSMC’s computing division by 40% year-over-year—prompting executives to remark: “Everyone talks about AI, but Bitcoin is what’s really driving growth.”

Wu Jihan: From Evangelist to Power Player

At the heart of Bitmain’s rise is Wu Jihan, often called the “Bitcoin Evangelist.” He was the first to translate Satoshi Nakamoto’s whitepaper into Chinese and co-founded the influential Chinese Bitcoin community 8btc (Babt). His motivation? A deep belief in Bitcoin’s economic potential.

“Mainstream Chinese discussions were pessimistic,” Wu once said. “They saw Bitcoin as a pyramid scheme. We felt a responsibility to explain its value and technology clearly.”

His conviction wasn’t just philosophical. In 2011, he invested his entire savings into Bitcoin when it was worth just $0.30 per coin. By 2013, it had surged to $750—a 2,500x return that gave him both capital and credibility to dive deeper into the ecosystem.

The Birth of an Industry Giant

Wu’s journey into mining began with frustration. After suffering losses due to delayed shipments from a rival miner—ASICMiner (aka 'Friedcat')—he recognized a critical gap: reliable, high-performance hardware.

Friedcat had pioneered ASIC-based miners and briefly dominated the market. It even conducted a Bitcoin-denominated IPO in 2012, offering shares at 0.01 BTC each. A year later, dividends hit 0.038 BTC per share, and its stock peaked at 5 BTC.

But innovation stalled. As Bitmain and Canaan Creative launched superior models, Friedcat collapsed. Its founder vanished mysteriously in 2015—another chapter closed in crypto’s turbulent history.

Enter Jian Ketuan, Bitmain’s technical mastermind and Wu’s co-founder. A Tsinghua University graduate with extensive chip design experience, Jian assembled a team that rapidly developed BM1380, a 55nm mining chip that set new efficiency benchmarks.

Their first product, Antminer S1, launched in November 2013, gained immediate traction. But it was Bitmain’s resilience during the 2014–2015 Bitcoin bear market that cemented its dominance.

While competitors like Butterfly Labs and KnCMiner faltered, Bitmain kept innovating:

By late 2015, when Bitcoin prices rebounded, miners found one option overwhelmingly dominant: Antminer.

Building an Ecosystem: Beyond Hardware

Wu didn’t stop at manufacturing. He understood that control over mining infrastructure equates to influence over Bitcoin itself.

In September 2014, Bitmain acquired Snowball.io, rebranding it as Hashnest, a cloud mining platform. More significantly, in November 2014, it launched Antpool, which became the world’s largest mining pool within months.

Over time, Bitmain expanded its reach:

Today, over 60% of global Bitcoin hash rate flows through pools linked to Bitmain. What was meant to be a decentralized network now operates under centralized control—a paradox at the heart of modern Bitcoin.

To accelerate this growth, Bitmain introduced PACMIC, a hybrid product combining cloud mining with principal-guaranteed returns. Offered at over 10% annual yield, PACMIC attracted massive demand—raising millions in hours.

This financial innovation transformed Bitmain from a hardware vendor into a capital-efficient operator—akin to shifting from selling homes to leasing them long-term.

Global Expansion and Strategic Diversification

Despite China’s tightening crypto regulations post-2017, Bitmain adapted swiftly.

It established R&D centers in San Francisco, Israel, and the Netherlands, later accelerating international expansion:

But perhaps the boldest pivot was into artificial intelligence.

In November 2017, Bitmain unveiled Sophon, its AI brand, and the BM1680, claimed as the world’s first tensor processing unit (TPU) for deep learning. Named after the intelligent probe from Liu Cixin’s The Three-Body Problem, Sophon symbolized ambition: to challenge giants like Google and NVIDIA in AI computing.

Early applications focused on smart surveillance systems, including deployments in Xinjiang—home to some of Bitmain’s largest mining operations.

The Controversial Visionary

Why is Wu Jihan labeled a “villain” by some in the crypto community?

The answer lies in the Bitcoin Cash (BCH) hard fork of 2017.

To address Bitcoin’s scalability issues, Wu backed increasing block size—a move opposed by core developers who favored off-chain solutions like the Lightning Network.

Through Bitmain-linked pools like ViaBTC, Wu pushed forward a hard fork on August 1, 2017, creating Bitcoin Cash. Despite fierce resistance from the developer community, the fork succeeded—thanks largely to Bitmain’s control over mining power.

“Bitcoin Cash is its own entity,” Wu stated in an interview with Caixin. “It shares history with Bitcoin but follows an independent path.”

Critics accused him of undermining decentralization. Supporters praised him for enabling faster, cheaper transactions. Either way, Wu demonstrated that mining power translates directly into protocol influence.

Frequently Asked Questions (FAQ)

Q: What does Bitmain do?
A: Bitmain designs and manufactures ASIC chips and Bitcoin mining hardware (like Antminer), operates major mining pools (Antpool, BTC.com), and develops AI chips under its Sophon brand.

Q: Who owns Bitmain?
A: Co-founded by Wu Jihan and Jian Ketuan, ownership has evolved over time due to internal disputes and funding rounds. Both remain central figures in its history.

Q: Is Bitmain still dominant in mining?
A: While competition has increased from companies like Canaan and MicroBT, Bitmain remains one of the top players in ASIC production and mining pool operations.

Q: Why did Bitcoin split into BTC and BCH?
A: The split occurred due to disagreements over scaling. BTC kept smaller blocks with off-chain scaling; BCH increased block size for on-chain capacity—championed by Wu Jihan and Bitmain.

Q: Can one company really control Bitcoin?
A: No single entity controls Bitcoin entirely, but controlling significant hash power (as Bitmain once did) allows influence over transaction validation and protocol upgrades.

Q: What happened to Friedcat (ASICMiner)?
A: Once a pioneer, Friedcat collapsed due to failed chip development and the disappearance of its founder in 2015—an enduring mystery in crypto lore.

Final Thoughts

From translating a whitepaper to shaping the fate of digital currency, Wu Jihan’s journey mirrors Bitcoin’s evolution—from idealism to industrialization. Bitmain may no longer be the unchallenged king it once was, but its impact on the blockchain ecosystem is undeniable.

The era of decentralized dreams still lives on—but so does the reality of concentrated power. And in that tension lies the ongoing story of cryptocurrency.
