The story of blockchain in China is incomplete without talking about the rise of cryptocurrency mining. While blockchain technology began gaining attention globally, it was the mining industry that first took root in China—and flourished like nowhere else. At the heart of this transformation stood a pivotal technological breakthrough: the invention of ASIC miners. This is the story of how one passionate young engineer changed the course of crypto history.
From Anime Enthusiast to Mining Pioneer
In 2011, a graduate student at Beihang University named Zhang Nangeng was living a relatively quiet academic life. By day, he pursued his studies in aerospace engineering; by night, he immersed himself in anime—reportedly watching nearly 500 episodes a year. But beneath this seemingly ordinary routine was a fiercely independent and idealistic mind, one that would soon disrupt the entire world of Bitcoin mining.
Zhang’s journey into crypto began when he stumbled upon Bitcoin during its early days. At the time, mining was still a hobbyist activity. Most people used their personal computers—specifically CPUs and later GPUs—to mine coins. While GPU mining offered better performance, the differences in computing power were not extreme enough to create a significant competitive gap.
That changed in mid-2011 with the introduction of FPGA (Field-Programmable Gate Array) miners. These devices delivered a massive leap in efficiency, offering tens or even hundreds of times more hashing power than traditional GPU rigs. For tech-savvy individuals like Zhang, this was both a challenge and an opportunity.

Building the Future in a University Lab
Leveraging his background in engineering—having worked for three years at a state aerospace technology firm before returning to school—Zhang saw a way to combine technical skill with financial independence. He began developing his own FPGA-based mining hardware in his university lab, driven by both curiosity and the need to support himself.
To promote his prototype, Zhang joined the influential Bitcoin forum Bitcointalk under the username "ngzhang"—a handle that would soon become legendary in mining circles. His active participation and technical insights earned him respect and visibility within the nascent crypto community. He wasn’t just building machines—he was building credibility.
Under normal circumstances, Zhang might have completed his doctorate and entered a stable career in engineering or research. But fate—and a growing sense of urgency—had other plans.
The Threat That Sparked a Revolution
In 2012, news broke on Bitcointalk that stunned the Bitcoin world: a U.S.-based group called Butterfly Labs announced they were developing ASIC (Application-Specific Integrated Circuit) miners—machines designed specifically for mining Bitcoin with unprecedented efficiency. Even more alarming? They intended to keep these machines for themselves, not sell them publicly.
If Butterfly Labs succeeded, they could dominate Bitcoin’s network hash rate, potentially centralizing control over what was meant to be a decentralized system. To many idealists in the community, this threatened the very foundation of Bitcoin.
For Zhang Nangeng, it was a call to action.
Driven by principle and a strong sense of mission, he decided to build an open, accessible ASIC miner to counter Butterfly Labs’ monopoly. He approached his university advisor to request a leave of absence to focus on the project. When his request was denied, he made a bold choice: he dropped out of school to pursue mining full-time.
Reflecting later, Zhang said:
“I got into mining because I believed Butterfly Labs was misleading people. If no one stepped up, the entire industry would collapse.”
The Birth of Avalon and the Dawn of Modern Mining
Whether through sheer talent or extraordinary timing, Zhang succeeded where others hesitated. In a dramatic turn of events, he beat Butterfly Labs to market by launching the world’s first commercially viable ASIC miner: the Avalon.
Named after the mythical fortress in the anime Fate/stay night—symbolizing impenetrable defense—the Avalon represented a new era of security and efficiency in mining. Its performance dwarfed existing FPGA and GPU setups, making older methods obsolete almost overnight.
In April 2013, Zhang co-founded Canaan Creative (Jiannan Yunzhi) with his friend Li Jiaxuan. The first batch of Avalon miners sold out instantly, marking the official arrival of industrial-scale cryptocurrency mining.
Zhang became the first "dragon-slayer" in mining history—overthrowing old paradigms and ushering in a new age defined by capital investment, technological arms races, and exponential growth in computational power.

Yet Zhang’s triumph was only half the story. Even as Avalon reshaped the landscape, another figure was rising in parallel—one whose approach would contrast sharply with Zhang’s engineering-driven path.
This man was Jiang Xinyu—better known by his online alias: "Fried Cat" (Kao Mao).
Where Zhang represented technical rigor and precision, Fried Cat embodied community-driven innovation and decentralized funding. His emergence would mark the beginning of mining’s golden age—one fueled not just by hardware, but by vision, collaboration, and ambition.

Frequently Asked Questions
Q: What does ASIC stand for, and why is it important for mining?
A: ASIC stands for Application-Specific Integrated Circuit. Unlike general-purpose processors (like CPUs or GPUs), ASICs are built for one specific task—in this case, solving cryptographic puzzles for blockchain networks. Their efficiency makes them far superior for large-scale mining operations.
Q: How did FPGA miners differ from ASICs?
A: FPGA miners are reprogrammable chips that offer flexibility and improved performance over CPUs/GPUs. However, they are less efficient than ASICs, which are hardwired for maximum optimization in mining tasks.
Q: Why was Butterfly Labs such a threat to Bitcoin?
A: By developing powerful ASIC miners and refusing to sell them publicly, Butterfly Labs risked centralizing control over Bitcoin’s network hash rate—a move that could compromise network security and decentralization.
Q: Who is considered the father of modern crypto mining hardware?
A: While several contributors played key roles, Zhang Nangeng is widely recognized as a pioneer for creating the first successful ASIC miner (Avalon), effectively launching the modern mining industry.
Q: Is mining still profitable with ASICs today?
A: Yes, but profitability depends on electricity costs, hardware efficiency, and market conditions. Industrial-scale mining farms using advanced ASIC models remain dominant in global hash rate distribution.
