Ethereum’s transition from Proof-of-Work (PoW) to Proof-of-Stake (PoS) marked the end of an era — an 8-year chapter defined by GPU mining, explosive innovation, and a deep connection with China’s booming crypto mining industry. This shift didn’t just alter Ethereum’s technical backbone; it reshaped the global landscape of blockchain infrastructure, impacted hardware giants like NVIDIA, and redefined the role of miners in Web3.
The Rise of Crypto Mining: From CPUs to ASICs
In the early days of cryptocurrency, mining was accessible to anyone with a computer. The first Bitcoin transactions were processed using CPUs, and early adopters like Hal Finney mined thousands of BTC from their home desktops. But everything changed in 2010 when a programmer famously traded 10,000 BTC for two pizzas — giving Bitcoin its first real-world valuation.
As Bitcoin gained value, competition intensified. Enthusiasts turned to GPUs for greater processing power, sparking a technological arms race. This wave quickly reached China, where tech-savvy entrepreneurs saw opportunity. Figures like Wu Jihan (founder of Bitmain), Zhang Nangeng (“Pumpkin Zhang”), and Jiang Zhuoer (“Fried Cat”) emerged as pioneers, building some of the first ASIC miners — specialized hardware designed solely for cryptocurrency mining.

While Bitcoin mining became dominated by ASICs — leading to centralization due to high capital costs — Ethereum took a different path. From its inception, Ethereum aimed to remain accessible to individual miners using consumer-grade GPUs, thanks to its Ethash algorithm, which is resistant to ASIC dominance.
Vitalik Buterin and the Birth of Ethereum
Long before he became known as “V God” in China, Vitalik Buterin was a curious teenager fascinated by decentralized systems. His disillusionment with centralized game mechanics in World of Warcraft planted the seeds for his future vision: a world where no single entity controls the rules.
After co-founding Bitcoin Magazine at just 17, Vitalik began envisioning a blockchain beyond payments — one capable of running smart contracts. In late 2013, he released the Ethereum whitepaper, proposing a Turing-complete blockchain platform. Unlike Bitcoin, Ethereum would allow developers to build decentralized applications (dApps) on a shared infrastructure.
The project gained traction quickly, especially after Buterin received the $100,000 Thiel Fellowship. He moved development to Zug, Switzerland — soon dubbed “Crypto Valley” — and launched Ethereum’s ICO in 2014, raising over 31,000 BTC (around $18 million at the time).
But initial reception in China was cold. During a 2014 visit, Vitalik was dismissed as a scammer by prominent figures in the crypto space. Few believed in the potential of smart contracts. As one early investor later admitted: “99% of China’s crypto community missed this opportunity.”
China’s Role in Early Ethereum Adoption
Despite early skepticism, China soon became central to Ethereum’s growth — not through venture funding, but through grassroots mining and community building.
After Bitcoin’s mining ban in mid-2021 disrupted China’s PoW ecosystem, many miners pivoted to Ethereum. With lower entry barriers and GPU-based mining, Ethereum offered a lifeline. Chinese pools like Sparkpool rose to prominence, contributing significantly to network security.
Communities such as EthFans and ECN played pivotal roles in translating documentation, hosting meetups, and supporting developers. Xiao Feng, former CEO of Wanxiang Blockchain Labs, became one of Ethereum’s earliest institutional supporters in China, investing $500,000 — funds Vitalik later called “a lifeline” for the project.
The ICO Boom and Ethereum’s Ascendence
2017 marked Ethereum’s breakout year. The launch of ERC-20 tokens revolutionized fundraising, enabling hundreds of Initial Coin Offerings (ICOs) to raise billions. Projects built on Ethereum flooded the market, driving demand for ETH and pushing prices from under $10 to over $1,400 by early 2018.
This boom created a feedback loop: more dApps → more transactions → higher gas fees → greater miner rewards → increased network security. However, it also exposed scalability issues. The infamous CryptoKitties game clogged the network, highlighting Ethereum’s limitations.
Meanwhile, GPU demand skyrocketed — and NVIDIA found itself at the center of a gold rush.
NVIDIA: The Unintended Beneficiary of Ethereum Mining
While Bitcoin mining favored ASICs made by companies like Bitmain, Ethereum’s Ethash algorithm relied heavily on GPU memory bandwidth — making NVIDIA’s GeForce series ideal for mining.
Between 2016 and 2018, NVIDIA’s market cap surged from $14 billion to $175 billion. In 2017 alone, the company reported $9.7 billion in revenue — though it attributed most of it to gaming. Behind the scenes, however, miners were snapping up GTX 1060s and P106 “mining-only” cards in bulk.
NVIDIA initially denied any significant crypto impact on sales — until reality set in. When the 2018 bear market hit, miners dumped used GPUs, flooding the market and crashing prices. NVIDIA’s Q4 revenue plummeted, forcing it to revise guidance downward.
The cycle repeated in 2021. During the DeFi and NFT boom, Ethereum’s price neared $3,000, reigniting GPU demand. NVIDIA responded with CMP (Cryptocurrency Mining Processor) chips — purpose-built for mining without display outputs.
Yet even these efforts couldn’t mask the writing on the wall: Ethereum’s shift to PoS was inevitable.

The Long Road to Serenity: Ethereum’s Move to Proof-of-Stake
Ethereum’s roadmap always included a transition to PoS — outlined in four phases: Frontier, Homestead, Metropolis, and Serenity.
- Frontier (2015): Launched with PoW to bootstrap network security.
- Homestead (2016): Stabilized the network; introduced Mist wallet.
- Metropolis (2017–2019): Implemented Byzantium and Constantinople upgrades; reduced block rewards and delayed the “difficulty bomb.”
- Serenity (2022): Completed the Merge — ending PoW mining forever.
The Merge wasn’t just an upgrade — it was a revolution. Overnight, over 99% of Ethereum’s energy consumption vanished. Validators replaced miners. Staking became the new norm.
For miners, the end came swiftly. Ethermine, once responsible for 33% of Ethereum’s hashrate, shut down its PoW operations. Secondary GPU markets flooded with used cards. Analysts estimate that more than one-third of consumer GPU demand disappeared post-Merge.
What Comes After Mining?
With mining gone, Ethereum faces new challenges:
- Scalability: Can Layer 2 solutions like Rollups deliver mass adoption?
- Decentralization: Is staking centralizing control among large entities?
- Censorship Resistance: Can PoS maintain immutability under regulatory pressure?
These questions define Ethereum’s next era — one no longer powered by graphics cards, but by code, consensus, and community.
FAQ
Q: When did Ethereum stop mining?
A: Ethereum officially ended Proof-of-Work mining on September 15, 2022, with the completion of “The Merge,” transitioning fully to Proof-of-Stake.
Q: Why did Ethereum move from mining to staking?
A: To improve scalability, reduce environmental impact (cutting energy use by ~99.95%), and enhance network security through economic incentives rather than computational power.
Q: What happened to Ethereum miners after the Merge?
A: Most miners either sold their GPUs, switched to other PoW chains like Ethereum Classic (ETC), or repurposed hardware for AI training or gaming rigs.
Q: Did NVIDIA lose money after Ethereum stopped mining?
A: Initially yes — GPU prices dropped and inventory piled up. But NVIDIA pivoted successfully toward AI and data centers, where its chips now dominate machine learning workloads.
Q: Can I still earn ETH without mining?
A: Yes — through staking. Users can stake ETH directly or via services like Lido or Coinbase to earn rewards while helping secure the network.
Q: Is Ethereum fully upgraded now?
A: Not yet. The Merge was just one phase. Future upgrades like sharding aim to further boost speed and lower costs for users.

Looking Ahead: The Next Chapter
Eight years ago, Ethereum began as a bold idea — a programmable blockchain powered by miners around the world. Today, it stands as the foundation of Web3, hosting DeFi protocols, NFTs, DAOs, and countless innovations.
The end of mining isn’t an endpoint — it’s a transformation. As Vitalik Buterin once said: “The goal isn’t just to make money; it’s to build systems that last.”
Now, developers, validators, and users carry that mission forward — not with GPUs humming in warehouses, but with wallets secured in software and ideals rooted in decentralization.
The mining era is over. The real work begins now.
