The Last Ethereum Miners and China’s Mining Legacy
Key Takeaways:
- Ethereum completed its transition from PoW to PoS on September 15, 2022, marking the end of an era.
- China once dominated global mining with 75% of Bitcoin’s hash rate before the 2021 crackdown.
- NVIDIA’s GPU sales surged due to Ethereum mining, generating $3B in 2021 revenue.
- The Merge shifts focus to staking, reducing energy consumption by 99.95%.
The Pre-Mining Era (2010-2014)
Bitcoin’s Pizza and Early Mining
In May 2010, programmer Laszlo Hanyecz made history by trading 10,000 BTC for two pizzas ($30), giving Bitcoin its first valuation: **$0.003**. This sparked a gold rush, with early miners like Hal Finney earning thousands of BTC using simple CPU setups.
By 2011, GPU mining took over, and ASIC (Application-Specific Integrated Circuit) machines emerged. Chinese innovators like "Pumpkin Zhang" (Zhang Nanheng) and "Fried Cat" (Jiang Xinyu) pioneered ASIC rigs, laying groundwork for China’s mining dominance.
Vitalik’s Vision
Meanwhile, a 17-year-old Russian-Canadian prodigy, Vitalik Buterin, explored Bitcoin’s decentralized potential. After co-founding Bitcoin Magazine in 2011, he proposed Ethereum in 2013—a Turing-complete blockchain for smart contracts.
"PoW leads to centralization through ASICs. PoS is Ethereum’s future."
—Vitalik Buterin, Ethereum Whitepaper
China’s Mining Boom Meets Ethereum (2014-2016)
Mining Giants Rise
- Bitmain: Founded by Jihan Wu in 2013, it dominated with Antminer S1.
- ASICMINER: Jiang Xinyu’s IPO-funded operation earned ~$20M in 3 months.
- Avalon: Zhang Nanheng’s rigs became the backbone of Chinese mining.
By 2015, China controlled 75% of global Bitcoin hash rate.
Ethereum’s Rocky Start in China
Vitalik’s 2014 China tour faced skepticism. Investors dismissed Ethereum as a "scam," but Wanxiang Blockchain’s Xiao Feng invested $500K, saving the project. Key milestones:
- July 2015: Frontier launched—Ethereum’s first live network.
- March 2016: Homestead upgrade improved stability.
The DAO Hack and Fork
In June 2016, a $60M exploit split Ethereum into ETH (current chain) and ETC (classic chain). The controversial hard fork set a precedent for future governance.
The ICO Craze and NVIDIA’s Windfall (2017-2019)
Ethereum’s Killer App: ERC-20
2017’s ICO boom saw 94% of top-100 crypto projects built on Ethereum. Highlights:
- $60B+ raised via token sales.
- Gas fees skyrocketed with dApps like CryptoKitties.
NVIDIA’s Crypto Goldmine
Ethereum’s Ethash algorithm favored GPU mining, driving unprecedented demand for NVIDIA cards:
- 2017: Revenue jumped 40% to $9.7B.
- 2021: Mining chips added $3B in sales.
CEO Jensen Huang capitalized on the trend, releasing CMP矿卡 (dedicated mining GPUs).
The Road to Proof-of-Stake (2020-2022)
DeFi Summer and London Fork
- 2020: DeFi TVL hit $30.5B; NFTs exploded.
- 2021: EIP-1559 burned ETH, reducing miner rewards.
The Merge: September 15, 2022
Ethereum’s PoS transition:
- Energy use: Dropped from 112 TWh/year to ~0.01 TWh.
- Staking: Over 27M ETH ($50B) locked post-Merge.
FAQs
1. Why did Ethereum switch to PoS?
To reduce energy consumption, improve scalability, and decentralize validation.
2. What happened to GPU miners post-Merge?
Many switched to ETC or sold equipment; NVIDIA’s mining revenue fell 66%.
3. How does staking work in Ethereum 2.0?
Validators lock 32 ETH to earn rewards (~5% APR). Services like Lido offer liquid staking.

Conclusion: The Next 8 Years
Ethereum’s journey continues with:
- Sharding: To boost TPS beyond 100,000.
- Layer 2 solutions: Rollups (Optimism, Arbitrum) scaling dApps.
"The Merge isn’t the endgame—it’s the foundation for Web3’s future."
